,Following adoption of the 2012 Central Valley Flood Protection Plan (2012 CVFPP), DWR funded six regionally-led Regional Flood Management Plans (RFMPs) that describe local and regional flood management priorities and challenges. These RFMPs also identify potential funding mechanisms and site-specific improvement needs.,The Regional Flood Management Planning Regions (RFMP) boundaries were created from the 2013 Levee Flood Protection Zones (LFPZs). Waterways were filled in and the boundaries were broken into the six planning areas by GEI Consultants Inc.,This is the second generation of study areas after the 2012 CVFPP for more specific regional planning efforts with local agencies.,

Developed exclusively for Central Valley Flood Protection Plan (CVFPP) work. Specifically, this area has been delineated in an effort to define the analysis area for environmental analyses of various kinds. Once finalized, a two-mile buffer will be added and form the basis of the potential environmental impacts delineation for CEQA work. Systemwide Planning Area includes lands subject to flooding under the current facilities and operation of the Sacramento-San Joaquin River Flood Management System CWC§ 9611, CWC§ 9641(d, e) (completely contains the State Plan of Flood Control (SPFC) Planning Area). The CVFPP describes facilities and flood management problems in this area and proposes solutions, while not extending the State's responsibility (CWC§ 9603(b)). This feature class represents the Systemwide Planning Area. It is one of the three CVFPP Planning Areas. It is comprised of the following layers:,

Water Plan Planning Areas as part of the detailed Analysis’s Units (DAU) dataset. DAU boundaries match Cal-Fire dataset “cnty24k09_1_poly”.

This dataset is a compilation of ownership rights represented as parcels owned by the Sacramento & San Joaquin Drainage District of the State of California (SSJDD), under the authority of the Central Valley Flood Protection Board (CVFPB).

This line feature class represents levee centerlines for 93 Levee Maintenance Agencies/Reclamation Districts in the Sacramento-San Joaquin Delta. The centerline features contain levee geometry classification that indicates whether a levee segment meets the FEMA’s Hazard Mitigation Plan (HMP) or USACE’s Public Law 84-99 (PL8499) Delta levee standards. There are four categories used in the classification of the centerlines: HMP, Below HMP, Minimally Below HMP, and PL84-99. The classification and other data associated with these centerlines were produced as results of the Levee Geometry Assessment analysis performed by the California Department of Water Resources Delta Levees and Environmental Engineering Branch in 2012. The centerlines used in this analysis are part of the dataset produced from the Delta Levee Anatomy Mapping Project in 2011 through a contract between DWR and the Geographic Information Center at California State University, Chico.

,Department of Water Resources (DWR), Geodetic Branch, Cadastral Surveys reviewed this boundary in July, 2009, and agreed with the linework along with the description below as produced by Joel Dudas in 2002. This boundary was originally produced under the direction of Ray Irving, LS 3278 in August, 1993 (then Chief of the Geodetic Branch) at the request of Margit Aramburu with the Delta Protection Commission. The boundary, at that time, was paper form. The details of how it was prepared are described in the Memorandum dated July 29, 1994, along with additional correspondence between Ray Irving and Margit Aramburu on comments, changes & revisions during the process and are on file at Cadastral Surveys, DWR. (End 2009)***,Delta boundary version 2002.4 Delineates the legal Delta established under the Delta Protection Act (Section 12220 of the Water Code) passed in 1959. This boundary file has been reviewed by a variety of relevant professionals and is considered to be accurate. The exact accuracy is somewhat uncertain, but can be considered acceptable for mapping at 1:24000. The original topographic maps containing the drawn delta border were scanned from the Department of Water Resources. Images were registered to 1:24,000 USGS DRG's in ArcView (ESRI) utilizing imagewarp extension. The Delta boundary was digitized from the registered images. Accuracy within acceptable 7.5 Minute USGS map accuracy standards (1:24000 scale). The original legal boundary maps obtained from the Delta Protection Commission were compiled by DWR Land & Right of Way sometime in the early 1980's. They were based from the legal description in section 12220 of the Water Code, with ambiguities in the Code addressed by the individuals involved in the mapping project at that time. One revision was made to the original maps in the vicinity of Point Pleasant, and is the only difference between this and the 4.2001 version of the legal Delta boundary Arc/INFO coverage.,
