Briarwood Phases 5 and 6 Road Plans
Phil,
We have reviewed the above referenced road plan and have the following comments:
1. Sheet 2- Typical needs to be updated to reflect the current design standards in Appendix B(1) of the VDOT Road
Design Manual. Centerline and design speeds have been revised.
2. On sheet 8, the vertical curve at station 39 must now meet a minimum K value of 26 for 25 mph design speed. The
horizontal curve must have a 200' minimum radius and the sight distance at the intersection should be 280'. The storm
sewer system from 608 to 607 should be removed from under the pavement and a structure added on Sunbird Way.
3. On sheet 9, where Jersey Pine Ridge intersects with Sunset Drive, the intersection sight distance needs to be
revised. In addition, a 50' landing must be provided on Jersey Pine Ridge and the pavement cross slope on Sunset Drive
(unless it has already been constructed) should be revised to a 2.08 %.
4. On sheet 14, the storm sewer profile should be revised to match the recommended changes shown on sheets 8 & 9.
All inlets and manholes greater than 12' in height should have a standard SL -1 safety slab shown in the structure
description.
Revise sheet 27 to reflect drainage changes.
Please let me know if you have any questions.
Thanks
Joel
