Martin, Governor Colonel Paul W. Woodbury Corps of Engineers Wilmington District P. 0. Box 1890 Wilmington, NC 28402 Dear Colonel Woodbury: S. Thomas Rhodes, Secretar January 20, 1987 r smt i! A N 2 1 1287 0A' 011LITY S&-, In keeping with your request, this office has circulated to interested state review agencies U. S. Army Corps of Engineers Public Notice .... 0538 dated September 25, 1986 which describes a project proposed by the Stokes County Watershed Commission of Danbury. The project, involving the construction of 22 earthen flood water control dams, is located on tributaries of the East Prong of the Little Yadkin River near King in Stokes County. Based on a coordinated agency review, this state viewpoint recommends approval of the project provided any permit issued includes conditions to protect or enhance riparian woodland habitat and overall water quality and minimum flow. Recommendations on these topics and the agency submitting each follow: 1) the N. C. Wildlife Resources Commission recommends that a minimum of 100 feet of forested habitat be protected around each pond's perimeter through I egally binding agreements. Perimeter management should not allow clearcutting or other land clearing activities. The Commission views such measures as necessary to balance expenditures of public monies and impacts on public resources within project benefits; 2) the Division of Water Resources recommends that cumulative instream flow targets be maintained at 2 locations on the East Prong Little Yadkin River. These flow targets are .6 cfs at SR 1168 (drainage area of 5.1 square miles) and 1.3 cfs at the downstream crossing of SR 1166 (drainage area of 10.5 square miles). When natural inflows are below these targets, then the target should inflow. These minimum flows could be maintained by several alternatives, separately or in combination, including: utilizing the low level drawdown gates on one or more of the larger impoundments, installing _a lower level release orifice-on the standpipe of one or more of the larger impoundments, or curtailing irrigation when pond levels drop below the standpipe opening. For your information, the Division of Environmental Management issued Water Quality Certification No. 1989 on November 7, 1986 for the project. P.O.

SAWC086-N-085-0538 September 25, 1986 ;k.. PUBLIC NOTICE STOKES. COUNTY WATERSHED IMPROVEMENT COMMISSION, Post Office Box 98, Danbury. North Carolina 27016, has applied for a Department of the Army permit TO PLACE FILL MATERIAL IN HEADWATER TRIBUTARIES OF THE EAST PRONG OF THE LITTLE YADKIN RIVER NEAR KING, Stokes County, North Carolina.. The following description of the work is taken from data provided by the applicant and from observations made during an onsite visit by a representative of the Corps of Engineers. Plans submitted with the application show the construction of 22 earthen flood water control dams on tributaries of the East Prong of the Little Yadkin River drainage basin. A plan for Watershed Protection and Flood Prevention for the Little Yadkin River Watershed was formulated and approved in 1965. The plan included construction of three (3) major flood water retarding structures. The dam on Crooked Creek was completed in 1971; the dam on West Prong in 1977. The present proposal represents an alternative to constructing one large dam (the third structure) on the East Prong Tributary. It is estimated that the small dams will control 3,954 acres of drainage area. They will be built under Soil Conservation Service Pond Standard 378, which provides a size limitation produced by the product of the storage times the height of the dam to be less than 3,000. An estimated 243,031 cubic yards of soil material, taken from onsite sources, will be needed to construct the dams. Of this amount, approximately 2,200 cubic yards will be placed below the plain of ordinary high water. The field survey of the dam locations revealed that regulated wetlands are not present at any of the sites. The purpose of the project is to provide for flood water control. Plans showing the work are included with this public notice. The State of North Carolina will review this public notice to determine the need for the applicant to obtain any required State authorization. No Department of the Army permit will be issued until the coordinated State viewpoint on the proposal has been received and reviewed by this agency, nor will a Department of the Army permit be issued until the North Carolina Division of Environmental Management has determined the applicability of a Water Quality Certificate as required by PL 92-500. This application is being considered pursuant to Section 404(b) of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within m2- the comment period specified in the notice, that a public healing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. This application is being considered pursuant to Section 10 of the River and Harbor Act of 1899 (33 U.S.C. 403). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this worksite is not registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer has determined, based on a review of data furnished by the applicant and onsite observations, that the activity will not affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest. Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards,.flood plain values, land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. -3- Generally, the decision whether to issue this Department of the Army permit will not be made until the North Carolina Division of Environmental Management (DEM) issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The DEM considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the Department of the Army permit serves as application to the DEM for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Environmental Management, Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. The North Carolina Division of Environmental Management plans to take final action in the issuance of the Clean Water Act certification on or after November 4, 1986. All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Environmental Management, Post Office Box 27687,-Raleigh, North Carolina 27611-7687, on or before October 27, 1986, Attention: Mr. William Mills.

