WESTWOOD—The Westwood Neighborhood Greenway Project started construction measures on December 31, 2019 to improve the Santa Monica Bay water quality conditions. The Greenway Project is located adjacent to the Exposition Light Rail at the Westwood/Rancho Park Station and funded by Proposition O as well as the Santa Monica Bay Restoration Commission.
The project aims to reduce pollutants from urban runoff that flows through the existing underground storm drain under Overland Avenue. The stormwater will be diverted to new bioswales through the use of pump stations for flow through various plant communities, soil mediums, and exposures to sunlight.
Bioswales are linear channels designed to concentrate and convey stormwater runoff while removing debris and pollution. The Westwood Neighborhood Greenway plans to clean and conserve water by late 2020 while providing an island of native habitat for birds and butterflies.
Proposition O authorizes the city of Los Angeles to fund projects up to $500 million that prevent and remove pollutants from regional waterways and ocean. The Westwood Neighborhood Greenway Project along with other approved Proposition O projects seek to make bay waters safer and healthier while meeting Environmental Protection Agency and federal Clean Water Act regulations.
Project components include:
- A diversion structure at the existing storm drain along Overland Avenue
- A sand filter
- Two bioswales
- Two pump stations
- Two hydrodynamic separators
- Native and drought tolerant landscaping
- Interpretive signs
