RE: UVA Research Park Loop Road — Road Plan Review — SUB-2019-00049 - Comment
Response Letter
We have reviewed all of your comments from May 21, 2019 and made the necessary revisions.
Please find our responses to the comments below in bold lettering.
1. A marked crosswalk does not appear to be warranted at the Lewis & Clark Drive
entrance and should be removed. The Department will not maintain unwarranted
marked crosswalks.
The crosswalk at the Lewis and Clark Drive entrance has been removed.
2. CG-12 at the entrance should be angled perpendicular to the crossing street, not at 45
degrees as proposed.
In response to comment # 2 of the Road Plan review regarding the CG-12 ramps at the
intersection of Loop Road and Innovation drive being at a skew, we believe that the
current design is in compliances with ADA "Advisory 405.7 Landings" and ADA
"Advisory 406.6 Diagonal Curb Ramps". Landings should be perpendicular to the path
of travel to allow for more acceptable cross slopes for ADA access. The ramp must
come down perpendicular to the gutter pan/ flow line so that the pedestrian does not
need to traverse the slope of the gutter at an angle. Providing a landing before the
gutter pan would require the ADA ramps to extend back to the north and South as
much as 10' which would make it difficult to tie the current and future sidewalk from
the west into the top of the ramp.
3. It is assumed that the proposed street is intended to be private; please clearly indicate
this on plans.
The proposed street is private and has now been labeled accordingly.
