Upon consideration of the factors listed above and the purposes of this Section, the Planning Commission may attach such conditions to the granting of a special use permit as it deems necessary to further the purposes of flood plain protection.
(a) Modification of waste disposal and water supply facilities.
(b) Limitations on periods of use and operation.
(c) Imposition of operational controls, sureties and deed restrictions.
(d) Requirements for construction of channel modification, dikes, levees and other protective measures.
(e) Floodproofing measures. Floodproofing measures such as the following shall be designed consistent with the regional flood protection elevation for the particular area, flood velocities, durations, rate of rise, hydrostatic and hydrodynamic forces, and other factors associated with the regional flood. The Planning Commission shall require that the applicant submit a plan or document certified by a registered professional engineer that the floodproofing measures are consistent with the regional flood protection elevation and associated flood factors for the particular area. The following floodproofing measures may be required without limitation because of specific enumeration:
(1) Anchorage to resist flotation and lateral movement.
(2) Installation of watertight doors, bulkheads, and shutters, or similar methods of construction.
(3) Reinforcement of walls to resist water pressures.
(4) Use of paints, membranes, or mortars to reduce seepage of water through wells.
(5) Addition of mass or weight to structure to resist flotation.
(6) Installation of pumps to lower water levels in structures.
(7) Construction of water supply and waste treatment systems so as to prevent the entrance of floodwaters.
(8) Pumping facilities or comparable practices for subsurface drainage systems for buildings to relieve external foundation wall and basement flood pressures.
(9) Construction to resist rupture or collapse caused by water pressure or floating debris.
(10) Installation of valves or controls on sanitary and storm drains which will permit the drains to be closed to prevent backup of sewage and storm water into the buildings or structures. Gravity drainage of basements may be eliminated by mechanical devices.
(11) Location of any structural storage facilities for chemicals, explosives, buoyant materials, flammable liquids or other toxic materials which could be hazardous to public health, safety, and welfare in a matter which will assure that the facilities are situated at elevations above the height associated with the regional flood protection elevation.
