<DIV STYLE="text-align:Left;"><DIV><P><SPAN>The Nebraska Structure Inventory layer provides point data for almost 929,781 buildings across Nebraska. The data is sourced from the National Structure Inventory, created by USACE in 2022. Data was collected mainly from Lightbox parcel files for residential structures and ESRI business layer for non-residential structures. Additional data is collected from HAZUS, USACE, Homeland Infrastructure Foundation-Level Data, ESRI, Microsoft, FEMA, U.S. Census Bureau, NCES, and U.S. Geological Survey. Full technical documentation for the National Structure Inventory is available at: https://www.hec.usace.army.mil/confluence/nsi/technicalreferences/2022/technical-documentation.The layer serves as a valuable for identifying the location and information about buildings across Nebraska, for use in projects like the Nebraska Real-time Flood Forecasting (NeRFF) Site. Relevant information for each building is provided, including occupancy type, number of stories, structure and foundation types, flood zone, ground elevation, foundation height, census block, population, and value estimates.</SPAN></P></DIV></DIV>
The Nebraska Structure Inventory layer provides point data for almost 930,000 buildings across Nebraska in 2022.

USACE performed Structure Placement Refinement testing to determine the location of each structure. The XY location for each structure was provided by the source data, which was matched with building footprints and parcel polygons to refine the location. Overlapping and stacked points were matched to the best designated footprint or aggregated together (Ex: RES3F is a multi-family housing with 50+ units).

USACE compiled population estimates using 2010 block data and 2020 county data along with a NSI Generator to estimate the population at each building. Depreciated replacement values were estimated using an assumed replacement category and dollar per square footage estimate for the category. Square footage, number of stories, and foundation height were gathered from parcel data. Ground elevations were determined using the USGS National Elevation Dataset based on structure location

USACE gathered occupancy types based on FEMA occupancy type definitions and USACE economic guidance memorandums. Construction type is mapped from parcel data and HAZUS data.

The attribute table information was updated. Acronyms were replaced with their full description for the following fields: st_damcat, occtype, bldgtype, source, ftprntsrc, and found_type.
This was completed to increase ease of access for public use of the data.
