The study, which evaluated the condition of all streets in town, set a recommended schedule of improvements including, seal coats, overlays, and reconstructions. Also considered in the study, were streets which were not yet serviced with City water main. Street improvement projects were proposed to coincide with those utility installations. The study proposed two seal coat projects, one in 2004 and the other scheduled for 2006. In 2004, the city seal coated most of the streets recommended for said improvements in that year. Remaining streets were seal coated in 2008. The study also laid out two street and water main improvement projects, one scheduled for 2004, and the other for 2009. In 2004 and 2009 the city completed street and utility improvement projects covering some of the streets designated for improvement by the study. However, due to budget constraints, the condition of some of the streets and other factors, several areas remain unimproved. For the most part the two projects have been administered in similar fashion. The costs of the street work has been assessed at a rate of around 25 to 30% of the actual costs with the exception of new amenities like curb and gutter, which were assessed at higher rates. In some areas, water main improvements were assessed at 100% of the costs. Where they were not, a connection charge equivalent to the assessment amount was established in order to recoup the costs of the installation. In the 2009 project, residents were offered the additional option of having the service line installed directly into their homes. Throughout this process, the City Council has maintained some form of ordinance requiring the hook -up to city water once it was placed in front of a home. However the deadline for connection has been extended on occasion. Streets not identified for improvements by the 2003 study, including those constructed since then are not evaluated in this report. They will be entered into the City's new "Thin Overlay Program" as outlined in the City's Pavement Management Plan Supplement, prepared by City Staff and dated February 8, 2011. City of Centerville Project No: 193801520 2013 Street and Utility Improvement Project J Stantec Page e 3 The streets evaluated in the 2003 study which remain unimproved have been separated into five sections for discussion purposes. These areas are shown in Figure 1 and are listed. in the table below.

Since then, the street has deteriorated, garnering complaints about its condition to city hall. Due to recent complaints and favorable bonding rates, city staff felt that this project should be considered for improvement in conjunction with the 2013 Street Improvements. The larger project may help to attract more bidders and a lower winning bid. Area A is part of the project studied under this report. Proposed improvements include: • Full Street Reconstruction • Installation of water main and services (including going into the homes at the option of the homeowner). In the early summer of 2012, Stantec, along with City Staff, did a thorough inspection of all streets identified for the study and their respective existing conditions. Based on this inspection weighed against cost and other factors, the streets are proposed for the following levels of repair. STREET IMPROVEMENTS - FULL RECONSTRUCTION OF THE STREET SECTION The streets in this area have demonstrated a lack of proper drainage and subbase material to withstand the high water table and freeze thaw cycle. Therefore, the proposed improvements include a full reconstruction of the street section. The new section will add significant depth of section with sand, fabric, draintile and gravel base (see Figure 4). Additional catch basins and storm sewer where it is both needed and reasonably feasible will also be included. Because these improvements will remove and replace curb and gutter and will extend water services to the property line, a significant amount of front -yard disturbance will be involved. Boulevards will be restored with sod and driveways will be replaced in -kind. The amount of sod and driveway replaced on each lot will depend on service locations and any changes in street grade which may be part of the final design to better fit the existing topography. City of Centerville Project No: 193801520 2013 Street and Utility Improvement Project J Stantec Page e 5 AREA B This area was eliminated from the 2009 project based on input from the public who wished to see the overall cost of the project reduced. These streets are being considered for improvements as part of the last remaining unimproved streets from the 2003 study which already have city water main. In the 2009 study, these streets were slated for full reconstruction. However due to the fact that a reconstruction of the road would trigger the need for costly rain gardens or other infiltration features, a more limited scope of improvement is being considered. Area B is proposed to be a part of the project studied under this report. Proposed improvements include: • Full bituminous removal and replacement • Spot