Does anyone know where I can find a concrete overflow structure (weir) detail for a retention pond? The local municipality is looking for something more permanent than a "grass"-type weir. My weir opening length is about 50' wide and top of bank is about 1.2' above bottom of weir elevation...

What type of structures do you typically use when connecting large storm sewer pipes (i.e. 96" diameter RCP). I'm not sure if they make manholes in that large of a diameter, would you use a Tee with riser?
