The Village Board shall take into account flood hazards, to the extent that they are known, in all official actions related to land management, use and development.
(A) New subdivisions, manufactured home parks, travel trailer parks, annexation agreements, planned unit developments (PUDs) within the SFHA shall be reviewed to assure that the proposed developments are consistent with § 152.06 and the need to minimize flood damage. Plats or plans for new subdivisions, manufactured home parks and planned unit developments shall include a signed statement by a registered professional engineer that the plat or plan accounts for changes in the drainage of surface waters in accordance with the Plat Act.
(B) Proposals for new subdivisions, manufactured home parks, travel trailer parks, planned unit developments and additions to manufactured home parks and subdivisions shall include base flood or 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 engineer shall be responsible for calculating the base flood or 100-year frequency flood elevation, per § 152.05, and the floodway delineation, per the definition in § 152.02, and submitting it to the state water survey for review and approval as best available regulatory data.
(C) Streets, blocks, lots, parks and other public grounds shall be located and laid out in a manner as to preserve and utilize natural streams and channels. Wherever possible, the flood plains shall be included within parks or other public grounds.
(D) The Village Board shall not approve any PUD or plat of subdivision located outside the corporate limits unless the agreement or plat is in accordance with the provisions of this chapter.
