The new Coastal Biology Building at the University of California in Santa Cruz at the UC Santa Cruz Coastal Science Campus is located right on the northern coastline. The campus houses laboratories, office and teaching facilities for students and marine scientists. The adjoining coastal area is extremely important for marine research. The university directors, site architects and engineers recognized the need to naturally filter auto pollutants from the parking areas to prevent damage to marine life and the fragile ecosystem in the area. UC Santa Cruz vetted several permeable options and decided TRUEGRID PRO PLUS was the right fit for aesthetic, reliability, and cost. The first daily use parking lot and three following high traffic parking lots were built with TRUEGRID PRO PLUS. The clean stone used for infill and base used filters rainwater through the natural bio-remediation process to remove vehicular hydrocarbons, oils and gasoline drippings, nitrogen, phosphorous, etc. as it enters the soils and makes its way to the ocean. One parking lot was designed with added filtration by directing infiltrated, collected water from the TRUEGRID lot into a vegetated swale area…that then then went into the ocean filtered and cleaned.
