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.

The Martha's Vineyard Commission, in varying years, has joined the town water department customer list to the parcel boundary file. Data includes:Edgartown - Year 2008 (water records & parcel boundaries)Chilmark (Menemsha) - Year 2004 (water records & parcel boundaries)Oak Bluffs - Year 2017 (water records; parcel boundaries FY19)Tisbury - Year 2016 (water records; parcel boundaries FY19)The towns of Aquinnah and West Tisbury are fully served by individual private wells. In Chilmark, it is only the Menemsha village which is served by the Menemsha Water Company. Those parcels NOT served by town water in Edgartown, Oak Bluffs, & Tisbury are served by individual private wells.

Most of the properties on Martha's Vineyard have their septic tank to collect/treat their wastewater. Some properties in Edgartown, Oak Bluffs, and Tisbury are served by a municipal wastewater treatment facility. The MVY Airport and Wampanoag Tribal Housing area are served by an on-site wastewater treatment systems.The municipal wastewater treatment customer records were joined to the parcel boundaries to produce this spatial coverage.Edgartown (2019 - Wastewater records & FY19 Parcel boundaries)Oak Bluffs (2016 - Wastewater records & FY19 Parcel boundaries)Tisbury (2017 - Wastewater records & FY19 Parcel boundaries)

This dataset consists of 2-dimensional roof outlines ("roofprints") for all buildings larger than 150 square feet, as interpreted by a contractor (Rolta) for the whole area of the Commonwealth using DigitalGlobe ortho images obtained in 2011 and 2012, supplemented with LiDAR (Light Detection And Ranging) data collected from 2002 to 2011 for the eastern half of the state. The roofprints as delivered were enhanced by MassGIS using Normalized Digital Surface Models (NDSMs) derived from the same LiDAR data. Other layers were used, including the Level 3 Parcels, to aid in review, especially where LiDAR data were not available.This feature class is being updated using ortho imagery captured in 2013, 2014 and 2015. The newer imagery allows MassGIS staff to remove, modify and add structures to keep up with more current ground conditions. Structures from the original compilation that are removed are stored in an "archive" feature class for edit tracking and historical purposes.Last updated on 5/22/2017.In ArcSDE the layer is named STRUCTURES_POLY.

Town zoning districts for all 7 towns within Dukes County MA. These zoning extents have been mapped over the years (starting in the early 2000s) based upon written descriptions in the town's bylaws. A variety of basemap references and vintages have been used to map the extents of these zones. Data are for planning purposes only and are not survey-grade.This web map also contains Tisbury's "Management Areas" within their Waterfront/Commercial District. These sub-areas are described in detail in the Town's zoning bylaws.The Dukes County Towns include: Aquinnah, Chilmark, Edgartown, Gosnold, Oak Bluffs, Tisbury, and West Tisbury.The Martha's Vineyard Commission makes all efforts to keep these data up to date and as accurate as possible. Please contact the MVC if you believe the data contain inadvertent errors or omissions. The date of last GIS edit is contained within the attribute table of the zoning data.The parcel data are served out by MassGIS and updated by the Town's parcel data consultant. The MVC does not edit or maintain parcel data for any of the Dukes County Towns.

This feature layer contains a zoning layer for each of the 7 towns within Dukes County MA. Most of the data was compiled by the Martha's Vineyard Commission. Older data was created by MAPC staff during the Community Development Plan project in the early 2000s.See dataset's attribute table for last edit date. The date range for edits is wide: 2003 to 2024. The basemap of reference, in some cases (Tisbury) was the current GIS parcel boundary file at time of editing. The other towns seaward extent of zoning will not match the parcel data bounds since a different basemap was referenced at time of editing. The ZoneCode attribute contains the abbreviated zoning name for each district, preceded by the town's ID number.For Zoning Bylaws, see each Town's bylaws website: Aquinnah Chilmark Edgartown Gosnold Oak Bluffs Tisbury West Tisbury

