Watershed Restoration

Also known as vegetated roofs, living roofs, or ecoroofs, green roofs are alternative roof surfaces that typically consist of waterproofing and drainage materials, along with an engineered growing media designed to support plant growth.

Open channels convey stormwater runoff and provide treatment as the water is conveyed. Runoff passes through vegetation in the channel, the subsoil matrix, and/or infiltrates the underlying soils.

Bioretention is a stormwater management practice that can achieve water quantity and quality goals through runoff reduction and pollutant removal.

Tree planting is the practice of planting deciduous or evergreen trees in areas where they will grow and create a leafy canopy that intercepts rainfall and reduces runoff.

Septic systems achieve nutrient reductions through several management practices, including routine maintenance and pumping.

A rain garden is a planted depression in the landscape designed to collect and temporarily store stormwater runoff, allowing it to be absorbed into the soil, taken up by plants, or evaporated.

Rain barrels and cisterns are collection containers placed at the end of downspouts to collect rooftop runoff and store it for later use.

Permeable pavers or porous pavement reduce runoff volume by allowing water to filter through open voids in the pavement surface to a washed gravel subsurface storage reservoir.

Downspout redirection changes the flow of rooftop stormwater so that it is no longer directed to an impervious surface or piped into a sewer system or body of water. Instead, it is directed to a pervious or permeable surface such as a yard, garden, or conservation landscape.

Conversion from Turfgrass to Conservation Landscaping is a practice that replaces sections of turfgrass with native plants.
