DESCRIPTION 5 Request for USACE IP modification These are transmitted as checked below: ? As requested ? For approval ? For review and comment Remarks: Copy to: Date: November 30, 2006 Job No.: ® For your use ? For Signatures Signed: Harold Brady Project Biologist CSC " - L'TY ULT.. Li` L' ENGINEERS & CONSULTANT0, November 30, 2006 U.S. Army Corps of Engineers Washington Regulatory Field Office 107 Union Drive, Suite 202 Washington, NC 27889 ATTN: Mr. Tom Steffens Regulatory Permits Specialist Dear Mr. Steffens, Subject: Dare County Justice Center Administration Building - Request for Permit Modification The purpose of this letter is to request, on behalf of Dare County, the amendment of United Sates Army Corps of Engineers (USACE) Individual Permit (IP) No. 2006-32369- 128. The permit authorizes 0.95 acre of impacts to federally jurisdictional wetlands associated with the construction of the proposed Dare County Justice Center Administrative Building and associated facilities. The project area is located on Roanoke Island near the intersection of US Highway 64 and US Highway 264 Business in Manteo, Dare County, North Carolina. Communications were made with the North Carolina Ecosystem Enhancement Program (NCEEP) immediately after issuance of the IP. This communication was conducted to ensure that all of the general conditions and special conditions were agreeable to all parties involved. At that time NCEEP indicated that they had an issue with Special Condition "p", which states "In order to compensate for impacts to 0.95 acre of waters and wetlands, the Permittee shall make payment to the North Carolina Ecosystem Enhancement Program (NCEEP) in the amount determined by the NCEEP, sufficient to perform the restoration of 1.90 acres of non-riparian wetlands within the USGS 8-digit hydrologic code (HUC 03010205), located on the south side of the Albemarle Sound." NCEEP's issue with this special condition is that the permit specifies where the compensatory mitigation must occur on a finer level than the HUC unit. Stating that the compensatory wetland mitigation must occur on "the south side of the Albemarle Sound" does not meet the terms of the existing approved Memorandum of Understanding between the North Carolina Department of Environment and Natural Resources (NCDENR) and the USACE dated November 4, 1998. Therefore, NCEEP can not accept this project into their program with the current wording of special condition "p". According to our telephone discussions, this wording came directly from a previously issued Individual Permit (Action ID: 200011238) associated with the original construction for the Dare County Justice Center. Upon further review of the documentation associated with this separate IP, information surfaced that the North Carolina Wetlands Restoration Program (NCWRP) (former name of the NCEEP) had not accepted the special condition at that time either. A request was made to the USACE by Quible & Associates on behalf of Dare County in a letter dated June 13, 2001, to amend this MULKEY INC. 6750 TRYON ROAD CARY, NC 27511 PO Box 331 27 RALEIrH, NC 27636 PH: 91 9-©51.191 2 FAx: 919-851-1910 WWW.MULKEYINC.COM November 30, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 2 special condition to essentially remove the phrase "located on the south side of the Albemarle Sound". The USACE agreed to this modification to the IP in a letter dated July 10, 2001, signed by Mr. G. Wayne Wright, Regulatory Division Chief. Both the Quible letter to the USACE and the USACE letter to Mr. Terry Wheeler, the Dare County Manager are attached. In closing, Dare County is requesting that the phrase "located on the south side of the Albemarle Sound" be removed from Special Condition "p" and that the location of the compensatory mitigation for impacts permitted on this site be limited to HUC unit 03010205. Approval of this request is necessary to meet the existing approved Memorandum of Understanding between the NCDENR and the USACE dated November 4, 1998 and allow Dare County into the NCEEP program. This will allow Dare County to meet their compensatory mitigation requirements as described in Special Condition "r" once full payment is made to NCEEP for wetland impacts approved by the IP No. 2006-32369- 128, dated November 7, 2006. Thank you for your attention to this urgent matter. If there are any questions or need additional information please contact Harold Brady at (919) 858-1804 or by email at hbrady@mulkeyinc.com.

Neff The purpose of this correspondence is to request, on behalf of Dare County, the amendment of US Army Corps of Engineers (COE) Individual Permit (IP) CAID # 200011238, The permit authorizes impacts to Department of the Army (DA) wetlands associated with the construction of the Dare County Justice Facility. The subject property is located 660 feet northwest of the intersection of US 64/264 and NC 345 on Roanoke Island in Dare County, North Carolina. Based on the 6/13/01 meeting that you, Al Cole, Dare County attorney and I had in Mr. Cole's office, the requested amendment to the IP relates to Special Condition c. That condition specifies requirements for payment to the NC Wetlands Restoration Program for the restoration of 5.46 acres of forested wetlands and further defines the Hydrologic Unit in which the restoration can be located. Specifically, the condition requires that the restoration be "within the portion of the 8-digit USQS Hydrologic Unit, HUC 03010205 located on the south side of the Albemarle Sound." I further reference our 6/13 discussions with Mr. Ron Ferrell of the NC Division of Water Quality (DWQ) concerning available sites on the south side of the Albemarle Sound. He indicated that there were at least two under consideration but that there are, at present, no approved sites in that area. He further stated that he felt that a site would be available within the one year time frame allowed in the MOU but could not guarantee that outcome. Therefore, Dare County requests that Special Condition c be amended to indicate that Dare . County, in coordination with the DWQ, will make all efforts to find a site within the specified hydrologic unit, but that if no site is available, the condition be amended to allow a site to be utilized in HUC 03010205 without reference to a particular area within the unit.

Also reference the June 13, 2001, correspondence from your agent Quible and Associates Inc., requesting that Special Condition c.

Linear interpolation should be employed to determine the correct value for non- standard table entries. In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide 90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal. II.

WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check ogre) 0 does oes n incorporate a vegetated filter at the outlet. This system (check one) 0 does 0 does not incorporate pretreatment other than a forebay. Form SWU-102 Rev 3.99 Page 2 of 4 Maintenance activities shall be performed as follows: 1. After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). The measuring device used to detennine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads -Z 25 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads - I.5 feet in the forebay, the sediment shall be removed.

U N N L 20 The capability subclass is Vlw. Based on loblolly pine as the indicator species, the ordination symbol is 9W. JoA-Johns loamy sand, 0 to 2 percent slopes. This nearly level, moderately well drained and somewhat poorly drained soil is on low, smooth ridges on Roanoke Island and in Manns Harbor. The smaller mapped areas are commonly oval, and the larger areas are irregular in shape. The size of the areas ranges from 3 to about 100 acres. Typically, the surface is covered with 3 inches of partially decomposed needles, leaves, and twigs. The surface layer is very dark gray loamy sand about 4 inches thick. The subsurface layer is gray loamy sand about 4 inches thick. The upper part of the subsoil is very dark brown loamy sand about 5 inches thick. The rest is about 13 inches thick. It is yellowish brown sandy loam in the upper part and yellowish brown sandy clay loam in the lower part. The underlying material to a depth of 72 inches is sand. It is light yellowish brown in the upper part, very pale brown in the next part, and light brownish gray in the lower part. Permeability is moderate to rapid. The soil is very strongly acid or strongly acid. The seasonal high water table is 1.5 to 3.0 feet below the surface. Included with this soil in mapping are small areas of Baymeade and Icaria soils. Baymeade soils are on the slightly higher knolls. Icaria soils are in slight depressions. The included soils make up about 10 percent of the map unit. The Johns soil is used mainly as woodland. The dominant vegetation is loblolly pine, sweetgum, persimmon, live oak, and water oak. Wetness is the main limitation affecting woodland. The Johns soil in Dare County generally is not used for agriculture because of the lack of active farming on Roanoke Island and in Manns Harbor. Wetness is the main limitation affecting farming. The main limitation affecting urban and recreational uses is wetness. Also, the soil is too sandy for some urban uses. The wetness can be reduced by installing perforated drain tile, drainage ditches, or a combination of the two systems. The capability subclass is Ilw. Based on loblolly pine as the indicator species, the woodland ordination symbol is 9W. LeA-Leon fine sand, 0 to 2 percent slopes, rarely flooded. This nearly level, poorly drained soil is on Roanoke Island and in Manns Harbor. It is on flats and in slight depressions. Mapped areas are irregular in shape and range from 5 to 50 acres in size. Typically, the surface layer is dark gray fine sand about 7 inches thick. The subsurface layer is light gray Soil Survey sand about 8 inches thick. The subsoil is sand about 8 inches thick. It is dark brown in the upper part and dark reddish brown in the lower part. The underlying material to a depth of 72 inches is gray sand. Permeability is moderate to rapid. This soil ranges from extremely acid to strongly acid throughout. The seasonal high water table is at or near the surface. The soil is subject to rare flooding. Included with this soil in mapping are small areas of Icaria soils and areas of soils that have a dark surface layer more than 10 inches thick. The included soils are in landscape positions similar to those of the Leon soil. They make up about 10 percent of the map unit. The Leon soil in Dare County generally is not used for agricultural purposes. Wetness, flooding, and a scarcity of adequate drainage outlets are the primary limitations affecting agricultural uses. This soil is used as woodland. Loblolly pine, live oak, and water oak are the dominant species. The most common understory plants are waxmyrtle, fetterbush lyonia, gallberry, and American holly. Wetness in winter is a limitation; however, this soil is droughty during the growing season. The main limitations affecting urban and recreational uses are wetness, flooding, seepage, and the sandy texture. The capability subclass is IVw. Based on loblolly pine as the indicator species, the woodland ordination symbol is 7W. NeC-Newhan fine sand, 0 to 10 percent slopes. This excessively drained soil is on dunes on the Outer Banks. It commonly is adjacent to the Beaches-Newhan complex. It is within the salt-spray zone and supports salt-tolerant vegetation. Mapped areas are elongated and range from 2 to 1,300 acres in size. Typically, the surface layer is light brownish gray fine sand about 2 inches thick. The underlying material to a depth of 80 inches is fine sand. It is light yellowish brown in the upper part and very pale brown in the lower part. Permeability is very rapid. The soil ranges from moderately acid to mildly alkaline. The seasonal high water table is more than 6 feet below the surface. Included with this soil in mapping are small areas of Duckston and Corolla soils. These soils are in the lower, wetter troughs or depressions. They are common throughout the map unit. They make up 10 to 15 percent of the map unit. Most areas of the Newhan soil are covered with salt- tolerant grasses and shrubs. Some areas are used as sites for beach cottages, for recreational development, or as wildlife habitat.

An extended detention wetland must be also be designed with a forebay, as is a wet ' detention pond. The major difference between an extended detention wetland and a wet detention basin is that the ' allocation of surface area to different pond depths. For the system to function as a wetland, 70% of the area of the permanent pool needs to be designed as a marsh with a depth of 0 to 18", with an almost equal distribution of area (35% and 35%) between 0" to 9" and 9" to 18." The other major difference is that ' there needs to be a small pool (15% of the surface area) where the outlet is located to prevent sediment from interfering with the outlet structure functions. The balance of the area is flexible with respect to depth. ' A most important consideration when designing both extended detention wetland systems and pocket wetland systems is the specification and installation of plants. Tables 4.1, 4.2, and 4.3 in chapter 4 will give a good indication of those plants that can be used in areas that will not be continually inundated. The ponding times, shown in days under Ponding, will give a good indication of what zones of the wetland the species should be planted. Shown below in Table 2.2 are those plants that should do well when planted within the normal, permanent pool of the wetland.

Wild Rice Table from: Design of Storrnwater Wetlands Sys tems: guidelines for creating diverse and effective stormwater wetlands in the mid Atlantic BI "ion Schueler 2.7 Design Requirements for Pocket Wetlands In those situations where a combination of stormwater BMPs will be utilized to achieve the required 85% TSS removal, pocket wetlands in combination with grassed swales or filter strips can provide the needed removal. For design purposes these can be thought of as a special case of the extended detention wetland, or possibly a small wet detention pond with special emphasis placed on the wetland plantings. The sizing process should follow that of the wet detention basin, but with the following table (Table 2.3) used in place of Table 1.1. For example, a development of 4.5 acres, with 3.825 acres of imperviousness (85% imperviousness) would need a pocket wetland that. had 0.96% of 4.5 acres of permanent pool. One notable difference between this table and Table 1.1 is that no depths are given. An average depth of two feet is assumed. 19 O?O? W AT ?9QG DEW -{ Michael F. Easley, Governor William G.

