; (2) how the activities carried out with such grant amounts have met the objectives described in subsection (b); and (3) any lessons learned in carrying out such activities and any recommendations for future mapping modernization efforts by the Federal Emergency Management Agency. (k) Biennial reports by FEMA Not later than the expiration of the 24-month period beginning on the date of the enactment of this Act, and not later than the expiration of each successive 24-month period thereafter until the completion of all activities carried out with amounts from grants under the pilot program under this section, the Administrator shall submit to the Congress and make available to the public on an Internet website a report that— (1) describes— (A) the progress of the activities carried out with amounts from such grants; and (B) the effectiveness of technology-based mapping tools used in carrying out the activities described in subparagraph (A); and (2) with respect to the final report that the Administrator is required to submit under this subsection, includes recommendations to the Congress and the executive branch of the Federal Government for implementing strategies, practices, and technologies to mitigate the effects of urban flooding. (l) Sense of Congress It is the sense of Congress that, because the pilot program is limited with respect to scope and resources, communities that participate in the pilot program should acknowledge that the most successful efforts to mitigate the effects of urban flooding— (1) take a structural-based mitigation approach with respect to construction, which includes— (A) recognizing any post-storm damage that may occur; and (B) pursuing designs that proactively minimize future flood damage; (2) make individuals in the community aware, through any cost-effective and available means of education, of the best approaches regarding the construction of properties that are able to survive floods, which reduces the cost of future repairs
