Data Description

Environmental Data contains data for a variety of natural environmental features covering geomorphic, hydrologic and vegetative topics. The data has been symbolized and color coded with mapping parameters conveniently pre-set.

Layer File Details*

Watersheds Sub-Basin Boundaries  (metadata)
Description: This polygon feature class is a collection of watershed sub-basins found in and around the City of Bellingham.
Symbology: Watersheds sub-basin boundaries are symbolized with a hollow fill and dark grey outline based on the WATERSHEDSUBBASIN field.
Labels: None 
Definition Query: None

Creek Sub-Basin Boundaries  (metadata)
Description: This polygon feature class is a collection of watershed sub-basins found in and around the City of Bellingham.
Symbology: Creek sub-basin boundaries are symbolized with a hollow fill and dark grey outline based on the CREEKBASIN field.
Labels: None 
Definition Query: None

Watersheds  (metadata)
Description: This polygon feature class is a collection of watersheds found in and around the City of Bellingham.
Symbology: A unique pastel fill per watershed.
Labels: None 
Definition Query: None

Site Specific Wetland Delineations  (metadata)
Description: The purpose of this polygon feature class is to show the location of wetlands, derived from submitted delineation reports within the City of Bellingham general area. This feature class does NOT represent a complete wetland inventory, but only to catalog the individual wetlands from delineation reports as the City of Bellingham receives them (and therefore is not a complete or all inclusive representation of wetlands).
Symbology: A light pink fill with slightly darker pink outline.
Labels: None 
Definition Query: None

Wetland Inventory 2003
Description: 
This is a polygon feature class. In June 2003, the Northwest Ecological Services, LLC (NES) was contracted to develop a comprehensive GIS database that identifies wetland locations and other environmentally sensitive features within specified areas being considered for future urban development. The geographic scope of the project included land in and adjacent to Bellingham's Urban Growth Areas as specified by City planning staff. Wetland data is reconnaissance level data and wetland boundaries indicated on the maps are approximate and intended only to provide an indication of the presence of wetlands.
Symbology: This layer file is symbolized using the WET_TYPE field and uses a different color fill per unique value.
Labels: None 
Definition Query: None

Wetland Inventory 1992  (metadata)
Description: In 1992, contracted field technicians reviewed existing wetland and soils inventories, and interpreted aerial photographs.  Both color infrared (1" = 2,000') and black and white orthophotographs (1" = 200')  were used. Through field surveys, data was collected from over 300 potential wetland areas to determine whether each site met the criteria to be identified as a wetland based on vegetation, soils, and hydrology. The purpose of the wetland inventory is to identify the general location and character of the wetlands with the City of Bellingham.  The inventory is for orientation purposes only and is not intended to represent jurisdictional wetland boundaries. This is a polygon feature class.
Symbology: This layer file is symbolized using a light yellow fill with a light gray outline.
Labels: None 
Definition Query: None

NWI Wetland
Description:
For the NWI Wetlands, wetland location and classifications were developed by the U.S. Fish & Wildlife Service. Wetland information was derived from aerial photo-interpretation with varying limitations due to scale, photo quality, inventory techniques, forest cover and other factors. (Date ranges from Feb. 1971 to Nov. 1997)  It was not the intent of the NWI to produce maps that show exact wetland boundaries  comparable to boundaries derived from ground surveys. Boundaries are therefore generalized in most cases. This is a polygon feature class.
Symbology: This layer file is symbolized using a light pink fill with a light gray outline.

Coal Mines  (metadata)
Description: Approximate locations of mines and prospects as described in the Geologic Hazard Areas, Map Folio, Bellingham, WA 1991.  Bellingham, Sehome, Pattle, and Union mines mapped based on historic documents depicting mine entrances and layout of workings (accuracy varies).  Other mine locations mapped based on legal descriptions from claim documents.
Symbology: Light magenta polygon shade with dark magenta outline.
Labels: None
Definition Query: None

Geology (Puget Sound)
Description: Washington State Department of Natural Resources Division of Geology and Earth Resources 1:100,000-Scale Digital Geology of Washington State (100K quads covering Puget Sound Basin).  Surficial geology units for Bellingham/Whatcom County area based on work published by Tabor, Haugerud,  Booth, and Brown, 1994, USGS Open-File Report 94-403.
Symbology: Polygons symbolized based on rock classification using MAPNAME attribute.  Color scheme based on WA State Geologic Map published by WA State DNR. 50% Transparency.
Labels: None
Definition Query: None

Lake Whatcom Watershed  (metadata)
Description: Watersheds is a polygon feature class which illustrates the Lake Whatcom Watershed.
Symbology: Polygon is symbolized as a “single symbol” with the watershed boundary shown in a light blue dashed line.
Labels: None
Definition Query: A definition query has been written to return only the Lake Whatcom Watershed.

Landslides & Alluvial Fans  (metadata)
Description: Polygon feature class which represents the approximate locations of landslides and alluvial fans as described in the 1991 Geologic Hazard Areas Map Folio for Bellingham, WA.
Symbology: Polygons are symbolized by Alluvial Fans with a dotted fill and Landslides with a brown fill.
Labels: None
Definition Query: None

Potential Wave Erosion
Description: Approximate locations of wave erosion areas that are subject to erosion by storm waves as indicated by the Coastal Zone Atlas and described in the 1991 Geologic Hazard Areas Map Folio for Bellingham, WA.
Symbology: Polygons are symbolized by a light green hatched area.
Labels: None
Definition Query: None

Seeps & Springs  (metadata)
Description: Point feature class which represents the approximate locations of Seeps & Springs as described in the 1991 Geologic Hazard Areas Map Folio for Bellingham, WA.
Symbology: Points are symbolized with a single blue icon.
Labels: None
Definition Query: None

Seismic Hazard
Description:
Polygon feature class illustrates the response to Seismic Shaking by ranking areas as Low,  High, Moderately High and Very High.  Information is based on a mix of Whatcom County/USDA geology series, Geologic Hazards Areas, Map Folio(1991), and with shoreline areas around Squalicum Harbor, Whatcom Waterway and Fairhaven updated by City staff to reflect the new shoreline fill areas since publication of the USGS basemap.
Symbology: Polygons are symbolized with in shades of red based on the two highest rankings.
Labels: None
Definition Query: A definition query has been written to return only the two highest rankings.
