Description: A geographic representation of the municipal boundaries updated by SanGIS when notified by LAFCO of a recorded annexation or detachment. The revised layer is published as needed once changes are made and verified. Adjustments are also made to this dataset from ongoing landbase maintenance activities.SanGIS will add individual polygons for annexations to a municipal jurisdiction but will not maintain a separate polygon for the agency losing territory. That is, a polygon will be created for the "gain" but the "loss" will be reflected only by modifying the existing boundary. On an annual basis, SanGIS will reconcile the JUR_MUNICIPAL layer with the JUR_MUNICIPAL_ASR layer developed by the Assessor. This will happen when the Assessor publishes the annual TRA updates. SanGIS will accept the Assessor layer as is and use it as the basis for new annexations/detachments going forward. Individual polygons that have been created in the past year will be incorporated into the municipal boundary as shown on the Assessor's TRA updates. NOTE: The County Assessor's Office JUR_MUNICIPAL_ASR layer is the official Municipal Boundary layer; however, it is created for tax purposes and is only updated on an annual basis as required by state law.

Description: ***** BACKGROUND *****In late 1996, the Dept of Conservation (DOC) surveyed state and federal agencies about the county boundary coverage they used. As a result, DOC adopted the 1:24,000 (24K) scale U.S. Bureau of Reclamation (USBR) dataset (USGS source) for their Farmland Mapping and Monitoring Program (FMMP) but with several modifications. Detailed documentation of these changes is provided by FMMP and included in the lineage section of the metadata. A dataset named cnty24k97_1 was made available (approximately 2004) through the California Department of Forestry and Fire Protection - Fire and Resource Assessment Program (CDF - FRAP) and the California Spatial Information Library (CaSIL). In late 2006, the Department of Fish and Game (DFG) reviewed cnty24k97_1. Comparisons were made to a high-quality 100K dataset (co100a/county100k from the former Teale Data Center GIS Solutions Group) and legal boundary descriptions from ( http://www.leginfo.ca.gov ). The cnty24k97_1 dataset was missing Anacapa and Santa Barbara islands. DFG added the missing islands using previously-digitized coastline data (coastn27 of State Lands Commission origin), corrected a few county boundaries, built region topology, added additional attributes, and renamed the dataset to county24k. In 2007, the California Mapping Coordinating Committee (CMCC) requested that the California Department of Forestry and Fire Protection (CAL FIRE) resume stewardship of the statewide county boundaries data. CAL FIRE adopted the changes made by DFG and collected additional suggestions for the county data from DFG, DOC, and local government agencies. CAL FIRE incorporated these suggestions into the latest revision, which has was renamed cnty24k09_1. ***** THIS VERSION*****This version of the county dataset was created as a result of an effort to improve the coastal linework. It uses the previous interior linework from the cnty24k13_1 data, but replaces the coastal linework (including islands and inlets) based on NOAA's ERMA coastal dataset (which used NAIP 2010). In addition to the improved linework, additional coding was added to differentiate inlets and bays, islands, and manmade structures such as piers and breakers. This dataset is one of several available datasets that were created as a group designed to work in topological sync with each other. These "paired" datasets include a basic county dataset (cnty14_1_basic), a basic state dataset (state14_1), an ocean dataset (ocean14_1), a 3 nautical mile CA coastal buffer (cnty14_1_coastbuff), and country/state datasets (both full and neighbor-only - cntrystate14_1_full and cntrystate14_1_neighbor, respectively). Further details about these paired datasets can be found in their respective metadata. This specific datasetrepresents the full detailed county dataset with all coding (islands, inlets, constructed features, etc). The user has the freedom to use this coding to create definition queries, symbolize, or dissolve to create a more generalized dataset as needed.
