The city engineer 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 an SFHA, determine whether they are in a floodway, flood fringe or floodplain on which a detailed study has not been conducted which drains more than one square mile.
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 (PE) under the employ or contract of the city for review to ensure that the development meets the requirements of section 7-1-8 1 of this chapter. In the case of an appropriate use, the PE shall state in writing that the development meets the requirements of section 7-1-8 of this chapter.
C. Dam Safety Requirements: Ensure that a DWR dam safety permit has been issued or a letter indicating no dam safety permit is required, if the proposed development activity includes construction of a "dam" as defined in section 7-1-3 of this chapter. 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 city 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 that 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) of a residential or nonresidential building or the elevation to which a nonresidential building has been floodproofed, using a floodproofing certificate, for all buildings subject to section 7-1-10 of this chapter 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 Illinois division of water resources, for all development projects subject to sections 7-1-8 and 7-1-9 of this chapter, unless enforcement responsibility has been delegated to the city. Upon acceptance of this chapter by DWR and FEMA, responsibility is hereby delegated to the city as per 91 Illinois administrative code 708 for construction in the regulatory floodway and floodplain when floodways have not been defined in sections 7-1-8 and 7-1-9 of this chapter. However, the following review approvals are not delegated to the city and shall require review or permits from DWR:
1. Organizations which are exempt from this chapter, as per the Illinois Compiled Statutes.
2. Department of transportation projects, dams or impoundment structures as defined in section 7-1-3 of this chapter and all other state, federal or local unit of government projects, including projects of the city and county, except for those projects meeting the requirements of section 7-1-8 of this chapter.
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 subsection 7-1-8-2L1e of this chapter.
4. An engineer's analysis of the flood profile due to subsection 7-1-8-2L1d of this chapter.
5. Alternative transition sections and hydraulically equivalent compensatory storage as indicated in subsections 7-1-8-2L1a, L1b and L1h of this chapter.
6. Permit issuance of structures within 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.
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 DWR and the federal emergency management agency for proposed revisions of a regulatory map. Submit reports as required for the national flood insurance program. Notify the federal emergency management agency 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 DWR and FEMA for any chapter changes. (Ord. 0-90-37, 8-20-1990)