NOTE: Harvard Forest did not provide written metadata. Rather, this metadata was written by the Martha's Vineyard Commission based on a phone conversation with Harvard Forest staff in Dec. 2023.Utilizing Harvard Forest's "Ancient Woodlands" data of 2019, the Martha's Vineyard Commission ran the Identity geoprocessing tool with that dataset and the MVC's 12/22/2023 version of the Open Space Conservation data for Martha's Vineyard. This process retained all of the Ancient Woodlands data and superimposed the attributes of [Level of Protection] and [OS_ID] into the Ancient Woodlands polygons. This permits one to readily analyze the data to see where Ancient Forests are currently protected in perpetuity, etc. Please see the Description section for background about Harvard Forest's delineation of the Ancient Woodlands.A domain table is provided which explains the Level of Protection codes. The [OS_ID] is a numeric ID which links back to the MVC's Open Space Conservation dataset. OS_ID is a unique identifier within that dataset. The numbers before the hyphen is the Town ID. 62 = Chilmark, 89 = Edgartown, 104 = Aquinnah, 221 = Oak Bluffs, 296 = Tisbury, 327 = West Tisbury.The Ancient Woodlands data were produced by Harvard Forest in Dec. 2019. Data for Martha's Vineyard were received from Harvard Forest in November of 2023. Looking at historic maps and older aerial photographs, Harvard Forest noted for 4 time periods when forest was present on the map or photo. Locations where forest was present for all 4 time periods, were regarded as 'Ancient Woodlands'. The 4 time periods reviewed were: circa 1850, circa 1890, 1938, 1993. Then the data were updated, based on Google's November 2018 photos, for recent development or new agricultural areas. Areas where development or agricultural fields existed were removed from the Ancient Woodlands dataset. The areas delineated in this dataset, represent Ancient Woodlands present as of year-end 2018. Please note: Ancient Woodlands are not the same as "Old Growth Forest".The specific citation for the 1850 and 1890 map are unknown. Harvard Forest georeferenced those maps in ArcGIS software. The 1938 black and white aerial photographs were georeferenced by a consultant hired by Harvard Forest. As an aside FYI, the 1993 photographs (color infrared? black & white?) is the same year of photography which was used for The Nature Conservancy's vegetation delineation of Martha's Vineyard. Not sure if Harvard Forest used the exact same photos as the TNC project but the time period is the same.Harvard Forest is in the process of analyzing the potential ecological benefit of these Ancient Woodlands. Preliminary results show these area have more huckleberry than non-Ancient Woodland areas.The Martha's Vineyard Commission did convert the Harvard Forest Ancient Woodlands data from multi-part polygons to single-part polygons prior to running the Identity analysis.

Level 3 Parcel Data Standard Compliant parcel boundaries for Oak Bluffs, 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.

