Sheet 1
1. Provide Existing and Proposed impervious Area. (Rev. 1) Addressed.
Sheet 2
1. Check /revise scale as necessary. (Rev. 1) Addressed.
2. Existing sanitary manhole shown; locate and show Ex. sanitary lines. (Rev. 1) Not Addressed.
Recommend show Ex. San. MH and Ex. San. Lines.
Sheet 3
3. Check /revise scale as necessary. (Rev. 1) Addressed.
4. Provide STOP and YIELD signs to define and control traffic movement. (Rev. 1) Addressed.
Sheet 4
5. Check /revise scale as necessai (Rev. 1) Addressed.
6. Travelway:
a. Provide storm inlets /conveyance pipe channel design; review vertical fall across site (22');
provide computations that indicate Q2 runoff spread within travelways is less than 8'. Note: Since
travelway extends more than 100' without parking spaces, private road standards apply; ref
ACDSM 7.C. Lb. (Rev. 1) Partially addressed. As follow-up: C-301, recommend revise
pavement grade to ensure storm runoff reaches Str. #2 (6' L DI).
Also, provide curb cut at north corner of 7 parking spaces near new SWM basin, else storm runoff
will collect in the corner. Show /label curb cut on sheets C-201, C-301, and C-402 (inset detail).
b. Provide storm drain grate /drop inlet (type /length) and pipe (DIA, type, length, slope, Qlo
capacity, etc.) tables. (Rev. 1) Partially addressed. Asefollow-up: C-402 storm drainage profile
pipe slope and length are inconsistent with table values; please reconcile for consistency.
c. Provide plan /profile for storm system inlets and pipes. (Rev. 1) Partially addressed. Asfollow-
up: see 6.a./b., above. Also, per discussion, if storm pipe labeled New 15" HDPE @ 3.00% is
existing, revise label to read Ex. 15" HDPE @ 3.00%.

d. Carefully consider storm runoff in pedestrian /passenger drop-off areas during design storm events.
(Rev. 1) Addressed.
e. Provide spot elevations to ensure smooth transitions where travelways intersect, and to ensure
positive drainage and capture at storm grates or inlets. (Rev. 1) Partially addressed. As ollow-
yR: see 6_a., above.
f. Label storm pipe length, diameter, slope, and material in plan view. (Rev. 1) Addressed.
Comment withdrawn.
g. Clearly show and label storm inlets in plan view. (Rev. 1) Addressed.
7. Provide Note with WPO Plan Number (than accompanies Minor Amendment). Submit WPO Application,
if no WPO has been submitted. (Rev. 1) Not addressed. Applicant response: `WPO application shall be
included upon final submittal.' NOTE: Submit WPO as scParate application, not with final submittal.
VSMP /WPO plan must be approved prior to site plan minor amendment approval. Delay submitting
VSMP /WPO plan risks delay receiving MIA approval.
8. Ensure design meets quality and quantity criteria listed at 9VAC25-870-65 and 9VAC25-870-66,
respectively. (Rev. 1) Not Addressed. See item #7, above.
9. Ensure playground equipment, once reinstalled, maintains at least 2' horizontal offset from 15" HDPE pipe,
to avoid HDPE pipe penetration. (Rev. 1) Addressed. Comment withdrawn.
10. Specify RCP beneath parking lot and travelways, or ensure adequate cover (Albemarle recommends RCP).
Ref. VDOT standards and specifications. (Rev. 1) Partially addressed. See 6_c., above. Label 15" HDPE
Ex., if existing.
11. Provide profile for new 15" HDPE @ 3.0%. Provide details sufficient for installation and inspection.
(Rev. 1) Partially addressed. See items #6.c., and 10, above.
12. At parking lot SE of 20,600 SF building, provide 478' contour line. (Rev. 1) Addressed. Comment
withdrawn.
Sheet 5
13. Re. Albemarle County Engineering General Construction Notes, #3: Provide reference # for Approved ESC
Plan (WP020XX-XXXXX). (Rev. 1) Not addressed. See item #7, above.
14. Revise General Construction Note #4 to read Maximum Allowable slope is 31 (see ACDSM 8.A.2.) (Rev.
1) Addressed.
15. Revise General Construction Note #6 to read Albemarle County Engineer (not Director of Engineering).
(Rev. 1) Addressed.
16. Provide Details for:
a. Trench cut pavement repair (ref. VDOT; ensure pavement repair is wider than trench with seams
offset, else work may quickly degrade). (Rev. 1) Addressed. Comment withdrawn.
b. Storm pipe bedding detail, per VDOT spec. (Rev. 1) Addressed.
c. Retaining Wall (Typ.). Recommend show entire wall profile, as sheets 3 and 4 do not provide
adequate detail. (Rev. 1) Partially addressed. Asefollow-up: C-401 outlet protection table values,
Str. 3 show dimensions that exceed available space. Revise dimensions, taking into account
proposed depth of block (apparently 28").
New:
17. C-201:
a. Clearly identify location of all bollards; for example, Typ. of 6 and Typ. of 3 do not clearly show
locations of these nine bollards.
b. Label CG-12 ramp fronting left -most of five HC parking spaces in upper parking area.
c. Revise new 4' sidewalk to 5' width.
d. Strongly recommend CG-12 ramps for ADA accessibility at 3 locations: at end of new concrete
sidewalk that ends at lower 5-space parking area (1-HC; 4 parking); either side of new travelway
leading from upper to lower parking lots, so pedestrians requiring a ramp may cross from one side
of the travelway to the other, safely.

(16 c ) Outlet Protection Table. 81C-401 lists Str 3 OP = 10' x 1125' (L x W) while 1/C-402 Retaining Wall A Detail appears
to limit space available to 9' x 7' (stone OP) Please ensure OP dimensions fit space available Also please revise 1IC-402
horizontal scale to 1" =10'
