RFI 12 1 wanted to get your input on the revised Knight's Way driveway. I've attached a sketch showing a different curb ramp configuration. The only concern I have is the sidewalk leading to the "tower ". I'm showing an elevation of approximately 8.6 %. It would require two steps to eliminate the steep grade. Call me once you've had a chance to review it the attached sketch. Pajares Screening Wall I've attached an alternate detail for a traffic rail that could have a stone face affixed to the back. There is no issue attaching stone facing to the back of it. B. Caleb Thornhill P.E. Project Manager Freese and Nichols.
