Amendments to Storm Water Ordinance

Houston Public Works (HPW) is responsible for storm water discharge into the municipal separate storm water sewer system (MS4) within the City. In order to comply with changes to the City's forthcoming MS4 permit with the Texas Commission on Environmental Quality, amendments to Chapter 47 of the Code of Ordinances, which includes the City's Storm Water Discharge Ordinance, were passed and adopted by City Council.

Of significant impact to customers are the revised definitions to Section 47-601. The acreage requirement for new development was reduced from 5 acres to 1 acre or larger for an undeveloped parcel of land. The acreage requirement for significant redevelopment was amended to an increase of 0.2 acre or more to the impervious cover on a developed parcel for land one acre or larger.

All projects submitted to the City of Houston on or after February 5, 2018 will be subject to the new definitions and will require a Storm Water Quality (SWQ) permit from HPW's Office of the City Engineer.
