Short Description of Work:
The 25th Avenue Sanitary Sewer Relief Line Project (Project) site is located along 25th Avenue between Flores Street and South Delaware Street in the City of San Mateo. The project includes the construction of a new sanitary sewer relief pipeline ranging in size from 21 inches to 30 inches.
The Project’s primary objective is providing future relief capacity to the existing 18-inch sanitary sewer in El Camino Real during wet weather events as well as capacity for accommodating planned upstream pipeline improvement projects to minimize the potential of sanitary sewer overflows.
The proposed sewer alignment would cross under El Camino Real and Caltrain tracks at 25th Avenue and tie into the future downstream sanitary sewer improvements at South Delaware Street.
Benefits of Work:
Reduce potential sanitary sewer overflows in the City
Short term traffic, street parking, and pedestrian impacts during construction
The City is soliciting sealed proposals from construction contractors at this point. The adopted Initial Study/Negative Declaration is available for the public to review at the Department of Public Works.
