Soil Survey Maps

What are soil survey maps?

They are maps where the boundaries of soil types are overlaid onto aerial photos to identify the locations of different types of soil.

For online soils maps, see the USDA Natural Resources Conservation Service online Web Soil Survey at http://websoilsurvey.nrcs.usda.gov/app/

Soil survey maps and data for Western Riverside and Orange Counties can be obtained by bringing a property location map to the RCRCD office. Soil maps for properties within the Riverside-Corona Resource Conservation District are published in the Soil Survey, Western Riverside, California (published in 1971), which is also available at local libraries. US Forest Service Lands are not included. Copies of individual soils maps are provided free of charge.

Soil maps can be used for site analysis, water management evaluation, erosion control planning, and Environmental Impact Reports. Soil surveys provide information about a soil's suitability for crops, building sites, roads, septic systems, and land use.

Soil surveys include information about a soil type’s infiltration rate, depth to bedrock or parent material, slope, load bearing capacity, shrink-swell capacity, and more. Included in the survey are the Unified and AASHO engineering classifications for each type of soil that is mapped.

If you would like soils information, please contact District Conservationist Bob Hewitt with your property location (township, range, section, etc.) at (951) 654-7733, or Robert.Hewitt@ca.usda.gov

To obtain aerial photos, contact the Riverside County Flood Control office or a private company, such as Rupp Aerial Photography in Corona. Find photos by visiting an online source, such as mapquest.com or google maps.
