City digs 12th Street debris basin 

Basin will minimize damage to the road Debris basin

–To protect the city’s investment in the re-surfacing of 12th Street from Spring to Fresno, and to minimize further deterioration of the road surface west of Fresno, the Paso Robles City Council directed staff to install a debris basin as part of the 12th Street Project.

These basins typically require a large area of property and part of the construction cost is to purchase and acquire the property. However, city staff arrived at a solution to minimize cost by using the existing road right-of-way to install the basin. As designed, the basin is part of the roadway and residents can continue to use the road for access.

12th Street is at the downstream end of the Fern Canyon Watershed. This watershed comprises of over four hundred acres located in the county. This watershed is primarily non-urban and has the potential for run-off, leaving the area with debris and silt as it makes it way towards 12th Street. When it rains, silt and debris remain on the street surfaces and gutters.

The Debris Basin located at the west end of 12th Street consists of a “low concrete road” and a “high asphalt road.” Residents will use the “high road” going east and the “low road” going west.

When it rains, the water will flow into the low concrete road and pond. As it ponds, any debris or silt would remain and as the water rises, only “clean” water would leave the Basin and flow into 12th Street. After the storm, City Maintenance crew can easily remove all the silt and debris left behind in the “low concrete road.”

The design of the basin included the installation of a drain inlet at the bottom of the concrete road. When there is only a small amount of water, it will drain into the inlet and percolate below the surface.
