Re: SUB - 2014 -001 10 Whittington, Phase B Preliminary Subdivision Plat
Dear Ms. Ray.
We have reviewed the preliminary subdivision plat for Whittington Subdivision, Phase B dated 7714 as submitted
by Dominion Engineering and offer the following comments.
L Proposed pavement design will need to be verified by pavement design calculations that will need to be
submitted with the road plan.
2. Justification for the reduction of the minimum pavement width of 24' to 20' should be added to the typical
section for streets "A ", "B ", and "C ". In addition, the typical section for these streets should be noted as
"No Parking" on the streets.
3. The typical section for Kendra Street should be noted as "No Parking ".
4. Sheet number 6 of 14 shows storm sewer located within the roadside ditches. What is the purpose of
including storm sewer in these areas?
5. On sheet number I I of 14, is the terminus of Kendra Street shown proposed to be a temporary or
permanent turnaround? The preferred turnaround at this location would be a cul -de -sac. The "branch -
type" turnaround shown does not appear to have an adequate length or radii.
6. Per Appendix B(1) of the Road Design Manual, cul -de -sacs with unpaved centers should be considered
one -away and designed in accordance with Table 3 of Appendix B(I ). Refer to page B(1) -24 of the Road
Design Manual.
7. On sheet 13 of 14, Route 631 does not appear to be drawn accurately based on the contours provided. The
edge of pavement of Route 631 should be field verified and reflected on the preliminary plat.
8. I question the availability of adequate intersection sight distance at the intersection of street "C" and Route
631. Sight lines should be provided at each intersection, and sight line profiles should be provided at
locations with questionable sight distance such as the intersection of street "C" and Route 631. For 45
mph, the minimum intersection sight distance required is 500 feet.
9. The alignments and locations of the proposed streets may need to be adjusted as the road plans are prepared
and reviewed.
If you need additional information concerning this project, please do not hesitate to contact me at (434) 422 -9782.
