WPO- 2008 -00106 Old Trail Village Phase 2 -block 4 road plans
Amy,
We have reviewed the above site plan and have the following comments:
1. The raised crosswalk on Claremont Lane needs to be removed. Traffic calming in Old Trail is
accomplished through geometrics of the roadway. The streets in Old Trail are already designed to calm
traffic through narrow typical sections, chokers at the intersections and street trees. Physical measures
such as the raised cross -walk should not be necessary and need to be removed. The northern side of
Claremont Lane should include a similar bulb out like the southern side to prevent parking and narrow
the typical at the crosswalk.
2. The sight distance for a 25 mph road is 280 feet and 30 mph is 335 feet. Sight distances at
intersections are incorrect or missing.
3. Rea's Creek Dr. and Old Trail Dr. are 30 mph designs and require a 6 foot clear zone from the face
of curb when there are no parking lanes. Street trees are not permitted within the clear zone of the street.
Also, street trees cannot be placed within 30 feet of any curb return at any intersection.
4. Sag inlets appear to have been designed under the assumption that all surface runoff will split
50150 as it flows toward the grade low points. The sump inlet comps should be reworked.
5. Some of the approach spreads have exceeded 8' from the face of curb. The only exception to this is
that 10' is allowed in areas along the parking lanes. See VDOT's Hydraulic Design Advisory HDA
08 -03 for design instructions.
6. Structures Al2 and A16 will require safety slabs.
If you have any questions, please let me know.
Thanks,
Joel