The purpose of this project is to provide necessary administrative facilities to keep pace with the growth of Dare County, and will be constructed on county-owned land next to the existing Dare County Justice Center building. Mulkey Engineers & Consultants (Mulkey) have been retained by Heery International and Dare County to provide engineered stormwater design plans and Section 401/404 permitting assistance. The questions raised in your email sent on July 7, 2006 to Sharon Barnett of the United States Army Corps of Engineers (USACE) specifically deal with stormwater issues. Mulkey feels confident that the proposed stormwater design plan that has been generated will adequately and efficiently treat all stormwater entering the site prior to its release downstream. Several stormwater management devices (including LID technologies) have been integrated into the overall site plan including, pervious pavement, grassed swales, shallow bioretention basin, and a wet detention pond. It should be noted that the stormwater plan for this proposed project has not been formally approved by the North Carolina Division of Land Resources or the North Carolina Division of Water Quality. For this site, pervious pavement will be utilized to reduce stormwater runoff and provide treatment for a large portion of the proposed parking area. Adequate permeability of the sub-grade soils (loamy sands) inherent to the coastal region, makes this site suitable for use with the pervious pavement system. Utilizing pervious pavement will aid in reducing the percent of imperviousness calculations for the built-upon-area. Dependent upon the actual gravel base installed beneath the pervious pavement, up to a 60% reduction in stormwater runoff can be achieved, which reduces the amount of runoff flowing into downstream treatment devices. In addition, while pervious pavement will not receive direct credit for pollutant removal, credit is received for reducing the percent impervious area, which reduces the pollutant loads for the site. The areas of pervious pavement will be located between the regular impervious pavement and die bioretention areas. For intermediate stormwater treatment, grassed swales will be incorporated into two of the parking islands. Stormwater will flow directly into the shallow swales by eliminating MULKEY INC. 6750 TRYON ROAD CARY, NC 2751 1 PO Box 33127 RALEIGH, NC 27636 PH: 919-651-1912 FAX: 919-651-191 B W W.MULKEYINC.COM August 16, 2006 Citizens for Responsible Water Management Mr. James Marple Page 2 the curb and gutter on the upstream side. Due to the more permeable soils located on the coast, additional benefit is gained by the greater infiltration rates. While used by itself, grassed swales do not provide 85% total suspended solids (TSS) removal, but used in series with an extended dry detention pond dle required TSS removal is achieved. However, the TSS removal on the proposed site is even larger due to the fact that the grassed swales will be used in series with a wet detention pond to provide final treatment of the stormwater. Also being installed in series with the wet detention basin in the east parking lot is a shallow bioretention basin. This type of LID device provides infiltration and a 6" deep pond of water storage for absorption by the dense vegetation located throughout the basin. Infiltration is aided by the layers of sand, organic layer/mulch, and planting soil on top of the existing permeable soils. To the extent that the water is unable to infiltrate the basin, a yard inlet is placed at the back in order to convey the surplus runoff to the downstream wet detention basin, which will provide further pollutant removal. This bioretention basin is designed to handle only the first inch of runoff; however, all water will be collected and conveyed to the wet detention basin. The final step in the series of stormwater control devices is the wet detention basin. The purpose of this device is to: v provide supplementary pollutant removal from the runoff that has already passed through the grassed swales or the bioretention basin, o pollutant removal for runoff that has not passed through any treatment device (roof drains), O and control the design runoff volume from the 10-year storm. The wet detention basin has been designed to provide stormwater treatment for all of the new impervious area without taking credit for the pervious pavement, grassed swales, and bioretention basin. This will allow for a greater stormwater treatment capability than what is typically required on a site of this size. The pond is designed with a forebay, which acts as a settling basin for the incoming stormwater flow. After passing through a weir at the head of the primary impoundment, water enters the permanent water quality pool. The pool depth is three feet, which allows settling of smaller particles as well as pollutant removal. In addition, the pond incorporates a temporary water quality pool which controls the runoff from the 3" rainfall to aid in the settling of any suspended solids. It is important to note that the proposed wet detention basin is nearly three tunes the size required by North Carolina water quality guidance (required volume =10,625 ft3 vs. proposed volume = 27,389 ft3). Used alone, each of these stormwater devices, except for die wet detention basin, can not provide the essential infiltration, detention, and pollutant removal that is required for any construction project. However, the stormwater plan for this site makes use of all these devices in series which provides far greater benefits in each of these areas. This is particularly important given the close proximity of the surface waters to the surrounding wetlands. Furthermore, the placement of the grassed swales and a bioretention basin in the August 16, 2006 Citizens for Responsible Water Management Mr. James Marple Page 3 interior of the parking area improves the aesthetics of the site by diminishing the appearance of a mass paving lot that are seen on so many other locations.

Location The project is located on the northwestern corner of the intersection of United States Highway 64 East and United States Highway 64 Business in Manteo, Dare County, North Carolina. Existing Site Conditions The existing jurisdictional wetlands on this property have been disturbed in the past by clearing and mowing. The predominant tree layer consists of scattered stands of Loblolly Pine (Pinus taeda). Understory vegetation is regularly mowed and consists of Salt Meadow Cordgrass (Spartina patens), Common Greenbriar (Smilax b071a-110x), Cattail (Typhus spp.) and Poison Ivy (Toxicodendron radica71S). Applicant's Stated Purpose The applicant's stated purpose of the project is to construct a building that will consolidate county administrative operations, increase efficiency by moving all county administrative functions into one building, and reduce overall cost to the county operations budget. Project Description The proposed project involves the construction of an administrative building and associated parking lot/access in conjunction with the existing Dare Justice Center building on the adjacent property. The construction of the administrative building will permanently impact approximately 0.95 acres of jurisdictional wetlands. Other Required Authorizations This notice and all applicable application materials are being forwarded to the appropriate` State agencies for review. The Corps will generally not make a final permit decision until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives State certification required by Section 401 of the Clean Water Act (PL 92-500). The receipt of the application and this public notice in the NCDWQ Central Office in Raleigh serves as application to the NCDWQ for certification. A waiver will be deemed to occur if the NCDWQ fails to act on this request for certification within sixty days of the date of the receipt of this notice in the NCDWQ Central Office. Additional information regarding the Clean Water Act certification may be reviewed at the NCDWQ Central Office, 401 Oversight and Express Permits Unit, 2321 Crabtree Boulevard, Raleigh, North Carolina 27604-2260. All persons desiring to make comments regarding the application for certification under Section 401 of the Clean Water Act should do so in writing delivered to the North Carolina Division of Water Quality (NCDWQ), 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 Attention: Ms Cyndi Karoly by July 27, 2006. The applicant has not provided to the Corps, a certification statement that his/her proposed activity complies with and will be conducted in a manner that is consistent with the approved North Carolina Coastal Zone Management Program. Pursuant to 33 CFR 325.2(b)(2), the Corps can not issue a permit for the proposed work until the applicant submits such a certification to the Corps and the North Carolina Division of Coastal Management (NCDCM), and the NCDCM notifies the Corps that it concurs with the applicant's consistency certification. Essential Fish Habitat This notice initiates the Essential Fish Habitat (EFH) consultation requirements of the Magnuson-Stevens Fishery Conservation and Management Act. The Corps' initial determination is that the proposed project will not impact EFH or associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management Councils or the National Marine Fisheries Service. This determination is based on the absence of any estuarine or marine areas within the proposed project area. Cultural Resources The Corps has consulted the latest published version of the National Register of Historic Places and is not aware that any registered properties, or properties listed as being eligible for inclusion therein are located within the project area or will be affected by the proposed work. Presently, unknown archeological, scientific, prehistoric, or historical data may be located within the project area and/or could be affected by the proposed work. Endangered Species The Corps has reviewed the project area, examined all information provided by the applicant and consulted the latest North Carolina Natural Heritage Database. Based on available information, the Corps is not aware of the presence of species listed as threatened or endangered or their critical habitat formally designated pursuant to the Endangered Species Act of 1973 (ESA) within the project area. A final detennination on the effects of the proposed project will be made upon additional review of the project and completion of any necessary biological assessment and/or consultation with the U.S. Fish and Wildlife Service and/or National Marine Fisheries Service. Evaluation The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity on the public interest. That decision will reflect the national concern for both protection and utilization of important resources. The benefit which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. All factors which may be relevant to the proposal will be considered including the cumulative effects thereof; among those are conservation, economics, aesthetics, general environmental concerns, wetlands, historic properties, fish and wildlife values, flood hazards, flood plain values (in accordance with Executive Order 11988), land use, navigation, shoreline 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.

This project will provide necessary administrative facilities needed to keep pace with the growth of Dare County, and will be constructed on existing county-owned land next to the existing Dare County Justice Center. Funding for the project is being provided by the county and the state. Introduction The specific goal of the construction is to build a high quality administrative facility for the people of Dare County. The project will create a self-contained and cost-effective government facility in an environmentally sensitive and well-planned manner. The new building will be located nett to the county's justice Center building. The Justice Center is owned by Dare County and was constructed in 2001-2002 to provide modern facilties and significantly more space for courthouse proceedings. The property is located within the zoning jurisdiction of the Town of Manteo. Mulkey, Inc. (I\iulkey) has been retained to provide land development design and Section 404/401 permit application services. Both Dare County and the Town of I\Ianteo have included development of a County government complex in their development and planning documents, as a way to address future growth and demand for services. Further information concerning this proposed project is provided in the Environmental Assessment (EA) document, dated November 1, 2000, which was previously submitted to the North Carolina State Clearinghouse and for regulatory agency review. A Finding of No Significant Impact (FONSI) was completed in early 2001. The EA considered both the existing Dare CountyJustice Center and future outbuildings that include this proposed project. A reevaluation of the existing jurisdictional wetland areas on the subject property was approved by the United States Army Corps of Engineers (USACE) on June 28, 2005. The North Carolina Division of Coastal Management (NCDCI\I) has declined jurisdiction over the wetlands and surface waters within the proposed project area. A copy of the 2000 EA, 2001 FONSI and the 2005 JD are MULKEY INC. 6750 TRYON ROAD CHARY. NC 27511 PC Box 331 27 RALEIGH. NC 27636 PM: 91 9-851-1912 FAx: 919-051-1918 WWW.MULKEYINC.COM June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 2 included in Appendix A. Purpose and Need The plan to expand of the county facilities was developed in response to the forecast need for consolidated county administrative operations, the desire to increase county efficiency, and to reduce overall cost to the county operations budget. Proposed site uses include expansion of the current administration facilities and the eventual construction of additional county buildings and associated parking. The purpose of the proposed project is to construct an administrative building associated with the existing Dare County Justice Center building. This project will be located on county property adjacent to the existing courthouse building. At present, some county employees are still utilizing older, disjunct county buildings located throughout the county, primarily in Manteo. This proposed construction would further alleviate problems with communication between different county agencies and employees to make for a more effective work environment. It would also continue to move all of the county service employees to one location, which is the future goal of the Dare County planning department. Water Resources Wetland delineations were originally completed for this project and subsequently approved by the USACE in March 1999. The delineation boundaries were recertified by the Corps during a field meeting held June 28, 2005. The project is located in Pasquotank River subbasin 03-01-51 and USGS 8-digit hydrologic unit 03020105. No streams are located within the project area; however, there is a large culvert beneath US Highway 64 which hydrologically connects the wetland areas on the project site to wetlands on the opposite side of the highway to the south. These wetlands eventually drain into tributaries and marsh land associated with Roanoke Sound. Surface water resources in the vicinity of the subject property include Shallowbag Bay (Class SC waters) to the north, the Roanoke River (Class SC waters) to the east, and Croatan Sound (Class SA waters) to the west. There are three areas of 303 (d) waters in the vicinity of the project study area, the Roanoke Sound from Shallowbag Bay to Johns Creek approximately 1.5 miles east of the project area, Sandbeach Creek approximately 1.5 miles southeast of the project area, and the Roanoke Sound at Mill Landing approximately 1.5 miles south of the project area. The existing jurisdictional wetlands on this property were significantly disturbed in the past by extensive clearing. These areas are best classified as bottomland hardwood wetlands as they were once part of the bottomland hardwood wetlands to the south prior to the construction of US 64. The National Wetlands Inventory (NWI) classification is palustrine saturated forest (PFO). June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 3 Permanent Impacts: Project construction will create a total of 0.95 acres of permanent fill in jurisdictional wetlands. These impacts are shown on the attached Wetland Permit Impact Summary Table and permit design drawings. Avoidance, Minimization, and Compensatory Mitigation Section 404 of the Clean Water Act requires regulation of discharges into Waters of the United States (U.S.). Surface waters, including lakes, rivers, and streams are subject to jurisdictional consideration under the Section 404 program. Wetlands are also identified as Waters of the U.S. Avoidance, minimization, and compensatory mitigation are considered in sequential order when addressing impacts to Waters of the U.S. Avoidance and minimization measures were incorporated during the project planning and National Environmental Policy Act (NEPA) compliance stages as noted in the following sections. Avoidance: The natural resources of the project site have been carefully used in planning for this primary and driving use for the success of the proposed project. The facilities have been designed to incorporate and enhance the natural resources of the site. The wetlands are so extensive throughout the subject property that impacts to these areas cannot be avoided except by choosing a no-build alternative. Undisturbed wetlands located near the intersection of Marshall Collins Drive and US 264 Business will remain undisturbed and will be avoided. Other adjacent tracts of county-owned land have been previously placed into permanent conservation easements and will be avoided. The project as planned avoids impacts on natural resources to the maximum extent practicable. Avoidance of impacts on wetlands was a central effort in the many considerations of infrastructure and facilities designs. The land plan, roads, utility corridors, and other developmental aspects of the proposed project were all planned after the wetlands were thoroughly investigated. 1\Iinimi7ation: Wedand impacts from the proposed building construction have been minimized to the extent possible by aligning the building, parking lot, and associated stormwater ponds to take advantage of the greatest amount of upland on the property. In addition, a large retaining wall is planned for die southern edge of the building and parking lots site to minimize the amount of wetland fill in these areas. Without this retaining wall nearly all of these wetlands would need to be impacted by fill slopes in order to bring the proposed construction to the required flood zone elevation. Project-specific measures will be employed to minimize impacts to Waters of the U.S. during project construction. All practicable means will be employed to minimize wetland impacts due to runoff, sedimentation, or other construction activities. Best Management Practices (BlAIPs) will be strictly enforced to control sedimentation during project construction. Clearing and grubbing activities will be minimized where possible and vegetation will be reestablished on exposed areas with judicious pesticide and herbicide management. Appropriate measures will be taken to avoid spillage of construction materials and provisions will be made for storing and handling waste materials in a manner that prevents materials from entering the streams or wetlands. June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 4 Compensatory Mitigation: Dare County has proposed to pay into the North Carolina Ecosystem Enhancement Program (NCEEP) for all wedand impacts proposed for this project. These impacts will be paid for at a 2:1 ratio. In a letter dated May 3, 2006 (attached) the NCEEP has agreed to provide in-lieu-fee mitigation for this project. Utilities Utility relocation is not anticipated with this project; however, water and sewer connections will be included. Any environmental impacts from future utility relocations will be the responsibility of the individual utility companies. The utility companies with services located in the project vicinity include Eastern North Carolina Natural Gas Company, Charter Communications, Dominion North Carolina Power, Sprint, Dare County Water Department, and the Town of Manteo Waste Water Treatment Plant. A water line connects to the courthouse building from US 64 Business along Marshall Collins Drive, and a sewer line force main that runs along US 64 bypass, connects to the courthouse on the western side of the building. FEMA Compliance The entire site is located within a designated Federal Emergency Management Agency (FEMA) flood zone, Zone A6 (Nfap # 3753480220C, February 19, 1986). Appropriate actions are being considered in the design of the proposed building to meet or exceed elevation standards for buildings within the flood zone. Indirect and Cumulative Impact Analysis Existing rules for the 401 Water Quality Certification Program (15A NCAC 2H.0506(b)(4)) requires the NCDWQ determine that a project "does not result in. cumulative impacts, based on past or reasonably anticipated future impacts, that cause or will cause a violation of downstream water quality standards." A copy of the Indirect and Cumulative Impact Study is included in Appendix A. As noted in Section 3 of the EA document, existing land uses near the property are primarily undeveloped forest land to the north, west, and south. East of the subject property beyond Business Highway 64 is low-density residential and commercial development. The nearest residential properties to the proposed Administrative Services building are approximately 0.25 mile north of the building site. Proposed future construction activities include the construction of an additional county services building along US 264 Business near the current location of the Dare County Alcohol Beverage Control (ABC) store. In addition, wetland remediation activities are planned for the wetland areas immediately south of the proposed building (between US 64 and the proposed building site). These wetlands have been significantly disturbed in the past from clearing, grubbing, digging, and mulching activities. A future remediation project June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 5 would serve to make these wetlands functional again and provide for wetland education opportunities. Cultural Resources The EA document indicated the North Carolina State Historic Preservation Office (SHPO) found no documented historic properties within the project study area or in the immediate surrounding areas that would be impacted by the proposed project. There has been no change in structures since the 2000 EA. Essential Fish Habitat The 1996 amendments to the Magnuson-Stevens Fishery Conservation and Management Act (NISFCI\iA) set forth a new mandate for the National Marine Fisheries Service (NMFS), regional fishery management councils (FMCs) and other Federal agencies to identify and protect important marine and anadromous fish habitat. The Essential Fish Habitat (EFH) provisions of the MSFCI\iA support the Nation's overall marine resource management goals - maintaining sustainable fisheries. The FMCS, with assistance from the NNIFS, have delineated "essential fish habitat" for managed species. Essential Fish Habitat is defined in the hiSFCIAiA as "those water and substrate necessary to fish for spawning, breeding, feeding or growth to maturity." According to the proposed master plan associated with the government center expansion, no estuarine areas exhibiting seagrass, creeks, mud bottoms or estuarine water columns, or marine areas will be adversely impacted as a result of construction. Federally-Protected Species Federal law requires that any federal action likely to adversely affect a species listed as federally protected be subject to review by the U.S. Fish and Wildlife Service (USFWS) or National Marine Fisheries Service (NMFS) (under the provisions of Section 7 of the Endangered Species Act [ESA] of 1973, as amended). Prohibited actions which may affect any species protected under the ESA are outlined in Section 9 of the Act. Other species may receive additional protection under separate laws such as the Lacey Act Amendments of 1981, the Migratory Bird Treaty of 1999, the Marine Mammal Protection Act of 1972, or the Eagle Protection Act of 1940. North Carolina Natural Heritage Program (NCNHP) maps were reviewed in May 2005. The March 9, 2006 USFWS list of federally protected species for Dare County, North Carolina lists eight Endangered species and six Threatened species. The building site consists of cleared land wide three small borrow ponds adjacent wetlands and a few young loblolly pine (Pines taeda) trees throughout. The subject property provides suitable habitat for the American alligator, glossy ibis, little blue heron, snowy egret, tricolored heron, star- nosed mole, and Carolina glasswort. This suitable habitat is generally located within the marsh and wetland areas. None of these species were observed during the field investigations. A review of NCNHP records in May 2005 revealed no federally or state listed species within one-mile of the project study area. Therefore, this project will have no June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 6 impact on protected species. Table 1 in the Appendix depicts the federal and state protected species listed for Dare County and their status. Adjoining Property Owners A review of the property parcels adjacent to the County's Justice Center Building determined that there are 11 adjacent properties to the project site. The surrounding area contains residential, commercial, and undeveloped properties. There are three residential properties located near the northern corner of the site. There are two undeveloped properties to the north and east of the subject property, and a vacant lot to the west between commercial and residential properties. There are four commercial properties to the west, two office buildings, a pharmacy, and an auto parts store. The North Carolina Department of Transportation (NCDOT) owns a substantial amount of right-of-way associated with US Highway 64 to the south of the subject property, and a smaller amount of right-of-way to the east associated with US Highway 264 Business. The state of North Carolina also owns the undeveloped forest land beyond US Highway 64 to the south. Table 2 lists the adjoining properties, the owner name, and owner addresses. The property numbers correspond to the property locations shown on Figure 3 (Appendix).

