(ii)
Eligible activities.—
(I)
In general.—
An eligible entity may use a resilience improvement grant under this subparagraph for 1 or more construction activities to improve the ability of an existing surface transportation asset to withstand 1 or more elements of a weather event or natural disaster, or to increase the resilience of surface transportation infrastructure from the impacts of changing conditions, such as sea level rise, flooding, wildfires, extreme weather events, and other natural disasters.
(II)
Inclusions.—
An activity eligible to be carried out under this subparagraph includes—
(aa)
resurfacing, restoration, rehabilitation, reconstruction, replacement, improvement, or realignment of an existing surface transportation facility eligible for assistance under this title;
(bb)
the incorporation of natural infrastructure;
(cc)
the upgrade of an existing surface transportation facility to meet or exceed a design standard adopted by the Federal Highway Administration;
(dd)
the installation of mitigation measures that prevent the intrusion of floodwaters into surface transportation systems;
(ee)
strengthening systems that remove rainwater from surface transportation facilities;
(ff)
upgrades to and installation of structural stormwater controls;
(gg)
a resilience project that addresses identified vulnerabilities described in the resilience improvement plan of the eligible entity, if applicable;
(hh)
relocating roadways in a base floodplain to higher ground above projected flood elevation levels, or away from slide prone areas;
(ii)
stabilizing slide areas or slopes;
(jj)
installing riprap;
(kk)
lengthening or raising bridges to increase waterway openings, including to respond to extreme weather;
(ll)
increasing the size or number of drainage structures;
(mm)
installing seismic retrofits on bridges;
(nn)
adding scour protection at bridges;
(oo)
adding scour, stream stability, coastal, and other hydraulic countermeasures, including spur dikes;
(pp)
vegetation management practices in transportation rights-of-way to improve roadway safety, prevent against invasive species, facilitate wildfire control, and provide erosion control; and
(qq)
any other protective features, including natural infrastructure, as determined by the Secretary.
(iii)
Priority.—
The Secretary shall prioritize a resilience improvement grant to an eligible entity if—
(I)
the Secretary determines—
(aa)
the benefits of the eligible activity proposed to be carried out by the eligible entity exceed the costs of the activity; and
(bb)
there is a need to address the vulnerabilities of surface transportation assets of the eligible entity with a high risk of, and impacts associated with, failure due to the impacts of weather events, natural disasters, or changing conditions, such as sea level rise, wildfires, and increased flood risk; or
(II)
the eligible activity proposed to be carried out by the eligible entity is included in the applicable resilience improvement plan under subsection (e)(2).
