This geodatabase includes the boundaries of the California Natural Resource Agency's State Conservancies. The collection of the State Conservancies boundaries was initiated in January 2012 by the Sierra Nevada Conservancy, and the geodatabase was updated in March 2015 to include the California Coastal Conservancy boundary. The geodatabase was constructed from GIS data requested from each of the State Conservancies. The following documentation describes the contacts who provided data, and where available, the type of spatial information provided.
Baldwin Hills Conservancy:
A shapefile of the Baldwin Hills Conservancy boundary was requested and received from Amanda Recinos, amanda@greeninfo.org, of GreenInfo Network on behalf of the Executive Officer of the Baldwin Hills Conservancy, David McNeill, on 10 January 2012. This boundary has not been modified from the original boundary provided.
California State Coastal Conservancy:
The California State Coastal Conservancy was updated by San Jenniches, sjenniches@scc.ca.gov, of the Coastal Conservancy in Fiscal Year 2014-2015. The SNC did not receive the boundary directly from the Coastal Conservancy; the feature class was provided by Nickolas Perez, Nickolas.Perez@water.ca.gov, of the California Natural Resources Agency to the SNC on 30 April 2015.
Coachella Valley Mountains Conservancy:
A shapefile of the Coachella Valley Mountains Conservancy boundary was requested and received fromKerrie Godrey, kgodfrey@cvmc.ca.gov, of the Coachella Valley Mountains Conservancy on 10 January 2012. This boundary has not been modified from the original boundary provided.
Delta Conservancy:
A shapefile of the legal Delta and Suisun Marsh boundaries were provided by Elisa Sabatina with the Delta Conservancy, Elisa.Sabatini@deltaconservancy.ca.gov, on 10 January 2012. This boundary has not been modified from the original boundary provided.
Rivers and Mountains Conservancy (San Gabriel/Lower LA):
A shapefile of the Rivers and Mountains Conservancy was provided by Luz Torres, ltorres@rmc.ca.gov, of the Rivers and Mountains Conservancy on 10 January 2012. This boundary has not been modified from the original boundary provided.
San Diego River Conservancy:
Michael Nelson, mnelson@sdrc.ca.gov, the Executive Officer of the San Diego River Conservancy reported via email on 11 January 2012 that no prior GIS boundary existed for the Conservancy. Mr. Nelson provided written consent to the SNC, via an email dated 11 January 2012, to develop the San Diego River Conservancy GIS boundary from a PDF document supplied by Mr. Nelson that showed the general location of the San Diego River Conservancy’s boundary as occupying a one half mile buffer from the San Diego River. This boundary has not been modified from the original boundary provided.
San Joaquin River Conservancy: The San Joaquin River Conservancy boundary was created from using both the legislation description of the boundary and a pdf version of the San Joaquin River Conservancy boundary provided by Marile Colindres, marile.colindres@sjrc.ca.gov, of the San Joaquin Conservancy on 24 February 2012. This boundary has not been modified from the since the creation of the boundary from the legal description in 2012.
Santa Monica Mountains Conservancy:
The SNC was not able to acquire GIS data from the Santa Monica Mountains Conservancy staff; therefore, the SNC created a boundary to represent the Santa Moninca Mountains Conservancy by using the description of the Conservancy from their website. Specifically, the SNC used the text from their website to select watersheds for GIS boundary: “the Santa Monica Mountains Conservancy zone covers an area from the edge of the Mojave Desert to the Pacific Ocean. The zone encompasses the whole of the Santa Monica Mountains, the Simi Hills, the Verdugo Mountains and significant portions of the Santa Susana and San Gabriel Mountains. In addition, the Mountains Recreation and Conservation Authority also owns or manages thousands of acres in the Sierra Pelona Mountains and in the Whittier-Puente Hills. From north to south, these areas drain into the Santa Clara River, Calleguas Creek, numerous smaller coastal watersheds in the Santa Monica Mountains, and the Los Angeles River and Rio Hondo.” This boundary was created using this text description in February 2012; the boundary has not been updated since the SNC’s creation of this boundary.
Sierra Nevada Conservancy:
The SNC’s boundary was mapped to correspond with statute AB 2600 (2004) and as re-defined in AB 1201 (2005). Work on the boundary was completed by CalFire, GreenInfo Network, and the California Department of Fish and Wildlife (Will Patterson). The meets and bounds description of the area as defined in statute: PRC Section 33302 (f) defines the Sierra Nevada Region as the area lying within the Counties of Alpine, Amador, Butte, Calaveras, El Dorado, Fresno, Inyo, Kern, Lassen, Madera, Mariposa, Modoc, Mono, Nevada, Placer, Plumas, Shasta, Sierra, Tehama, Tulare, Tuolumne, and Yuba, described as the area bounded as follows: On the east by the eastern boundary of the State of California; the crest of the White/Inyo ranges; and State Routes 395 and 14 south of Olancha; on the south by State Route 58, Tehachapi Creek, and Caliente Creek; on the west by the line of 1,250 feet above sea level from Caliente Creek to the Kern/Tulare County line; the lower level of the western slope's blue oak woodland, from the Kern/Tulare County line to the Sacramento River near the mouth of Seven-Mile Creek north of Red Bluff; the Sacramento River from Seven-Mile Creek north to Cow Creek below Redding; Cow Creek, Little Cow Creek, Dry Creek, and the Shasta National Forest portion of Bear Mountain Road, between the Sacramento River and Lake Shasta; the Pit River Arm of Shasta Lake; the northerly boundary of the Pit River watershed; the southerly and easterly boundaries of Siskiyou County; and within Modoc County, the easterly boundary of the Klamath River watershed; and on the north by the northern boundary of the State of California; excluding both of the following: (1) The Lake Tahoe Region, as described in Section 66905.5 of the Government Code, where it is defined as "Region." (2) The San Joaquin River Parkway, as described in Section 32510. According to GreenInfo Network and the California Department of Fish and Game, the blue oak woodland used to define a portion of the Sierra Nevada Conservancy's western boundary was delineated using referenced vegetation and imagery data.
Tahoe Conservancy:
The Tahoe Conservancy boundary was created by using the Tahoe Regional Planning Agency (TRPA) boundary received from the Tahoe Conservancy staff and clipping the TRPA boundary to the State of California boundary, using the Teale Albers projection. The TRPA boundary was received by the SNC from the Tahoe Conservancy staff in 2011, and the Tahoe Conservancy boundary was created by the SNC in 2012.
Notes:
Some conservancy boundaries overlap.
This layer represents current city boundaries within Los Angeles County. The Los Angeles County Department of Public Works provides the most current shapefiles representing city boundariesand city annexationson the Los Angeles County GIS Data Portal. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California. Numerous records are freely available at the Land Records Informaitonwebsite, hosted by the Department of Public Works.
Principal attributes include:
CITY_NAME: represents the city's name.
CITY_TYPE: may be used for definition queries; "Unincorporated" or "City".
FEAT_TYPE: identifies the feature that each polygon represents:
Land - This value is used for polygons representing the land masses, if you want to see only land features on your map.
Pier - This value is used for polygons representing piers along the coastline. One example is the Santa Monica Pier.
Breakwater - This value is used for polygons representing man-made barriers that protect the harbors.
Water - This value is used for polygons representing navigable waters inside the harbors and marinas.
3NM Buffer - This value is used for polygons representing the three seaward nautical miles within the cities' limits, per the Submerged Lands Act.
POPULATION: Information in this field is supplied by Mark Greninger (mgreninger@cio.lacounty.gov).
