Ventura Countywide Unified Storm Drain Map

The Ventura County Unified Storm Drain System Mapping project is a unified and seamless Countywide Storm Drain GIS. The project, completed in late 2015, consisted of the mapping of natural and engineered drainage system linkages using available topographic information, construction record drawings and other sources. New storm drain data was captured for the Cities of Fillmore, Moorpark, Ojai, Port Hueneme and Santa Paula and was seamlessly combined with the existing storm drain data from the Cities of Camarillo, Oxnard, Simi Valley, Thousand Oaks and Ventura and the County of Ventura Urban Unincorporated Areas.
