Staff is preparing a resolution ordering a feasibility study for the 2024 PMP Street and Utility <br />Improvements for consideration by the City Council at the March 13, 2023 Regular City Council <br />Meeting. The purpose of this memorandum is to provide a general description of the preliminary <br />scope, budget and schedule for the project and seek any direction the Council may wish to provide <br />as staff prepares the feasibility report and recommended special assessment roll. <br />Preliminary Scope of Work <br />Existing infrastructure conditions within the proposed project area are as follows: <br />• Streets <br />o Through City pavement management records, the latest structural project type for <br />the streets were: <br />■ 1994 Reconstruction: Keithson Dr. <br />■ 1997 Reconstruction: Royal Hills Dr., Arden Vista Ct., McClung Dr., <br />Colleen Ave., Colleen Cir., Norma Ave., and James Ave. <br />■ 2007 Reclamation: Briarknoll Cir., Briarknoll Dr., and Royal Ln. <br />o The typical life cycle of a road with a structural type project is 15-20 years, which <br />puts this area in the category for pavement rehabilitation. <br />o Current pavement condition ratings range from 20 to 45 out of a possible score of <br />100. The surface of the streets is in poor condition covered with an extensive <br />amount of cracking and delamination. These streets have seen an increase in needs <br />for pothole filling and patching, therefore increasing the cost to maintain. <br />o Core samples from the Pavement Forensic Report resulted in varied conditions from <br />good to poor, but ultimately a majority of the cores were showing signs of <br />deterioration. <br />o Pavement rehabilitation will likely consist of mill & overlay or full -depth <br />reclamation with a finished 4-inch thick pavement mat. <br />• Sanitary <br />o All of the sewer that was installed as part of the residential development consists of <br />8-inch PVC material. <br />o Televising reports provided by our Public Works Department indicates the pipe is <br />in good condition. <br />o Manhole castings and concrete rings are deteriorating and need repair. <br />o Sanitary services will be more closely reviewed during the feasibility study to <br />determine repairs for inflow and infiltration. <br />Page 2 of 5 <br />
