(Ord. 21-33, passed 2-22-2021)
Pursuant to the purpose and methods of reducing flood damage stated in these regulations, the following additional standards are adopted to assure that the reduction of the flood carrying capacity of watercourses is minimized.
(a) Development in floodways.
(1) In floodway areas, development shall cause no increase in flood levels during the occurrence of the base flood discharge. Prior to issuance of a floodplain development permit, the applicant must submit a hydrologic and hydraulic analysis, conducted by a registered professional engineer, demonstrating that the proposed development would not result in any increase in the base flood elevation; or
(2) Development in floodway areas causing increases in the base flood elevation may be permitted provided all of the following are completed by the applicant:
A. Meet the requirements to submit technical data in § 1476.21(a);
B. An evaluation of alternatives, which would not result in increased base flood elevations and an explanation why these alternatives are not feasible;
C. Certification that no structures are located in areas that would be impacted by the increased base flood elevation;
D. Documentation of individual legal notices to all impacted property owners within and outside the community, explaining the impact of the proposed action on their property; and
E. Concurrence of the Mayor of the city and the chief executive officer of any other communities impacted by the proposed actions.
(b) Development in riverine areas with base flood elevations but no floodways.
(1) In riverine special flood hazard areas identified by FEMA where base flood elevation data are provided but no floodways have been designated, the cumulative effect of any proposed development, when combined with all other existing and anticipated development, shall not increase the base flood elevation more than one foot at any point. Prior to issuance of a floodplain development permit, the applicant must submit a hydrologic and hydraulic analysis, conducted by a registered professional engineer, demonstrating that this standard has been met; or
(2) Development in riverine special flood hazard areas identified by FEMA where base flood elevation data are provided but no floodways have been designated causing more than one foot increase in the base flood elevation may be permitted provided all the following are completed by the applicant:
A. An evaluation of alternatives which would result in an increase of one foot or less of the base flood elevation and an explanation why these alternatives are not feasible; and
B. Division (a)(2)A. and (a)(2)C. through (a)(2)E. of this section.
(c) Alterations of a watercourse. For the purpose of these regulations, a watercourse is altered when any change occurs within its banks. The extent of the banks shall be established by a field determination of the “bankfull stage”. The field determination of “bankfull stage” shall be based on methods presented in Chapter 7 of the USDA Forest Service General Technical Report RM-245, Stream Channel Reference Sites: An Illustrated Guide to Field Technique or other applicable publication available from a federal, state or other authoritative source. For all proposed developments that alter a watercourse, the following standards apply.
(1) The bankfull flood carrying capacity of the altered or relocated portion of the watercourse shall not be diminished. Prior to the issuance of a floodplain development permit, the applicant must submit a description of the extent to which any watercourse will be altered or relocated as a result of the proposed development, and certification by a registered professional engineer that the bankfull flood carrying capacity of the watercourse will not be diminished.
(2) Adjacent communities, the U.S. Army Corps of Engineers, and the Ohio Department of Natural Resources, Division of Water, must be notified prior to any alteration or relocation of a watercourse. Evidence of such notification must be submitted to the Federal Emergency Management Agency.
(3) The applicant shall be responsible for providing the necessary maintenance for the altered or relocated portion of said watercourse so that the flood carrying capacity will not be diminished. The Floodplain Administrator may require the permit holder to enter into an agreement with the city specifying the maintenance responsibilities. If an agreement is required, it shall be made a condition of the floodplain development permit.
(4) The applicant shall meet the requirements to submit technical data in § 1476.21(a)(1)C. when an alteration of a watercourse results in the relocation or elimination of the special flood hazard area, including the placement of culverts.
(Ord. 21-33, passed 2-22-2021)
The requirements of this section apply to development in coastal high hazard areas designated Zone V or VE on the community’s effective FIRM (and when designated on a preliminary or final FIRM issued by FEMA under the circumstances provided in § 1476.23).
(a) All new construction and substantial improvements shall be elevated on pilings or columns that may be armored as necessary to withstand Lake Erie ice forces so that:
(1) The bottom of the lowest horizontal structural member supporting the lowest floor (excluding the pilings or columns) is elevated to or above the flood protection elevation, and
(2) The pile or column foundation and structure attached thereto is anchored to resist flotation, collapse and lateral movement due to the effects of wind and water loads acting simultaneously on all building components.
A. Water loading values shall be those associated with the base flood.
B. Wind loading values shall be those defined according to American Society of Civil Engineers 7-13 Minimum Design Loads and Associated Criteria for Buildings and Other Structures, or current version adopted by Ohio Board of Building Standards.
C. A registered professional engineer or architect shall develop or review the structural design, specifications and plans for the construction, and shall certify that the design and methods of construction to be used are in accordance with accepted standards of practice for meeting the provisions of division (a)(1) and (a)(2) of this section.
(b) All new construction and substantial improvements shall have the space below the lowest floor either free of obstruction or constructed with non-supporting breakaway walls, open wood latticework, or insect screening intended to collapse without causing collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system.
(1) For the purpose of division (b) of this section, a breakaway wall shall have a design safe loading resistance of not less than ten and no more than 20 pounds per square foot.
(2) Use of breakaway walls which exceed a design safe loading resistance of 20 pounds per square foot (either by design or where so required by local or state codes) may be permitted only if a registered professional engineer or architect certifies that the designs proposed meet all the following conditions:
A. Breakaway wall collapse shall result from a water load less than that which would occur during the base flood; and
B. The elevated portion of the building and supporting foundation system shall not be subject to collapse, displacement, or other structural damage due to the effects of wind and water loads acting simultaneously on all building components (structural and non-structural). Water loading values shall be those associated with the base flood. Wind loading values shall be those defined according to American Society of Civil Engineers 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures, or equivalent standard.
(3) All space enclosed by breakaway walls, open wood latticework, or insect screening below the lowest floor shall be used solely for parking of vehicles, building access, or storage.
(c) The use of fill or redistributed existing fill, placed after the initial identification of Zones V, VE or V1-30 on the community’s FIRM, for structural support of buildings is prohibited.
(d) Alteration of sand dunes that will increase potential flood damage is prohibited.
(e) Placement or substantial improvement of manufactured homes must comply with divisions (a) through (e) of this section.
(f) Recreational vehicles must either:
(1) Be on site for fewer than 180 consecutive days;
(2) Be fully licensed and ready for highway use; or
(3) Comply with divisions (a) through (e) of this section.
(Ord. 21-33, passed 2-22-2021)
(a) The city Council shall establish a Board of Appeals appointed to serve as the Appeals Board. The members of such Board shall consist of the members of the Zoning Board of Appeals for these regulations as established by the Avon Lake Zoning Code, § 1212.02(d).
