The Village Council shall take into account flood hazards, to the extent that they are known, in all official actions by the Council related to land management, use and development.
A. New subdivisions and annexation agreements within the SFHA shall be reviewed to assure that the proposed developments are consistent with Sections 15.68.050, 15.68.060, 15.68.070 and 15.68.080 of this chapter and the need to minimize flood damage. Plats or plans for new subdivisions shall include a signed statement by and Illinois Registered Professional Engineer that the plat or plans account for changes in the drainage of surface waters in accordance with the Plat Act (765 ILCS Act 205).
B. Proposals for new subdivisions and additions to subdivisions shall include base flood or one hundred (100) year frequency flood elevation data and floodway delineations. Where this information is not available from an existing study filed with the Illinois State Water Survey, the applicant's Registered Professional Engineer shall be responsible for calculating the base flood or one hundred (100) year frequency flood elevation pursuant to Section 15.68.040(D) of this chapter and submitting it to the State Water Survey and IDNR/OWR for review and approval as best available regulatory data.
C. New streets, blocks, lots, parks and other public grounds shall be located and laid out in such a manner as to preserve and utilize natural streams and channels. Wherever possible, the floodplains shall be included within parks or other public grounds.
D. The Village Council shall not approve any annexation agreement or any plat of subdivision located outside the corporate limits unless such agreement or plat is in accordance with the provisions of this chapter.
