Cost: $17 million
Project: In total, the summer project includes resurfacing of 19 percent of Marin’s 421 miles of County-maintained roads and will reduce a backlog of maintenance work estimated to cost more than $160 million. Road rehabilitation will be through asphalt pavement and seal coat resurfacing. Work includes 26 miles of overlay and 47 miles of seal coating. Road maintenance costs increase dramatically when routine maintenance is deferred. Preventive maintenance treatments applied earlier in a pavement life cycle saves on expensive resurfacing treatments later. The County’s Pavement Condition Index, according to the Metropolitan Transportation Authority, stands at 57 on a 1-89 scale and falls under the “at risk” category. Previously Marin scored 48 in 2006 and 49 in 2005. The County expects the index to rise up to 60 with the 2013 Paving Program and has a goal to be in the 70s as soon as possible.
