Page 1 of 3 AGENDA ITEM – 3A MEMORANDUM DATE: June 23, 2025 TO: Honorable Mayor and City Councilmembers Jessica Jagoe, City Administrator FROM: Elena Fransen, Senior Planner SUBJECT: Planning Case 25-004 – Concept Plan Review Boston Scientific – Building 14 Screening Budgeted Amount: Actual Amount: Funding Source: N/A N/A N/A Council Should Consider The Council should consider a request for a Concept Plan Review, submitted by Boston Scientific (“Applicant”) for Building 14 on the Boston Scientific Campus property located at 4100 Hamline Avenue (“Subject Property”). The Applicant is seeking feedback from the City Council on a concept plan to install a barrier wall along the northwest corner of Building 14. The Concept Plan Review process is an opportunity for the City Council to provide comments and ask questions regarding proposed developments. A concept review is considered advisory and is nonbinding to the City and Applicant (Section 1320.14, Subd 4 of the Zoning Code). No formal action can be taken at a Work Session. A formal application will be subject to the full review process, including a public hearing with Planning Commission and City Council review. Background The Boston Scientific campus at 4100 Hamline Avenue North operates under a Planned Unit Development (PUD) that was originally approved in 2002 for the Guidant Corporation. The last update to the PUD and Campus Master Plan took place in 2021 when the City approved a 17,450 square foot addition to the south side of Building 14, a facility located in the northwest corner of the Arden Hills campus near Innovation Way (Planning Case 21-001). The purpose of this facility is the development and production of lithium batteries for use in medical devices. At the January 25, 2021 City Council meeting, the PUD Amendment for the Building 14 addition was approved as amended by 15 conditions. Conditions of approval included “12. Once the Project is completed and the equipment is operational, Applicant must conduct a noise study at the time of completion and occupancy permit and six months following Project completion and occupancy Page 2 of 3 to ensure the facility does not exceed maximum notice standards. If necessary, Applicant will take steps to correct any deficiencies.” and “13. Applicant will complete yearly noise studies on Building 14 and provide the results and findings to the City and take steps to correct any deficiencies that are identified by the studies.” Building permits for the addition were issued on September 28, 2021 and the temporary certificate of occupancy was issued as of December 27, 2022, subject to the required noise study once the building was operational. The first noise study was conducted in 2023 and the results were submitted to the City. In the study’s findings, it was identified that the noise from the facility exceeded the maximum noise standards, and the Applicant was required to take corrective action. It was determined that the source of the noise was due to an air compressor that was not part of the replacement equipment with the addition but was in existence prior to the project. The Applicant proposed a mechanical screen wall at the northwest corner of Building 14 for noise barrier and was issued a building permit on October 11, 2023 for its construction. The construction of the screen wall passed final building inspection as of March 18, 2024. Two additional noise studies were conducted in the first half of 2024 that verified the noise levels from the facility were within the permitted MPCA noise standards. The Applicant has remained compliant with the conditions of approval for the PUD Amendment and will need to continue to supply the City with the results from annual noise studies. Discussion Concept Plan Proposal The Applicant has provided a concept plan for the construction of a noise barrier wall to be constructed on the Subject Property between Building 14 and the adjacent city trail and residential properties to the northwest. The stated purpose of the barrier is to further reduce the level of Boston Scientific generated noise that leaves the campus and reaches adjacent neighborhood properties. The barrier wall installation is stated to help reduce noise while preserving a clean, attractive environment. The proposed noise barrier wall would extend 526 lineal feet and range in height from eight (8) feet to 21 feet as measured from existing grade. The proposed location of the wall would be offset from the property line and follow the curvature of the nearest property line which is shared with City-owned property where a trail is located. The proposed materials for the noise barrier wall are treated pine boards and precast concrete. Construction of the proposed wall would require the removal of significant trees on the Subject Property and the Applicant has stated that the proposed project would include significant landscape improvements to the Subject Property on the trail side of the barrier and the Building 14 side of the barrier. Based on an initial review, staff believes a future proposal would require a land use request for a Planned Unit Development Amendment due to the proposed height of the noise barrier wall. Per Section 1325.05 Design Standards Subd. 4 Screening, screens and buffers are designated units of yard or open area where setbacks, landscaping, berming, walls, and fencing help minimize adverse impacts of public nuisances, such as noise. In Section D. Fences of 1325.05, 4. Height of Fences in Business and Industrial Districts. Fences may be up to eight (8) feet in height in the side and rear yards up to the front building line of the principal structure. As the proposed wall would exceed 8 feet, City approval is required. Page 3 of 3 In the same section of the zoning code, item 9. establishes Fences in Non-Residential Situations and Exceptional and Unusual Circumstances in Residential Districts. Deviation from these requirements for fences, walls and landscape screening may be permitted after Planning Commission review and Council approval of a site plan with documentation showing the unusual circumstances justifying the proposed deviation and plans for the proposed fence, wall, or landscape screening. Tree removal associated with the proposed noise barrier wall would be subject to Section 1325.055 Tree and Landscaping Preservation in the Zoning Code. The City Engineer/Public Works Director has reviewed the noise barrier wall concept and provided comment that the placement/location of the wall should not impact City operations as the adjacent segment of trail is in such condition that it could easily fail if used during the project. Another note is a question of if the Applicant has a landscaping maintenance plan for the side of the wall adjacent to the City trail. Budget Impact N/A Attachments A. Land Use Application B.

Although meeting local noise compliance requirements, Boston Scientific desires to expand upon the progress made in recent years to reduce noise levels for nearby residents. The installation of a thoughtfully designed noise barrier wall will help reduce noise while preserving a clean, attractive environment for all. Success includes: Sound mitigation to support neighborhood well-being Tasteful construction materials for a natural look Refreshed landscape with native plantings to encourage healthy growth The objective of the analysis was to engineer a barrier wall design that helped reduce noise at residential receiver locations near Building 14 by 5 dBA, which is noticeably quieter. The analysis used hypothetical max conditions for equipment sources, which is common in engineering. The assumptions used for the engineering analysis were consistent with MPCA guidelines. Barrier Noise Analysis 2 BOSTON SCIENTIFIC - BLDG 14 NOISE BARRIER WALL | 4 ACOUSTICAL PERFORMANCE Boston Scientific Building 14 North SUMMARY BSC is committed to exceeding the State MPCA noise requirements. There are multiple acoustical benefits of the barrier wall: Reduces BSC vehicle and loading dock noise for the nearest neighbors. Reduces BSC operational noise for the nearest neighbors. Gives BSC flexibility to make changes to equipment without exceeding the noise requirements. BARRIER NOISE ANALYSIS The objective of the analysis was to engineer a barrier wall design that helped reduce noise at residential receiver locations near Building 14 by 5 dBA, which is noticeably quieter.

Background The City applied for grant money from Ramsey County’s recycling SCORE grant program for 2025. The City has primarily used the base funds to offset the cost of the City’s recycling program, including administration, equipment, and collection costs. There is incentive funding, in addition to the base allowance, that can be used for up to two approved incentive initiatives per year. In 2024 Arden Hills received $4,007.00 in incentive funds. The 2025 incentive amount is $23,815. Staff has been working with Ramsey County to determine which incentive initiatives may be eligible. A city may use SCORE incentives on an approved initiative but must expand the program, in order to use the same incentive type the following year. In the past the incentive funds have been used for the annual Cleanup Day event. Arden Hills has partnered with Recycle Technologies in Blaine. We are still planning to move forward with that event on October 4, 2025. We will continue to offer residents a coupon for two free items. Discussion Staff is proposing a one-time opportunity to expand on the annual fall cleanup day, and offer an additional cleanup option, in the city. Staff identified a vendor, Freimuth Enterprises, LLC to AGENDA ITEM – 3B MEMORANDUM Page 2 of 3 administer this additional event. Note the City of Lino Lakes has a regular, monthly program established utilizing this vendor that has been successful and highly utilized. Freimuth Enterprises, LLC will operate the cleanup event at a location in Arden Hills and residents can drop off accepted items for an established fee. As with the Recycle Technologies event, Freimuth Enterprises is willing to accept coupons for free items. The details of how many free items will be accepted per resident are still being explored. After the coupons, Residents will pay the fee on the pricing list. Please see Attachment A for Freimuth’s rate schedule as well as Attachment B for Recycling Technologies’ rate schedule, for comparison. Freimuth Enterprises, LLC bring their own staff and rolloff containers and they remove everything the same day. The base cost for this service to be onsite is $650.00, plus $2,000.00 for labor and would be covered by SCORE incentive dollars. One Public Works Employee would be needed onsite for the event, to ensure all collected items are removed the same day and to street-sweep the parking lot, if necessary. Staff has verified that SCORE incentive dollars can be used to cover our PW staff time during the event. Assuming an eight-hour day would be $538.00 (Note: For calculating staff time, a full eight-hour day was factored, but actual work time could be less based on event duration and time needed for contractor clean up, etc.). In addition to dropping off unwanted items, the City has the option to include paper shredding at the event, as well. The vendor that Freimuth has worked with at their other events is 1st Choice Document Destruction, Inc. and staff recommends securing this company to provide paper shredding services. Please note that SCORE incentive dollars could also be used to cover the expense related to the paper shredding service, which is $675 ($225 per hour x three hours) and residents could securely shred their personal documents, at no charge to the resident. Estimate costs of additional cleanup event: Freimuth Enterprises, LLC $ 2,650.00 1st Choice Documentation Destruction, Inc. $ 675.00 One City Employee $ 538.00_ Total (max cost of event) $ 3,863.00 We are proposing this as a one-time event as Ramsey County cannot guarantee that the same level of SCORE grant incentive funds will be available next year. If it is determined that incentive funding will continue to be granted at the higher amount, bi-annual or quarterly events could be explored for next year. Staff continues to work with Ramsey County to explore other types of eligible incentives in the event the additional cleanup day in August is not desired or if there are funds left over. Some ideas include reusable bags that could be distributed to residents, the purchase of rain barrels that could be offered to residents at a reduced price or compostable lawn bags for residents’ use. Staff would plan to provide an update to the Council after the August clean up event on options for these additional recycling efforts. For this agenda item, we are seeking Council feedback on hosting an August cleanup event as described above.

Public Works Director / City Engineer Brad Fisher, P.E. Principal Project Manager SUBJECT: 2026 PMP Street and Utility Improvements Project – Feasibility Study Review Budgeted Amount: Actual Amount: Funding Source: $3,300,000 $3,089,000 PIR, Special Assessments, (Proposed 2026 CIP) (Feasibility estimate) Utility Funds, RCWD Grant Council Should Consider Council should consider: • Project update related to the feasibility study presentation provided by Bolton & Menk. • Provide direction related to proceeding with the design “alternative” to remove accumulated sediment at five delta locations. • Provide direction related to the Karth Lake Pump System Improvement options. Background The 2025-2029 Capital Improvement Program (CIP), identifies proposed street and utility improvements within the Karth Lake neighborhood area for 2026. The proposed streets include Karth Lake Dr., Pleasant Drive (between south and north cul-de-sacs), Pleasant Dr. (Amble Dr. to south cul-de-sac), Pleasant Circle, Amble Drive (Karth Lake Dr to Lexington Avenue), Karth Lake Circle, and Cummings Park Drive, which includes approximately 133 properties adjacent to the street improvements. The City Council Work Session on February 10, 2025, included discussion of the anticipated scope of work within the project area. At the March 10, 2025 regular Council Meeting, Resolution 2025-025 ordered the preparation of a feasibility report for the 2026 PMP Street and Utility Improvement Project and approved a Professional Services Agreement with Bolton & Menk Page 2 of 3 Discussion The purpose of this agenda item is to share the Draft Feasibility Report, provide a general update of the preliminary scope, resident feedback, budget, and schedule for the project, and seek any direction the Council may wish to provide as staff finalizes the Feasibility Report and recommended special assessment roll. Following direction from City Council, an item will be prepared for the July 14, 2025 regular Council Meeting to accept the Feasibility Report and Order a Public Improvement Hearing anticipated to be held on July 28, 2025. City staff is requesting direction from the City Council related to proceeding with the design “alternative” to remove accumulated sediment at five delta locations and direction for the Karth Lake Pump System Improvement options. For the proposed sediment removal, review in detail within Attachment A Draft Feasibility Report, starting on Page 8, Accumulated Sediment Removal. In summary, this procedure is not a requirement of the City but would be considered maintenance. The bathymetric survey did identify sediment that could be removed. Removal operations would be difficult, costly, and very impactful to the properties needed for access. The design team discussed this procedure with Rice Creek Watershed District for funding opportunities, and they responded they currently do not fund maintenance-type procedures. For the proposed Karth Lake Pump System Improvements, review in detail within Attachment A Draft Feasibility Report, starting on Page 11. Three options are described, Option 2 would be staff’s recommendation with current known funding although staff also recommends exploring Rice Creek Watershed District’s interest in funding capacity with Option 3. If given direction to proceed with either the Karth Lake dredging work and/or the Karth Lake pump system improvements it would be planned to bid the project with these as bid “alternates”. This will allow flexibility to include or remove these work items from the project based on the actual prices bid by the contractor to complete the work. Moving forward with any of the “alternatives” will require a Professional Services Agreement amendment with Bolton & Menk to add the design scope to the project. Within the Feasibility Report (Attachment A) Page 17, Table 3 – Estimated Alternate Projects Costs, the values listed includes overhead which covers engineering services. Budget Impact From the proposed 2026-2030 CIP, the initial budget and cost estimate is summarized in the following table and will be revised as part of the feasibility report. This estimate includes the anticipated costs for engineering design, surveying, and construction administration as a 27% contingency, which is consistent with the PMP process dating back to 2021. Page 3 of 3 * Initial estimate subject to revisions during design phase The $3.1 million project estimate is for BASE improvements only and does NOT include costs for the sediment removal operations or the pump system improvements. Those costs will need to be added above and beyond that budgeted number. The improvements for this project are anticipated to include funding derived from special assessments. The special assessment process must follow the City’s current special assessment policy and maintain compliance with the requirements of Minnesota Statutes 429. A preliminary assessment roll is prepared as part of the feasibility report, and can be reviewed within Attachment A, Appendix C. The policy states that the City will assess fifty percent of the costs associated with bituminous overlay for a typical residential street section and seventy percent of the street project costs for commercial/industrial properties on a unit basis. A general benefit appraisal is in progress and will provide additional information for council to consider when setting the assessment rates on the project. The anticipated special assessments for residential properties are estimated to be $3,880 for mill & overlay areas and $5,850 for full-depth reclamation areas. For reference, the 2022 PMP for full-depth reclamation was $4,958 for properties along Old Snelling and $5,834 for properties in the Arden Oaks neighborhood. The 2024 PMP for full-depth reclamation was $6,045 and for mill & overlay was $2,874.

