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

October 13, 2020

Storm drain diversion line construction
Redirects water from an existing storm drain into a new storm drain that will eventually connect with the drywells


Drywell drilling
Drilling 100’+ deep to maximize water capture while allowing the water to soak into the ground


Casing installation
Construction method to keep drilled hole open, prevents caving in of surrounding soils for drywell construction


Drywell pipe sections
Drywell sections will be stacked in the drilled holes and will allow water to soak into the soil, eventually recharging the ground water
