We are doing a project for the levee system here is California. It involves a ramp / walk way that goes down the side of the levee to a boat ramp. Sucker is a good 240 FEET LONG (as the crow flies) with "level" places every so many feet per ADA rules. Plus multiple elevation and angle changes every few feet. Nothing straight for good length. Our fabrication supervisor says we can round the angles to half a degree. Uh don't know how to do that. Angles are decimal, ie 90.35, 81.76.
