A stormwater management plan may be required if there is a collective net increase in impervious surface of two thousand (2,000) square feet or more or the existing building is demolished and a new structure constructed. The developer will have said stormwater management plan prepared by a professional engineer licensed in the State of Iowa, in conjunction with the submittal of a site plan, major modification, eligible minor modifications, or preliminary plat for the development of the property. The stormwater management plan shall comply with the City's current design standards for stormwater management. The method of stormwater management and the stormwater conveyance system shall be determined prior to City approval of a preliminary plat.
At time of any of the above actions, ownership and responsibility for all stormwater detention areas and private stormwater detention outlet structures will need to be established through the execution of a Stormwater Facility Maintenance Agreement. (Ord. 2243, 9-5-2017)