INTRODUCTION 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 1 I. INTRODUCTION The Arden Hills City Council approved a Professional Services Agreement on March 10, 2025 which ordered the preparation of a Feasibility Report for the 2026 Pavement Management Program (PMP) Street & Utility Improvements project. This report will examine the feasibility of proposed improvements to the roadway and utilities within the 2026 PMP project area. The following streets, trail segments, and the surrounding areas, are proposed for improvements: • Karth Lake Drive from the west cul-de-sac to Pleasant Drive • Pleasant Drive from Amble Drive to the north cul-de-sac • Pleasant Circle from the west cul-de-sac to Lexington Avenue (CSAH 51) • Amble Drive from Karth Lake Drive to Lexington Avenue • Amble Circle from Amble Drive to the north cul-de-sac • Karth Lake Circle from Hamline Avenue (CSAH 50) to the south cul-de-sac • Cummings Park Drive from the west cul-de-sac to Lexington Avenue • Select trail segments on the east side of Cummings Park, connecting to the Lexington Avenue trail See Figure 1 in Appendix A for the proposed project location map. This report reviews the existing conditions in the project area and discusses, in detail, the proposed improvements. These proposed street improvements consist of two construction methods, each determined as a result of deteriorating street pavement conditions and proposed improvements to the watermain, sanitary sewer, and storm sewer infrastructure. The first pavement improvement method is the milling and overlaying of the existing roadway pavement with a new wearing course. The second method is the full depth reclamation of the roadway, a process that pulverizes the existing roadway to create a suitable base for new non-wear course and wear course pavement to be installed. The report also provides preliminary cost estimates for the proposed improvements with financing for the project coming from a combination of special assessments, the City’s general tax levy, and the City’s utility funds. If the City decides to proceed with the proposed street and utility improvements described in this report, it is anticipated construction would begin in 2026 as shown in the detailed project schedule found later in this report. II. BACKGROUND The city’s Capital Improvement Plan (CIP) identifies proposed projects, their associated costs, and funding for a five-year period. The streets evaluated in this report were identified in The City of Arden Hills’s 2025 CIP for construction in the year 2026. The project area is primarily residential with a park area separating the residential properties from the industrial properties surrounding Cummings Park Drive. The project areas were originally constructed as part of five platted developments identified to have been completed primarily in the late 1970’s. The proposed improvements discussed in this report took into consideration the available documents and data related to the project areas, including but not limited to the City of Arden Hills 2040 Comprehensive Plan, record drawings, geotechnical reports, Pavement Condition Index (PCI) ratings, sanitary sewer televising inspections, watermain break and leak history, and field observations conducted by city public works staff. DRAFT Prepared by: Bolton & Menk, Inc. EXISTING CONDITIONS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 2 III. EXISTING CONDITIONS Streets The streets within the proposed project area are all predominantly residential streets with urban street sections consisting of bituminous pavement and B618 or surmountable concrete curb and gutter. The roadways provide a drive lane in each direction and parking along the curb lines. The exception to this is Cummings Park Drive, which consists of a partially median divided urban street section with no parking. The project areas were originally constructed as part of five platted developments identified in the RFP as having been completed primarily between 1977 and 1979 except for the Boston Scientific campus, which was re-platted in 2015. Since the infrastructure’s initial construction, city pavement management records indicate the most recent structural pavement improvement projects include: • Amble Drive – 1994 Reconstruction • Amble Circle, Karth Lake Drive, Pleasant Drive (between the north and south cul-de- sacs), and Pleasant Circle – 2003 Mill & Overlay • Cummings Park Drive and Pleasant Drive (from Amble Drive to the south cul-de-sac) – 2003 Reconstruction • Karth Lake Circle – 2007 Reclamation The project area includes over 130 properties adjacent to the street improvements. Table 1 below shows the existing street widths from face of curb to face of curb, approximate right- of-way widths, and current PCI ratings of the street pavements. Table 1 – Existing Streets Street Name Extents Street Width ROW Width PCI Rating Karth Lake Circle Hamline Avenue to South cul-de-sac 34-ft 60-ft 66 Karth Lake Drive West cul-de-sac to Pleasant Drive 34-ft 60-ft 45 Pleasant Circle West cul-de-sac to Lexington Avenue 34-ft 60-ft 45 Amble Drive Karth Lake Drive to Lexington Avenue 34-ft 60-ft 20 Pleasant Drive Amble Drive to South cul-de-sac 28-ft 60-ft 45 Pleasant Drive South cul-de-sac to North cul-de-sac 34-ft 60-ft 45 Amble Circle Amble Drive to North cul-de-sac 34-ft 60-ft 18 Cummings Park Drive West cul-de-sac to Lexington Avenue 42-ft – 70-ft 75-ft – 100-ft 39 The current PCI ratings for the proposed project streets range from 18 to 45, except for Karth Lake Circle, which is rated 66. The bituminous pavement within the study area exhibits wear and distress due to traffic loading as well as typical weathering effects experienced with aged asphalt pavement. The existing pavement contains surface delamination, transverse cracking, longitudinal cracking, some potholing, and some alligator-type cracking. DRAFT Prepared by: Bolton & Menk, Inc. EXISTING CONDITIONS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 3 Alligator cracking in pavement is an indicator of potential subgrade problems. The street pavements are in generally poor condition and have seen an increased need for maintenance operations which are all indications that the street pavements are in need of varying levels of rehabilitation. Cores with soil borings and a geotechnical evaluation were completed throughout the project area by Braun Intertec and the report is included in Appendix F. The existing bituminous pavement thickness generally ranges from 3.5 to 5.5 inches with a few select areas of thicker pavement, up to 11 inches. The existing aggregate base thickness generally ranges from 5 to 8 inches, with a few areas of thicker aggregate base and a couple of locations of thinner aggregate base. The areas with thinner aggregate base may require additional stabilization and will need to be identified during construction. Existing subgrade soils found beneath the aggregate base are predominantly a mixture of clayey and sandy soils, with low organic content indicating the material is suitable for reuse onsite during utility work. Sanitary Sewer City records show the sanitary sewer system was installed during the various phases of development. The project area is served primarily by polyvinyl chloride (PVC) pipe sanitary sewer mains. The gravity sanitary sewer is part of sewer district M059, with the sewer along Cummings Park Drive being part of sewer district M051, and is predominately 8-inch diameter. The comprehensive sewer plan does not identify changes in pipe diameter within the project area. The existing condition of the sanitary sewer system was documented by videotaping of the sewer main. City Public Works staff completed this televised documentation in the spring of 2025. The televising revealed that the pipes were in generally good condition, with approximately four locations that were identified as needing rehabilitation or repairs. A project questionnaire to property owners indicated that some properties are experiencing sewer service issues but they primarily appear to be issues related to the private service line itself and not the connection to the main. Some of the defects found in the sanitary sewer were pipe deflections, root intrusions, gasket issues, and groundwater infiltration at joints. The groundwater infiltration adds to the volume of wastewater being treated and subsequently the wastewater treatment costs. Sags and offset joints can interfere with the flow of sewage, creating a higher maintenance cost. The project area also includes sanitary Lift Station 13, located at the northwest corner of Pleasant Drive and Karth Lake Drive. The lift station pumps to a 6-inch DIP forcemain which runs west and outlets to the gravity sanitary sewer system on the west side of Hamline Avenue, just south of Karth Lake Circle. Lift Station 13 was last rehabilitated in 2023 and is in excellent condition and the forcemain has no history of breaks. Watermain City records indicate that existing watermain within the project area is primarily Ductile Iron Pipe (DIP), varying in size between 6-inches and 8-inches, with 12-inch diameter pipe located on Cummings Park Drive. The watermain system runs throughout the project area and connects to a looped system at most roadway connections. Additionally, there is a watermain loop within utility easements that serves a few properties north of Karth Lake Drive, along County Road 96. This looped watermain runs approximately under the south curb line of County Road 96 and has had a history of some breaks. These breaks cause impacts to the county road which adds additional coordination and expense to the repairs. DRAFT Prepared by: Bolton & Menk, Inc. EXISTING CONDITIONS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 4 Beyond the County Road 96 watermain, a review of the City’s watermain break historical records did not identify any further breaks or leaks in the project area other than isolated leaky valves, damaged valves, damaged hydrants, and bent valve boxes. This indicates the majority of the watermain pipes are still in good operating condition. City public works staff identified the need for an additional hydrant along Amble Drive and also identified a number of curb stop boxes that are either buried or sticking out of the ground. The comprehensive water plan does not identify changes in pipe diameter within the project area. Storm Sewer The existing drainage system has limited storm sewer with outlets into Karth Lake and storm ponds located along Lexington Avenue and CSAH 96. City records indicate that the existing storm sewer within the project area is primarily comprised of Reinforced Concrete Pipe (RCP). The existing drainage pattern within the project area is generally from the exterior project limits in towards Karth Lake. Some of the existing storm outlet aprons are partially or fully submerged within Karth Lake. The City’s Public Works staff completed inspections of the existing storm sewer and found these pipes to be in good condition, with minor manhole repairs and replacement of existing castings as necessary. Storm sewer televising identified approximately eight locations with joint separation, cracking, and/or offset joints, that will need to be addressed. Stormwater Management Existing grit chambers are located in all storm systems prior to the storm outlets, except the Karth Lake Circle outlet, in an effort to collect sediment and debris before discharging into Karth Lake. A significant amount of overland drainage from the industrial/commercial properties to the south enters Karth Lake along the southeast bank. A previous project was completed in this area to reduce erosion by stabilizing the slope and providing for a culvert crossing under the trails south of Karth Lake. There are a total of five storm water outlet locations included in this project scope within Karth Lake which have accumulated sediment over time (there are six total outlet locations into the lake). These delta locations have collected sediment over time that entered the lake from the storm sewer system. Karth Lake Karth Lake is a natural occurring lake and is a Public Water as identified by the Minnesota Department of Natural Resources (MnDNR) on their Public Waters Inventory (PWI). There is no emergency overflow for the lake where water can escape to during high water levels without causing flooding conditions. The 100-year floodplain elevation is 938.19 (NAVD 88). As a result, the City installed and operates a manually deployed pump and forcemain system to manage the lake level. The pumped outlet consists of a pump system with a sump pump mounted on a floating raft that pumps through a 6-inch forcemain to the southwest where it outlets in the city storm sewer system at the north side of the Cummings Park Drive cul- de-sac. This system was installed in the early 2000’s and is permitted through the MnDNR to maintain lake levels between an elevation of 934.0 and 936.0. Trails Existing trails exist within Cummings Park and along the south side of Cummings Park Drive. City staff identified trail segments within Cummings Park, extending west from Lexington Avenue, and along the south side of Cummings Park Drive on the east end, which are in particularly poor condition. These trails are constructed of bituminous pavement and are DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 5 generally in a deteriorated condition with significant surface delamination and cracking throughout. Other surrounding trails have received more recent maintenance operations are in acceptable to good conditions. The existing trail back to the Karth Lake pump station is only gravel and contributes to erosion in the area. Cores with shallow borings and a geotechnical evaluation were completed throughout the project area by Braun Intertec and the report is included in Appendix F. The existing bituminous trail thickness is generally around 2-inches with the existing aggregate base thickness generally around 2-inches as well. Retaining Wall An existing retaining wall surrounds the Karth Lake pump station and electrical box. It is a three-tiered timber retaining wall that is in poor condition and contributes to erosion along the steep bank slopes into Karth Lake. IV. PROPOSED IMPROVEMENTS Streets There are two street pavement rehabilitation methods proposed for this project that are based on roadway age, surface deterioration, PCI ratings, and subgrade soils. Streets will be rehabilitated with either a full depth reclamation or mill and overlay based on recommendations from the geotechnical report. Full depth reclamation is a process that pulverizes the existing roadway pavement and mixes it with the existing underlying aggregate material to create a new suitable aggregate base material. The reclaim material is graded and recompacted for the proposed roadway with excess material being hauled away and 4-inches of new bituminous pavement installed in two lifts. A mill and overlay is a process that grinds off the top layer of bituminous pavement and approximately 2-inches of new wear course bituminous pavement is installed over the remaining base bituminous pavement. Both rehabilitation methods will include spot curb and gutter replacements, select base pavement repairs and/or subgrade corrections, and casting or valve box adjustments to the new pavement grade. The spot curb and gutter replacements will be utilized to address sunken or severely damaged curb throughout the project area that inhibits proper drainage. No driveway work is proposed, except as necessitated by spot curb replacements or utility work. All disturbed boulevard areas will be restored with 5-inches of topsoil and new sod or seed and blanket. Select street signs and street name blades are identified for replacement based on a city inventory completed in the summer of 2025. Based on the observed weathering and deterioration found in the pavement cores and soil borings, a 2-inch to 2.5-inch mill and overlay is proposed for the following street: • Karth Lake Circle from Hamline Avenue (CSAH 50) to the south cul-de-sac Based on the observed weathering and deterioration found in the pavement cores and soil borings, an 8-inch to 10-inch full-depth reclamation is proposed for the following streets: • Karth Lake Drive from the west cul-de-sac to Pleasant Drive • Pleasant Drive from Amble Drive to the north cul-de-sac • Pleasant Circle from the west cul-de-sac to Lexington Avenue (CSAH 51) • Amble Drive from Karth Lake Drive to Lexington Avenue • Amble Circle from Amble Drive to the north cul-de-sac • Cummings Park Drive from the west cul-de-sac to Lexington Avenue DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 6 In areas of thinner pavement section, stockpiling of the reclaim to allow for approximately 2-inches of additional subgrade excavation and replacement of the reclaim material to ensure a 6-inch reclaim aggregate base section beneath the bituminous pavement may be necessary. However, the specific limits of these potential areas will not be known until they are under construction for evaluation and will need to be addressed during construction operations, if necessary. See Figure 1 in Appendix A for the proposed project layout identifying the limits of each rehabilitation method. Sanitary Sewer Based on the existing sewer pipe age, material type, and televising results, the existing sanitary sewer was found to be in generally good condition. There are a few select defects that are proposed to be rehabilitated as part of the project by means of Cured In Place Pipe (CIPP) sewer lining, sewer pipe grouting, and spot open cut pipe replacement. Most of the proposed sanitary rehabilitation methods are trenchless which will not disturb the above ground infrastructure as all access to the sewer is through existing manholes along the pipe and all services or laterals will be reopened robotically from within the pipe. All sanitary sewer manhole castings within the project areas will be replaced and installed to final grade to provide a smooth/drivable street surface in conjunction with the street resurfacing portion of the project. This work will also include the replacement of all concrete adjustment rings and the installation of an external chimney seal for each applicable manhole structure to reduce inflow of stormwater into the sanitary sewer system. Additionally, “painted on” internal chimney seals will be installed to mitigate deterioration of the concrete adjusting rings and mortar to reduce the need for long term maintenance. No work on structures outside of the street pavement is proposed, unless otherwise identified on the identified utility improvements figure or those identified to be trenchless improvements. City staff completed an inventory of the height of concrete adjusting rings on each sanitary manhole throughout the project area. Those manhole structures identified to have 16- inches of rings or more will be reconstructed, which is the process of removing the top cone section, adding a 1-ft barrel section to the structure, then replacing the cone section. See Figure 5 and Figure 6 in Appendix A for the proposed utility improvements. Watermain Based on the existing watermain pipe age and size, the existing watermain was found to be in generally good condition. Proposed watermain improvements include relocation of the watermain on south side of CSAH 96, approximately under the existing curb line. The existing will be abandoned in place and the new watermain will be located approximately 20-ft south, to maintain a 10-ft separation from the existing sanitary sewer that runs parallel. The watermain will be replaced in-kind with 6-inch DIP. All water service lines connected to this segment of watermain are proposed for replacement from the watermain to the property line with new 1-inch diameter copper pipe to individual residences. Curb stops and boxes will be installed at the ROW where the new service pipe connects to the existing service pipe. Constructability will be further evaluated during final design to mitigate impacts to adjacent retaining walls. This may necessitate connecting to the existing water service prior to the retaining walls and potentially a second curb stop on the same service line. Beyond this segment of watermain replacement, water system improvements will include addition of a new hydrant, addition of a new gate valve, replacement of select hydrants, replacement of select gate valves and boxes, and adjusting the remaining gate valve boxes DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 7 within the project pavement areas to final grade to provide a smooth/drivable street surface in conjunction with the street resurfacing portion of the project. Some damaged valve box tops may require replacement. Hydrant replacements will include the associated gate valve and lead. Existing curb stop boxes identified to be buried or significantly sticking up above the surrounding ground level will be adjusted to the proper ground level. A few curb stops that were not located by city staff will have exploratory excavations completed as part of the project in an effort to locate them or replace them further upstream on the service line to be accessible. See Figure 5 and Figure 6 in Appendix A for the proposed utility improvements. Storm Sewer Based on the existing storm sewer age, size, and performance, the existing storm sewer was found to be in generally good condition. Storm sewer improvements will include rehabilitations at select locations including CIPP lining, minor pipe replacement, select structure replacements, and riprap rehabilitations at select outlet locations. Some of the work identified will be taking place outside of the roadway area in easements that may necessitate tree removal and restoration of temporary access impacts, including private landscaping facilities in some areas. Stormwater quality improvements will also be implemented to help remove sediments and pollutant loads from entering Karth Lake. This will include the replacement of the last storm sewer structure in the street prior to its outfall into Karth Lake, where an existing grit chamber does not exist. This structure will be replaced with a new structure that includes a sump and SAFL Baffle to capture sediment from continuing downstream. This will allow city maintenance staff to easily access the structure and vac out accumulated sediment. Beyond the work identified above, the remaining storm sewer manhole castings within the pavement of the project areas will be adjusted to final grade to provide a smooth/drivable street surface in conjunction with the street resurfacing portion of the project. Some damaged castings may require replacement (assuming 50%). This work will include the replacement of all concrete adjustment rings for each applicable manhole structure within the pavement limits. Additionally, “painted on” internal chimney seals will be installed to mitigate deterioration of the concrete adjusting rings and mortar to reduce the need for long term maintenance. Catch basins within the existing concrete curb and gutter will not be adjusted, unless otherwise identified for structure replacement or curb replacement surrounding the structure. See Figure 5 and Figure 6 in Appendix A for the proposed utility improvements. 1. Risk Assessment of Submerged Culverts in Karth Lake A bathymetric survey was performed in April 2025 to assess the sediment load near the five submerged outlets to Karth Lake. The survey found some organic sediment was accumulating near the outlets, but the majority of sediment is being pushed out further into the lake and forming sediment deltas. These deltas do not negatively affect the performance of the submerged inlets. There was a noticeable ‘hard-bottom’ at each outlet location assumed to be a mix of gravel and rock erosion delivered by the storm outlets. However, the limits of the sediment deltas relative to the ‘hard- bottom’ of Karth Lake’s natural lakebed is difficult to delineate. The outlets likely deliver suspended solids and particulates to Karth Lake without creating a clogging issue. Each inlet is clear of sediment and debris and has a free outfall condition. The four of the five outlet pipes to Karth Lake are submerged and fully below the DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 8 normal water level. Submerged pipes that outlet stormwater into static, or landlocked, water bodies typically build up sediment due to standing water. The outlets into Karth Lake were unobstructed likely due to the following: • Sufficient Flow Rate and Velocity - MnDOT recommends RCP stormwater pipes are designed to have a full flow velocity of at least 3 feet per second. This velocity is typically found to ‘self-clean’ stormwater pipes. Sand and small suspended solids are unable to drop out of the stormwater flow. • Depth of Receiving Water - Karth Lake has sufficient depth and volume for water to freely exit each outfall. No underwater deltas have formed creating a hydraulic jump for water and sediment to backflow into the storm outfalls. Additional risks associated with submerged pipes include: • Freeze/Thaw Cycles – Submerged pipes are subject to increased risk of pitting and cracking due to expanding ice in winter months. Throughout the lifespan of the pipe the structural integrity is much lower than a non-submerged pipe. Many factors can contribute to how fast a submerged pipe cracks including water depth, bedding material, pipe diameter, and weather. Ice build-up is another risk that could lead to upstream flooding particularly in snow melt events. If an outlet is completely blocked with ice, snow melt will be unable to discharge from the drainage system and present surface flooding issues. The amount of freezing weather in any winter season will drive the depth of ice in Karth Lake. The deepest outlets are approximately five feet under the ordinary high water level in Karth Lake and are unlikely to fully freeze. The shallower outlets are more susceptible to being encapsulated by fully freezing conditions but the weather will play a factor in the effect freeze/thaw cycles have on backups to the system and long-term effects. • Sediment Build-Up – No sediment build-up is occurring at these submerged outlets, but the risk is higher than non-submerged outlets. It is possible that in a future snowmelt event or large rain event that transports an unusually high amount of suspended solids and organic matter will clog and fill the pipe. This may create flooding upstream of the clogged outlet and present surface flooding issues. That being said, these observations may be due to the fact that the majority of the existing outlets into the lake have existing grit chambers that are properly performing in general to minimize sediment transport. The fact that there are additional proposed improvements to add or improve sediment capture devices prior to outletting stormwater at remaining locations should help alleviate this concern further. No improvements to the storm outlets are proposed and it is recommended to complete regular condition inspections on each apron to address repairs/replacements on an as-needed basis. Additional evaluation can be completed if proactive improvements are desired which would likely include adding an inline storm structure and flattening the outlet apron to be above the ordinary high water level. Stormwater Management 1. Accumulated Sediment Removal A bathymetric survey was performed in April 2025 to assess the sediment load near the five outlets into Karth Lake. The survey found some organic sediment was DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 9 accumulating near the outlets, but the majority of sediment is being pushed out further into the lake and forming sediment deltas. There was a noticeable ‘hard- bottom’ at each outlet location assumed to be a mix of gravel and rock erosion delivered by the storm outlets. However, the limits of the sediment deltas relative to the ‘hard-bottom’ of Karth Lake’s natural lakebed is difficult to delineate and therefore the total accumulated sediment at each delta is not accurately quantified. Braun Intertec completed sediment sampling from the five outlet locations within Karth Lake to characterize the in-place sediment (future dredge material). These sediment samples were tested and evaluated in accordance with the Minnesota Pollution Control Agency’s (MPCA) current best management practice for Managing Dredged Materials. Sediments observed during the completion of the borings consisted primarily of dark brown to black silty sand with organic materials noted at four of the locations. Based on analytical results from the sampling and testing, sediment from location O-1 falls within the management Level 1 characteristic, sediment from locations O-2, O-4, and O-5 falls within the management Level 2 characteristic, and sediment from location O-3 falls within the management Level 3 characteristic. Therefore, sediment removal operation will require segregation of material from each location, or it all will be required to be treated at the most restrictive sediment management level. Unlike stormwater ponds, it is not possible to completely drain Karth Lake to perform sediment removal operations. Therefore, specialty construction methods will be required to conduct the operations. It is assumed that the accumulated sediment is generally contained within an approximate 100-foot radius of the outlet location. Easements exist over each of the four storm sewer outlets that run between residential houses and the fifth outlet comes from within Cummings Park, which is property owned by the City. However, the grades down to the lake, trees, and private landscaping features may make access to each location difficult or infeasible within the confines of the existing easements, especially as it relates to trucking out the excavated sediment. Three options for sediment removal operations were considered as part of this report but additional data collection and evaluation would be required during final design to verify feasibility of the selected option at each location, if proposed for inclusion as part of the project. • Cofferdams and dewatering – This operation involves the installation of temporary steel sheet piling around the anticipated sediment delta to create a cofferdam at each outlet location. This would then allow for the outlet locations to be dewatered utilizing pumps to expose the lake bottom. The accumulated sediment would then be removed by means of an excavator and hauled off in dump trucks. Dump truck access to the water within the existing easements appears unlikely due to existing grades. Therefore, the excavator will likely need to stockpile the material on the bank of the lake and then have it transported up to dump trucks at the street via skid steers or similar small equipment that can better traverse the landscape. Each easement will require tree removal and most will require removal of private landscaping features to accommodate access. At the conclusion of sediment removal operations, the steel sheet piling is removed and impacted areas are restored. • Hydraulic dredging – This operation involves the removal of accumulated sediment using hydraulic forces from a boat/barge to suction up the materials. This is most commonly used to maintain channel depths for marine DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 10 travel but has a number of other applications, including targeted sediment removal. This operation is less exact as verification of where the material is removed from and the exact volume is not accurately defined and the boat will not be able to get into shallow waters. The benefit to this operation is that only a singular access point to the lake is required and it is less impactful. However, to the best of our knowledge, there is no existing access location that can accommodate a boat launch which means one would need to be temporarily constructed. It is anticipated that this access would come from the Cummings Park area and would require significant tree removal and re- grading to accommodate. • Vacuum trailer – This operation involves sucking out accumulated sediment utilizing suction. Similar to a vacuum truck, a vacuum trailer is a smaller piece of equipment that is hitch mounted to a pickup truck which allows for it to be more accessible. This operation is the least exact as verification of the material removed and quantity is not accurately defined. However, it will certainly provide benefit in removing accumulated sediment to the extent practical. Pickup truck and trailer access to the water is required and may require temporary improvements within easements to accommodate. Each easement will require tree removal and most will require removal of private landscaping features to accommodate access. At the conclusion of sediment removal operations, impacted areas are restored. Consideration was made to performing sediment removal operations in the winter, when the lake is frozen to allow for easier access to the various outlet locations. However, a lack of safe means to access the sediment beneath the ice for removal limited the considerations for this option. Based on the options evaluated relative to the City’s stated goal for sediment removal, costs were evaluated for the cofferdams and dewatering option and included as a design alternate to keep costs separated for consideration on whether or not to incorporate with the project. If the accumulated sediment is not removed as part of the project, there are limited risks in the short term as the storage capacity is so large on a lake of this size, however, its removal provides benefit to the lake’s water quality. With other improvements proposed as part of the project, sediment making its way to the lake via the storm sewer system should be further minimized. The remaining major contributors to sediment accumulation in the lake after the project includes erosion from the banks of the lake and organic matter falling from trees around the lake (assuming the sediment capture devices incorporated into the storm sewer system are regularly maintained). See Figure 1 in Appendix A for the proposed project layout identifying the limits of each proposed sediment removal location in Karth Lake. The sediment sampling data and associated report completed by Braun Intertec is included in Appendix F. 2. Stormwater Pond BMP – Phase 2 Steep slopes from the industrial/commercial properties to the south towards Karth Lake to the north have caused major erosion and sediment pollution into the southern end of Karth Lake. A study was performed by Ulteig Engineers, Inc. in 2020 to explore a solution. The “Phase 1” project solutions included realigning the existing eroded swale to a zig-zag pattern to reduce slope and establishing a vegetated bottom and sides to minimize soil disturbance and erosion. As part of that study, a “Phase 2” improvement to treat the runoff was identified. DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 11 The Phase 2 improvement is proposed for design and construction as part of the 2026 PMP project and includes installation of a stormwater BMP to treat stormwater runoff from the Boston Scientific Campus and Cummings Park before it reaches Karth Lake. The stormwater BMP retention pond would be located at the southeast side of the lake, where the Phase 1 improvement outlets under the trail. No water from the site is currently treated causing pollutant concerns for Karth Lake and Valentine Lake, which receives the pumped flow leaving Karth Lake. Valentine Lake is impaired for chloride and nutrients and will benefit from any water quality benefits to Karth Lake. Two BMP options, a wet pond and an infiltration basin, were explored to treat this stormwater runoff. With the proximity to Karth Lake, groundwater elevation will likely be within 3 feet of the final infiltration depth and make infiltration infeasible. A wet pond is likely the best option for this site. This location receives approximately 11 acres of drainage area, with 5.5 acres of that being impervious. According to Rice Creek Watershed Districts rule of 1.1 inches of runoff over the contributing impervious area, the water quality volume that would be required if the entire area was developed or reconstructed today is listed in the table below: Storage Aspirations Stage Volume Required (Ac-Ft) Volume (Cu-Ft) Dead Pool 0.452 19674 Live/WQV 0.499 21746 Total 0.951 41420 In order to accommodate that volume of pond, it is estimated that the pond itself will be approximately ¼ acre in size and its impacts will extend beyond that to tie into existing grades and for associated storm sewer installations. However, there isn’t sufficient space between the Phase 1 outlet and Karth Lake to accommodate that area of pond. Therefore, it is proposed to design the pond to the maximum size feasible with the space available. Based on the scale of the proposed stormwater pond and the proposed location, it should be noted that significant tree removals will be necessary to accommodate its construction. This improvement was originally identified as part of the Karth Lake Management Action Plan. See Figure 1 in Appendix A for the proposed stormwater BMP retention pond location. Karth Lake Pump System The Karth Lake Improvement District (KLID) consists of Karth Lake’s lakefront property owners. The KLID modeled the pump operations and has made a recommendation to revise operations to limit the lake to a 6-inch bounce level between 935.0 and 935.5 to help alleviate shoreline erosion by allowing vegetative growth to maintain and stabilize the shoreline. Three options to implement this improvement to the pump system were evaluated as part of this feasibility report. The KLID had previously conducted their own research and coordinated with Joy Loughry, Water Monitoring and Surveys Unit Supervisor for the MnDNR which were all considered in development of these options. Option 1 Maintain the existing ~350 GPM deployable pump and install a cloud-connected water logging device to more accurately determine when to deploy and remove the pump from Karth Lake. DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 12 It is recommended to utilize an In-Situ Vulink with a Rugged Troll 200 water logging device. This device will sit in an anchored Rugged Buoy near the deployable pump location in Karth Lake. The Rugged Troll 200 Data Logger is capable of monitoring surface water and will allow the city to monitor the water level of Karth Lake from an online application. The batteries included with the In-Situ Vulink will power the logger with a manufacturer estimated 10- year lifespan. a. Approximate Construction Cost: $10,000 Annual inspections of the system are recommended to keep the system operating as it should but battery replacement and an annual telemetry subscription are the only anticipated ongoing maintenance/costs over the life of the system. Option 2 Install a new 48-inch diameter, 6-foot deep concrete manhole structure to place the existing deployable pump in. Install a submerged 18-inch RCP skimmer pipe below the normal lake level to direct lake water from Karth Lake to the pump manhole while also mitigating the influences of wave action and wind on the water logging device. This installation to connect the system to the lake will require specialty installation measures to allow for installation of the culvert within the lake footprint, such as temporary steel sheet piling or similar. Install water monitoring logger and create automated on/off water elevation triggers. The existing ~350 GPM pump will be deployed from spring to fall and will operate automatically to maintain desired water levels. The pump will connect from the new location to the existing 6-inch forcemain that outlets to the gravity storm network on Cummings Park Drive. It is recommended to use the OTT PLS 500 Pressure Level Sensor. This water logging device will be housed in the manhole structure or stilling well. The OTT PLS 500 will be paired with a Sutron SatLink3, or approved equal, to log and transmit data. Power to the system will be supplied with 12V DC power from a solar panel. Electrical components needed include a 33 AH battery, 20W solar panel, solar regulator, equipment enclosure, mounting, and orifice line conduit. a. Approximate Construction Cost: $80,000 Annual inspections of the system are recommended to keep the system operating as it should but minor part replacements and annual telemetry subscription are the only anticipated ongoing maintenance/costs over the life of the system. Option 3 Install a new permanent lift station that includes an 18-inch skimmer pipe installed below the normal water level for Karth Lake, that directs water to a lift station vault with a permanent stormwater pump and potentially upgraded forcemain. This installation to connect the system to the lake will require specialty installation measures to allow for installation of the culvert within the lake footprint, such as temporary steel sheet piling or similar. This upgrade will also include a cloud connected water logging device and will likely require an upgraded electrical service to the lift station to provide adequate power for the proposed pump. To efficiently maintain a bounce of 0.5 feet in Karth Lake a new lift station was preliminarily sized with the limited information available to understand associated costs. The existing pumped flow rate of ~350 GPM was found to be inefficient and require pumping for extended periods of time to return Karth Lake to the ordinary high water surface elevation. This option includes upsizing the existing pump to quickly return Karth Lake to pre-rainfall levels and maintain a more consistent bounce. When installing a new pump, the existing 6- DRAFT Prepared by: Bolton & Menk, Inc. PROPOSED IMPROVEMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 13 inch force main will likely need to be upsized to handle the increased flow rate, but additional evaluation will be required based on the selected improvements. The electrical service will also need to be upgraded to provide sufficient power to the pump. The pump will be placed in a concrete vault along with an automated water surface float. This float will trigger the pump on and off according to preset water levels. This is the most robust and expensive of the options but provides the greatest benefit to the residents of Karth Lake and the city. b. Approximate Construction Cost: $500,000+ Annual inspections of the system will be required and ongoing maintenance/costs will be similar to other lift stations throughout the city. It is assumed that if this option were selected, City Public Works staff would provide information on components utilized on existing lift stations throughout the city to provide seamless integration and operation for staff. If selected, a more thorough analysis of the existing system, required pump size, required electric needs, and whether the forcemain requires replacement or not will be required. Understanding long lead times for control panels, it should be noted that this option will likely take in the neighborhood of 18 months to construct, depending on final selections. Conclusions While Option 3 is the best option for monitoring and operation, it also comes with significantly higher construction costs than the other options. Options 1 and 2 both provide cost-effective improvements that can be implemented with relative ease. All three options can be further customized to meet the city’s needs and final costs will depend on the options selected, including preference for cellular or satellite telemetry. While the city’s current operations meet the requirements of their permit, it is difficult for the limited city resources to always stay apprised of the current lake conditions and needs. Therefore, improvements could be made to alleviate staff time allocated to monitoring the lake elevation and/or pump deployment/removal and free that time up for other important city services. And improvements would help to meet the request of the KLID board to better manage the lake elevations to a more restrictive level than is required under the city’s permit requirements. The City and the KLID board should have discussions on potential cost sharing options and what improvement option best fits with the goals of each organization. The selected option will be further evaluated and incorporated into the final design of the project. Costs for these improvements are not included in the base project costs but are separated out as options for the City’s consideration. Trails Given the thin existing trail section, reclamation of the trails is not recommended. The proposed trail improvements for select trail segments in Cummings Park include removal of the existing bituminous pavement (where applicable), supplementing the existing remaining gravel as needed to construct the proper aggregate base section, and repaving the trails with new bituminous on the aggregate base materials. For the identified segment of existing trail that is only gravel, it will be top-dressed with additional reclaim material as necessary, graded, and paved to provide access to the Karth Lake pump station. The trail replacement limits were extended west to the Cummings Park entrance due to damage anticipated with construction access to the Karth Lake pump station and the proposed new stormwater pond. The trails are proposed to be replaced, in kind, matching the existing trail alignments, widths, and elevations except where improvements make sense to improve drainage patterns. Due to the existing site topography, some segments of these existing trails appear DRAFT Prepared by: Bolton & Menk, Inc. STAKEHOLDER COORDINATION 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 14 to be quite steep and may not be feasible to improve to strict compliance with Americans with Disabilities Act (ADA) requirements. Additionally, ADA improvements will be implemented at two pedestrian ramp locations on the west end of Cummings Park Drive. The trail coming from the north is proposed to be realigned west to provide for a shorter and more perpendicular pedestrian crossing. The older trail pavement along the south side of Cummings Park Drive will also be replaced as part of the project (the first approximately 500-feet from Lexington Avenue). Finally, the trail segment along the south side of County Road 96 will also require replacement due to impacts from the proposed watermain work in the area. See Figure 1 in Appendix A for the proposed project layout identifying the trails to be rehabilitated and the locations of ADA pedestrian ramp improvements. Retaining Walls In coordination with the trail improvements, the existing three-tiered timber retaining wall near the Karth Lake pump station is proposed for replacement. It will be replaced with a modular block retaining wall and designed to mitigate undermining and erosion directly into Karth Lake. The constructability of this retaining wall will be further evaluated during final design to determine impacts to the existing electric service box behind the existing wall. Depending on options, the electric service box may necessitate relocation. See Figure 6 in Appendix A for the proposed retaining wall replacement. V. STAKEHOLDER COORDINATION Private Utilities A private utility coordination meeting will be held with private utility companies that have facilities within the project area to understand the presence of existing overhead or underground facilities and plans for infrastructure upgrades or necessary relocations during the final design phase of the project. Based on the scope of this project primarily being a rehabilitation project, major conflicts are not anticipated but will be verified during the final design process. During coordination with these companies, the potential for coordinating fiber installations to provide home service will be discussed to minimize long-term impacts, if there are plans to provide this service. Public Involvement An online survey, posted from March to April 25, 2025, provided residents and property owners with an opportunity to provide feedback on the proposed improvements and identify information on the existing conditions within the project area. The mailing area included all properties adjacent to the proposed street improvements, as well as all properties along Karth Lake as part of the Karth Lake Improvement District (KLID) due to the considerations given to work in/along the lake. The feedback received included a lot of property specific information, but several common themes were also identified from the completed surveys. The common themes include concerns over impacts to irrigation systems, dog fences, private electric wiring, and landscaping, concerns regarding erosion over Cummings Park trails, concerns over street patches due to private sewer repairs, concerns over how the project will be assessed, existing drainage issues, interest in attracting telecom companies to install fiber internet, interest in adding street lighting, support for sediment capture BMP’s prior to it entering the lake and general water quality improvements, and support for the KLID board’s request for lake level monitoring/pumping improvements including to the associated retaining wall, hose and control panel. The DRAFT Prepared by: Bolton & Menk, Inc. RIGHT-OF-WAY, EASEMENTS, AND PERMITS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 15 general consensus over the condition of the existing roadway pavement throughout the project area is that it is deteriorated to fair, generally showing public support for the proposed street improvements. The results of this survey were considered during the development of this feasibility report and items within the scope of the project were incorporated to address the feedback received. It should be noted that to align with city policy, potential damage to irrigation systems will be repaired as part of the project by the selected contractor, however, potential damage to dog fences is the responsibility of the homeowner to repair. A summary of the responses received from the resident survey can be found in Appendix E, with personal information redacted. Another opportunity for public involvement will be at a public open house, tentatively scheduled for November of 2025, to share the proposed project design. Feedback from the open house will be considered and incorporated into the final design as directed by city staff. A final public informational meeting will be held after the final design is better defined but prior to construction of the project. RCWD Grant Opportunities RCWD indicated they are supportive of the proposed Karth Lake pumping improvements to implement lake level monitoring and potential automation of the pump system. It was indicated that they would be a potential funding partner depending on what improvements are proposed for implementation and what the associated financial impact is associated with the improvements. City staff will approach RCWD again after receiving direction on the Karth Lake pumping improvements to continue discussions on potential financial support. Any potential financial support for these improvements would not be through a grant program and would be through other funding mechanisms to help support the goals of the watershed. Their support stems from a desire to help stabilize the shoreline level at 935.0 to 935.5 (as opposed to 934.0 to 936.0) which would help alleviate shoreline erosion by allowing vegetative growth to maintain and stabilize the shoreline. Existing RCWD grants are available this fiscal year and there are three improvements identified with this project that were confirmed to be eligible for application through these programs. The RCWD’s Stormwater Management Grant is a 50/50 cost share with up to a $100k grant award, in total. Applications are due around mid-December with awards anticipated in Spring of 2026. This application timeline aligns well with the proposed schedule for the 2026 PMP project. The incorporation of new sump storm structures with SAFL Baffles to help trap sediment from continuing downstream and into Karth Lake is one eligible improvement for this grant. The other improvement would be the construction of a new stormwater pond to treat stormwater before entering Karth Lake (a continuation of the previously completed “Phase 1” slope stabilization project). The RCWD’s Water Quality Grant opens at the beginning of the year and is available until funds run out. Given the proposed schedule for the 2026 PMP project, this may or may not be available when plans are finalized and ready for submission. If available, the replacement of the retaining wall near the Karth Lake pump station would be eligible for this grant to alleviate erosion coming from the failing wall. VI. RIGHT-OF-WAY, EASEMENTS, AND PERMITS All work on the project is anticipated to take place within existing city right-of-way or easements. However, after completing final design, it is possible that temporary easements or right-of-entries DRAFT Prepared by: Bolton & Menk, Inc. RIGHT-OF-WAY, EASEMENTS, AND PERMITS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 16 may be necessary to construct the project. For various work items, minor encroachment onto private property may be beneficial in order to achieve a better overall quality of work. It is assumed that project staff will discuss these with property owners and obtain right-of-entries on a case-by-case basis. These items include water service and curb box installation, sanitary service installation, retaining wall installation, and driveway connections. This will be evaluated in detail towards the end of the final design process to identify any temporary easement or right-of-entry needs, particularly as it relates to the work beyond the roadways. The project area is within the jurisdiction of the Rice Creek Watershed District (RCWD) and therefore requires compliance with their rules and regulations. A meeting was held with RCWD staff on May 29th, 2025 to understand how their rules and regulations apply to the proposed project. The project falls under the Public Linear Project category for Stormwater Management rules and therefore stormwater management is not required unless the project disturbs one acre or more of new or reconstructed impervious surface’s underlying native soils. Being that the project is primarily a rehabilitation project and plans to leave the existing base pavement, aggregate base, and/or reclamation material in place, the disturbance to underlying native soils where impervious surface is proposed is currently calculated to be under the one-acre threshold and stormwater management permitting is not anticipated. An Erosion & Sediment Control Plan permit will be required through the RCWD associated with the project’s erosion control plan. A wetland delineation was conducted during the spring of 2025 to identify the wetlands surrounding the proposed improvements and submitted to the appropriate agencies for concurrence of wetland types and boundaries. Permitting associated with anticipated wetland impacts will be submitted to the appropriate agencies for approval at the conclusion of final design and is expected to meet the conditions for a temporary impact permit associated with the Wetland Conservation Act (WCA) requirements. Karth Lake is identified as a Public Water and therefore additional permitting is required for the dewatering of Karth Lake associated with the accumulated sediment removal work, if approved. This will require, at a minimum, a Minnesota Department of Natural Resources (MnDNR) Public Waters Work Permit. Additionally, existing, adjacent wetlands have potential additional associated permitting needs related to the accumulated sediment removal work, if approved. It is recommended the project’s final design scope be modified to complete the necessary topographic surveys and wetland delineations to move forward with the proposed backyard storm sewer improvement work, if approved for final design. • MPCA Construction Stormwater Permit • MDH Public Watermain Plan Review Permit • Ramsey County ROW Permit • RCWD Erosion & Sediment Control Permit (Rule D) • RCWD Floodplain Alteration Permit (Rule E) • RCWD Appropriation of Public Waters (Rule J) • WCA Permits & RCWD Wetland Alteration (Rule F) • MnDNR Public Waters Work Permit o Including confirmation of any adjustments to the city’s existing permit for pumping operations due to adjusting the OHWL DRAFT Prepared by: Bolton & Menk, Inc. ESTIMATED COSTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 17 VII. ESTIMATED COSTS Detailed estimates of probable construction costs have been prepared for the improvements described in this report and are included in Appendix B. All costs are based on anticipated unit prices for the 2026 construction season based on actual bid prices for similar projects. Actual costs will be determined through competitive bids following the final design for the project. All estimated costs also include a 10% contingency and 27% overhead allowance for legal, engineering, administrative, and finance costs. Table 2 below contains a summary of the estimated total project costs for the recommended base project improvements, inclusive of construction costs, contingency, and overhead allowance. One design alternate was evaluated as part of the preliminary design for the potential removal of accumulated sediment at five delta locations in Karth Lake. Also, three options were evaluated for improvements to the Karth Lake pump system to better monitor the lake level and possibly automate the pump operations. A summary of the estimated project costs associated with the design alternate and the estimated project costs associated with the three design options is presented in Table 3 below (includes 10% contingency and 27% overhead).

