Tree Planting

Residential tree plantings enhance the natural beauty of the area, protect watersheds, and provide habitat. The larger the area planted the greater the benefit to the environment.

Conversion from impervious to turf/conservation landscaping

Conversion from impervious to turf/conservation landscaping is a practice that replaces sections of turf grass with native plantings. These plantings provide greater water infiltration and habitat and require less water and fertilizers compared to turf grass.

Riparian Buffer Plantings

Buffer strips running parallel to a waterway and are vegetated areas of land that contains a variety of trees, shrubs and native grasses.

Certified Baywise Landscape

Bay-Wise Landscaping is a free certification program offered by the University of Maryland Extension that recognizes homeowners for their Bay-Friendly landscaping practices. Homeowners can receive a sign for their certified property.

Permeable Pavers

Porous pavement or pavers that reduce runoff volume and treat water quality through both infiltration and filtration mechanisms. Water filters through open voids in the pavement surface to a washed gravel subsurface storage reservoir, where it is then slowly infiltrated into the underlying soils or...

Bioswales and Vegetated Open Channels

Open channel that conveys stormwater runoff and provides treatment as the water is conveyed. Runoff passes through either vegetation in the channel, subsoil matrix, and/or is infiltrated into the underlying soils. In their simplest forms, bioswales are long, linear infiltration systems that receive...


A large excavated pit backfilled with engineered media, topsoil, mulch, and vegetation. These are planting areas installed in shallow basins in which the stormwater runoff is temporarily ponded and then treated by filtering through the bed components, and through biological and biochemical...

Infiltration Trench or Basin

An infiltration trench or basin is a long, narrow, rock-filled trench or depression where sediment is trapped and water infiltrates the soil. No underdrains are associated with infiltration basins and trenches, because by definition these systems provide complete infiltration. These systems are...

Downspout Disconnect

Downspout disconnection is the process of separating roof downspouts from the sewer/stormwater system and/or redirecting downspouts from impervious surfaces that drain to sewer/stormwater system onto pervious surfaces (most commonly rain gardens and rain barrels).

Watershed Restoration Assistance Directory

The Maryland Watershed Restoration Assistance Directory offers one-stop shopping for anyone interested in finding funds or technical assistance to implement projects that restore Maryland's streams, rivers, bays, and watersheds. Included are programs offered by a wide range of entities, including...
