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. Some districts are under the purview of the Tisbury Board of Health. One may need to consult those regulations as well.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.

For planning purposes, this map shows the Right of Way bounds, Scenic Roads, and Overlay Zoning Districts of Special Ways and Major Roads Zone in West Tisbury MA. The Right of Way bounds are per the FY21 Parcel Data compiled by CAI Technologies. The Overlay Zoning Districts are compiled by the Martha's Vineyard Commission. See the data layer's attribute table for details. The Scenic Roads are from the MassGIS/MassDOT centerline road file of 2003. The MVC extracted the respective roads from that dataset in 2005.These data are NOT survey-grade. The data are provided for general planning purposes only.

Sidewalks Tisbury MA is a simplified version of 'Road Centerlines with Sidewalks' (see those process descriptions below.)The Road Centerlines with Sidewalks were dissolved based on Street Name and the side of the road the sidewalk was on. Once roads were dissolved, 'copy parallel' was used to create the line segments representing the sidewalks. Sidewalks were offset 10ft from the centerline of the road. These data are just for visual representation for use on planning maps. This file contains both the Road Centerline and the Sidewalk representations to provide flexibility with visual display. ...depending on map scale, one may work better than the other.The initial compiling of Road Centerlines with Sidewalks.DOT Year End data obtained on 6/16/2022 from https://gis.massdot.state.ma.us/arcgis/rest/services/Roads/RoadInventoryHistory/MapServer by loading it into ArcPro, filtering for Dukes County, and then using the tool Feature Class to Feature Class. Only where a non-null or non 0 value was entered for Left Sidewalk Width or Right Sidewalk Width were retained. If needed, additional segments were added from the '22 or '17 DOT road centerline file. Side walk exists if the value for Left or Right is >0. A value of 99 was entered by MVC if sidewalk is present but width unknown.A width of > 0 but < 99 was determined by MassDOT. No field verification has been performed to validate sidewalk widths. Width is reported in feet.'Left', 'Right', or 'Both' indicates the side of the road where the sidewalk is present. Side of the road is relative to the segment's From/Start - To/End delineation. All sidewalks are represented by the road's centerline.

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.

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.

Level 3 Parcel Data Standard Compliant parcel boundaries for Tisbury, MA. A 1-M relationship class exists from the parcels to the Assess table and from parcels to the Building table.The building table is an additional table (not part of the Level 3 Standard). Building info was provided by the Town assessor in late 2019/early 2020.

MassGIS Level 3 Parcel Data: Data Fiscal Year: Aquinnah 2019, Chilmark 2020, Edgartown 2021, Gosnold 2015, Oak Bluffs 2021, Tisbury 2021, West Tisbury 2021.Building Info Table: Acquired by MVC from Town Assessors in FY20.Downloaded from MassGIS,, this polygon file represents the parcel bounds for the 7 towns in Dukes County MA (Aquinnah, Chilmark, Edgartown, Godnold, Oak Bluffs, Tisbury, West Tisbury). Each town has their own parcel data consultant and then the data are forwarded to MassGIS for final processing. All data comply with the MassGIS Level 3 Parcel Data Standard. This file geodatabase only includes the TaxPar feature class and Assess table for each town. All TaxPar feature classes were appended into one feature class (Parcels_duk) by the MVC.Each assess table is utilized in that town's respective relationship join (1 to Many) for linking the parcel polygon to the related record(s) in the Assess table. The Assess Table contains info about ownership and assessed values. This is not a detailed building table. If there are multiple owners associated with a property, then the Assess table will have multiple records for that property/parcel (such as for condo parcels).Each building table is utilized in that town's respective relationship join (1 to Many) for linking the parcel polygon to the related record(s) in the Bldg table. The Bldg (building) table contains info about each building on the parcel (such as number of bedrooms, number of bathrooms, the living area square footage, etc.). NOTES of CAUTION: The Living Area Square Footage may not represent the exact same thing in each town. As a generalization, Living Area is interior space that is heated. Regarding West Tisbury, their building table only contains info for one building on the parcel. It is uncertain at this time if the info is the most recent, most primary, or some kind of summarization where multiple buildings on a parcel exist.The field of [assess_mYB] represents the Minimum/Earliest Year Built for any building on the parcel and is appended to the TaxPar feature class based on an analysis of the info provided in the building table. This field [assess_mYB] is utilized in the Historic Structures App found in ArcGIS OnLine.

Coastal District compiled from various data sources in 2011 by the Martha's Vineyard Commission. This boundary is a GIS digital representation of the boundary and reflects, to the best degree possible, the written description given the Town's zoning bylaws. However, the written description is the legal description and this GIS data is strictly for planning purposes.

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'sVineyard Commission and adopted by the town at town meeting.

The boundaries are not survey-grade and are intended for planning purposes only.

Feature layer generated from running the Join Features solution

Land use for the following watersheds: Chilmark Pond - Upper & Lower, James Pond, Menemsha Pond, Squibnocket Pond, and Tisbury Great Pond.Land use is based on assessor's use code (the first code that joins from the M*_Assess table to the M*_TaxPar feature class). The use codes have been generalized based on the methodology used in earlier Mass Estuaries Reports (MEP). West Tisbury data is FY21, Chilmark data is FY20, Aquinnah data is FY19. These are the latest parcel datasets available from MassGIS data portal as of 4/2021.Existing building count is based on MassGIS Structures having a roof square footage > 400. Future potential building count was modeled using CommunityViz software based on the most recent parcel bounds (year varies by Town; range is FY19 to FY21), minimum parcel size & road setback per town zoning (as compiled by the MVC in 2008), and existing buildings (MassGIS roof area > 400sq ft). No areas were prohibited from future development. Post-modeling, the MVC eliminated future buildings that overlapped with current open space/conservation land (per MVC & Island Conservation Partnership 4/2021).Major watershed boundaries are those created through the MEP modeling process (SMAST & MVC 2014).

This is a regulatory data layer. If your project falls within a Priority Habitat area, your project may need further review by Natural Endangered Species Program (NHESP). Please see the MassGIS website for full details.The original state-wide Priority Habitat data layer was intersected with the 3-mile limit town bounds for all towns within Dukes County. The town boundary lines are not survey-grade.

In ArcGIS OnLine an active join (one to many) was created between each town's parcel bounds and related assess table. In ArcPro those 6 joined layers were merged together into one feature layer. This file provides faster response time in web apps that permit filtering the data. The properties of the layer are set in such a way that the boundaries will not appear on the map until zoomed in.Please note: Any building related information associated with the parcel may or may not represent ALL buildings on the parcel.All parcel data meets the MassGIS Level 3 Parcel data standard. Each town has a parcel data consultant (either CAI Technologies or CGIS) who compiles their parcel bounds and export assessing data. All users are encouraged to read the 'attribute' section of the MassGIS metadata so there is clear understanding as to what these data represent.
