Lets say the 90% runoff volume for the project area is 10,000 c.f. If only 50% of the project area drains to the bmp which is designed to treat 10,000 c.f. at 100% efficiency but only 7,900 c.f.

Hi, we are implementing a `Rigole´ for TSS removal. Translators dish out `french drain´ for what i would describe as a bioswale with additional storage capacity due to gravel packages or the alike.

1) Does anyone know of any local/regional programs with the 80% standard in the Vancouver, BC area?

Hello I'm very confused by the calculation methods about the TSS removal efficiency .

My understanding from the FAQ and response to the "Rainwater used for irrigation" comment is that rainwater reused on site (for sewage conveyance) is considered to meet the credit requirements.

Hi, there is a sentence in LEED Reference Guide which makes me really confused (page 103): “For existing sites with greater than 50% imperviousness, structural techniques may include restoring a

Dear LEEDers, Can someone confirm that a rainfall of 1 inch per 24 hours is 1 inch per 1 inch squared of ground surface? Thank-you, Ian
