Phase II Stormwater Management Plan

The purpose of the City of Troy Phase II Stormwater Management Plan is to improve area water quality by preventing harmful pollutants from being carried by stormwater runoff into local water bodies.

Best Management Practices (BMPs) are methods to prevent or reduce the pollutants in stormwater runoff. Our City of Troy Phase II Stormwater Management Plan (SWMP) includes BMPs that address potential sources of pollutants in stormwater as required by the federal and state regulations. The implementation of BMPs in the SWMP will satisfy the six Minimum Control Measures (MCMs) required by the Phase II Regulations.

City of Troy Stormwater Management Plan

These six minimum control measures are:

I. Public Education and Outreach

The Plan implements a public education program to distribute educational materials to the community and conduct outreach activities about the impacts of stormwater discharges on water bodies and the steps that the public can take to reduce pollutants in stormwater runoff.

II. Public Involvement and Participation

The public is actively involved in implementation of the stormwater management program through community groups of all kinds and participation in activities to reduce stormwater pollution.

III. Illicit Discharge Detection and Elimination

City of Troy is in the process of developing and implementing a program to detect and eliminate illicit discharges into our MS4 and area streams. We are developing a map of the area streams, storm sewers and storm sewer outfalls.

IV. Construction Site Stormwater Runoff Control

Land disturbance programs must be implemented to reduce pollutants in storm water runoff from construction activities that disturb the land. The BMPs required by the program focus primarily on erosion and sediment control.

V. Post-Construction Stormwater Management

A program to address stormwater runoff from new development and redevelopment projects must be implemented to reduce pollutants in stormwater runoff from developed property. The program must ensure that BMPs are in place to prevent or minimize water quality impacts. Structural BMPs include stormwater detention ponds, infiltration basins, filter strips and more.

VI. Pollution Prevention/Good Housekeeping for Municipal Operations

An operation and maintenance program that has the ultimate goal of preventing or reducing pollutant runoff from municipal operations will be implemented.



City of Troy cannot keep our waterways clean alone. It needs the support, resources, and actions of concerned citizens and businesses to improve local water quality. Since our waterways and sewers are shared public resources, there are many steps that you can take to help maintain both.

Residents can:

  • Disconnect rain gutters and downspouts from nearby sewer lines
  • Install a rain garden or rain barrel to capture stormwater runoff
  • Avoid planting trees, shrubs and bushes on your property near the sewer line. As plants’ roots deepen, they can enter, block and damage sewers
  • Reduce your water use, especially during rainy weather
  • Reduce fertilizer and pesticide use and lawn watering
  • Properly dispose of household hazardous waste like cleaning products, motor oil and paints
  • Collect and dispose of trash and pet waste properly
  • Reduce impervious surfaces (blacktop, concrete, etc.) on your property where possible.



Dirt, oil, and trash that collect in parking lots and paved areas can be carried by stormwater runoff into a storm sewer and eventually reach local water bodies.


  • Disconnect rain gutters and downspouts from nearby sewer lines
  • Sweep up litter, trash, and dirt from sidewalks, driveways, and parking lots, especially from around storm drains.
  • Keep lids closed on grease storage containers and trash dumpsters so stormwater will not be contaminated. Make sure the containers are not leaking.
  • Businesses should provide an adequate number of appropriately sized containers.
  • Owners of commercial dumpsters should be certain their containers are of adequate size to handle the waste they generate. Trash receptacles and dumpsters should be emptied on an appropriate schedule.
  • Keep chemicals and other materials stored onsite under cover to prevent contaminating runoff.
  • Use all chemicals responsibly and properly dispose of wastes.
  • Ensure the proper disposal of all wastewater into the wastewater sewer system.
  • Report any chemical or oil spill to emergency response agencies. Be prepared for spill incidents to keep spills from harming the environment.



  • Minimize the amount of exposed soil and divert stormwater away from disturbed or exposed areas of the construction site.
  • Install best management practices (BMPs) such as silt fences, vegetative cover and other sediment and erosion controls, and properly maintain them.
  • Wash mud from vehicles in areas where the water will not enter the storm sewer or run to a nearby water body.
  • Properly dispose of trash and other wastes.

Automotive/Vehicle Washing


  • Provide cover over fueling stations and provide for spill containment.
  • Wash vehicles at a commercial wash or other properly designated facility that treats its wastewater before sending it to the wastewater sewer.
