I wanted to see if anybody knows of any classes that go over floodplain delineation and/or doing the LOMR or CLOMR applications. I've been looking around and haven't seen too much. I would be able to go just about anywhere in the continental US if the class is good enough to warrant it...
Just wondered if anybody has used the dewatering bags that you can pump sediment laden water into and it filters it out and allows the clean water to pass through. I have not had to use them yet and wanted to know how effective they are, how much water can be passed through them before they...
Working on a project where we have limited depth to the point where storm sewers lack typical cover and are even not fitting into catch basin structures. The client wants to have a retention basin as an aesthetic feature on site. One way to remedy the storm sewer elevations would be to lower...
Is there any research out there about using moss as a ground cover for a swale. Generally if you're in a shady, moist location and you have an acidic soil you can establish moss growth. Just wasn't sure if it has the ability to hold up to slow or moderate running water and what kind of root...
Can a sanitary sewer be directionally bored under truck docks with the end result being a gravity sanitary sewer line? Pipe size would need to be 6" or 8". Length of the bore/pipe would end up being about 700 feet. I am trying to avoid tearing up trucks by installing an open cut sanitary...
Seems like most projects I design end up with a small orifice to meter the water quality volume. I need to find some alternatives for these small orifices. 95% of our projects are designed with an extended-dry detention basin for stormwater management. Therefore, a reverse flow pipe isn't an...
Have a project where we will have a small amount of underground storage serving as part of our detention system. It will be 5 runs of 18" diameter pipe (double wall w/ corrugated exterior and smooth interior) and each run is 200 feet long. Looking at the how the manifolds were constructed...
Have a project where they want to loop the water line from one street with a 12" line to a cul-de-sac with a 1o" line. The proposed water line will be 12". When tapping to the existing 12" line, is it easier/better to use a tapping sleeve and valve or shut the line down and install a 12"x12" tee?
I have a retention basin that I would like to construct in a C/D type soil. The depth to water table is shown to be at a range of 12 to 30 inches below grade. The soils info a have also says that the Capacity of the most limiting layer to transmit water is Moderately low to Moderately high...
I have a client who is interested in using asphalt grindings as the base course material for a new asphalt paved parking lot. Lot size is a little over an acre. Wondering if anybody has done this before. My concerns are getting it compacted well enough and it's longevity/durability. Should...

I have some questions based on the responses within the referenced thread, particularly when dealing with sites of 5 acres or less. I have been using the Rational Method to calc my storage volumes much in the same way you calc a water quality volume. In Ohio water quality...
