All Engineering review comments addressed. Prior to submitting 4 copies for approval, please send .PDF of plan
sheet that shows, or revise plans in response to, 4/3/15 PLANNING comments (sent as email: 5/26/2015 12:00 PM):
"1. Label the dimensions and material for the trail/sidewalk along Carroll Creek Road or if this has already been
recorded, provide the DB and page number of the plat. This will need to be bonded with the road plans if it has not
already been bonded.
2. The trails should be bonded with this plan."
Planning Div. comments on 7 -May plan submittal expected by 6/8/15.
ACSA road plan review: pending (A. Morrison; 6/3/2015 10:00 AM email)
Do not submit final road plans until ACSA and Planning comments addressed.
VDOT comments: No objection (2 -June 2015)
With four (4) copy Final Road Plan submittal, please include application review fee /private streets -$400*
( *Rev. road plan reviewed 3 -Jun at/after Engineering review meeting (G. Murray) 2 -Jun, but without road plan Application fee.)
R o a d P I a n s (SUB201400215)
1) Sheet 4 — Provide design that will turn ditch flow from west (along Waterside Way) to south
(Osprey Drive). Qio (1.81 cfs) will not reasonably turn 90° at this location. Q2 will erode
roadway embankment. Option: install culvert pipe (80 -100' L) at 45° to transition flow west
to south. Alternatively, continue ditch west beneath Osprey, and revise VSMP as needed.
(Rev. 1) Addressed.
2) Sheet 4 — SWM Facility `C' Access, south of Lot 19: provide ditch north of access road to
intercept slope runoff /protect facility access. Direct runoff to the inlet of Culvert #28. (Rev.
1) Addressed.
3) Sheet 4 — Revise label proposed Ditch #1 to concrete flume (VESCH, Spec 3.16).
Recommend shading features which are either concrete ditch (VESCH 3.17), or flume (3.16).
(Rev. 1) Withdrawn. Applicant response: "Per VDOT drainage Manual 7.4.6.3.2, EC -3
Type A jute ditch allows for velocities up to 7 fps." Ditch #1 design Velz -yr? =5.57 fps /sheet 9.

4) Ref. VESCH for design requirements, concrete flume /Ditch #1. Furnish design, dimensions,
and details to aid construction. Transfer details /notes from VESCH Specs. 3.16/3.17, to plans.
(Rev. 1) Withdrawn.
5) Update VSMP to reflect VESCH technical specifications for concrete flume /stormwater
conveyance. Review VDOT standards for concrete conveyance (ref. VESCH/pg. III -137).
(Rev. 1) Withdrawn.
6) Sheet 5 — Revise road classification schedule Waterside Way VPD to 230 (10 VPD /lot). This
should not affect DR, or pavement thicknesses. (Rev. 1) Addressed.
7) Sheet 5 — Provide detail for asphalt walking trail where it meets driveways ( plan/profile).
(Rev. 1) Addressed.
8) Sheet 5 — Revise typical roadway sections. Dimensions indicate 49' and 57' RW width.
(Rev. 1) Addressed.
9) Sheet 7 — MH -31 to MH -27 profile/1\4H -27 to Ex. MH- CC -4 -1 profile: sewer mains between
26 -27 and 27 -28 to be ductile iron. Please revise. (Ref ACSA email: 3/30/2015 11:55 AM)
(Rev. 1) Addressed.
10) Sheet 8 — Revise storm pipe grade between Str. 6 and 4A: Max =16 %. This should not affect
MH type or design, or other elements of design. (Rev. 1) Partially addressed. As follow -
up, see ACDSM, 6. Drainage Systems (collection and conveyance), which provides link to
(.PDF) Engineering review drainage plans checklist:
ACDSM /Sec. 6
Revise: 16% max —If restore Str. #6 INN. OUT to initial 361.30', pipe 5 slope =14.1% (f).
(Rev. 2) Addressed.
11) Sheet 8 — Revise grade, pipe 7 or 9 such that INV elevations at Sir. 6 are not both 367.00.
These pipes connect with structure 6 at 55° an angle that may not work given dimensions of
MH penetrations required to accommodate 15" D1A storm pipes. Note max pipe grade, 16 %.
(Rev. 1) Addressed.
12) Sheet 9 — Include Culvert 28 in pipe design table. It differs fundamentally from driveway
pipes. (Rev. 1) As follow -up, reconcile Q10 pipe design/sheet 9 = 6.89cfs with Q10 culvert
design/sheet 10 = 7.27cfs. (Rev. 2) Addressed.
13) Sheet 9 — Ditch 2: indicate jute sections on profile /cross - reference table (Sta. 0 +00 — 2 +00).
(Rev. 1) As follow -up, restore Sta. From column (see initial RP). Ditch 2 table covers Sta.
3 +00 to Sta. 0 +00 (ref. initial RP). (Rev. 2) Addressed.
14) Sheet 9 — For each circle inset ditch detail, indicate slope 3: 1, consistent with typical road
sections, sheet 5. (Rev. 1) Addressed.
15) Sheet 9 — Ditch tables: include total ditch width, consistent with typical sections, sheet 5.
(Rev. 1) Addressed.
16) Sheet 10 — Provide separate plan/profile details for (DI -12) inlet 2 and inlet 10. Show Qio
depth = 8.2" and 7.5" respectively, profile views. Furnish design/spot elev. to guide grading.
(Cross - reference grades, sheet 4.) (Rev. 1) Addressed.
17) Include details for private entrances for private streets (Waterside Way and Osprey Drive),
and public streets. VDOT requires driveway entrance radius 20 -ft, Min. Alb. Co. will in this
case accept 12' radius driveway entrance on private streets. Inehide detaik, below. Indicate
on sheet 3 (or elsewhere) which entrance detail applies to Lots 24, 25, 26, Carroll Creek Road.
(Rev. 1) As follow -up, DELETE private entrance detail caption reference to Waterside
Way /Carroll Creek road intersection, and Waterside Way /Osprey Drive road intersection
since these are road intersections, not entrances. Retain 25' R at intersections, as shown on
sheet 3. (Rev. 2) Addressed.
Please call if any questions. Thank you.
