    Trip Generation

    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.

    Modified Rational vs. Rational Method

    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...

    Modified Rational vs. Rational Method

    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....

    Modified Rational vs. Rational Method

    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?

    Modified Rational vs. Rational Method

    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...

    Modified Rational vs. Rational Method

    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...