repairs of curb and gutter • Limited draintile installation STREET IMPROVEMENTS - FULL BITUMINOUS REMOVAL AND REPLACEMENT Streets in this portion of the project will have the existing gravel section left in place along with the curb and gutter. The new section will consist of draintile, the existing gravel base and new bituminous (see Figure 4). Spot repairs to the curb and gutter as well as to the gravel base could be made as necessary. Draintile could be trenched in along the front edge of each of the curb lines to help maintain the integrity of the subbase. For the most part, curb and gutter in these segments is in good condition and will require only spot repairs. This means that little or no disturbance behind the curb will take place, keeping costs at a minimum. Part of the reason for the deterioration of these streets is often a lack of proper surface drainage. Therefore, the proposed improvements include additional catch basins and storm sewer where it is both needed and reasonably feasible. City of Centerville St an t eC Project No: 193801520 6 2013 Street t and Utility Improvement Project Page e 6 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Future Improvements AREA C Although the 2003 study's Pavement Condition Index (PCI) scoring system had this area scoring low, improvements were not proposed due to the possibility of this area being redeveloped as part of the City's Downtown Redevelopment Plan. The city will need to decide whether or not investing in street improvements and water main installation in this area should be pursued given the current development market and the condition of the existing streets. If improvements are made, they should be designed in accordance with the Downtown Redevelopment Comprehensive Infrastructure Plan. AREA D Area D consists of Mound Trail and Lavalle Drive. Mound Trail is a city street with a rural cross section. This unique feature allows water main to be installed in the boulevard without disturbing the street. Much of Mount Trail already has water main. However, not all of the homes in this area have hooked to the main. The remaining (western) portion of Mound Trail is still unserved by water main. This main should be kept in mind when planning future improvements and could be done in conjunction with another project at some point in the future. This main would also service several buildings in the County park. The main could be constructed as part of a negotiated deal with the county. Lavalle Drive is a private roadway. Homes in this area are not served with city water. Despite the private road status, the city should look to service this area like any other. AREA E This development was built without water main and was included in the proposed 2009 project. However, it was removed for a number of reasons, including the difficulty install water main without a complete reconstruction of the narrow streets. Additionally, the lot sizes and home values in the area may make it difficult to keep special assessments viable. The city is looking for grant money to subsidize these improvements. Additionally, water main installation methods and routes are being explored to avoid disturbing the street. Improvements in this area are probably best pursued when g rant monies are available. City of Centerville Project No: 193801520 2013 Street and Utility Improvement Project J Stantec Page e 7 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Storm Sewer Improvements The existing storm sewer system has been reviewed by City and Stantec staff. Please refer to Figures X and X for a graphic depiction of the layout of the existing system and the proposed improvements. PROPOSED PIPE INSTALLATIONS There are a number of places where it has been determined that additional pipe and storm sewer structures are needed. These improvements will help surface drainage which will in -turn add to the durability of the street surface. Subsurface drainage improvements are also proposed with the use of draintile either in front of the curb, if it is being salvaged, or behind the curb in areas of full street reconstruction. STORM SEWER CROSSING ISSUES The City of Centerville has been experiencing some serious problems due to heaving of fat clays and other moisture laden subgrade soils around existing storm sewer crossings. This annual heaving and settling from freeze -thaw cycles produces uneven roadways and often leads to deteriorated pavements. It is recommended that all storm sewer crossings be excavated and restored with suitable material in order to reduce movement of the future roadway. Figure X illustrates the cross section of these proposed improvements. PROPOSED STORM WATER MANAGEMENT The proposed project area lies within the Rice Creek Watershed District (RCWD). Therefore, the District will have permit authority over the project and the storm water management within the project. In order to meet the infiltration requirements of the District, it will be necessary to install infiltration basins (rain gardens), swales, or other Best Management Practices (BMPs) throughout