Protecting Stormwater Ponds

Stormwater PondStormwater ponds and wetlands are designed to intercept and treat stormwater runoff.

Algae blooms or aquatic plants in ponds and lakes need nutrients to grow. Pollutants or nutrients entering a pond through stormwater runoff can lead to large algae blooms, excess plant growth or even hurt wildlife.

An overabundance of plant and algae growth may inhibit a stormwater pond’s function and degrade the pond’s water quality. More importantly, however, the degradation of a stormwater pond results in polluting the watershed, or drainage area, around a lake, stream, wetland or pond. This negatively affects water quality, which has an adverse effect on plant and animal life, and decreases the recreational potential for these bodies of water.

Pollutants that could be washed into our ponds include:

  • Lawncare products such as fertilizers or pesticides
  • Animal debris or waste
  • Lawn clippings
  • Oils, greases and automotive additives
  • Dust and dirt from construction, streets or rainfall
  • Wind-blown chemicals
Property Owner Responsibility
  • Pick up or rake up trash, leaves and grass from yards, streets and curbs.
  • Never dispose of yard waste (or anything else) into ponds and storm drains – the waste contains phosphorus, which causes plants and algae to grow.
  • Remove trash, leaves and grass from yards, streets and curbs.
  • Use biodegradable soaps for outdoor cleaning or car washing.
  • Sweep driveways and sidewalks instead of hosing them off.
  • Pick up pet waste and dispose of it in the trash.
  • Maintain healthy sod and grass to limit erosion. Reseed or re-sod all bare areas to keep stormwater from washing soil particles, which also contain phosphorus, into a storm sewer or pond.

City Responsibility

The City does not treat stormwater ponds or wetlands for algae, weeds, odors or other aesthetic problems; however, the City is responsible for the following tasks:

  • Maintenance of the “hydraulic and treatment function” of water resources that are located within City-owned property, drainage or utility easements.
  • Removal of sediment accumulation, obstructions and debris that impede the flow of water, and clearing clogged stormwater pipes.

Please contact the City with the following concerns:

Assistance with repairs
Utilities Division

Drainage concerns
Engineering Division

Vegetation management permit application or to report dumping of pollutants
Water Resources Coordinator
