HAZUS

Bndrygbs.mdb

hzCensusBlock

Provides the structure building schemes and block type.

flSchemeCoastal, flSchemeRiverine, flSchemeGLakes

Provides information on foundation type and height.

MSH.mdb

flGenBldgScheme

Provides the construction type distributions and NFIP entry year for structures.

USACE

NSI 2015

Base layer

Used in any Census Block that lacks ESRI or CoreLogic data.

Homeland Infrastructure Foundation-Level Data

Lightbox

County Level Data

Parcel polygons and associated data tables; used for initial spatial location and occupancy type, and may influence structure attributes (square feet, foundation type, etc) of single-family structures.

Nursing Home

Point data indicating the presence of a nursing home and its number of beds.

Hospital

Point data indicating the presence of a hospital and its number of beds.

Mobile Home

Point data indicating the presence of a mobile home park and the number of units associated with the park (either exact units, or a range).
