This web map was compiled by the Martha's Vineyard Commission (MVC) for planning purposes only. The flood data is provided by FEMA (effective 2016) and uploaded to ArcGIS Online by the MVC. Click here for more details about FEMA Flood Zones. For an official determination of whether or not a specific location is located within a Flood Hazard Ares, please visit FEMA's Map Service Center. This web map/App is provided for planning purposes only. The map also includes parcel boundaries and building outlines (the latter generated from roof outlines visible on aerial photos). The parcel data is assembled and published to ArcGIS OnLine by MassGIS. The online hosted data were last updated by MassGIS in May 2021. The parcel pop-up information is from a data extract from the respective town's assessing database. These data were current on date of extraction and may not reflect the most current assessing info. For the most current assessing info, please contact the Town's Assessing Office. The parcel boundaries and attribute table conform to the State's Level 3 Parcel Data Standard. See MassGIS for full details. The building outlines (roofprints) were created and then published as a tile layer (no site specific info available) by MassGIS.
