British Columbia Moves Beyond 90% Rainfall Capture Target Proposed by United States EPA

Rainwater Management is About Protecting Streams, Not How Much Volume is Infiltrated

In April 2010, the United States EPA announced performance standards requiring 90 percent on-site retention of rainwater runoff from new development in Washington, DC.
“While that target may achieve a reduction in the potential pollutant load to a stream by 90%, additional benefits can be achieved if we follow the progression of scientific learning to the next logical step,” states Jim Dumont, Engineering Applications Authority for the British Columbia Inter-Governmental Partnership.
