Page 10 of 23 segment entered will include Name, Beginning Location, End Location, Length, Width, Year Constructed, ID numbers. k. Ensure all GIS data conforms to the following: WA State Plane Coordinates, North Zone, High Precision Ground Network, and US Feet. ESRI Coordinate System: NAD_1983_HARN_StatePlane_Washington_North_FIPS_4601_Feet. 2. Maintenance Strategy and Plan Establish suitable rehabilitation and preventive maintenance strategies, including life-cycle costs for various maintenance alternatives including appropriate treatments such as slurry seal, chip seal, overlay, and reconstruction. i. Develop a prioritized street rehabilitation project list that will result in the greatest net present value within the given short-term and long-term budget parameters. I. Incorporate feedback from city staff on project priorities and confirm assumptions and processes used for prioritization projects. This process may take multiple iterations of the project plan to incorporate staff comments. II. Conduct a field review with city staff of the streets included in the refined street rehabilitation project list to verify pavement condition and recommended rehabilitation treatments. III. Estimate costs for the recommended improvements in current year-dollars. IV. Provide a six (6)-year project list for 2024-2030. V. Deliver a maintenance plan with narrative, tabular data, and graphics for review by city staff and use by the program team for future years. The plan will document the decision process and evaluation criteria used to include and exclude projects leading to the final recommendations for pavement rehabilitation and preventative maintenance projects. B. ASSESSMENT AND PLAN RESULTS The Consultant will provide a detailed plan for an ongoing process of maintaining, upgrading, and operating pavement assets cost-effectively, based on a continuous physical inventory and condition assessment. The Consultant will provide: 1. Inventory Definition Typically, pavement management requires road inventory to be created and tied to an Asset Location Referencing System (ALRS). Road inventory includes road location using both coordinate and linear referencing systems, road width, road length and pavement type. 2. Condition Assessment Pavement conditions can be divided into structural and functional conditions with various condition variables. To measure such indices and provide data collection, the best available technology should be used to reduce costs. 3. Condition Prediction Pavement condition prediction and recommendation for material and construction choices should be included in the report and as part of the digital database.
