Hello everyone,

Dear all, In our project we are planning to follow option 1 path 2.

I am trying to track down historical information to meet the compliance for the pre-development pathway but am coming up short for finding land cover and contour maps predevelopment.

how to Calculate runoff volume to be managed on site giving rainfall data?

Hi,

I am evaluating the Rainwater Management of a warehouse project where the water table is very high and we don't have enough depth to make a water basin.

Hello 

Hi,

I was wondering about how to calculate the Area of bioretention needed to manage expected runoff on the Reference Guide v4 example.
