Keith,
A few more things:
1. Your typical driveway section shows the driveway approach rising 6 inches from the gutter to the
edge of the sidewalk crossing. On the east side of Coppell Road this distance is 4.5 feet resulting in an
11.11% grade. Do you want to build the driveways this way or do you have a maximum percent grade
you would like to use for this section of the driveway? We are getting ready to look at the cross-
sections at all the driveways and streets to revise them for ADA concerns. I have attached a PDF of
your detail for your reference. Let me know.
2. As far as grading between the sidewalks and right-of-way lines there are several options. One is to
grade out like the current cross-sections show on private property. You would then need an easement or
letter of permission to do this grading. try grading out between the sidewalk and right-of-way line and
stay off of private property. This would result in steep slopes within the right-of-way. or a third option
would be to construct sidewalk curbs and use flatter slopes to grade out in the right-of-way. Let me
know what you prefer and we will take a look at it.
3. You made reference in your review to temporary shoring similar to the East Sandy Lake Road
project. Do you have a copy of the plans that you can send us or we can pick up illustrating what you
are talking about?
Thanks for your help,
