The purpose of a stormwater retention system is just that – to retain as much of the rainwater in the native soil as possible while facilitating proper filtration of any excess runoff during storm events.
The retention system allows any excess runoff from the site’s parking lots during rain events to be filtered then directed to the city’s storm drain. At the recently completed project for RBC Transport Dynamics, the city storm drain empties into the Pacific Ocean.
This project has a bio-swale and permeable concrete. Permeable concrete is often referred to as “magic concrete."
What is this system, you ask?
Let’s break it down.
