Description: The Green Region Resource Areas (GRRAs) dataset consists of information on natural hazards, sensitivities, farmland, tribal nations, military installations, and natural assets. The GRRA datasets are developed to support coordinating regional land use with transportation strategies and address the region’s growth and sustainability challenges to protect the region’s natural assets and reduce future risks from climate change. GRRAs are organized into three Data Categories with seven Topic Areas: Climate Hazards (flood hazard, sea level rise, wildfire risk), Habitat (habitat value, wildlife corridors, aquatic resources), and Agriculture (farmland). Agriculture is a vital GRRA category, valued not only for its economic importance but also for its contribution to regional sustainability, food security, and resilience. Preserving agricultural lands helps limit urban sprawl, protect carbon sequestration capacity, and sustain the long-term viability of California’s farming economy. Two data sources inform the farmland Topic Area within the data category of Agriculture: Farmland and Monitoring Program (FMMP), 2022, California Department of ConservationCalifornia Williamson Act Enrollment, 2024, California Department of ConservationData sources are merged by Topic Area, and this dataset counts the number of overlapping Topic Areas for impacted locales in the region (Farmland, Williamson Act parcels). Scores range from 0 to 1. This dataset is accompanied by similar versions for Climate Hazards and Habitat, as well as an overall summary of overlaps amongst the topic areas within the three datasets. The following datasets are a subset of the Green Region Resource Areas (GRRAs). The GRRAs dataset consists of information on natural hazards, sensitivities, farmland, tribal nations, military installations, and natural assets. The GRRA datasets are developed to support coordinating regional land use with transportation strategies and address the region’s growth and sustainability challenges to protect the region’s natural assets and reduce future risks from climate change. The following datasets are included within Agriculture:Farmland - The Farmland Mapping and Monitoring Program (FMMP) (2022) provides a statewide inventory of agricultural land, mapping farmland and grazing land at a minimum unit of 10 acres. For the purposes of mapping GRRAs, only prime farmland, farmland of statewide importance, farmland of local importance, unique farmland, and grazing land were factors carried through to the dataset.Williamson Act parcels - The California Williamson Act Enrollment (2024), which identifies lands under Williamson Act and Farmland Security Zone contracts, though it does not necessarily provide information as to the location of Agricultural Preserves within each county.Data Sources: Southern California Association of Governments (SCAG); California Williamson Act Enrollment, 2024, California Department of Conservation; Farmland Mapping and Monitoring Program (FMMP), 2022, California Department of Conservation.
