Description: On March 19, 2019, the Ventura County Board of Supervisors adopted a regional habitat connectivity and wildlife corridor overlay zone and its associated regulations in the Ventura County Non-Coastal Zoning Ordinance (Ord. 4537). The regulations provide protections for wildlife movement that fall within the HCWC when proposed development may degrade those areas. The development regulations that apply within the HCWC focuses on four main objectives: reducing habitat fragmentation; maintaining or improving corridor widths and critical chokepoints where movement is restricted; minimizing physical barriers like roads and fences; and limiting indirect barriers such as artificial lighting, domestic animals, and human disturbances. For more information, please see non-coastal zoning ordinance. The HCWC overlay boundary is based off of the South Coast Missing Linkages: A Wildland Network for the South Coast Ecoregion ( South Coast Wildlands). The report identified critical movement corridors—natural or undeveloped habitat areas that enable wildlife and plants to migrate, forage, breed, and disperse across the landscape. These corridors vary in size and composition, including riparian zones, streams, canyons, and wooded ridgelines, and sometimes extend into vegetated areas within developed regions. Ventura County contains several key linkages identified within the report such as the Sierra Madre – Castaic Connection, the Santa Monica – Sierra Madre Connection (including the Santa Clara River), and the Ventura River Corridor (the Ventura River was added in by the County as a critical wildlife linkage within the HCWC overlay zone). For a detailed explanation of the model, please see South Coast Missing Linkage Project: A linkage design for the Santa Monica – Sierra Madre Connection (South Coast Wildlands, 2006). The locations of the wildlife corridors are shown on the "HCWC Wildlife Corridors" map layer within the County of Ventura Resource Management Agency Ventura County Biological Resources GIS Viewer.https://maps.ventura.org/arcgis/rest/services/SDs/PlanningGIS_Biological/MapServer/7
Description: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.
