Supervisors authorize slurry seal resurfacing contract

Nine roads in greater Fallbrook – and 10 roads if funding permits – will undergo slurry seal resurfacing during 2017.

The San Diego County Board of Supervisors voted 4-0 Dec. 14, with Dianne Jacob recusing herself since her property is along a Jamul road which will benefit from the resurfacing, to authorize the advertisement for bid and subsequent award of a contract to provide slurry seal resurfacing.

The contract is structured to include a base bid consisting of the minimum number of locations and four additive alternatives, or clusters of locations which can be added to the contract if funding permits. Five streets in Fallbrook, two roads in Bonsall, and two streets in Rainbow are included in the base bid which totals 22.92 miles. The four additive alternatives would bring the total to 34.68 miles and result in additional resurfacing to take place in Fallbrook.

The county's Department of Public Works maintains nearly 2,000 miles of road in unincorporated San Diego County, and road crews inspect the roads and prioritize them for preventative maintenance. Visual inspection, mechanical data collection, and resident and community input determine the roads which are most in need of resurfacing.

The road maintenance program also evaluates the preferred rehabilitation strategy. Asphalt concrete pavement overlays are used for severely degraded roads with extensive cracking or potholes, but if the road has only minor cracking and no significant surface damage, a thinner layer of slurry seals may be applied to protect the road. The Department of Public Works expects a contract for asphalt concrete overlay resurfacing to be brought to the Board of Supervisors in early 2017.

The base bid includes the resurfacing of 1.13 miles of Dentro

De Lomas in Bonsall, 0.33 miles in Warmlands Avenue in Bonsall, 0.26 miles of Fifth Street in Rainbow, 0.23 miles of Second Street in Rainbow, and 0.13 miles apiece on the Fallbrook roads of West Alvarado Street, Hawthorne Street, Ivy Street, North Pasadena Avenue, and North Wisconsin Street.

The first additive alternative would resurface 3.20 miles in Borrego Springs, the 4.96 miles in the second additive alternative would provide slurry seal treatment in Valley Center and Julian, and the third additive alternative totals 2.24 miles in Bonita and Spring Valley. Should the contract allow for the fourth additive alternative, 1.36 miles of East Mission Road in Fallbrook would be resurfaced.

Prior year road fund and general fund balances will be used for the estimated $5,719,116 cost of the contract, which includes contingencies and administrative expenses.

All of the work will take place within existing county right-of-way, so no acquisition will be needed. Utility companies have been notified so that trenching work on affected roadway segments can be scheduled before the roads are resurfaced.

The slurry seal resurfacing on a countywide basis is scheduled to begin in spring 2017 and be complete during summer 2017. Traffic control measures will be implemented to limit impacts to community members and other travelers.
