What Is Low-Impact Development?

5 Benefits of Low-Impact Development Explained

If you are developing a commercial property and are considering stormwater solutions to control runoff, you may wonder what low-impact development is. In short, it is a system that mimics the natural hydrology of the property to manage rainfall at the source rather than allowing runoff to affect other properties in the area. It is an effective strategy to minimize runoff and erosion while preventing pollution from impermeable surfaces like parking lots and roadways. There are five basic principles of low-impact development.

Conserve Natural Areas

Paving over the entirety of a commercial property will create one massive surface to catch rain and create undesirable runoff. To keep runoff to a minimum, maintain as many green areas as possible. Established native plants and soil can go a long way toward controlling rainwater and minimizing runoff. Plus, you will reduce the harmful effects of runoff and make your commercial property look more attractive and natural.

Minimize Impact on Hydrology

Using appropriate techniques to minimize the development’s effects on the natural hydrology of the property can significantly reduce runoff and its damaging effects like pollution. This can mean everything from maintaining natural areas to avoiding significant changes to the grade and using permeable surfaces whenever possible rather than asphalt or concrete — mimicking the natural hydrology as closely as possible will allow rain to soak into the soil or evaporate.

Maintain Runoff Rate & Duration

Ideally, rainwater should never leave the property. Runoff rates and duration after the development is complete should match those of the undeveloped property. A combination of retention and control features should allow you to minimize the water that leaves the property as runoff. This will reduce your impact on neighboring properties and the municipal stormwater system.

Implement Integrated Management Practices

Integrated Management Practices are your property’s built-in features that help you manage runoff. They include systems that infiltrate rainwater into the soil, retain runoff, store it, or aid in its evaporation. Some IMPS examples include swales or small ridges that direct rainwater to certain areas, rain gardens that keep runoff with plants and soil, green roofs that absorb rainwater, or pervious concrete that allows moisture to soak through into the earth below. All of these reduce the amount of rainwater that turns into runoff.

Pollution Prevention, Maintenance, & Public Education

Runoff from solid surfaces like parking lots or sidewalks can often contain trash, debris, and pollutants like fuel or oil. Capturing and treating runoff from these areas is essential to protect the environment. Systems like hydrodynamic separators can pull large debris and sediment from the runoff. At the same time, retention, filtering, and treatment facilities can filter the water and remove pollutants like oil, heavy metals, or chemicals. Routine maintenance is essential to keep these systems operating correctly, as is public education to help prevent pollution and keep debris out of the stormwater system. Preventing pollution can keep help to protect groundwater resources, as well as natural habitats for animals, birds, and fish.

Real Results

iStormwater LLC was an excellent choice. They made the process of the Storm water pond repairs seamless. They took charge of the project and got the project approved and passing the inspection. We highly recommend them and would use them again.

Lyonswood HOA

Incredible stormwater management service. The owner John consulted on a property I manage and ended up saving us thousands of dollars in environmental fees from the government. Now, our property is compliant with the EPA and we have a great partner to keep us maintained on storm water regulations over time.
