Prepared by: Bolton & Menk, Inc. SPRUCE STREET 2023 Street Improvements (Sunset Court, Sunrise Dr, Spruce St) ǀ 0N1.127995 Page 6 IV. SPRUCE STREET Background Spruce Street is an urban City-street that transitions into Ryan Drive which serves the Ryan Industrial Park. Annual average daily traffic (AADT) data for this road is unavailable but assumed to be less than 1,000 vehicles per day classifying it as a low-volume road. Refer to Figure 1 in Appendix A for a depiction of the project location. Historically, Spruce Street has received crack seal and sealcoat treatments to prolong the useful life of the existing pavement. Annual pavement patching has also occurred as needed. The utility infrastructure has been maintained on a routine basis. • Spruce Street was improved within the platted Ryan Drive Industrial Park in 2016 • A portion of Ryan Drive was rebuilt and raised in 2021 as a flood mitigation project by the Ramsey-Washington Metro Watershed District. This project also included the construction of a new box culvert to improve drainage underneath Ryan Drive. • The remaining portions of Ryan Drive were improved in 2022 with an added sanitary sewer forcemain, storm sewer improvements, and a 2” mill and overlay. Existing Conditions 1. Streets Spruce Street is a bituminous roadway with an average width of 30 feet from face of curb to face of curb and has concrete curb & gutter throughout. The existing pavement within the project area shows signs of age- related distress including cracking and potholing. 2. Watermain The existing watermain is a 12-inch diameter ductile iron pipe running south until it connects into the segment running parallel with South Owasso Boulevard. 3. Sanitary Sewer The existing sanitary sewer is served by Metropolitan Council running parallel with the road and consisting of 36-inch reinforced concrete pipe. 8-inch diameter ductile iron pipe extends from the Metropolitan Council line to serve #3065 and #3075. City maintenance personnel have noted no known deficiencies within the existing sanitary system. Additionally, Bolton and Menk staff reviewed the single sanitary sewer structure within the project area. The structure is precast and found to be in fair to good condition. Based on the age, material, and historical performance, the sanitary sewer system is anticipated to outlast the pavement improvements described in this report. 4. Storm Sewer There are storm sewer catchment areas at both the northern and southern project extents. The storm sewer, catch basins, and culverts near the north project extent have Exhibit 3 - Existing Spruce Street
