CERTIFIED MAIL - RETURN RECEIPT REQUESTED
Eric Keravuori, Director of Engineering
Town of Wake Forest
4011 Elm Avenue
Wake Forest, NC 27587
Subject: Proposed Northside Loop and Juniper Road Realignment in Wake County,
DWQ Project Number 20091109
Dear Mr. Keravuori:
Dee Freeman
Secretary
The NC Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification and
Neuse Buffer Authorization for the aforementioned project, along with additional information received in
response to our prior correspondence. In review of this additional information, DWQ has a few more
concerns:
1. Level Spreader A: The distance between the 310 contour line and the 308 line is much less than 30
feet. The area down slope of this level spreader is too steep and in addition, the level spreader is located
too close to the draw (less than 30 feet). The DWQ recommends that Level Spreader A be relocated so
that it is at least 30 feet from the edge of the riparian buffer (along its entire length). Then a 30-foot filter
strip with a slope of six percent or less could be graded and sodded to meet difuse flow requirements.
The graded area must be completely outside the protected riparian buffer.
2. Level Spreaders B and C: The bypass channels are proposed to pass directly through the vegetated
filter strip areas. This is not allowable.
3. Level Spreader H: The riparian buffer down slope of this proposed level spreader has a slope that
exceeds eight percent. The DWQ recommends that Level Spreader H be relocated so that it is at least 30
feet from the edge of the riparian buffer (along its entire length). Then a 30-foot filter strip with a slope
of six percent or less could be graded and sodded to meet diffuse flow requirements. The graded area
must be completely outside the protected riparian buffer.
4. Finally, for the vegetated filter strips that are proposed to be re-graded and sodded (B, D, E and
possibly A and H), please provide a specification for a layer of topsoil (the DWQ recommends six inches
in depth) and the type of sod you plan to use. Also, please provide watering specifications to establish the
sod.
