Think Carefully About Variances Your community must assure that some very specific conditions are satisfied in order for a proposal to qualify for a variance. BFE LOWEST FLOOR BELOW BFE A variance to build below the BFE may be granted, but flood insurance will be very expensive – perhaps more than $1,500 per year (see page 18)! A variance to build below the base flood elevation could expose your family and future owners to more damage and unsafe conditions. Post-FIRM building, not elevated Some variances are issued with special conditions. You must comply or you could be cited for a violation. Think carefully about seeking a variance to build below the base flood elevation. Not only will your property be more likely to get damaged, but insurance will be very costly. 34 ILLINOIS QUICK GUIDE
Paperwork is Important – for You and Your Community ELEVATION CERTIFICATE Lowest Adjacent Grade Higher Than BFE COMPACTED FILL If you get a permit to build in the floodplain, you will be given an Elevation Certificate form. As soon as your lowest floor is set, get the form filled out by a surveyor or engineer. This form is important! It proves that you built correctly, and it can be used to get the lowest cost flood insurance. 35 ILLINOIS QUICK GUIDE
