(B) Manufactured home standards. Require all manufactured homes to be installed using methods and practices which minimize flood damages. Manufactured homes must be elevated and anchored to resist flotation, collapse or lateral movement.
(C) Utility construction.
(1) Require new and replacement water and sewer systems to be designed to minimize infiltration.
(2) Require on-site waste disposal systems to be designed to avoid impairment.
(D) Record keeping.
(1) Obtain and maintain records of elevation and flood proofing levels for new construction or substantial improvements.

(d) Electrical, heating, ventilation, plumbing, air-conditioning equipment and other service facilities to be designed or located to prevent entry or accumulation of water;
(e) Fully enclosed areas below the lowest floor of an elevated building (if permitted by local ordinances) to be designed to automatically equalize hydrostatic flood forces by allowing for the entry and exit of flood waters.
