Dear Mr. Edwards
On May 17`", 2007, Mike Horan, from the Division of Water Quality (DWQ) met with you on-
site at Spring Garden Lane near Henrico in Northampton County to discuss your restoration
efforts. During this inspection Mr. Horan observed the culvert installations and the status of the
sediment removal. On May 24, 2007 Mike Horan discussed with you (via the telephone) areas
that require further work. The following is a summary of what requires further work from the
site inspection on May 17`", 2007:
1. The outlet of the new culvert on Sprin>? Garden Lane (downstream end
^ Remove any deposited sediment within the channel above the check dam. It is
recommended that you use hand labor (buckets, shovels and wheelbarrows) to
remove deposited sediment from the stream channel. The sediment should be
removed from the channel, taken to high ground (more than 100 feet landward from
the stream channel) and stabilized.
^ When all work is completed (as described above and below), remove the check dam
from the stream.
2. Gravel driveway crossing (including downstream channel) on West Sde_ of Springy
Garden Lane
^ The placement of culverts in waters must be placed below the elevation of the
streambed to allow low flow passage of water and aquatic life. During the inspection
I noted that the placement of this culvert was perched ~ 2 feet above the streambed at
the downstream end. Please note, in your 401 Water Quality Certification you
indicated the culvert would be installed according to State requirements. Please
modify the culvert to the specifications in your plans (see the attached drawing from
your 401 Water Quality Certification titled "Section B-B").

^ Install a plunge pool system, similar to the one installed on the east side of Spring
Garden Lane, on the downstream end of the culvert.
^ Use large, flat boulders to make the steps. Make sure the boulders are level and
secured into the streambed and sides of the channel.
^ Make the elevation of the first pool so it is almost level with the outlet of the culvert.
^ Each subsequent plunge pool should be 6-12"below the previous pool, resulting in
approximately two to four plunge pools. The boulders used to separate each pool
should be placed such that the water cascades over the boulders.
^ Remove any deposited sediment within the channel as described above.
^ Stabilize the banks with vegetation and riprap (use riprap only as needed).
Please note: The installation of a plunge pool system below the gravel driveway
crossing on the west side of Spring Garden Lane may require a modification to the
application you submitted to the Division of Water Quality and to the US Army Corp
of Engineers.
3. Stream clean un from Spring Garden Lane to Butler Drive and below Butler Drive
^ Areas requiring further sediment removal were flagged during the site visit.
Sediment should be removed in the areas where sediment is more than 2 inches in
depth. Please make sure to remove any deposited sediment within the channel as
described above.
DWQ will be conducting another site inspection, to ensure the above mentioned steps have
been satisfactorily completed. Please note that if these steps are not completed there may
be additional civil penalties levied of up to $25,000 per day for each violation. Please feel
free to call Mike Horan at (919) 791-4200 or Karen Higgins at (919) 733-5083 ext. 574 if you
have any questions or concerns. Your attention to this matter is greatly appreciated.
