SUBJECT: REQUEST FOR ADDITIONAL INFORMATION
Carson Stout Stream Restoration - High Point Housing Authority
DWQ Project # 01 1810
Guilford County
Dear Mr. Hatch:
The Division of Water Quality has reviewed your plans for the culverting of 149 linear
feet and the restoration of 257 linear feet of an Unnamed Tributary to Richland Creek, Cape Fear
River Basin, Class WS-IV, Guilford County. Insufficient evidence is present in our files to
conclude that your project must be built as planned in waters and/or wetlands in accordance with
15A NCAC 2H .0506. Therefore, unless modifications of the proposal are made as described
below, we will have to move toward denial of your 401 Certification as required by 15A NCAC
2H .0507(e) and will place this project on hold as incomplete until we receive this additional
information. We are requesting (by copy of this letter) that the U. S. Army Corps of Engineers
place your project on administrative hold.
1. Your application did not include any stream restoration plans and specifications. Please
submit the following for our review and approval:
Site Plans/Maps
The site plans and maps must contain the information specified in Section 2.3.3 of The
Internal Technical Guide for Stream Work in North Carolina, April 2001 to include (but not
limited to) plan, longitudinal profile and cross-sectional views.
Morphological Measurements Table
Please complete the Morphological Measurements Table provided in Appendix B of the
above-cited Technical Guide.

Instream Structures
The location of any proposed instream structures must be provided on the site plans.
Complete typical plans for each type must be submitted as well.
Pebble Count
A pebble count should be provided for the entire stream reach. Since this channel is
currently culverted, we recommend that you obtain pebble count data from the un-culverted
section of the UT to Richland Creek directly downstream.
Sediment Transport Analysis
A sediment transport analysis can confirm that a stream has been properly designed. A
naturally stable stream transports its bedload in equilibrium so that there is no net aggradation or
degradation over the stream reach. As such, it is necessary that the predicted sediment transport
in the design stream be demonstrated to be in equilibrium to ensure overall stability will be
achieved.
Reference Reach
Please provide the precise location of the reference reach. Keep in mind that a reference
reach must be field-verified by DWQ staff and must be, in length, at least 20 bankfull widths or
two meander wavelengths.
Stormwater Inlet Location/Protection
Please locate any stormwater outlets to the proposed restored stream on the site plans.
Provide the means of stabilizing the stormwater outlets on the site plans.
Riparian Buffer and Planting Plan
A planting plan must be provided for the proposed stream buffers. The planting plan
should include woody vegetation planting densities of the appropriate native species that will
result in a survival rate of 320 trees per acre after five years. Please ensure that your site plans
reflect the Randleman Riparian Zones 1 and 2 and the planting detail. We recommend that you
use the Guidelines for Riparian Buffer Restoration, Wetlands Restoration Program, 2001
document.
Physical Monitoring
Please provide a physical monitoring plan. It is recommended that the plan be based on
the Wetland Restoration Program's Draft Physical and Vegetation Monitoring Outline (Success
Criteria) available at http://h2o.ehnr.state.nc.us/ncwetlands/restore.html.

Biological Monitoring
Biological monitoring is required for this stream restoration project. A written biological
monitoring plan based on the Benthic Macro invertebrate Monitoring Protocols for Stream
Mitigation Projects, also available at the website noted above.
2. Your application requests the after-the-fact authorization for the culverting of 149 linear feet
of stream channel. While we understand that you will be removing 257 linear feet of culvert
and restoring that section of channel, Section 401 Water Quality Certification cannot be
issued for the remaining culvert unless you obtain the proper variance(s) from the City of
High Point's Development Ordinance and possibly the State's Randleman Lake Water
Supply Watershed Protection Rules. Please address this issue.
3. Please be aware that the Division is requiring that stream and riparian buffer restoration be
completed by March 15, 2003. Please ensure that your final plans and specifications for this
project are submitted for our review by November 25, 2002.
Please respond, in writing, both to this Office and to John Dorney, 2321 Crabtree
Blvd., Parkview Building, Raleigh, NC 27604-2260 within 10 days of receipt of this letter
outlining your intent to proceed with this project or withdraw your application. If you
wish to proceed, please address the items listed above.
Sincerely,
Steve Mauney