FUNDING & ASSESSMENTS 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 18 VIII. FUNDING & ASSESSMENTS Assessments for street improvement costs are proposed to be levied to benefiting properties as outlined in Minnesota Statute 429 and the City of Arden Hills Assessment Policy. A preliminary assessment roll was compiled for all adjacent benefitting properties per the City’s assessment policy and is included in Appendix C. Identified properties were proposed to be assessed at a calculated assessment rate of 50% of the street project costs for residential properties and 70% of the street project costs for commercial/industrial properties. The street project costs were split between mill & overlay improvements and reclamation improvements for each property zoning classification. To determine properties eligible for assessment, each property’s frontage and access to the street(s) proposed for improvements were evaluated (including access via private roads and shared driveways, specifically in the case of Cummings Park Drive). As indicated in the City’s assessment policy, properties with frontage abutting a street identified for improvement shall be assessed on a unit basis at the calculated assessment rate, however, corner lots shall be assessed on the street that is used for the mailing address. Further, “the City Council shall retain the right to review each project on its own merit and deviate from any portion of the Assessment Policy Manual, as it deems proper. These deviations may occur in unique situations or where application of the policy produces unfair or undesirable results. The residential equivalent assessment rate shall be determined by the City Council.” The project area includes a few unique property situations as it relates to the city’s assessment policy. Five of the industrial properties identified for assessments have access to Cummings Park Drive, either directly, from a private road, or from a shared driveway, but do not have a Cummings Park Drive address. Further, one of these properties has alternative access options to County Road F. Each of these properties have been included in the assessment calculations but the City Council should specifically evaluate these properties, in addition to the project as a whole, to determine if the City’s assessment policy was accurately applied. Assessments for the proposed street improvements were calculated using the Residential Equivalent Unit (REU) method as outlined in the City’s assessment policy. Each property eligible for assessment was identified as either a residential mill & overlay property, residential reclamation property, or industrial reclamation property based on the proposed street improvement classification and the associated property zoning. The assessable costs for each improvement/zoning category were divided by the number of eligible REU’s to determine an assessment rate for each improvement/zoning category. Calculations for the estimated assessment rates are provided below: Residential Mill & Overlay Areas 50% Estimated Street Project Costs = $81,500 Residential Equivalent Units = 21 Assessment Rate = $3,880 Residential Reclamation Areas 50% Estimated Street Project Costs = $614,500 Residential Equivalent Units = 105 Assessment Rate = $5,850 DRAFT Prepared by: Bolton & Menk, Inc. 2026 PMP Street & Utility Improvements ǀ 25X.137753 Page 19 Industrial Reclamation Areas 70% Estimated Street Project Costs = $280,000 Residential Equivalent Units = 334 Assessment Rate = $840 To ensure the calculations resulting from the application of the City’s assessment policy are in line with an appraiser’s opinion of benefit to the properties in each improvement/zoning category, the City enlisted the services of Nagell Appraisal & Consulting to conduct a general benefit appraisal on the properties throughout the project area. The general benefit appraisal is included in Appendix D. The general benefit appraisal resulted in a range of benefit values for each improvement/zoning category, as indicated below: Residential Mill & Overlay Areas Benefit Appraisal Assessment Rate Range = [IN PROGRESS] Residential Reclamation Areas Benefit Appraisal Assessment Rate Range = [IN PROGRESS] Industrial Reclamation Areas Benefit Appraisal Assessment Rate Range = [IN PROGRESS] [SUMMARIZE RESULTS OF BENEFIT APPRAISAL AND HOW IT RELATES TO CALCULATED ASSESSMENTS ONCE COMPLETED] See Figure 2 through Figure 4 in Appendix A for the assessable properties map that correlates with the parcel numbers on the preliminary assessment roll. The project costs for the remaining street costs and for the storm sewer, sanitary sewer, watermain, trails, and Karth Lake improvements will be the cost responsibility of the City. Proposed project funding sources are a combination of the City’s Permanent Improvements Revolving (PIR) fund, utility funds, special assessments for street improvements, possible grant funds if grant applications are successful, and the potential for KLID participation. The proposed project assessments and funding summary are based on preliminary estimated project costs for the recommended base project improvements. These costs may be revised at the time of the final assessment hearing depending on the final design of the project, required right- of-way and/or easements, soil conditions, bids received, and actual work performed. The assessments are proposed to be assessed over a 10-year period at an interest rate to be set by the City Council. A summary of the funding breakdown, exclusive of design alternates/options, is presented in Table 4 below.