Area A. In the attached Appendix A, potential BMP sites are identified (Figures X). It is important to note that these locations were chosen based on existing topography. Locations will need to be adjusted as more information is collected. Once engineered locations are proposed, Stantec and City Staff will conduct one -on -one meetings with any affected residents. Theses meetings will supplement the design process by allowing residents to provide feedback as to their level of interest in the program and in eventual maintenance of the BMP. An exact location and design of the BMP can be concluded based on this feedback. While some BMPs will be able to be constructed within the existing right -of -way and adjacent easements, others will require additional easements. A cross section of proposed infiltration basins is shown in Figure X. City of Centerville Project No: 193 80 8 Stantec 2013 Street and Utility Improvement Project �%+ Page 8 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Sanitary Sewer Improvements Since the City has chosen to make an investment in its streets, it is important that everything underneath those streets be checked to ensure the street investment is not compromised by the future need to repair infrastructure below. The existing conditions of the sanitary sewer system were evaluated through the examination of the City's regularly scheduled sewer televising program. The reports produced from these video inspections were analyzed for deficiencies including mineral deposits, open or offset joints, sagged, cracked, or fractured pipe. Recommendations for the rehabilitation of the sanitary sewer system are included below. Repairs are proposed based on the severity of the problem and the need for that problem to be fixed via open -cut methods. Issues which could be repaired with in -line technology have not been included since their repair can be completed at any time, without disturbing the pavement. REPLACING AND REPAIRING PIPE A short section of damaged pipe was identified on Peterson Trail, just north of Houle Circle. This pipe should be repaired by city crews prior to the construction of this project. City of Centerville Project No: 193801520 2013 Street and Utility Improvement Project , Stantec Page e 9 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Water Main improvements Extending water main to areas without municipal water service has been a stated goal of the city for many years. With this in mind, common sense dictates that when the street is disturbed for resurfacing or more extensive improvements, the opportunity to install water main should not be overlooked. WATER MAIN EXTENSIONS Areas to the north of Main Street, in this project area, already have city water service, the Center Street area does not. The proposed improvements detailed in this report include the installation of an 8 -inch water main on Center Street, from Dupre Road to 20th Avenue (CSAH 54). A 6 -inch water main would be extended up each cul -de -sac. WATER SERVICE STUB INSTALLATION Each home along the new mains will have a service line extended to the right -of -way, terminated with a curb stop. This will be installed regardless of whether or not the homeowner chooses to hook to city water with the project. WATER SERVICE CONNECTION TO HOME It is recommended that homeowners have the option to hook to the City's water system in conjunction with the proposed street improvements. Providing this option would be prudent as this would confine the mess of construction to one year and would ease enforcement of the hook up policy in 2017. The City's residents would have two options regarding water services. Option one would be to have the City's contractor install the water service from the curb stop (property line) into their home or option two would be to hire their own contractor to do the same thing. If the resident chose option one, the City would allow the cost of the connection to be financed along with the assessment and the service would be directionally drilled into the homeowner's basement. This option would minimize restoration costs, minimize construction costs by bidding all at once and allow the homeowner to have a "turn -key" project. If the resident chooses this option, a right -of -entry waiver must be signed allowing the contractor access to the resident's property. Additionally, a waiver of assessment appeal would have to be signed in order for the City to avoid further issues regarding the matter. If the resident were to choose option two, the City would just require that they meet the 2017 connection deadline. The homes in this area are serviced by individual wells. As part of the 2009 Street and Utility Project, those homeowners electing to have the water service installed into their home as part of project were also given the option to have the contractor seal their well at the same time. If the homeowner would like to keep the well operational, it may only be used for irrigation or an outdoor hose -bib connection. City of Centerville 2013 Street and Utility Improvement Project � Project No: 193801520 .