Prepared by: Bolton & Menk, Inc. SUNRISE DRIVE (MILL AND OVERLAY) 2023 Street Improvements (Sunrise Drive Mill and Overlay) ǀ 0N1.127995 Page 2 II. SUNRISE DRIVE (MILL AND OVERLAY) Background Sunrise Drive from Edgerton Street to 340’ south of the cul-de-sac 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, Sunrise Drive 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. Similar maintenance on City utility infrastructure ha s occurred on the streets since their construction. Existing Conditions 1. Streets Sunrise Drive is a bituminous roadway that measures 30 feet from face of curb to face of curb and 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. 2. Watermain The existing watermain is a 6-inch diameter ductile iron pipe. 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 detailed in this report. 3. Sanitary Sewer The existing sanitary system is an 8 -inch diameter vitrified clay pipe . City maintenance personnel have noted no known deficiencies within the existing sanitary system. Additionally, Bolton and Menk staff reviewed each sanitary sewer structure within the project area. The structures are precast and found to be in good to very 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 The existing stormwater infrastructure in the project area is confined to the southern side of Sunrise Drive at the bend where the water runs along the curb and makes it way to those two structures. It then runs west where it drains into a detention pond. The segments are composed of reinforced concrete pipe with a 12 -inch diameter. City maintenance personnel have noted that there are no known deficiencies with the storm sewer system. Bolton and Menk evaluated each of the storm sewer structures within the project area. The structures are precast and found to be in fair to good condition. Overall, the storm sewer system is expected to outlast the proposed pavement improvements. Proposed Improvements 1. Street Improvements Based upon the pavement age and d istresses, the proposed street improvement for this segment of Sunrise Drive is a 2” mill and overlay. A depiction of the proposed street and utility improvements is shown in Figure 2 in Appendix A. Current pavement distress patterns indicate surface-level wear but no significant deterioration of the roadway base. A mill and overlay is a cost-effective way to prolong
