Stormwater Ordinance and Design Manual
City of Madison Stormwater Management Ordinances:
The City of Madison regulates Stormwater Management through two ordinances.
The purpose of Chapter 54: STORMWATER REGULATIONS is to provide for the health, safety, and general welfare of the citizens of the City of Madison through the regulation of illicit discharges and construction site runoff. This chapter establishes methods for controlling the introduction of pollutants into the city's municipal separate storm sewer system (MS4) associated with illicit discharges. This chapter will also promote the public welfare by guiding, regulating and controlling the design, construction, use and maintenance of any development or other activity that disturbs or breaks the topsoil or results in the movement of earth on land in the city.
Chapter 55: POST-CONSTRUCTION STORMWATER REGULATIONS applies to all new development and redevelopment activities within the corporation limits of the City of Madison that would result in the disturbance of one or more acres of land, including land disturbing activities on individual lots of less than one acre that are part of a larger common plan of development. The site owner or developer of such a project shall develop a post-construction stormwater pollution prevention plan (SWPPP) which includes the provisions necessary for minimizing the impacts of pollutants from the proposed land use.
