The first submittal of the road plan set (SUB201300159) submitted 4 October 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, Mitigation, or
Stormwater Management. Please adequately address the following comments for final approval:
A. Existing Plan View Information
1) Please label the property parcel number and owner name for existing
parcel.
2) Please include existing topography for a minimum of 50' beyond
proposed limits of construction.
3) Please identify date and source of topographic information. All
topography should be at least visually verified by the designer within the last
year.
4) Please identify a benchmark location, elevation, and datum for
topography. An existing utility or other known position will suffice.
5) Please include existing FEMA FIRM number applicable to site on plans.
B. Proposed Plan View Information
1) Please label the edge of pavement — edge of pavement width and R/W
width for proposed road in plan view (appears to be Houndstooth Court).
2) Please include all proposed permanent easements, including stormwater
management easements over all facilities and associated structures and access.
3) Please include sight distance lines, for length at least 10' x speed limit of
Free Union Road, measured from a point 10' off the edge of pavement of Free
Union Road. These lines appear to be the basis for proposed sight distance
easements shown.

4) Scaled plan view for road plan indicates Houndstooth Court is proposed
at 20' width. However, typical section indicates 19' width. Please update
typical section to match plan view with a minimum width of 20'. Alternately,
road width could be reduced to 18' feet with no parking signs provided per
note 11 on VDOT Road Design Manual table B(1) -8.
C. Plan Detail Information
1) Please provide a traffic generation and distribution summary (i.e. proposed ADT
for Houndstooth Court and source for this information such as ITE Trip Generation
Manual).
2) Please utilize the propose ADT to provide a completed nomograph similar to
Appendix H from the VDOT Pavement Design Guide. This will be the basis for which
the D_R is determined. It appears applicant has stated a D_R of 6.4 is the correct
number; however there is no basis for the derivation of that number provided.
3) Please provide typical sections for proposed roadside ditches with locations
referenced by station.
4) Please include Albemarle County general construction notes from county Design
Standards Manual.
D. Street Details
1) Please include Albemarle County general construction notes for streets from
county design standards manual.
2) Proposed vertical curve k values appear to be insufficient for design speed of 25
mph (kmin = 12 for crest curves, kmin = 26 for sag curves). Will defer to VDOT
regarding acceptable geometry for public roads proposed.
E. Drainage Profiles
1) Please include existing ground line on culvert section submitted.
2) Please include scour protection at outlet for 30" crossroad pipe corresponding to
computations (see also comment F2).
F. Drainage Computations
1) Please include signed and sealed computations by a professional engineer or land
surveyor.
2) Please include scour computations for outlet protection for proposed 30"
crossroad pipe.
3) Please include a map with drainage areas, hydrologic coefficients, and times of
concentration for areas proposed to drain to each side road ditch as part of ditch capacity
analysis.
