Description: This wetland feature class is updated daily from a python script that utilizes the data in the Wetlands_NRD feature class located in the NR_Wetlands feature dataset of the TulalipHydro geodatabase. Attributes:##The first four fields listed here are populated by ESRI software productsObjectID: Auto-populated unique identifier for each data entryShape: Auto-populated feature class typeShape_Length: Length of the perimeter of the polygon feature in the units of the projection of the layer - in this case, feetShape_Area: Area of the polygon feature in units of the projection of the layer – in this case, feet##These fields are populated using a python scriptWetland_ID: A unique identifier for each wetland and its associated ponds and lakes. River channels and estuarine subtidal polygons also each receive a unique identifier.TulalipClass: The wetland value category assigned the polygon per Tulalip Tribal Code 7.110.050 Wetlands. This field is assigned the following domain: 1 = Critical; 2 = High; 3 = ModerateWatershed: A code indicating the watershed to which the wetland polygon resides. Codes for watersheds are as follows: BAT = Battle Creek; COHO = Coho Creek; NCST = North Coastal; PORT = Port Susan; PPT = Priest Point; QUIL = Quilceda Creek; SNO = Snohomish; SPE = Spee-Bi-Dah; STU = Sturgeon Creek; TBAY = Tulalip Bay; TSHR = Tulalip Shores; TUL = Tulalip Creek; WFQ = West Fork Quilceda Creek; Other = A polygon residing in a watershed other than one of those listed aboveAcres:Area of each polygon feature in acresBuffer_ft: The width of zone contiguous with the sensitive area polygon (wetland, pond, or lake) that is required to protect and maintain the functions and structural stability of the wetland or aquatic system. This field is associated with the Tulalip Class with values assigned to the polygon per Tulalip Tribal Code 7.110.070 Buffers.Feature_Type: A designation of the general feature type. This field is assigned the following domain: P = Pond; L = Lake; FW = Freshwater Wetland; ES = Estuarine Subtidal; EI = Estuarine Intertidal (a.k.a. Estuarine Wetland); RC = River Channel; O = Other

Description: This dataset includes wetlands surveyed and mapped as part of the following projects: PDS County Stream and Wetlands Survey (1986), and the PW/SWM Drainage Needs Report completed in 2002.Snohomish County initiated the Drainage Needs Report (DNR) Program in 2000 as 'a comprehensive, two year program to assess impacts from surface water runoff in urban Snohomish County and develop a list of construction and acquisition projects that solve drainage problems, improve salmon habitat, improve water quality and predict the impacts of development.This dataset contains polygons that represent the basic wetlands categories used in the Snohomish County Stream and Wetlands Survey. The original Wetlands information was compiled in 8-86 from field studies conducted by Snohomish County Biologists. These polygons were created through Heads-up digitizing a scanned image of the original hard-copy (Mylar) maps. The sections were registered to the survey control points used in the Integrated Land Records database. Stream information was not included at this time, as funding was provided only for wetland conversion. Original scanned images exist as well as the initial registered images, which may be used for future conversion of the non-converted data.QAQC standards were developed to meet designations defined by the Buildable Lands Fund. Some polygons were moved where they intersected with existing right-of-ways upon initial creation of the wetland atlas in 1986.Wetland locations in the dataset are approximate. All wetland areas within this dataset should be surveyed before land use changes are made.
