Prepared by: Bolton & Menk, Inc. PITRINA PARK TERRACE ASSOCIATION Allen Avenue Improvements ǀ N15.119846 Page 6 III. PITRINA PARK TERRACE ASSOCIATION BACKGROUND A series of five private culdesac streets were constructed as part of the Pitrina Park Terrace Association to serve the new townhomes. The culdesacs include Caroline Court, Sherry Court, Frattalone Lane, David Circle, and Pitrina Way. The five culdesacs’ street and utility infrastructure were constructed in 1998 as part of the Pitrina Park Terrace development. The City was asked by the homeowners association to evaluate the feasibility and costs associated with rehabilitating these culdesacs in conjunction with the City-led Allen Avenue Improvements. Because the culdesacs are private streets owned and are maintained by the homeowners association, the association is responsible for 100% of the street costs. As such, the association will need to review the findings of this feasibility report and decide whether to proceed with the improvements. If the association decides to proceed, it would need to enter into a special assessment agreement with the City. This agreement would outline the anticipated project costs and the association’s cost participation. EXISTING CONDITIONS 1. Streets The Pitrina Association culdesacs include five roads: Caroline Court, Sherry Court, Frattalone Lane, David Circle, and Pitrina Way. The bituminous pavement within the study area shows wear and distress due mostly to age, as indicated by the pavement oxidation, cracking, raveling, and potholes. A geotechnical investigation was performed by Braun Intertec which included two pavement cores. The associated report is not included with this Report but is available at City Hall. The soil borings indicated that the bituminous thickness ranges between 2.25 inches and 5.25 inches. The aggregate base thickness ranges between 12 inches and 24 inches. 2. Watermain Each of the culdesacs includes a 6-inch diameter ductile iron watermain lateral. Refer to Figure 2 in Appendix A for a depiction of the existing utility infrastructure. The water system has performed well and there are no known issues 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 Each of the culdesacs includes an 8-inch diameter PVC lateral. City maintenance personnel has noted that there are no known deficiencies with the sanitary sewer system. Bolton and Menk staff inspected each of the sanitary sewer structures within the project area. The structures are precast and in good to very good condition. Based on the age, material, and positive performance, the useful life of the sanitary system is expected to outlast the pavement improvements described in this report. 4. Storm Sewer The street drainage for each of the culdesacs flows north to catch basins at each of the curb radii with Allen Avenue. These catch basins are considered part of the Allen Avenue storm sewer network and no costs for work to these structures is being attributed to the Pitrina Association.