CONCLUSION This report has been prepared to investigate the potential for rehabilitating the roadways in the 2026 PMP Street & Utility Improvements project areas and associated work. This report identified the recommended improvements to the infrastructure, provided estimated costs of the recommended improvements, and identified applicable funding to finance the improvements. From an engineering standpoint, this project, as proposed, is feasible, cost effective, and necessary and it can best be accomplished by letting competitive bids for the work. It is recommended that the work be done under one contract in order to complete the work in an orderly and efficient manner. The City and the persons assessed will have to determine the economic feasibility of the proposed improvements.

Project Description This Geotechnical/Pavement Evaluation Report addresses the proposed design and rehabilitation of the Arden Hills 2026 pavement management project (PMP) in Arden Hills, Minnesota. The 2026 PMP project areas are depicted in Figure 1. Figure 1. Project Rehabilitation Areas Figure annotated and extracted from Enterprise MnDOT Mapping Application (EMMA). We understand that proposed rehabilitation is anticipated to include new bituminous pavements through milling and overlaying or through reclaiming existing bituminous and apparent aggregate base material, then overlaying new bituminous. We also understand that the trail on the south side of Karth Lake will be rehabilitated. Additional site work may include spot curb and gutter repairs as well as spot utility repairs where the City of Arden Hills (City) has deemed necessary. Mill and Overlay Full-Depth Reclamation Trail Rehab Area City of Arden Hills Project B2502087 June 13, 2025 Page 2 Table 1 provides additional project specific details related to the 2026 PMP project. Table 1. Project Description for 2026 Street Rehabilitation Project Component Description Source Pavement type Bituminous City / Bolton & Menk, Inc. (BMI) Pavement rehabilitation method ▪Mill and Overlay (M&O) ▪Full-Depth Reclamation (FDR)City / BMI Pavement loads* Karth Lake Neighborhood: Less than 150,000 Bituminous ESALs (BESALs) Assumed Cummings Park Drive: Less than 250,000 BESALs Assumed based on on-site observations at time of drilling and based on vehicle traffic being mainly Boston Scientific employees (passenger car vehicles driving through the road corridor). Utilities Spot utility repairs, up to 10 feet below grade Assumed Cummings Park Trail FDR where bituminous and aggregate exist. Where aggregate exists only, tolerancing and paving over. BMI Grade changes Street grades will be within 1 foot of existing. Assumed *Equivalent 18,000-lb single axle loads based on 20-year design. We have described our understanding of the proposed construction and site to the extent others reported it to us. Depending on the extent of available information, we may have made assumptions based on our experience with similar projects. If we have not correctly recorded or interpreted the project details, the project team should notify us. New or changed information could require additional evaluation, analyses and/or recommendations. A.2. Site Conditions Currently, the project site exists as a residential neighborhood and a business entrance (Cummings Park Drive). The area is bounded by County Road 96 West to the north, Hamline Avenue North to the west, Boston Scientific to the south and Lexington Avenue North to the east. Current grades range from elevations of about 954.8 feet at Boring ST-14 to about 1007.4 feet at Boring ST-18. The project area generally contains hummocky topography, and regionally slopes downward from the northeast to the southwest near Karth Lake. City of Arden Hills Project B2502087 June 13, 2025 Page 3 A.3. Purpose The purpose of our geotechnical/pavement evaluation was to characterize subsurface geologic conditions at selected exploration locations, evaluate their impact on the project, and provide geotechnical recommendations for the design and construction of street rehabilitation using an assumed R-value, associated utility improvements, and trail improvements. A.4. Background Information and Reference Documents We reviewed the following information: ▪Email request with map regarding proposed scope of work from Bolton & Menk, Inc., received on February 12, 2025. ▪Geologic map titled M-178, Surficial Geology of the Twin Cities Metropolitan Area, Minnesota prepared by the Minnesota Geological Survey, dated 2007. ▪Traffic data available via the Minnesota Department of Transportation (MnDOT) Traffic Mapping Application, http://www.dot.state.mn.us/traffic/data/tma.html. ▪Enterprise MnDOT Mapping Application (EMMA), https://dotapp9.dot.state.mn.us/emma/. A.5. Scope of Services We performed our scope of services for the project in accordance with our Proposal for a Geotechnical/Pavement Evaluation (QTB210666) dated February 21, 2025 and authorized on March 10, 2025. The following list describes the geotechnical tasks completed in accordance with our authorized scope of services. ▪Reviewing the background information and reference documents previously cited. ▪Staking and coordinating the clearing of our exploration locations for underground utilities. We selected and staked the new exploration locations. We acquired the surface elevations and locations with GPS technology using the State of Minnesota’s permanent GPS base station network. The Soil Boring Location Sketch included in the Appendix shows the approximate locations of the borings and pavement cores. City of Arden Hills Project B2502087 June 13, 2025 Page 4 ▪Performing 19 standard penetration test (SPT) borings, denoted as ST-1 to ST-19, to nominal depths of 10 feet below existing grade. ▪Performing 4 hand auger borings (HABs) through trail areas, denoted as T-1 to T-4, to nominal depths of 2 to 4 feet below existing grade. ▪Performing laboratory testing on select samples to aid in soil classification and engineering analysis. ▪Preparing this report containing a boring location sketch, logs of soil borings, a summary of the soils encountered, results of laboratory tests, and recommendations for structure and pavement subgrade preparation and the design of foundations, floor slabs, exterior slabs, utilities, stormwater improvements and pavements. We performed this geotechnical evaluation concurrently with Sediment (Dredge) Sampling, which we submitted separately. The project team should review the Sediment Sampling report for work specific to Karth Lake. B.Results B.1. Geologic Overview The general geologic profile of the project area represented in Figure 2 below generally consists of Moderate- and high-relief glacial till deposits, such as silty sands, and clays forming hummocky, irregular topography (map unit’s ‘Qnh’ and ‘Qnm’). City of Arden Hills Project B2502087 June 13, 2025 Page 5 Figure 2. Surficial Geology Map of the Project Area Figure extracted from Map M-178, Surficial Geology of the Twin Cities Metropolitan Area. We based the geologic origins used in this report on the soil types, laboratory testing, and available common knowledge of the geological history of the site. Because of the complex depositional history, geologic origins can be difficult to ascertain. B.2. Ground Penetrating Radar (GPR) GPR was used to approximate pavement layer thicknesses along the road sections for the 2026 pavement management project (PMP). The data was collected at a nominal 1-foot interval. Where “ground truth” data (pavement cores) were performed, the interpreted layers from the GPR scan were compared directly to the measured thicknesses from the cores to improve the overall accuracy of the GPR analysis. The tables shown in the Appendix show summary statistics of the bituminous pavement layer thicknesses. The Graphical Results of the GPR can be found in the Appendix as well. We can provide complete results electronically at your request. A second layer (probable aggregate base) was not always visible in the scans, i.e., it was difficult to identify as a distinct layer due to ambient interference with the GPR signal. A lack of a visible second layer in the Qnm Project Area City of Arden Hills Project B2502087 June 13, 2025 Page 6 GPR scan does not imply an absence of one within the pavement section. Refer to our pavement core and hand auger boring results for approximate aggregate base depths in these locations. B.3. Pavement Core Results We performed pavement coring and hand auger borings at 23 locations along the various roads, as shown in the sketch in the Appendix. HABs were also performed through the aggregate base layer and into the shallow subgrade in core locations. The pavement cores and HABs were used to measure pavement layer thicknesses for the bituminous and aggregate base layers, to assess bituminous conditions, and determine the shallow subgrade soil type. The results are presented below. We did not perform gradation analysis on the apparent aggregate base material encountered as part of the pavement section, in accordance with our scope of work. Therefore, we cannot conclusively determine if the encountered material satisfies a particular specification. Table 2.

