Description: The high-resolution impervious surface dataset for the Lake Champlain Basin (Vermont and New York) developed by the UVM Spatial Analysis Lab in 2011, and used in the development of the Vermont Lake Champlain Phosphorus TMDLs (2016) was applied to generate estimates of the VTrans Phosphorus Control Plan Area, through consultation with the Agency of Natural Resources Stormwater Program. A feature dataset was developed to represent the VTrans Right of Way (ROW) using a combination of data sources and manual editing. First, ROW data from VTrans was obtained. The dataset was incomplete in some areas. To supplement the VTrans ROW dataset, the MATS road centerline data was buffered by 50 ft for interstates and 25 feet for other VTrans roads and added to the overall ROW dataset. For purposes of stormwater management and improvement for the TS4 permit, only ROW areas maintained and owned by VTrans are of interest. ROW areas on municipally or privately owned property, with a focus on impervious surface areas, were removed from the final dataset, where feasible. Once areas owned and controlled by VTrans within the Vermont Lake Champlain Basin were identified, VTDEC applied the GIS datasets defining the TS4 extents within the LCB to extract draft developed lands acreages and resulting draft phosphorus base loads from VTDEC’s existing developed lands dataset. The draft acreages and phosphorus base loads were broken down by lake segment, SWAT model drainage area, type of area (Road/linear facility or Parcel-based facility) and type of land use/land cover (Developed Impervious, Paved Road, Unpaved Road, and Developed Pervious). Draft phosphorus base loads and target reductions were provided in draft form by VTDEC on January 12, 2018. Following consultation with VTrans and adjustments to the draft acreages and phosphorus base loads, the final dataset was delivered by VTrans and Stone Environmental to ANR in March 2018. This dataset summarizes the March 2018 deliverable by SWAT drainage area, area type (road or facility), and land cover.
