Other than where specifically identified otherwise, the plan drawings will primarily be a two-dimensional design based on aerial photography. It is assumed that all streets and curbs will remain in their existing locations/elevations during the mill and overlay and reclamation operations. The project will only include spot replacements of the existing curb and gutter that inhibits proper drainage or is structurally deficient. Design will be conducted to meet or exceed RCWD permitting requirements for stormwater management and erosion control. Upon completion of final plans, we will submit all required information to RCWD for verification/approval. Our scope of services assumes the project will be designed such that the RCWD stormwater management trigger for a public linear project (less than one acre of new or reconstructed impervious – excluding mill/ overlay and reclamation methods) is a design constraint. We do not anticipate, nor does our scope of services include design of volume control, water quality, and rate control practices. Watershed standards are subject to change and potential changes to the rules should be considered during the design of this project. However, we cannot anticipate what these changes might entail and will have to scope our services based on the current standards and how we anticipate RCWD will view the proposed project work. Bolton & Menk will provide plan submittals at 60 and 90 percent for city review prior to submitting the final plans for bidding. We will provide specification submittals at 90 percent for city review, prior to submitting the final specifications for bidding. Three final paper copies and a PDF digital copy of the plans and specifications will be provided to the city for bidding. Using past bid information from the City of Arden Hills and other nearby metro communities—as well as current contractor pricing, overall city knowledge, local contractors, and site conditions, we will prepare an opinion of probable construction cost. Electronic and hard copies of the opinion of probable cost will be provided to the city and be used for bidding and assessment purposes. TASK 8: PERMITTING AND GRANT APPLICATIONS Our team will prepare permit applications, secure city signatures, and submit them to governing agencies for all required permits related to the project (permit fees will be paid for by the city and are not included in our proposed fees). It is assumed that the following general permits will be required: • MPCA Construction Stormwater permit • RCWD Erosion and Sediment Control Plan permit • WCA permits • MnDNR Public Waters Work permit • Ramsey County right-of-way permit Conference calls will be coordinated with governing agencies to discuss permit applications, if necessary. It is assumed that RCWD permits will not be required for stormwater management or activities associated with lake sediment removal. Additional specialty permits will also be required at the five storm outlet locations into Karth Lake, surrounding the trail and new stormwater pond project areas. Completion of a Level 2 wetland delineation is necessary to determine the exact limits of the wetlands in relativity to the proposed improvements. A certified wetland delineator will visit the site to delineate all aquatic resource boundaries within the designated areas. The delineation will include transects and sampling in the vicinity of those wetlands, placing 3-foot pin flags at the limits of any wetlands found. Our delineator will use a sub-meter GPS unit to accurately locate and map each point and prepare a written report of our findings. If it is determined that additional wetlands delineations are necessary, our team can provide additional scope of work for an additional fee at the hourly rates identified. Bolton & Menk will use the aquatic resource delineation to determine and prepare the appropriate permit application to account for any aquatic resource impacts proposed by the project. Preliminary review of the project activities suggests permanent wetland impacts will be avoided. Bolton & Menk will prepare a no-loss/ exemption application to account for any temporary aquatic resource impacts. This will include the MN Joint Application to the U.S. Army Corps of Engineers and Local Government Unit. The submittal of Work in Public Water permit to the MnDNR will also be required due to the activities proposed in Karth Lake. 13 2026 PMP STREET AND UTILITY IMPROVEMENTS | CITY OF ARDEN HILLSWorK Plan and Project aPProach EXHIBIT A
