§ 152.04 DUTIES OF ENFORCEMENT OFFICIAL.
   The Community Development Director 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 for which a detailed study has not been conducted and which drains more than 1 square mile. Check whether the development is potentially within an extended SFHA (with a drainage area less than 1 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 for which a detailed study has not been conducted and which drains more than 1 square mile, the permit shall be referred to a registered professional engineer under the employ or contract of the Village for review to ensure that the development meets § 152.07 or 152.08. In the case of an appropriate use, the P.E. shall state in writing that the development meets the requirements of § 152.07.
   (C)   Dam safety requirements. Dams are classified as to their size and their hazard/damage potential in the event of failure. The construction or major modification of all Class I (high hazard) and Class II (moderate hazard) dams require an IDNR/OWR dam safety permit. Some Class III (low hazard) dams require an IDNR/OWR dam safety permit, depending on the drainage area to the dam, the height of the dam and the impounding capacity behind the dam. Most off-channel detention basins that have an embankment are non-jurisdictional Class III dam. It is not required that IDNR/OWR “sign off” on all non-jurisdictional Class III dams. A consulting engineer with dam safety knowledge can estimate a hazard classification and determine if an IDNR/OWR dam safety permit is required. A permit application submittal must be made to IDNR/OWR for the construction or major modification of jurisdictional dams. Regulated dams may include weirs, restrictive culverts or impoundment structures.
   (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 compliance with the provisions of this chapter and schedule on an annual basis an inspection of the floodplain and document the results of the inspection.
   (G)   Damage determinations. Make damage determinations of all damaged buildings in the SFHA after a flood to determine substantially damaged structures which must comply with § 152.09(C)(3).
   (H)   Elevation and floodproofing certificates. Maintain in the permit files an elevation certificate certifying the elevation of the lowest floor (including basement) of a residential or non-residential building subject to § 152.09, and/or the elevation to which a non-residential building has been floodproofed, using a floodproofing certificate, for all buildings subject to § 152.09.
   (I)   Records for public inspection. Maintain for public inspection and furnish upon request base flood data, SFHA and designated 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 and/or elevation certificates for all buildings constructed subject to this chapter.
   (J)   State permits. Ensure that construction authorization has been granted by IDNR/OWR, for all development projects subject to §§ 152.07 and 152.08, unless enforcement responsibility has been delegated to the Village. 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;
      (2)   IDNR/OWR projects, dams or impoundment structures as defined in § 152.02 and all other state, federal or local unit of government projects, including projects of the Village and County, except for those projects meeting the requirements of § 152.07(B)(10);
      (3)   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 § 152.07(B)(6)(e);
      (4)   An engineer’s analysis of the flood profile due to § 152.07(B)(6)(d);
      (5)   Alternative transition sections and hydraulically equivalent compensatory storage as indicated in § 152.07(B)(6)(a), (b) and (h);
      (6)   Permit issuance of structures within, under, or over publicly navigable rivers, lakes and streams;
      (7)   Any changes in the base flood elevation or floodway locations; and
      (8)   Base flood elevation determinations where none now exist.
   (K)   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 IDNR/OWR and FEMA for proposed revisions of a regulatory map within 6 months whenever a modification of the floodplain may change the base flood elevation or result in a change to the floodplain map. Submit reports as required for the National Flood Insurance Program, and notify FEMA of any proposed amendments to this chapter.
   (L)   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 IDNR/OWR and FEMA for any changes to this chapter.