For simplicity in this report, we define fill to mean existing, uncontrolled or undocumented. City of Arden Hills Project B2502087 June 13, 2025 Page 8 B.5. Groundwater We did not observe groundwater while performing our borings. Groundwater may take days or longer to reach equilibrium in the boreholes and we immediately backfilled the boreholes, in accordance with our scope of work. If the project team identifies a need for more accurate determination of groundwater depth, we can install piezometers. Project planning should anticipate seasonal and annual fluctuations of groundwater. B.6. Laboratory Test Results We performed various laboratory tests on select soil samples to aid us in our evaluation. The Log of Boring sheets attached in the Appendix presents the results. Table 4 provides the range of results for the moisture contents, percent passing the #200 sieve, organic contents and Atterberg limits. Table 4. Laboratory Classification Test Results Laboratory Test Range of Results Comments Moisture content (MC) tests, % (per ASTM D2216) Cohesionless soils: 2 to 15 Cohesive soils: 11 to 26 Coarse-grained soils were typically dry to near the soil’s probable optimum moisture content. Fine-grained soils were generally moist but anticipated to be at- to slightly-above the probable optimum moisture content. Organic content (OC) tests, % (per ASTM D2974) 2 Considered slightly organic as classified by MnDOT definitions. Percent of particles passing the #200 Sieve, % (per ASTM D1140) 2 to 17 USCS Classifications: SP, SP-SM, SM Atterberg Limits (AL), % (per ASTM D4318) Liquid Limit (LL) – 22 Plastic Limit (PL) – 17 Plasticity Index (PI) – 5 USCS Classification: CL-ML C.Recommendations C.1. Design and Construction Discussion The recommendations provided herein are based on the information provided to us at the time of this report. As the project progresses through final design or elements of the project are adjusted, we should revisit our recommendations. City of Arden Hills Project B2502087 June 13, 2025 Page 9 References to the MnDOT Specification in this report are to Minnesota Department of Transportation (MnDOT) Standard Specification for Construction, 2025 edition. C.1.a. Rehabilitation Methods Based on our understanding that the 2026 PMP will utilize either mill and overlay or full depth reclamation (FDR), Table 5 presents our recommended pavement rehabilitation method for each of the identified roads. Table 5. Proposed Rehabilitation Approach Rehabilitation Method Location Mill-and-Overlay ▪Karth Lake Circle Full-Depth Reclamation (FDR) ▪Karth Lake Drive ▪Amble Drive ▪Amble Circle ▪Pleasant Drive ▪Pleasant Circle ▪Cummings Park Drive We understand that the recommended rehabilitation methods presented in Table 5 matches the planned rehabilitation methods the City was proposing. C.1.b. Karth Lake Park Trail We understand that Karth Lake Park Trail is also being considered for FDR as part of this rehabilitation project. With the encountered thin trail pavement section, we anticipate it will likely be difficult to perform an FDR and recommend stripping the bituminous, adding aggregate base and repaving on this project. Refer to Section C.5 for additional recommendations on Karth Lake Trail. C.1.c. Reuse of Pavement Materials From a materials perspective, milling or reclamation of the bituminous pavement materials for reuse as recycled aggregate base or as a component to new pavements is acceptable assuming the produced products meet the applicable project specifications, and these practices are acceptable to the City. Prior to reuse, the project should implement thorough quality control practices, including frequent sieve analyses, asphalt contents and other tests, to achieve desirable characteristics for any reclaimed material processed on site. City of Arden Hills Project B2502087 June 13, 2025 Page 10 C.1.d. Reuse of On-Site Soils Based on the completed laboratory testing program, the existing non-organic soils (both the naturally deposited soils and fill soils) on-site are generally considered suitable for reuse as engineered fill soil following moisture conditioning and compaction as outlined in this report. If encountered, organic fill soils are not considered suitable for reuse as engineered fill. Any materials to be used as engineered fill should be tested and approved by the engineer prior to placement. C.1.e. Groundwater Water was not encountered in any of the borings completed for this project. Groundwater may fluctuate in response to both seasonal and annual rainfall events. Surface runoff can collect in open excavation if left open during wet weather. If encountered, the water should be removed from excavations during construction and prior to placement of any utility structures. C.1.f. Construction Disturbance The existing soils encountered on-site, including clay-based soils, are highly susceptible to loss of strength when subjected to additional moisture or disturbance. The contractor should take precautions to limit the disturbance of these soils to the extent practical within the utility trench excavations. If disturbed, there is the potential that an additional subcut of these soils to depths of 2 to 3 feet may be necessary to re-establish a stable base for placement of engineered fill. In addition, a layer of stabilizing aggregate may be necessary to provide a stable working surface for construction. C.2. Site Grading and Subgrade Preparation We understand that as part of the 2026 pavement management project, there may be spot utility repairs in areas where FDR is to occur. The following sections under Section C.2 provide general site grading and subgrade preparation recommendations. C.2.a. Utility Subgrade Stabilization We anticipate the soils at typical invert elevations will be suitable for utility support. However, if construction encounters unfavorable conditions such as soft clay, organic soils or perched water at invert grades, the unsuitable soils may require some additional subcutting and replacement with sand or crushed rock to prepare a proper subgrade for pipe support. Project design and construction should not place utilities within the 1H:1V oversizing of foundations. Where soft/loose or organic soils are encountered below utility inverts, we recommend subcutting a minimum of 1-foot and replacing with crushed rock to help provide a stable working platform. City of Arden Hills Project B2502087 June 13, 2025 Page 11 C.2.b. Corrosion Potential Based on our experience, the soils encountered by the borings are moderately corrosive to metallic conduits, but only marginally corrosive to concrete. We recommend specifying non-corrosive materials or providing corrosion protection, unless project planning chooses to perform additional tests to demonstrate the soils are not corrosive. C.2.c. Excavation Oversizing When removing unsuitable materials below structures or pavements, we recommend the excavation extend outward and downward at a slope of 1H:1V (horizontal:vertical) or flatter. See Figure 3 for an illustration of excavation oversizing. Figure 3. Generalized Illustration of Oversizing C.2.d. Excavated Slopes Based on the borings, we anticipate most of the on-site soils in excavations will consist of fill sands and clays. These soils are typically considered Type C Soil under OSHA (Occupational Safety and Health Administration) guidelines. OSHA guidelines indicate unsupported excavations in Type C soils should have a gradient no steeper than 1 1/2H:1V. Slopes constructed in this manner may still exhibit surface sloughing. 1.Engineered pavement embankment fill as defined in Section C.2.f. 2.Excavation oversizing minimum of 1H:1V slope or flatter. 3.Backslope to OSHA requirements. 4.Outside edge of existing pavement. 5.Outside edge of new pavement. 6.Unsuitable soils to be removed. City of Arden Hills Project B2502087 June 13, 2025 Page 12 An OSHA-approved qualified person should review the soil classification in the field. Excavations must comply with the requirements of OSHA 29 CFR, Part 1926, Subpart P, “Excavations and Trenches.” This document states excavation safety is the responsibility of the contractor. The project specifications should reference these OSHA requirements. C.2.e. Excavation Dewatering We recommend removing groundwater that collects within excavations from rainfall events and/or surface runoff. Project planning should include temporary sumps and pumps for excavations in low- permeability soils, such as clays. Where granular soils are encountered at invert elevations, the design team may want to consider additional means and methods for removing groundwater, as sumps and pumps have the potential to loosen the granular soils at excavated bottoms. C.2.f. Engineered Fill Materials and Compaction Most on-site soils appear suitable for reuse as engineered fill within pavement subgrades and utility trenches, although some moisture conditioning may be required (drying or wetting of materials). If encountered, topsoil and soils with organic contents of greater than 5 percent by weight should not be reused as pavement subgrade or utility trench backfill anywhere on the project. Organic soils can be stockpiled for use as a component in topsoil dressing, side slopes or in other areas where loads are not supported. Any materials to be reused as engineered fill should be tested and approved by the engineer prior to reuse. We recommend that subgrade fill materials and compaction are in accordance with the MnDOT specifications presented in Table 6. Table 6. Engineered Fill Materials and Compaction Specifications Material Material Specification Compaction Specification Embankment fill, Utility trench backfill Common Embankment MnDOT 2106.2.B.1 MnDOT 2106.3.G.1 Pavement subbase Select Granular Material MnDOT 3149.2.B MnDOT 2106.3.G.3 Below landscaped surfaces, where subsidence is not a concern Non-Structural Grading Material MnDOT 2106.1.A.8 MnDOT 2106.3.G.2 We recommend spreading engineered fill in loose lifts of approximately 8 to 12 inches thick for granular soils and for cohesive soils, we recommend spreading in loose lifts of approximately 6 to 8 inches thick. We recommend performing moisture and density tests in engineered fill to evaluate if the contractors are effectively compacting the soil and meeting project requirements. City of Arden Hills Project B2502087 June 13, 2025 Page 13 The project documents should not allow the contractor to use frozen material as engineered fill or to place engineered fill on frozen material. Frost should not penetrate under foundations during construction. C.3. Full-Depth Reclamation We understand that the FDR is proposed for the areas presented in Table 5. For the proposed FDR on the residential streets, for reuse of pavement materials by reclamation, we recommend a 10-inch FDR for most of the project streets. Due to the thinner pavement section and clayey subgrade, we recommend the FDR depth be reduced to 8 inches on Karth Lake Circle, Amble Circle, and Pleasant Circle between Lexington Avenue and Pleasant Drive. To place the full aggregate base section in these areas, an additional removal of 2 inches of subgrade material may be needed. Based on the measurements from the borings and pavement cores, this generally will avoid subgrade soils. If there are areas where subgrade may be penetrated due to a thinner pavement section, we recommend reducing the mill depth to the top of subgrade and excavating to the design depth of the pavement section. We recommend implementing through quality control practices, including frequent sieve analyses, to achieve a desirable gradation of the reclaimed material. The gradation requirements of MnDOT Specification 2215 (Reclamation) or Specification 3138 (Aggregate for Surface and Base Courses) can be used for the aggregate base; the latter specification’s controls on gradation and asphalt content are stricter and will generally be more difficult to meet. We suggest the contractor assume some contingency for importing clean, crushed rock that can be blended with the reclaimed material to improve the uniformity of the resulting gradation prior to reuse as an aggregate base. For the Karth Lake Trail, we understand the intent was to reclaim the trail and repave. Understanding the trail had limited pavement and aggregate base present, we recommend stripping the pavement adding additional aggregate to the existing apparent aggregate base and then placing new pavement for the trail. See section C.5 for recommendations with regards to the trail. C.3.a. Full-Depth Reclamation Preparation We recommend the following steps for pavement reclamation preparation, understanding the new pavements will match existing grades. 1.Reclaim the pavement as recommended under Section C.3., stockpile and/or redistribute excess reclaim material as necessary to construct the new pavement sections. City of Arden Hills Project B2502087 June 13, 2025 Page 14 2.Once the roadway section is cut to grade, have a geotechnical engineer or their representative observe the top of reclaim material (and/or subgrade if material below reclaim becomes exposed or wet) to evaluate if additional improvements are necessary. C.3.b. Full-Depth Reclamation Design Section For the FDR process, the pavement should generally follow Table 7. Table 7. Proposed Bituminous Pavement Section Material Thickness (inches) Material Material Specification Bituminous wear course 1 1/2 SPWEA340C MnDOT 2360 Bituminous wear course 2 1/2 SPWEB330C MnDOT 2360 Aggregate base 6 Reclaim* MnDOT 2215 Aggregate base Varies --- Residual aggregate base Approved subgrade --- --- --- *Where reclaim is removed for spot utility repair, material specification will generally follow MnDOT 2211, class 5 material. C.3.c. Bituminous Pavement Materials and Compaction We recommend that the bituminous wear and non-wear courses meet the requirements of Specifications 2360. We recommend compacting the aggregate base to meet the requirements of MnDOT Specification 2211.3.D.2.c (Penetration Index Method for the dynamic cone penetrometer [DCP]). We recommend compacting bituminous pavements to at least 92 percent of their maximum theoretical (Rice) density. C.3.d. Performance and Maintenance We based the above pavement designs on a 20-year performance life for bituminous. This is the amount of time before we anticipate the pavement will require reconstruction. This performance life assumes routine maintenance, such as seal coating and crack sealing. The actual pavement life will vary depending on variations in weather, traffic conditions and maintenance. Many conditions affect the overall performance of pavements. Some of these conditions include the environment, loading conditions and the level of ongoing maintenance. With regard to bituminous pavements in particular, it is common to have thermal cracking develop within the first few years of placement and continue throughout the life of the pavement. We recommend developing a regular maintenance plan for filling cracks in exterior slabs and pavements to lessen the potential impacts for cold weather distress due to frost heave or warm weather distress due to wetting and softening of the subgrade. City of Arden Hills Project B2502087 June 13, 2025 Page 15 C.3.e. Miscellaneous Bituminous Recommendations When placing new pavement next to in-place pavement, we recommend providing a full-depth sawcut to ensure a uniform joint. We recommend tack coat between all bituminous layers and prior to placing any bituminous mixtures on existing pavement in accordance with MnDOT Specification 2357. C.4. Mill-and-Overlay We recommend milling the pavements for Karth Lake Circle in accordance with MnDOT Specification 2232. The mill depth will vary based on conditions encountered but should be a minimum depth of 2 1/2 inches. Following the milling, place a 2 1/2-inch bituminous overlay meeting bituminous wear course mix SPWEA340B (MnDOT Material Specification 2360). Pavement depth can vary between the boring and core locations. The contractor may need to adjust the mill depth to account for unexpected conditions such as areas of thin pavement. The surface condition prior to milling can indicate where deeper repairs to the milled surface may be necessary to improve the life of the overlay. This includes distresses such as severe longitudinal and transverse cracking, alligator/fatigue cracking of any severity, potholes, edge cracking, and similar failures. MnDOT defines these distresses in their surface rating procedure as follows: ▪High-severity transverse cracking: Any crack running transverse to the centerline of the roadway with significant adjacent random cracking (12 inches or more apart), have large areas of spalling, missing material and/or potholes. ▪High-severity longitudinal cracking: Any crack running parallel to the centerline of the roadway with significant adjacent random cracking (12 inches or more apart), large areas of spalling, missing material and/or potholes. ▪Alligator cracking: A series of interconnected cracks forming many-sided, sharp-angled pieces, 6 inches or less in size, typically located in the wheel paths and under concentrated traffic loads. We recommend an experienced engineer walk the milled surface to delineate areas for these repairs based on conditions exposed by the milling process. We recommend performing the full-depth mill to at least 1 foot beyond the edge of the visible distresses where present. City of Arden Hills Project B2502087 June 13, 2025 Page 16 C.5. Karth Lake Park Trail We understand that Karth Lake Park Trail is not anticipated to touch the subgrade and will be limited to removal of existing bituminous pavement, placing additional aggregate base down and then repaving. The following subsections provide general recommendations for this work. C.5.a. Base Grade Proofroll After preparing the aggregate base, we recommend proofrolling the aggregate base with a fully loaded tandem-axle truck. We also recommend having a geotechnical representative observe the proofroll. Areas that fail the proofroll likely indicate soft or weak areas that will require additional soil correction work to support pavements. The contractor should correct areas that display excessive yielding or rutting during the proofroll, as determined by the geotechnical representative. If the aggregate base proofroll shows signs of distress, possible options could be to correct the subgrade which could include moisture conditioning and recompaction, subcutting and replacement with soil or crushed aggregate, chemical stabilization and/or geotextiles. If subgrade corrections occur, we recommend performing a second proofroll after the aggregate base material is in place (where aggregate base was removed), and prior to placing bituminous pavement. C.5.b. Design Sections Our scope of services for this project did not include laboratory tests on subgrade soils to determine an R-value for pavement design. Based on our experience with similar _ soils anticipated at the pavement subgrade elevation, we recommend pavement design assume an R-value of _. Note the contractor may need to perform limited removal of unsuitable or less suitable soils to achieve this value. Table X provides recommended pavement sections, based on the soils support and traffic loads. Table 8.

