1) Does anyone know of any local/regional programs with the 80% standard in the Vancouver, BC area? Our project is located in Surrey, BC.

My civil engineer tells me that he knows of no local/regional stormwater programs that have adopted the 80% TSS removal standard. Therefore, we need to provide field measurements after the installation.

2) Does anyone know of any good tools to estimate stormwater TSS removal? We have mostly non-structural measures (a lot of green roofs). It would be very helpful to know if we're getting close to this point.

Thanks!
