Tc for pre- and post-development
Tc for pre- and post-development
(OP)
A site project that I am working on appears to have the pre- and post-developed time of concentration unaffected, either in time or flow path, by a proposed building location and site work. How does one address this scenario? I am worried that I will under-design the detention pond...
any thoughts are appreciated.
Thanks,
Scott

You might consider breaking out the proposed development watershed into two basins, one for the development area and one for the rest of the watershed.

What is the order of magnitude between building : drainage area?
If you are adding a 1000 sf barn on a 200-acre farm the impacts are negligible. Same barn on a 1/2 acre is a different story.
