The Administrative Department shall be responsible for the general administration and enforcement of this chapter which shall include the following:
(A) Determining the floodplain designation. Check all new development sites to determine whether they are in a Special Flood Hazard Area (SFHA). If they are in a SFHA, determine whether they are in a floodway, flood fringe or in a floodplain on which a detailed study has not been conducted which drains more than one square mile. Check whether the development is potentially within an extended SFHA (with a drainage area less than on square mile), indicating that the development would have adverse impacts regarding storage, conveyance, or inundation which would be the basis for the applicant being required to delineate the floodplain and floodway and be subject to the remaining sections of this chapter.
(B) Professional engineer review. If the development site is within a floodway or in a floodplain on which a detailed study has not been conducted which drains more than one square mile then the permit shall be referred to a registered professional engineer (P.E.) under the employ or contract of the village for review to ensure that the development meets the requirements of §§ 152.025 through 152.056. In the case of an appropriate use, the P.E. shall state in writing that the development meets the requirements of §§ 152.025 through 152.056.
(C) Dam safety requirements. Dams are classified as to their size and their hazard/damage potential in the event of failure. Permits for dams may be required from IDNR/OWR. Contact IDNR/OWR to determine if a permit is required. If a permit is required, a permit application must be made to IDNR/OWR prior to the construction or major modification of jurisdictional dams.
(D) Other permit requirements. Ensure that any and all required federal, state and local permits are received prior to the issuance of a floodplain development permit.
(E) Plan review and permit issuance. Ensure that all development activities within the SFHAs of the jurisdiction of the village meet the requirements of this chapter and issue a floodplain development permit in accordance with the provisions of this chapter and other regulations of this community when the development meets the conditions of this chapter.
(F) Inspection review. Inspect all development projects before, during and after construction to assure proper elevation of the structure and to ensure they comply with the provisions of this chapter.
(G) Elevation and floodproofing certificates. Maintain in the permit files an elevation certificate certifying the elevation of the lowest floor (including basement, walk-out and lookout foundations) of a residential or non-residential building or the elevation to which a nonresidential building has been floodproofed, using a floodproofing certificate, for all buildings subject to §§ 152.080 through 152.087 for public inspection and provide copies of same.
(H) Records for public inspection. Maintain for public inspection and furnish upon request base flood data, SFHA and regulatory floodway maps, copies of federal or state permit documents, variance documentation, Conditional Letter of Map Revision, Letter of Map Revision, Letter of Map Amendment and “as built elevation and floodproofing or elevation and floodproofing certificates for all buildings constructed subject to this chapter.
(I) State permits. Ensure that construction authorization has been granted by the IDNR-OWR, for all development projects subject to §§ 152.025 through 152.074, unless enforcement responsibility has been delegated to the village. Upon acceptance of this chapter by IDNR-OWR and FEMA, responsibility is hereby delegated to the village as per 17 Ill. Adm. Code, Chapter I, IDNR Part 3 708 for construction in the regulatory floodway and floodplain when floodways have not been defined in §§ 152.025 through 152.074. However, the following review approvals are not delegated to the village and shall require review or permits from IDNR-OWR:
(1) Organizations which are exempt from this chapter as per the Illinois Compiled Statutes;
(3) Approval of the hydraulic calculation for bridges and culverts; An engineer’s determination that an existing bridge or culvert crossing is not a source of flood damage and the analysis indicating the proposed flood profile, per § 152.089;
(4) An engineer’s analysis of the flood profile due to § 152.088;
(6) Permit for construction and other activities in public bodies of water pursuant to 17 Ill. Admin. Code 3708;
(7) Any changes in the base flood elevation or floodway locations; and
(8) An engineer’s determination that a proposed bridge affected by backwater from a downstream receiving stream may be built with a smaller opening.
(J) Cooperation with other agencies. Cooperate with state and federal floodplain management agencies to improve base flood or 100-year frequency flood and floodway data and to improve the administration of this chapter. Submit data to the IDNR-OWR and FEMA for proposed revisions of a regulatory map within six months whenever a modification of the floodplain may change the BFE or result in a change to the floodplain map. Submit reports as required for the National Flood Insurance Program. Notify FEMA of any proposed amendments to this chapter.
(K) Promulgate regulations. Promulgate rules and regulations as necessary to administer and enforce the provisions of this chapter, subject however to the review and approval of IDNROWR and FEMA for any chapter changes.
(L) Damage determinations. Make damage determinations of all damaged buildings in the SFHA after a flood to determine substantially damaged structures.
