  8. Title: MassGIS 2003 Massachusetts Highway Department Roads (December 2002)

    Contributors:

    Summary: This datalayer represents linework from the USGS 1:100,000 Roads Digital Line Graphs (DLGs) with additional linework from the Massachusetts Highway Department (MHD). Many of the new roads were provided to MHD by municipalities on various town-scale maps. Also, MHD made edits to existing DLG features, in many cases using the MassGIS 1:5,000 digital orthophotography as a backdrop to better spatially position the linework. In addition, this layer includes extensive attribute information maintained by the MHD which has been linked to all features. The layer is up-to-date through 2001. By late 2003 the linework in this datalayer will be replaced with 1:5,000 Road Centerlines that were interpreted as part of the Digital Orthophoto development project. The MHD inventory and street attribute data will then be attached (conflated) to the larger-scale mapping.

  14. Title: MassGIS 2003 Massachusetts Cape Cod Non-potential Drinking Water Source Areas (March 1997)

    Contributors:

    Summary: This datalayer contains polygons representing Non-Potential Drinking Water Source Areas (NPDWSA) for Cape Cod, Martha's Vineyard, Nantucket, and the Elizabeth Islands, Massachusetts. For the purpose of identifying areas in which clean up of hazardous waste sites must meet drinking water standards, as defined in the Massachusetts Contingency Plan (MCP) (310 CMR 40.0000), the DEP has coded polygons within the aquifer coverage to identify 'Non Potential Drinking Water Source Areas' (NPDWSAs). NPDWSAs include any Potentially Productive Aquifer or portion thereof which underlies land areas of at least 100 acres developed for one or more of the following uses as of January 1, 1996: Industry; Commerce; Dense residential development and associated uses; Transportation; or Urban open space; and those portions of Potentially Productive Aquifers that underlie US Census block groups with population densities of greater than 4,400 persons/square mile. Polygons for which the item NPDWSA = 1 are designated as NPDWSAs; those coded 0 for NPDWSA are not designated as NPDWSAs. As defined in the MCP, a Potentially Productive Aquifer means all aquifers delineated by the USGS as high or medium yield, and all aquifers located east of the Cape Cod Canal (Cape Cod), on the Elizabeth Islands, on Martha's Vineyard, or on Nantucket. NPDWSA polygons were delineated by the DEP based on land use information in the MassGIS land use coverage and population density data from the 1990 US Census. Municipalities were given the opportunity to review the DEP's delineation of NPDWSAs prior to the September 1996 promulgation of the current MCP groundwater clean up regulations. The delineation of NPDWSAs may reflect additional land use information provided by municipalities.

  15. Title: MassGIS 2003 Massachusetts bicycle trails (January 2003)

    Contributors:

    Summary: This dataset, formerly named 'Rail Trails,' was created by the Massachusetts Department of Environmental Management for the purpose of regional planning and mapping. In 2002 the layer was updated and renamed 'Bicycle Trails'. The linework in this layer represents trails which all permit bicycle travel or corridors with conversion potential; however, bicycles are not the exclusive travel mode permitted on these trails. The manager or owner of the trail should be contacted for detailed information about the permitted uses and rules of conduct that are specific to that trail. Most such corridors use, or connect to, old railway lines. Many of the trails represented in this layer are open to some combination of activities such as walking, jogging, rollerblading, skiing, horse riding, snowmobiling, etc., as well as bicycling.

  20. Title: MassGIS 2003 Massachusetts NHESP Potential Vernal Pools (December 2000)

    Contributors:

    Summary: This datalayer identifies the locations of more than 29,000 potential, unverified, vernal pool habitats. Vernal pools are small, shallow ponds characterized by a lack of fish and annual or semi-annual periods of dryness. Vernal pool habitats are extremely important to a variety of wildlife species, including some amphibians that breed exclusively in vernal pools, and other organisms such as fairy shrimp which spend their entire life cycles confined to such locales. Potential vernal pools visible on aerial photographs were interpreted and included in this layer. However, this datalayer does not include every vernal pool in Massachusetts. Many vernal pools have not been identified due to unfavorable conditions in the landscape topography, pool physiography and/or photograph quality. Furthermore, vernal pool habitats occur in a wide variety of landscape settings, including forested swamps, bogs, and other wetlands. Vernal pools within these settings were not typically interpreted, but are nonetheless legitimate and valuable vernal pools. Also, field verification of all potential vernal pools in this study will identify errors such as the inclusion of features that are not actually vernal pools. Potential vernal pools identified in this survey are not to be confused with Certified Vernal Pools. Data pursuant to the official 'Guidelines for the Certification of Vernal Pool Habitat' must be collected in the field and presented to the Massachusetts Natural Heritage & Endangered Species Program to obtain official certification for a vernal pool. Potential vernal pools identified in this survey do not receive protection under the Massachusetts Wetlands Protection Act Regulations (310 CMR 10.00), or under any other state or federal wetlands protection laws.
