Prepared by: Bolton & Menk, Inc. SUNSET COURT 2023 Street Improvements (Sunset Court, Sunrise Dr, Spruce St) ǀ 0N1.127995 Page 2 II. SUNSET COURT Background Sunset Court is an urban residential street. 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. Over the years, Sunset Court has received crack seal and sealcoat treatments in an effort to prolong the life of the pavement. Annual pavement patching has also occurred as needed. The utility infrastructure has been maintained on a routine basis since construction. Existing Conditions 1. Streets Sunset Court is a bituminous roadway that measures 30 feet face of curb to face of curb. Sunset Court has surmountable concrete curb and gutter on the north and south sides. The pavement shows signs of wear and distress, including cracking and potholes, which are typical for a pavement of this age. Refer to Figure 2A in Appendix A for a depiction of the existing utility infrastructure. 2. Watermain The existing watermain is a 6-inch diameter ductile iron pipe (DIP) that extends west from Edgerton Street where it eventually loops along a side lot line to the Sunrise Drive cul-de-sac. The water system has performed well, and there are no known deficiencies with the system. Based on the age, type, and positive performance of the watermain, the useful life of the system is expected to outlast the pavement improvements described in this report. 3. Sanitary Sewer The existing sanitary sewer contains segments of 8” and 15” vitrified clay pipe (VCP), 60” reinforced concrete pipe (RCP), and 8” DIP. City maintenance staff have noted no known deficiencies with the sanitary sewer system. Bolton & Menk staff reviewed each of the sanitary sewer structures within the project area. The structures are precast concrete and in good to very good condition, but some minor improvements are recommended to ensure the system outlasts the pavement improvements proposed in this report. 4. Storm Sewer The existing storm sewer system is composed of reinforced concrete pipe (RCP) varying in size from 12-inch diameter to 21-inch diameter. Stormwater is conveyed to 5 catch basins along existing curb & gutter before traveling through the pipe network where it outlets to 3 different detention ponds. Bolton and Menk staff reviewed each of the storm sewer structures within the project area. The structures are precast and overall are in good condition but would need minor Exhibit 1 - Existing Sunset Court
