To counter act the forces from the 90 degree turn you are going to need thrust blocking or wingwalls to keep this structure from moving. The structure could not be tied to the existing wall, unless the structural engineer would approve it. Thrust blocking would have to be installed opposite...
If it is not in "Design of Small Canal Structures" US Department of Interior-Bureau of Reclamation 1974, I don't know where it would be.
I am unsure how there could be lift, if not from beneath the structure. I do not see a way for water to transmit tension forces on the concrete to lift it...
Armor the natural swale (rip rap) that has formed down to the bottom of the gulley and divert all stormwater to the swale. Use some temporary erosion control matting and seeding to stabilize the existing bank. Install a gutter system and downspout that discharges to the amored swale. Then...
Isn't there an easement on his property for this culvert? If so you don't need his permission to enter and bring equipment into the easement area. Have someone pull up the title to look for the storm easement. If an easement exists, have title with you when you inspect show it to the owner...
US Bureau of Reclamation Type VI Dissipator- been around awhile and they are still using it. Good for up to 50 fps and 400 cfs.
I bet a Type VI structure would end up costing less than a 25' deep 7' dia. MH because of the cost of the very deep excavation through the slope for the pipe to get 5%...
I went through the BOR Design of Small Canal Structures (1987) and I will be using a Type IX baffled apron drop chute as an inlet structure to the bottom of a small reservoir with a HDPE liner. I have all the needed dimensions but don't want to have to start from scratch on the CAD detail...
Thanks for the replies.
To answer some of these great questions, this is an at will company so there is no contract even for full time employees. The intent was to get my benefits back, if not I will leave. I am being partially compensated for them, by hourly, but this was supposed to a...
The contract does not list it as a requirement, it is only a letter from HR with "condolences for terminating my employment" and basically telling me what they are stripping of and what to do with 401K, etc. I am most pissed that they illegally (in my opinion) took flex spending account...
Is it a required professional courtesy to give two weeks notice if you have been reduced to an on call status? Technically I am not an employee anymore but a contract worker. I looking to see if this is the professional standard for our field for a contract worker or more just a "courtesy"
I...
Lumnite MG is a cement highly resistant to chemicals and acids. Haven't used the product myself, but have been researching it. There is good info on their website.

I think you provided the wrong link. The link you provided was for probalistic future flows based on data from 5/9/11, it is not recorded stage/discharge flows.
I agree with Beej67, if he wants it his way he stamps it. Just mention what code you are using when you hand it to him for his review, so it doesn't look like you are trying to sneak one by him. If he doesn't want to you the most current code you can refuse to stamp it on basis of Engineering...
I'd walk the section during a brisk rainfall. All the existing drainage problems and potential drainage problems from the 2" overlay will be come real apparent during a rain storm. This gives you a good chance to identify any bird baths and any existing catchbasins inlets that are not placed...
You will have to treat the stormwater before the natural wetland, and cannot use a natural wetland for treatment. You can design a treatment wetland but it would have to outlet to the buffer of the native wetland.
Over here (Washington) you could get full dispersion and WQ treatment credit...
You could retrofit to a M Road Section /\/\ by removing the existing 40' center section out amd regrading the center lanes section to 2% as a valley (keeping the outermost and inner most existing lanes intact and sloped toward the curb). This would allow you to keep one lane functional in each...
