Project Priorities .—

In selecting projects to be carried out under this section, the Secretary concerned shall give a priority to a project proposal that—
(1)
minimizes the runoff of untreated stormwater into freshwater systems or tidal systems;
(2)
protects military installations and defense access roads from stormwater runoff and water levels resulting from extreme weather conditions;
(3)
controls shoreline erosion control that involve the improvement, protection, or repair of shoreline subject to wave action or stormwater runoff and water levels resulting from extreme weather condition; or
(4)
supports water resilience at military installations.
(d)

Project Activities .—

Activities carried out as part of a project under this section may include, but are not limited to, the following:
(1)
The installation, expansion, or refurbishment of stormwater ponds and other water-slowing, retention, or filtration measures to address storm water management.
(2)
The installation of permeable pavement in lieu of, or to replace existing, nonpermeable pavement.
(3)
The use of planters, tree boxes, cisterns, and rain gardens to reduce stormwater runoff.
(4)
The capture or storage of stormwater for use in supporting water resilience at a military installation.
(5)
The use of sheet piles, riprap, armor stone, sea walls, natural plantings, or any other technologies created to address shoreline erosion control.
(e)

Project Coordination .—

(1)
In the case of a project carried out under this section on or related to a military installation and any project related to the same installation carried out under section 2391, 2684, 2815, or 2914 of this title, the Secretary concerned shall ensure coordination between the projects regarding the water access, management, conservation, security, and resilience aspects of the projects.

The Assistant Secretary of Defense for Energy, Installations, and Environment shall designate an official to be responsible for coordinating projects under this section among the military departments.
(f)

Annual Report .—

(1)
Not later than 90 days after the end of each fiscal year, each Secretary concerned shall submit to the congressional defense committees a report describing—
(A)
the status of planned and active projects carried out by that Secretary under this section; and
(B)
all projects completed by the Secretary concerned during the previous fiscal year.
(2)
Each report shall include the following information with respect to each project described in the report:
(A)
The title, location, a brief description of the scope of work, the original project cost estimate, and the current working cost estimate.
(B)
The rationale for how the project will—
(i)
improve military installation resilience or the resilience of a defense access road or other essential civilian infrastructure supporting a military installation;
(ii)
protect waterways and stormwater-stressed ecosystems;
(iii)
improve, protect, or repair shoreline to protect infrastructure of a military installation or a defense access road from shoreline erosion; or
(iv)
provide water storage and filtration, flood mitigation, or otherwise support water resilience.
(C)
Such other information as the Secretary concerned considers appropriate.
(g)