D.Procedures D.1. Ground Penetrating Radar D.1.a. Data Collection GPR data was collected in May of 2025. GPR collection occurred at posted speed limits and data was recorded continuously along the pavement to a depth of up to 2 feet. Analysis of this data provides a continuous estimate of layer thickness for identifiable layers. Scans of the pavement were collected according to GSSI, Inc. (manufacturer) SIR-30 processor settings at a specified interval of approximately one scan per lineal foot in the outer wheel path. A calibration file, required for data post-processing, was collected at the onset of testing. The RoadScan system from GSSI, Inc. allows for the entry of user marks to note events. This capability was used to mark and tie in core locations. Distance along the pavement is measured using a Distance Measuring Instrument (DMI). D.1.b. GPR Analysis Data collected by the GPR unit was returned to our office and analyzed to estimate the pavement thickness. Pavement layer interpretation was accomplished using RADAN 7.0, a software package included with the GSSI RoadScan system. The software includes tools to aid in delineating pavement layer transitions and automatically calculates their depths from the pavement surface using the calibration file(s) collected prior to or following testing. Where “ground-truth” data (cores and hand augers) were performed, the interpreted layers from the GPR scan were compared directly to the measured thicknesses from the borings to validate the accuracy of the GPR analysis. D.2. Pavement Coring and Hand Auger Borings We performed pavement cores and hand auger borings in April of 2025. Exploration locations were selected based on GPR results. The coring was performed with a 6-inch diameter diamond-toothed core barrel fitted on a mechanically operated rotary drill. From the top of the apparent aggregate base layer, we extended a manually operated hand auger through the base layer and into the subgrade layer. Upon completion of the pavement cores and hand augers, we then performed our penetration test borings. City of Arden Hills Project B2502087 June 13, 2025 Page 18 The cores were measured to obtain approximate bituminous thicknesses, and their material conditions were noted based on visual observation. A sample of underlying base material was obtained at each of the exploration locations and was sent to our laboratory for review by a geotechnical engineer. D.3. Penetration Test Borings We drilled the penetration test borings with a GeoProbe-mounted core and auger drill equipped with hollow-stem auger. We performed the borings in general accordance with ASTM D6151 taking penetration test samples continuously to a depth of 6 feet below existing grade, then at 2 1/2-foot intervals in general accordance to ASTM D1586. The boring logs show the actual sample intervals and corresponding depths. D.4. Exploration Logs D.4.a. Log of Boring Sheets The Appendix includes Log of Boring sheets for our penetration test borings. The logs identify and describe the penetrated geologic materials, and present the results of penetration resistance tests performed. The logs also present the results of laboratory tests performed on penetration test samples, and groundwater measurements. We inferred strata boundaries from changes in the penetration test samples and the auger cuttings. Because we did not perform continuous sampling, the strata boundary depths are only approximate. The boundary depths likely vary away from the boring locations, and the boundaries themselves may occur as gradual rather than abrupt transitions. D.4.b. Geologic Origins We assigned geologic origins to the materials shown on the logs and referenced within this report, based on: (1) a review of the background information and reference documents cited above, (2) visual classification of the various geologic material samples retrieved during the course of our subsurface exploration, (3) penetration resistance performed for the project, (4) laboratory test results, and (5) available common knowledge of the geologic processes and environments that have impacted the site and surrounding area in the past. City of Arden Hills Project B2502087 June 13, 2025 Page 19 D.5. Material Classification and Testing D.5.a. Visual and Manual Classification We visually and manually classified the geologic materials encountered based on ASTM D2488. When we performed laboratory classification tests, we used the results to classify the geologic materials in accordance with ASTM D2487. The Appendix includes a chart explaining the classification system we used. D.5.b. Laboratory Testing The exploration logs in the Appendix note most of the results of the laboratory tests performed on geologic material samples. The remaining laboratory test results follow the exploration logs. We performed the tests in general accordance with ASTM procedures. D.6. Groundwater Measurements The drillers checked for groundwater while advancing the penetration test borings, and again after auger withdrawal. We then filled the boreholes or allowed them to remain open for an extended period of observation, as noted on the boring logs. E.Qualifications E.1. Variations in Subsurface Conditions E.1.a. Material Strata We developed our evaluation, analyses and recommendations from a limited amount of site and subsurface information. It is not standard engineering practice to retrieve material samples from exploration locations continuously with depth. Therefore, we must infer strata boundaries and thicknesses to some extent. Strata boundaries may also be gradual transitions, and project planning should expect the strata to vary in depth, elevation and thickness, away from the exploration locations. Variations in subsurface conditions present between exploration locations may not be revealed until performing additional exploration work, or starting construction. If future activity for this project reveals any such variations, you should notify us so that we may reevaluate our recommendations. Such variations could increase construction costs, and we recommend including a contingency to accommodate them. City of Arden Hills Project B2502087 June 13, 2025 Page 20 E.1.b. Groundwater Levels We made groundwater measurements under the conditions reported herein and shown on the exploration logs, and interpreted in the text of this report. Note that the observation periods were relatively short, and project planning can expect groundwater levels to fluctuate in response to rainfall, flooding, irrigation, seasonal freezing and thawing, surface drainage modifications and other seasonal and annual factors. E.2. Continuity of Professional Responsibility E.2.a. Plan Review We based this report on a limited amount of information, and we made a number of assumptions to help us develop our recommendations. We should be retained to review the geotechnical aspects of the designs and specifications. This review will allow us to evaluate whether we anticipated the design correctly, if any design changes affect the validity of our recommendations, and if the design and specifications correctly interpret and implement our recommendations. E.2.b. Construction Observations and Testing We recommend retaining us to perform the required observations and testing during construction as part of the ongoing geotechnical evaluation. This will allow us to correlate the subsurface conditions exposed during construction with those encountered by the borings and provide professional continuity from the design phase to the construction phase. If we do not perform observations and testing during construction, it becomes the responsibility of others to validate the assumption made during the preparation of this report and to accept the construction-related geotechnical engineer-of-record responsibilities. E.3. Use of Report This report is for the exclusive use of the addressed parties. Without written approval, we assume no responsibility to other parties regarding this report. Our evaluation, analyses and recommendations may not be appropriate for other parties or projects. E.4.

The reported N‐value is the blows per foot recorded by summing the second and third interval in accordance with the Standard Penetration Test, ASTM D1586. PartialPenetration:If the sampler could not be driven through a full 6‐inch interval, the number of blows for that partial penetration is shown as #/x" (i.e. 50/2"). The N‐value is reported as "REF" indicating refusal. Recovery: Indicates the inches of sample recovered from the sampled interval. For a standard penetration test, full recovery is 18", and is 24" for a thinwall/shelby tube sample. WOH: Indicates the sampler penetrated soil under weight of hammer and rods alone; driving not required. WOR: Indicates the sampler penetrated soil under weight of rods alone; hammer weight and driving not required. Water Level: Indicates the water level measured by the drillers either while drilling ( ), at the end of drilling ( ), or at some time after drilling ( ). Moisture Content: Dry:Absence of moisture, dusty, dry to the touch. Moist: Damp but no visible water. Wet: Visible free water, usually soil is below water table. 5/2021 Core #: ST-1 Project: B2502087 Pavement thickness 5 1/2 inches Agg base thickness: 5 inches Project Name: Arden Hills 2026 PMP Date: April 1, 2025 Notes: Upper 2” high deterioration; Debonded at 2”; Low severity stripping in bottom 3 1/2 inches.

AA/EOE Sediment (Dredge) Sampling 2026 PMP Street and Utility Improvements Karth Lake Arden Hills, Minnesota Prepared for City of Arden Hills Project B2502087 May 15, 2025 Braun Intertec Corporation AA/EOE Braun Intertec Corporation 11001 Hampshire Avenue S Minneapolis, MN 55438 Phone: 952.995.2000 Fax: 952.995.2020 Web: braunintertec.com May 15, 2025 Project B2502087 Mr. David Swearingen, PE City of Arden Hills 1245 W Hwy 96 Arden Hills, MN 55112 Re: Sediment Sampling 2026 PMP Street and Utility Improvements - Karth Lake Arden Hills, Minnesota Dear Mr. Swearingen: As authorized, Braun Intertec Corporation completed sediment sampling activities at the above-mentioned Karth Lake in Arden Hills, Minnesota (the Site). The objective of the work was to characterize the in-place sediment (future dredge material) for potential disposal purposes. Sediment Sampling Procedures The Site is located within Karth Lake. As such, our scope was based on the Minnesota Pollution Control Agency’s (MPCA) current best management practice for “Managing Dredged Materials,” dated August 2024 (MPCA, 2024). We collected five analytical samples from the proposed dredge areas, which are downstream of stormwater outfalls into the lake. The samples were collected by driving a core into the underlying sediment using direct push sampling equipment. During sampling activities, sediment sample textures were evaluated by visual methods as the samples were collected and noted in the field notes. Coring tools were cleaned prior to and between sampling runs by washing the equipment with a brush and potable water containing Alconox® and rinsing the equipment with deionized water. The samples were transferred to clean laboratory-supplied containers, preserved in accordance with Braun Intertec Standard Operating Procedures (SOPs) and transported to Pace Analytical Services laboratory for analysis. Chain of Custody was initiated at the time of sampling and maintained throughout the process. The sample locations are depicted on Figure 1. City of Arden Hills Project B2502087 May 15, 2025 Page 2 Sample Analytical Parameters Five samples were analyzed for the baseline sediment parameters pursuant to MPCA guidelines. The parameters were as follows: Metals – arsenic, cadmium, chromium III, chromium VI, copper, lead, mercury, nickel, selenium, and zinc by SW-846 EPA 6020/7471B. Total phosphorus using method EPA 365.1. Nitrate & nitrite using EPA 353.2. Ammonia nitrogen using EPA 350.1. Total Kjeldahl nitrogen using EPA 351.2. Polychlorinated biphenyls (PCBs) using method SW-846 8082A. Total organic carbon using SW-846-9060. Extended List, Polycyclic Aromatic Hydrocarbons (PAHs) using EPA 8270E SIM. Results Sediment Profile Sediments observed during the completion of the borings consisted primarily of a dark brown to black silty sand. Organic/decay odors were noted in the material collected from the O-2 through O-5 borings. Sediment Chemistry The results of laboratory analysis are summarized in Table 1. The laboratory analytical reports are also enclosed. PAHs PAHs were detected at or above the reporting limit within each sample analyzed. Non-carcinogenic PAHs were not reported at concentrations greater than Tier 1 SRVs. The benzo(a)pyrene (BaP) equivalent for the samples varied. Calculated concentrations ranged from below the Tier 1 and 2 Soil Reference Values (SRVs) within O-1, to between the Tier 1 and 2 SRVs within O-2, O-4, and O-5, to above the Tier 2 SRV within O-3. City of Arden Hills Project B2502087 May 15, 2025 Page 3 PCBs PCBs were not detected at or above the laboratory reporting limit in the samples analyzed, thus total reported PCBs for each analyzed sample were below the Tier 1 and 2 SRVs. Metals Cadmium, hexavalent chromium, selenium and mercury were not detected at or above the reporting limit (RL) within the sample analyzed. Arsenic, total chromium, copper, lead, nickel and zinc were detected at concentrations above the laboratory reporting limit within the sample analyzed. However, the concentrations were less than the Tier 1 and Tier 2 SRVs established for each compound. Other Ammonia, total Kjeldahl nitrogen, nitrate + nitrite, total phosphorous, and total organic carbon were detected at various concentrations in the samples. Management criteria have not been established for these compounds. We understand that the MPCA requirement to include these compounds is geared toward end-use of the dredged sediments and the results should be provided to disposal facilities or receiving parties for their use. Additional consultation with the MPCA regarding land application criteria and approvals may be required. Please refer to Table 1 for a detailed summary of the analytical results. Quality Assurance/Quality Control A data quality assessment of field procedures and laboratory reports was performed to determine the effect of any deviations on data quality and used to support project objectives. All applicable Braun Intertec SOPs were followed as prescribed unless otherwise noted in this report. Notable findings are provided in more detail below and incorporated, where necessary, into this report. Soil samples were placed in clean, laboratory-supplied containers, preserved, labeled, and transported to Eurofins laboratory in Cedar Falls, Iowa and Pace laboratory in Minneapolis, Minnesota under refrigerated conditions using chain-of-custody procedures. Eurofins subcontracted hexavalent chromium to Eurofins laboratory in Pittsburgh, Pennsylvania and total organic carbon (TOC) analysis to Eurofins laboratory in Arvada, Colorado. Chain-of-custody forms were reviewed at sample check-in and determined to be in general agreement with the contents of the sample coolers. Analyses were performed using EPA or other recognized standard procedures, and samples were analyzed within the EPA recommended holding times. City of Arden Hills Project B2502087 May 15, 2025 Page 4 Laboratory reporting limits were compared against Dredge Management Level 1 limits which utilize MPCA Residential/Recreational SRVs for soil samples. Detection limits for the compounds analyzed during the investigation met their respective regulatory standards. The recoveries and/or relative percent differences (RPD) of benzo(g,h,i)perylene, fluoranthene, phenanthrene, and pyrene were outside of method acceptance criteria in the matrix spike/duplicate (MS/D) samples for parent sample O-1. These analytes are considered estimated in O-1, but their regulatory limits are several orders of magnitude greater than the results. The recoveries and/or RPDs of numerous cPAHs were outside of method acceptance criteria in the MS/D samples for parent sample O-1. The recoveries of the affected analytes are within the expanded lower acceptance limits according to the National Functional Guidelines and are acceptable for use in this investigation. Detections of the affected analytes are considered estimated, and non-detected analytes have estimated quantitation limits. The RPDs of chromium, nickel, and zinc were above method acceptance criteria in the duplicate of sample O-4. These results are considered estimated, but they are below the regulatory limits. The recoveries of nitrite and nitrate-nitrite as N were below method acceptance criteria in the MS/D samples for parent sample O-1. These analytes were not detected in O-1, and the quantitation limits are considered estimated; however, regulatory limits have not been established for these analytes. In summary, data quality control items identified during the quality review were evaluated and all data collected are acceptable for use in this investigation for the intended purpose of identifying sediment impacts within the area of concern. Recommendations Based on the analytical results from our sampling, sediments at the Site fall into each of the dredge management levels established by MPCA. Level 1 Dredged Material is suitable for beneficial use on properties with a residential or recreational use category. Sediment at O-1 is at or below the Tier 1 SRVs, and as such, meets the Level 1 characteristic. Level 2 Dredged Material is suitable for beneficial use on properties with an industrial use category. Sediment at O-2, O-4, and O-5 is at or below the Tier 2 SRVs, and as such, meets the Level 2 characteristic. City of Arden Hills Project B2502087 May 15, 2025 Page 5 Level 3 Dredged Material is not suitable for use or reuse. Sediment at O-3 is above the Tier 2 SRVs, and as such, meets the Level 3 characteristic. Per MPCA 2024 guidance, “if subsets of Management Levels exist within the project, dredged material may be: “managed separately by levels, i.e. each subset of dredged material is managed at the relevant Management Level; managed at the most restrictive Management Level, if separation and management by subset is not feasible or desired; or, managed at the most restrictive Management Level if subsets from a given project or multiple project, such as at a use/reuse staging area, are co-mingled prior to disposal.” [breaks and bullets added for readability] General Our scope of our work was determined by our understanding of the rules and guidance of the MPCA as they apply to needs of the City of Arden Hills. Therefore, the scope of work is not represented to conform explicitly to current MPCA written guidance. We appreciate the opportunity to provide our professional services on this project and look forward to working with you in the future.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute.

Background At the May 12th and 28th work sessions, the City Council began the review of the HKGi Summary of Work Session #2 memo and recommendations. Feedback was given on the Lot Standards and Site Standards portion of the memo. During the review of the Permitted and Accessory Use Tables, the City Council tabled the discussion on the remainder of the Land Use Table review and remaining items in the consultant memo to a future work session. Below are the remaining discussion items that staff is looking for direction from the City Council on which will then be shared with HKGi: • Principal and Accessory Use Tables – HKGi has prepared the proposed principal and accessory use tables for non-residential zoning districts. The consultants have made recommendations on revisions for naming of uses and optional additional non-residential uses to consider, as well as those uses for discussion of transitioning to Permitted with Standards. The consultants are not proposing to remove Conditional Uses altogether, but this would allow the City to apply the same conditions and would remove some barriers to development (i.e. application review time and expense). o Permitted Use has few additional standards beyond the usual lot and site requirements such as lot size, yard setbacks, height, impervious coverage, etc. o Conditional Use requires a public hearing to ensure that any potential impacts to surrounding properties are mitigated through conditions that are tailored to the specific use and circumstances. Page 2 of 2 o Permitted with Standards do not require a public hearing but do have additional performance requirements listed in code that must be evaluated by Planning staff to ensure they are being met before a proposed project may apply for a building permit. • Development Standards - HKGi reviewed existing ordinance language and discussed with the Planning Commission several other development standards for parking, signage, landscaping, exterior storage, and outdoor lighting which are summarized in their memo to the City Council. On July 9th, HKGi will have a third Work Session with the Planning Commission focused on use specific standards, the subdivision code, and various procedures for land use applications.

