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 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). The parcels include geospatial data and links to related source documents and were created from DWR's cadastral records currently represented as digital GIS, CAD, and scanned documents as well as hardcopy records stored in binders and filing cabinets at DWR headquarters. DWR requires GIS based parcel data to manage land records defining the location of SSJDD land rights and easements for the CVFPB. The GIS representation of land records provides an index to property records, and CAD COGO based mapping will enable the CVFPB and other entities to more efficiently identify property rights. This data set was created to improve the efficiency accessing the land records and the organization of the land records. It is anticipated this data set will serve as the authoritative source for the next 50-100 years when managed with incremental updates reflecting ongoing updates to parcel ownership and rights. Users are advised to read the dataset's metadata thoroughly to understand appropriate use and data limitations. Rights attributes (annotated with "PART OF RIGHTS ATTRIBUTE GROUP: " in the Column Definition within the Entity and Attribute section of this metadata) are restricted to use by the CVFPB and DWR's Geodetic and Real Estate branches. Please see 'Distribution Info' for details. The rest of the attributes may be consumed publicly.

,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.,

,Center lines of the Suisun Marsh levee systems. This dataset is a combination of different Suisun Marsh levee datasets that were edited to be accurate with the current LiDAR available. The use of high-resolution LiDAR, and the products derived from it, allow for levee anatomy to be captured for the surveyed area. This data can further be used for levee maintenance and management, flood modeling and prediction, as well as levee inventories. Since the centerlines are derived from different data sources, some flooded levees are still included and flagged within the dataset.,

State Plan of Flood Control (SPFC) Planning Area is the lands currently receiving protection from the SPFC (CWC§ 9651(g)). State's flood management responsibility is limited to this area.

Boundaries of various types of public agencies with responsibilities that include in part or primarily flood control, system maintenance, and improvement. In California, there are a variety of political entites that are granted self-taxation powers under various California codes in order to perform the basic goal of flood management within an area. This dataset compiles many of the various datasets together to provide the information in one location. It also includes districts that are no longer active political/management entities for archival or historical purposes. The primary type of flood agency in California are known as reclamation districts, and so represent the majority of the records in this database. The quality of the boundary accuracy is highly variable, due to a variety of reasons, including the fact that the original legal boundaries are frequently tied to Swamp Land Survey boundaries that themselves are poorly located by modern mapping standards. This set of boundary delineations represents the latest in a series of nearly 20 significant revisions primarily by DWR Delta Levees Program between 2000-2017 to a dataset first produced by Office of Emergency Services during the 1997 floods. The accuracy and completeness of the data are therefore higher in the Delta than elsewhere. The Division of Flood Management then stored the boundaries in their levee geodatabase that feeds the web mapping application known as FERIX. To produce this final dataset, in 2018 the Division of Engineering Geodetic Branch merged the data used by FERIX, along with other datasets used by the Delta Levees Program, and normalized the attribute table.

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:,

One foot contours developed from Delta LIDAR. LIDAR was developed under a contract between California DWR and URS Corporation (DRMS contract), with Fugro EarthData as lead LIDAR survey contractor. Flights were conducted in 2007 with 9% reflown in 2008. Final products delivered to DWR in 2009. Survey points of accuracy theoretically capable of supporting 1 foot contours. Using processed bare earth point data, Fugro EarthData generated/supplied these contours in raw and smoothed format, and the feature class here are smoothed contours. These data are public domain. Additional information can be obtained from California DWR.
