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 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...
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 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...
