(A) No encroachments, including fill, new construction, substantial improvements or new development shall be permitted within a distance of 20 feet each side from top of bank or five times the width of the stream, whichever is greater, unless certification with supporting technical data by a registered professional engineer is provided demonstrating that such encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge.
(B) The BFE used in determining the regulatory flood protection elevation shall be determined based on one of the following criteria set in priority order.
(1) If base flood elevation (BFE) data is available from other sources, all new construction and substantial improvements within such areas shall also comply with all applicable provisions of this chapter and shall be elevated or flood-proofed in accordance with standards in § 151.40(B)(11) and (B)(12) of this chapter.
(2) All subdivision, manufactured home park and other development proposals located within special flood hazard areas shall provide base flood elevation (BFE) data if development is greater than five acres or has more than 50 lots/manufactured home sites. Such base flood elevation (BFE) data shall be adopted by reference per § 151.07 of this chapter to be utilized in implementing this chapter.
(3) When base flood elevation (BFE) data is not available from a federal, state or other source as outlined above, the reference level shall be elevated at least to highest above highest adjacent grade as stated in the regulatory flood protection elevation definition.
(Ord. passed 6-6-2005)
Along rivers and streams where BFE data is provided, but neither floodway nor non-encroachment areas are identified for a special flood hazard area on the FIRM or in the FIS report, the following requirements shall apply to all development within such areas:
(B) No encroachments, including fill, new construction, substantial improvements or other development, shall be permitted unless certification with supporting technical data by a registered professional engineer is provided demonstrating that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the community.
(Ord. passed 6-6-2005)
(A) Areas designated as floodways or non- encroachment areas are located within the special flood hazard areas established in § 151.07 of this chapter. The floodways and non-encroachment areas are extremely hazardous areas due to the velocity of flood waters that have erosion potential and carry debris and potential projectiles.
(1) No encroachments, including fill, new construction, substantial improvements and other developments shall be permitted unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood. Such certification and technical data shall be presented to the Floodplain Administrator prior to issuance of floodplain development permit.
(2) If § 151.29(A) of this chapter is satisfied, all development shall comply with all applicable flood hazard reduction provisions of this chapter.
(3) No manufactured homes shall be permitted, except replacement manufactured homes in an existing manufactured home park or subdivision; provided, the following provisions are met:
(a) The anchoring and the elevation standards of § 151.26(C) of this chapter; and
(b) The no encroachment standard of § 151.29(A) of this chapter are met.

(D) Certification requirements.
(1) Elevation certificates.
(a) An elevation certificate (FEMA Form 81-31) is required prior to the actual start of any new construction. It shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of the elevation of the reference level, in relation to mean sea level. Elevation certification shall be prepared by, or under direct supervision of, a registered land surveyor or professional engineer and certified by same. The Floodplain Administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder prior to the beginning of construction. Failure to submit the certification or failure to make required corrections shall be cause to deny a floodplain development permit.
(b) An elevation certificate (FEMA Form 81-31) or flood-proofing certificate (FEMA Form 81-65) is required after the reference level is established. Within seven calendar days of establishment of the reference level elevation, it shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of the elevation of the reference level, in relation to mean sea level. Elevation certification shall be prepared by, or under the direct supervision of, a registered land surveyor or professional engineer and certified by same. Any work done within the seven-day calendar period and prior to submission of the certification shall be at the permit holder’s risk. The Floodplain Administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder immediately and prior to further progressive work being permitted to proceed. Failure to submit the certification or failure to make required corrections shall be cause to issue a stop-work order for the project.
(c) A final as-built elevation certificate (FEMA Form 81-31) is required after construction is completed and prior to certificate of compliance/ occupancy issuance. It shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of final as-built construction of the elevation of the reference level and all attendant utilities. Elevation certification shall be prepared by, or under the direct supervision of, a registered land surveyor or professional engineer and certified by same. The Floodplain Administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder immediately and prior to certificate of compliance/ occupancy issuance. In some instances, another certification may be required to certify corrected as- built construction. Failure to submit the certification or failure to make required corrections shall be cause to withhold the issuance of a certificate of compliance/ occupancy.
(2) Flood-proofing certificate. If non- residential flood-proofing is used to meet the regulatory flood protection elevation requirements, a flood-proofing certificate (FEMA Form 81-65) is required prior to the actual start of any new construction. It shall be the duty of the permit holder to submit to the Floodplain Administrator a certification of the flood-proofed design elevation of the reference level and all attendant utilities, in relation to mean sea level. Flood-proofing certification shall be prepared by or under the direct supervision of a professional engineer or architect and certified by same. The Floodplain Administrator shall review the certificate data submitted. Deficiencies detected by such review shall be corrected by the permit holder prior to the beginning of construction. Failure to submit the certification or failure to make required corrections shall be cause to deny a floodplain development permit. Failure to construct in accordance with the certified design shall be cause to withhold the issuance of a certificate of compliance/ occupancy.
(3) Foundation certification. If a manufactured home is placed within Zone A, AO, AE or A1-30 and the elevation of the chassis is more than 36 inches in height above grade, an engineered foundation certification is required per § 151.26(C) of this chapter.
(4) Other submissions. If a watercourse is to be altered or relocated, a description of the extent of watercourse alteration or relocation; an engineering report on the effects of the proposed project on the flood-carrying capacity of the watercourse and the effects to properties located both upstream and downstream; and a map showing the location of the proposed watercourse alteration or relocation shall all be submitted by the permit applicant prior to issuance of a floodplain development permit.
(5) Certification exemptions. The following structures, if located within Zone A, AO, AE or A1-30, are exempt from the elevation/flood-proofing certification requirements specified in divisions (D)(1) and (D)(2) above:
(a) Recreational vehicles meeting requirements of § 151.26(F)(1) of this chapter;
(b) Temporary structures meeting requirements of § 151.26(G) of this chapter; and
(c) Accessory structures less than 150 square feet meeting requirements of § 151.26(H) of this chapter.
