A copy <br />of the notification must also be submitted to the Chicago Regional Office of the Federal <br />Emergency Management Agency (FEMA). <br />(g)Notification to FEMA when physical changes increase or decrease base flood <br />elevations. As soon as practicable, but not later than six months after the date such <br />supporting information becomes available, the Zoning Administrator must notify the <br />Chicago Regional Office of FEMA of the changes by submitting a copy of the relevant <br />technical or scientific data. <br />(3) Variances.

Variances may only be issued by a community Lapon (i) a showing of good and <br />sufficient cause, (ii) a determination that failure to grant the variance would result in <br />exceptional hardship to the applicant, and (iii) a determination that the granting of a <br />variance will not result in increased flood heights, additional threats to public safetL <br />extraordinary public expense, create nuisances, cause fraud on or victimization of the <br />public, or conflict with existing local laws or ordinances. <br />3. Variances may only be issued upon a determination that the variance is the <br />minimum necessary, considering the flood hazard, to afford relief. <br />(c) Flood insurance notice. The Zoning Administrator must notify the applicant <br />for a variance that: 1) The issuance of a variance to construct a structure below the base <br />flood level will result in increased premium rates for flood insurance up to amounts as <br />high as $25 for $100 of insurance coverage; and 2) Such construction below the base or <br />regional flood level increases risks to life and property.
