Alternative Basin Designs for Small Bridge Projects and Other Environmentally Sensitive Areas (that would typically require 1.5-inch skimmers with small orifices)
Research Idea Scope
Select several of these small bridges that are being let and re-design, install and monitor the discharge from the standard skimmer basin (x2) vs. a solid dam with a weir outlet or other (x2). Basically trying to justify only using 2-inch or greater skimmers on these.
