Let It Rain.

 
Rainy days happen...so what do you do with the water?
 
Currently stormwater quality requirements can cause serious impacts to site planning efforts.  Our engineers and landscape architects, however, can often prescribe a variety of creative stormwater treatment applications to meet these strict agency requirements.  Here are a few tips to ensure optimal results.

 

Vegetated Swales

A shallow, open-channel drainage way, with plantings to control flow velocity and depth to promote settling and filtration of the sediments in the runoff flowing through it.

  • Best to locate away from buildings and foundations
  • Typical locations are edges of parking lots or long, linear planter islands
  • Best suited for areas with relatively flat or mild slopes
  • A minimum planter width of 10 feet is preferred
  • Swale length varies greatly.  An acre drainage area typically requires 75-100 LF while a 1/2 acre requires 50-75 LF

Stormwater Planters / Rain Gardens

A depressed vegetated planter area containing a special soil mixture that allows for minimal surface detention and treatment of runoff as it infiltrates into the underlying soils.

  • Locate away from buildings and foundations where possible
  • Best suited for relatively flat areas
  • Footprint shape can vary, but a minimum width of 10 feet is preferred
  • Footprint area approximately equal to 4 - 5% of the drainage shed area
