    Detention Pond Question

    Jeffcivil2, Not to pander on, but you said: "a 4" orifice I can guarantee you even at a 50' depth below the HWE isn't going to carry a 100 year storm.. It will only carry roughly 3.5 cfs, which is considerably less than the 100 year flow from a 1 acre impervious site ( IN Atlanta that would...

    Detention Pond Question

    Thanks Jeffcivil2, but as CVG pointed out, this is detention as opposed to retention. Based on new requirements in the Charlotte, NC area (Hi, neighbour)we are required to retain the 1st inch of runoff for 24-72 hrs. However, this site is grandfathered. Also, I should apologize - I should have...

    Delayed Paving Drainage Problems

    I also have these similar problems. We are required to do the final 1" overlay of the asphalt at project completion. I find that the majority of the problems are due to bypass from the upstream catch basins or a road that is proposed to be built in a future phase uphill, which would collect...

    Detention Pond Question

    Just to clarify, In my previous post I should have said -we are required to retain the runoff from the 1st inch of rainfall.

    Detention Pond Question

    Thanks CVG, In this case it is detention. In this area we have policies in the works where you are required to retain the first inch of runoff, above that detention is required.

    Detention Pond Question

    We are designing an industrial site where detention is required up to the 100 year storm. The rear of the site is a loading dock. We are allowed to pond water in the loading dock area up to 18", and are thinking of using this as the detention pond. When I model the pond using a 4" orifice 1'...

    Shallow Ford Stream Crossing

    CarlB, After taking a closer look at it, and doing some more reading, I think you are right. We are going back to the original thought utilizing stone. We have done some velocity calculations just assuming bank full and it is somewhere in the range of 3 fps. I think the stone is a reasonable...

    Shallow Ford Stream Crossing

    Thank you for your responses, The stream we are crossing is in a FEMA regulated floodplain and drains a fairly large area. When I said low flow, that probably was not the correct term. Any time it rains the crossing will be impassable. There is rock roughly 4-5' below the streambed. Based on...

    Shallow Ford Stream Crossing

    Hi, Could anyone recommend a reference (or any ideas) for a shallow ford (low flow)stream crossing for a walking trail - concrete or otherwise? I have seen a couple of NRCS details which utilize small stone held in place by large boulders down stream, but I don't feel that these will be...

    WaterCad - Inputting Hydrant Flows?

    Sorry - weight of water = 62.4 lb/ft^3

    WaterCad - Inputting Hydrant Flows?

    Again correct me if I am wrong but I think you can convert the psi to feet of head using the weight of water (62.4 lb/ft^2). The terms static and residual both refer to static pressure. The equation I mentioned is a form of the Hazen Williams equation(I think, my weekend brain is garbled as...

    Network Plotter/Printer Question

    Thanks Mike, That's exactly why I was asking this question. The plotter was physically connected to the server previously and shared to the other computers. We had the network card installed. The plotter was connected to the network, and set up as local printer on the server and again shared to...

    Network Plotter/Printer Question

    Hi, We recently had a network card installed on our OCE plotter. We have a small network with a server. The plotter is connected to the network via a "lpr" port and is a local printer on the server. The plotter is shared on the server and the other computers connect to it through the server as a...
