East Los Angeles Sustainable Median Stormwater Capture Project

East Los Angeles Sustainable Median

Benefits

Water Quality

Infiltration wells and low impact development, such as bioswales, will divert and infiltrate stormwater runoff to help improve the water quality of our rivers, channels, and ocean.

Water Supply

Infiltration wells will divert stormwater runoff into underground aquifers, replenishing our local groundwater supply.

Urban Greening

Planting over 300 trees and drought tolerant landscaping will enhance the community space and reduces the effects of greenhouse gases.

Community and Education

Passive recreation and educational signage will enhance the community space and increase public awareness on sustainable development.


The proposed East Los Angeles Sustainable Median Stormwater Capture Project (Project) located in the unincorporated area of East Los Angeles (East LA), in Landscape Maintenance District Zone 35, will improve water quality, increase water supply and enhance recreation and the community. This Project will capture and infiltrate approximately 21 acre-feet of urban and stormwater runoff from a 3,000-acre tributary area of mostly residential and commercial land areas. The project will also provide above ground improvements such as jogging paths, drought tolerant landscaping, plant over 300 trees, and educational signage.

Updates

Temporary Walking Path Closure

Due to the heavy rain events, the recently completed East Los Angeles Sustainable Median Stormwater Capture Project developed localized settlement along walking paths and landscaped areas. Now that the storm season has officially ended, Los Angeles County Public Works crews will begin repairing the walking paths as soon as April 20th. Repairs to landscaped areas will require more time to complete due to the need for a remediation plan that will minimize impacts to the already well-established landscaped areas and to prevent future settlements from occurring.

Please note the walking paths will not be accessible during the repair work.
