The first preliminary site plan and comps submittal (SDP201200042) submitted 17 July 2012 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,
Mitigation, or Stormwater Management. Please adequately address the following comments for
preliminary site plan approval:
Application Information
1) Per application plan for Old Trail Village, Road B and Road I are proposed to be
public roads. Please submit a separate set of road plans including proposed drainage and
profiles for Road B and Road I. Please note this will affect proposed property subdivision
lines shown as public roads are dedicated to be in public right of way.
Title Information
1) Please update vicinity map to more accurately locate this proposed project. Please
include a scale to vicinity map.
Existing Conditions Information
1) Please label the apparent limits of the 100 year flood plain for Slabtown Branch
on sheet 3. It appears these limits have been identified by a slashed area near the Old Trail
Drive crossing.
2) Please note date of original field topographic survey on sheet 1. Please field
verify existing topography and note as much on the plans. Existing topography must be
field reviewed within one calendar year of each submittal.
3) Please note the 100' stream buffer extends from the edge of all perennial streams.
This applies to the unnamed creek draining to Slabtown Branch. Please update the 100'
stream buffer line accordingly.
Proposed Plan View Information
1) VDOT approval is required for this project as it affects public right of way.

2) This parcel lies in the "For Bio- Filter Facilities" part of the Old Trail Village
rezoning plan per ZMA2004- 00024. Introducing biofilters to treat runoff from this
block will increase the stream buffer impacts to Slabtown Branch. Please indicate
proposed bio- filter and stormwater management easement locations. For impacts
proposed to the stream buffer for Slabtown Branch, applicant is required to provide a
mitigation plan for review and county approval. Please quantify in area the total
proposed stream buffer impacts proposed with this project. Please note only the
landward 50' of the buffer can be disturbed.
3) Please label Road B and Road I on sheet 4.
4) 2:1 fill slopes for Road B appear to be proposed. Please specify through note or
on landscape plan that low maintenance ground cover is required for all proposed slopes
steeper than 3:1
5) Please label retaining wall top and bottom elevations including the maximum
proposed height.
6) Please include safety railing for proposed retaining walls greater than four feet in
height. For proposed retaining walls within 2' of parking or travel way areas, please
include guardrail.
7) (for road plans) Please label proposed sidewalk and planting strip in typical road
section for Road I on sheet 3. Scaled R/W width for Road I appears to be 50' in width.
Please label R/W and face of curb to face of curb widths for Road I and Road B on sheet
3. Please match widths in typical sections on sheet 3.
8) (for road plans) Please label proposed crown superelevation for Road I and Road
B in typical section. Please draw proposed typical sections to scale.
9) Please label sight distance lines for all three proposed intersections. Sight
distance easements may be required.
10) Please label apparent proposed private or ACSA sanitary easement lines around
proposed 8" sanitary sewer by others.
11) Please indicate 20' wide drainage easements for all drainage crossing proposed
property lines.
12) Please update landscape plan to ensure no trees are proposed in conflict with
drainage or sewer utility lines.
13) Please label entrance radii.
14) Please label proposed parking stall width.
15) Please label length of proposed on street parallel parking spaces.
16) Please add a label to all proposed drainage structures for reference.

17) Please label each proposed entrance with a VDOT designation (e.g. PE -1, CG -9a,
etc).
18) Please include graphic scales for sheets 3 and 4.
19) Please include dimensions and labels for all proposed curb ramps and crosswalk
pavement markings.
20) Please include street name signs and stop signs at all intersections.
Plan Detail Information
1) Please include Albemarle County General Construction Notes.
Please adequately address the following comments for final site plan approval:
Application Information
1) Owner is required to provide a completed copy of the standard stormwater
maintenance agreement and fee for recordation for any stormwater management
facilities (including required bio- filters).
2) Runoff from this project will be detained by the Lickinghole Basin, a county
facility. Based on the proposed impervious surface area, the owner will be required to
pay a pro -rated share payment for use of the facility.
3) Prior to final plat approval, a separate set of Water Protection Ordinance plans
must be submitted and approved including: stormwater management plan, (streambank
impact) mitigation plan, and erosion and sediment control plan.
4) Prior to final plat approval:
water protection ordinance — erosion and sediment control, mitigation,
and stormwater management and
subdivision — road and sewer
bonds (a total of 5) must be calculated by the county (sewer bond is calculated by
ACSA) and paid by owner after receipt of a Bond Request Form from owner.
Title Information
1) Final site plan shall be signed, sealed, and dated by a professional engineer
Proposed Plan View Information
1) (for road plans) Please include proposed traffic derivation for Road I and Road B
based on TTE Trip Generation Handbook or equivalent.
2) (for road plans) Please propose a pavement design on typical sections for Road I
and Road B which supports proposed traffic loadings per 2009 VDOT Pavement Design
Guide for Subdivision and Secondary Roads in Virginia or equivalent.

3) (for road plans) Please label proposed curb type for Road I and Road B in typical
section.
Plan Detail Information
1) Please provide a pavement section for the proposed dumpster pad per county
Design Standard Manual (note strength requirements in plan checklist).
2) Please provide a pavement section for the proposed concrete sidewalk per county
Design Standard Manual (note strength requirements in plan checklist).
3) Please provide a detail for the proposed retaining wall including railing or
guardrail in section.
4) Please provide details for any pipes or drainage structures through or under walls.
5) Please label all proposed parking lot island (minimum 3') widths and radii.

minimum of 10' x 10' with an 8' in front for wheel bearing.
9) Please propose drainage structures and pipes for Road I.
10) Please introduce inlets or grading to keep the principal parking lot access free of
flooding during a 100 year storm and site runoff from draining out to Road B.
1 l) Please regrade south parking lot or otherwise ensure that drainage runoff does not
backwater in dumpster area [18- 4.12.19].
12) Please include stationing for Road I and Road B on sheet 3 at 50' minimum
increments.
13) Please label horizontal curve start points, end points, and radii which meet
applicable VDOT standards.
14) Please provide a VDOT approved temporary turnaround for Road B just north of
intersection of Road I.
15) Please include a typical retaining wall detail. A typical manufacturer's drawing
