Description: This is a combined version of the wetlands delineation completed for Midas Gold for the Stibnite Gold project for field seasons 2011 - 2019. This dataset includes wetland delineations conducted from 2011 to 2017 by HDR Engineering, Inc. and from 2018 to 2019 by Tetra Tech. This delineation was conducted in specific locations for specific purposes and should not be considered a complete delineation for the entire project area. Please check the wetlands reports submitted annually for a description of the specific area for which delineation was completed.Tetra Tech added fields- TTAA_Index-[unique number assigned to each Assessment Area Index number updated by Tetra Tech in January, 2021], TTAA_Name-[Unique descriptor of the general location of the Assessment Area using terms that describe geographic location or proximity to project facilities, Name of Assessment Area from 1/2021Tetra Tech update], TTJurisdictional_Determination-[USACE jurisdictional determination], TTSource-[Documents that convey the Jurisdictional Determination], TTWetlandName-[Updated wetland name used for joining spreadsheets], TTHydrologic_Connection-[Notes from the results tables from the Wetland Resources Baseline Study Report and Addendums], TTWetlandType-[Updated wetland type with attributed 2015 type via aerial photo interpretation], TT_ID-[Unique number assigned to each wetland polygon], TTWetlandSort[TTWetlandName attribute with zero padding to correct alpha-numeric sorting).This dataset was modified in 1/2021 and was designed to display areas within wetlands that are occupied by stream channels. Streams and wetlands are analyzed separately within the compensatory mitigation framework. The stream channel features will be discussed and analyzed in the RioASE 2021 Stream Functional Assessment Report, while the wetland portions will be discussed and analyzed in the Tetra Tech 2021 Draft Compensatory Stream and Wetland Mitigation Plan. The stream channel boundaries were produced by buffering stream polylines in a combined Tetra Tech/RioASE dataset, using estimated and modeled stream widths, to form a dataset representing stream channel polygons. This dataset was then intersected with the original delineated wetland feature dataset to form a revised dataset which included the stream channel boundaries with their original attributes from both the delineated stream and wetland datasets. The stream channels were given a TTWetlandType attribute of "Stream Channel" and the TTHydrographic_Cat field contains the stream type attribute from the combined RioASE/Tetra Tech stream dataset. Analysis performed on this dataset should not count the stream channel polygons as wetland impacts, since they are already accounted for in the stream impact analyses.This dataset and metadata was last edited on 2/12/2021.
