Paso Robles is one of few cities in SLO County to implement “Complete Street” concepts
On Friday, March 22nd the Paso Robles City Council and its contractors for the 21st Street Improvement Project will be on hand to celebrate the groundbreaking for that project at 10:00 a.m. at the corner of Riverside and 21st Streets.
The project will improve 21st Street and minimize stormwater impacts locally and downstream. The project is deemed “low-impact” and Paso Robles is one of the few cities in the county to institute such a project.
Design features of the project include:
- Treatment areas for storm water prior to discharging to the Salinas River
- Bioretention areas at several locations
- Use of the median areas to convey storm water flow
- Planting of several trees in special soils to ensure growth and longevity
- Improved pedestrian accessibility
Bioretention is the process in which contaminants and sedimentation are removed from stormwater runoff. Stormwater is collected into the treatment area which consists of a grass buffer strip, sand bed, ponding area, organic layer or mulch layer, planting soil, and plants. Runoff passes first over or through a sand bed, which slows the runoff’s velocity, distributes it evenly along the length of the ponding area, which consists of a surface organic layer and/or groundcover and the underlying planting soil. The ponding area is graded, its center depressed. Water is ponded to a depth of 15 cm (5.9 in) and gradually infiltrates the bioretention area or is evapo-transpired.
The 21st Street Improvement Project is grant-funded via a state (voter-approved) Urban Greening Grant and is estimated to be completed in Spring of 2014. For grant and project questions, contact Ditas Esperanza, Capital Projects Engineer at 237-3861.
