Plan Bay Area 2050 Growth Geographies

The Plan Bay Area 2050 Growth Geographies were adopted by the Metropolitan Transportation Commission and Association of Bay Area Governments Executive Board in September 2020. These conceptual areas, which do not supersede local zoning control, are prioritized for new housing and jobs in the Plan Bay Area 2050 Final Blueprint, with specific density and land use assumptions based upon adopted Final Blueprint Strategies. The applicability of different Growth Geographies varies by local jurisdiction based upon the extent to which a jurisdiction has nominated Priority Development Areas, as shown below: All Jurisdictions Priority Development Areas (PDAs): Source - features are from Priority Development Areas (Plan Bay Area 2050). Processing for growth geographies - features from source data were not modified further. Source data is the same as what is in the growth geographies data. Priority Production Areas (PPAs): Source - features are from Priority Production Areas (Plan Bay Area 2050). Processing for growth geographies - features from source data were not modified further. Source data is the same as what is in the growth geographies data. Transit Rich Areas (partial): Source - features are portions of Transit Rich Areas that are within ½ mile of a regional rail station with headways of 15 minutes or better during the AM (6 AM to 10 AM) and PM (3 PM to 7 PM) peak periods, based on posted schedules in January 2020 or service enhancements in Plan Bay Area 2050, including Bay Area Rapid Transit (BART) and Caltrain Baby Bullet station areas. (Note: regional passenger rail systems include Altamont Commuter Express, BART, Caltrain, Sonoma-Marin Area Rail Transit, and Capitol Corridor, but only BART and Caltrain include stops meeting the headway standard.) Processing for growth geographies - these input features were temporary data used to determine the designation, and were clipped to the “exclusion areas” shown below as well as PDAs and PPAs, so were not modified beyond their production. Jurisdictions That Have Nominated Less Than 50 Percent of Their PDA Eligible Areas as PDAs Transit Rich Areas (partial): Source - features are portions of Transit Rich Areas that are not within a PDA, PPA, or within ½ mile of a regional rail station with 15 minute peak headways or less, as identified above. These Transit Rich Areas features include both High Resource Areas and places outside High Resource Areas. The features for this portion of Transit Rich Areas were created by placing a half-mile buffer around passenger rail stations, ferry terminals, and bus stops on routes with peak headways of 15 minutes or less during peak commute period that were selected from Major Transit Stops (2017) data, and by placing a half-mile buffer around passenger rail stations, ferry terminals, and bus rapid transit routes included in Plan Bay Area 2050. Processing for growth geographies - These input features were temporary data used to determine the designation, and were clipped to the “exclusion areas” shown below as well as PDAs and PPAs, so were not modified beyond their production. High Resource Areas: Source - features were created by selecting the intersection of High and Highest Resource Areas from CTCAC/HCD Resource Opportunity Areas (2020) data and a ¼ mile buffer around bus stops with peak headways of 16 to 30 minutes, based upon a January 2020 extract of the Google Transit Feed Specification for all Bay Area transit providers, supplemented by published bus schedules where necessary. Processing for growth geographies - these input features were temporary data used to determine the designation, and are outside the Growth Geographies highlighted above (PDAs, PPAs, and Transit Rich Areas), as well as the “exclusion areas” shown below, so were not modified beyond their production. Exclusion Areas The following areas are excluded from Growth Geographies. Also, these areas were not used in calculating the share of a jurisdiction’s PDA-eligible land locally nominated. County-adopted wildland urban interface areas, where available, Areas of unmitigated sea level rise (i.e., areas at risk from sea level rise through year 2050 that lack mitigation strategies in Plan Bay Area 2050 Environment Element), Areas outside locally-adopted urban growth boundaries, and Parkland and other open spaces within urbanized areas identified in the California Protected Areas Database.
