reflected differently on other submittals.
3. [General]
4. [4.12.16c1] Perpendicular parking must be 9'x 18' or 10'x 18', some spaces
appear to be 9'x 16'.
5. [General] Retaining walls adjacent to residential areas appear to be on or over
the property lines. How will these be constructed without getting onto adjacent
property? See engineering comments.

Re: Stonefield Blocks F & G Final Site Plan
Dear Ms. Baldwin:
We have reviewed the final site plan for Stonefield Blocks F & G dated 11/7/13 as submitted by
W W Associates and offer the following comments:
1. The dimensions of the left turn lane and taper off of 4th Street should be shown on the site
plan. In addition, left turn lane warrants should be provided.
2. I have concerns that the left turn queue off of 4th Street may create a problem with the
intersection of 4th Street and Rte. 29 due to volume of traffic travelling east on 4th Street
towards Rte. 29. If it cannot be demonstrated that this left turn movement will function
without adverse impact to the Rte. 29 intersection, the proposed entrance should either be
removed or made right- in/right -out by extending the median.
3. Is the intention to close the 4th Street connection to Rte. 29 at any point during
construction? If so, the timing and operation of the traffic signal at the intersection needs
to be considered and evaluated.
4. The construction entrance shown on 4th Street should be removed due to safety concerns.
The construction entrance off of District Avenue should be adequate for this project.
If you need additional information concerning this project, please feel free to contact me.
Sincerely,
U�

A. Site Development Plan (SDP201300061)
1. Please measure parking stall from face of curb to end of parking stall to avoid any confusion. For
example some are labeled 9'x18' and some are 9'x16' (from edge of gutter to end of stall).
2. On sheet C -8 shift both stop signs 4' from the edge of intersecting travelway. These stop signs are
located at exits of parking areas.
3. There is a crosswalk across Inglewood Drive. A CG -12 will be needed to tie into crosswalk. I will
defer to planning to decide who is required to build that CG -12. Please discuss with planning.
4. Will there be a future sidewalk on the other side of District Ave? If a crosswalk across Blackbird
Lane is necessary, this may impact the pavement marking at intersection. A 4' gap is standard
between a crosswalk and white bar shown.
5. Sidewalks are typically shown on both sides of street. Is there a waiver to show sidewalk on one
side of the street for Blackbird Lane and Swanson Drive Extended? Please clarify.
6. For Blackbird Lane, Swanson Drive Extended and 01 St, all entrances from travelway shall show a
'25' radius at a minimum. See VDOT standard on page F -103. The link is shown below.
littp://www.extraiiet.vdot.state.va.us/loedes/Electronic Pubs /2005 %20RDM /AppendF.pdf
7. Show a solid yellow line around median in NE corner of fuel area.
8. What are circular items on fuel area near island? Are they bollards?
9. Please provide'a circulation path for heaviest vehicle (ie. fuel trucks and 18 wheelers to bldg F -1)
to ensure radius of medians are adequate.
10. On sheet C -10, the entrance to Block G from 4`'' St has not been approved by the County Engineer.
The additional traffic study has not been presented nor has it been approved by the County
Engineer. Please show the median with no breaks.
11. It appears some comments from the ZMA have not been addressed and should be addressed during
the site plan phase. Please. address the following:
Engineering Review Comments
Page 2 of 3
a) The intersection of Swanson Drive Extended and 4th St. is almost addressed. The median on
4'h St needs to be widened to about 4' and revised to a raised median for its entire length. The
pavement striping will not work. This raised median will be a pedestrian refuge if future
sidewalks are necessary.
b) Please provide a minimum radius of 3' for the median allowing channelized flow from
Swanson Drive Extended.
c) There is still an abrupt taper passed the intersection of Swanson Drive Extended and 4 " St.
This area is almost addressed. Please use VDOT taper standard 8:1.
hqp://www.extraliet.vdot.state.va.us/locdes/Electronic Pubs /2005 %20RDM /AppendF.pdf
d) Extend island around fuel area to 4th St.
e) On the SE comer of Bldg F -1, the pavement tapers off again. Please use VDOT taper standard
8:1. A smoother transition shall be shown for future connection to work. Also, maintain the
30' travelway around bldg corner.
f) On NE side of bldg there are concrete slabs. The travelway needs to be clearly conveyed along
this area. I recommend providing pavement marking for travelway.
g) The applicant has agreed to reserve a possible parking entrance at the intersection of Blackbird
Lane and District Ave. Please place a note on plan noting the entrance will be opened if left
turn lane queuing length to proposed F -1 Bldg entrance is deemed inadequate by the County
Engineer. I recommend including an inset within sheet showing this entrance. Also, please
show easement for this entrance on plan.
12. Please show and label all the future connections on plan. Include the connector road to
Commonwealth since it has been proffered.
13. Please show easements on plan for private road. This will need to be recorded on a plat. Also note,
that stub outs for future connections shall be shown with easements. The easement should be wide
enough for required grading to build future connection.
14. Please revise dimension for entrance near the vortechs. It appears greater than 24'..
15. The parking stall near the vortechs area needs to be 9'x18'. Please revise stall and revise
dimensions for the 9'x17.5' and 9'x 18.5'.
16. Please clarify why additional parking is proposed near the vortechs area. It appears this will be for
future retail building within Block G.
17. The entrance from Blackbird Lane to Block F (near Inglewood Drive) is about 8 %. Maximum
entrance slope is 4 %. Please revise.
18. Please provide 1' contours on site due to topography of site. Also, clearly label high points on site.
19. Provide detail for 225.1. There should be a depression to filterra inlet for maximum capture.
Otherwise, runoff will just spill over to structure 225.

20. Provide another filterra east of structure 226 to treat eastern side of that parking area. Also,
provide at a minimum .5% grade for parking along bldg's NW wall for positive grade to additional
filterra mentioned.
21. As a general comment, please show a minimum .5% grade on site.
22. All street name signs shall be located on the left side of road per Albemarle County Design
Standards.
23. East of the loading dock wall are 478 contours. This area appears to be a ponding area. Please
address grading to divert runoff to an inlet.
24. It appears there is more capture to DI structure 222 than filterra structure 222.1. Please revise
layout for more treatment.
25. Provide an island for parking located west of loading dock entrance.
26. Some areas for proposed retaining walls are near the property line. For example in the NW corner,
the retaining walls are about 12' high. It appears that land disturbance will be over the property
line to construct walls. I recommend obtaining a grading easement from adjacent property owner.
It appears there is another retaining wall right at the property line on the western property
boundary line. Please clarify for all retaining walls near property line.
27. There are two areas on Sheet C -11 and C -12 that shows the sidewalk tapering from 6' to 5'.1 do
not see the need to taper as majority of sidewalk is 6'. Please revise.
28. Please revise the spot elevations for the entrance to bldg F -1 from Blackbird Lane. The topo is not
clear if it is a positive slope or negative slope. It appears the island towards the underground pipes
can be lowered so runoff can be conveyed to parking lot inlet instead of Blackbird Lane.
29. On southern end of parking lot, there is a spot elevation 72.01 (TC) that will act as a low spot.
Please revise so runoff can drain to structure 206.1.
30. For crosswalk across Swanson Drive Extended and continues to Bldg F -1, I recommend shifting
about 3' north to be in alignment with sidewalk running east. This will also allow pavement
marking near crosswalk to shift closer to intersection.
31. Please provide 20' easements for all SWM facilities and stormsewer pipes.
Sincerely,
Michelle Roberge
