Award Winning Training Facility


In 2012, shortly after purchasing the property, the company saw an opportunity to improve the site’s condition by constructing an array of functional and attractive water quality BMPs.

Over the next few years, CASC team members worked together to plan, design and build a demonstration site that would reduce stormwater discharges, provide a pleasant work environment, and educate those interested in integrating similar BMPs on sites elsewhere.

Trainees and others are welcome to tour the Grounds at our Corporate Headquarters in Colton, CA.