This document is meant as an addendum to the original Environmental Assessment (EA) document, Section E "Predicted Environmental Effects of Projects." Study Area The purpose of this indirect and cumulative impact summary is to provide an assessment of the effects the proposed project will have on natural resources in the watershed surrounding the project area. The Council on Environmental Quality describes indirect impacts as those "that are caused by the action and are later in time or farther removed in distance, but are still reasonably foreseeable" (40 CFR 1508.8). Cumulative effects, are "impacts on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (federal or nonfederal) or person undertakes such other actions" (40 CFR 1508.7). The area studied for this assessment is generally Dare County's jurisdictional boundaries, specifically the central portion of Roanoke Island where the project site is located. This watershed area is included in U.S. Geological Survey (USGS) hydrologic unit 03020105. The surrounding area contains low-density residential and commercial properties, with undeveloped foresdand and marshland throughout. The property currently supports the existing Dare County Justice Center, which houses the county tax offices, Register of Deeds, Sheriffs office, holding cells, five courtrooms, and Clerk of Court offices with support facilities. The future plans for the property is to centralize all of the county services to a central location with acceptable transportation access. Documentation and Background Information The following documents are incorporated as supporting documentation and as references for this assessment. They are: Dare County Justice Facility, an Analysis of Alternatives (August 2000): The review process included assessments of available properties on Roanoke Island that are sufficient in area for the project, associated environmental impacts, cost of the available properties, traffic flow and potential congestion at the sites reviewed, accessibility to the courthouse by all citizens of Dare County, safety issues related to transportation of prisoners by law enforcement officers to the facility and associated security for attorneys, judges, and courthouse personnel. • Draft Roanoke Island Transportation Plan: The purpose of this plan was to develop a transportation plan that identifies potential transportation projects for short-term, mid- term, and long-term conditions. As a planning level document, this transportation plan for Roanoke Island establishes the general guidance and direction for the future transportation network on Roanoke Island. Natural Resources Natural resource investigations were conducted by Mulkey, Inc. (Mulkey) personnel in May 2005 for the proposed project Quible & Associates conducted previous wetland delineations on the subject property and a formal jurisdictional determination re-verification was approved by the USACE for the site on June 28, 2005. Potential for Indirect and Cumulative Effects According to guidance developed for assessing indirect and cumulative impacts caused by implementation of building projects, several factors are taken into consideration when evaluating the potential for impacts. The following is an assessment of these factors as they relate to the proposed project • Conflict with Local Plan As previously discussed, the proposed project is consistent with local and regional planning and is included in Dare County's planning documents. It is not in conflict with any local or regional land use plans or zoning. • Explicit Economic Development Purpose The purpose of this project is to provide additional office and conference space for various existing county services. • Stimulation of Complimentary Land Development Stimulation of complimentary land development is most likely to occur when projects are located near undeveloped sites. Complementary development can occur in either urban or suburban areas, and is more likely to be associated with a greater proportion and mix of higher density uses. Since this is merely an addition to the existing Dare County Justice Center complex little off-site development is anticipated to occur from the construction of this project The majority of the development that has occurred since the original Dare Justice Center was completed in 2002 has been the result of the recently constructed 4-lane US Highway 64 bypass of Manteo. 2 • Notable Features in the Project Area Jurisdictional wetlands are found throughout the proposed construction site. These resources are described in the attached cover letter report Efforts have been taken to avoid and minim;7e the impacts to wetlands as much as feasible. The layout of the building and associated parking were oriented so as to use the greatest amount of non-wetland acreage. Also, a retention wall will be constructed on the south side of the proposed building to significantly minimise wetland impacts. Analysis of Indirect and Cumulative Impacts This analysis is by necessity a brief overview of potential impacts to natural resources from indirect and cumulative effects. A summary of the indirect and cumulative effects analysis indicates the following. • Growth trends indicate that Dare County, the Town of Manteo, and surrounding areas are continuing to grow, driven primarily by a tourism industry found throughout coastal communities. All community services are then by necessity needed to grow to meet the demands of the population. This proposed Administrative Services building will serve to provide current and future needs for county services from its citizens. • The undeveloped land surrounding the Dare County site will likely remain undeveloped due to significant wetland and coastal acreages and because it is land-locked with no roadway access available. In addition, a substantial portion of the surrounding undeveloped land has been placed into a permanent conservation easement from the construction of the original Dare County Justice Center building. • Local changes in zoning designations or land use are not anticipated as a result of this project The surrounding area is zoned for residential and commercial development, which will potentially create more impervious surface per acre than existing levels. This could lead to increases in surface water runoff from these surfaces; however, this project is not anticipated to spur this growth. • The project area contains both wetland and non-wetland areas that have been significantly disturbed in the past from clearing, grubbing, digging, and mulching activities. The wetlands are not fully functioning and are not high quality. Therefore, these communities are not unique and provide wildlife habitat primarily to those species that have adapted well to man-dominated or altered communities. • Due to the distance from the Roanoke or Croatan Sounds, water quality degradation is not anticipated from the construction of the proposed administrative building. Strict adherence to all federal, state, and local regulations during construction will help ensure that the surface waters are not negatively impacted or that impacts are minimal • The potential does not e?:ist for private residences to transition to businesses due to implementation of this project • The consequences of potential ecological effects are expected to be minor since the project site is in a suburban area. With proper adherence to regulations, it is anticipated that this project will not produce substantial changes in the ecological makeup of the study area; therefore, the consequences of such effects are expected to be minimal. Mitigation of Indirect and Cumulative Impacts Several layers of federal, state, and local regulations and ordinances designed to protect the natural environment, and water quality in particular, already exist All development projects, whether completed by Dare County or other entity, must follow these guidelines in order to mitigate potential indirect and cumulative impacts. The regulations and programs listed below are not intended to be definitive or restrictive. New rules and regulations may be promulgated in the future that will provide additional levels of environmental protection. Federal and State Regulations Clean Water Act: Section 404 and Section 401. These programs regulate impacts to jurisdictional surface waters, including streams, wetlands, and certain impounded waters. All private and public construction activities must obtain applicable permits and certifications prior to commencing work that will affect these regulated resources. Primary components of the 404 and 401 programs is the requirement for avoidance and minimization of impacts before the agencies consider permit applications. • Clean Water Act: Section 303(d). Waters identified by the State as not supporting the intended uses must be identified on a statewide list of impaired waters. Water pollution sources must be identified and the total maximum daily limits (nfDL) of pollutants allowed must be allocated among the permitted dischargers. • Clean Air Act: The subject property is located in an area classified as a "complete attainment" area by the North Carolina Department of Air Quality. The air quality is expected to remain within allowable pollutant levels. • Endangered Species Act of 1973: Protects and conserves natural habitats of species that have been listed by the US Fish and Wildlife Service (USFWS) as threatened or endangered. • National Flood Insurance Program (NFIP): Protects stream riparian areas and wetlands, as well as water quality, by restricting floodplain development Dare County and the Town of Manteo flood protection program meets or exceeds requirements of the non- regulatory national program. • National Pollution Discharge Elimination System (NPDES): Stormwater discharges controlled by NPDES are regulated by NCDWQ's Phase I and Phase II permit program. Under the Phase II program, local governments are required to implement measures for reducing and managing stormwater. 4 North Carolina Archaeological Resources Protection Act (NCARPA): Archaeological resources on private or public lands are protected under NCARPA, the Unmarked Human Burial and Human Skeletal Remains Protection Act, the North Carolina Archeological Record Program, the State Environmental Protection Act, and other federal laws. The USACE requires an archeological review for projects needing a Section 404 permit. North Carolina Sedimentation and Pollution Control Act Land disturbing activities such as construction projects must install and maintain adequate sediment control measures that prevent sediment from entering streams. The NC Division of Land Resources regulates construction activities by requiring application for a sediment and erosion control permit. • North Carolina Clean Water Management Trust Fund: A non-regulatory program that was created to address water quality problems by eliminating pollution, protecting and conserving unpolluted surface waters, and establishing riparian buffers. Conclusion It is reasonable to conclude that construction of the proposed Administrative Services building will not increase ecological impacts beyond those expected from current and future development plans for the region. The federal, state, and local regulations and ordinances that currently exist adequately provide protections for the natural environment and provide controls to limit indirect and cumulative impacts. FINDING OF NO SIGNIFICANT IMPACT Environmental Assessment for the Dare County Justice Facility Dare County February 15, 2001 An environmental assessment (EA) has been prepared pursuant to the requirements of the North Carolina Environmental Policy Act for the proposed Dare County Justice Facility. A new courthouse will be constructed on Roanoke Island in Dare County. This courthouse will consist of a two story primary building with two smaller out buildings and approximately 5 acres of parking facilities. This facility will consolidate services related to judicial matters into a facility that will better serve the needs of the County citizens. This project will be located on Roanoke Island in eastern Dare County. The abundance of wetlands on the 80-acre site presented a challenge for this project, however, the issues have been resolved. Approximately 60 acres are designated as wetland areas requiring a federal permit. In addition a wetland mitigation plan was required. The water resources of the region include surface waters in streams and drainageways and groundwater. None of the water resources of the region are likely to be impacted as a result of this project. There are no shellfish leases within the vicinity of this site. Air quality and noise levels may be impacted during the construction phase of this project, but the impacts are not likely to be long- term. A detailed "alternatives analysis" was conducted to evaluate the best location for the new justice facility. The "alternatives analysis" looked at numerous sites as well as renovating the existing courthouse in Manteo. The final location presented in the Environmental Assessment was chosen as it met all requirements needed to consolidate judicial activities into a centralized location. Mitigative measures will be incorporated into the project to reduce or eliminate further environmental impacts. These include providing mitigation at the rate of 20:1 for impacts to existing wetlands. 2.73 acres of wetland are anticipated to be affected by this project; hence, Dare County has also agreed to purchase mitigation credits at a ratio of 2:1 in an approved mitigation bank or by direct payment to an appropriate conservation fund. In addition, stormwater management facilities will be in place to minimize impacts of runoff. Based on the findings of the EA and on the impact avoidance/mitigation measures contained therein, it is concluded that the proposed project will not result in significant impacts to the environment. This EA and Finding of No Significant Impact (FONSI) are prerequisites for the issuance of the permit actions by the Division of Water Quality. Pending approval by the State Clearinghouse, the environmental review for this project will be concluded. An environmental impact statement will not be prepared for this project. Division of Water Quality February 15, 2001 Email communications concernin! the EA and FONSI Cindy, If I recall that FONSI is less than five years old. Provided the new building was considered in it and no changes are proposed to what the FONSI authorized, the project can proceed to permitting. Please attach a copy of the FONSI to the permit application.

