5 Things to Love About Low Impact Development

Did you know that Low Impact Development (LID) can work to the advantage of a developer when it comes to stormwater permitting?  And as we talked about in a previous blog – it CAN COST LESS!

If you’re not familiar with the term, let’s get up to speed. LID is an overall site design approach that aims to mimic natural site hydrology through the use of natural best management practices for stormwater management. One LID technique our landscape architects and stormwater experts like to implement is bioretention.

Biorentention uses the natural biological and physical characteristics of soil and vegetation to capture, store and filter stormwater runoff. Vegetation, such as trees, shrubs, and grasses remove pollutants that are picked up in stormwater as it flows over ground surfaces through uptake by their root systems.  Soil particles trap the pollutants through absorption while the water filters through. 

What do we love about these systems?

1. They are aesthetically pleasing. 

2. Provide stormwater rate and volume control as well as water quality benefits which aides in meeting stormwater/NPDES permitting criteria.

3. “Flexible” – Can easily be incorporated into green spaces, streetscapes, median strips and parking lot islands.

4. They are efficient and cost-effective.

5. Great for the environment and wildlife. They create habitats, provide shade, reduce urban heat island effect and improve air quality.

Look for upcoming blogs as we talk about the different types of bioretention systems including rain gardens, infiltration basins and vegetated swales that can be used for stormwater management.
