California Department of Forestry and Fire Protection (using data from BOR and DOC FMMP) 2004 vector digital data http://gis.ca.gov/casil/boundaries/cnty24k 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 scale Bureau of Reclamation dataset (USGS source) for their Farmland Mapping and Monitoring Program (FMMP) but with several major and minor modifications. Detailed documentation of these changes is provided by FMMP and included as part of the data dictionary. Ideally, state and federal agencies should be using the same framework data for common themes such as county boundaries. This layer provides an initial offering as "best available" at 1:24,000 scale. Additional improvements, including a review of data sources for the coastline, can be added over time based on interagency review and agreement on proposed changes. 1/1/1997 12/31/1997 publication date Complete Unknown -124.510455 -113.497021 42.068685 32.423594 Government, County boundaries, county line, county boundary No Restrictions FRAP disclaimer Read disclaimer within data dictionary supplied when data are downloaded from FRAP site FRAP data librarian CDF - FRAP mailing and physical address

A third area believed to be outdated, but could not be confirmed, was also changed in the Bureau's master file. All three changes are described below. When a county line has changed and no longer agrees with the Bureau's master file, the preferred order for incorporating the new linework into it are as follows: Copying information from digital USGS 7.5' SDTS formatted files. Copying information from digital USGS 100K DLG formatted files. Digitizing off of USGS 7.5' paper quads (if they reflect the new county line). Any other means where a correct boundary can be incorporated. The modified Bureau of Reclamation file contains the following linework changes: Butte-Glenn Counties Background The area in question is the entire Butte-Glenn county line along the Sacramento River. There were subtle and not so subtle differences between the FMMP's existing county line and what the Bureau was calling the county line. Several sources were referenced with no clear indication of where the line fell. In all the maps reviewed there was never a point in the process where the FMMP had to consider multiple interpretations of the county line. It was either FMMP's existing line or the Bureau's. Sources Referenced US Census Tiger File USGS 100K DLG USGS 7.5' DLG USGS 7.5' paper quads USGS 100K mylar quads ETAK State of California Legal text description of Butte County and Glenn County lines. Butte County Planning Department Butte County Public Works Butte County Assessor's Office Butte County Legal Counsel Glenn County Planning Department Glenn County Public Works Glenn County Assessor's Office Result After careful consideration of the sources contacted and/or reviewed, it was determined that the FMMP would adopt the 100K USGS DLG line as the county line between Butte and Glenn County. The biggest obstacles in making this decision were the ignorance of both counties on where their county line fell, and the USGS contradicting itself as to where the line went. The 100K USGS mylar and 100K DLG matched what FMMP was already using, while the 7.5' USGS paper quad and 7.5' USGS DLG identified a different county line. In the end it was decided that FMMP would adopt the 100K DLG since it closely resembled the line the FMMP has used all along for these two counties. The adoption of the 100K DLG line was performed by R. Withers in June 1997. The entire common boundary between Butte and Glenn counties was replaced and is distinguished from the rest of the Bureau's linework by color. The change starts at lat. 39- 23' 02.5349" N long. -121- 53' 20.1887" W and ends at lat. 39- 47' 52.0638" N long. -122- 02' 43.6258" W. Orange-Riverside Counties Background The USGS, Bureau of Reclamation, and the FMMP all had interpreted the county line between Orange and Riverside counties in the same way, but a note from Karen Freeman at the City of Anaheim Planning Department described a minor change that she was aware of between the two. Upon investigation, it was confirmed that a change had occurred. Since the adjustment of the line was written using bearing and distance, R. Withers tried to draw out the line using the precision placement options of Microstation 95 (version 5 mode). The legal text was obtained from the State of California (the county line change is highlighted in bold and is underlined): http://www.leginfo.ca.gov/cgi-bin/calawquery?codesection=gov&codebody=23101 23130.

Sources Referenced USGS 7.5' paper quad City of Anaheim Planning Department US Census Tiger File ETAK State of California legal text description of Orange County. Result The precision placement of the modified Orange-Riverside line was successful. However, the Bureau's line does not take into account minor directional changes north and south of the main area of concern. As a result, the line had to be redigitized from the USGS 7.5' quadrangle Black Star Canyon. The new county line is distinguished from the rest of the Bureau's linework by color. The change starts at lat. 33- 46' 00.4197" N long. -117- 34' 37.4973" W and ends at lat. 33- 52' 39.0641" N long. -117- 40' 42.3113" W. Santa Cruz-Santa Clara Counties Background There had been a long history dating back to the late 1980's(?) regarding the correct placement of the county line between Santa Cruz and Santa Clara counties. The 100K USGS map did not agree with the 7.5' USGS quadrangles and the counties were of little help in resolving placement of the line. At that time the FMMP decided to go with the 100K line. In 1997 the issue came up again because the FMMP line did not match the Bureau's county line. Most of the 7.5' USGS paper quads along the county border were updated by USGS in the early to mid 1990's, and the legal text description of the county line agreed with what was represented on the newer 7.5' quads. Sources referenced State of California Legal text description of Santa Clara County and Santa Cruz County lines USGS 100K DLG USGS 7.5' DLG USGS 7.5' paper quads USGS 100K mylar quads Result The 100K DLG information was incomplete, but matched the 100K USGS paper map where DLG information was available. The 7.5' DLG information though complete, had some quads that matched the newer 7.5' paper maps and some that appeared to match older 7.5' USGS quads. The problem was finally resolved by digitizing the entire Santa Cruz-Santa Clara line off the newer 7.5' paper quads. This process was completed in May 1997 by R. Withers. The change begins in the south where San Benito, Santa Clara, and Santa Cruz counties meet, and ends just past the junction of Santa Cruz, Santa Clara, and San Mateo counties. The new county line is distinguished from the rest of the Bureau's linework by color. The change starts at lat. 36- 53' 57.9613" N long. -121- 34' 49.6766" W and ends at lat. 37- 17' 36.4162" N log. -122- 09' 35.4072" W. Modifications to FMMP County Line's Within Its Files There are two areas where the Bureau's line and the state's legal text description agreed, and the FMMP county line was out of date. A county line adjustment between Kern and Ventura counties resulted in about 9-10 sq. mi. going from Ventura to Kern County. The area was not surveyed on the Ventura side, but falls in the Interim Farmland area of Kern County. The addition was photo interpreted and incorporated into the 1994 Kern County survey area. Ventura County was unaffected since the FMMP does not map that portion of the county. The Tehama-Shasta county line change is located on the Lassen Peak and Gray's Peak USGS quads and involves about 5 sq. mi. going from Tehama to Shasta County. The FMMP loses land from its overall survey area because there's no soil survey information for that portion of Shasta County. All of the land lost is National Forest Service land and was classified as 'X' when it was mapped as part of Tehama County. R.
