To be used for reference by Brookline Planning & Community Development Department staff. Purpose of creating map was to gather all basic information necessary for zoning case review into one place. May not have the most up-to-date information so use with caution.

For planning purposes only. The overlay zoning districts within West Tisbury MA and Parcel Boundaries. These data are not survey-grade. Each overlay zoning district is presented as its own data layer - so you can turn on or off each district to have more or less clutter on the map. Please see the Town's zoning bylaws for all regulations.See the data layer's attribute table for a brief explanation of how that layer was compiled by the Martha's Vineyard Commission. The parcel bounds were created by CAI Tech. per MassGIS Level 3 parcel data standard. Parcels are fed into the map from the MassGIS ArcGIS OnLine cloud. They update the hosted parcel data typically once a year. See the FY attribute field for the respective year - last updated.

This layer represents City of Boston Zoning Subdistrict boundaries indicating geographic areas subject to specific zoning guidelines. Developed and maintained by the Planning Department GIS in accordance with the Boston Zoning Code.

Overlay zoning districts are in addition to standard town zoning. The districts' boundaries and use limitations &/or development constraints are described in the town's zoning bylaw. The MVC generated these digital spatial boundaries based on the best GIS data available at the time of processing.Some overlay zoning districts are also Districts of Critical Planning Concern. These are zoning districts established by the Martha's Vineyard Commission and adopted by the town at town meeting.The boundaries are not survey-grade and are intended for planning purposes only.

City of Woburn MA, Public Map ViewerMap many types of local data - stormwater, drinking water, parking, sewer, zoning, etc.

The data defines the locations of the various types of zoning districts as described in the Town's Zoning by-Laws, as approved at Special Town Meeting 2024.Where any uncertainty exists with respect to the boundary of any district as shown on the Zoning Map, the following rules apply:1. Where a boundary is indicated as a street, railroad, watercourse or other body of water, it shall be construed to be the centerline or middle thereof, or where such boundary approximates a town boundary, then to the limits of the town boundary.2. Where a boundary is indicated as following approximately or parallel to a street, railroad, watercourse, or other body of water, it shall be construed to be parallel thereto and at such distance there from as dimensioned on the Zoning Map. If no dimension is given, such distance shall be determined by use of the scale shown on the Zoning Map.3. Where a dimensioned boundary coincides within ten (10) feet or less with a lot line, the boundary established by records as of March 1973 shall be construed to be the lot line.4. Where a boundary is indicated as intersecting the centerline of a street, railroad, watercourse or other water body, it shall be construed to intersect at right angles to said centerline, or in the case of a curved centerline, at right angle to the tangent to the curve at the point of intersection.5. Whenever any dispute arises on district boundaries as to the exact location of a district boundary line, the location of such line shall be determined by the Planning and Zoning Board.

The MassGIS zoning datalayer represents the boundaries of municipal zoning districts. Because zoning is established at the town level, there is no standard district classification across the state. While districts in different towns may have similar or even identical names, their definitions are often quite different. Generalized codes have been added to make these data useful for regional display. A related table contains detailed information about the districts such as setbacks or text descriptions from each town’s zoning bylaws. Data are available for all communities. (Only primary district information is available for the City of Boston, not additional infomation for its bylaws.) MassGIS stores the data in a statewide ArcSDE layer named ZONING_POLY. Zoning district boundaries change frequently and MassGIS currently has no formal process in place to regularly update these coverages. These data should therefore be used for regional analysis only and not as official zoning maps. The town’s own official zoning map and current copy of the by-law should be considered as the final word on zoning boundary questions or issues. In August, 2007, data were updated for these 93 towns: Adams, Agawam, Amherst, Aquinnah, Ashburnham, Ashby, Athol, Ayer, Belchertown, Billerica, Bourne, Brewster, Chatham, Chelmsford, Cheshire, Chester, Chesterfield, Chicopee, Chilmark, Clarksburg, Clinton, Cummington, Dalton, Dennis, East Longmeadow, Edgartown, Egremont, Falmouth, Fitchburg, Gardner, Georgetown, Gosnold, Granby, Great Barrington, Groton, Hadley, Hampden, Harvard, Hatfield, Hubbardston, Huntington, Lancaster, Lanesborough, Lawrence, Lee, Lenox, Leominster, Lowell, Ludlow, Lunenburg, Mashpee, Monson, Monterey, New Ashford, North Adams, Northampton, Oak Bluffs, Otis, Palmer, Petersham, Phillipston, Pittsfield, Richmond, Rowley, Royalston, Russell, Salisbury, Sandisfield, Sheffield, Shirley, South Hadley, Southampton, Southwick, Sterling, Stockbridge, Templeton, Tisbury, Townsend, Truro, Ware, Washington, Wellfleet, West Springfield, West Stockbridge, West Tisbury, Westfield, Westminster, Wilbraham, Williamsburg, Williamstown, Winchendon, Worthington, and Yarmouth.

