A. This section 11-16-4 sets forth requirements for developments within floodplains and floodways. In addition, developments in the SFHA draining more than one square mile with no designated floodway must meet IDNR/OWR Ill. Adm. Code part 3700 Rules. References to IDNR/OWR permits or approvals in this section shall be construed as "their designee" where a portion or all their authority has been delegated.
B. Development that qualifies for any of the self-issuing Statewide or regional permits administered by IDNR/OWR (Statewide permit nos. 1 through 14 and regional permit no. 3) are similarly permitted under this section 11-16-4. The developer need only submit to the Administrator information as shall show the Administrator that the development qualifies for the particular Statewide or regional permit in question under the regulations established by IDNR/OWR for the permit and no further submittal need be made under this section 11-16-4. All other provisions of this chapter applicable to the development, however, continue to apply. However, a permit from the County or the certified community must still be issued.
C. All development shall meet the requirements set forth in table 1 of this section. The table is intended only as a guide to indicate the applicable chapter sections for development in floodplains.