�+' J�QI'�t� Page 10 BOLT REPLACEMENT In the late nineties, the City began requiring all water main fittings to be installed with corrosion resistant bolts. These fittings include valves, bends, tees, and hydrants among others. This policy was invoked due to several bolt failures which appeared to be caused by corroded bolts. These bolts were likely compromised by cathodic conditions in the City's predominately clayey soils. Water main, installed before the corrosion resistant bolts were specified, exists below streets proposed to be rehabilitated with this project. City staff has or will coordinate the replacement of these bolts prior to construction of this project. I I City of Centerville Project No: 193801520 2013 Street and Utility Improvement Project j Stantec Page 11 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Pathway and Sidewalk Improvements For the area of the project, north of Main Street, sidewalks do not currently exist. There does not appear to be compelling reasons to install sidewalks in this area. Fox Run and Houle Circle are dead ends, with little traffic. Hayfield Road has parallel pedestrian routes on 73rd St. and Main St. Peterson Trail also has alternative, parallel routes on Mill Rd. and Brian Drive. Center Street also Tacks an off - street pedestrian route. In this case, the connection of the new trail along 20th Ave. (CSAH 54) to the sidewalk on Dupre, which continues through Pheasant Marsh, out to Centerville. Road (CSAH 21) and to the City's main park makes some sense from a city -wide connectivity perspective. Since Center Street performs as a collector street, sidewalks would be desirable from a safety perspective. However, the addition of a sidewalk is costly, unpopular with area residents (based on feedback from recent open houses and from comments received prior to the 2009 project) and limits the placement of rain gardens. The city will need to examine this issues and make a decision as to whether or not to include these improvements as part of the project. City of Centerville Ic� Project No: 193801520 2013 Street and Utility Improvement Project Stantec Page a 12 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Lift Station #3 It has been proposed that Centerville's lift station number three (LS #3) be eliminated and a new gravity sanitary line be run from the lift station to lift station number four. A survey loop was run between the two lift stations, confirming this is physically possible. EXISTING CONDITIONS Currently, LS #3 is operated and maintained by Centerville's public works staff. The lift station was installed in 1987 and the pumps were replaced on the station in 1997 indicating a 10 year life span for these pumps. This would lead us to the assumption that the existing pumps are likely nearing the end of their useful life. The staff is spending approximately one hour of time per week at the lift station for maintenance needs. PROPOSED IMPROVEMENTS Flow entering LS #3 would be re- routed down Center Street to the east. This would require re- hooking services along the way. The estimated project cost is presented in Table 3. The proposed route is shown on Figure X.

The net cost savings in maintenance for Option 2 is $7,730. This gives us a payback period of roughly 13.7 years. The payback period itself is short enough to justify the improvements. However, with the additional reliability of the system, which is difficult to quantify, gained through the improvements, we would recommend installing the new gravity sewer to eliminate LS #3.

City of Centerville Project No: 193801520 2013 Street and Utility Improvement Project J+ StanteC Page 15 CITY OF CENTERVILLE - 2013 STREET AND UTILITY IMPROVEMENT PROJECT Assessments Special assessment law requires that assessments not exceed the benefit afforded to adjoining properties by the project improvements. One way of estimating this benefit is to have a qualified real estate appraiser examine a number of properties throughout the project area and give an opinion of the special benefit the project would produce. If bonding for the project, a minimum of 20% of the project costs must be specially assessed. It is our understanding that the City will or has hired an appraiser and is proposing assessments as follows: Full Reconstruction $3,500 - $4,200 /lot (assumes 90' lot) Estimated assessments $130,000 - $160,000 Full Bituminous Rem. & Replacement $2,000 - $2,600 /lot (assumes 90' lot) Estimated Assessments $116,000- $150,000 Per city policy and practice, an assessment rate will be calculated on a per foot basis, based on the numbers above. Then, the assessments will be figured on a front -foot basis for each individual lot. For side yards, 20% of the footage will be assessed in addition to the front yard footage. The city is proposing to assess street improvements only. Sewer and water work will be paid through the respective enterprise funds. The city has adopted a fee schedule for water hook -ups, with separate charges for those who have been assessed and those who have not.
