Description: Guilford's Parcels were adjusted in 2015 as a part of the State of Connecticut’s Policy Intergovernmental Policy Division grant to the Southern Connecticut Regional Council of Governments for the Regional Web-Based GIS program project. The parcels are constructed using an NEGEO cadastral schema which will apply for SCRCOG regional website.The Brodie Group of Guilford, CT started the development of the parcels in 2004. The primary method used was the digitization of the paper assessor maps and was created in the NAD 83 State Plane coordinate system. The basemap data used was aerial imagery produced from a fly-over by the Regional Water Authority. Updates are done on an as needed basis by town consultants.Last update: May 2015

Description: Impervious Cover by Watershed Basins is based on the Connecticut Drainage Basins layer and is 1:24,000-scale, polygon feature data that define natural drainage areas in Connecticut and contain values for calculated impervious cover (2012) within each basin. Drainage basins have been clipped to the Connecticut state boundary as well as each municipal boundary. The features are small basin areas that make up, in order of increasing size, the larger local, subregional, regional, and major drainage basin areas. Impervious Cover by Watershed Basins includes drainage areas for all Connecticut rivers, streams, brooks, lakes, reservoirs and ponds published on 1:24,000-scale 7.5 minute topographic quadrangle maps prepared by the USGS between 1969 and 1984. Data is compiled by the Connecticut Department of Environmental Protection (CT DEP) at 1:24,000 scale (1 inch = 2,000 feet). Basin delineation information is not updated. Each basin area (polygon) feature is outlined by one or more major, regional, subregional, local, impoundment, or river reach boundary (line) feature. These data include 9580 basin areas (polygons), clipped to the boundaries of Connecticut’s 169 municipalities. Impervious cover for each basin area has been calculated from 1-foot impervious cover data (link to metadata). Basin area attributes for imperviousness included total impervious area (acres), percent impervious area, building impervious area (acres and percent), roads (acres and percent) and other impervious area (acres and percent). Road impervious area has also been summarized for state (DOT) road area and non-state owned road area. Basin area (polygon) attributes include major, regional, subregional, local, (full) basin number, and feature size in acres and square miles. The full basin number (BASIN_NO) uniquely identifies individual basins and is up to 13 characters in length. There are 9580 unique basin numbers. Examples include 6000-00-1+*, 4300-00-1+L1, and 6002-00-2-R1. The first digit (column 1) designates the major basin, the first two digits (columns 1-2) designate the regional basin, the first 4 digits (columns 1-4) designate the subregional basin, and the first seven digits (columns 1-7) designate the local basin. Note, there are slightly more basin polygon features than unique basin numbers primarily because a few water supply watershed boundaries split a basin into two polygon features at the location of a small dam or point of diversion along a stream. Unique basin ID fields (BasinNoU and T_Basin_ID) have been added for the purposes of calculating impervious area. Connecticut Drainage Basins is the data source for other digital spatial data including the Connecticut Major Drainage Basins, Connecticut Regional Drainage Basins, Connecticut Subregional Drainage Basins, and Connecticut Local Drainage Basins.
Copyright Text: Tom Nosal, State of Connecticut, Department of Environmental Protection, for the final compilation and delineation of 1:24,000-scale drainage basin boundaries, assignment of drainage basin numbers, and conversion to digitial format. Basin boundaries were manually delineated at 1:24,000-scale by visually interpreting the 10 feet contour elevation lines and waterbody features appearing on 1:24,000-scale 7.5 minute USGS topographic quadrangle maps for Connecticut published between 1969 and 1984. The metadata abstract includes a brief description of a drainage basin obtained from material written by Jim Murphy in an article entitled Reading the Landscape published in the Citizen's Bulletin, a CT DEP monthy magazine.
University of Connecticut, Center for Land use Education and Research (CLEAR) clipped the basin boundaries to the state of Connecticut and municipal boundaries and calculated all impervious area values.
