12th STREET GREEN STREET UPGRADE
The City of Paso Robles is pursuing a Proposition 84 Grant to fund an upgrade of five continuous blocks of 12th Street, between Fresno Street and Spring Street to a "complete/green" street that meets several objectives, including:
Reduce the volume and intensity of stormwater runoff;
Increase groundwater recharge;
Improve pedestrian and bicyclist mobility and safety, thus improve community health and reduce air pollution;
Shade the street with trees; and
Promote infill and redevelopment.
12th Street will be upgraded to park-like street with traffic calming features, bicycle lanes, natural drainage features, multiple shade trees, and storyboards explaining the design for the public. The project also includes upgrading an underground waterline in 12th Street from a 6 inch line to an 8 inch line.
12th Street has a mix of existing uses located along it, including commercial and residential. 12th Street transitions from lower density single family development to multi-family residences to more intensive commercial uses from Fresno Street at the west end of the project site toward Spring Street at the downtown commercial core. The street was established decades ago in the natural drainage course of Fern Canyon Creek. 12th Street functions as a tributary for approximately 500 acres of upland land. Currently, stormwater cannot infiltrate due to paving and storm drains that convey stormwater directly to the Salinas River. Large storms flood the street, cause erosion, and create traffic hazards. The project area is entirely within a disturbed urbanized area.
