The 'rehabilitation process currently employed by the City has been geared to benefit both those streets in need of moderate to extensive rehabilitation and those in need of minor reconstruction. The process involves Cold Planing (removing) the top 2" of existing pavement and then installing a 2" AC Overlay. Some of the contributing elements, particularly those involving existing subbase soil conditions and/or content of base material, cannot be mitigated without total reconstruction. Total reconstruction is extremely costly (4 to 5 times that of the City's current Rehabilitation process). Alternatives to total reconstruction are currently being explored for existing streets with an underlying concrete slab construction. 5th St., from "N" St to Congress St, has recently been rehabilitated by using a process involving the addition of a Petromat (a Geotextile fabric grid) layer sandwiched between the original street (after Cold Planing is done) and the final AC Overlay. In addition to those listed in Exhibit A, there are several widely used streets which have some potholes and are beginning to show cracks and wear from the volume of traffic. Among them are: • Mt. Vernon (from the Santa Ana Bridge to Washington St), • Washington St (from 1-215 easterly to the City Limits), • Cooley Drive & Cooley Lane, �► Hunts Lane, • Portions of the Cooley Ranch streets southerly of Washington Ave. These streets do not yet require rehabilitation. With current potholing practices, and the lack of any regularly funded crack seating process, these streets will soon be in the same condition as the streets shown on Exhibit A. An aggressive maintenance program with a permanent patching machine (for potholes) and a rubber crack sealing machine, will appreciably extend the life of these streets. FINANCIAL IMPACT: Exhibit A spread sheet report lists over 2 million dollars worth of streets in the City which need to be rehabilitated. Eligible for Host City Fees funding $ 568,733 Eligible for Gas Tax OR Measure I funding J1.§40 416 Total: $2,109,149 The amount of available funding is to be determined via Reserve Funding Balance and verified by the Finance Department. Note: Copies of REVENUE RECAP REPORT, supplied by the Finance Dept., are attached (Exhibit D) RECOMMENDATION: Staff recommends: 1) The street paving program be reviewed by Council to determine their priority streets from the list provided. If the Council desires to add a street not on the list, it must first be submitted to determine if qualifications for any of the above -noted funding sources can be met and to estimate its potential cost for construction as part of the total project. 2) Approve appropriation of $500,000 from the funding sources identified and authorize staff to select streets from the list provided (Exhibit A), up to the appropriated funding limit.
