Phase 1 Site Assessment Map

MCP Numerical Ranking System (NRS) Site Map


The purpose of this tool is to allow a Potentially Responsible Party (PRP) or a Licensed Site Professional (LSP) to generate a Phase 1 Site Assessment Map that is suitable for printing on a standard letter ( 7.5” x 11” ) sized portrait page.

Site Information

The name, address, town and RTN information that you provide will be displayed at the top of the map. Address and or town information is also used to zoom the map to the general area of the site. Once the map opens at this initial extent you can use the Map Tools to navigate the map, locate a site and generate an MCP NRS Map. Buffers will be drawn at 500 ft and .5 mile around your site.

Massachusetts' History of Orthophotos

MassGIS Imagery Time Series

For over 25 years, MassGIS has been paying for or otherwise collecting orthophotography for Massachusetts. While MassGIS does this primarily to create an accurate basemap upon which to build and display other GIS maps, for most of the vintages of orthophotos, the general public can view and download the images. In 2020, we created a story map that explains the ortho imagery acquisition through the years and allows the reader to explore the various vintages in one location.

Statewide Property Sales Viewer

Statewide Property Sales Viewer interactive map

The Statewide Property Sales Viewer maps real estate sales assembled by the State's Bureau of Local Assessment (part of the Division of Local Services).  The source is the annual "LA3" sales reports provided by municipal assessors. On the Division of Local Services website, these sales can be searched by property type, range of sale date or price, and other characteristics. You can download the search results. This MassGIS sales viewer application supports the same search criteria and then maps the result, color coding the sales based on their assessment-to-sale ratio. You can also still see and download the tabular result.

Wetland and Wetland Change Areas

Wetland and Wetland Change Areas Map

The Wetland and Wetland Change Areas Map displays MassDEP developed wetland areas interpreted from 1:12,000 scale, stereo color-infrared (CIR) photography captured in 1990, 1991, 1992, 1993, 1999 and 2000. The map also includes Wetland Change areas interpreted from three separate iterations of MassGIS orthophotography.

The wetland and wetland change areas represented on this map have been determined solely through photo-interpretation. They do not represent, and should not be used as, wetlands delineation under the Wetlands Protection Act (M.G.L. c. 131, sec. 40) and the implementing regulations (310 CMR 10.00 et seq.).

The Wetland and Wetland Change Areas Map is scale sensitive and will only draw when the map viewer is zoomed in to an appropriate, large scale. At smaller scales only the underlying base map will be displayed.
