K. The permit agent shall require, within floodplains, new and replacement water supply systems to be designed to minimize or eliminate infiltration of floodwaters into the systems.
L. The permit agent shall require, within floodplains:

N. The permit agent shall obtain, review, and reasonably utilize any base flood elevation data available from a federal, state, or other source, until such other data has been provided by the FEMA, as criteria for requiring that:
1. Development and substantial improvements of nonresidential structures have the lowest floor (including basement) elevated to or above the 100-year flood level; and

2. Require the applicant to furnish, if the structure has been floodproofed, the elevation data (in relation to mean sea level) to which the structure was floodproofed; and
3. Maintain a record of all such information for public inspection at the city or town clerk-treasurer's office.
P. The permit agent shall notify, in river or stream flooding situations, adjacent communities and the Oklahoma water resources board prior to any alteration or relocation of a watercourse, and submit copies of such notification to the administrator.
Q. The permit agent shall assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained.
R. The permit agent shall require that manufactured homes placed within zone A on the community's flood hazard boundary map shall be anchored to resist flotation, collapse, or lateral movement by providing over the top and frame ties to ground anchors. Specific requirements shall be that:
1. Over the top ties be provided at each of the four (4) corners of the manufactured home, with two (2) additional ties per side;
2. Frame ties be provided at each corner of the home with five (5) additional ties per side at intermediate points, manufactured homes less than fifty feet (50') long requiring only four (4) additional ties per side;
3. All components of the anchoring system be capable of carrying a force of four thousand eight hundred (4,800) pounds; and
4. Any additions to the manufactured home be similarly anchored.
5. The permit agent shall require an evacuation plan indicating alternative vehicular access and exit routes be filed with local civil defense director for manufactured home parks and manufactured home subdivisions located within zone A of community FHBM as delineated by FEMA.
