BOLTON & MENK Real People. Real Solutions. July 15, 2024 Joe Feriancek, P.E. Assistant City Engineer City of Ramsey 7550 Sunwood Drive NW Ramsey, MN 55303 RE: Proposal for Design Services — Dickenson's Mississippi Estates — IP 25-04 Dear Mr. Feriancek: 7533 Sunwood Drive NW Suite 206 Ramsey, MN 55303-5119 Ph: (763) 433-2851 Fax: (763) 427-0833 Bolton- Men k.com We understand that the City is proposing to reconstruct the streets within the Dickenson's Mississippi Estates subdivision in 2025. UNDERSTANDING Based on communications with the City, we understand the following: The project will include improvements to Tungsten Street from Rivlyn Avenue to Riverdale Drive and also improvements to Rivlyn Avenue from the west cul-de-sac to east edge of the Dickenson's Mississippi Estates plat. Tungsten Street and Rivlyn Avenue are urban section roadways, including concrete curb and gutter, with a storm sewer system and an outlet to the Mississippi River. The properties along the roadways are serviced by municipal sewer and water. There is a need to replace the gate valves in the area, but the City is also considering replacing the existing watermain with new PVC C900. Because Tungsten Street serves adjacent commercial properties, consideration is being given to building it back to a 10-ton design section, and build Rivlyn Avenue with a typical City street section. The City is looking to address stormwater runoff from 6140 Hwy 10 (Lano) as part of this project. This will include analyzing the stormwater runoff and recommending a solution. In general, the issue is with runoff from the south end of Lano's property flowing onto 6151 Rivlyn Avenue. The City will contract separately for sanitary sewer televising and also for geotechnical exploration. The results and recommendations for each will be forwarded to us when available. A completed topographical survey will be completed for the project. We will also complete a drone flight to obtain aerial photography and provide elevation related information for the 6140 Hwy 10 (Lano) property. The cul-de-sac at the west end of Rivlyn Avenue is partially outside of City ROW. As part of the project we will explore options to gain right-of-way or potentially shorten the length of the cul-de-sac to keep the construction within the existing right of way. Bolton & Menk is an equal opportunity empbo er.