A plan for Watershed Protection and Flood Prevention was formulated and approved in 1965. The watershed consisted of three (3) major flood water retarding structures, 31 miles of channel clearing and snagging, and stabilizing 251 acres of critically eroding land with grasses, legumes, or trees. Structure No. 6 on Crooked Creek was completed in 1971. An Environmental Assessment and Negative Declaration was prepared and distributed for public review for Structures 2 and 4 in 1975. The public review was completed with no unresolved conflicts or significant concerns. Structure No. 4 on West Prong was completed in 1977. The Sponsoring Local Organization has made a request to the Soil Conservation Service to find an alternative to building Structure No. 2 on East Prong Tributary and to eliminate clearing and snagging of the channels. The Soil Conservation Service made a study and found an alternative that satisfied the request and is acceptable to the Sponsors. Planned Action The alternative that would provide the same hydrologic and hydraulic effect below Structure No. 2 location is a system of 22 small dams. The cumulative effect of this system will provide the same stage-discharge at various cross sections located at strategic locations downstream. Therefore, the economic evaluation completed for the original plan i remains valid. Some additional benefits will accrue to cropland acres between the small dams and location of the deleted Site No. 2. It is estimated the 22 small floodwater retarding structures will control 3,954 acres of drainage area. All structures will be built under SCS Pond Standard 378, which provides a size limitation produced by the product of the storage times the height of the dam to be less than 3,000. Each structure will be designed to store the runoff from 25 year-1 day storm below the crest of the emergency spillway. The runoff from the 100 year-1 day storm will be routed through the emergency spillway to establish top of dam. Principle spillways will be heavy gauge welded steel and sized to have a release rate of 10-20 cubic feet per second per square mile (csm). Plasticity Index of soils used in the embankment will range between 8 and 15, with moderate piping and permeability potential. These soils will be located within the floodpool and emergency spillway areas. Filter drainage diaphragms will be used in lieu of anti-seep collars. A dual graded filter across the floodplain will provide protection from piping and allow proper embankment and foundation drainage. Rock excavation and/or concrete dental grout of the emergency spillway is anticipated on five sites. Sediment storage calculations will be based on complete land use and soils survey for each site, considering future conditions. Probable Impacts • Accumulated acres in permanent pools of the 22 small dams is estimated to be 75 acres. This compares to the original structure proposal of 68 acres. Area of floodpools will decrease from 133 acres to 54 acres. The site specific and accumulated land use changes are displayed in Table No. 1. t , The 22 pond size structures will contain a volume set aside for sediment ' accumulation over the design life of the structure and a volume for temporary floodwater storage. Landrights will be obtained by flood easements on private farmland. Most sites will be located in isolated and remote areas on private land. Therefore, public access will be too difficult to provide. Some landowners may permit public use by permission if accessibility is not a problem. Construction of the proposed 22 small dams will have no significant adverse effects on ecological systems in the watershed. Water quality in the streams should improve through reduction of sediment trapped by the structures. Frequent turbid conditions of the streams will be lessened, especially below the proposed structures. Water in the stream reaches downstream from the proposed structures may be warmed slightly because of the increased water surface area exposed to sunlight. Since no cold water fishing is present in these reaches or in Little Yadkin River as a whole, no adverse effects will result. Some increased groundwater recharge may take place immediately around the structures, but no measurable effect on the areal ground water supply is anticipated. The fishery resources in the watershed will be improved as a result of the proposed structures. A permanent fishery consisting of bluegill, largemouth bass, and other water impoundment species will be established where no significant stream fishery now exists. Construction of the 22 small dams will result in the loss of 11 acres of cropland, 45 acres of woodland, and 8 acres of pastureland. Species such as rabbit, quail and squirrel will be affected. It is proposed that .1-.2 acre of wildlife plantings of VA-70 or Bicolor will be planted in odd areas around each pond site. These concentrated areas should offset losses to wildlife food and cover for the species displaced and improve the carrying capacity of the surrounding area. The 54 acres of forestland and cropland in the temporary floodpool will not be significantly affected as wildlife habitat. No rare and endangered species will be affected by the impoundments. The aesthetic value of the area surrounding the structure sites will be increased. These reservoirs will fit in well with the rolling-to- mountainous topography of a region which now has a low water-land ratio in relation to quality of the landscape. The State Historic Preservation Officer was consulted during the environmental assessment for information on possible historical or archaeological resources within the affected area. No report of any resource of this type resulted from the inquiry. There are no historical sites within the watershed listed in the National Register of Historic Places. Prior to construction, an archaeological survey will be made of each site and consultations will be conducted with the North Carolina Cultural Resources Department. The project will comply with the Historic Properties Preservation Program, Public Law 89-665 (Section 106) and the proper authorities will be consulted if any archaeological or historical resources should be discovered. The accumulated average annual construction cost for the 22 structures is $37,225 including operation and maintenance cost. The benefits assigned to this system of structures is $40,200 average annual. lA Y' ??y '"V F'"'M1t ? ?r? ev T L,I? <f 4't Y.'? r rJi ?' S '+?jr `V., ?y? ': 4 ? 4 -,4... t N ?C' r 1? e y?

The backfill of the core and the run of the channel will be essentially the same for all dams built. The fill material for the core and the run of the channel for each site will consist of approximately four hundred cubic yards of soil material. The construction of the 22 small dams will consist of approxmately 243,031 cubic yards of soil material. Listed below is a break down per structure on the approximated yards for each site.