ENVIRONMENTAL ASSESSMENT DARE COUNTY JUSTICE FACILITY ROANOKE ISLAND, DARE COUNTY, NORTH CAROLINA A. PROPOSED PROJECT DESCRIPTION Dare County has proposed to construct a new justice facility on Roanoke Island. The site selected for the courthouse is an approximately 80.64 acre tract of land located 1/8th of a mile northwest of the US 64/264 junction with NC 345 (at approximately 35" 53'22"N, and 75° 39' 41"W) on Roanoke Island, Dare County, North Carolina. Attachment A depicts the project -> location on a Site Location/Topographic Map. Attachment B presents the proposed justice facility and associated buildings, drive, and parking area, and areas of impact to wetlands. Specifically, the proposed project includes a two-story 35,112 square foot primary building with two out-buildings. Parking for the facility surrounds the buildings and covers a total of 208,646 square feet. Stormwater retention basins will be constructed as part of the overall development. The total impermeable coverage associated with the project is 284,316 square feet. Some grading and infrastructure construction will occur in wetlands. An approved Section 404 wetlands delineation for the subject property is included as Attachment C. The project site was selected following an analysis of alternative properties performed by Quible & Associates and the Dare County Capital Improvements Committee. This analysis is entitled Dare County Justice Facility, an Analysis of Alternatives, and is provided as Attachment D. The review process included assessments of available properties on Roanoke Island that are sufficient in area for the project, associated environmental impacts, cost of the available properties, traffic flow and potential congestion at the sites-reviewed, accessibility to the courthouse by all citizens of Dare County, safety issues related to transportation of prisoners by law enforcement officers to the facility and associated security for attorneys, judges and courthouse personnel. Also considered were surrounding property uses which might tend to detract from the courthouse and other aesthetic and visual considerations that would impact a facility that will be a long standing symbol of Dare County government. Following review utilizing all the parameters described above the subject tract was selected as superior to the other available alternatives. Following the site selection process, Dare County authorized Heery Architects and Quible & Associates, P.C. (Quible) to develop a preliminary design for the Courthouse utilizing the subject tract. The enclosed plan view of the project has been prepared with coordination and input from the Dare County Commissioners, Dare County Manager, Dare County District Attorney, Dare. County Sheriffs Department and presiding Judges that will hold court in the new facility. The proposed project at build out includes a total of 284,316 square feet. (6.53 acres) of impervious surface with approximately 118,919 square feet (2:73 acres) of that total located within Section 404 wetlands. A numerical breakdown of the proposed development and impacts is found on the enclosed plan view plat. The configuration of the courthouse complex has been manipulated by Quible and Heery to maximize use of the available uplands on the parcel and development within wetlands represents unavoidable impacts given the minimum requirements for the master plan developed. The project will be served with central sewer from the Town of Manteo and potable water is provided from the central Dare County system. Page 1 of 10 B. PURPOSE AND NEED FOR PROPOSED PROJECT Currently, Dare County government buildings with services related to judicial matters are located in separate buildings at a number of locations on Roanoke Island. There have been three separate studies in 1994, 1995 and 2000 concerning alternatives for improvements in that system and to analyze requirements related to the size, location, traffic flow, parking requirements and infrastructure requirements for renovation of the existing courthouse or for construction of a new facility. The County also identified a need for governmental services such as the tax office, clerk of court, registrar of deeds, law enforcement, court rooms, and other administrative buildings to be located in proximity to each to better serve the citizens of the County. The studies further indicated that a facility of approximately 70,000 sq. ft. with 400 parking spaces will be required to provide the combined services described above, and in more detail in the Alternatives Analysis included as an attachment to this EA. C. ALTERNATIVES ANALYSIS A comprehensive Alternatives Analysis is included at Attachment D. A summary of the comprehensive analysis revealed the following as the most reasonable alternatives if the proposed project was not permitted. No Action If a new judicial facility is not constructed then the problems that have been identified since the 1980's will continue to exist. (Note: See enclosed Attachment D outlining status of courthouse and associated administrative buildings prepared in 1984 by NCSU School of Design; Also enclosed is a March 30, 1998 letter from the Dare County Grand Jury to=the Dare County Board of Commissioners outlining deficiencies in operation and physical conditions associated with the current courthouse based on their use of the facility. Based on the referenced studies, and the continued growth of the case load that is occurring in Dare County, it is the position of the Dare Commissioners that continued use of the current facility is short sited and unacceptable. Renovation of Existing Courthouse A review of requirements for the renovation and expansion of the existing courthouse has identified two major problems. First, the existing courthouse, which was completed in 1904 has been calculated to contain 5,274 square feet of usable space on two floors. The courthouse is located on a small tract of land in the center of downtown Manteo with paved streets on three sides. The surrounding area is completely developed and therefore the opportunity to expand the facility either vertically or horizontally sufficient to meet current needs is extremely problematic. Secondly, parking in downtown Manteo has been at a premium for a number of years. Recently, the construction of new retail facilities and the expansion of the Roanoke Island Festival Park have made the traffic and parking problems even worse. No solution to the parking problems that would be created by the expansion of the courthouse has been identified short of removing existing buildings for the purpose of constructing required parking. Therefore, the renovation of the existing facility is considered impractical because it would create problems with traffic and parking downtown. For this reason the county has rejected this approach. Page 2 of 10 D. EXISTING ENVIRONMENTAL CHARACTERISTICS OF PROJECT AREA 1. Topography- The natural topography of the subject site is relatively level with a gentle slope toward the west, in the direction of Croatan Sound. A man-made bermed area exists in the vicinity of the proposed justice facility, and also further west, in the location of a former borrow pit. The bermed areas are devoid of vegetation and used for dredge spoil containment. The top of the spoil containment berm represents the highest elevation of the subject site. 2. Soils- According to the Dare County soil survey, dated March 1992, the subject property contains Hobonny, Leon, Baymeade, Belhaven, and Johns soil series. Hobonny, Leon and Belhaven series are considered hydric and Baymeade and Johns are considered to be non- hydric. All of these series are sandy to loamy sand, except for the Hobonny series which is a fiberous to sapric muck. Areas that have been developed for dredge spoil placement may no longer exhibit the natural soil profile. Soil survey data is depicted on a soils map included as Attachment E. 3. Land Use- Currently, the subject site is used for on-site disposal of dredge spoil, or is undeveloped wooded, shrub/scrub wetlands or coastal marsh. Land to the east of the subject site is developed commercially along US 641264, and near the intersection of US64/264 and the new US 64/264 right-of-way. To the south of the subject site is the new US 64/264 right-of-way leading to the new Croatan Sound bridge. West of the subject site is the Croatan Sound. Adjacent property to the north of the subject site is undeveloped and wooded. The nearest residential land use occurs on the adjacent property to the northeast of the subject site. 4. Wetlands- 60.57 acres of wetlands exist on the 80.64 acre parcel. The "Section 404" wetlands are depicted on a map included as Attachment C. This wetland/upland line was delineated during 1998 and 1999 and verified by the United States Army Corps of Engineers by signature on March 15, 1999. These 404 wetlands consist of scrub/shrub and forested type systems that primarily a function as wildlife habitat. Coastal wetlands exist throughout the west and northwest areas of the site. These Juncus roemerianus dominated marshlands are under the jurisdiction of the North Carolina Division of Coastal Management. Through use of remote censing techniques, a total of 23.05 acres of coastal wetlands have been calculated on the site and can be viewed on Attachment F. These wetlands serve as wildlife habitat and also abate erosion during storm events. A comprehensive discussion of the wetlands upon the subject property, the proposed alteration of some of the wetlands for construction of the proposed facility, and compensatory mitigation proposed is included as a separate Wetland Mitigation Plan in Appendix 1. A site plat of the 80.64 acre parcel including impacted wetlands and proposed wetland mitigation area is represented as Attachment G. 5. Prime or Unique Agricultural Lands- The subject property contains marshland, wooded uplands, scrub/shrub wetlands or forested wetlands. None of the subject property is used for agricultural purposes. Page 3 of 10 6. Public Lands and Scenic, Recreational, and State Natural Areas- This subject property is privately owned by the Marshall C. Collins Family Limited Partnership. None of the surrounding properties are considered public lands or Scenic, Recreational or State Natural Areas. 7. Areas of Archaeological or Historical Value- A review of the subject property is being conducted by the Department of Cultural Resources at the Historic Preservation Office in Raleigh, North Carolina. According to the Eastern Office of Archives and History, the proposed site is not included as a zone of significant archaeological or historical value. 8. Air Quality- The subject property is located in an area classified as a "complete attainment" area by the North Carolina Department of Air Quality. The air quality is expected to remain within allowable pollutant limits. 9. Noise Levels- The subject property is currently used for placement of dredge spoil. Additionally, the new US 64/264 Croatan Sound Bridge right-of-way borders the property to the south. Current noise on the property is minimal, except that from the work on the DOT right-of-way and operations associated with the dredge process. 10. Water Resources- The subject site is located in the Pasquotank River Basin. Surface water resources in the vicinity of the subject site include Shallowbag Bay (SC waters) to the north and Croatan Sound (SA waters) the west. The two bodies of water are connected by an approximately 2.0 mile ditch. This ditch is influenced by wind tides and may flow in either direction. Groundwater use in the vicinity of the subject site includes supply wells within the Skyco Water Plant Wellhead Protection area. These wells are developed within Quaternary deposits to a depth of approximately 250 feet. This zone is characterized by sediments deposited since the end of the Pliocene and includes interbedded layers and lenses of sand silt clay and mollusk shell. Ten wells are located in this area. Well installation records confirm the location, stratigraphy, hydrology and depth of each well. Recharge to this aquifer system is through precipitation infiltration through the soil zone. 11. Forest Resources- The subject property contains marshland, wooded uplands, scrub/shrub wetlands or forested wetlands. A comprehensive discussion of the vegetative communities on the subject property is contained within the Wetland Mitigation Plan included as Appendix 1. 12. Shellfish, Fish and their Habitat- The ditch that passes through the subject property connects the Croatan Sound with Shallowbag Bay. Croatan Sound is classified as SA waters and Shallowbag Bay is classified as SC waters. The fisheries of Croatan Sound are utilized by local commercial and recreational users. Shellfish leases are not located in the Croatan Sound in the vicinity of the subject site according to the Resource Enhancement Section of the North Carolina Division of Marine Fisheries. The fishery quality of Shallowbag Bay is not as significant as the Croatan Sound, presumably due to the commercial nature of surrounding land use which may have had some impact on the health or productivity of the water, and is in fact closed to shellfish harvest due to Page 4 of 10 pollutants. The ditch that connects these two water bodies passes through the subject property. During the spring through fall this ditch contains juvenile fish species, especially in the west end, closer to Croatan Sound. 13. Wildlife and Natural Vegetation-Rare and protected species listed for Dare County can be found in Attachment H. According to the USFWS, federally protected endangered species listed for Dare County as of the February 28, 2000 listing include the kemp's ridley sea turtle (Lepidochelys kempii), hawksbill sea turtle (Eretomochelys imbricata), peregrine falcon (Falco peregrimus), red-cockaded woodpecker (Picoides borealis), roseate tern (Sterna dougalii) and manatee (Trichechus manatus). The Kemp's ridley, hawksbill and leatherback turtles are typically found in the open marine environment or on the beach when laying eggs, but may also enter the bays and sounds. These species and their habitat are not expected to be found in the project area. The peregrine falcon is a medium-sized raptor which nests on cliffs, river cutbanks, and trees; and hunts over open fields, waterways, and wetland areas such as swamps and marshes. The red-cockaded woodpecker is a small 20 to 22 cm (8 to 9 inch) wood boring bird found in open stands of mature pines. The roseate tern is a small black-capped bird with a deeply forked tail and black bill. It is a coastal species, found along salt bays, estuaries and oceans. The manatee is a large aquatic mammal found in both salt and fresh water in depths of 1.5 to 6 meters (5 to 20 feet) including canals, rivers, estuarine habitats, and saltwater bays. None of these federally listed endangered species have been reported on or within the vicinity of the Dare County Justice Facility site. Federally listed threatened species for Dare County include the loggerhead sea turtle (Caretta caretta), green turtle (Chelonia inydas), piping plover (Charadrius melodus), bald eagle (Haliaeetus leucocephalus), and the seabeach amaranth (Amaranthus pumilus). The loggerhead and green turtle are typically found at sea, but may also enter bays and sounds and may be found on beaches. The piping plover is a small 15 to 19 cm (6 to 7.5 inch) wading bird typically found on sand beaches and tidal flats. The bald eagle is a large raptor which nests in trees associated with coasts, rivers, and lakes. The seabeach amaranth is a monoecious annual herb with fleshy, roundish leaves, large fruits, and numerous branched stems. This reddish tinted amaranth is found on the upper beach and lower foredune of coastal barrier islands. None of these federally listed threatened species have been reported on or within the vicinity of the Dare County Justice Facility site. The red wolf (Canis rufus) is listed as experimental by the USFWS. Experimental species are treated as threatened on public land, for consultation purposes, and are proposed for listing on private land. The red wolf is a medium sized canid which inhabits any area of sufficient size that provides food, water, and thick vegetation for cover, including coastal prairie and marsh habitat. This species has been reintroduced into the Alligator River . National Wildlife Refuge. The American alligator (Aligator mississippiensis) is listed as threatened due to the similarity in appearance and habitat preferences to the American crocodile (Crocodylus acutus), which is listed as an endangered species nationally. The alligator is not considered to be threatened or endangered and is not protected under the Endangered Species Act. Preferred habitats include: rivers, streams, lakes, ponds, swamps, wetlands, Page 5 of 10 and other low water areas where fish, fowl and small animals provide an adequate food supply. Alligators are also known to inhabit ditches and drainage systems. Nesting sites include low, wet herbaceous areas where a mound is built and eggs laid. Incubation temperatures are provided by decomposing vegetation incorporated into the nesting mound. During field work in the project area, no alligators or crocodiles were found. No sightings near the project area have been reported to the NC Natural Heritage Program. A determination was therefore made that this project would have no effect on the American alligator or American crocodile. The black rail (Laterallus jamaicensis), rafinesque's big-eared bat (Corynorhimus rafenesquit7, and dune blue curls (Trichostema sp.) are listed as Federal Species of Concern (FSC) which may occur in Dare County. The black rail is a small 13 to 15 cm (5 to 6 inch) bird found in tidal marshes, grassy marshes and stubble fields. Rafinesque's big-eared bat is a medium-sized, long eared bat. Its preferred habitat is old growth forests and it is typically found in the coastal plain of North Carolina along river systems and other bodies of water. Dune blue curls are found on sandy and vegetated dunes, as well as in openings in maritime forests or shrub areas. None of these species were observed during visits to the subject site. Of all species with special Federal status, the Black Rail has the greatest potential to be located in the vicinity of the subject property. This species would most likely be found within the coastal marsh, and not directly in the project area. E. PREDICTED ENVIRONMENTAL EFFECTS OF PROJECTS 1. Topo ;raphy- The existing site conditions do not represent the natural topography of the region as large soil berms have been constructed on-site for dredge spoil placement. The topography of the subject site will be directly altered by the proposed project. Indirectly, the topography of the site may be altered as, it is presumed that on-site creation of wetlands is going to be a required component of the mitigation plan, which will require site work to modify the site elevation to create suitable wetland hydrology. 2. Soils- As with the topography, the soils have been modified in the bermed areas through compaction and introduction of non-native soils. The proposed project will result in further alteration of the soil types currently existing on-site. Modification will primarily be due to compaction and reduction or elimination of natural percolation of precipitation through the soil because of impermeable coverage. An indirect impact associated with the proposed plan results from change in elevation in the area proposed for creating wetlands. In this area, which is now Baymeade, fine sand, decrease in the elevation will result in more frequent innundation or saturation near the land surface, resulting in increased anaerobic conditions within the soil profile. Over time these soils will exhibit hydric characteristics and, eventually, be considered hydric. 3. Land use- On-site land use will be altered as a result of the proposed project. Some wetlands will be filled and converted to uplands and used for construction of public buildings. An indirect change in land use will result from constructing wetlands from current uplands. 4. Wetlands- 2.73 acres of wetlands upon the subject property will be filled as a result of the proposed project. This activity will require an Individual Permit from the United Page 6 of 10 States Army Corps of Engineers. A detailed discussion of the impacts to wetlands and proposed compensatory mitigation is presented in a Wetland Mitigation Plan which is included as Appendix 1. 5. Prime or Unique Agricultural Lands-The proposed project will not result in impact to or loss of agricultural land. 6. Public lands, and Scenic, Recreational and State Natural Areas-The proposed project will not result in impact to, or loss of Public lands or Scenic, Recreational or State Natural areas. 7. Areas of Archaeological or Historical value- Correspondence addressing the findings of the Historic Preservation Office of the Department of Cultural Resources will be included as Attachment I upon completion. It is the opinion of the Department that no historic or archaeological resources would be adversely impacted by the proposed activity. 8. Air Quality-The proposed project will not result in a construction of a facility which will be required to be permitted as a source of emissions. No regulatory compliance requirement will be associated with the proposed facility. Construction of the proposed facility will be achieved by use of vehicles and heavy equipment that will be powered by internal combustion engines. Thus, during construction an increase in oxides of nitrogen, sulfer and carbon, and VOCs typical of internal combustion engine powered vehicle operation will result. These same atmospheric contaminants will increase in the project area when the facility is in use. However, regionally, the increase in these compounds to the atmosphere will not increase as activities associated with the proposed public buildings already exist in the Town of Manteo. The nearest Class 1, protected area exists at the Swanquarter National Wilderness Area, approximately 55 miles from the subject site. Potential atmospheric contaminants from Roanoke Island are not expected to impact this protected area. 9. Noise Levels-During construction of the proposed facility noise levels on the property will increase. Following construction, use of the subject facility will increase noise levels on the property and, through concentrated vehicle use, in the vicinity of the property. The significance of the increase in operational and vehicle noise resulting from use of this facility is lessened however, considering the future noise associated with traffic flow on the new U.S. 64/264, adjacent to the site. 10. Water Resources- Runoff from the project site shall be contained within stormwater retention basins. By design, it is not likely that surface waters will be degraded by the proposed project. Additionally, the project design does not propose groundwater withdrawl. The project will result in an increase in impervious surface cover of 2.73 acres. 11. Forest Resources- Some forested wetlands and uplands will be impacted by the proposed project through road construction and fill for parking areas and buildings. Although the proposed project covers approximately 6.53 acres, approximately 5.3 acres of this is currently cleared and bermed for dredge spoil placement. The area of forest resource Page 7 of 10 impacted will be 1.24 acres. This area consists of forested and shrub/scrub wetlands and forested uplands. 12. Shellfish or Fish and their Habitats- No impacts to the fish or shellfish habitat are anticipated in relation to this project. As determined by the North Carolina Division of Marine Fisheries, no shellfish leases exist in Shallowbag Bay or in in the Croatan Sound within the project's vicinity. 13. Wildlife and Natural Vegetation- As discussed in Section E. 11 above, 1.23 acres of forest or scrub/shrub habitat will be lost as a result of the proposed activity. Section D. 13 identifies the threatened or endangered species found in Dare County. None of these species have been reported in the vicinity of the subject site. Habitat similar to that lost on the subject site by the recent dredge spoil placement and by the subject property is located north and west of the subject site. Wildlife that may be displaced by the proposed project may find suitable habitat there. 14. Introduction of Toxic Substances-The proposed project will result primarily in the construction of public office space. The nature of future use would not be expected to involve the use or storage of hazardous materials or substances. During the construction of the proposed facility it is likely that fuel for equipment will be brought to the site and possibly stored. Although storage of this type of substance presents a potential threat to the environment if a release occurred, typical management practices, materials handling and storage protocol, and proper containment should prevent this, or at least lower the risk. F. MITIGATIVE MEASURES The design of the proposed facility has undergone a series of design modifications throughout the last year and reflects continued attempts to minimize and avoid impacts to natural resources and jurisdictional wetlands. At present, the anticipated impacts to wetlands will be 2.73 acres. To offset the unavoidable impacts Dare County proposed to mitigation for these impact in the form of approximately 20:1 on-site preservation of existing wetlands, creation of a on-site, in-kind wetlands within upland areas of the subject property, and the purchase of mitigation credits at a ration of 2:1 in an approved mitigation bank or by direct payment to an appropriate conservation fund.

This project will provide necessary administrative facilities needed to keep pace with the growth of Dare County, and will be constructed on existing county-owned land next to the existing Dare County Justice Center. Funding for the project is being provided by the county and the state. Introduction The specific goal of the construction is to build a high quality administrative facility for the people of Dare County. The project will create a self-contained and cost-effective government facility in an environmentally sensitive and well-planned manner. The new building will be located next to the county's justice Center building. The Justice Center is owned by Dare County and was constructed in 2001-2002 to provide modern facilties and significantly more space for courthouse proceedings. The property is located within the zoning jurisdiction of the Town of Manteo. Mulkey, Inc. (Mulkey) has been retained to provide land development design and Section 404/401 permit application services. Both Dare County and the Town of Manteo have included development of a County government complex in their development and planning documents, as a way to address future growth and demand for services. Further information concerning this proposed project is provided in the Environmental Assessment (EA) document, dated November 1, 2000, which was previously submitted to the North Carolina State Clearinghouse and for regulatory agency review. A Finding of No Significant Impact (FONSI) was completed in early 2001. The EA considered both the existing Dare County Justice Center and future outbuildings that include this proposed project. A reevaluation of the existing jurisdictional wetland areas on the subject property was approved by the United States Army Corps of Engineers (USACE) on June 28, 2005. The North Carolina Division of Coastal Management (TNCDCl\1) has declined jurisdiction over the wetlands and surface waters within the proposed project area.

Purpose and Need The plan to expand of the county facilities was developed in response to the forecast need for consolidated county administrative operations, the desire to increase county efficiency, and to reduce overall cost to the county operations budget. Proposed site uses include expansion of the current administration facilities and the eventual construction of additional county buildings and associated parking. The purpose of the proposed project is to construct an administrative building associated with the existing Dare County Justice Center building. This project will be located on county property adjacent to the existing courthouse building. At present, some county employees are still utilizing older, disjunct county buildings located throughout the county, primarily in Manteo. This proposed construction would further alleviate problems with communication between different county agencies and employees to make for a more effective work environment. It would also continue to move all of the county service employees to one location, which is the future goal of the Dare County planning department. Water Resources Wetland delineations were originally completed for this project and subsequently approved by the USACE in March 1999. The delineation boundaries were recertified by the Corps during a field meeting held June 28, 2005. The project is located in Pasquotank River subbasin 03-01-51 and USGS 8-digit hydrologic unit 03020105. No streams are located within the project area; however, there is a large culvert beneath US Highway 64 which hydrologically connects the wetland areas on the project site to wetlands on the opposite side of the highway to the south. These wetlands eventually drain into tributaries and marsh land associated with Roanoke Sound. Surface water resources in the vicinity of the subject property include Shallowbag Bay (Class SC waters) to the north, the Roanoke River (Class SC waters) to the east, and Croatan Sound (Class SA waters) to the west. There are three areas of 303 (d) waters in the vicinity of the project study area, the Roanoke Sound from Shallowbag Bay to Johns Creek approximately 1.5 miles east of the project area, Sandbeach Creek approximately 1.5 miles southeast of the project area, and the Roanoke Sound at Mill Landing approximately 1.5 miles south of the project area. The existing jurisdictional wetlands on this property were significantly disturbed in the past by extensive clearing. These areas are best classified as bottomland hardwood wetlands as they were once part of the bottomland hardwood wetlands to the south prior to the construction of US 64. The National Wetlands Inventory (NWI) classification is palustrine saturated forest (PFO). June 9, 2006 US Army Corps of Engineers Nir. Tom Steffens Page 3 Permanent Impacts: Project construction will create a total of 0.95 acres of permanent fill in jurisdictional wetlands. These impacts are shown on the attached Wetland Permit Impact Summary Table and permit design drawings. Avoidance, Minimization, and Compensatory Mitigation Section 404 of the Clean Water Act requires regulation of discharges into Waters of the United States (U.S.). Surface waters, including lakes, rivers, and streams are subject to jurisdictional consideration under the Section 404 program. Wetlands are also identified as Waters of the U.S. Avoidance, minimization, and compensatory mitigation are considered in sequential order when addressing impacts to Waters of the U.S. Avoidance and minimization measures were incorporated during the project planning and National Environmental Policy Act (NEPA) compliance stages as noted in the following sections. Avoidance: The natural resources of the project site have been carefully used in planning for this primary and driving use for the success of the proposed project. The facilities have been designed to incorporate and enhance the natural resources of the site. The wetlands are so extensive throughout the subject property that impacts to these areas cannot be avoided except by choosing a no-build alternative. Undisturbed wetlands located near the intersection of I\iarshall Collins Drive and US 264 Business will remain undisturbed and will be avoided. Other adjacent tracts of county-owned land have been previously placed into permanent conservation easements and will be avoided. The project as planned avoids impacts on natural resources to the maximum extent practicable. Avoidance of impacts on wetlands was a central effort in the many considerations of infrastructure and facilities designs. The land plan, roads, utility corridors, and other developmental aspects of the proposed project were all planned after the wetlands were thoroughly investigated. Minimization: Wetland impacts from the proposed building construction have been minimized to the extent possible by aligning the building, parking lot, and associated stormwater ponds to take advantage of the greatest amount of upland on the property. In addition, a large retaining wall is planned for the southern edge of the building and parking lots site to minimize the amount of wetland fill in these areas. Without this retaining wall nearly all of these wetlands would need to be impacted by fill slopes in order to bring the proposed construction to the required flood zone elevation. Project-specific measures will be employed to minimize impacts to Waters of the U.S. during project construction. All practicable means will be employed to minimize wetland impacts due to runoff, sedimentation, or other construction activities. Best Aanagement Practices (BIVIPs) will be strictly enforced to control sedimentation during project construction. Clearing and grubbing activities will be minimized where possible and vegetation will be reestablished on exposed areas with judicious pesticide and herbicide management. Appropriate measures will be taken to avoid spillage of construction materials and provisions will be made for storing and handling waste materials in a manner that prevents materials from entering the streams or wetlands. June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 4 Compensatory Mitigation: Dare County has proposed to pay into the North Carolina Ecosystem Enhancement Program (NCEEP) for all wetland impacts proposed for this project. These impacts will be paid for at a 2:1 ratio. In a letter dated May 3, 2006 (attached) the NCEEP has agreed to provide in-lieu-fee mitigation for this project. Utilities Utility relocation is not anticipated with this project; however, water and sewer connections will be included. Any environmental impacts from future utility relocations will be the responsibility of the individual utility companies. The utility companies with services located in the project vicinity include Eastern North Carolina Natural Gas Company, Charter Communications, Dominion North Carolina Power, Sprint, Dare County Water Department, and the Town of Manteo Waste Water Treatment Plant. A water line connects to the courthouse building from US 64 Business along Marshall Collins Drive, and a sewer line force main that runs along US 64 bypass, connects to the courthouse on the western side of the building. FEMA Compliance The entire site is located within a designated Federal Emergency Management Agency (FEMA) flood zone, Zone A6 (Map # 3753480220C, February 19, 1986). Appropriate actions are being considered in the design of the proposed building to meet or exceed elevation standards for buildings within the flood zone. Indirect and Cumulative Impact Analysis Existing rules for the 401 Water Quality Certification Program (15A NCAC 2H.0506(b)(4)) requires the NCDWQ determine that a project "does not result in cumulative impacts, based on past or reasonably anticipated future impacts, that cause or will cause a violation of downstream water quality standards." A copy of the Indirect and Cumulative Impact Study is included in Appendix A. As noted in Section 3 of the EA document, existing land uses near the property are primarily undeveloped forest land to the north, west, and south. East of the subject property beyond Business Highway 64 is low-density residential and commercial development. The nearest residential properties to the proposed Administrative Services building are approximately 0.25 mile north of the building site. Proposed future construction activities include the construction of an additional county services building along US 264 Business near the current location of the Dare County Alcohol Beverage Control (ABC) store. In addition, wetland remediation activities are planned for the wetland areas immediately south of the proposed building (between US 64 and the proposed building site). These wetlands have been significantly disturbed in the past from clearing, grubbing, digging, and mulching activities. A future remediation project June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 5 would serve to make these wetlands functional again and provide for wetland education opportunities. Cultural Resources The EA document indicated the North Carolina State Historic Preservation Office (SHPO) found no documented historic properties within the project study area or in the immediate surrounding areas that would be impacted by the proposed project. There has been no change in structures since the 2000 EA. Essential Fish Habitat The 1996 amendments to the Magnuson-Stevens Fishery Conservation and Management Act (MSFCMA) set forth a new mandate for the National Marine Fisheries Service (NMFS), regional fishery management councils (Fl\4Cs) and other Federal agencies to identify and protect important marine and anadromous fish habitat. The Essential Fish Habitat (EFH) provisions of the MSFCI\iA support the Nation's overall marine resource management goals - maintaining sustainable fisheries. The FMCS, with assistance from the NMFS, have delineated "essential fish habitat" for managed species. Essential Fish Habitat is defined in the MSFCI\IA as "those water and substrate necessary to fish for spawning, breeding, feeding or growth to maturity." According to the proposed master plan associated with the government center expansion, no estuarine areas exhibiting seagrass, creeks, mud bottoms or estuarine water columns, or marine areas will be adversely impacted as a result of construction. Federally-Protected Species Federal law requires that any federal action likely to adversely affect a species listed as federally protected be subject to review by the U.S. Fish and Wildlife Service (USFWS) or National Marine Fisheries Service (NMFS) (under the provisions of Section 7 of the Endangered Species Act [ESA] of 1973, as amended). Prohibited actions which may affect any species protected under the ESA are outlined in Section 9 of the Act. Other species may receive additional protection under separate laws such as the Lacey Act Amendments of 1981, the Migratory Bird Treaty of 1999, the Marine Manurial Protection Act of 1972, or the Eagle Protection Act of 1940. North Carolina Natural Heritage Program (NCNHP) maps were reviewed in May 2005. The March 9, 2006 USFWS list of federally protected species for Dare County, North Carolina lists eight Endangered species and six Threatened species. The building site consists of cleared land with three small borrow ponds adjacent wetlands and a few young loblolly pine (Phats taeda) trees throughout. The subject property provides suitable habitat for the American alligator, glossy ibis, little blue heron, snowy egret, tricolored heron, star- nosed mole, and Carolina glasswort. This suitable habitat is generally located within the marsh and wetland areas. None of these species were observed during the field investigations. A review of NCNHP records in May 2005 revealed no federally or state listed species within one-mile of the project study area. Therefore, this project will have no June 9, 2006 US Army Corps of Engineers Mr. Tom Steffens Page 6 impact on protected species. Table 1 in the Appendix depicts the federal and state protected species listed for Dare County and their status. Adjoining Property Owners A review of the property parcels adjacent to the County's Justice Center Building determined that there are 11 adjacent properties to the project site. The surrounding area contains residential, commercial, and undeveloped properties. There are three residential properties located near the northern corner of the site. There are two undeveloped properties to the north and east of the subject property, and a vacant lot to the west between commercial and residential properties. There are four commercial properties to the west, two office buildings, a pharmacy, and an auto parts store. The North Carolina Department of Transportation (NCDOT) owns a substantial amount of right-of-way associated with US Highway 64 to the south of the subject property, and a smaller amount of right-of-way to the east associated with US Highway 264 Business. The state of North Carolina also owns the undeveloped forest land beyond US Highway 64 to the south. Table 2 lists the adjoining properties, the owner name, and owner addresses. The property numbers correspond to the property locations shown on Figure 3 (Appendix).

Approximate size of jurisdictional area: 1.54 acres. There are "isolated non-navigable, intra-state waters or wetlands" within the reviewed area. El, Decision supported by SWANCC/Migratory Bird Rule Information Sheet for Determination of No Jurisdiction. BASIS OF JURISDICTIONAL DETERMINATION: A. Waters defined under 33 CFR part 329 as "navigable waters of the United States": The presence•of waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. B. Waters defined under 33 CFR part 3283(a) as "waters of the United States": (1) The presence of waters, which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are su. ect to the ebb and flow of the tide.. (2) The presence of interstate waters including interstate wetlands . (3) The presence of other waters such as intrastate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate commerce including any such waters (check all that apply): ? (i) which are or could be used by interstate or foreign travelers for recreational or other purposes. ? (ii) from which fish or shellfish are or could be taken and sold in interstate or foreign commerce. ? (iii) which are or could be used for industrial purposes by industries in interstate commerce.

Shriver, PE County Enbineer LAND OF BEGINNINGS Qualitative Indirect and Cumulative Impacts Assessment of the Administrative Services Building Dare County Justice Center Dare County Dare County, North Carolina Prepared for NC Division of Water Quality Prepared by f =-MULKEY E"K GIt:EE RG t. CC?L ?'ITS?:TF May 2006 Qualitative Indirect and Cumulative Impacts Assessment of the Administrative Services Buildings Dare County Justice Center Project Introduction Dare County proposes to construct an additional administrative building with associated parking on an undeveloped portion of the existing Dare County Justice Center site. This expansion is part of the long-range county planning to bring county services to one location. This document is meant as an addendum to the original Environmental Assessment (EA) document, Section E "Predicted Environmental Effects of Projects." Study Area The purpose of this indirect and cumulative impact summary is to provide an assessment of the effects the proposed project will have on natural resources in the watershed surrounding the project area. The Council on Environmental Quality describes indirect impacts as those "that are caused by the action and are later in time or farther removed in distance, but are still reasonably foreseeable" (40 CFR 1508.8). Cumulative effects, are "impacts on the environment which results from the incremental impact of the action when added to other past, present, and reasonably foreseeable future actions regardless of what agency (federal or nonfederal) or person undertakes such other actions" (40 CFR 1508.7). The area studied for this assessment is generally Dare County's jurisdictional boundaries, specifically the central portion of Roanoke Island where the project site is located. This watershed area is included in U.S. Geological Survey (USGS) hydrologic unit 03020105. The surrounding area contains low-density residential and commercial properties, with undeveloped forestland and marshland throughout The property currently supports the existing Dare County Justice Center, which houses the county tax offices, Register of Deeds, Sheriffs office, holding cells, five courtrooms, and Clerk of Court offices with support facilities. The future plans for the property is to centralize all of the county services to a central location with acceptable transportation access. Documentation and Background Information The following documents are incorporated as supporting documentation and as references for this assessment They are: • Dare County Justice Facility, an Analysis of Alternatives (August 2000): The review process included assessments of available properties on Roanoke Island that are sufficient in area for the project, associated environmental impacts, cost of the available properties, traffic flow and potential congestion at the sites reviewed, accessibility to the courthouse by all citizens of Dare County, safety issues related to transportation of prisoners by law enforcement officers to the facility and associated security for attorneys, judges, and courthouse personnel. • Draft Roanoke Island Transportation Plan: The purpose of this plan was to develop a transportation plan that identifies potential transportation projects for short-term, mid- term, and long-term conditions. As a planning level document, this transportation plan for Roanoke Island establishes the general guidance and direction for the future transportation network on Roanoke Island. Natural Resources Natural resource investigations were conducted by Mulkey, Inc. (Mulkey) personnel in May 2005 for the proposed project. Quible & Associates conducted previous wetland delineations on the subject property and a formal jurisdictional determination re-verification was approved by the USACE for the site on June 28, 2005. Potential for Indirect and Cumulative Effects According to guidance developed for assessing indirect and cumulative impacts caused by implementation of building projects, several factors are taken into consideration when evaluating the potential for impacts. The following is an assessment of these factors as they relate to the proposed project. • Conflict with Local Plan As previously discussed, the proposed project is consistent with local and regional planning and is included in Dare County's planning documents. It is not in conflict with any local or regional land use plans or zoning. • Explicit Economic Development Purpose The purpose of this project is to provide additional office and conference space for various existing county services. • Stimulation of Complimentary Land Development Stimulation of complimentary land development is most likely to occur when projects are located near undeveloped sites. Complementary development can occur in either urban or suburban areas, and is more likely to be associated with a greater proportion and mix of higher density uses. Since this is merely an addition to the existing Dare County Justice Center complex little off-site development is anticipated to occur from the construction of this project The majority of the development that has occurred since the original Dare Justice Center was completed in 2002 has been the result of the recently constructed 4-lane US Highway 64 bypass of Manteo. 2 Notable Features in the Project Area jurisdictional wetlands are found throughout the proposed construction site. These resources are described in the attached cover letter report Efforts have been taken to avoid and minimize the impacts to wetlands as much as feasible. The layout of the building and associated parking were oriented so as to use the greatest amount of non-wetland acreage. Also, a retention wall will be constructed on the south side of the proposed building to significantly minimize wetland impacts. Analysis of Indirect and Cumulative Impacts This analysis is by necessity a brief overview of potential impacts to natural resources from indirect and cumulative effects. A summary of the indirect and cumulative effects analysis indicates the following. • Growth trends indicate that Dare County, the Town of Manteo, and surrounding areas are continuing to grow, driven primarily by a tourism industry found throughout coastal communities. All community services are then by necessity needed to grow to meet the demands of the population. This proposed Administrative Services building will serve to provide current and future needs for county services from its citizens. • The undeveloped land surrounding the Dare County site will likely remain undeveloped due to significant wetland and coastal acreages and because it is land-locked with no roadway access available. In addition, a substantial portion of the surrounding undeveloped land has been placed into a permanent conservation easement from the construction of the original Dare County Justice Center building. Local changes in zoning designations or land use are not anticipated as a result of this project The surrounding area is zoned for residential and commercial development, which will potentially create more impervious surface per acre than existing levels. This could lead to increases in surface water runoff from these surfaces; however, this project is not anticipated to spur this growth. • The project area contains both wetland and non-wetland areas that have been significantly disturbed in the past from clearing, grubbing, digging, and mulching activities. The wetlands are not fully functioning and are not high quality. Therefore, these communities are not unique and provide wildlife habitat primarily to those species that have adapted well to man-dominated or altered communities. • Due to the distance from the Roanoke or Croatan Sounds, water quality degradation is not anticipated from the construction of the proposed administrative building. Strict adherence to all federal, state, and local regulations during construction will help ensure that the surface waters are not negatively impacted or that impacts are minimal. • The potential does not exist for private residences to transition to businesses due to implementation of this project 3 • The consequences of potential ecological effects are expected to be minor since the project site is in a suburban area. With proper adherence to regulations, it is anticipated that this project will not produce substantial changes in the ecological makeup of the study area; therefore, the consequences of such effects are expected to be minimal. Mitigation of Indirect and Cumulative Impacts Several layers of federal, state, and local regulations and ordinances designed to protect the natural environment, and water quality in particular, already exist. All development projects, whether completed by Dare County or other entity, must follow these guidelines in order to mitigate potential indirect and cumulative impacts. The regulations and programs listed below are not intended to be definitive or restrictive. New rules and regulations may be promulgated in the future that will provide additional levels of environmental protection. Federal and State Regulations Clean Water Act: Section 404 and Section 401. These programs regulate impacts to jurisdictional surface waters, including streams, wetlands, and certain impounded waters. All private and public construction activities must obtain applicable permits and certifications prior to commencing work that will affect these regulated resources. Primary components of the 404 and 401 programs is the requirement for avoidance and minimization of impacts before the agencies consider permit applications. • Clean Water Act: Section 303(d). Waters identified by the State as not supporting the intended uses must be identified on a statewide list of impaired waters. Water pollution sources must be identified and the total maximum daily limits (TMDL) of pollutants allowed must be allocated among the permitted dischargers. • Clean Air Act: The subject property is located in an area classified as a "complete attainment" area by the North Carolina Department of Air Quality. The air quality is expected to remain within allowable pollutant levels. • Endangered Species Act of 1973: Protects and conserves natural habitats of species that have been listed by the US Fish and Wildlife Service (USFWS) as threatened or endangered. • National Flood Insurance Program (NFIP): Protects stream riparian areas and wetlands, as well as water quality, by restricting floodplain development. Dare County and the Town of Manteo flood protection program meets or exceeds requirements of the non- regulatory national program. • National Pollution Discharge Elimination System (NPDES): Stormwater discharges controlled by NPDES are regulated by NCDWQ's Phase I and Phase II permit program. Under the Phase II program, local governments are required to implement measures for reducing and managing stormwater. North Carolina Archaeological Resources Protection Act (NCARPA): Archaeological resources on private or public lands are protected under NCARPA, the Unmarked Human Burial and Human Skeletal Remains Protection Act, the North Carolina Archeological Record Program, the State Environmental Protection Act, and other federal laws. The USACE requires an archeological review for projects needing a Section 404 permit • North Carolina Sedimentation and Pollution Control Act: Land disturbing activities such as construction projects must install and maintain adequate sediment control measures that prevent sediment from entering streams. The NC Division of Land Resources regulates construction activities by requiring application for a sediment and erosion control permit. • North Carolina Clean Water Management Trust Fund: A non-regulatory program that was created to address water quality problems by eliminating pollution, protecting and conserving unpolluted surface waters, and establishing riparian buffers. Conclusion It is reasonable to conclude that construction of the proposed Administrative Services building will not increase ecological impacts beyond those expected from current and future development plans for the region. The federal, state, and local regulations and ordinances that currently exist adequately provide protections for the natural environment and provide controls to limit indirect and cumulative impacts. FINDING OF NO SIGNIFICANT IMPACT Environmental Assessment for the Dare County Justice Facility Dare County February 15, 2001 An environmental assessment (EA) has been prepared pursuant to the requirements of the North Carolina Environmental Policy Act for the proposed Dare County Justice Facility. A new courthouse will be constructed on Roanoke Island in Dare County. This courthouse will consist of a two story primary building with two smaller out buildings and approximately 5 acres of parking facilities. This facility will consolidate services related to judicial matters into a facility that will better serve the needs of the County citizens. This project will be located on Roanoke Island in eastern Dare County. The abundance of wetlands on the 80-acre site presented a challenge for this project, however, the issues have been resolved. Approximately 60 acres are designated as wetland areas requiring a federal permit. In addition a wetland mitigation plan was required. The water resources of the region include surface waters in streams and drainageways and groundwater. None of the water resources of the region are likely to be impacted as a result of this project. There are no shellfish leases within the vicinity of this site. Air quality and noise levels may be impacted during the construction phase of this project, but the impacts are not likely to be long- term. A detailed "alternatives analysis" was conducted to evaluate the best location for the new justice facility. The "alternatives analysis" looked at numerous sites as well as renovating the existing courthouse in Manteo. The final location presented in the Environmental Assessment was chosen as it met all requirements needed to consolidate judicial activities into a centralized location. Mitigative measures will be incorporated into the project to reduce or eliminate further environmental impacts. These include providing mitigation at the rate of 20:1 for impacts to existing wetlands. 2.73 acres of wetland are anticipated to be affected by this project; hence, Dare County has also agreed to purchase mitigation credits at a ratio of 2:1 in an approved mitigation bank or by direct payment to an appropriate conservation fund. In addition, stormwater management facilities will be in place to minimize impacts of runoff. Based on the findings of the EA and on the impact avoidance/mitigation measures contained therein, it is concluded that the proposed project will not result in significant impacts to the environment. This EA and Finding of No Significant Impact (FONSI) are prerequisites for the issuance of the permit actions by the Division of Water Quality. Pending approval by the State Clearinghouse, the environmental review for this project will be concluded. An environmental impact statement will not be prepared for this project. Division of Water Quality February 15, 2001 Email communications concerning the EA and FONSI Cindy, If I recall that FONSI is less than five years old. Provided the new building was considered in it and no changes are proposed to what the FONSI authorized, the project can proceed to permitting. Please attach a copy of the FONSI to the permit application.

ENVIRONMENTAL ASSESSAIENT DARE COUNTY JUSTICE FACILITY ROANOKE ISLAND, DARE COUNTY, NORTH CAROLINA A. PROPOSED PROJECT DESCRIPTION Dare County has proposed to construct a new justice facility on Roanoke Island. The site selected for the courthouse is an approximately 80.64 acre tract of land located 1/8th of a mile northwest of the US 64/264 junction with NC 345 (at approximately 35° 53'22"N, and 75° 39' 41"W) on Roanoke Island, Dare County, North Carolina. Attachment A depicts the project location on a Site Location/Topographic Map. Attachment_ B presents the proposed justice facility and associated buildings, drive, and parking area, and areas of impact to wetlands. Specifically, the proposed project includes a two-story 35,112 square foot primary building with two out-buildings. Parking for the facility surrounds the buildings and covers a total of 208,646 square feet. Stormwater retention basins will be constructed as part of the overall development. The total impermeable coverage associated with the project is 284,316 square feet. Some grading and infrastructure construction will occur in wetlands. An approved Section 404 wetlands delineation for the subject property is included as Attachment C. The project site was selected following an analysis of alternative properties performed by Quible & Associates and the Dare County Capital Improvements Committee. This analysis is entitled Dare County Justice Facility, an Analysis of Alternatives, and is provided as Attachment D. The review process included assessments of available properties on Roanoke Island that are sufficient in area for the project, associated environmental impacts, cost of the available properties, traffic flow and potential congestion at the sites-reviewed, accessibility to the courthouse by all citizens of Dare County, safety issues related to transportation of prisoners by law enforcement officers to the facility and associated security for attorneys, judges and courthouse personnel. Also considered were surrounding property uses which might tend to detract from the courthouse and other aesthetic and visual considerations that would impact a facility that will be a long standing symbol of Dare County government. Following review utilizing all the parameters described above the subject tract was selected as superior to the other available alternatives. Following the site selection process, Dare County authorized Heery Architects and Quible & Associates, P.C. (Quible) to develop a preliminary design for the Courthouse utilizing the subject tract. The enclosed plan view of the project has been prepared with coordination and input from the Dare County Commissioners, Dare County Manager, Dare County District Attorney, Dare. County Sheriff's Department and presiding Judges that will hold court in the new facility. The proposed project at build out includes a total of 284,316 square feet. (6.53 acres) of impervious surface with approximately 118,919 square feet (2:73 acres) of that total located within Section 404 wetlands. A numerical breakdown of the proposed development and impacts is found on the enclosed plan view plat. The configuration of the courthouse complex has been manipulated by Quible and Heery to maximize use of the available uplands on the parcel and development within wetlands represents unavoidable impacts given the minimum requirements for the master plan developed. The project will be served with central sewer from the Town of Manteo and potable water is provided from the central Dare County system. Page 1 of 10 B. PURPOSE AND NEED FOR PROPOSED PROJECT Currently, Dare County government buildings with services related to judicial matters are located in separate buildings at a number of locations on Roanoke Island. There have been three separate studies in 1994, 1995 and 2000 concerning alternatives for improvements in that system and to analyze requirements related to the size, location, traffic flow, parking requirements and infrastructure requirements for renovation of the existing courthouse or for construction of a new facility. The County also identified a need for governmental services such as the tax office, clerk of court, registrar of deeds, law enforcement, court rooms, and other administrative buildings to be located in proximity to each to better serve the citizens of the County. The studies further indicated that a facility of approximately 70,000 sq. ft. with 400 parking spaces will be required to provide the combined services described above, and in more detail in the Alternatives Analysis included as an attachment to this EA. C. ALTERNATIVES ANALYSIS A comprehensive Alternatives Analysis is included at Attachment D. A summary of the comprehensive analysis revealed the following as the most reasonable alternatives if the proposed project was not permitted. No Action If a new judicial facility is not constructed then the problems that have been identified since the 1980's will continue to exist. (Note: See enclosed Attachment D outlining status of courthouse and associated administrative buildings prepared in 1984 by NCSU School of Design; Also enclosed is a March 30, 1998 letter from the Dare County Grand Jury to-the Dare County Board of Commissioners outlining deficiencies in operation and physical conditions associated with the current courthouse based on their use of the facility. Based on the referenced studies, and the continued growth of the case load that is occurring in Dare County, it is the position of the Dare Commissioners that continued use of the current facility is short sited and unacceptable. Renovation of Existing Courthouse A review of requirements for the renovation and expansion of the existing courthouse has identified two major problems. First, the existing courthouse, which was completed in 1904 has been calculated to contain 5,274 square feet of usable space on two floors. The courthouse is located on a small tract of land in the center of downtown Manteo with paved streets on three sides. The surrounding area is completely developed and therefore the opportunity to expand the facility either vertically or horizontally sufficient to meet current needs is extremely problematic. Secondly, parking in downtown Manteo has been at a premium for a number of years. Recently, the construction of new retail facilities and the expansion of the Roanoke Island Festival Park have made the traffic and parking problems even worse. No solution to the parking problems that would be created by the expansion of the courthouse has been identified short of removing existing buildings for the purpose of constructing required parking. Therefore, the renovation of the existing facility is considered impractical because it would create problems with traffic and parking downtown. For this reason the county has rejected this approach. Page 2 of 10 D. EXISTING ENVIRONMENTAL CHARACTERISTICS OF PROJECT AREA 1. Topography- The natural topography of the subject site is relatively level with a gentle slope toward the west, in the direction of Croatan Sound. A man-made bermed area exists in the vicinity of the proposed justice facility, and also further west, in the location of a former borrow pit. The bermed areas are devoid of vegetation and used for dredge spoil containment. The top of the spoil containment berm represents the highest elevation of the subject site. 2. Soils- According to the Dare County soil survey, dated March 1992, the subject property contains Hobonny, Leon, Baymeade, Belhaven, and Johns soil series. Hobonny, Leon and Belhaven series are considered hydric and Baymeade and Johns are considered to be non- hydric. All of these series are sandy to loamy sand, except for the Hobonny series which is a fiberous to sapric muck. Areas that have been developed for dredge spoil placement may no longer exhibit the natural soil profile. Soil survey data is depicted on a soils map included as Attachment E. 3. Land Use- Currently, the subject site is used for on-site disposal of dredge spoil, or is undeveloped wooded, shrub/scrub wetlands or coastal marsh. Land to the east of the subject site is developed commercially along US 64/264, and near the intersection of US64/264 and the new US 64/264 right-of-way. To the south of the subject site is the new US 64/264 right-of-way leading to the new Croatan Sound bridge. West of the subject site is the Croatan Sound. Adjacent property to the north of the subject site is undeveloped and wooded. The nearest residential land use occurs on the adjacent property to the northeast of the subject site. 4. Wetlands- 60.57 acres of wetlands exist on the 80.64 acre parcel. The "Section 404" wetlands are depicted on a map included as Attachment C. This wetland/upland line was delineated during 1998 and 1999 and verified by the United States Army Corps of Engineers by signature on March 15, 1999. These 404 wetlands consist of scrub/shrub and forested type systems that primarily a function as wildlife habitat. Coastal wetlands exist throughout the west and northwest areas of the site. These Juncus roemerianus dominated marshlands are under the jurisdiction of the North Carolina Division of Coastal Management. Through use of remote censing techniques, a total of 23.05 acres of coastal wetlands have been calculated on the site and can be viewed on Attachment F. These wetlands serve as wildlife habitat and also abate erosion during storm events. A comprehensive discussion of the wetlands upon the subject property, the proposed alteration of some of the wetlands for construction of the proposed facility, and compensatory mitigation proposed is included as a separate Wetland Mitigation Plan in Appendix 1. A site plat of the 80.64 acre parcel including impacted wetlands and proposed wetland mitigation area is represented as Attachment G. 5. Prime or Unique Agricultural Lands- The subject property contains marshland, wooded uplands, scrub/shrub wetlands or forested wetlands. None of the subject property is used for agricultural purposes. Page 3 of 10 6. Public Lands and Scenic, Recreational, and State Natural Areas- This subject property is privately owned by the Marshall C. Collins Family Limited Partnership. None of the surrounding properties are considered public lands or Scenic, Recreational or State Natural Areas. 7. Areas of Archaeological or Historical Value- A review of the subject property is being conducted by the Department of Cultural Resources at the Historic Preservation Office in Raleigh, North Carolina. According to the Eastern Office of Archives and History, the proposed site is not included as a zone of significant archaeological or historical value. 8. Air Quality- The subject property is located in an area classified as a "complete attainment" area by the North Carolina Department of Air Quality. The air quality is expected to remain within allowable pollutant limits. 9. Noise-Levels- The subject property is currently used for placement of dredge spoil. Additionally, the new US 64/264 Croatan Sound Bridge right-of-way borders the property to the south. Current noise on the property is minimal, except that from the work on the DOT right-of-way and operations associated with the dredge process. 10. Water Resources- The subject site is located in the Pasquotank River Basin. Surface water resources in the vicinity of the subject site include Shallowbag Bay (SC waters) to the north and Croatan Sound (SA waters) the west. The two bodies of water are connected by an approximately 2.0 mile ditch. This ditch is influenced by wind tides and may flow in either direction. Groundwater use in the vicinity of the subject site includes supply wells within the Skyco Water Plant Wellhead Protection area. These wells are developed within Quaternary deposits to a depth of approximately 250 feet. This zone is characterized by sediments deposited since the end of the Pliocene and includes interbedded layers and lenses of sand silt clay and mollusk shell. Ten wells are located in this area. Well installation records confirm the location, stratigraphy, hydrology and depth of each well. Recharge to this aquifer system is through precipitation infiltration through the soil zone. 11. Forest Resources- The subject property contains marshland, wooded uplands, scrub/shrub wetlands or forested wetlands. A comprehensive discussion of the vegetative communities on the subject property is contained within the Wetland Mitigation Plan included as Appendix 1. 12. Shellfish, Fish and their Habitat- The ditch that passes through the subject property connects the Croatan Sound with Shallowbag Bay. Croatan Sound is classified as SA waters and Shallowbag Bay is classified as SC waters. The fisheries of Croatan Sound are utilized by local commercial and recreational users. Shellfish leases are not located in the Croatan Sound in the vicinity of the subject site according to the Resource Enhancement Section of the North Carolina Division of Marine Fisheries. The fishery quality of Shallowbag Bay is not as significant as the Croatan Sound, presumably due to the commercial nature of surrounding land use which may have had some impact on the health or productivity of the water, and is in fact closed to shellfish harvest due to Page 4 of 10 pollutants. The ditch that connects these two water bodies passes through the subject property. During the spring through fall this ditch contains juvenile fish species, especially in the west end, closer to Croatan Sound. 13. Wildlife and Natural Vegetation-Rare and protected species listed for Dare County can be found in Attachment H. According to the USFNVS, federally protected endangered species listed for Dare County as of the February 28, 2000 listing include the kemp's ridley sea turtle (Lepidochelys kempit), hawksbill sea turtle (Eretomochelys imbricata), peregrine falcon (Falco peregrimus), red-cockaded woodpecker (Picoides borealis), roseate tem (Sterna dougalit) and manatee (Trichechus manatus). The Kemp's ridley, hawksbill and leatherback turtles are typically found in the open marine environment or on the beach when laying eggs, but may also enter the bays and sounds. These species and their habitat are not expected to be found in the project area. The peregrine falcon is a medium-sized raptor which nests on cliffs, river cutbanks, and trees; and hunts over open fields, waterways, and wetland areas such as swamps and marshes. The red-cockaded woodpecker is a small 20 to 22 cm (8 to 9 inch) wood boring bird found in open stands of mature pines. The roseate tern is a small black-capped bird with a deeply forked tail and black bill. It is a coastal species, found along salt bays, estuaries and oceans. The manatee is a large aquatic mammal found in both salt and fresh water in depths of 1.5 to 6 meters (5 to 20 feet) including canals, rivers, estuarine habitats, and saltwater bays. None of these federally listed endangered species have been reported on or within the vicinity of the Dare County Justice Facility site. Federally listed threatened species for Dare County include the loggerhead sea turtle (Caretta caretta), green turtle (Chelonia mydas), piping plover (Charadrius melodus), bald eagle (Haliaeetus leucocephalus), and the seabeach amaranth (Amaranthus pumilus). The loggerhead and green turtle are typically found at sea, but may also enter bays and sounds and may be found on beaches. The piping plover is a small 15 to 19 cm (6 to 7.5 inch) wading bird typically found on sand beaches and tidal flats. The bald eagle is a large raptor which nests in trees associated with coasts, rivers, and lakes. The seabeach amaranth is a monoecious annual herb with fleshy, roundish leaves, large fruits, and numerous branched stems. This reddish tinted amaranth is found on the upper beach and lower foredune of coastal barrier islands. None of these federally listed threatened species have been reported on or within the vicinity of the Dare County Justice Facility site. The red wolf (Canis rufus) is listed as experimental by the USFWS. Experimental species are treated as threatened on public land, for consultation purposes, and are proposed for listing on private land. The red wolf is a medium sized canid which inhabits any area of sufficient size that provides food, water, and thick vegetation for cover, including coastal prairie and marsh habitat. This species has been reintroduced into the Alligator River National Wildlife Refuge. The American alligator (Aligator mississippiensis) is listed as threatened due to the similarity in appearance and habitat preferences to the American crocodile (Crocodylus acutus), which is listed as an endangered species nationally. The alligator is not considered to be threatened or endangered and is not protected under the Endangered Species Act. Preferred habitats include: rivers, streams, lakes, ponds, swamps, wetlands, Page 5 of 10 and other low water areas where fish, fowl and small animals provide an adequate food supply. Alligators are also known to inhabit ditches and drainage systems. Nesting sites include low, wet herbaceous areas where a mound is built and eggs laid. Incubation temperatures are provided by decomposing vegetation incorporated into the nesting mound. During field work in the project area, no alligators or crocodiles were found. No sightings near the project area have been reported to the NC Natural Heritage Program. A determination was therefore made that this project would have no effect on the American alligator or American crocodile. The black rail (Laterallus jamaicensis), rafinesque's big-eared bat (Corynorhimus rafenesquii), and dune blue curls (Trichostema sp.) are listed as Federal Species of Concern (FSC) which may occur in Dare County. The black rail is a small 13 to 15 cm (5 to 6 inch) bird found in tidal marshes, grassy marshes and stubble fields. Rffinesque's big-eared bat is a medium-sized, long eared bat. Its preferred habitat is old growth forests and it is typically found in the coastal plain of North Carolina along river systems and other bodies of water. Dune blue curls are found on sandy and vegetated dunes, as well as in openings in maritime forests or shrub areas. None of these species were observed during visits to the subject site. Of all species with special Federal status, the Black Rail has the greatest potential to be located in the vicinity of the subject property. This species would most likely be found within the coastal marsh, and not directly in the project area. E. PREDICTED ENVIRONMENTAL EFFECTS OF PROJECTS 1. Topography- The existing site conditions do not represent the natural topography of the region as large soil berms have been constructed on-site for dredge spoil placement. The topography of the subject site will be directly altered by the proposed project. Indirectly, the topography of the site may be altered as, it is presumed that on-site creation of wetlands is going to be a required component of the mitigation plan, which will require site work to modify the site elevation to create suitable wetland hydrology. 2. Soils- As with the topography, the soils have been modified in the bermed areas through compaction and introduction of non-native soils. The proposed project will result in further alteration of the soil types currently existing on-site. Modification will primarily be due to compaction and reduction or elimination of natural percolation of precipitation through the soil because of impermeable coverage. An indirect impact associated with the proposed plan results from change in elevation in the area proposed for creating wetlands. In this area, which is now Baymeade, fine sand, decrease in the elevation will result in more frequent innundation or saturation near the land surface, resulting in increased anaerobic conditions within the soil profile. Over time these soils will exhibit hydric characteristics and, eventually, be considered hydric. 3. Land use- On-site land use will be altered as a result of the proposed project. Some wetlands will be filled and converted to uplands and used for construction of public buildings. An indirect change in land use will result from constructing wetlands from current uplands. 4. Wetlands- 2.73 acres of wetlands upon the subject property will be filled as a result of the proposed project. This activity will require an Individual Permit from the United Page 6 of 10 States Army Corps of Engineers. A detailed discussion of the impacts to wetlands and proposed compensatory mitigation is presented in a Wetland Mitigation Plan which is included as Appendix 1. 5. Prime or Unique Agricultural Lands-The proposed project will not result in impact to or loss of agricultural land. 6. Public lands, and Scenic, Recreational and State Natural Areas-The proposed project will not result in impact to, or loss of Public lands or Scenic, Recreational or State Natural areas. 7. Areas of Archaeological or Historical value- Correspondence addressing the findings of the Historic Preservation Office of the Department of Cultural Resources will be included as Attachment I upon completion. It is the opinion of the Department that no historic or archaeological resources would be adversely impacted by the proposed activity. 8. Air Quality-The proposed project will not result in a construction of a facility which will be required to be permitted as a source of emissions. No regulatory compliance requirement will be associated with the proposed facility. Construction of the proposed facility will be achieved by use of vehicles and heavy equipment that will be powered by internal combustion engines. Thus, during construction an increase in oxides of nitrogen, suffer and carbon, and VOCs typical of internal combustion engine powered vehicle operation will result. These same atmospheric contaminants will increase in the project area when the facility is in use. However, regionally, the increase in these compounds to the atmosphere will not increase as activities associated with the proposed public buildings already exist in the Town of Manteo. The nearest Class 1, protected area exists at the Swanquarter National Wilderness Area, approximately 55 miles from the subject site. Potential atmospheric contaminants from Roanoke Island are not expected to impact this protected area. 9. Noise Levels-During construction of the proposed facility noise levels on the property will increase. Following construction, use of the subject facility will increase noise levels on the property and, through concentrated vehicle use, in the vicinity of the property. The significance of the increase in operational and vehicle noise resulting from use of this facility is lessened however, considering the future noise associated with traffic flow on the new U.S. 64/264, adjacent to the site. 10. Water Resources- Runoff from the project site shall be contained within stormwater retention basins. By design, it is not likely that surface waters will be degraded by the proposed project. Additionally, the project design does not propose groundwater withdrawl. The project will result in an increase in impervious surface cover of 2.73 acres. 11. Forest Resources- Some forested wetlands and uplands will be impacted by the proposed project through road construction and fill for parking areas and buildings. Although the proposed project covers approximately 6.53 acres, approximately 5.3 acres of this is currently cleared and bermed for dredge spoil placement. The area of forest resource Page 7 of 10 impacted will be 1.24 acres. This area consists of forested and shrub/scrub wetlands and forested uplands. 12. Shellfish or Fish and their Habitats- No impacts to the fish or shellfish habitat are anticipated in relation to this project. As determined by the North Carolina Division of Marine Fisheries, no shellfish leases exist in Shallowbag Bay or in in the Croatan Sound within the project's vicinity. 13. Wildlife and Natural Vegetation- As discussed in Section E. 11 above, 1.23 acres of forest or scrub/shrub habitat will be lost as a result of the proposed activity. Section D. 13 identifies the threatened or endangered species found in Dare County. None of these species have been reported in the vicinity of the subject site. Habitat similar to that lost on the subject site by the recent dredge spoil placement and by the subject property is located north and west of the subject site. Wildlife that may be displaced by the proposed project may find suitable habitat there. 14. Introduction of Toxic Substances-The proposed project will result primarily in the construction of public office space. The nature of future use would not be expected to involve the use or storage of hazardous materials or substances. During the construction of the proposed facility it is likely that fuel for equipment will be brought to the site and possibly stored. Although storage of this type of substance presents a potential threat to the environment if a release occurred, typical management practices, materials handling and storage protocol, and proper containment should prevent this, or at least lower the risk. F. MITIGATIVE MEASURES The design of the proposed facility has undergone a series of design modifications throughout the last year and reflects continued attempts to minimize and avoid impacts to natural resources and jurisdictional wetlands. At present, the anticipated impacts to wetlands will be 2.73 acres. To offset the unavoidable impacts Dare County proposed to mitigation for these impact in the form of approximately 20:1 on-site preservation of existing wetlands, creation of a on-site, in-kind wetlands within upland areas of the subject property, and the purchase of mitigation credits at a ration of 2:1 in an approved mitigation bank or by direct payment to an appropriate conservation fund.

