The 2015 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The records in this file allow users to map the parts of Urban Areas that overlap a particular county. After each decennial census, the Census Bureau delineates urban areas that represent densely developed territory, encompassing residential, commercial, and other nonresidential urban land uses. In general, this territory consists of areas of high population density and urban land use resulting in a representation of the "urban footprint." There are two types of urban areas: urbanized areas (UAs) that contain 50,000 or more people and urban clusters (UCs) that contain at least 2,500 people, but fewer than 50,000 people (except in the U.S. Virgin Islands and Guam which each contain urban clusters with populations greater than 50,000). Each urban area is identified by a 5-character numeric census code that may contain leading zeroes. The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities. The boundaries for counties and equivalent entities are as of January 1, 2010.

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.

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.

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.

I. SNEP HRU Project Background The Southeast New England Program (SNEP) region consists of watersheds in Massachusetts and Rhode Island that primarily drain into Narragansett Bay, Buzzards Bay, or Nantucket Sound. It encompasses all or portions of 134 municipalities many of which are highly developed. The region faces multiple water quality issues with stormwater being previously identified a major contributor. These maps have been generated for all 134 Municipalities including 81 subwatersheds in the SNEP region to provide organizations and municipalities a way to understand where significant stormwater pollution may be originating. For organizations or municipalities with GIS capabilities the data that created these maps is available as well. II. What are HRUs? Hydrologic Response Units (HRUs) describe a landscape through unique combinations of land use and land cover (residential, commercial, forest, etc.), soil types (A, B, C, D), and additional characteristics such as slope, and impervious cover. These landscape characteristics, or HRUs, provide the building block to quantify stormwater pollutant loads (nitrogen, phosphorus, and total suspended solids (TSS)) originating from a given land area. The HRUs and nutrient pollutant loads in stormwater provides a baseline from which reduction targets can be created. III. How can HRUs be used? These maps and their underlying data can provide critical information to municipalities, watershed organizations, EPA, and others to assess stormwater pollutant loads in SNEP watersheds. EPA expects that this information will facilitate further understanding of the distribution of stormwater pollutant load source areas throughout the watersheds. This information serves to advance a broader understanding of stormwater impacts and potential management options by the public and direct stakeholders. Consistent HRUs may help municipalities implement MS4 permitting requirements and facilitate stormwater management strategies, such as land use conversion, stormwater Control Measure (SCM) siting, and targeting areas for conservation. HRU mapping can identify best locations for SCMs and can be utilized with additional stormwater planning tools (such as EPA’s Opti-Tool) to develop a cost-effective stormwater management plan. By providing a consistent HRU map for the SNEP region, practitioners can focus their efforts on implementation of SCM strategies rather than mapping their landscape. Hotspot mapping is a tool that integrates the HRU analysis and stormwater runoff pollutant load outputs to indicate areas where pollutant loads are highest and areas that stormwater controls may be best implemented. The HRUs and pollutant loads can be overlayed with parcel analysis to determine which parcels have high loads/areas of large impervious cover. The parcel data can help towns prioritize their efforts by determining the properties with highest potential to reduce pollutant loads through stormwater controls. Similarly, it can help determine which properties have large stormwater pollutant loads. IV. Other Resources HRUs That have been completed by EPA - Taunton River Watershed FDC Project and Tisbury, MA IC Disconnection Project The Cape Cod Commission developed HRUs for Barnstable County (CCC: Barnstable County HRUs). The UNH Stormwater Center developed parcel level hotspot mapping in New Hampshire for municipalities to prioritize where new BMPs should be placed (UNHSC: NH Hotspot Mapping).

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.

This polygon feature class contains the land, pond, and offshore areas within Dukes County MA. These data are intended for cartographic display and not survey-grade, legal definition.This dataset was compiled from several other datasets published by MassGIS. The coastline and inland ponds are believed to be at 1:25,000 scale based on wetlands data from the early 2000. The 3-mile extent is from an offshore 1:80,000 scale feature class. The town boundaries (on land) are from the Community Boundaries dataset of 2002. The town bounds across ponds were created by the MVC based on USGS topo maps.All data processing was done in ArcPro using primarily Identity geoprocessing tool to merge the various datasets together & to distinguish land, ponds, and off-shore. The attribute [type] was added to indicate a polygon as land, pond, or offshore.The two key files used from the MVC's data inventory were [town_detailed_duk_noh2o] and [interior_town_arcs6].Note: There are many town boundary datasets available and discrepancies in the town bounds among those datasets are numerous. This dataset of extents, does not claim to be the 'official' record of town bounds. If you need 'official', survey-grade data, please look elsewhere.

Created by the Martha's Vineyard Commission after reviewing local zoning bylaws, speaking with town historic district committees, and reviewing State & National Registry of historic districts. Area boundaries are parcel based where zoning descriptions permitted clear property boundaries.
