Description:



            This layer shows wetlands in Newton - originally mapped by the state Department of Environmental Protection.Some wetland boundaries have been updated from site visits and/or LiDAR data



The wetlands shown in this data layer are for planning purposes only. Wetlands boundary determination for other purposes, such as the Wetlands Protection Act MA Act M.G.L. c. 131 or local  by-laws, must use the relevant procedures and criteria.




Features and Attributes:

 

            This polygon layer contains some of the attribute fields from the MassGIS layer. Unlike some of the other layers, MassGIS has a field for the descriptions of each wetland type code. Therefore there is not a domain set up and coded values do not need to be listed. A full listing of all codes and values appears in the MassGIS documentation. Only a small set up the state’s listed wetland types appear in Newton.