Parcel data analyzed are: Aquinnah FY24, Chilmark, FY24, Edgartown FY25, Oak Bluffs FY24, Tisbury FY24, and West Tisbury FY23.Visit this website for an explanation of the parcel's assessing info: https://www.mass.gov/info-details/massgis-data-property-tax-parcels#attributes-Through a series of joins, spatial joins and select by location with various datasets, the following key attribute fields were populated in the Municipal Properties dataset.Open Space/Conservation Land Attributes are: OS_ID OS_ID is a unique ID for polygons in the open space/conservation land database, [Fee_Owner], [Level_Protection], OLI_1_INT. For an explanation of the coded values used in these fields, visit: https://www.mass.gov/info-details/massgis-data-protected-and-recreational-openspace#attributes-Zoning info for the parcel is contained within [ZONECODE], [MinLot_ac], and [SubStd_Sz]. Zonecode assigned to a parcel is based on the location of the center point of the parcel. The minimum lot size is per the Town's zoning bylaws. Parcel's smaller than the bylaws minimum lot size were assigned a 'yes' value in the Substandard Size attribute column.The attribute [vacant] was assigned a 'no' value if the assessor's Building Value > $0.00 for the parcel OR the parcel contained one or more structures per the MassGIS structures dataset.The attribute [conserved] was assigned a 'yes' value if the parcel's center point coincided with a parcel in the Dukes County Open Space & Conservation Land dataset.The attribute [AbutPot] Abutter Potential is assigned a 'yes' value if any of the following attributes contain a 'yes' value: [AbutMuni], [AbutOS], or [AbutVacPrv].The attribute [Notes] were manually added by the GIS staff based on local knowledge.Attributes dealing with Abutters: [AbutMuni] indicates if the municipal owned parcel abuts other municipally owned parcels. 'Abuts' are any parcels that thouch (share a boundary) or are within 40ft of each other (this accounts for parcels separated by 'paper streets'). [AbutOS] indicates if the municipal owned parcel abuts a parcel which is open space/conservation land. [AbutVacPrv] indicates if the municipal owned parcel abuts a parcel which is vacant residential land. "Vacant Residential Land" was identified by the assessor's Use Code = 1300 or 1310 for the parcel.Identifying Neighbors: All municipal parcels were buffered 40ft and dissolved together. Then that resulting multi-part dataset was 'exploded' so each distinct polygon was represented by a distinct record in the attribute table. Each polygon was assigned an ID number. This output is the "Municipal Property Clusters".Via a Spatial Join, the respective Cluster (aka group ID) was assigned to the respective municipal parcel. Similarly, by finding the (a) Vacant Residential properties and (b) Conservation Land properties that intersected with the Municipal Property Clusters, the Cluster/Group ID was assigned to the respective vacant residential properties and conservation land properties. A & B each have a distinct dataset which is included in this bundle of data.By having the Group ID in the Municipal Properties dataset and the Vacant Residential and Conservation Land datasets ...let's say a parcel has a Group ID = 3 --> then you can find the abutters by finding the other Municipal Parcels with a Group ID = 3 AND look in the Vacant Residential attribute table for Group ID = 3 AND look in the Conservation Land attribute table for Group ID = 3 --AND then you have tons of info at your fingertips regarding that municipally owned parcel and its abutting vacant properties.

As of June 2021, these are the most current building roofprints for structures in Dukes County, MA. These roofprints were delineated from aerial photos by MassGIS and their subcontractor. The roofprints are not equivalent to footprints. See MassGIS for full methodolgy details. To filter these data by Town_ID: 62 = Chilmark, 89 = Edgartown, 104 = Aquinnah, 109 = Gosnold, 221 = Oak Bluffs, 296 = Tisbury, 327 = West Tisbury.See the full metadata for the roofprint points to learn which year of Assessing data was used for the appended attribute generalizations.Roofprints can represent any structure (i.e. house, guest house, business, barn, shed, garage, etc). The MVC has also provided building centriods (produced from the roofprint polygon). All centroids were forced to be located within the roofprint polygon.The MVC also appended some assessor's data (or deduced some info from the assessor's data) for each roofprint centroid. The respective parcel's LOC_ID, Map_Par_ID, and Poly_Type, was appended to the attribute table based on the parcel that the centroid intersected.The other appended attributes were based on the info in the Assess Table (present within the town's parcel file geodatabase). The assess tables were summarized based on Loc_ID (a unique value for each parcel). If multiple Assess records have the same Loc_ID, the MinYrBlt & MaxYrBlt (Minimum Year Built and Maximum Year Built) across all the assess records for that parcel were appended to all structure points on that parcel. While these data may represent a range of construction dates, it may not encapsulate the full range.Why? ...here we go --> The Assess Table is a record for each owner on a parcel. Hence, a parcel with a condo will have multiple records (having the same LOC_ID) within the Assess Table. However, a parcel with multiple buildings but only one owner, will only have one record in the Assess Table. So, in the latter scenario, which Year Built date goes to which building? - the answer is 'I don't know'. That answer requires more in-depth research with the town Assessor &/or building inspector &/or Registry of Deeds.The following info is based on the 'first' record within the assess table for the respective Loc_ID/parcel.The field of [Status] indicates if a parcel is owned by a Year-round ("YR") or Seasonal ("S") person. This deduction was made based on the owner's mailing address zip code. Off-island zip codes were assigned "S" seasonal and on-Island zip codes were assigned "YR" year-round. The field of [UseType] was deduced from the assessor's use code. "NR" - non residential; "R" - residential.
