A. Site Development Plan (SDP201300002)
1. It appears the shape of the biofilter NW of site has slightly changed. Please differentiate between the
existing and the revised easements. This will need to be updated on plats. Also, call out the proposed
stormsewer easements on the grading plan.
2. Please increase the 18' travelway to 20' (west of the building). 20' is the minimum travelway width for
two -way access aisles. Section 4.12.17
3. The travelway NE of parking lot transitions from a 30' to 20'. The minimum travelway is 24' for lots
with 9'xl8'parking spaces per Section 4.12.16.1 recommend showing pavement striping to show lane
width transition and provide a "R4 -8c Narrow Keep Left."
4. There is a future pedestrian bridge and crosswalk. By pulling back the median, the visibility clearance
has been improved. However, I would recommend adding future yield to pedestrian signs on both
sides of the travelway.
5. Call out the CG -2 for sidewalks east and west of the building.
6. Bumper blocks are required for parking spaces (west of the 5' sidewalk) since the sidewalk is less
than 2' from the edge of the parking area. Each bumper block shall be a minimum length of six (6)
feet, a maximum height of five (5) inches, and shall be securely anchored into the pavement in at least
two (2) places. If the sidewalk is increased to 6', bumper blocks will not be necessary.
7. 1 recommend improving the layout of the handicap parking spaces to provide persons with direct
unobstructed access to buildings by the shortest practical route, and to eliminate the need to cross
vehicular access aisles wherever possible. Please note that comment 6 applies if sidewalks are
provided in this area.
8. There is an existing 8" french drain on the final SDP for Phase 1 Northtown Center, running through
phase 2. Please clarify.
9. I recommend adjusting the grading on the forebay closest to the sidewalk. Pull back grading a
minimum of 2'. This area may require a guardrail. Please refer to Vdot A -34 if a guardrail is
warranted.
10. The biofilter is about 13' deep and I recommend placing a guardrail all along the travelway. I
recommend the same for the travelway with the retaining wall, with the guardrail starting at the 454
contour.
11. Please provide the easement DB # for utilities. The are labeled with missing DB and page #. Also
provide the ACSA widths where they are missing. Label the 20' access easement to the biofilter.
12. The 30' building setback and 10' parking setback are labeled incorrectly on plans.

13. There is a temporary easement for stream restoration work on Phase 1. Please show it on the Phase II
plans. One of the conditions from the critical slopes waiver approval is to provide downstream channel
and pond restoration upon project completion of phase 1 and 2.
14. The approved phase 1 plans included a safety rail. After conducting a field visit, I noticed the safety
rail was not installed. This is a 22' wall and is hazardous since the site is not fenced off.
15. Please update the existing topo. The plans are showing a retaining wall just east of biofilter, which is
not existing. Also, it appears the limits of the existing tree line has changed as well.
16. There are two sidewalk details. Based on the plans, only the detail with the curb is necessary.
17. Near the retaining wall south of site, the grading limit is right on the 20' undisturbed buffer. Extra
precaution should be take to protect the existing trees and root damage. Mark all trees to save.
Sincerely,