The report to the Planning Commission is attached. This summary memo is intended to brief the City Council on the material presented, the questions and discussions that occurred, and the general direction offered by the Planning Commission. WORK SESSION TOPICS Two broad topics and several sub-topics were discussed at the second work session; the discussion around each will be summarized in turn: • Nonresidential and Mixed Use Districts o Lot and Site Standards (District Requirements) o Principal and Accessory Use Tables (Land Use Charts) • Development Standards o Parking o Signage o Landscaping o Exterior Storage (Commercial) o Outdoor Lighting NONRESIDENTIAL AND MIXED USE DISTRICTS Lot Standards HKGi focused on the lot standards for the Business Park (former B -4) and Gateway Business zoning districts and recommended simplifying both the use types that were addressed as well as the minimum lot sizes that were associated with those uses. This would help reduce confusion as well as bring a number of existing nonconforming lots into compliance. Of the nine properties in the B-4 district, none meet the current 5 acre minimum. Of the 10 developed lots in the GB district, only one is more than 20 acres and only two are more than 10 acres. City Council Summary Memo – Work Session #2 – Zoning Ordinance Update– May 6, 2025 2 Existing Lot Standards District Use type Minimum Lot Area B-4 Mixed Use Project or Multiple Occupancy Center 5 acres Single Use Project or Freestanding Building 2 acres Gateway Business Non-Residential Uses 5 acres Mixed Use Project or Multiple Occupancy Center 20 acres Single Use Project or Freestanding Building 10 acres Proposed Lot Standards District Use type Minimum Lot Area Business Park --- 2 acres Gateway Business --- 5 acres Commissioners agreed that changing the minimum standards to allow more lots to be conforming was a good objective. They did not see the need to distinguish between multiple occupancy and single use projects, and supported the recommendations for updating the lot standards. Site Standards Looking at the site standards for nonresidential and mixed use zoning districts, HKGi recommended reducing the required front yard setback for the Mixed Use (B-2) zoning district to help support a pedestrian and bicycle friendly street environment. This would allow buildings to be placed closer to the street and could encourage parking lots to locate to the side or rear of buildings. The corner side yard setback in the B-2 district is already set at 20 feet – the front yard setback should match this. The 50 foot front yard setbacks in the Corridor Business (B-3) and Business Park (B-4) districts could also be reduced. Commissioners supported this approach to creating better pedestrian environments. HKGi noted that the maximum height of 35 feet is currently exceeded in both the I -1 and INST districts (Boston Scientific as well as Bethel and Northwestern). Staff noted that these campuses were likely approved via PUD and that allowed the exception. Comm issioners suggested that rather than increase the maximum height by-right across these districts, additional height could be allowed by Conditional Use Permit so that individual proposals could be evaluated. Many of the lots in the Business Park (B-4) zoning district have lot coverage in excess of the 25% allowed. HKGi recommended increasing this amount to 40% to make more of the lots conforming. On a related note, the minimum amounts of required landscaping in the B-4 and CC districts are currently 25% and 20% respectively. A low maximum lot coverage for structures (smaller building footprints) combined with a low minimum landscaped area may encourage extensive surface parking lots. HKGi recommended bringing these standards into better alignment in order to encourage the right amount of landscaping. Commissioners agreed. City Council Summary Memo – Work Session #2 – Zoning Ordinance Update– May 6, 2025 3 Principal and Accessory Use Tables HKGi proposed two use tables – one for Principal Uses and a second for Accessory Uses. The proposed Principal Use table was reorganized from an alphabetical list to one organized by use categories and sub-categories. The labels of some uses were revised to aid in understanding what use was being described, while a handful of uses that are not currently included were suggested as optional additions. Based on the updated zoning district purpose statements, HKGi suggested changes to the districts in which certain uses were allowed. Finally, for a number of uses HKGi recommended adjusting how a use was permitted – by-right, with standards, conditionally, or prohibited. The full tables showing all recommended changes are attached. A few specific comments about the use tables are noted here: 1. The way in which the current CC district is described allows for a wide range of uses – from residential to funeral home to school to restaurant to fitness clubs. This may have been appropriate when the district was envisioned as a mixed use community center, but with the current focus on government services the types of uses allowed has been significantly reduced. 2. It is recommended that multifamily be removed as a use from the GB district. If they City wants to support a multifamily development south of Round Lake , a better approach would be to rezone the parcel(s) appropriately. 3. HKGi suggests splitting Automotive Service Stations into Major and Minor in order to restrict more impactful activities from less intense districts such as the MU district. Similarly, dividing Retail Sales and Services between Large and Small would allow for more targeted placement of commercial activities. The appropriate threshold size to make the distinction between Large and Small would need to be determined. 4. Because the I-2 district was eliminated, Exterior Storage is recommended to be allowed as an accessory use in the I-1 as permitted with standards. This would accommodate the existing lumberyard. Commissions asked a few questions, but also requested time to review the use tables in more detail and provide comments or revisions following the meeting. One set of comments was received following the work session. DEVELOPMENT STANDARDS Parking HKGi reviewed the existing parking standards and proposed changes to (a) better align the uses with those in the Principal Use table, and (b) simplify and in some cases slightly reduce the amount of parking required for certain uses. Draft standards for Electric Vehicle (EV) charging stations were also shared, aiming to balance requirements for the installation of EV charging stations for some uses while only requiring other uses to be “EV ready.” Commissioners had a handful of questions about proposed changes in parking standards, but felt the approach to EV charging was appropriate for Arden Hills. City Council Summary Memo – Work Session #2 – Zoning Ordinance Update– May 6, 2025 4 Signage Staff and the Planning Commission shared that their perception was that a better approach to maximum sign area was needed, perhaps based on a percentage of the building façade. HKGi discussed moving away from the use of Sign Districts, what do not have clear boundaries to show which parcels are included, and instead moving to aligning sign standards with zoning districts, as is done in most communities. Accommodations would be made to ensure businesses that front on major roadways have additional sign area allowances. Dynamic displays were discussed and Commissioners were open to expanding their use beyond menu signs to other uses, but did want to have tight controls on potential impacts such as movement, flashing, brightness, etc. It was also requested that the use of lights as a form of “signage” or advertising be addressed. Landscaping HKGi noted that Arden Hills requires tree planting based on a formula tied to the gross square footage of the structure. In other communities that have recently updated their zoning codes, this approach has occasionally resulted in too many trees being required on-site, with a result that some may be crowded and not grow in a healthy manner and potentially need to be removed at a later date. These cities have taken a new approach which determines the number of trees required based on the amount of pervious or landscaped area on the site, in additional to any street or parking lot tree requirements. Commissioners were wary of reducing the number of trees that a developer might need to plant, but acknowledged that overplanting was also not a good outcome. HKGi will analyze recent developments in Arden Hills and compare the two approaches to tree requirements in order to understand how they might differ. Exterior Storage (Commercial) HKGi covered a handful of recommended code adjustments to help address the outdoor storage of commercial vehicles and equipment. Commissioners were supportive of the approach suggested. Outdoor Lighting Discussion of outdoor lighting centered on the need to control excessive lighting that might be a nuisance to adjacent residential properties. Commissioners suggested looking at Dark Sky lighting standards and incorporating them into the zoning code. OTHER UPDATES Commissioners asked about the likelihood that property rezonings will be needed. HKGi confirmed that this question will be addressed towards the end of the project. Staff has already identified a handful of properties that should be rezoned in order to come into alignment with the City’s Future Land Use Map in the 2040 Comprehensive Plan. Following changes to zoning standards being considered as part of the update, it may be that some lots fit better in another district. If so, these additional lots would be identified for potential rezoning actions. City Council Summary Memo – Work Session #2 – Zoning Ordinance Update– May 6, 2025 5 Public engagement is anticipated to take place through three avenues in the early summer. Staff will help prepare an update for the City newsletter to be published in June/July. This update will contain a link to a project page on the City’s web page, wher e a summary of the work that is being done will be posted. HKGi will work with staff to develop targeted questions that address topics regulated through the City’s zoning requirements as a way to gather additional feedback on how the code should be updated. NEXT STEPS The third work session, tentatively scheduled for June, will focus on use specific standards, the subdivision code, and various procedures for land use applications. Draft code language associated with the topics that were discussed at the second work session will be shared with the Planning Commission at that time. ATTACHMENT • Memo to the Planning Commission dated April 9, 2025 HKGi 800 Washington Ave N Suite 103, Minneapolis, Minnesota 55401 (612) 338-0800 ~ www.hkgi.com PLANNING COMMISSION REPORT TO: City of Arden Hills Planning Commission FROM: Jason Zimmerman and Kendra Ellner, Consulting Planners DATE: April 3, 2025 SUBJECT: Zoning and Subdivision Ordinance Revisions – Work Session #2 MEETING DATE: April 9, 2025 OVERVIEW HKGi was selected by the City of Arden Hills to complete an update to the existing Zoning and Subdivision ordinances. The Planning Commission, as the body most involved with the application of the code, will help conduct a technical review of the proposed changes and provide recommendations to the City Council. The first work session covered some of the foundational elements upon which the rest of the ordinances will be built – base zoning districts, residential uses, and the required lot and site standards. BACKGROUND The current zoning and subdivision ordinances were adopted in 1993 but have been amended several times since – occasionally resulting in inconsistencies and poor formatting. In addition, procedures and some content need to be updated to reflect modern administration and new tools and technologies. HKGi has conducted a full evaluation of the current code and will be working throughout 2025 to meet with the Planning Commission and City Council in order to revise the organization and contents of the zoning and subdivision chapters. The project has been broken down into four phases: Phase 1 – Project Kick Off and Understanding [COMPLETE] Phase 2 – Diagnose the Current Ordinances and Frame Approach [COMPLETE] Phase 3 – Prepare Draft Codes Work Session #1 – Zoning Districts and Uses [COMPLETE] Work Session #2 – General Development Standards and Provisions [WE ARE HERE] Work Session #3 – Development Procedures and Subdivision Regulations Phase 4 – Final Ordinance Adoption and Implementation Each work session with the Planning Commission will be focused on a handful of topics. The City Council will be briefed after each meeting on the discussion and recommendations of the Planning Commission. A web page is being developed and targeted stakeholder groups will be involved throughout the year as needed to provide input on various topics. Consideration and adoption of the new code is anticipated for late fall of 2025. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 2 WORK SESSION TOPICS At the first work session, the Planning Commission provided feedback on the City’s zoning districts, district purpose statements, housing types, and lot and site standards for residential uses. The draft zoning text for these topics is attached to this memo. There are two broad topics and several sub-topics that will be discussed at the second work session: • Nonresidential and Mixed Use Districts o Lot and Site Standards (District Requirements) o Principal and Accessory Use Tables (Land Use Charts) • Development Standards o Parking o Signage o Landscaping o Exterior Storage (Commercial) o Outdoor Lighting Nonresidential and Mixed Use Districts Lot and Site Standards Currently, most lot and site standards are contained within one large District Requirements chart. The first work session examined the standards for residential uses and recommended ways in which this table could be simplified. HKGi has the following recommendations related to this section of code for nonresidential and mixed use districts: 1. Both the Business Park (former B-4) and Gateway Business zoning districts distinguish between “Mixed Use Project or Multiple Occupancy Center” and “Single Use Project or Free Standing Building” uses. This is not a typical distinction in a district requirements chart and we are struggling to understand the purpose. Our recommendation is to simplify these districts and remove the callouts to these two types of development. 2. Given the simplification of number 1 above, we are recommending the minimum lot sizes for the BP and GB districts be reduced. Currently, the B-4 district requires 5 acres for mixed use / multiple occupancy buildings and 2 acres for single use / free standing buildings. Of the nine properties in this district, none of them meet the 5 acres minimum (even though most are multi-tenant buildings). Only five are greater than 2 acres. Keeping the minimum lot sizes as they are currently stated makes each lot nonconforming. In the GB district, minimum lot sizes of 20 acres (mixed use / multiple occupancy buildings), 10 acres (single use / free standing buildings), and 5 acres (other nonresidential uses) are required. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 3 Of the ten developed lots, only one is more than 20 acres. Two of the remaining nine are more than 10 acres. Again, keeping the current minimum requirements creates nonconforming lots. 3. Looking at site standards, many of the nonresidential front yard setbacks require 40 to 50 feet. This is on the large side for most communities we work with. At a minimum, reducing the front yard setback in the Mixed Use (former B-2) district below 50 feet would help establish a more inviting pedestrian experience as redevelopment occurs. If any front yard setbacks are revised, the corner side yard setback should be reduced accordingly to match it. The MU corner side yard setback is already set at 20 feet. 4. In most nonresidential districts, height is limited to 35 feet. This is already being exceeded in the I-1 district (Boston Scientific) and the INST district (at both Bethel and Northwestern). It may be appropriate to increase the maximum height in these two districts. 5. The maximum lot coverage (for structures) is set unusually low in the Business Park district at 25%. In fact, it appears the majority of the current lots have coverage closer to 40%, making them nonconforming. This current percentage should be increased. 6. Relatedly, the required amount of landscaped area in the BP and CC districts is quite low at 25% and 20% respectively. A low maximum lot coverage for structures combined with a low minimum landscape area may encourage extensive surface parking lots. Adjusting these two requirements in a coordinated fashion would help reduce the chances of this happening and encourage the right amount of landscaping in targeted districts. Barring indications that other lot or site standards need to be addressed, the majority of the requirements have been left as they are. A second set of draft tables for lot and site standards are included with this memo as a starting point for discussion. Principal and Accessory Use Tables Examination of the current Land Use Chart has two parts. The first is to look closely at which uses are called out in the chart and evaluate in which districts they are allowed to locate. The second part is to determine how they are allowed (by-right, permitted with standards, conditional, etc.). HKGi began the revision of a principal use table by grouping uses into categories such as Residential; Public, Social & Institutional; Commercial, etc., and then by sub-categories such as Household Living, Group Living, Lodging, Retail Sales & Services, etc. This helps a user navigate the table more quickly. Second, where possible HKGi revised the list of uses, sometimes consolidating similar uses into a more general line item and sometimes suggesting the addition of new uses that are missing. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 4 Third, for each use it was determined which zoning district was the correct “fit” given the history of zoning in Arden Hills as well as the updated purpose statements for the zoning district. In some cases, uses did not seem appropriate for a given district. In other, a use seemed to align with the intent of the district. Fourth, the way in which a use is allowed was revisited. HKGi is advancing a first draft of use permissions – prohibited, permitted, permitted with standards, and conditional. Finally, a shorter table of accessory uses was prepared as a complement to the principal use table. The full tables can be found in the attachments. New or modified language is shown in RED. A red X means the permission for that use in that district is suggested to be removed. A BLUE notation with a strikethrough indicates where a permission was changed. A few specific comments or questions about the use tables are noted below: 1. The way in which the current CC district was described allowed for a wide range of uses – from residential to funeral home to school to restaurant to fitness clubs. This may have been appropriate when the district was envisioned as a mixed use community center, but with the current focus on government services the types of uses allowed has been significantly reduced. 2. We recommend removing multifamily as a use from the GB district. If they City wants to support a multifamily development south of Round Lake a better approach would be to rezone the parcel(s) appropriately. 3. We recommend splitting Automotive Service Stations into Major and Minor in order to restrict more impactful activities from less intense districts such as the MU district. Similarly, dividing Retail Sales and Services between Large and Small would allow for more targeted placement of commercial activities. 4. A few new uses are included for consideration: Liquor Store, Animal Veterinary Clinic, Off0site Service Business, Construction Contractor Yard, Personal Storage Facility, and Outdoor Commercial Recreation (as a principal use). 5. A number of specific principal uses stand out and raise questions: a. Boarding House is listed as a current use. Should this be retained? If so, should it be allowed in the R-4 and MU districts? b. Hospitals are listed in the use table but not allowed in any districts. Which districts, if any, should allow hospitals? GB and I-FLEX? c. The current code makes provisions for Micro Breweries and Micro Distilleries, but does not allow Breweries or Distilleries. Should they be allowed? d. Nursery seems to be incorrectly allowed in all residential districts. Allow in I-FLEX? e. Pawn Shops are strangely only allowed in the POS district. That seems inappropriate – where should they be allowed? I-FLEX? f. Public Use is currently allowed by conditional use in almost all districts, yet public facilities are only located in the CC district as well as the MU district (future fire station). Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 5 We recommend making this use permitted in the nonresidential districts and allowing it in the CD district to accommodate existing uses. g. There is no explicit Park / Open Space use listed. We recommend adding this and allow it by right in the POS district. 6. A handful of changes are recommended for accessory uses: a. Remove some uses that are listed as accessory but are really principal uses: Business Services; Clubs, Sports and Fitness; Personal Services. A Dog Run is an accessory use that does not need to be called out but can be handled similar to other accessory structures/uses such as sheds, gazebos, play equipment, etc. b. We recommend allowing Drive-up Windows and Solar Energy Systems in additional districts. c. Because the I-2 district was eliminated, we recommend allowing Exterior Storage in the I-1 as permitted with standards. This would accommodate the existing lumberyard. QUESTIONS FOR DISCUSSION • Are there questions or concerns around any of the recommended lot and site standard changes? • Are there other changes to the principal and accessory use tables that should be considered? Development Standards As part of this code update, reviewing the City’s current development standards provides the opportunity to assess whether or not there are topics that need further regulation or increased flexibility. Beyond general reformatting and clarification edits, HKGi has identified key topics that necessitate a policy discussion for the updates. These topics include: Parking, Signage, Landscaping, Non-residential Exterior Storage, and Outdoor Lighting. Background on the existing provisions will be provided, with a recommended approach for the update. Commissioners’ feedback on the proposed approach and discussion of any other topics of concern are welcome for consideration in providing direction on the code update. Parking • Minimum Parking Requirements Regulating minimum parking requirements ensures that all uses provide sufficient on-site/off- street parking to mitigate traffic and circulation concerns. The current minimum parking requirements table has been identified as a necessary element to update for this topic, due to inconsistencies with the use table. There are also some concerns that certain uses may be required to provide more parking than necessary. While there is no perfect calculation to determine the appropriate number of stalls to require and the requirements can be highly customizable, it is beneficial to understand the current parking demands for different uses. During the meeting, we will explore adjusting some of the use terminology to be more generalized and consistent with the use table for easier administration of the code. The Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 6 minimum number of parking stalls required will also be reviewed to be updated with more current parking demands and best practices. In preparation, please consider your experience and observations in the community regarding the amount of parking required versus what is actually utilized for certain uses. See the existing and proposed parking tables below. Existing Parking Requirements Use Required No. of Spaces Bingo Halls 1 for each 1.5 max. seating capacity Bowling Alleys 5 for each lane plus spaces for related uses Business & Professional Office 1 for each 250 sq. ft. of gross floor area Call Center 1 for each 150 sq. ft. of gross floor area Churches, Theaters, Auditoriums, Mortuaries, and Other Places of Assembly 1 for every 3 seats (based on design capacity) Clinics 1 for each doctor or dentist plus 1 for each nurse, technician, or professional and 1 for each 200 sq. ft. of gross floor area Daycare, Nursery, and Pre-School Facility 1 for each teacher or employee plus 1 for each 5 individuals receiving care (design capacity) Dwelling, single and two-family 2 for each dwelling unit Dwelling, multiple family 1.1 per efficiency and 1 bedroom dwelling units; 2 for each 2+ bedroom dwelling units Inside Motor vehicle Leasing or Sales 1 for each 250 sq. ft. of gross floor area used for showrooms, sales, and offices Motels/Hotels 1 for each employee plus 1 for each unit Multiple Occupancy Structure 1 for each space required for each separate use Other Business and Industry 1 for each employee on major shift plus 1 for each vehicle used in conducting the business or 1 for each 1,000 sq. ft. of floor area, whichever is greater Recreation Facility 1 for each 1.5 persons at design capacity Residential Facility or Group Home 1 for every 4 residents plus 1 for each employee on major shift plus 1 for each on-call medical professional Restaurants, Bars 1 for every 2 seats Restaurant, Fast Food 15 stacking spaces for each customer pickup window plus 1 for each 2 seats Retail Sales 1 for each 150 sq. ft. of gross retail sales floor space Schools, Elementary, and Middle School 1 for each staff member plus 3 per classroom Schools, Secondary 1 for each school employee plus one space per 4 students Service Station 3 for each enclosed bay plus 1 for each employee on peak work shift Uses Not Specifically Noted Including Public Uses As determined by City Council after recommendation by Planning Commission.

Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 8 • Electric Vehicle (EV) Standards Electric vehicles are an emerging transportation technology that has been driving demand for more charging stations available to the public in recent years. Many cities are exploring incorporating standards into their codes to allow or require developments to provide EV charging stations. There are a range of options for communities to explore when adding these standards to their code. The spectrum typically starts with discretionary standards that generally allow EV chargers with basic parameters. It can then increase to requiring certain types of uses to be EV ready, which means requiring the installation of the electrical infrastructure for the eventual EV charging station to be installed. The more prescriptive regulations can directly lead to requiring the installation of EV charging stations; these standards often vary depending on the scale of the use. It is also helpful to understand that there are different charger levels demonstrated by the following graphic: trigger Since Arden Hills is starting from scratch, HKGi recommends a combination approach for residential and nonresidential uses that combines requirements for some EV charging stations to be installed with those only requiring uses to be EV ready. The initial draft language is proposed below. We will look to the Planning Commission to help determine if this is the appropriate level of intervention or if there is a desire to increase or scale back the requirements. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 9 Subd. 1 Electric Vehicle Charging Stations (EVCS) A. Electric vehicle charging stations are allowed in all zoning districts. B. All new single-unit or two-unit dwelling developments shall be provided with an EV ready Level 1 or higher wall plug for charging an electric vehicle. C. Minimum number of EVCS required. 1. For all multi-unit dwellings and nonresidential developments with new parking areas, and existing parking areas proposed to be expanded or reconstructed by more than 25%, the following are required to be provided: a. 5% of the parking area shall be EV ready; b. At least two level one or higher EVCS shall be installed; plus c. At least one accessible parking stall with access to an EVCS level one or higher. D. Accessible Parking Spaces. An EVCS will be considered accessible if it can serve as an accessible parking space as defined and required by the Americans with Disabilities Act (ADA). It is not necessary to designate the EVCS exclusively for the use of vehicles parked in the accessible parking space and it shall not count toward required ADA parking requirements. E. Reductions to EVCS requirements. 1. This number may be reduced by the City if proof can be provided that: a. The cost of installing the EVCS required by this Chapter exceeds five percent of the total project cost; or b. It is not feasible to provide sufficient electrical capacity at the site to power the EVCS. F. EVCS shall be designed and installed to meet the following minimum design requirements: 1. EVCS must be securely installed and protected within any of the following methods: a. A parking island; mounted to an adjacent pedestal, wall, or similar structure. b. Free standing EVCS shall be protected by bollards, structures, or curb. 2. EVCS must be located adjacent to the designated parking spaces in a garage or parking lot, as long as the devices do not encroach into the required dimensions of the parking space (length, width, and height clearances). 3. EVCS shall be setback at least three feet from any property line. However, upon written request from the property owner, the City may reduce this setback requirement pursuant to a finding of necessity and public convenience. 4. Where EVCS is located within three feet of the public right-of-way, the location must be approved by the City. 5. EVCS shall be designed and located so as not impede pedestrian walkways or vehicle circulation. 6. EVCS cords must be retractable or have the ability to be hung sufficiently above the ground when not in use. The cords shall not extend across sidewalks or trails during charging. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 10 7. EVCS must be installed per manufacturer specification, with contact information provided on each charger for reporting or maintenance concerns. 8. EVCS must comply with all applicable building codes and relevant ADA requirements. 9. Any EVCS in a single-unit or two-unit dwelling shall be stored on the exterior wall of the home, in the garage, or on a freestanding pole with footings within the property adjacent to the parking area. 10. EVCS shall be maintained in good condition and functional at all times, including free of any rust. When an EVSE is not operational for 30 consecutive days, it shall be removed or have a repair plan approved by the City through the procedures in Section 1370. Signage The Sign Code was updated fairly recently to comply with the Supreme Court ruling in Reed vs. Town of Gilbert (2015) acknowledging that governments cannot regulate sign content because it's protected as free speech under the First Amendment. The Sign Code is currently separate from the Zoning Code; through this code update it is proposed to be included in the Development Standards chapter for easier administration. HKGi suggests changes to allow more signage for businesses, simplify the City's review and permitting process, and make permanent sign regulations more flexible. We'll discuss the existing sign table to explore adjusting standards for nonresidential districts, including an overview of signage size, type, height, and illumination. We'll also briefly discuss improvements to the sign area calculation and propose to allow more dynamic display signs while ensuring the standards are appropriate and consistent. The Planning Commission should review the attached existing sign table and consider what signage looks like in other communities that could be utilized as an example to further explore. Landscaping Ensuring sufficient landscaping requirements can improve the character and natural environment in a community. However, there are times when landscaping requirements are too restrictive and create unnecessary barriers to development. HKGi has observed that this section of the code could use further review on the minimum tree planting requirements. Currently the tree planting requirements are related to the gross square footage of a building. For larger buildings with a large footprint and/or multiple floors this can require overplanting of a lot, resulting in challenges to find space for all of the required vegetation and ultimately impacting the health of the trees. Alternative approaches base tree requirements on the amount of area available to plant and use a ratio of number of trees to square feet of landscaped area to establish the appropriate number for the site. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 11 Exterior Storage (Commercial) It is common for nonresidential properties to have exterior storage concerns, whether it’s an excessive amount or an unsightly appearance of vehicles and other materials stored on the property. The current code language is very general and vague, making it difficult for staff to administer and enforce: • Vehicles, including but not limited to cars, trucks, buses and RV's parked and/or stored in public view for more than a period of seven (7) days shall be prohibited unless allowed by the permitted business or industrial use, except as regulated in Section 1325.12. • Inoperable and Unlicensed Vehicles. Exterior storage of passenger vehicles, commercial vehicles, recreational vehicles, trucks, boats and watercraft that are in an inoperable condition or are unlicensed shall not be parked outdoors in the city for a period exceeding seven days. During the meeting we will discuss the direction that HKGi recommends pursuing for the proposed elements as an approach to increasing these standards: • Setting a maximum percentage of the property to be allocated to accessory storage. • Regulating overnight parking of various types of vehicles by differentiating between company vehicles, customer vehicles, scrap vehicles, semitrailers, etc. • Requiring the location of accessory storage and certain vehicles in the side or rear yard, including provisions for what is allowed if the property is located on a corner lot. • Requiring increased screening provisions for accessory storage or vehicles from public view. • Limiting the height of the accessory storage or vehicles with additional toppers. Outdoor Lighting Arden Hills lighting standards are very brief and generally lack detail. HKGi believes they could be dialed up to ensure that lighting is not impacting health, safety, and welfare. Currently the code regulates illumination as: • Any light or combination of lights shall not cast light that exceeds a meter reading of one foot candle on the travel lanes of adjoining public streets or 0.4 foot candles on adjoining residential property. HKGi recommends including provisions that state that lighting shall not impact visibility and also prohibit flashing, moving, or intermittent lighting which could be hazardous. Another recommendation is to reduce the 0.4 foot candle allowance at the property line to zero to ensure no lighting is disrupting adjacent properties. In addition, dynamic displays are currently only allowed on drive-thru menu signs. This restriction is out of touch with other metro communities and should be expanded to allow reasonable use of dynamic displays in nonresidential districts. QUESTIONS FOR DISCUSSION • Are there any concerns with the proposed approaches for the identified topics? Consider if some topics are too restrictive or too flexible. Planning Commission Meeting – Zoning and Subdivision Ordinance Revisions – Work Session #2 – April 9, 2025 12 • Are there any development standards or aspects of the identified topics that should be further analyzed or are in need of updates? • Aside from the topics identified, are you seeing any other concerns in the community that could be addressed through development standards? What about regulations around Fences/Screening? NEXT STEPS Following Work Session #2, HKGi will draft revisions to the zoning code text and review the proposed changes with staff. A summary of the session will be forwarded to the City Council. Work Session #3 will focus on use specific standards as well as recommended changes to the general procedures and the subdivision code. ATTACHMENTS • DRAFT Zoning Text from Work Session #1 • DRAFT Lot Standards Table • DRAFT Site Standards Table • DRAFT Principal Use Table • DRAFT Accessory Use Table • Existing Sign Table Page 1 of 3 AGENDA ITEM – 3F MEMORANDUM DATE: May 12, 2025 TO: Honorable Mayor and City Councilmembers FROM: Jessica Jagoe, City Administrator SUBJECT: Zoning Code Update Discussion Budgeted Amount: Actual Amount: Funding Source: N/A N/A N/A Council Should Consider Council should discuss and provide direction to staff on zoning code updates within HKGi Summary of Work Session #2 memo and recommendations brought forward for consideration. Background At the April 9th Planning Commission meeting, the consultants from HKGi presented their second memo for the zoning and subdivision ordinance updates which included discussion topics for non-residential districts and development standards such as parking, signage, landscaping, exterior storage, and outdoor lighting. Included with this memo as Attachment A is the summary memo prepared by HKGi that provides comments and recommendations for City Council consideration. This process is currently in Phase 3, which is when the technical updating and drafting of regulations occurs. As part of the tasks in this phase, the consultants will prepare minor code update language for the Planning Commission and City Council. Based on the Council feedback, HKGi will also start in this phase to conduct community engagement, including online mapping tools, creation of a project page on City’s website, community in-person events, and/or other outreach tools. Page 2 of 3 As a next step, staff is looking for direction from the City Council on the discussion items that will then be shared with HKGi. This feedback will be shared with the consultants and incorporated into the draft ordinance language that is being prepared. Items for discussion include consideration of the following: • Lot Standards – For the Business Park (former B-4) and Gateway Business zoning districts and recommended simplifying the minimum lot sizes that were associated with those uses (Attachment B). • Site Standards - HKGi is recommending reducing front yard setbacks in Mixed Use (former B-2), Corridor Business (former B-3) and Business Park (former B-4) to create pedestrian and bicycle-friendly environments. In addition, there are suggested standards for lot coverage and landscape area to align with off-street parking requirements and balance surface parking needs with landscaping (Attachment C). • Principal and Accessory Use Tables – HKGi has prepared the proposed principal and accessory use tables for non-residential zoning districts. The consultants have made recommendations on revisions for naming of uses and optional additional non-residential uses to consider, as well as those uses for discussion of transitioning to Permitted with Standards. The consultants are not proposing to remove Conditional Uses altogether, but this would allow the City to apply the same conditions and would remove some barriers to development (i.e. application review time and expense). o Permitted Use has few additional standards beyond the usual lot and site requirements such as lot size, yard setbacks, height, impervious coverage, etc. o Conditional Use requires a public hearing to ensure that any potential impacts to surrounding properties are mitigated through conditions that are tailored to the specific use and circumstances. Page 3 of 3 o Permitted with Standards do not require a public hearing but do have additional performance requirements listed in code that must be evaluated by Planning staff to ensure they are being met before a proposed project may apply for a building permit. • Development Standards - HKGi reviewed existing ordinance language and discussed with the Planning Commission several other development standards for parking, signage, landscaping, exterior storage, and outdoor lighting which are summarized in their memo to the City Council. In June, HKGi will have a third work session with the Planning Commission focused on use specific standards, the subdivision code, and various procedures for land use applications.

Background Per Council’s adopted policy on agenda setting, please find the proposed agenda below for the upcoming meeting. June 30th Special Work Session • Chickens Ordinance Discussion • Flock Cameras Discussion July 14th Special Work Session • 2026-2030 CIP Discussion • RCC/TCAAP Discussion (not time sensitive) • Agenda Planning (time sensitive) July28th Special Work Session • 2026-2030 CIP Discussion • Public Works Design Manual – Tree Species • RCC/TCAAP Discussion (not time sensitive) • Agenda Planning (time sensitive) Attachment A is the list of topics that have yet to be discussed by Council and the 2025 ranking of priority topics as distributed to the Council at the January 13th Work Session. Staff will begin to work the higher priority items into upcoming Work Sessions sooner while putting the lower priority items to later discussions. Please note, this does not reflect all items at Work Sessions as Page 2 of 2 Staff will have necessary items for discussion, such as, budget discussions, concept plan reviews, or Public Works projects that need timely direction. Council may want to discuss if any items need to be added to this list for future discussion or assign a future meeting for some of these items. This would need to be done by a majority consensus of Council. Below is a running list of things Staff brings forward to Work Session annually, in recent years, we have shifted away from bringing some items forward unless needed, such as, the Pavement Management Update from Public Works. Note, these timelines may shift year to year. Most items discussed at Work Sessions are one-off items that may require multiple meetings but are usually not reoccurring. • January o Legislative priorities • February o None • March o Initial guidance on next year’s Public Works projects • April o None • May o None • June o Follow up on next year’s Public Works projects • July o Capital improvement planning • August o Operating budgets • September o Operating budget and levy discussion • October o State of the City (if planned for early following year) • November o City-wide budget and fee schedule o Follow up on next year’s Public Works projects • December o Committee and commission appointments Budget Impact N/A Attachment Attachment A: Council Priorities Attachment B: Agenda Setting Policy Topic for Consideration Likely Responsible Dept.Total Average 75th Anniversary Discussion Planning Admin 14 2.8 Short-term Rental Ordinance CD/Admin 13 2.6 Rental Licensing Program CD/Admin 13 2.6 Code of Conduct Admin 13 2.6 Encroachment Discussion (2025)PW 13 2.6 Funding of Lake Johanna Boulevard Trail PW/Fin 12 2.4 Committee/Commission Liaison Role Policy Admin 12 2.4 Committee/Commission Goal Setting Admin 10 2 Volunteer Recognition (to Personnel first)Admin 10 2 Committee/Commission Membership Admin 10 2 EDA Membership Discussion CD/Admin 10 2 Keeping of Ducks and Review Chicken Ordinance CD/Admin 10 2 Buy Nothing Day/Clean Up Day Admin 10 2 Climate Action Plan Admin 8 1.6 Energy audit Admin 7 1.4 Community Survey Admin 7 1.4 EV Fleet Analysis PW 6 1.2 Approved Policy Discussion Admin 6 1.2 Added Items: January - March Meeting Schedule Feeding of Geese Accessory Dwelling Units Cannabis Discussion CITY OF ARDEN HILLS Agenda Setting Policy The purpose of this policy is to establish a method for agenda setting that allows for Council to review and have control over its agendas and decide as a Council how it wants items for consideration to be brought forward. For regular worksession agendas: • Prior to concluding each regularly scheduled worksession, the City Council shall review its next regularly scheduled worksession agenda and direct Staff on any changes. • Should an individual Councilmember want to raise an item for discussion at the next meeting or in the future, they would do so during this review period. The item would need at least one other Councilmember to agree to having the item considered for future discussion, and then Council, by majority, would direct to have it placed on a future agenda or not. • Staff will have flexibility to add or remove items to the worksession as needed to maintain operational efficacy. For regular City Council meeting agendas: • Agendas will be largely Staff driven based on approvals needed for normal operations. • Items coming from the City Council shall first be discussed at a worksession and can direct Staff at said worksession to bring items forward for formal approval if needed. • In rare instances, if a Councilmember brings forward an item that needs approval prior to going to a worksession, they may request the City Administrator add the item to the agenda. The City Administrator shall have the discretion to determine if the issue should be added or not, but Councilmembers will make every effort to having the item first discussed at a worksession. Special meetings and emergency meetings: • Special meetings and emergency meetings may still be called at the discretion of the Mayor or any two Councilmembers, and the members calling the meeting shall set the agenda.
