Stormwater
Stormwater management, drainage, storage, LID and major-flow planning.
When Is On-Site Stormwater Storage Required?
On-site storage is commonly needed when runoff must be detained so discharge does not exceed an accepted rate or system capacity.
Common Stormwater Review Comments
Stormwater comments often arise when criteria, calculations and drawings do not tell one consistent, traceable design story.
What Is a Major Storm Flow Route?
A major storm flow route is the planned overland path for runoff that exceeds or bypasses the minor piped system.
Why Can’t Rainwater Normally Be Sent to the Sanitary Sewer?
Sanitary sewers are intended for wastewater, while rainfall can add large, rapid flows that consume capacity and increase overflow risk.
What Is Low Impact Development?
Low impact development uses distributed practices to manage rainfall close to where it falls.
What Is the Difference Between Drainage and Stormwater Management?
Drainage directs water safely through a site; stormwater management controls the rate, volume, quality and balance of runoff.
