Viewridge Road Stormwater Improvements Project


Water Quality

• Improve local streams and oceans by capturing and treating stormwater and urban runoff by filtering trash, metals, sediment, and other pollutants.

Community Enhancement

• Promote sustainable urban greening through the replacement of paved areas with new trees, drought tolerant landscaping, and drip irrigation.


• Public interest on water resource challenges continues to grow, but awareness of innovative and nature-based solutions is still needed.

The proposed project is located in the unincorporated County community near Viewridge Rd and Topanga Canyon Blvd and serves to improve water quality in Topanga Creek and North Santa Monica Bay while enhancing the community. Features of the project include new drainage infrastructure to capture and treat urban and stormwater flows, a new 850-foot-long raised median with some breaks to allow for ease of access and maintenance, numerous innovative low-impact-development (LID) landscaped parkways, additional trees, drought tolerant plants, drip irrigation, and educational signage.
