Adventure Park Multi-Benefit Stormwater Capture Project



New infrastructure will divert and treat stormwater runoff to help improve the water quality of our rivers, channels and ocean.


Captured stormwater runoff will be diverted into a nearby sanitary sewer system for further treatment downstream and future reuse.


Installation of Low Impact Development (LID) elements with new trees and drought tolerant landscape will enhance the community space while reducing the effects of greenhouse gasses. Installation on new exercise equipment and new outfields will promote healthy lifestyles.


Educational signage will increase public awareness on sustainable development and the health of the San Gabriel River watershed.

The proposed project is located in the unincorporated County community of South Whittier and serves to improve water quality in the Coyote Creek and the San Gabriel River while enhancing the community. Project will include construction of a new drainage infrastructure to capture and treat stormwater and enhancements to the park, including drought tolerant landscaping with educational signs, new exercise equipment, walking paths and renovated ball fields.