The zoning boundaries map layer is an integral part of the planning data in the City of Worcester Geographic Information System. This data is used by many City Departments in case review, code enforcement, and long range planning. Planning data layers are accessed by personnel in most City departments for basic applications such as viewing, querying, and map output production. More advanced user applications may focus on planning analysis, spatial analysis, presentation output, and review of proposed development. The zoning boundaries data layer is governed by ordinance and is only changed accordingly. The zoning data layer was digitized by L. Robert Kimball & Associates, Inc. as part of a data conversion project in 1995. Further updates have been made by the City of Worcester since that time to reflect ordinance changes.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

Parcel boundaries for the town of Aquinnah MA processed in 2002 by MAPC as part of the Community Development Plans. The parcel data is per the Town's parcel data consultant, CAI Technologies. The parcel data are served out by MassGIS and fed directly into this web map.

This map includes shoreline change data for the state of Massachusetts hosted by the Massachusetts Office of Coastal Zone Management.The active data layer in this map is Massachusetts Shoreline Change Transect (1970-2014) with short-term shoreline change rates. To view long-term rates, open map in Map Viewer to turn on layer.The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. The shoreline position and change rate are used to inform management decisions regarding the erosion of coastal resources. In 2001, a shoreline from 1994 was added to calculate both long- and short-term shoreline change rates along ocean-facing sections of the Massachusetts coast. In 2013, two oceanfront shorelines for Massachusetts were added using 2008-9 color aerial orthoimagery and 2007 topographic lidar datasets obtained from the National Oceanic and Atmospheric Administration's Ocean Service, Coastal Services Center. In 2018 two new mean high water (MHW) shorelines for Massachusetts were extracted from lidar collected between 2010 and 2014 (described below). 2018 addition shoreline 1The North Shore and South Coast uses 2010 lidar data collected by the U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise. The South Shore and Outer Cape uses 2011 lidar data collected by the U.S. Geological Survey's (USGS) National Geospatial Program Office. Nantucket and Martha’s Vineyard uses 2012 lidar data collected by the USACE (post Sandy)from a 2012 USACE Post Sandy Topographic lidar survey. 2018 addition shoreline 2The North Shore, Boston, South Shore, Cape Cod Bay, Outer Cape, South Cape, Nantucket, Martha’s Vineyard, and the South Coast (around Buzzards Bay to the Rhode Island Border) is from 2013-14 lidar data collected by the (USGS) Coastal and Marine Geology Program. This 2018 update of the rate of shoreline change in Massachusetts includes two types of rates. Some of the rates include a proxy-datum bias correction, this is indicated in the filename with “PDB”. The rates that do not account for this correction have “NB” in their file names. The proxy-datum bias is applied because in some areas a proxy shoreline (like a High Water Line shoreline) has a bias when compared to a datum shoreline (like a Mean High Water shoreline). In areas where it exists, this bias should be accounted for when calculating rates using a mix of proxy and datum shorelines. This issue is explained further in Ruggiero and List (2009) and in the process steps of the metadata associated with the rates. This release includes both long-term (~150 years) and short term (~30 years) rates. Files associated with the long-term rates have “LT” in their names, files associated with short-term rates have “ST” in their names.

WHAT IS THIS TRACKER FOR?

The City of Boston is committed to increasing transparency in the processes around the Zoning Board of Appeal (ZBA). The Inspectional Services Department (ISD) at the City is tasked with ensuring compliance with the zoning code. If an application for a permit is refused because of a zoning violation, applicants are able to appeal the decision to the ZBA and ask for an exception, sometimes known as a “variance.” If the ZBA grants relief, then the appellant is able to continue with the process of obtaining a permit.

In order to provide greater transparency in the ZBA process, the City of Boston Zoning Board of Appeal tracker is now available on Analyze Boston. Each record in this tracker represents an appeal of a denied permit application; the original permit application is known as the “parent application.” To find out more information about the original permit application, visit our Permit Finder tool. To view a map of this data, visit our ZBA Tracker Map Tool.

To learn more about the ZBA process and how to file an appeal, visit our website.

WHAT DOES EACH STATUS MEAN?

Appeal Submitted - indicates that an appeal of a zoning refusal was successfully submitted into ISD’s tracking system, either in-person at ISD (1010 Massachusetts Ave.) or through the online application portal.

