SAN DIEGO — The condition of surface streets in San Diego has gotten significantly better over the past five years, but there’s still room for improvement, according to a long-awaited assessment released Tuesday.

The survey conducted by Cartegraph Systems Inc. is a follow-up to a 2011 report that found that San Diego’s 2,800 miles of paved streets and 200-plus miles of paved alleys earned an overall rating of 59 out of 100. The new rating is 72.

A street in good condition has a rating of at least 70. A figure between 40 and 69 means a street is in fair condition. Below 40 is poor.

The assessment team examined 97 percent of the city’s road network to assess the condition of pavement and the smoothness or roughness of the ride.

According to the report, 60 percent of the network is in good condition, 34 percent is fair and 6 percent is in the poor category. That compares to the 2011 assessment, in which only 34 percent of the roads and alleys were in good condition, 44 percent were fair and 22 percent poor.

Since the assessment five years ago, 520 miles of surface streets have been repaved, 11 miles of concrete roads have been replaced and slurry seal has been applied to 856 miles, according to the city. Slurry seal is a coating designed to maintain roadways in good or fair condition.

The updated assessment, which officials will use to prioritize repaving projects, is scheduled to be presented Thursday to the City Council’s Infrastructure Committee.
