(A) Site planning. Design and construction of all subdivisions and uses for which a Class II permit is required shall minimize flood damage. Utilities and structures shall be located and designed to minimize flood damage, and the site shall be graded and drained to guide flood water around and away from existing and/or proposed buildings.
(B) Residential development. All residential buildings shall comply with the International Residential Building Code.
(1) Where base flood elevation data is not available through the flood insurance study or from another source, applications shall be reviewed to assure that the proposed construction will be reasonably safe from flooding. This determination of reasonableness shall be based on evidence submitted with the application by the developer, including historical flood records, photographs of past flood events, and similar documentation. The minimum elevation above grade in such cases shall be two feet.
(2) Recreational vehicles placed on sites are required to either: be on the site for fewer than 180 consecutive days; or be fully licensed and ready for highway use, on its wheels or jacking system, is attached to the site only by quick disconnect type utilities and security devices, and has no permanently attached additions.
(C) Nonresidential development. All nonresidential buildings shall comply with the International Building Code.
(D) Floodway. The floodway is the channel of a watercourse and any adjacent land area that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. The FLOODWAY is a hazardous area due to the velocity of flood waters which carry debris and potential projectiles and the high erosion potential. Encroachments into the floodway, including fill, new construction, substantial improvements, and other development, shall be prohibited unless an engineer or architect certifies that the encroachment will not result in any increase in the flood level during the base flood discharge.
(E) Maintenance of flood capacity. Continuing maintenance to prevent the reduction of flood carrying capacity in altered or relocated watercourses shall be required.
(F) Areas of shallow flooding. In these areas, base flood depth ranges from one to three feet, a clearly defined channel does not exist, the path of flooding is unpredictable and indeterminate, and velocity flow may be evident.
