Almost a year after publishing our digital case study about the development known as “USC Village” we see the intricate stormwater capture system hard at work after the first rainfall since its opening in August. An article written by Ron Mackovich and published on the USC News website offers understanding of how the many BMPs, including our MaxWell® drywells, are setting the precedent for stormwater capture in Los Angeles.
“The city of Los Angeles requires 85 percent of rainwater to be captured onsite. The USC Village system exceeds that, saving up to 95 percent.” (Mackovich)
In accordance with the City of Los Angeles’s requirements, the team at KPFF Consulting Engineers designed the site’s drainage improvements to a) reduce the impact on existing hydrological conditions and b) minimize, to the maximum extent practical, the impact to the local stormwater conveyance system.
“USC Village’s stormwater collection system functions completely out of sight, gathering up to 98,000 gallons of runoff through 57 area drains on the 15-acre site. The runoff is sent to drywells 6 feet in diameter and up to 60 feet deep.” (Mackovich)
Proposed site improvements included many post-development best management practices (BMPs), which will meet (and we now we can see, exceed) stormwater quantity and quality requirements.
Travis Longcore, assistant professor of architecture, spatial sciences and biological sciences at the USC School of Architecture, reflects on the stormwater system and looks towards restoration of California’s groundwater supply. “Saving stormwater is one step toward retrofitting an urbanized watershed, and it’s a good example of how we should be retrofitting to capture and clean water. Every step like this takes us closer to restoration of our groundwater supply.” (Mackovich).

Groundwater is one of the Nation’s most important natural resources and is the future of water sustainability. If you’re an avid reader of our blog you know that sustainability of water resources is a common theme we tie back into offering low-cost, low-impact solutions. California can stretch their dollar further by awarding funds to cost effective solutions that ensure sustainable water supplies. Ask yourself as a civil engineer or contractor, “what can I do on my projects to impact the sustainability of water supplies in California?” Consider MaxWell drywells for your next project as a low-impact, low-cost solution for deep infiltration and groundwater recharge.
