Geographic Information Systems

The Riverside County Flood Control and Water Conservation District has been developing its Geographical Information System for over thirty years. The GIS team provides a variety of services including creation and data editing, research, analysis, application development, mobile solutions and map production. We develop data and applications to provide helpful geographic information for internal, external and countywide agencies. We have many data layers completed including our District facilities, flood zones, encroachment permits and many others. We currently utilize Oracle Spatial, SQL Server, and ESRI products.

GIS @ the District

GIS is a computer-based technology that combines geographic features with attribute data to visualize, explore, query, edit, and analyze geographical information. The most valuable aspect is being able to analyze information spatially while serving as a decision-support tool for analysis of real-life decisions regarding emergency disaster areas, floodplains, water quality, and environmental. GIS provides the ability to create full-color custom maps and graphics based on a collection of data along with aerial photography. Databases and maps are part of the GIS technology and provide the base from which vast amounts of information can be stored, maintained, and analyzed with endless capabilities. The GIS section is an integral part of the Watershed Analytics Division and District.

**Note: In some cases dual soil designations such as “B/D” has been assigned to an area. This indicates the infiltration characteristics are too variable, either geographically or with time, to assign the soil to a single classification. In such cases the more conservative value is recommended for design hydrology. Please reference the District's Hydrology Manual, Section C for further information.
