(A) The Town Council, on 11-6-2000, adopted Ord. 2000-21, which established “The Town of Zionsville Subdivision Control Ordinance”, commonly known as the “Subdivision Control Ordinance”, in order to control runoff of storm water and to protect, conserve and promote the orderly development of the land in the town and its water resources. This code was primarily targeted at the overall administration of policies regarding the development and re-development of land within the town. On 10-4-2004, the Town Council adopted amendments to the design and construction standards of the town to govern specific technical issues in regard to new developments and re-developments. The town relied upon the County Soil and Water Conservation District, engineering review and developer submittals to determine compliance with applicable laws of the state in regard to erosion control and pre- and post-development drainage plans.
(B) On 12-8-1999, Phase II of the National Pollutant Discharge Elimination System (NPDES) permit program was published in the Federal Register. The NPDES program, as authorized by the 1972 amendments to the Clean Water Act, controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Phase II of NPDES requires permit coverage for storm water discharges from regulated small municipal separate storm sewer systems (MS4s) and for small construction activity that results in the disturbance of equal to or greater than one acre. This federal regulation went into effect 3-10-2003. In response to Phase II of NPDES, the State Department of Environmental Management enacted Rule 13 (327 I.A.C. 15-13) and revised Rule 5 (327 I.A.C. 15-5).
(C) Under these new state and federal regulations, the town is required to establish a regulatory mechanism for regulating storm water quality management. Therefore, this document was created to supplement the town’s subdivision control ordinance and the design and construction standards to address storm water quality and quantity.
