Russell Avenue High Point, NC 27261 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. N. C. Division of Water Quality/Water Quality Section 585 Waughtown Street WWStnn-Salem, NC 27107 (336) 771-4600 Michael F. Easley, Governor William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality NMENR Customer Service 01 1810 Page 2 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. 01 1810 Page 3 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.
