RE: Final Site Plans(SDP201400047)
1. The landscaping within the 30' vegetation buffer and 20' land use buffer shall match
SDP201300035 (Amendment#3/SDP200600041), SUB201400066(Road Plan), WP0201300072
(Road Plan WPO),and WPO201400030(Underground storage amendment).
2. 18-4.12.13.a.—"Loading spaces shall be provided on the same lot with the use to which it is
appurtenant and shall be adjacent to the structure it serves." Loading spaces are not adjacent to the
gas station;recommend the two loading spaces be positioned more nearly adjacent to the gas
station.
18-5.1.20.a.—"The sale or storage of the petroleum products shall satisfy the requirements
established by the fire prevention code of the National Board of Fire Underwriters and the latest
edition of the"Flammable and Combustible Liquids Code,NEPA 30"of the National Fire
Prevention Association." From NFPA, Flammable and Combustible Liquids Code, 2003 Edition,
4.3.3.2.2,this excerpt:
[link: https://law.resource.org/pub/us/cfr/ibr/004/nfpa.30.2003.pdf]
4.3.3.2.2 Underground tanks shall be covered with not less
than 600 mm (24 in.)of earth,or with not less than 300 mm
(12 in.) of earth on top of which shall br placed a slab of
reinforced concrete not less than 100 mm(4 tn.)thick,Where
the tanks at c,or are likely to be,subjected to traffic,they shall
be protected against damage from vehicles passing over them
by at least 900 mm (36 in.)of earth cover,or 450 mm (18 in,)
of well.tantped earth plus either 150 mm(6 in.)of reinforced
concrete or 200 mm (8 in.) of asphaltic concrete.When as-
phaltic or reinforced concrete paving is used as part of the
protection,it shall extend ail leas: 300 men (12 in.) honron-
tally beyond the outline of the tank in all directions.
While design site features relating to placement of gasoline storage tanks, spill containment,vents,
etc,may be uncertain,please ensure depth of cover requirements. Confirm that concrete pad
detail,sheet 5,ties to area labeled gas pumps, sheet 4. If so,reference this detail(7"concrete,4"
#21-A stone base)on sheet 4. Identify approximate location of underground gasoline/kerosene
storage tanks to show that 7"thick slab extends at least 12"horizontally beyond the tank outline in
all directions.

4. Briarwood Commercial Development TIA by Davenport(Project# 13-338, 11/20/13,rev. 3/7/14)
shows 24-hr two-way volume trip generation for convenience market with gasoline pumps with 16
vehicle fueling positions as 8682. Sheet 5 displays this data using a double-end arrow and label:
"4,341 VPD". Revise label to clarify that 8,682 VPD is the TIA 2-way estimate. The figure 4,341
VPD may be mistaken as a total 2-way estimate,which it is not.
5. Note: ground cover hardier than turf grass is required for slopes steeper than 3:1. [ACDSM-8.A.2]
6. Sheet 4—Identify storm inlet structure with table value, T, spread at curb(ft)listed= 15.83.
7. Sheet 4—Revise proposed fence near townhouse lot lines to match proposed length of 5' wooden
fence shown on road plans(SUB201400066);on road plans,this fence extends farther south.
8. Sheet 3—Provide capacity/spread calculations and VDOT type inlet located between the two
F• terra units proposed for the NE .,4- • 4- .. kin. lot.
18-5.1.20.b.—"No storage to s and loading facilities shall be located closer a 4 •- •'red
=(100)feet from any lot line." Show that underground gasoline storage tanks are at least 100-

Comments:
1. Provide additional detail with proposed revised retaining wall design (9/17/14): provide Wall 1 and 2 cross-
section view that shows Wall 1 and 2 relative to one another. —ref sheet 4 of 8, 7/18/14 M. Circeo design, shown
as panel, plan sheet 17, 8-Aug/27-Aug -14 road plans.
2. Arrange revised retaining wall design as shown on prior plans, with requested item #1 appearing on sheet
17, and with Wall 1 and 2 profiles appearing as side-by-side panels on sheet 18.
3. Geotechnical sheets 4, 5, and 7 show 4-ft tall handrail at Wall 1 and 3. Geotechnical sheet 3 furnishes 2
details: handrail/fence post detail; sleeve-it fence post detail. Handrail detail is consistent with safety handrail.
Specify proposed location for sleeve-it fence post detail—if this detail is not required for safety handrail (Wall 1 and
3), please delete this detail. If two details are offered as equivalent options, select detail to be used; eliminate
detail not used.
4. Revise sheet 5 wall section views to show 4' handrail set behind wall, not in top course of block. Handrail
set in top course of block is consistent with Redi-rock wall system, not proposed system (Anchor diamond pro unit).