More Information:

• For detailed information on how to file an appeal, see this page on the ISD website.

Next steps:

• The appeal will undergo an initial review by City staff to ensure that all necessary information and documentation has been included.
• The appellant must pay a fee.

Community Process - indicates that City staff have completed their review and signed off for the appeal process to move onto getting community feedback.

Contact Information:

• Use the link below to find the Neighborhood Liaison from the Office of Neighborhood Services for the application’s location.

Next steps:

• The appellant will work with the Mayor’s Office of Neighborhood Services to engage with people who own adjacent properties, members of the local community, and other relevant stakeholders.

• Depending on the type of project, the Boston Planning and Development Agency may also conduct a review.

Hearing Scheduled - indicates that the appeal has been scheduled for a committee or subcommittee meeting of the ZBA. For this to take place, the Mayor’s Office of Neighborhood Services has notified ISD that the appellant has adequately engaged with the community that would be affected, should the zoning relief be granted.

Attendance Information:

• View a schedule of hearings at the ZBA webpage. Select an Upcoming Hearing to find the list of topics and how to attend.

Next steps:

• The appellant will attend the hearing in person (or through the virtual meeting). The appellant will provide the ZBA with reasons why an exception or variance to the zoning code should be granted and answer any questions from the ZBA.

• At the hearing, members of the public will be able to testify in support or against the appeal.

• The ZBA will discuss the appeal and vote to approve or deny.

Alternatively:

• The appellant can request a deferral; if allowed by the ZBA, during the hearing the appeal will receive a new hearing date.

• The appellant can withdraw the application; if allowed by the ZBA, it can be withdrawn without prejudice.

Hearing Rescheduled - indicates that the appeal’s scheduled committee meeting has been changed. This can happen for several reasons. For example, the appellant can request a deferral if they need more time to complete or update plans, or the board can defer an appeal if a quorum isn’t present (perhaps due to a recusal). A request for deferral is approved by the board, which also selects a new hearing date.

Next steps:

• Same as Hearing Scheduled above.

Hearing Concluded - indicates that the hearing has taken place. The appeal could have been approved, denied, deferred, or withdrawn, with or without additional requirements.

Additional Information:

• Meeting minutes from each committee meeting are available to download from the ZBA webpage.

Next steps:

• The ZBA Executive Secretary finalizes the Board’s decision in writing or the appellant’s attorney submits a finalized decision for ISD Legal Team review.

ZBA Decision Finalized - indicates the date on the ZBA’s written decision letter. The decision is listed under the ‘result’ field.

Next steps:

• Neighboring property owners are notified of the decision shortly after this date

• Beginning on the Final Decision Date, neighboring property owners and other involved parties who disagree with the ZBA’s decision have twenty days to file an appeal in Suffolk County Superior Court or Boston Housing Court. (For detailed information on the Zoning Commission and appeal process, please refer to Chapter 665 of the Acts of 1956, available here)

Appeal Closed - indicates the appeal’s outcome has been finalized and the twenty day Appeal period has ended.

Next steps:

• Depending on the ZBA decision, the appellant may or may not be able to continue the process for seeking the permit for which zoning relief was requested.

• If the ZBA approved or sustained with proviso, the appellant must take additional steps before continuing the permitting process.

WHAT DOES EACH RESULT MEAN?

Approved - means the zoning relief requested has been granted.

Approved with Proviso - means the zoning relief requested has been granted, with some conditions that must be fulfilled before the permitting process can continue. These conditions will be detailed in the written decision of the ZBA. Examples of such conditions could include: having the Boston Planning and Development Agency review updated plans; submitting more detailed plans; or obtaining additional engineer reports.

Denied - means the zoning relief requested was not granted. The appellant must wait a year before submitting a new appeal on a project for the same site.

Denied without Prejudice - means the zoning relief requested was not granted. However, the appellant only has to wait thirty days before submitting an appeal on a new project at the same site.

Withdrawn - means the appellant has chosen to remove the appeal from the ZBA’s consideration. The appellant does not have to wait a year to appeal the same zoning violations.

Note: If there is no result listed, it means that the ZBA has not issued its final written decision on the appeal. This may be the case even for appeals that have been heard by the ZBA.

The Tisbury zoning GIS feature layer was created from on-screen digitizing of the 'official' Tisbury Zoning map to the FY20 parcels. The GIS work was completed by the Martha's Vineyard Commission. The 'official Tisbury Zoning map' was created by Schoefield Barbini & Hone to the best of their ability based on the information they had at that time. This Zoning layer does not include Overlay Zoning Districts &/or Districts of Critical Planning Concern.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).
