Megan,
Joel and I have reviewed the subject plan and have the following comments:
1. Provide traffic projections. Approval of road sections will be dependent on traffic data.
2. UD -4s are required for roads with ADT> 1000.
3. There should be a minimum of 1 ft of r/w behind sidewalk.
4. Pipes passing in and out of roadway should be avoided. Proposed drainage line on u -curve section on Delphi
Lane could be brought to opposite side of road or radial pipes could be used to avoid passing under pavement.
5. The use of roll top curbs is not recommended on Oval Park and Flat Waters Ln. If the use of roll top curb is
pursued, a special design entrance gutter shall be submitted for approval where roll top curb is used (VDOT
Road Design Manual F -81). A detail of the entrance transitions as well as transitions around Dls will be
necessary. Drainage calculations much show that drop inlets are spaced so that the 10 year storm
frequency does not exceed water depths of 4" at the face of curb. (Road Design Manual Appendix 131)
6. No on- street parking situations where sidewalk is placed adjacent to the back of curb require the
submission of a Design Waiver for no buffer strip (See IIM -LD -227). (Road Design Manual A -119)
Please let us know if you have any questions.
