admu_ofc_arc: Line data for Oregon BLM Administrative Units. The Administrative Units (ADMU) data standard contains requirements for administrative boundaries within the Oregon/Washington (OR/WA) Bureau of Land Management (BLM). The OR/WA BLM State Office jurisdiction consists of Districts sub-divided into Field Offices. This dataset was formerly known as Resource Area Boundaries (RAB). The OR/WA BLM administrative jurisdiction encompasses the entire political States of Oregon and Washington. A BLM District or Field Office may cross the political boundary between those States. The dataset includes boundary lines depicting official BLM District boundaries, as approved by the Washington Office, and those depicting administrative BLM Field Office boundaries, as approved by the OR/WA BLM State Director, where the boundary lines are not coincident with the official District line.

The OR/WA BLM State Office jurisdiction consists of Districts sub-divided into Field Offices. This dataset was formerly known as Resource Area Boundaries (RAB). The OR/WA BLM administrative jurisdiction encompasses the entire political States of Oregon and Washington. A BLM District or Field Office may cross the political boundary between those States. The dataset includes boundary lines depicting official BLM District boundaries, as approved by the Washington Office, and those depicting administrative BLM Field Office boundaries, as approved by the OR/WA BLM State Director, where the boundary lines are not coincident with the official District line.

In the SBMP, Fire Management Zones are identified as a subset of BPAs where measurable fuel management treatments are applied. The location and alignment of these zones reflect the risk of bushfires starting and spreading, and impacting on life, property and other assets. The zones established include Asset Protection Zones, Strategic Firefighting Advantage Zones, Land Management Zones and Rural Land Management Zones. The widths and locations of the Zones shown on this map are indicative and the actual widths and location will be determined in consideration of the ACT Fire Management Standards and operational requirements, through the development of Regional Fire Management Plans and Bushfire Operational Plans (including Farm Firewise). Chapter 11 of the SBMP details considerations used in determining the location and extent of Asset Protection Zones adjacent to new and established urban areas. Fire Management Zoning maps will be reviewed as required to reflect significant changes, which may include unplanned bushfires or changes to the location or extent of assets. The Commissioner is responsible for approval of these maps.

The SMA implementation is comprised of one feature dataset, with several polygon feature classes, rather than a single feature class. SurfaceManagementAgency: The Surface Management Agency (SMA) Geographic Information System (GIS) dataset depicts Federal land for the United States and classifies this land by its active Federal surface managing agency. A Federal SMA agency refers to a Federal agency with administrative jurisdiction over the surface of Federal lands. Jurisdiction over the land is defined when the land is either: Withdrawn by some administrative or legislative action, or Acquired or Exchanged by a Federal Agency. The GIS data contained in this dataset represents the polygon features that show the boundaries for Surface Management Agency and the surface extent of each Federal agency's surface administrative jurisdiction. SMA data depicts current withdrawn areas for a particular agency and (when appropriate) includes land that was acquired or exchanged and is located outside of a withdrawal area for that agency. The SMA data do not illustrate land status ownership pattern boundaries or contain land ownership attribute details. This layer is also updated whenever BLM is notified that Lands have been acquired by other Federal Agencies. For additional information regarding an acquisition search the Bureau's LR2000 system: The LND_SurfaceEstate data is edited and maintained in a single polygon feature class. Whenever possible, BLM lands are constructed from the Public Land Survey System (PLSS), also available to the public (PublicLandSurvey.gdb). Alignment of BLM data with the PLSS is a continual process, as the accuracy and density of PLSS data continues to improve and develop. Issues of misalignment with the PLSS are more common with non-BLM management areas. These discrepancies are being addressed at the BLM California State office based on U.S. Department of Interior priorities throughout the State of California
