Hi - I'm working on a very small site, where it appears our only method of storm water quality treatment will be underground, via a box like the ADS Baysaver or VortSentry. However, both of this are way over sized for my flow of 0.05 cfs! Do you know of anything else on the market that is an...
I'm doing some work for a non-profit's new 900 square foot building. The foundation is a thickened slab. In our typical commercial work, I would always call out for a foundation drain around the perimeter of the thickened floor edge. However, is it really necessary for such a small structure...
Hi -
I'm looking for some guidance on how to calculate the peak daily sewage flow leaving my building for purposes of comparing that to our permitted DEQ capacity (septic system). This seems like such a simple procedure, yet I can't find a metholology in any of my references! I'm looking in...

I have been looking to hold a maximum cross-slope and forward slope of 5%, which results in a net slope...
I am designing a loading area for a commercial site where all deliveries are by post (FedEx, UPS, etc.)
- No frieght vehicles -
The drive aisle to the loading area "dead ends". I'm trying to determine what the minimum width needs to be for these vehicles to turnaround, with one back-up...
Is anyone familiar with the use of automatically opening "flow-thru" garage doors in floodways and floodplains?
This has become a relatively common practice in our area. Yet recently, a higher-up at FEMA told my colleage that these are not acceptable, that any openings required for flood...
I am looking for direction on finding trip-generation rates for a new homeless shelter for men. This is in regard to a "Gospel Rescue Mission" project I am involved in. The data will be used at the City for calculating system development charges for transportation. (A traffic study was not...
In my business, I have been in a position where I am increasingly aware of unlicensed practice of engineering or architecture. My question is at what point is it unethical to NOT report unlicensed practice:
