Hunt, Jr., Governor Wayne McDevitt, Secretary A. Preston Howard, Jr., P.E., Director AS4 0-1 al AMON- NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES March 17, 1998 Wake County WQC 401 Project # 980209 APPROVAL of 401 Water Quality Certification Mr. George Worsley Vice Chancellor for Finance & Business NC State University Campus Box 7201 Holladay Hall Raleigh NC 27695-7201 Dear Mr. Worsley: You have our approval, in accordance with the attached conditions, to place fill material in waters for the purpose of rebuilding the dam at Lake Raleigh, as you described in your application dated March 6, 1998. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Number 3127. This Certification allows you to use Nationwide Permit Number 3 when the Corps of Engineers issues it. In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application. If you change your project, you must notify us and you may be required to send us anew application for a new certification. If the property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification. If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. This certification and its conditions are final and binding unless you ask for a hearing. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any questions, please telephone John Dorney at 919-733-1786.

PROJECT DESCRIPTION The project proposed involves: 1) repair of the principle and emergency spillways of Lake Raleigh Dam at their existing locations, 2) reduction of the slopes from 20° to 30 for stability and maintenance, 3) widening of the crest from 12 to 14 feet, and 4) raising the dam by one foot. The State recommended widening the crest to allow for proper maintenance. Project work will be confined to two areas; the existing dam and its immediate vicinity, which is approximately 3 acres and a soil staging area that is approximately 25 acres. The location of the project is on the North Carolina State University Centennial Campus and is represented in the Site Location Maps attached in Exhibits 1 and 2. B. PURPOSE OF PROPOSED PROJECT The Lake Raleigh Dam, located in Wake County, North Carolina, was originally constructed in 1914 and rehabilitated in 1985 to meet the State's Dam Safety requirements. Floodwaters resulting from Hurricane Fran in September of 1996 caused the two emergency spillways to fail and the lake to drain. The purpose of this project is to repair the principal spillway and the emergency spillways and restore Lake Raleigh. C. ALTERNATIVES ANALYSIS The only two alternatives are to either repair the dam or not repair the dam. If the dam in not repaired the result would be a forfeiture of Lake Raleigh, which would have a severe impact on the viability of Centennial Campus. This is not an acceptable alternative to the University. Lake Raleigh in its restored condition meets a variety of needs for the University and the extended community. The lake is an integral component of the Centennial Campus stormwater management plan and it provides fringe wetlands that filter stormwater and enhance biological diversity on the Centennial Campus. Lake Raleigh will be an important source of water for irrigation of the proposed golf course and can provide a valuable visual amenity for the campus. 1 'AM D. EXISTING ENVIRONMENT Topography The site is located at an elevation ranging from 270 - 286 ft mean sea level (msl) at the dam crest. Topography to the north of the dam slopes gently toward the water, whereas on the south side the ground rises steeply to about the dam crest height. Lake Raleigh is located in the Walnut Creek floodplain. Major drainage ways flow to the floodplain from north to south, varying in fall from 34 to 40 feet (Greenhorne & O'Mara, Inc., 1990). The Site Map - Existing Conditions (Exhibit 3) provides more detail on topography. The topography of the soils borrow area is essentially flat. Soils Extensive subsurface soil and geotechnical evaluations have been performed supporting the design process. Soil in the vicinity of the Lake Raleigh Dam is characterized by Cecil sandy loam (CeL) and Wake (Wke), both having fair to good infiltration, underlain by firm red clay primarily derived from gneiss and schist. These soils are gently sloping to steep and are subject to rapid surface runoff. The soil beneath the dam fill consists of alluvial deposits of clayey sand (SC) which overlays a thin layer of highly weathered gneiss. The deeper subsurface bedrock consists of a thick layer of moderately weathered to aboriginal gneiss and occasional mica schist (Applied Geosciences and Engineering, 1998 and Greenhorne & O'Mara, Inc. 1990). Soil test borings in the soils borrow area generally showed a four to six foot deep surficial layer of moderate to highly plastic red to red-brown silty clay soils that were generally underlain by tan to tan-red slightly clayey to fine sandy silts with traces of mica. Land Use The proposed project is located in the interior of Centennial Campus, with the nearest property line about 2,000 ft east of the site. Land use in the immediate area surrounding the Campus is primarily residential and woods. The area does contain intermittent undeveloped tracts and open spaces. Roadways and transportation corridors currently exist within the area and are subject to expansion. There are no farmed parcels of land within the project area. A detailed description of land use in the vicinity of the Centennial Campus is provided in the Environmental Impact Statement (EIS). The dam area directly impacted by the project has been subject to its current use since 1914. Prime or Unique Agricultural Lands Based upon the survey conducted for the Centennial Campus EIS, there are no prime or unique agricultural lands in the affected project area. Public Lands, Scenic and Recreational Areas . The Centennial Campus property is owned by the State of North Carolina and is allocated for management to North Carolina State University. There are presently no parklands or designated scenic areas existing on the proposed site. Lake Raleigh, however, provides some notable scenic value to the area as the future greenway trails and other informal recreational areas will benefit from the existence of the lake. Areas of Archeological or Historical Value Archaeological Research Consultants, Inc. conducted an archaeological survey of Centennial Campus in November 1997. In this survey, Mr. Thomas H. Hargrove identified no relevant discoveries of archeological or historical value within or near the proposed project area. Of the identified historical structures in the Centennial Campus area, the only structure noted in the Lake Raleigh Dam area was the original dam itself. Based on the noted locations of other artifacts in this report, it appears that no significant discoveries were made in the soil staging area either. A compilation of the results is referenced in the Centennial Campus EIS (Volume 2 Appendices). The soil borrow area does not contain any historic or archaeological features of relevance, as reported in the Centennial Campus EIS. Air Quality Existing air quality levels at the site are representative of general suburban/open space areas in the City of Raleigh. Wake County is currently in attainment of all national ambient air quality standards. Noise Levels Since the proposed site is undeveloped and is adjacent to campus development, existing background noise levels are representative of suburban/open space conditions. Wildlife and Their Habitats The National Institute for Urban Wildlife documented the aquatic and terrestrial ecology for the Centennial Campus EIS, reporting that the area supports three basic habitat types, however no endangered or threatened species were noted. Based upon this report, the areas affected by the project (dam area and soils staging area) are not unique or protected habitat areas. These findings were supported by field reconnaissance surveys conducted by Woodward-Clyde in February 1998. The soil borrow area is abandoned farmland that has been left unmanaged and is now primarily scrub-shrub and kudzu vegetation interspersed throughout. The area does not contain any endangered or protected species, or sensitive habitat, according to the Centennial Campus EIS. Wetlands Based upon the information collected by Greenhorne & O'Mara, Inc. and Woodward-Clyde there are no wetland areas affected within the dam project area, including the soil staging area. The wetlands delineation for the Centennial Campus EIS was conducted in accordance with the Corps of Engineers Wetlands Delineation Manual (1987) and classifications made in accordance with the Cowardin System. Though wetlands do exist throughout the Centennial Campus area, there are no delineated wetland acres that will be impacted by reconstruction of the dam. Shellfish or Fish and Their Habitats Shellfish and fresh water fish living within the surface waters in the immediate area affected by the dam reconstruction can be returned to comparable pre-storm levels only if the dam is repaired. Aquatic life was displaced as a result of the dam failure, but completion of the project will return the lake and downstream environments to conditions comparable to those before Hurricane Fran. Water Supplies Lake Raleigh is not designated as a public drinking water supply. Also, there are no public drinking water supplies in the area potentially affected by the project. Woodward-Clyde also reports that no adverse hydrologic or hydraulic impacts are expected once the dam is completed, normal lake levels are restored, and expected small peak flows occur. 4 AN Surface Water The site is located in the Neuse River Basin and the Walnut Creek floodplain. The dam is the discharge and flow control point between Lake Raleigh and Walnut Creek, which flows downstream. The Federal Emergency Management Agency (FEMA) has published a public notice in the Raleigh News and Observer describing the project and the reasons for siting the project in the 100-year floodplain, in compliance with Executive Order 11988. Groundwater Based upon geotechnical work performed for other projects on the Centennial Campus, depth to groundwater in the project area ranges from about 30 - 35 ft. E. ENVIRONMENTAL CONSEQUENCES Land Use Reconstruction of the dam will allow development of the Centennial Campus property as discussed in the Centennial Campus Master Plan. Dam reconstruction will have no deleterious effect on adjacent non-University land utilization. Air Quality Impacts to air quality during construction will result from dust and emissions created by operation of heavy equipment. These impacts will be minor and limited to the Centennial Campus property. All hauling roads will be wetted as necessary to reduce fugitive dust. Open burning of cleared debris will not be allowed. There will be no emission of air pollutants from the finished dam. Noise Levels Noise levels associated with construction that will result from this project will be confined to normal working hours and will be subject to existing local ordinances. The completed dam will not generate noise. Wildlife and Their Habitats The habitat that will be destroyed for the soils borrow area is not unique in the area. AIV Wetlands The are no classified or delineated wetlands in the dam project or soils borrow areas. The project activity is being conducted under a US Army Corps of Engineers Nationwide Permit No. 3. A Pre-Construction Notification for a Section 401 Water Quality Certification, as required by the State, has been submitted and will be obtained prior to beginning the project. A secondary impact of completion of the dam is the refilling of Lake Raleigh. Although the weir height will be two feet higher that the original dam, the lake level will be maintained at its original level at normal state. Therefore, the status of any wetland areas previously identified associated with Lake Raleigh will return to pre dam-failure conditions. The result should be no addition or elimination of wetland areas. Surface Water The construction process will have the potential to increase the silt loading to Walnut Creek downstream of the dam reconstruction project area. The potential for runoff from the soils borrow area impacting surface water will be minimal, due to the flatness and distance to a surface water body of the area. Lake Raleigh is an integral part of the Centennial Campus stormwater management plan. Therefore, with the dam in place and functional, there will be a positive long-term effect on water quality in Walnut Creek, downstream of the lake. Introduction of Toxic Substances Hazardous and toxic substances used during construction should be limited to fuel, oil and other lubricants. The construction contractor is responsible for properly managing these materials. There will be no operational uses of toxic substances. F. MITIGATION MEASURES The University is committed to ensure that development on Centennial Campus is conducted in accordance with responsible land stewardship, as well as with the recommendations and agreements included in the Centennial Campus EIS, approved Phase I Master Plan and Rezoning Conditions. The following measures are to be employed to mitigate the possible adverse environmental impacts of this project. Wetlands All appropriate permitting actions will be in place prior to starting the project. The project will not affect any identified wetland areas. 6 AM The Pre-Construction Notification for a Section 401 Water Quality Certification has been submitted to the North Carolina Department of Environment and Natural Resources, Division of Water Quality for approval. Surface Water Sedimentation and erosion control precautions will be implemented during the construction process to ensure that the potential for silt loading into Walnut Creek is minimized. A sedimentation and erosion control plan for the dam reconstruction area has been submitted to the North Carolina Department of Environment and Natural Resources, Division of Land Quality for approval (Exhibit 4). A sedimentation and erosion control plan for the soils borrow area will be submitted to the North Carolina Department of Environment and Natural Resources, Division of Land Quality for approval (and approval received) prior to beginning the project. The completed dam will have a positive impact on downstream surface water quality. G. CONCLUSIONS/FONSI In agreement with the approved Environmental Impact Statement for the NCSU Centennial Campus, this EA document indicates that no significant impacts to the environment will result from this project. A separate Environmental Impact Statement will not be prepared for this project. This Finding of No Significant Impact completes the environmental review for this project. A review summary will be published in the Environmental Bulletin. & REFERENCES Cawthorn, Joel W. 1970. Soil Survey of Wake County, North Carolina. US Government Printing Office. Washington, D.C.
