CC2018-03 San Dimas Avenue Et Al Pavement Rehabilitation Project Including the Antonovich Trailhead Parking Lot

 

 

                  Antonovich Trailhead Parking Lot

 

 

San Dimas Avenue Et Al (Highlighted)

 

CC2018-03 San Dimas Avenue Et Al Pavement Rehabilitation Project is a super project that combines pavement rehabilitation of San Dimas Avenue from Via Verde Avenue to Puddingstone Drive, pavement reconstruction of Puente Avenue from Via Verde Avenue to Via Palomares and construction of parking lot improvement on the Antonovich Trailhead (Los Angeles County to reimburse the City for the cost of parking lot improvements).

In total, the project consists of over 530,000 square feet of pavement rehabilitation.  Concrete work includes the installation of over 3,200 linear feet of curb and the installation of 2,200 square feet of sidewalk.  All sidewalk corner ramps (ADA ramps) within the project boundaries will be upgraded to current standards.  Safety enhancements will be added to crosswalks including a solar-powered Rectangular Rapid Flashing Beacon (RRFB) at the Antonovich Trail crosswalk.  Parallel parking stalls and sidewalk will be added to the west side of San Dimas Avenue north of the Trailhead to provide an additional 12 parking spaces for trail users.  Accommodation of the additional parking stalls requires upgrading the existing guardrail and striping modifications.

This project is will start in August 2018 and will take approximately four months to complete.
