Can someone tell me where to find trip generation numbers? I am doing a project and I need to find out how much traffic it will draw. The project is in NJ.
Thanks in advance.
Thanks again. I decided to use the 1 x TC to the peak and then 2 x TC back to zero, so I have a triangular hydrograph. The reviewing engineer allowed my initial assumption of just using the TC multipled by the peak flow, but an engineer was brought in as opposition. I will just have to stand...
Thanks for all your help. The engineer seems to want a triangle with a 2TC leg up and a 3TC leg down. When I do this it just seems like way to much volume, especially since I am just storing the impervious areas in seepage pits....
He is requiring the Modified Rational Method. I think doing the triangular hydrograph will probably work. Would that be using Tc to the peak, and then Tc back to zero? That would in essence be 2 x Tc. Thanks for all the responses. Steve, what part of the country are you in?
Steve, thank you for the timely response. With the site in question, I am using seepage pits to store the runoff. So I only have and outflow(overflow) for the 100 year storm. Even with the overflow, the postdeveloment runoff is less then the predevelopment. To get my volume, I used the peak...
I computed a stotage volume for a site using the rational method(Q-ciA). The site is only 2 acres. It was brought to my attention that I MUST use toe Modified Rational Method, because it will give a larger volume to be stored. What is the difference between the two? Why will it yield a much...
