(A) (1) Detailed plans, specifications, and all calculations for the control of stormwater runoff, as required by this chapter, shall be submitted to the Administrator for review when making application for the platting of any lands or for a building permit or special use permit for any mobile home, independent travel trailer, or recreational travel trailer park permit or for any planned community development permit; the plans, specifications, and calculations shall be submitted to and approved by the Administrator prior to the subdivision of any lands or the construction of any paved or compacted area designated to be used for loading, open storage, or the parking or movement of vehicles. Those exceptions found in § 151.05 are excluded.
(2) These plans shall show plan, profile, and cross-sections of the storage areas and excess stormwater passageways, including the areas expected to be inundated or covered with water.
(B) A plan for the responsibility of maintaining the stormwater storage areas shall be submitted to and approved by the Administrator prior to final approval. Acceptable plans for the maintenance of stormwater storage areas may include agreements with units of local government or school districts. Also acceptable would be agreements with individual property owners or property owners’ associations, in which case the Administrator may require that the face of the plat make reference to the agreement and that a restrictive covenant running with the land be imposed on all affected property. If a property owners’ association is to be established, the developer of the project or subdivision or the applicant shall be responsible for its establishment and for informing the individual property owners of their responsibilities. Acceptable methods of fixing the responsibility for maintaining stormwater storage areas are not limited to those described above.
(C) The facilities for the control of stormwater runoff shall be constructed prior to, if possible, the start of any construction or during the earliest possible stage construction on the site of the project. All costs of construction, including the restoring, temporary seeding, and permanent erosion control measures, shall be borne by the contractor, applicant, or developer. The Administrator shall approve the erosion control measures and the timing of their installation prior to their accomplishment.
(D) The construction of the stormwater storage area and excess stormwater passageway shall be under the supervision of an Illinois registered professional engineer. He or she shall be responsible for all construction in accordance with the approved plans. A set of as-built plans shall be submitted to the Administrator for his or her approval upon completion of the construction of the stormwater storage area and excess stormwater passageway.
(E) All applications for building permits shall contain a statement that the building or structures and appurtenances connected therewith include facilities for the orderly runoff or retention of rain and melting snow, as required herein. Plans submitted with the application shall include a signed statement issued by an Illinois registered professional engineer that the plans include facilities adequate to prevent harmful runoff, as required herein. For single-family dwellings to be located in a subdivision meeting the requirement of this chapter, the signed statement may, in lieu of the above procedure, be placed on the face of the final plat.
(F) A bond or other acceptable method of assurance in an amount sufficient to cover the estimated cost of all the construction required by this chapter shall be required prior to the start of any construction on the project. Proof of the assurance shall be given to the Administrator for his or her records.
(G) In the event that stormwater runoff control can be provided exceeding the requirements of this chapter and the benefit of this additional control would accrue to the Village at large, the Village may participate in the increased cost of the control of stormwater runoff in proportion to the additional benefits derived therefrom.
