Reviewer: Phil Custer
The site, ESC, and SWM plans for the Red Lobster at Fashion Square Mall, received on 22 May 2009,
have been reviewed. Comments for all three plans are provided in this letter. Although this plan has been
submitted as a preliminary, a full engineering review of the site was performed due to the completeness of
the plan set.
A. Final Site Plan [SDP- 2009 - 00043]
1. Not all critical slopes are shaded on the existing conditions sheet. It appears that critical slopes are
disturbed with this plan. If these slopes were created with a previously approved site plan, the
slope disturbance can be waived administratively by the lead planner. If a previously approved
plan cannot be found showing the creation of the disturbed slope, the waiver will have to be given
by the Planning Commission. Regardless, please provide a letter requesting this waiver referring
to all requirements detailed in Section 18 -4.2.5 of the Zoning Ordinance. The original site plan for
Fashion Square Mall is SDP -125. The final site plan for the Shoppes at Wachovia is SDP -2006-
00066.
2. A plat must be recorded before this site plan can be approved. The plat should include at least the
following: drainage easement for the pipe through the property, the private sanitary sewer
easement onto TMP 61 -122A, the public water easement, and a site and grading easement for the
parking and travelways on TMP 61 -132 (a boundary line adjustment would also suffice). The
width of the drainage easement must be calculated using the equation in the review checklist and
centered over the pipe.
3. Though the grading indicates otherwise, there does not appear to be a curb for the sidewalk around
the building. Please graphically show and label a curb in this area. Otherwise, please request a
waiver of the curbing in a letter addressed to the County Zoning Administrator. The only area
where a waiver would not be required is adjacent to handicap parking spaces.
4. Please adjust the grading in the loading space so that it is no steeper than 5%.
5. Please provide stop signs and bars at the cross intersection in the lower left corner of the site plan.
The stop signs and bars should be located on the approaches from the left and right.
6. Please install a sidewalk along Rio Road from the entrance to the Shoppes at Wachovia to existing
walk on the east side of the mall entrance. A crosswalk and pedestrian signals will also be
required across the mall entrance to make the connection safe. Please show all necessary
sidewalks, crosswalks, signals, and signage on the next submittal. [18- 32.7.2.8]
7. Please provide a traffic generation and distribution summary table.
8. Please provide VDOT standard inlet shaping (IS -1) on inlet #1.
9. Please provide spread computations on the curb line approaching the existing inlet.

B. Stormwater Management Plan [WPO- 2009 - 00024]
1. The impervious area on site is being reduced from 85% to 69% with this plan. Because of this, no
stormwater management (quantity or quality) will be required.
C. Erosion and Sediment Control Plan [WPO- 2009 - 00024]
1. The Erosion and Sediment control plan needs a phase II portion showing all final grades,
structures, and hardscapes.
2. The concept for the ESC plan shown is not acceptable. Since roughly the entire site drains to the
existing DI -3C, inlet protection shown here should be sufficient. Since the drainage area to this
inlet is likely between 1.5 and 1.75 acres a variance from the program authority will be required.
The program authority will approve this variation if the applicant provides a sump in front of the
inlet for settling, like the sediment trap inlet protection described on page III -37, in addition to the
block and gravel protection.
3. The silt fence in the middle of the site adjacent to the construction entrance should be removed.
Instead, a paved diversion should be added across the mouth of the entrance to direct all runoff to
the sediment trap inlet protection on the existing DI -3C.
4. Please update the County's General Construction Notes for Erosion and Sediment Control Plans to
include note 19 regarding Maintenance.
5. Please provide a safety fence around the entire project. The safety fence may also double as tree
protection.
6. Please show a soil stockpile area on the plan.
7. Please show a staging and parking area on the plan.
8. The ESC portion of the WPO bond will be calculated at the time of plan approval.
