Hi everyone.

Hi,

Just want to clarify the exact meaning of the existing impervious and it's calculation. Below are my questions:

I am working on Core & Shell Office Building Bangladesh where my Site Area is 4434.71 square feet.

Is it acceptable to utilize an existing detention pond that is outside the proposed LEED boundary? The stormwater runoff will be piped under the existing road to the pond.

Our project has a big rainwater collecting tank which has enough capacity to store 2-24hr design storm, but the tank doesn't have function of infiltration and all the stored rainwater will be pumpe

Hi, We are working in project previously land was empty top soil is hard and when calculating Pre-development

I have a LEED project where they plan a storm water tank that will be a shared one with two other buildings next to the LEED project building.

Hi! I'm having some difficulties with the calculations, specially with the meaning of each variable in each equation. In equation 1, the 'P' (average rainfall event), should we consider the year

Our project is located in a city with a very low annual rainfall average (8.3mm that is about 0.327 inches per year). The project will have a green roof in about 60% of the roof area.

SS C6.1 has two cases: Case 1: Sites with existing imperviousness 50% or less: Requires proposed runoff not exceeding the existing runoff. Case 2: Sites with existing imperviousness greater than 50
