MUNICIPAL STORM SEWER SYSTEM (MS4)
The MS4 Program addresses the quality of stormwater runoff. The goal of the MS4 Program is to provide a positive water quallity impact in our streams, rivers, and lakes. The MS4 Program is an unfunded mandate by the United States Environmental Protection Agency (EPA) and the Indiana Department of Environmental Management (IDEM) as part of the Phase II National Pollutant Discharge Elimination System (NPDES).
There are two ordinances that pertain to the MS4 Program:
Construction Site & Post Construction Stormwater Control Ordinance
#2007-1939.
Illicit Discharge and Connection Stormwater Ordinance
#2007-1940

STORM DRAINAGE AND SEDIMENT CONTROL ORDINANCE
The Storm Drainage & Sediment Control Ordinance addresses the quantity or the amount of storm water runoff. The goal of the Storm Drainage & Sediment Control Ordinance is to restrict the flow of storm water runoff to minimize the flooding of our storm sewer systems, streams and rivers. The Storm Drainage & Sediment Control Ordinance (97-1690) is an ordinance passed by the City of Plymouth Council in April of 1997.

ERU IMPERVIOUS AREA CALCULATION RATIONALE
GENERAL
The below scenarios are given to provide general guidelines on how hard surface areas were evaluated. Most hard surface areas were measured on City of Plymouth ortho photography at a scale of 1:600 utilizing ESRI Geographical Information System Software. A 95% reduction was taken in the measured areas to provide a factor of safety in making the measurements. Building permits, drainage plan applications and site plans were utilized to provide the areas on newer facilities not on the ortho photogaphy. If plan measurements were utilized a 95% reduction was applied. If applications and permits were utilized a reduction was not applied since the information was supplied by the owner or an owner’s representative.
All entities that have different facility locations will be billed for each facility location.
Hard surface areas include roofs, driveways and parking areas (asphalt, concrete, gravel, stone, etc), impervious coverings (material stacks, multiple vehicles, tarpaulins, etc), and similar items were all measured.
