amending.
2. All proposed slopes steeper than 3:1 must have low maintenance (not grass) ground cover
specified on the plan.
3. All entrances must have VDOT designations (PE -1, CG -9a, etc.)
4. VDOT approval must be obtained for any plan affecting right -of -way.
5. Please clarify arrow stripping in the parking area.

width of sidewalk.
9. Please show all utility crossings on the profiles.
10. Minimum pipe sizes into and out of the facility must be 15" diameter for maintenance.
11. It appears that the some of the runoff in post - development is now flowing to a SWM facility. The

12. With the added impervious from DA #2, please revise the size for the biofilter. If the facility is to
treat 50% removal rate, then the first 0.5" of runoff is to be treated. Please size the biofilter using
the 2.5% of the total impervious area. In addition:
- Please provide 2.5' of sand/soil media.
- The floor of the biofilter must be flat (0% slope)
- Please provide 1' — 1.5' of stone drain in geotech fabric under media, with 6" perforated
