16 (m) SENSE OF CONGRESS.—It is the sense of Con17 gress that, because the pilot program is limited with re18 spect to scope and resources, communities that participate 

19 in the pilot program should acknowledge that the most 

20 successful efforts to mitigate the effects of urban flood21 ing— 

22 (1) take a structural-based mitigation approach 

23 with respect to construction, which includes— 

24 (A) recognizing any post-storm damage 

25 that may occur; and 


ssavage on LAPJG3WLY3PROD with BILLS
14 

•S 5386 IS

1 (B) pursuing designs that proactively mini2 mize future flood damage; 

3 (2) make individuals in the community aware, 

4 through any cost-effective and available means of 

5 education, of the best approaches regarding the con6 struction of properties that are able to survive 

7 floods, which reduces the cost of future repairs; and 

8 (3) encourage home and property owners to 

9 consider the measures described in paragraphs (1) 

10 and (2), which are the most cost-effective and pru11 dent ways to reduce the impact of flooding, when 

12 constructing or renovating building components. 

13 (n) FUNDING.—There are authorized to be appro14 priated for grants under the pilot program— 

15 (1) $1,200,000 for fiscal year 2026; and 

16 (2) $4,300,000 for fiscal year 2027, to remain 

17 available through fiscal year 2029.
