The second final site plan and comps submittal (SDP201300024) submitted 8 November 2013 has
received Engineering Review and does not appear to meet Albemarle County minimum checklist
items for approval. This review does not include a review of Erosion & Sediment Control or
Stormwater Management. Please adequately address the following comments for final site plan
approval:
A. Application Information
1) Prior to final site plan approval:
water protection ordinance — erosion and sediment control and stormwater
management and
water and sewer
bonds must be calculated by the county (water and sewer bonds are calculated by
ACSA) and paid by owner after receipt of a Bond Request Form from owner.
(Rev]) Comment has been acknowledged.
B. Existing Conditions Information
1) Please include the date of the topographic information verification by the
designer. All topography should be at least visually field verified by the designer with the
last year.
(Rev]) Comment has been acknowledged. Please note the site should be visually
verified again and plans updated again by 11112014 if plan is not approved by then as
this marks potentially one year after the previous verification which was in 2013 per
note on sheet 2.

C. Proposed Plan View Information
1) Please propose minimum 20' wide drainage easements for maintenance of pipes
out of proposed drainage structures SD -D1 , SD -P1, and SD -P2 as shown on sheet 4.
(Rev]) Comment remains and also appears to apply to pipe out of proposed structure SD-
El.
2) Please label proposed curb type for all proposed parking lots in plan view. If all
proposed curbs are CG -2, a note stating as much on sheet 3 will suffice.
(Rev]) Please clarify if alternate curb proposed in detail 2112 on sheet 13 is a proposed
construction bid alternate, or a 2nd curb type.
3) Please remove apparent Diversion Dike line and temporary erosion & sediment
control symbols from sheet 5. Please note: outlet protection should remain permanent.
(Revl) Comment has been addressed.
4) Please update sheet 5 to include plotted drainage divides.
(Rev]) Comment has been addressed.
5) (Rev]) Plan elements proposed on sheet 3 do not appear to match with plan
elements proposed on sheet 10 including:
a) Outlet for drainage structure SD -P2
b) Depth for underground electric and telephone utility conduit
C) Fire hydrant proposed at west parking lot aisle terminus
d) Location for dumpsters in loading zones
Please make sure there is consistency among items proposed within the plan set
including intent for above four items.
D. Plan Detail Information
Sheets 12 and 13 have a total of 21 details labeled "A20 ". Please utilize unique
numbers to distinguish proposed plan details for plan clarity.
(Revl) Comment has been addressed.
2) Please provide a pavement section for the proposed concrete sidewalk and
dumpster pads per county Design Standard Manual (note strength requirements in plan
checklist). It appears that the upper detail labeled "Concrete Paving (Light Duty)" is
intended to be used for proposed sidewalks.
(Rev]) Comment has been addressed.
3) Please clarify locations for each "Concrete Paving (Light Duty)" detail in plan
view.
(Rev]) Comment remains. Plan view on sheet 3 does not clearly indicate where
"Concrete Paving (Light Duty)" is proposed.
E. Drainage Profiles
1) Please update drawing windows to indicate apparently clipped information from
Waterline `A' and Private Sanitary Lateral `Z' Profiles on sheet 9.
(Rev]) Comment has been addressed.

2) Please revise labels for proposed grade and existing grade for Storm `C' Profile
on sheet 9.
(Revl) Comment has been addressed.
3) Please depict all utility crossings for proposed drainage including proposed water
and sanitary sewer crossings in conflict with Storm `D' Profile on sheet 9.
(Revl) Comment has been addressed.
4) Please include by note or individual callout Inlet Shaping (IS -1) for all proposed
structures with a 4' or greater drop.
(Rev]) Comment remains.
F. Drainage Computations
1) Please update calculations and pipe design table for pipe run D3 -D2. Invert
elevations appear to be off by 100'.
(Revl) Comment has been addressed.
2) Please include times of concentrations on stormwater drainage area map on sheet 5.
(Revl) Comment has been addressed.
3) Drainage computations will be checked pending plotting of drainage divides (see
comment C4).
(Rev]) Drainage computations are acceptable; comment has been addressed.
