Description: California's Coastal Zone generally extends seaward to the state's outer limit of jurisdiction, including all offshore islands, and inland to approximately 1,000 yards from the mean high tide line (MHTL) of the sea, or in significant coastal estuarine, habitat, and recreational areas to the first major ridgeline paralleling the sea or five miles from the mean high tide line of the sea, whichever is less. In developed urban areas the zone generally extends inland less than 1,000 yards.Public Resources Code (PRC) Section 30103(a) specifically defines California's Coastal Zone as that land and water area of the State of California from the Oregon border to the border of the Republic of Mexico depicted on maps identified and set forth in Section 17 of that chapter of the Statutes of the 1975-76 Regular Session enacting PRC Division 20 (the Coastal Act of 1976). PRC Section 30103(b) directed the Coastal Commission to prepare and adopt more detailed 1:24,000 scale Coastal Zone Boundary (CZB) maps, which occurred March 1, 1977. These 161 adopted maps provide the official basis for all other representations of the landward CZB, including this one. The digital version of the CZB created by developing this shapefile is a conformed copy of the official boundary, and in some locations reflects legislative changes and Coastal Commission minor adjustments adopted from time to time since March 1977.

Description: The Mendocino County Street Centerline file consists of polylines representing the approximate centerline for the roads included in the file. Centerline data for Federal and State Highways as well as City and County maintainted roads were obtained by the use of Global Positioning System, (GPS) equipment and software. All street centerlins included in the file with the exception of private roads were mapped using a Trimble ProXR reciever, utilizing an external dome antenna mounted to the roof of a motor vehical. As the roads were driven, GPS data was collected at one second intervals. An offset option was utilized to obtain the approximate road centerline. Trimble Pathfinder software was used to post process the data using additional GPS base station data. Data for private road centerlines were developed from the U.S. Geological Survey Digital Line Graph road centerline file, this data was then modified using available aerial imagery as a control. Aerial imagery included U.S.D.A. NAIP imagery as well as selected local high resolution black and white aerial imagery. All road name data was obtained from the agencies that maintain or have ownership responsiblities for the road in question. Road names for private roads were obtained from the agency that has jurisdiction to name the road as per resoution or ordinance.

Description: This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). The National Wetlands Inventory - Version 2, Surface Waters and Wetlands Inventory was derived by retaining the wetland and deepwater polygons that compose the NWI digital wetlands spatial data layer and reintroducing any linear wetland or surface water features that were orphaned from the original NWI hard copy maps by converting them to narrow polygonal features. Additionally, the data are supplemented with hydrography data, buffered to become polygonal features, as a secondary source for any single-line stream features not mapped by the NWI and to complete segmented connections. Wetland mapping conducted in WA, OR, CA, NV and ID after 2012 and most other projects mapped after 2015 were mapped to include all surface water features and are not derived data. The linear hydrography dataset used to derive Version 2 was the U.S. Geological Survey's National Hydrography Dataset (NHD). Specific information on the NHD version used to derive Version 2 and where Version 2 was mapped can be found in the 'comments' field of the Wetlands_Project_Metadata feature class. Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. This dataset should be used in conjunction with the Wetlands_Project_Metadata layer, which contains project specific wetlands mapping procedures and information on dates, scales and emulsion of imagery used to map the wetlands within specific project boundaries.

Description: This dataset (SRA16_1) represents our initial determination of SRA status as of 7/1/16 and will be used to generate the preliminary list of SRA parcels that may be eligible for the SRA Fees bills to be mailed in 2017. The initial determination of SRA status as of 7/1/16 will be compared to 7/1/16 county assessor roll files to determine if any SRA parcels are actually federally owned or part of an incorporated city. The result will be released as our final determination of SRA status as of 7/1/16, SRA16_2.

Description: The Mendocino County Assessor Parcel file consists of Assessor parcel polygons with attribute data derived from the County's property system database. Multiple County Departments contribute data to the property system. The original parcel boundary data was derived from scanned and georeferenced Assessor map pages that were then digitized using "heads-up" digitizing methods, USDA NAIP imagery as well as selected local high resolution black and white aerial imagery were used as control data. Subsequent updates utilize COGO methods when survey data is available. Assessor parcels do not necessarily constitute legal land parcels.
