Marin Gateway Flood Control

CLIENT: Marin Gateway GARP, LLC
SERVICES: Infrastructure Asset Management


There is a pond located near the Marin Gateway Shopping Center that had a poor drainage system, causing the highway to flood during large rain storms. Pipe & Plant was tasked with inspecting the drainage system infrastructure to identify structural deficiencies that may be causing the problem.


We identified that the primary cause of the flooding was due to a section of pipe missing in the storm drainage system, resulting in the reduction of the system’s overall flow capacity. We set up flood prevention measures, which included pumps and muscle wall to prevent flooding of the highway during large rain storms. Our solutions reduced the amount flooding at the Marin Gateway Shopping Center by restoring their drainage system to full capacity.
