(1)
General review and evaluation— In conducting the study, the National Academy of Sciences shall review and evaluate the latest available research, laws, regulations, policies, best practices, procedures, and institutional knowledge regarding urban flooding.
(2)
Specific issue areas— The study shall include, at a minimum, an examination of the following:
(A)
The prevalence and costs associated with urban flooding events across the United States, with a focus on the largest metropolitan areas and any clear trends in frequency and severity over the past 2 decades.
(B)
The adequacy of existing federally provided flood risk information and the most cost effective methods and products to identify, map, or otherwise characterize the risk of property damage from urban flooding on a property-by-property basis, whether or not a property is in or adjacent to a 1-percent (100-year) flood plain, and the potential for training and certifying local experts in flood risk characterization as a service to property purchasers and owners and their communities.
(C)
The causes of urban flooding and its apparent increase over the past 20 years, including the impacts of—
(i)
global climate change;
(ii)
increasing urbanization and the associated increase in impervious surfaces; and
(iii)
undersized, deteriorating, and otherwise ineffective stormwater infrastructure.
(D)
The most cost-effective strategies, practices, technologies, policies, standards, or rules used to reduce the impacts of urban flooding, with a focus on decentralized, easy-to-install, and low-cost approaches, such as nonstructural and natural infrastructure on public and private property. The examination under this subparagraph shall include an assessment of opportunities for implementing innovative strategies and practices on government-controlled land, such as Federal, State, and local roads, parking lots, alleys, sidewalks, buildings, recreational areas, and open space.
(E)
The role of the Federal Government and State governments, as conveners, funders, and advocates, in spurring market innovations based on public-private-nonprofit partnerships. Such innovations may include smart home technologies for improved flood warning systems connected to high-resolution weather forecast data and Internet- and cellular-based communications systems.
(F)
The most sustainable and effective methods for funding flood risk and flood damage reduction at all levels of government, including—
(i)
the potential for establishing a State revolving fund program for flood prevention projects similar to the revolving fund programs under the Federal Water Pollution Control Act and the Safe Drinking Water Act;
(ii)
stormwater fee programs using impervious surface as the basis for fee rates and providing credits for the installation of flood prevention or other stormwater management features;
(iii)
grant programs; and
(iv)
public-private partnerships.
(G)
Information and education strategies and practices, including nontraditional approaches such as the use of community colleges and social media, for community leaders, government staff, and property owners on—
(ii)
flood risk reduction strategies and practices; and
(iii)
the availability and effectiveness of different types of flood insurance policies.
(H)
The relevance of the National Flood Insurance Program and Community Rating System to urban flooding areas outside traditional flood plains, and strategies for improving compliance, broadening coverage, and increasing participation under the programs.
(I)
Strategies for protecting communities in the lower elevations of a watershed or drainage area from the flooding impacts of development in upstream communities, including a review of—
(i)
potential standards for watershed-wide flood protection planning; and
(ii)
cost-effective and equitable legal options for a downstream community when upstream communities act in a way that increases flooding downstream.
(J)
Cost-effective strategies for reducing infiltration/inflow into combined and separate sewer systems.
(K)
Opportunities to increase coordination between stormwater management programming under the Federal Water Pollution Control Act (
33 U.S.C. 1251 et seq.) and flood risk management and mitigation programming under various laws, including the Robert T. Stafford Disaster Relief and Emergency Assistance Act (
42 U.S.C. 5121 et seq.) and the National Flood Insurance Act of 1968 (
42 U.S.C. 4001 et seq.).
