Layer: HistoricStructures_TotalExposure (0)


Name: HistoricStructures_TotalExposure

Display Field: TOWN_NAME

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description:

In MACRIS the points are symbolized to indicate the most common historic designation types: 1) National Register of Historic Places, 2) local historic district, 3) both National Register and local historic district, 4) Preservation Restriction, and 5) inventoried but not designated with one of the previous designations. Less common designations are not symbolized in MACRIS, but are included in the Designations attribute field. MassGIS stores a copy of the point feature class as MHCINV_PT. MassGIS projected the data to the NAD1983 Mass. State Plane Meters Mainland coordinate system.

Layer: Nantucket_HURR_INUN_ZONES_POLY:Nantucket_HURR_INUN_ZONES_POLY (1)


Name: Nantucket_HURR_INUN_ZONES_POLY:Nantucket_HURR_INUN_ZONES_POLY

Display Field: HURR_CAT

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

This layer represents worst-case Hurricane Surge Inundation areas for Category 1 through 4 hurricanes striking the coast of Massachusetts. Hurricane surge values were developed by the National Hurricane Center using the PV2 basin SLOSH (Sea Lake and Overland Surge from Hurricanes) Model data. This Surge Inundation layer was created by the U.S. Army Corps of Engineers, New England District. Using ArcInfo's Grid extension, LiDAR bare earth elevation data were subtracted from the worst-case hurricane surge values to determine which areas could be expected to be inundated. The layer is named HURR_INUN_ZONES_POLY.
