BIENNIAL STREET SLURRY SEAL DESCRIPTION: This project would slurry seal approximately 25% biennially or approximately 25 miles and may include cutout and repair of minor pavement failures and installation of striping. The seal typically places a thin layer of sand and oil over city streets. Neighborhood streets should receive a surface treatment (slurry seal) other than an overlay every seven years. Sealing is a preventative maintenance treatment that prevents moisture from penetrating the pavement and softening the base material supporting the pavement. According to studies conducted by the Metropolitan Transportation Commission (MTC), slurry seals have proven to be the best treatment for pavements in good condition based on life cycle cost analysis in that it extends the life of pavement for the least cost. Each application of a slurry seal to streets that are in relatively good condition is expected to extend their useful life by about seven years beyond its current useful life. As a point of general information, the streets that are selected for slurry sealing in any given year are chosen based on a citywide ranking of the condition of all the streets that are maintained by the city. This process is done using the Pavement Management Program (PMP) program developed by MTC. COST SUMMARY: Design and Construction $ 225,000 POTENTIAL FUNDING SOURCES: Capital Projects Fund $ 125,000 Gas Tax Funds $ 100,000 IMPACT ON ANNUAL MAINTENANCE AND OPERATION COSTS: To the extent that this project improves the overall condition of the city’s street system, there will be a lessening of the backlog of street maintenance work. ALTERNATIVES: An alternative is delay the project. This will lead to further deterioration of streets to a point where a slurry seal would be impractical, and a more expensive AC overlay would be necessary.
