Abstract:
This polygon data represents the locations of wetlands in the City of Lakewood and immediate area.
Purpose: This dataset was created for City of Lakewood use.
Supplemental_Information:
The wetland analysis was conducted using existing dtm surfaces provided by Pierce County and/or participating Cities. Primary sources include points and breaklines provided by Triathlon; points and breaklines provided by Pierce County from Surface Water Management aerial topography; points and breaklines from the City of Lakewood provided through Pierce County. The soil Map layer and the County Wetland Inventory layers from Pierce County GIS data were used. Orthophotos were provided by Pierce County.
The dtm surfaces were analyzed using Terramodel to identify depression or sink areas and their tributary drainage basins. This analysis located areas that are likely to have hydrologic regimes that will support wetlands. These areas were then visually analyzed in conjunction with soil mapping information and vegetative cover from the color orthophotos to determine locations and edges of probable wetlands.
These probable wetlands were then compared to the existing Pierce County Wetland Inventory layers which designate wetlands as either delineated, unverified, or verified. The delineated wetlands were georeferenced using the orthophotos to correct for improper location due to the inaccuracies in the parcel coverage. The unverified and verified coverage areas were also analyzed, and the final wetland areas and edges were converted to shapefiles.
Existing surveyed wetland edges from selected sites were imported into the computer model, and the locations were compared to the modeling results above. Corrections were applied to the shapefiles as required, and differences were analyzed to improve the modeling methodology.
Data created 2002-2003.
