The City of San Angelo could begin its annual program of street maintenance as early as this Friday, Aug. 21. The sealcoating of designated streets throughout the city represents the first year of an eight-year cycle to maintain every City roadway in San Angelo.

The project’s start date is contingent upon the contractor’s availability. Weather permitting, the work is anticipated to be completed within three weeks. Motorists are asked to avoid parking on affected streets until after construction is complete. For maps highlighting the streets that will be sealcoated in six areas across San Angelo, visit cosatx.us/engineering.

Sealcoating is a preventative measure that involves applying a thin layer of asphalt and rock to a street’s surface to prevent moisture from seeping into the asphalt and damaging the roadway’s base. The process extends the life of a street’s surface.

The City Council awarded a $3.2 million contract to Ronald R. Wagner & Co. of Kendalia, Texas, to perform the sealcoating. That represents a more than five-fold increase over the $600,000 the City spent on sealcoating in 2012.

The contractor will also prime coat and sealcoat the parking lots at the City-owned San Angelo Soccer Association complex on Glenna Street. A prime coat is a thin layer of asphalt or emulsion sprayed on base material that gives sealcoat a surface to which it can adhere.

The streets involved in the maintenance program were determined following an analysis and prioritization of street conditions by the City’s Engineering Services and Street & Bridge divisions. A contracted analysis that involved the use of high-tech equipment to determine the condition of every City-maintained street in San Angelo will be presented to the City Council in the coming weeks. That analysis will serve as a guide to determine the best approach to maintaining or to reconstructing each roadway.
