A. Initial Site Plan (SDP201500016)
Design at NW corner of building is problematic; Engineering cannot approve. Issues include:
a. With curved rather than straight 24' access from entrance to the west, sight distance is obstructed for
vehicles reversing from any of the 5 parking spaces along north edge of the site. [18- 4.12.15.d.]
b. Vehicles entering CVS from west entrance are unable to use drive -thru (if queue).
c. Loading zone striping/dumpster enclosure access conflicts with circulation: drive -thru, site (west entrance).
[18- 4.12.13.b.]
d. Insufficient stacking (100' Min, per Institute of Transportation Engineers: 5 -car minimum). [18- 4.12.6,
Drive -in lane serving any use]
This is a challenging sight. To address issues, please consider alternative design. Without revision, Engineering
cannot recommend site plan approval. One option that could likely be recommended with limited review /comment:
Shift drive -thru service window south, along west wall (recommend items 1 -13, if propose):
1. Shift loading zone striping to north face of building.
2. Eliminate 10.7' wide raised concrete median, NE corner, and 1- parking space so delivery vehicles may
park next to building. Stripe area.
3. Shift dumpster enclosure to other side of 24', 2 -way west entrance. Maintain 5.3' offset with property to
north.
4. Rotate dumpster /enclosure gates so waste service vehicles approach from west, not east.
5. Locate dumpster enclosure to allow room for waste service vehicles to maneuver.

6. Additional parking may be available west of 5 spaces along north edge of property (cast of relocated
dumpster enclosure).
7. Design 2 -way west entrance straight, without curve. Pattern after existing alignment (see CV- 101/Existing
Conditions).
8. Shift drive -thru service window south, along west wall of CVS (may extend wall/window 2.5' to serve
customers).
9. Widen drive -thru to 16' /entire length (bypass). If fire /rescue does not intend to utilize this paved lane as a
fire lane, additional width may be obtained by shifting curb west (closer to retaining walls) or by shifting
building outline, slightly.
10. North -south store dimension = 137.3'. With service window shift south, 100' stacking possible along back
(west) wall alone.
11. With shift south, 2 -way west entrance may include radius curve to provide immediate access to drive -thru
lane.
12. Shift drive -thru mERGE /entrance west, toward west end of (relocated) loading zone striping.
13. Recommend 24" STOP BAR/mirrors to enhance safety, SW corner of building. [18- 4.12.15.d.]
CS -101 (in Addition to 1 -13, above):
14. Show fire hydrant (FH) to remain/to be protected near south curb at Route 29 entrance.
15. Recommend 5' wide cross -walk to parking area located on property to the north, if properties share parking.
16. Show full extent of 565 -ft line of sight @45 mph/Seminole Trail. Also, include traffic control plan. It is
County understanding that VDOT requires a traffic control plan prior to site plan approval (Also, Traffic
Control Note, CS -301).
17. Pavement design inadequate: using weekday ADT =1926: DR = 3.48(ln ADT) - 1.48(ln SSV) -7.23 — 17.04.
DP = 14.67. Please revise: DP > DR.
18. Revise pavement sections such that subgrade elev. identical. Increase depth of light -duty pavement section
VDOT Type 1, 21A, as needed. Proposed parking aisle /parking space subgrades differ, which is infeasible
from a construction (or inspection) standpoint.
19. Revise all curb radii to 3'R, min. Also, double -check all curb radii; for example: R80.0, NW corner;
R48.5' (10.7' raised median, NE corner).
20. Label loading zone.
21. Label fire lane.
22. Label FH to remain (on site plan sheet).
23. Specify design of timber guardrail. Meet or exceed VDOT standard.
24. Show wire or rebar reinforcement, 5" concrete, Concrete Pavement Section.
25. Provide CG -12 ramp at raised island at bldg. exterior service /delivery door.
26. Recommend bollards where drive -thru is in close proximity to building.
27. Geotechnical retaining wall design required for final site plan approval (computations; plan/profile;
design/inspection/construction notes; safety rail details; drainage; backfill) — please call if questions.

28. VSMP required for site plan approval.
CE -101
29. Phase 1 E &S Control and Demo Plan must show interim existing conditions since VDOT grade- separated
interchange improvements will be complete prior to commencement of CVS construction.
30. Show CE as paved CE (PCE). Include paved construction entrance detail, Attached to comments.
31. SF cannot be installed as a perimeter measure prior to demolition of concrete median. Revise.
32. Add sequence of construction notes to preserve existing storm inlets closest to Rte. 29 as long as possible.
These convey runoff offsite. Once existing inlets are demolished, provide sequence that provides adequate
ESC measures at points of entry to storm lines A to V1, and X2 to V4. Furnish detail /s for ESC measure /s
that capture and filter runoff during construction. Runoff to Rte. 29 is impermissible. CE -101 provides
inadequate perimeter measures. Insert Additional Notes between construction sequence Notes 4 and 5.
33. Obtain temporary construction or grading easements from adjacent owners as necessary.
34. Revise Phase 1 probable construction sequence Note 1: Pre - construction meetings are held at COB.
35. Explain label "Ex. Detention system to be removed." There is no mention of an existing detention system
in SWM Narrative, CG -301. There is (generic ?) section titled Stormwater Detention Structures on CS -301.
36. Show stockpile location, if stockpile proposed.
37. Provide SWPPP. Recommend County template.
CE -501
38. SWM Narrative should reflect VPDES CGP /SWPPP inspection and maintenance requirements. Project
requires VPDES CGP (SWPPP). VSMP permit (CGP) required for site plan approval.
39. Project description states land disturbance is 1.54± Ac, but value listed as 1.59 Ac, elsewhere. Reconcile.
40. Project description (4t' paragraph) explains construction "operations are expected to begin once the
permitting process is complete." Revise to coincide with grade- separated interchange project completion.
41. Include paved construction entrance detail. (Attached).
CS -301
42. Provide Rte. 29 traffic control plan for VDOT review prior to site plan approval.
CG -101
43. Recommend eliminate MH/E, and instead locate an additional storm drain inlet in curb at west edge of
parking lot, with storm pipes between inlet F, new inlet, and inlet D.
44. Provide foundation drains for retaining walls, and connect to proposed piped conveyance system.
45. Calculate and provide inlet spread at inlets A, B, C, D, F. Provide inlet spread /capacity computations.
CG -301
46. Evidence of purchase of nutrient credits from Wildwood Farm is required prior to VSMP Approval.
47. Furnish VaRRM re- development spreadsheet, as .xls.
48. Revise Total Phosphorus load reduction required to 0.11 (lb /yr), consistent with VaRRM .x1s /reported pre -
/post- redevelopment ground cover.

49. Revise SWM Assumptions/Notes, Note 2, to address effects of removing existing detention. More detail is
required relative to existing SW detention system.
50. Revise SWM Note 4 to reference sheet CG -301.
51. Revise SW Quality Narrative to reflect 0.11 lb /yr phosphorus reduction, consistent with VaRRM .xls
52. Revise structure labels (storm drain design and hydraulic grade line calculations tables) to identify which
structures are existing (Ex.), and will remain.
53. Submit VSMP Application.
