401 & BUFFER PERMITTING
Enclosed is a completed application submittal package requesting a Water Quality Certification (No.
3890, which corresponds with a US Army Corps of Engineers (USAGE) Nationwide Permit 42. This
application package consists of the following documentation: a completed PCN form, two maps,
construction drawings and a journal transfer of $240 from the Division of Parks and Recreation to the
Division of Water Resources.
The primary purpose of this project is to renovate and construct new mountain bike trails at Hanging
Rock State Park in Stokes County, NC. The project includes the installation of three hardened stone
stream crossings through perennial and intermittent streams as well as the installation of a 36" culvert at
an additional stream crossing.
DPR is concurrently submitting a permit application to the US Anny Corps of Engineers under NWP 42.
The request is being made to John Thomas who is the representative for Stokes County.
Thank You,

MEMORANDUM
TO: Tammy Dodd
FROM: Brian Strong
SUBJECT: 401 Water Quality Certification Application Fee for Hanging Rock State Park
Mountain Bike Trails.
Hanging Rock State Park is in need of a DWR Water Quality Certification (WQC) for impacts to
streams on the Moore's Spring property for the construction of mountain bike trails. The new
system will integrate existing trail with new, sustainable trail that will be accessible for several
different mountain bike difficulty levels.
Please prepare a funds transfer form in the amount of $240 payable to the NC Division of Water
Resources to cover the administration fee for the processing of this WQC request. The WQC is
required as part of a Nationwide Pen-nit application that will be submitted to the US Anny Corps
of Engineers for this project.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
This trail is being reconstructed to minimize the amount of stream crossings as well as renovate the existing trail in order to
make it more sustainable. The trail has been designed based on IMBA guidelines for sustainable trail building and the trail will
follow the natural contours. The new trail will reduce the average trail grade to 10% or less and will remove water from the trail
tread with the use of outsloping and drainage structures such as grade reversals and grade dips.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Much of the existing trail tread will be used and renovated to a sustainable state. Vegetative clearing will be confined to the
trail tread and will be done using hand tools. Appropriate sediment and erosion control measures will be used

Hanging Rock State Park
Moores Spring Mountain Bike Trails
Project Description
Hanging Rock State Park recently acquired property previously owned and managed by NC State
University. The Sertoma section of the property has approximately 8.4,miles of existing mountain bike
trails. These trails were developed and constructed by a local mountain biker who utilized many hours of
volunteer labor. Approximately 6.1 miles are located south of Moores Springs Road and are well
designed and constructed overall. Approximately 2.3 miles are located north of Moores Springs Road,
and while most of the existing trail design is acceptable, there are some areas that need to be improved
significantly. These improvements will provide a more sustainable trail that protects the resource and
offers a safer experience.
All proposed trails will follow the contours of the slopes. The trails will have an average overall
trail grade of 10 %, however steeper grades will exist for short distances based on trail difficulty.
Outslope and drainage structures (i.e. grade reversals and dips) have been designed into the trail layout
and will be constructed to make sure water is removed from the trail tread quickly to minimize resource
damage. The existing and proposed trail alignments are very close. The trail design attempts to
effectively keep users from shortcutting between alignments with dense understory vegetation
(mountain laurel) and natural features (ridges, creeks, valleys, steep slopes).
Two different features will be used to cross streams. Culverts will be installed throughout the
project at drainage sites as well as one culvert for a stream crossing, located on the Beginner Trail.
Culverts are sized based on drainage area and to make up for the difference in slope necessary for a
crossing. The proposed 36" culvert is expected to be much larger than necessary for the drainage area.
All other stream crossings will be hardened with natural stone found onsite. These crossings will be
built below grade of the stream bed to allow for the flow of water and aquatic organisms over top.
Trail construction will be completed using a walk behind skid steer machine as well as hand
tools. Stream Crossings will be built using hand tools and a small excavator in order to move rock
materials as well as placing the culvert. No equipment will be permitted to work within the stream.

NOTES:
1. IN- STREAM HARDENING SHOULD BE LIMITED TO EXISTING CHANNEL
DIMENSIONS - BANK TO BANK, EXISTING GRADE OF STREAM BED, & PROPOSED
WIDTH OF TRAIL.
2. LIGHT EXCAVATION WITHIN STREAM BED SHOULD NOT EXCEED 6" IN DEPTH.
3. MATERIALS - IN -STEAM CROSSINGS = 3 -4" WASHED TRAIL APPROACHES TO
STREAM = 1 -2" WASHED STONE AT MIN. OF 10 FT. AND A MAX. OF 25 FT.
4. INSTALL TRAIL DIVERSIONS WITHIN STEAM APPROACHES TOMINIMIZED
STORMWATER RUNOFF & SEDIMENT IN THE STREAM.
5. HARDENED CROSSING INSTALLATION SHOULD ENSURE PASSAGE OF LOW
WATER FLOW AND AQUATIC ORGANISMS WITHIN THE STREAM CROSSING.

GENERAL NOTE:
1. FOR CULVERT SIZING, CONSULT A PROFESSIONAL ENGINEER OR REFER TO "PERMANENT CULVERT SIZING
TABLE FOR FORESTRY" IN THE N.C. FOREST SERVICE BMP MANUAL TO CONSIDER UPSTREAM DRAINAGE AREA AND
ENSURE THE PASSAGE OF STORM FLOWS.
2. CULVERT MUST BE DESIGNED AND INSTALLED TO ALLOW PASSAGE OF AQUATIC LIFE DURING LOW FLOWS.
3. RIP RAP SHALL NOT BE PLACED IN THE STREAM BED CHANNEL.
4. A SECTION 404 /401 PERMIT WILL GENERALLY BE REQUIRED FOR CULVERT INSTALLATION OR REPLACEMENT
UNLESS:
A. PROPOSED CULVERT HAS THE SAME DIMENSIONS AS EXISTING CULVERT.
B. NO ADDITIONAL RIPRAP WILL BE ADDED OR ACCUMULATED SEDIMENT REMOVED WITHIN THE
STREAM CHANNEL.
C. CULVERT INSTALLATION IS NOT WITHIN A JURISDICTIONAL STREAM OR WETLAND AREA.
