a result of burning coal. 
(b) CAPITOL POWER PLANT DEFINED.—In this sec-
tion, the term ‘‘Capitol power plant’’ means the power 
plant constructed in the vicinity of the Capitol Complex 
in the District of Columbia pursuant to the Act of April

PART 1—WATER RESOURCES 
SEC. 8701. POLICY OF THE UNITED STATES. 
It is the policy of the United States that all Federal 
water resources projects— 
(1) reflect national priorities for flood damage 
reduction, navigation, ecosystem restoration, and 
hazard mitigation and consider the future impacts of 
increased hurricanes, droughts, and other climate 
change-related weather events; 
(2) avoid the unwise use of floodplains, mini-
mize vulnerabilities in any case in which a floodplain 
must be used, protect and restore the extent and 
functions of natural systems, and mitigate any un-
avoidable damage to aquatic natural system; and

(3) to the maximum extent possible, avoid im-
pacts to wetlands, which create natural buffers, help 
filter water, serve as recharge areas for aquifers, re-
duce floods and erosion, and provide valuable plant 
and animal habitat. 
SEC. 8702. 21ST CENTURY WATER COMMISSION. 
(a) ESTABLISHMENT.—There is established a com-
mission to be known as the 21st Century Water Commis-
sion (in this section referred to as the ‘‘Commission’’). 
(b) DUTIES.—The duties of the Commission shall be 
to— 
(1) use existing water assessments and conduct 
such additional studies and assessments as may be 
necessary to project— 
(A) future water supply and demand; 
(B) impacts of climate change to our Na-
tion’s flood risk and water availability; and 
(C) associated impacts of climate change 
on water quality; 
(2)(A) study current water management pro-
grams of Federal, interstate, State, and local agen-
cies and private sector entities directed at increasing 
water supplies and improving the availability, reli-
ability, and quality of freshwater resources; and

(B) evaluate such programs’ hazard mitigation 
strategies and contingency planning in light of cli-
mate change impacts, including sea level rise, flood-
ing, and droughts; and 
(3) consult with representatives of such agen-
cies and entities to develop recommendations, con-
sistent with laws, treaties, decrees, and interstate 
compacts, for a comprehensive water strategy to— 
(A) recognize the primary role of States in 
adjudicating, administering, and regulating 
water rights and water uses; 
(B) identify incentives intended to ensure 
an adequate and dependable supply of water to 
meet the needs of the United States for the 
next 50 years, including the future impacts of 
climate change on water supply and quality; 
(C) eliminate duplication and conflict 
among Federal governmental programs; 
(D) consider all available technologies (in-
cluding climate change predictions, advanced 
modeling and mapping of wetlands, floodplains, 
and other critical areas) and other methods to 
optimize water supply reliability, availability, 
and quality, while safeguarding and enhancing 
the environment and planning for the potential

impacts of climate change on water quality, 
water supply, flood and storm damage reduc-
tion, and ecosystem health; 
(E) recommend means of capturing excess 
water and flood water for conservation and use 
in the event of a drought; 
(F) identify adaptation techniques, or fur-
ther research needs of adaptation techniques, 
for effectively conserving freshwater and coastal 
systems as they respond to climate change; 
(G) suggest financing options, incentives, 
and strategies for development of comprehen-
sive water management plans, holistically de-
signed water resources projects, conservation of 
existing water resources infrastructure (except 
drinking water infrastructure) and to increase 
the use of nonstructural elements (including 
green infrastructure and low impact develop-
ment techniques); 
(H) suggest strategies for avoiding in-
creased mandates on State and local govern-
ments; 
(I) suggest strategies for using best avail-
able climate science in projections of future 
flood and drought risk, and for developing haz-

ard mitigation strategies to protect water qual-
ity, in extreme weather conditions caused by cli-
mate change; 
(J) identify policies that encourage low im-
pact development, especially in areas near high 
priority aquatic systems; 
(K) suggest strategies for encouraging the 
use of, and reducing biases against, non-
structural elements (including green infrastruc-
ture and low impact development techniques) 
when managing stormwater, including features 
that— 
(i) preserve and restore natural proc-
esses, landforms (such as floodplains), nat-
ural vegetated stream side buffers, wet-
lands, or other topographical features that 
can slow, filter, and naturally store 
stormwater runoff and flood waters for fu-
ture water supply and recharge of natural 
aquifers; 
(ii) utilize natural design techniques 
that infiltrate, filter, store, evaporate, and 
detain water close to its source; or
