Reviewer: Max Greene
1. Road and drainage plans (SUB201200152)
VDOT comment: The alley entrance widths must be 24 ft for the entrance throat length of 35 ft,
but can then taper down to 20 ft.
a. VDOT approval is required. [DM905]
b. Please show stop signs on alley intersection with public roads.
c. County E -911 road name signs are not to be attached to State required traffic
control signs. Please show separated signs for each on all intersections.
Generally, "Stop" signs are on the right side of the intersection and the E_911
"street name" sign is on the left.
d. Please show the signs more prominently if they are not going to be individually
labeled on the road plan.
e. Please show "No Parking" signs with arrows at the beginning and end of no
parking areas with additional "No Parking" signs every 100' or more often
between end designation signs. Appears only Colbert Street requires "No
Parking" signs.
f. Typical street section for Colbert Street needs to show the crown in the road
centered on the travel -way with parking on one side of the travel -way and "No
Parking" signs on the other.
g. Appears parking is allowed on both sides of Dabney Grove, Griffen Grove and
Farrow Drive. The "No Parking" signs for these roads may be removed from the
plan.
h. Please show Farrow Drive 34' curb to curb for the entire length as stated in
VDOT preliminary comments and remove note stating the road is to be narrowed
between Dabney Grove and Butler Street.
i. Please show sight distance easements on the planting plan for review.
j. Alleys need drop inlets installed along the edge /curbing and on each side of
entrances to prevent the runoff producing storm event from entering the street.
k. Please change all turning radii to a minimum 25' as required in the preliminary
plan approval.
1. Miles and Philips alleys are shown with over 10% slopes.

2. Stormwater Management and Mitigation Plan (WPO201200096)
a. Please provide an adequate channel analysis for runoff from proposed
construction. Analysis could be proven given:
i. Adherence to VESCH MS -19 requirements (see 4VAC50- 30 -40, MS -19
sec. b (1)): The applicant shall demonstrate that total drainage area to the
point of analysis within the channel is one hundred times greater than the
contributing drainage areas of the project in question. A report or plan
depiction with analysis to this point could prove channel adequacy.
ii. adherence to VA code 10.1- 603.4(7): essentially, the required condition
for an on -site solution without looking downstream for a 24 hour 1.5, 2,
and 10 -year intensity event -
(post - development) Peak flow rate <= Pf *Vf/Vp
Where Pf = peak flow rate in a forested condition
Vf = runoff volume in a forested condition
Vp = runoff volume proposed
b. Type III retention basin does not appear designed in accordance with VSMH 3.06.
Basin appears to be a shell for the construction of a retention basin. Please show
appropriate shoreline fringe, riparian fringe, and flood plain terrace vegetation in
accordance with expected frequency and duration of inundation. Selection and
installation guidelines should be per Minimum Standards 3.05, Landscaping.
3. Erosion Control Plan (WPO201200096)
a. Please add this note to the plan "SB #1B will not be removed until the road and
drainage system is installed and approved by the WPO Inspector."
b. A portion of the proposed grading and retaining wall are off the page in the lower
right hand corner of the plan sheets. Please show the entire project for adequate
review. Additional comments may be forthcoming due to missing information for
what appears to be an unprotected swale and wall construction.
c. Please show the full extent of the paths to be constructed and how they will be
protected.
Fire and Rescue Comments:
Based on Road Plan dated 12/13/12
1. Fire Hydrant spacing shall be 500 feet per travelway. I have the PDF copy showing
the hydrant locations discussed with your office.
2. Turning Radii shall be no less then 25 ft
3. Roads with parking on one side shall be marked 'NO Parking" per the VSFPC
D103.6
4. All roads need to maintain a 20 ft wide clear path of travel at all times. Streets need to be
marked accordingly.
