A. Erosion Control Plan (WP0201300008)
1. Please provide the recorded easement, permission letter, or documention from the Turtle Creek
Condominiums and Colonial Realty Limited Partnership for your proposed outfall pipe and future
SWM facility.
2. It appears that you will haul more fill to the site. Please show a stockpile location with silt fence.
3. The trees to be planted south of site should be included within the limits of disturbance. The
proposed waterlines should also be within the LOD. Please revise the LOD.
4. The sediment trap is undersized. Please revise.
5. For construction sequence note 2, please provide an outlet protection for the pipe.
6. The silt fence is hidden under the LOD line. Please clearly show the location of the silt fence east
of site. The LOD should be on the parcel unless easements are provided per comment 1.
7. Please provide the narrative for your project.
B. Stormwater Management Plan (WP0201300008)
1. The site is proposed to drain into an existing 48" RCP pipe owned and maintained by VDOT.
From there it drains through the townhouse site, then Stonefield shopping center, under Rt. 29 and
finally into the city. Adequate channels are required to be demonstrated. The contributing drainage
area, from your site, to a point of discharge is one percent or less for the total watershed area.
Please provide this analysis. Please be aware that there have been great concerns at the discharge
from Stonfield, and this site contributes to that flow directly.
2. It appears this WPO application changed from the previously approved WP0200700040. The
previous application included a cofferdam with a culvert inlet protection (CIP). Please refer to that
plan for guidance. It is our understanding that this was worked out with Greg Harper of the County
General Services Department.
3. It appears that you are proposing to install the riser for the future SWM facility. Please show the
the size of the basin and provide calculations for this future SWM facility to determine if the pipe
and basin are adequately sized. Also show the stormwater management easements that
encompasses the 100 year high water mark. These will be required prior to approval.
4. Please provide your stormsewer and outlet protection calculations.
5. Please provide the drainage easement for the proposed 15" HDPE stormsewer pipe and all existing
utilities with the DB and page no.
6. Please provide the manufacturer's certification and approval for your proposed Filterra design.
7. Also provide the load reduction calculation found on our website to meet the water quality criteria.

8. The 10' stormwater management access for the future SWM facility can be easily accessed by the
existing parking lot east of property. Please provide an approval letter from Colonial Realty
Limited Partnership for this use. Also provide the easement on the parking lot.
9. VDOT, ACSA and Fire Department approvals are required.
10. Please provide anchors for the pipe sloped at 16 %. Please refer to VDOT standards.
Sincerely,
Michelle Roberge
