SDP2020-00018
1. Recommend revise title to include ref. to project file number: SDP202000018.
2. Provide deed bk.-pg. ref. to interparcel access easements (Final Site Plan checklist, Easements, 4" item).
3. Major site plan amendment approval requires an Approved VSMP /WPO plan. Please submit VMSP
/WPO application at earliest convenience.
4. Include title sheet Note that preserved and managed steep slopes exist on parcels.
5. VMSP /WPO plan approval requires permanent SWM facility easement plat recordation (for any on -site
SWM facilities).
6. Provide brief narrative of Stormwater Management on C1. Consider stormwater quantity and quality in
context of increased impervious area /post -developed land cover, 100-year floodplain, stream buffer, etc.
7. Evaluate drainage feature at north property boundary for perennial stream features. Include note on plans
that perennial stream exists or does not exist on subject parcel. GIS stream buffer layer may be unreliable
at this location. Provide date of field evaluation, and any field data. Ref. code 17-600.A.
8. Show and label preserved and managed steep slopes on C3, C4, C5.
9. Resolve WP02018-00088, Amendment 1 as prerequisite to SDP202000018 approval (email, this date).
10. Revise C3 consistent with actual existing conditions (image, below). Shimp Engineering should have
access to designs for development on adjacent parcels to the west. Please rely on these, as well as satellite
imagery (for example: 3/13/20 —image, below) Also, please ref. Final Site Plan checklist for plan
reviewers, Existing conditions plan view information, I It item: `accurate current existing topography at the
time of submittal, including all existing features, and any recent disturbances.'

11. Show pipes as well as storm MH /inlet structures on C4, or turn storm utility MH /inlet layer off.
12. Revise loading zone east of existing service building, TMP 78-7, Lot 8, since not adjacent to the structure it
serves and since it impedes parking spaces to north, and circulation, generally. Ref. 18-4.12.13.a.b.
13. Provide autoturn figure for dumpster pad. Use single -unit (SU) truck design vehicle. Ref. Fig. 1, VDOT
Road Design Manual, Appendix 13(1), 20-ft wheelbase. Include entering site, reverse maneuver, and
exiting site.
14. Provide field survey data that supports note that `portion of preserved slopes disturbed is less than 25%.'
Engineering Div. has received no information that would exclude a portion of the steep slopes overlay
district (preserved steep slopes) from limits against disturbance or development found at 18-30.3.

15. Provide guardrail (VDOT GR-1 or GR-2) at top of 4', 13' and 6' proposed retaining walls along northern
edge of parking on TM 78-6, Lot 7. (Ref. Retaining Wall Plan checklist for plan reviewers, Plans, 2nd item).
16. Provide handrail (safety railing) labels for retaining walls over 4' high (see Retaining Wall checklist).
17. Engineering defers to VDOT on entrance requirements from Richmond Road, U.S. Rt. 250.
18. Engineering recommends provide distance from proposed revised entrance to adjacent entrances, east and
west (entrance 2, entrance 4, sheet C8).

19. Sidewalk at SE corner of new sales building (FIFE 419.50) appears < 5' w. Ensure all sidewalks are 5'
minimum width.
20. Label all sidewalk widths.
21. Label drive aisle width between curbing from entrance 2 to buildings that are interior to TM 78-6, Lot 7.
22. Provide CG-12 pedestrian ramps at each entrance: 2, 3, 4.
23. Wherever curb (CG-2) concentrates runoff against curbing, specify CG-6. Engineering understands this is
a dealership and that parking will be primarily for stored vehicles (automobile sales, services, and display).
Nevertheless, storm conveyance is critical to pavement integrity, which may affect retaining wall stability.
24. Include notes that this development:
a. May not impact preserved steep slopes,
b. Is not authorized to impact preserved step slopes,
c. Is subject to steep slopes overlay district requirements (18-30.3), and
d. That preserved or managed steep slopes will be staked /flagged prior to land disturbance, and that
flags /stakes will be maintained for the duration of the project, to final completion.
25. Proposed 4', 6' and 13' high retaining walls support parking (infrastructure). Please submit geotechnical
retaining wall designs (PE -sealed) to Engineering as prerequisite to recommendation to approve major site
plan amendment. Note: detailed geotechnical design is also required with building permit applications for
retaining walls.
26. Add SL-1 labels to profiles for MH ht. >12'. MH Str. A3 and A3a, for example.
27. At Str. A2 and any MH Str. with vertical drops > 4', include note /label for''/z" steel plate in floor of
structure. Ref. VDOT Drainage Manual, 9.4.8.7. (p. 9-37, 9-38).
28. Provide VDOT SL-I, IS-1, PB-I, GR-1, CG-6, CG-9a details on the plans (safety slab, inlet shaping, pipe
bedding, guardrail, curb /gutter, commercial entrance).
29. Provide and label dimensions of existing outlet protection at Str. Al. Design relies on existing riprap ditch.
Provide dimensions of existing riprap ditch (typ).
30. Design relies on existing ditch downstream of Str. Al. Include notes on plans that existing riprap ditch
meets design requirements for channel and flood protection for manmade conveyance, if that is the case.
31. If existing riprap ditch does not provide adequate channel or flood protection, provide adequate design.
32. Revise storm Al -A6 design. Every pipe in this run has velocity that exceeds (VDOT Drainage Manual
9.4.8.7.) 10 fps standard.
9.4.8.7 Maximum Grades
Slopes that incur uniform flow velocities in excess of 10 fps should be avoided because
of the potential for abrasion. Slopes in excess of 16% are not preferred because of the
need for anchor blocks. When anchor blocks are used, they should be installed at
every other pipe joint, as a minimum. (See Special Design Drawing No. A-73 and MA-
73 for Anchor Details for Concrete Pipe)
33. Provide retaining wall safety railing detail.
34. Provide LD-204, inlet design.
