Landslide Hazards Legislation in the
116th Congress
Updated December 4, 2020
Authorizing a Landslide Hazards Program
The U.S. Geological Survey (USGS) estimates that landslides kil an average of 25-50 people each year in
the United States and account for $1 bil ion to $2 bil ion annual y in damages. Three nearly identical bil s,
S. 529, H.R. 1261, and H.R. 8810, titled the National Landslide Preparedness Act, would authorize a
national landslide hazards reduction program within the USGS. The USGS currently operates, under its
Organic Act of 1879 and other authorities, such as the Disaster Relief Act of 1974 (P.L. 93-288), a
Landslide Hazards Program (funding level of $4.0 mil ion in FY2020) within its Natural Hazards
Program. The bil s would broaden the USGS’s current activities and require coordination with other
federal agencies.
The legislation would direct the Secretary of the Interior (Secretary), acting through the Director of the
USGS, to establish a program to identify risks and hazards from landslides, reduce losses, protect
communities at risk, and improve communication and emergency preparedness. The bil s would require
the program to map and assess landslide hazards; respond to landslide events; coordinate with nonfederal
entities to identify regional and local priorities; and develop and implement landslide hazard guidelines
for geologists, engineers, emergency managers, and land-use decisionmakers.
The House passed H.R. 1261 on June 3, 2019, the Senate passed S. 529 on July 30, 2020, and the House
passed H.R. 8810 on December 3, 2020. Congress must reconcile differences in the bil s (e.g., reporting,
authorization of appropriations, and technical terminology) to enact the legislation.
Managing the Program
Section 3 of the bil s would structure the program with elements roughly paral el to the National
Earthquake Hazards Reduction Program (NEHRP; P.L. 115-307). An interagency committee chaired by
the Department of the Interior (DOI) would oversee and coordinate the landslide program and support the
development and execution of a national strategy for landslide hazards and risk reduction. The national
strategy would include an interagency plan for carrying out the national strategy.

Advisory Committee
The bil s would establish an advisory committee on landslides that would provide advice and
recommendations to the interagency committee on implementing the program. It would include members
from states, territories, Indian tribes, research and academic institutions, industry standards development
organizations, and emergency management agencies.
Data, Early Warning, and Emergency Response
The program would develop a publicly accessible national landslide hazards database. It also would
develop planning and risk-reduction guidance, maps, tools, and training materials for nonfederal
governments and decisionmakers to assist their efforts in reducing landslide risks. The legislation would
direct the Secretary, in coordination with the Secretaries of Commerce and of Homeland Security, to
expand the early warning system for flash floods and debris flows, particularly for increased risk
following wildfires. In addition, the bil s cal for the program to establish emergency response procedures
for rapid deployment of federal assets to areas affected by a landslide event.
Cooperative Grants
Section 3 of the bil s would authorize landslide-related grant programs. DOI, acting through the USGS,
would administer a cooperative grant program, available to nonfederal governments for landslide
research, mapping, assessment, and data collection. The cooperative grant program would prioritize
projects that would achieve the greatest hazard risk reduction, reflect goals of the national strategy, and
have a minimum 50% nonfederal cost share. The National Science Foundation would administer a
separate research grant program to fund studies reflecting the goals and priorities of the national strategy.
3D Elevation Program
The bil s would authorize—in Section 5—a three-dimensional (3D) elevation program that could be
viewed as complementary to, and providing data that would be important for, the landslide hazards
program authorized in Section 3. The bil s define 3D elevation data as “3D, high-resolution data obtained
using LiDAR, IfSAR, or other methods over the United States.” Section 5 would authorize what is
currently an initiative at the USGS. High-quality, precise, and accurate elevation data general y are
considered important to better understand landslide hazards, flood hazards, and changes to the Earth’s
land surface, such as land subsidence from groundwater pumping.
Both bil s would establish a program with three broad goals:
1. Provide 3D elevation data coverage for the United States;
2. Coordinate and facilitate the collection, dissemination, and use of 3D elevation data
among federal agencies and nonfederal entities; and
3. Produce standard, publicly accessible 3D elevation products.
To achieve these goals, the legislation would enable the use of cooperative agreements and promote the
development and maintenance of spatial data infrastructure; the development of standards and guidelines;
and the identification, assessment, and adoption of emerging technology.

Managing and Advising the Program
Similar to the landslide program and NEHRP, the legislation would authorize an interagency coordinating
committee, chaired by the Secretary. The coordinating committee also would develop a strategic plan and
a management plan to implement the strategic plan.
Section 5 would create a subcommittee of the National Geospatial Advisory Committee, an entity
authorized under the National Geospatial Data Act of 2018 (P.L. 115-307), to advise the 3D elevation
program interagency coordinating committee. The advisory committee would assess trends in 3D data
collection and in science and technology, and it would assess effectiveness; the need to revise; and
management, implementation, and activities of the 3D elevation program.
Grants and Cooperative Agreements
The 3D elevation program would be authorized to make grants and enter into cooperative agreements
with other federal agencies, as wel as with nonfederal governments; institutions of higher education;
nonprofit research organizations; and other organizations. The objective would be to improve nationwide
coverage of 3D elevation data, and the agreements would require making data publicly available and
interoperable with other federal datasets, as determined by the Secretary of the Interior.
For the Landslide Hazards Program, H.R. 1261 would authorize $37 mil ion annual y from FY2020 to
FY2023, whereas S. 529 and H.R. 8810 would authorize $37 mil ion annual y from FY2021 to FY2024.
For the 3D elevation program, H.R. 1261 would authorize $40 mil ion annual y from FY2020 to FY2023,
S. 529 would authorize $20 mil ion annual y from FY2021 to FY2024, and H.R. 8810 would authorize
$40 mil ion annual y from FY2021 to FY2024.
