  10. Title: Plano de Yerba Buena, Alta California (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a site plan Plano de Yerba Buena, Alta California. For descr. see: Harlow, N. The Maps of San Francisco Bay ... 1850, no. 31.Pen-and-ink and watercolor on tracing paper.Oriented with north to right."No. 280, City of San Francisco, San Francisco, Exhibit no. 2 A.F., filed in office Aug. 20, 1853, Geo. Fisher." Shows drainage, settlements, etc. Relief shown pictorially. A scanned version of this map was georeferenced as part of the Imagined San Francisco project. This project traces the history of urban planning in San Francisco, placing special emphasis on unrealized schemes. Rather than using visual material simply to illustrate outcomes, Imagined San Francisco uses historical plans, maps, architectural renderings, and photographs to show what might have been. By enabling users to layer a series of urban plans, the project presents the city not only as a sequence of material changes, but also as a contingent process and a battleground for political power. Savvy institutional actors--like banks, developers, and many public officials--understood that in some cases to clearly articulate their interests would be to invite challenges. That means that textual sources like newspapers and municipal reports are limited in what they can tell researchers about the shape of political power. Urban plans, however, often speak volumes about interests and dynamics upon which textual sources remain silent. Mortgage lenders, for example, apparently thought it unwise to state that they wished to see a poor neighborhood cleared, to be replaced with a freeway onramp. Yet visual analysis of planning proposals makes that interest plain. So in the process of showing how the city might have looked, Imagined San Francisco also shows how political power actually was negotiated and exercised. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  12. 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.

  17. Title: MassGIS 2003 Massachusetts Interim Wellhead Protection Areas for Community Water Supply (March 2003)

    Contributors:

    Summary: This datalayer contains polygons representing Interim Wellhead Protection Areas (IWPA) for community water supply (IWPACOM) sources as defined by the Massachusetts Department of Environmental Protection. Wellhead protection areas are important for protecting the recharge area around public water supply (PWS) wells. A Zone II is a wellhead protection area that has been determined by hydrogeologic modeling and approved by the Department of Environmental Protection's (DEP) Drinking Water Program (DWP). In cases where hydro-geologic modeling studies have not been performed and there is no approved Zone II, an Interim Wellhead Protection Area (IWPA) is established based on DEP DWP well pumping rates or default values. Certain land uses may be either prohibited or restricted in both approved (Zone II) and interim (IWPA) wellhead protection areas. In the absence of an approved Zone II, DEP has adopted the Interim Wellhead Protection Area (IWPA) as the primary, protected recharge area for PWS groundwater sources. For PWS sources that pump less than 100,000 gallons per day (GPD), the IWPA radius is proportional to the pumping rate in gallons per minute (GPM). Pumping rate is determined by DEP DWP based on one of the following methods, DWP approved pumping rate, metered data or Title 5 flow rate. The formula used for calculating the PWS well point buffer radius in feet is: Radius = ( 32 x pumping rate in GPM ) + 400 The minimum IWPA radius is 400 feet, the maximum (default) radius reached at 100,000 GPD (70 GPM) is 2,640 feet (1/2 mile). In instances where DWP pumping rate information is unavailable DWP approved default radius values are assigned based on PWS well classification. The default radius for community class PWS groundwater sources (GW) is 2,640 feet (804.6 meters). The default radius for non-community sources is 750 feet (228.6 meters) for Non Transient (NTNC) wells and 500 feet (152.4 meters) for Transient (TNC) wells. The DEP GIS Program currently [2003] maintains two statewide IWPA coverages (IWPA and IWPACOM) shared through MassGIS. Both are generated by buffering groundwater sources in the DEP Public Water Supply datalayer (PWS_DEP). The IWPA coverage contains variable width IWPA buffers for BOTH approved community and non community groundwater sources in the DEP PWS datalayer which do not have an approved Zone II. The IWPACOM coverage contains IWPAs ONLY for community PWS sources which do not have an approved Zone II.

    Contributors:

    Summary: The Massachusetts Department of Environmental Protection (DEP) major facilities datalayer is a statewide point dataset containing the location of a subset of facility types regulated by DEP's Bureau of Waste Prevention (BWP). In a preliminary effort to begin locating facilities regulated by DEP, the BWP chose to locate facility types having the greatest potential environmental significance. At this time, the following facility types have been located: Large Quantity Generators of Hazardous Waste (LQG) Large Quantity Toxic Users (LQTU) Hazardous Waste Recyclers Hazardous Waste Treatment, Storage and/or Disposal Facilities (TSDF) Facilities with Air Operating Permits Facilities with Groundwater Discharge Permits

  19. Title: MassGIS 2003 Massachusetts Designated Shellfish Growing Areas (Arcs) (October 2000)

    Contributors:

    Summary: The Designated Shellfish Growing Area (DSGA) datalayer was compiled by the Department of Fisheries, Wildlife and Environmental Law Enforcement's (DFWELE) Division of Marine Fisheries (DMF). Three hundred and three growing areas in Massachusetts have been designated by DMF's Shellfish Project. The data are stored in two feature layers: Designated Shellfish Growing Areas (Arcs) and Designated Shellfish Growing Areas (Polygons). A designated shellfish growing area is an area of potential shellfish habitat, and all three hundred and three DSGA's make up the territorial waters (tidal zone out to the territorial line) of the Commonwealth. Growing areas are managed with respect to shellfish harvest for direct human consumption, and comprise at least one or more classification areas. The classification areas are the management units, and range from being approved to prohibited (six different classification types in all) with respect to shellfish harvest. For example, one growing area may be composed of four classification areas, all of which are managed separately (have a classification type the same or different from the rest in the growing area). This coverage reflects classification areas as of July 1, 2000. The dataset was originally issued in October 2000.
