By any chance is anyone proficient with the EPA's guidelines for NPDES? I need to provide an erosion control plan for a 3 acre project site. I will include the usual silt fence around the property and tracking device at the entrance. However, we are going for a LEED certification, and need to...
Another basic item I don't know about. How do you properly design/size a catch basin? For example, if you are receiving say 1000 gpm, do you chose a bsin which can hold 1000 gal.? May sound like a dumb question, most people I know have just sized on gut feeling, no particular reference.

I ran the HGL from the tailwater downstream and sized the pipes such that the HGL happens to be 1.3' below the top of my grate in the garage. As you mentioned, I definitely want to allow for the freeboard. Is there a way of quantifying how much the water will rise in this basin due to the high...
I am working on a drainage system for a 3 acre site in Florida. All of the catch basins are interconnected and empty out into a control structure and eventually a canal. However, one the CB furthest upstream is located at the lowest point of a 3 story parking garage. I've run my hydraulic grade...
I am trying to help a friend out with his 2-story barn structure which consists/upported by braced frames in one direction. The braced frame problem I have consists of a 6x12 DF-L No.1 girder, supported by a post on each side, and the girder is further supported by 6x6 knee-braces connecting the...
Thank you. I have used RISA 2-D before in school and it is quite easy to use, so that may be my best option
Was curious if there were other programs out there that have the NDS check built in as well.
Any recommendations on structural analyis software that checks the latest NDS wood codes (or at least the 2001 NDS)? The design example I am doing consists of two (2) posts supporting a beam, with additional support from knee-braces connecting the beam and posts at both ends. Already calcualted...
I am new to structural engineering and have been assigned to design a barn structure. Is there literature or design examples on using metal roofing to calcualte roof diaphragm forces, etc.? The metal roofing will be screwed to 2x6 purlins @ 24" o.c. (lying on weak axis) against tied rafters. The...
I need some tips on how to design a parking lot. First, this particular parking lot will be constructed over the existing, which is currently too low (sinking into wetland area. I am planning on adding 3' of lightweight fill on top of the existing to protect it obviously from high tide...
Thank you for the replies to my question. It seems there is no avoiding going through all of the utility companies and local governments to retrieve data. Last chance may be a local mapping company that may have GIS data...which would be ideal.
Thank you
I currently began a new project along 3 miles of a creek in San Jose, Ca. Finding the existing utility is the only thing I am lacking at the moment in order to get started. It would be ideal if someone had it available on autocad or microstation files, and in layers for different utilities...
I recently began work on design a 2 mile long trapezoidal channel, for flood protection. From Hydraulics, I recieved my cross sections (HEC-RAS), and I'm ready to begin the design surface for my channel. Using InRoads software, I am able to create typical sections, which therefore will creat my...
