Watershed Boundary HUC6

Each drainage area is considered a Hydrologic Unit (HU) and is given a Hydrologic Unit Code (HUC) which serves as the unique identifier for the area. HUC 2s, 6s, 8s, 10s, & 12s, define the drainage Regions, Subregions, Basins, Subbasins, Watersheds and Subwatersheds, respectively, across the United States. Their boundaries are defined by hydrologic and topographic criteria that delineate an area of land upstream from a specific point on a river and are determined solely upon science based hydrologic principles, not favoring any administrative boundaries, special projects, or a particular program or agency. The Watershed Boundary Dataset is delineated and georeferenced to the USGS 1:24,000 scale topographic basemap. Hydrologic Units are delineated to nest in a multi-level, hierarchical drainage system with corresponding HUCs, so that as you move from small scale to large scale the HUC digits increase in increments of two. For example, the very largest HUCs have 2 digits, and thus are referred to as HUC 2s, and the very smallest HUCs have 12 digits, and thus are referred to as HUC 12s.

FWS Water Infrastructure - Public View

***THIS ITEM IS PUBLIC AND READ ONLY*** The Water Resources Inventory feature layer is a spatial inventory of miscellaneous point and line water related features on U.S. Fish and Wildlife Service lands. Management Actions and Maintenance related tables are included. This is a national authoritative data layer constructed by the NWRS Geospatial Advisory Committee assets sub-team based on the success of the Region 3 NWRS Water Resources Inventory dataset. This is a read-only, public AGOL View of [FWS_Asset_Water_Resources_Inventory]. Content can be added/edited by joining the [FWS Asset Editing Group] if a member of the FWS Organization. This public view only shows records that meet the following criteria: * Record Status = "Valid" * Public Viewable = "Yes" Data Set Contact: U.S. Fish and Wildlife Service Natural Resource Program Center, GIS Team Lead, [richard_easterbrook@fws.gov] U.S. Fish and Wildlife Service Catalog (ServCat) Record - [https://ecos.fws.gov/ServCat/Reference/Profile/154161] For more information on the data that can be collected, see [NWRS GAC FWS Assets sharepoint].
Administrative Assembly Districts

The Assembly District boundaries are the result of the Alaska State Redistricting and the Borough Reapportionment process. Beginning with the Decennial Census, the population is divided as equally as possible within each district. Both processes involve moving district lines so that each district has an equal (or close to) number of people for fair 'one-person, one-vote' representation, and to resolve malapportionment. The state moves lines for State House & Senate boundaries, and the Borough changes Assembly District boundaries. Boundaries of the seven assembly district boundaries of the Mat-Su Borough. Following the 2020 US Census, and the resulting SOA 2022 May Interim Proclamation Plan, new voting precincts were created by SOA DOE which then initiated the reapportionment of MSB assembly districts. The new districts were developed to eliminate split precincts. These boundaries were adopted and put into effect in July 2022.
Administrative Core Area Planning

Overview This feature service represents the Administrative Core Area Planning boundary as defined in the Matanuska-Susitna Borough Code, chapter 17.61, which defines the Core Area. The Core Area is characterized by its numerous political, administrative, and advisory bodies that collectively share responsibility for making and implementing local governmental decisions within this region. Feature Layer * Administrative Core Area Planning: This layer delineates the geographical extent of the Core Area within the Matanuska-Susitna Borough. It contains spatial measurements such as area and perimeter in various units, as well as attributes related to elevation and thickness, which may be relevant for planning and geographic analysis. The data supports governance and administrative planning by providing a clear spatial context of the Core Area. Geographic Coverage The data covers a focused region within the Matanuska-Susitna Borough in Alaska, providing important spatial information pertinent to local government planning efforts. Use Cases * Supporting local government decision-making and administrative planning within the Core Area. * Providing planners and policymakers with spatial data for comprehensive land use and community development. * Serving as a reference for creating maps and analyzing governance boundaries in the Borough.

SOA DCCED DCRA Research and Analysis is not the authoritative source for this data. For more information and for questions about this data, see: [Tribal Leaders Directory].
Administrative Fire Service Areas

This dataset represents the official Fire Service Areas within the Matanuska-Susitna Borough as established in the Borough Code of Ordinances. Fire Service Areas delineate geographic regions where organized fire protection services are provided. Properties located within these areas are assessed an additional mill rate to fund fire response, prevention, and related emergency services. The boundaries are intended for planning, assessment, and informational purposes and reflect legislatively adopted service areas. This layer may be used to support public safety analysis, tax assessment review, land use planning, and map visualization related to fire protection services within the Borough. Display of fire service area boundaries; mapping, parcel attribute QC, online display, public distribution
Administrative City Boundaries

This feature class was developed to display incorporated city boundaries within the Matanuska-Susitna Borough for mapping, online visualization, and general distribution. The dataset represents the official corporate limits of the three cities located within the Borough: Houston, Palmer, and Wasilla. The city boundary polygons are intended for general reference and cartographic use and support applications such as mapping, planning, analysis, and public information. This layer provides a consistent geographic representation of municipal boundaries within the Mat-Su Borough..
Administrative Metropolitan Planning Area

After the 2020 Census, the core area of the Mat-Su Borough was designated an “Urbanized Area” thus triggering the need to establish a Metropolitan Planning Area (MPA) to be governed by a newly established Metropolitan Planning Organization (MPO). The Metropolitan Planning Organization (MPO) is a transportation decision-making and planning body with representatives of local, state & federal government and transportation authorities. It is mandated by the federal government for urban areas with a population greater than 50,000. The MPA boundary encompasses the new Urbanized Area and the contiguous area that is expected to become urbanized within a 20-year forecast period.
