Mr. Bruce Westby March 2, 2021 Page 3 EXHIBIT A relocations. Additional time for coordination has been included in the proposal for potential coordination with affected utilities. Environmental Impacts It is anticipated that wetland impacts will occur, and that permission to impact those wetlands will be required. Permits will be required under the Wetland Conservation Act (WCA) and for Section 404 of the Clean Water Act. The extent of permitting needed is dependent on the quantity of wetland impacts, but the preliminary discussions indicate that impacts will be minor. It is assumed that impacts will require wetland mitigation. To calculate wetland impacts and mitigation needs, SEH wetland scientists, led by Rebecca Beduhn, will conduct an on -site investigation of wetland boundaries and habitat. It is assumed that the wetlands within the project area are under the jurisdiction of City of Ramsey, Anoka County Soil and Water Conservation District, and the United States Army Corps of Engineers (USACE). Wetland delineations will be completed in accordance with USACE Engineers 1987 Manual and the Midwest Regional Supplement. All areas meeting wetland criteria will be identified and flagged in the field. Wetland boundaries will be mapped using a sub -meter accurate Global Positioning System. The location of the wetlands will be provided in electronic format for inclusion in project plans. SEH will prepare a wetland delineation report for review by the WCA LGU (City of Ramsey) and US Army Corps of Engineers for their review and approval. SEH will facilitate any review of the wetland boundaries. After completion of the wetland delineation, SEH will assist the project proposers with determining the project purpose and need and with the sequencing process for the permitting process. Sequencing is the requirement to identify opportunities to reduce impacts through alternatives analysis, avoidance, and minimization. Once these exercises have been completed, a Wetland Permit Application will be prepared. This application will identify the project, define the purpose and need, summarize sequencing and provide a wetland replacement plan. Signatures will be required from the project proposer responsible for compliance with the permit conditions. SEH will act as agent to allow representation in the process. Preliminary Water Main Design & Value Engineering It is important to note that the design of the water main is greatly dependent on existing utility locations and available right-of-way and/or easements. Our team will identify a design approach that best serves the City and its relations with Anoka County Highway Department. The design of the water main is anticipated to be a combination of open -cut installation and trenchless installation to limit impacts to Bunker Lake Boulevard and existing in -place utilities. Our team will analyze the costs of such proposed installations to determine which methods are the best economical and practical approach. Task 2: Final Design & Bid Documents Final Design After the preliminary layout of the proposed water main is complete, Justin will lead the team into final design of the proposed improvements to meet the deadline of bidding this project in July 2021. The chosen installation approach of the water main will be designed to meet the AWWA, MDH and City of Ramsey standards. This will include design of impacted infrastructure such as trails, pedestrian ramps, driveways, storm sewer, sanitary sewer, curbing and miscellaneous restoration items. Bidding Documents & Bidding SEH will prepare the project specifications and bidding package, and the project can be advertised once City Council approval of the plans has been completed. SEH's project manager and technical experts will be available throughout the bidding process for questions. We will attend the bid opening and analyze the bids in order to give a contract award recommendation to the City. SEH will provide all project base files to the City in AutoCAD Civil 3D as well as all digital plan sheets.
