Storm Water Maps

Land Use Map
This map is based on an interpretation of the 2004 Light Detection And Ranging (LiDAR) imagery data conducted by the University of Vermont's Spatial Analysis Lab for most of Chittenden County. The information has seven land use classes: Tree Canopy, Grass or Shrub, Bare Soil, Water, Buildings, Roads, and Other Paved Surfaces. The town has 8% of its Land Use in the built-on classes. Please view the Colchester Land Use Map (PDF).

Impervious Surface Map
This map illustrates the percentage of impervious surface by subwatershed. An impervious surface does not allow water to pass through it (for example, pavement) and can cause water quality problems.

The data came from further interpretation of the 2004 LiDAR imagery data conducted by the University of Vermont's Spatial Analysis Lab for most of Chittenden County. The following Land Use classes were assigned impervious class:
  • Buildings
  • Other Paved Surfaces
  • Roads

Land Cover Map
This map illustrates land cover from the 2009 Land Cover for Vermont developed by the United State Department of Agriculture's National Agricultural Statistics Service (NASS). There are 27 detailed land cover types classified within the town's watersheds. Please view the Colchester Land Cover Map (PDF).
