Stormwater Capture Project

The Merced Avenue Stormwater Capture Project is an investment in sustainability, mobility, and community well-being. This project will create a new bike and walking path connecting Merced Avenue Linear Park to the Rio Hondo Bike Path, providing a safe and scenic route for pedestrians and cyclists.

In addition to improving connectivity, the project will enhance stormwater management by incorporating an underground drainage system and landscaping designed to absorb and filter water naturally. This will help improve local water quality while supporting a greener, healthier environment.

How the Project Works

Today, an open concrete channel runs between Merced Avenue and Brockway Street before draining into the Rio Hondo. The project replaces that channel with an underground culvert and a landscaped bioswale that captures and naturally filters runoff. The space above becomes the linear park, with a bike and walking path that links the Merced Avenue path to the Rio Hondo path.

Project at a Glance

Natural filtration – Captures all dry-weather flow, plus a share of storm runoff, through a bioswale.
Wide reach – Treats runoff from a 670-acre drainage area in El Monte.
Water storage – Holds about 55,000 gallons (0.17 acre-feet).
Cleaner water – Cuts zinc pollution by about 76% and copper by about 73%.
Greener and cooler – Adds native landscaping, more tree canopy, and shade to ease the urban heat-island effect.
Safe connections – Links neighborhoods to safe walking and biking routes.

Community Benefits

This project offers multiple benefits for residents and visitors:

New Bike and Walking Path – A direct connection between Merced Avenue Linear Park and the Rio Hondo Bike Path.
Improved Stormwater Drainage – Reducing standing water and managing stormwater more efficiently.
Native Landscaping & Shade – New trees and plants will enhance the path’s beauty and provide natural cooling.
Safety & Privacy Enhancements – New lighting, fencing, and walls will increase security along the path while maintaining privacy for nearby homes.
