For issuance of an FDP in the floodway all new construction, substantial improvement, development or other use shall conform to the following standards:
A. Fill: No fill may be placed in the floodway.
B. Structures:
1. No structures shall be constructed within the floodway, with the following exceptions:
a. Open air pavilions for recreational purposes.
b. Recreational playground equipment.
2. Structures shall be firmly anchored to prevent flotation.
3. No pavement and/or impervious surface on private property are allowed within the floodway with the exception of recreational trails.
C. Subdivisions: See chapter 8 of this title.
D. Mechanical And Utility Equipment: All substantial improvement to mechanical and utility equipment including electrical, heating, ventilation, plumbing, air conditioning equipment, utility meters and other service facilities including water supply and wastewater disposal systems shall be elevated or floodproofed to at least one foot (1') above the base flood elevation and constructed of materials resistant to flood damage. All new and replacement on site waste disposal systems shall be located to prevent impairment to them or contamination from them during flooding.
E. Public Utilities: Public utilities and facilities such as sewer, gas, electric, and water systems shall be located and constructed to minimize or eliminate flood damage. Replacement public sanitary sewer systems and water supply systems shall be located and constructed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters.
F. Travel Trailers: All travel trailers (recreational vehicles) placed on property within the floodway shall be elevated with the lowest floor at or above the base flood elevation and be subject to elevation and anchoring requirements of "manufactured homes"; or be on site for less than one hundred eighty (180) consecutive days and be fully licensed and road ready. To be considered fully road ready, the trailer must be on wheels or a jacking system, be attached to the site only by quick disconnect type utilities and security devices, and have no permanently attached additions.
G. Variance Procedure: Upon application and after fifteen (15) days' notice of a public hearing, the city council may grant a floodplain variance subject to compliance with the provisions of section 60.6 of the NFIP rules and regulations, as amended, and such other conditions as the city council deems necessary to comply with the intent of this district. The issuance of variances shall be for floodplain management purposes only.
H. Watercourse Standards: The development services director shall notify adjacent communities and the Illinois department of natural resources, office of water resources and the federal insurance administration prior to any alteration or relocation of a watercourse. The flood carrying capacity within the altered or relocated portion of any watercourse shall be maintained.
I. Reports And Records:
1. The development services director shall provide the city council, the Illinois department of natural resources, office of water resources, and the federal insurance administration with an annual report on forms as provided by the federal insurance administration.
2. The planning services division shall maintain the records of lowest floor elevations, floodproofing certifications, permit applications, and all variance documents required by the federal insurance administration.
J. Disclaimer Of Liability: The degree of protection required by this section is considered reasonable for regulatory purposes and is based on available information derived from engineering and scientific methods of study. Larger floods may occur or flood heights may be increased by manmade or natural causes. This section does not imply that development either inside or outside the floodplain will be free from flooding or damage. This section does not create liability on the part of the city or any officer or employee thereof for any flood damage that results from proper reliance on this section or any administrative decision made lawfully thereunder.
K. Identification Required: It is a requirement of the NFIP that regulatory floodway is identified. Within any floodway identified on the flood insurance rate map, and within all other floodplains where a floodway has not been delineated, the following standards shall apply:
1. No development shall be allowed which, acting in combination with existing and anticipated development will cause any increase in flood heights or velocities or threat to public health and safety. These developments are outlined by the IDNR/OWR statewide permit 2-13.
2. The floodway for the floodplains of Crab Orchard Creek, Glade Creek, Little Crab Orchard Creek, Piles Fork Creek, and Carbondale Reservoir shall be as delineated on the countywide flood insurance rate map as prepared by FEMA. The floodways for each of the remaining floodplains of Carbondale shall be according to the best data available from federal, state, or other sources. (Ord. 2013-20)
