The Wayne County Storm Water Management Ordinance (Enrolled Ordinance No. 2006-1114A) and Administrative Rules (Resolution No. 2006-1114B) assist in compliance with the mutual requirements of the County, local government, and other public agencies under the federal Phase 2 NPDES storm water regulations. These requirements include the development, implementation, and enforcement of programs to manage storm water from new development and re-development. By managing storm water, we will help to minimize flooding problems, erosion, and loss of or damage to natural resources. A partnership between the County, local government, and other agencies who influence development and storm water management will ensure that such a program is effective. The Wayne County storm water management regulations, adopted on October 19, 2000 by the Wayne County Commission, and subsequently amended in August 2003 and December 2006, consist of the following documents:
Which Types of Development Projects Do the Ordinance and Rules Apply To?
Persons intending to engage in these activities are required to apply for and obtain a storm water construction approval from the County prior to commencing onsite work. What Do the Rules Generally Require for Development Projects? Under the Wayne County Storm Water Management Program, storm water management systems must be selected and designed with two main objectives: flood control and water resources protection. Minimum performance standards that storm water management systems must achieve to meet these objectives are:
Wayne County has established general design standards to be met by all storm water management systems, and specific design standards to be met by certain components of storm water management systems. These standards help ensure that each component is designed, operated and maintained such that the performance standards are met. Chapters 6, 7, and 8 of the Standards Manual provide detailed information about standards and guidance for designing storm water management system components to satisfy the performance standards. The Wayne County Storm Water Management Ordinance and Administrative Rules were deliberately written as a performance-based program in order to provide developers with flexibility to design storm water management systems to best fit the situation at each site. Developers and designers of storm water management systems in Wayne County may select any combination of storm water management elements which meet the performance standards provided that the designer's selection: (1) complies with other requirements of the Ordinance, Administrative Rules, and Standards, (2) complies with other applicable local, state, and federal requirements, and (3) does not conflict with existing local storm water management plans. Wayne County has published our "Storm Water Management Standards" manual to provide developers/designers with information on the variety of management practices available to meet the performance standards of the Wayne County Storm Water Management Ordinance and Administrative Rules. How Will The Storm Water Management Systems be Maintained? The Wayne County Ordinance and Administrative Rules require storm water management systems to be maintained in perpetuity to ensure that they function effectively as designed. A public entity, such as a local unit of government or a drainage district established under the Michigan Drain Code, must assume long-term maintenance responsibility for storm water management systems that require a Wayne County storm water construction approval. This maintenance responsibility must be assumed through a legally-binding instrument (such as an ordinance, resolution, contract, or equivalent instrument approved by the County) as a condition of final project approval. Long-term maintenance generally begins when construction of the storm water system is complete and the storm water construction approval is released. The public entity may perform the long-term maintenance of a storm water management system itself, or it may designate another entity (such as a homeowner's association, condominium association, or property owner) to undertake this responsibility. However, even if the responsibility for maintenance activities is designated to another entity, the public entity identified in the long-term maintenance permit remains ultimately responsible for ensuring that the required maintenance is performed. The Wayne County Storm Water Management Ordinance and Administrative Rules are implemented through the existing review and permit processes of the Permit Office of the Wayne County Department of Public Services, Engineering Division. Copies of the ordinance, rules, or standards manual are available through the Permit Office (33809 Michigan Avenue; Wayne, MI 48184; (734) 595-6504) or from Wayne County's web sites: "www.waynecounty.com" or "http://www.wcdoe.org". Additionally, the standards manual, which accompanies the Storm Water Ordinance, can be found by clicking here. In addition to the County’s program, local communities are required under the new storm water regulations to manage storm water from development and re-development projects under their purview. Options to local communities for complying with this requirement include:
