USGS and FEMA collaborated to collect data on residences in six of the twenty disaster-declared parishes in Louisiana during the August 8–11 floods in 2016. The National Map Corps (TNMCorps), a volunteer program run the National Geospatial Program of the U.S. Geological Survey, were invited to help with this task. From August 30 to September 30, 2016, Corps editors created and classified data points for each building within the six parishes. FEMA used this information to find which buildings in the parishes were residences, and to estimate by how many feet underwater the houses were. This data was then used to help determine the amount of assistance provided to homeowners in these parishes.The data points were summarized into 5 km hexagons (a process called hexbinning) to provide an easier visualization of the number of points collected by TNMCorps. Lighter colors indicate more buildings per hexagon. Per-hexagon numbers range from 1 to 1800.Map also includes flood extent estimates from FEMA and GOSEP (Louisiana Governer's Office of Homeland Security & Emergency Management). Parish outlines derived from U.S. Census TIGER data.

The latest geometric revision to the Parish Boundaries was made 8/2/2012.All revisions are described below under "Credits".Louisiana Parish Boundaries approved by Resolution of the GIS Council on January 19, 2000. This is a region dataset depicting the polygon boundaries of the 64 parishes comprising the state of Louisiana. Parish boundaries extend 3 miles out into the Gulf of Mexico from the coastline. This dataset was derived from many data sources and conveys the best currently (2005) available representation of the parishes of Louisiana and as a consequence, the best currently available representation of the territorial bounds of the state.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

Heavy rainfall occurred across Louisiana during March 8-19, 2016, as a result of a massive, slow-moving southward dip in the jet stream, which moved eastward across Mexico, then neared the Gulf Coast, funneling deep tropical moisture into parts of the Gulf States and the Mississippi River Valley. The storm caused major flooding in north-central and southeastern Louisiana. Digital flood-inundation maps for a 32.4-mile reach within the community of Covington near the Tchefuncte River in Washington Parish and Tangipahoa Parish, LA was created by the U.S. Geological Survey (USGS) in cooperation with Federal Emergency Management Agency (FEMA) to support response and recovery operations following a March 8-19, 2016 flood event. The inundation maps depict estimates of the areal extent and depth of flooding corresponding to 24 high-water marks (HWM) identified and surveyed by the USGS following the flood event.
