This geologic map and preliminary cross sections of central and east Anchorage, Alaska, are based on previous mapping, limited new photointerpretation, and available subsurface data. Using PC-based Geographic Information System (GIS) software, the existing geologic map has been updated and simplified by adding recent fill deposits and combining units of similar genesis, composition, and age that are also recognizable in the subsurface. The GIS database consists of a USGS geologic map and over 4,000 geotechnical boreholes and water-well logs provided by numerous public and private sources. Geologic cross sections were developed by using GIS to project graphic lithologic logs into scaled vertical layouts along selected lines. Stratigraphic units were manually correlated using the log sections as guides. Identification and correlation of subsurface units are somewhat hampered by complex glacial geology, sparseness of deep boreholes, and significant variation in lithologic descriptions among many drillers. Although these limitations result in some generalized, undifferentiated geologic units, the differences among interpreted units are of the level desired by the geotechnical user community for highlighting engineering and seismic behavior.

This map contains property related information by parcel, lease, economic unit. A parcel of land is generally identified by lot and block from a recorded subdivision plat.Leases are agreements related to the ownership or management of a parcel or groups of parcels.An ‘economic unit’ is comprised of 2 or more parcels of property which are combined into 1 unit; essentially this is done for tax assessment purposes.Example: Hillstrand Subdivision was recorded in 1946 and included approximately 25 lots; the physical building for this business is on 7 of these lots. Rather than assessing the owners a portion of the property value and somehow dividing this number by 7 for a valuation on each lot the Municipality created 1 economic unit for this business by combining these 7 lots into 1 for tax assessment purposes.

This map is one of a series of four 1:25,000-scale quadrangle maps (Anchorage C-7 NW Quadrangle) intended to provide information on the geology and construction materials along the southern margin of the Talkeetna Mountains between Little Susitna River and Nancy Lake, Alaska. Additionally, the geologic map portrays faults, if present, as well as other lineaments that represent either faults or erosional features.

These data were automated to provide an accurate high-resolution historical shoreline of Kink Arm - Anchorage, Alaska suitable as a geographic information system (GIS) data layer. These data are derived from shoreline maps that were produced by the NOAA National Ocean Service including its predecessor agencies which were based on an office interpretation of imagery and/or field survey. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.

MOA Survey Benchmarks

The Circumpolar Arctic Vegetation Map (CAVM) is a geoecological map of the entire Arctic with a unified legend. It is the first vegetation map of an entire global biome at a comparable resolution. It was funded by the US National Science Foundation (OPP-9908-829), the US Fish & Wildlife Service, the US Geological Survey and the US Bureau of Land Management. The CAVM region is north of the climatic limit of trees and is characterized by an arctic climate, arctic flora, and tundra vegetation. It excludes tundra regions than have a boreal flora such as the boreal oceanic areas of Iceland and the Aleutian Islands and alpine tundra south of the latitudinal treeline. The map was published at 1:7.5 million scale and displays the vegetation using 15 units (CAVM Team 2003, legend details: www.arcticatlas.org/maps/themes/cp/cpvg). The methods used to make the map are described in Walker et al. 2005. The CAVM is a polygon (vector) map. The GIS data are in shapefile format, and include fields for bioclimate subzone, floristic province, lake cover, landscape, substrate chemistry and vegetation category. There is also a landscape age shapefile which was created after the publication of the CAVM (Raynolds et al. 2009) In addition, there are a number of raster maps of the same extent (the Arctic), based on satellite data from the Advanced High Resolution Radiometer (AVHRR) instruments. These include the false color-infrared and NDVI images which formed the base maps for the CAVM mapping effort (Walker et al. 2005, Raynolds et al. 2006), a recent biomass map (Raynolds et al. 2012), biomass trends (Epstein et al. 2012), NDVI trends (Bhatt et al. 2010), and Summer Warmth Index (Raynolds et al. 2008).

Differences in substrate chemistry, including pH, govern the availability of essential plant nutrients. Soils in the circumneutral range (pH 5.5-7.2) are generally mineral rich, whereas the full suite of essential nutrients is often unavailable in acidic soils (pH 7.2). The latter often have unique assemblages of plant species. The substrate chemistry map is derived from a wide variety of sources including soil, surficial geology and bedrock geology maps, and from spectral patterns that could be recognized on the AVHRR base image. Carbonate substrates occur mostly in mountainous regions, while circumneutral substrates are mostly fine-grained loess occurring at lower elevations in foothills or plains. The Alaska Arctic Substrate Chemistry Map is a more detailed map of the Alaska portion of the Circumpolar Arctic Vegetation Map (CAVM). The substrate chemistry mapping is the same as the Circumpolar Arctic Vegetation Map.

SummaryThis is the 2024 AMATS Area Boundary, showing all areas where AMATS funds can be used. AMATS coordinates transportation improvements in Anchorage. In areas with 50,000 or more people, a Metropolitan Planning Organization (MPO) works to balance transportation goals between state and local needs. AMATS is the MPO for the Anchorage region.DescriptionEvery ten years, with each census, MPO boundaries are reviewed with input from the State and local transportation operators. After the 2020 Census, the AMATS boundary was updated to include all Urbanized Areas identified by the U.S. Census Bureau. The Census defines these areas based on population density, using Block Group lines that can create uneven shapes, which don’t always fit transportation planning needs. Federal law lets States and MPOs adjust these areas for transportation purposes, making the adjusted boundary larger, but not smaller, than the Census Urbanized Areas. The AMATS area includes all of the Municipality of Anchorage except for the smaller communities of the Turnagain Arm region, including Girdwood. The gap in population density between the northern and southern sections of the area is too wide to be included in the boundary according to how census urbanized boundaries are calculated.

The landscape physiography map displays regions of plains, hills, mountains, glaciers and lakes. Generally, plains are flat or gently rolling landscapes less than 200 m above sea level. Hills are more dissected than plains (more surface roughness) and are 200-500 m in elevation. Mountains have greater surface roughness and are above 500 m in elevation.

The Zmel system (wetting area and light equipment) was established by the Act of 3 January 1986 on the development, protection and development of the coastline and by the Decree of 22 October 1991; In 2017 France adopted a national strategy based on ecosystem and economic balances. Zmel’s aim is to contribute to the sustainable development of coastal areas, reconciling the interests of recreational boating, the safety of the water body and the protection of the environment. The Zmel consists of delimiting and developing, on the natural public domain, a reception and parking area for pleasure craft. This scheme (Zmel), which is aimed primarily at municipalities and their groups, is intended to contribute to the sustainable and integrated development of coastal areas. These areas are not intended to compensate for the lack of places in marinas but can be created to absorb the so-called “wild” anchorages that illegally occupy the DPM. Distributed along the coast into four sectors and comprising a total of 10 areas, these areas, as well as any occupation of public maritime domain (MPD) dependencies, are precarious and revocable. The development, organisation and management of these areas are governed by the specific provisions of the General Code on Ownership of Public Persons and the Tourism Code. Certain provisions of the Environmental Code and, in certain circumstances, the Urban Planning Code must also be adopted. The implementation of this scheme takes account of Natura 2000 areas, entailing regulations for the mooring system adapted for the conservation of fauna such as herbarium of posidonia or other (ecological wetting).
