STORMWATER MANAGEMENT

The stormwater management program is a state mandated program. Historically, runoff from development was only managed during the construction phase of a project through sediment control practices. Stormwater management structures, or best management practices (BMPs) were developed to manage stormwater runoff after the construction phase of the project has been completed. Examples of BMPs are infiltration, flow attenuation, retention, extended detention and detention.

Pollution Prevention

When it rains, a portion of the rainwater or stormwater flows over the land into the storm drain and discharges directly to our streams, rivers, and ultimately the Chesapeake Bay. Stormwater unlike sewage is not treated before it discharges to the stream. As it travels over land, stormwater comes in contact with many substances. These substances may have a significant impact on the storm drain system and stream water quality. Some of the effects are flooding, clogging, property damage, and endangerment to aquatic life, recreation and drinking water.

Tips for Keeping a Clean Environment

  • Report any dumping of inappropriate materials into storm water drains (such as oil, antifreeze) to your local municipal officials.
  • Use good housekeeping practices with lawn care chemicals, oil, gasoline, pet wastes, etc.
  • Help to start or participate in programs to recycle and safely dispose of used oils and household hazardous wastes and containers.
  • Tell others about pollution runoff and storm water runoff and what they can do to help.
  • Plant trees, shrubs and ground cover to protect bare soil and reduce runoff.
  • Create a “rain garden” to keep rain water in your yard to replenish plants.
  • Try composting to recycle yard wastes and reduce fertilizer use.
  • Find alternatives to the chemicals you use on your lawn.

 

What is a rain barrel?

A rain barrel is a system that collects and stores rainwater from your roof that would otherwise be lost to runoff and diverted to storm drains and streams. Usually, a rain barrel is composed of a 55 gallon drum, a vinyl hose, PVC couplings, a screen grate to keep debris and insects out, and other off-the-shelf items. A rain barrel is relatively simple and inexpensive to construct and can sit conveniently under any residential gutter down spout.

STORMWATER MANAGEMENT PROJECTS – CURRENTLY IN THE WORKS:

The Concord Point Park Pond Retrofit is currently being designed to improve the existing Stormwater Management Facility adjacent to Heron Harbor Condominiums and located within Concord Point Park.

David R. Craig Park –The design of a plan to treat runoff from the parking lot and Warren Street within the David R. Craig Park is in the works and will also beautify the area with unique soil layers and native plantings.

City of Havre de Grace Water Treatment Plant – The design is being drawn for special soils and native plantings to treat runoff from the parking lot behind the City of Havre de Grace Water Treatment Plant and along the banks of the River.

Lilly Run Phase I Wetland Enhancement – The Engineering is currently underway to remove sediment, widen banks and replant 2500 L.F. of Lilly Run which runs behind the Havre de Grace Middle School and ultimately outfalls into the Lower Susquehanna.

Bradford Green – The Engineering and Permitting is underway to retrofit an existing stormwater management pond, enhance water quality and quantity to exceed regulation requirements, provide a wildlife habitat and stabilize approximately 290 L.F. of Lilly Run next to the pond.

City of Havre de Grace Illicit Discharge Detection and Elimination (IDDE) – This program is in full force and the City maintaining records of illicit discharges into the City storm drain system in compliance with the Clean Water Act.
