Wetlands (MassDEP) and Parcels - Dukes County

The wetlands data (linear and area features) presented in the map for Dukes County were obtained from MassGIS and published by MassDEP (pub. 2017 - still most current available as of Feb. 2025). See MassGIS website for methodology details. The parcel data are those hosted by MassGIS and have been filtered to only show those parcels within Dukes County. Please refer to the respective websites to understand the level of accuracy and use constraints associated with these datasets. The stream, intermittent stream, and wetland area buffers (100ft and 200ft) were processed by the Martha's Vineyard Commission in Jan. 2025 from the MassDEP wetlands data. This web map was compiled by the Martha's Vineyard Commission for planning purposes only. The parcel data will appear once zoomed-in on the map.
