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%. Engineering Review Comments Page 2 of 3 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.

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 Comment withdrawn. 10.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.

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.

(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.
