Stormwater runoff is the leading source of water pollution in urban areas. Stormwater is rain or snowmelt that runs off hard (impervious) surfaces such as parking lots, roads, and roofs. Pollutants are picked up by stormwater which then flows untreated to the nearest waterway and eventually the French Broad River. Common pollutants in stormwater include trash, oil & gas, lawn fertilizer, pesticides, and bacteria. Impervious surfaces also prevent rain or snowmelt from soaking into the ground and recharging our groundwater supply.
Did you know that 650 gallons of water runs off an average sized home’s roof during a 1” rain?
All this collective stormwater can becomes quite a powerful force. The energy behind this large amount of stormwater scours streambanks leading to erosion, property loss and sediment pollution.
Increasing development in Western North Carolina has led to an increase in impervious surfaces and stormwater runoff within the French Broad River watershed. In order to protect our water quality, communities must pursue low impact development (LID), which puts an emphasis on green infrastructure (GI). GI works with nature to manage stormwater as close to its source as possible. The goal is to keep it on site, slow it down, and let it soak in. As stormwater soaks into the soil, microbes break down pollutants while native plants absorb water, removing any excess nitrogen and phosphorus.
RiverLink’s Watershed Resources Program pursues grant funding to install green infrastructure known as stormwater control measures (SCMs), which capture, store, and filter stormwater runoff before it enters our waterways. SCMs include rain gardens, bioretention cells, and wetlands. In addition to protecting water quality, SCMs can be beautiful additions to the landscape and provide important habitat for wildlife.
Givens Estates is a non-profit Methodist retirement community on Sweeten Creek Rd. in South Asheville with a strong ethic of environmental stewardship. Their campus contains steep slopes and two tributaries of Dingle Creek. Clean Water Management Trust Fund has awarded RiverLink funding to install stormwater control measures on Givens Estates to mitigate runoff from impervious surfaces on campus. Read More
The Craven Street Improvement Project was a public infrastructure project that occurred in conjunction with the City of Asheville, RiverLink, and New Belgium Brewing Company. The project included realignment of Craven Street, improved pedestrian transportation, stormwater management and water quality improvement in Penland Creek that bisects the New Belgium property.

The Southside Community Stormwater Project is an opportunity to address water quality issues and the needs of a marginalized community. RiverLink is partnering with the Asheville Housing Authority to construct stormwater features that capture and filter runoff before it reaches Nasty Branch and the French Broad River and provide community amenities at Erskine Apartmen Read More
