  Description:

    Abstract: ACECs differ from other special designations, such as Wilderness Study Areas, in that designation by itself does not automatically prohibit or restrict other uses in the area. While WSAs are managed to a non-impairment standard that excludes surface disturbing activities and permanent structures that would diminish the areas natural character, the management of ACECs is focused on the resource or natural hazard of concern. This varies considerably from area to area, and in some cases may involve surface disturbing actions.

    Purpose: To accurately identfy designated ACEC boundaries.

  Detailed_Description:

    Entity_Type:

      Entity_Type_Label: acec_desig_poly

    Attribute:

      Attribute_Label: OBJECTID

      Attribute_Definition: Internal feature number.

      Attribute_Definition_Source: ESRI

      Attribute_Domain_Values:

        Unrepresentable_Domain: Sequential unique whole numbers that are automatically generated.

    Attribute:

      Attribute_Label: SHAPE

      Attribute_Definition: Feature geometry.

      Attribute_Definition_Source: ESRI

      Attribute_Domain_Values:

        Unrepresentable_Domain: Coordinates defining the features.

    Attribute:

      Attribute_Label: ACEC_ID

      Attribute_Definition: The designed primary key that will uniquely identify a single occurrence of the entity.  The primary key for ACEC will be 10 digits. The first four will be "ACEC" and the last six digits will be a sequential number.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: LOC_ACEC_ID

      Attribute_Definition: The current identifier that was used by a state or field office to identify an ACEC at the state or field office level.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: ACEC_NAME

      Attribute_Definition: The name of the ACEC taken from the Record of Decision and Land Use Plan which officially designated the ACEC.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: CASEFILE_NO

      Attribute_Definition: The number that refers to the serialized case file number of the group of official documents that record the facts, or actions taken, on a specific application, such as an oil and gas lease, exchange, airport lease, easement acquisition, etc. (CMR). This field should be in uppercase (for example, OR035582).  This is a BLM International Organization for Standardization (ISO) assigned number used for identification of all lands and minerals case files including ACECs. This is the link to the LR2000 database. N/A - Not Applicable is the default code and will be used when no casefile number has been assigned. A value of "UNK" indicates unknown.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: LUP_NAME

      Attribute_Definition: The name given to a project that represents the full, official name associated with the project.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: ACEC_EST_ACR

      Attribute_Definition: The measure of the area estimated in the designation process for land use planning.  This is the designated size (acres) and may be different than the actual area.  This does not change.  Acres are calculated using the following formula:  [Acres = Area (in meters)/4046.87].  This may be different than the GIS calculated area of the ACEC polygon.  This field value should be the same for each polygon in an ACEC comprised of multiple polygons.  The values in this field do not change.  Do not use this field to derive GIS acres.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: ROD_DATE

      Attribute_Definition: The date on which the decision is signed by the person who has approval authority for the decisions.    The ROD signing date of the monitoring or activity plan, if any, for the particular ACEC.  The date will be in the format of MM/DD/YYYY.

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: GIS_ACRES

      Attribute_Definition: This is a calculated value of area in units of acres based on the area field created by default within the ESRI Polygon data structure.  For the purposes of a 'national data layer', the data are to be stored in geographic coordinates which do not correspond to ground values.  This requires that there be a standard method for calculating this attribute.   The method used for these data are as follows:  The data are projected into a standard projection such as the ESRI default Albers projection for the continental United States, "US Albers NAD 1983."  Once the data are projected, then a calculation of "SHAPE_Area (square meters) * 0.0002471044  = acres" is applied to the existing 'area' field that is default area created by the ESRI software resulting in the field (Attribute) 'SHAPE_Area'.  Please note that the figure used in this calculation is the factor for converting the US Survey Foot value of for the length of a meter as opposed to the International Standard for converting meters and feet.

    Attribute:

      Attribute_Label: ADMIN_ST

      Attribute_Definition: An administrative unit that identifies the state or geographic area which has administrative jurisdiction over lands, and cases, although the land for a case may not be physically located in a state. Only those states that are BLM administrative states are in the domain for this entity. Example: Montana is the Administrative State for public lands in the geographic States of Montana, South and North Dakota.  A two letter, upper case abbreviation for the administrative state office.  Attribute Domain Assignment:  DOM_ADMIN_ST  Default:  XX

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: ADM_OFC_CD

      Attribute_Definition: BLM administrative office (which is subordinate to the state office) that has jurisdiction and/or management authority over lands within a geographic area.  This is a six-digit code.  In the FBMS Organization Codes, use the six characters after the State designators.  e.g. LLAK030900)

      Attribute_Definition_Source: BLM

    Attribute:

      Attribute_Label: ADM_UNIT_CD

      Attribute_Definition: The BLM administrative unit/office that is a combination of Administrative State Code and Administrative Office Code that fully identifies the geographic area which has jurisdiction over the lands.  This is an eight-character code.  In the FMBS Organization Codes, use the last eight characters (e.g. LLAK030900).  The field should be populated with the office code for the lowest level of the organization with jurisdiction.