NO 27636 PH: 919-051-1912 FAX: 919-©51.191 3 www.MULKEYINC.COM 0 0 Dare County Administration Building Introduction This report presents the findings of a pre-development and post-development stormwater evaluation for a proposed Administration Building to be located on site with the existing justice Center in Manteo, North Carolina. The evaluation consists of a study of pre-development stormwater flows at the point of interest with the stormwater flows that will occur at the same point of interest after development of the building and parking lot. This study is intended to assure that the post development stormwater flow leaving the site will be equal to the existing stormwater flows and that the necessary stormwater devises to control, treat, and release storm events will be designed and implemented. This evaluation follows the guidelines set forth by the Town of Manero, Dare Coutny and in conjunction with the State of North Carolina Division of Land and Water Quality (NCDENR). Methodologies The methodologies to be used for determining the anticipated peak flows of runoff follow the State Stormwater Design Criteria, for computing peak flows. The flows will be used to analyze the existing stormwater conveyance structures and their capacity to handle additional flows. We have used NRCS type I storms to model the storms, which is common practice in Coastal, North Carolina area. Post development areas have changed in drainage pattern but have been accounted for in the proposed storm system. The time of concentration is the time it will take for the first amount of runoff in the most remote point in the watershed to reach the point of interest by overland flow, shallow concentrated flow and channelized flow. Once a time equal to the time of concentration has passed, the entire watershed is contributing to the runoff at the point of interest and therefore the watershed has reached its theoretical peak flow. n Data Gathering A topographic survey was completed for the proposed site. Currently, the site consists of a lightly wooded areas, wetlands, marsh, gravel compacted, and the existing justice Center along with parking. The proposed recombined site consist of approximately 21 total acres with only approximately 2.6 acres of that being the actual new development, approximately 0.7 acres being parking lot redevelopment, and approximately 1.7 acres of wetland enhancement area. Calculation Results Post-development flows have been evaluated based on minor grading revisions, the construction of Administration Building, parking, and other necessary impervious areas for the site. These areas include the addition of retaining walls, sidewalks, soild waste disposal area, mechanical yard and load/unload areas. i i'r a Stormwater Treatment and Quantitative Control Construction of the proposed building will require treatment of the first inch and a half of rainfall. Treatment of the first inch and a half of stormwater can be achieved through the planting soil and sand filter layers of the bioretention pond along with the grass swales in the medians and finally in the constructed wet pond. Treating the first inch and a half of stormwater runoff would result in the treatment of approximately 79,480 gallons. This would be equivalent to approximately 10,625 cubic feet of needed storage in the series of treatment areas. The wet pond has been upsized to account for the future impervious area and to allow for more treatment in proposed conditions. The outlet structures has been sized to account for the one, two, and ten storm events by releasing those flows under or at pre-development conditions. \Vith respect to a larger storm, the 25 year storm, would fill the detention area and then be sheet flowed over a well maintained grass berm into the wetland enhancement areas that are proposed. Quantitative control through the use of the yard inlets in the grass swales to the bioretention pond and then on to the wet pond will handle and control one, two, and ten year storms. Please refer to the Storm Plan (C-7) and calculations for more details on the storm system. ri LI 0 I _MULKE CN GINEERS C. CONSULTANTS Brief description of project: The project consists of the design of stormwater treatment and control devices for the expansion of the Dare County Administration Offices located in Manteo. In addition, wetlands located throughout the site that have developed in existing borrow pits will be modified to a more natural setting to allow the free movement of wildlife. The project will also create an educational area so that children can learn about the purpose and importance of wetlands. List project objectives & intended outcomes (include the water quality issues being addressed and the water bodies being impacted): • Treat stormwater runoff from the proposed impervious areas (building and parking lots) to remove pollutants prior to release into the surrounding water bodies. Oil and grease, total suspended solids (TSS), heavy metals and nutrients are some of the targeted pollutants which will be treated on-site. • Control stormwater to pre-development conditions based on a 10-year storm event. • Create a more natural feel to the "unnatural" wetlands located throughout the site. Isolated wetlands have developed in rectangular areas that previously were utilized as borrow pits. The proposed project would connect these areas to allow free movement of wildlife between the wetlands. The rectangular outlines would be modified to create a more natural feeling to the wetlands. • Create an educational area which illustrates and explains the purpose and importance of wetlands in the environment. Expected product(s) of the project and how the projects success will be measured: The project will allow the construction of the proposed buildings and parking areas to serve the citizens of Dare County while minimizing impacts to the surrounding environment and improving the performance of the wetlands located throughout the site. Stormwater from the site can be monitored to ensure treatment levels for the specified pollutants are achieved. Active wildlife throughout the site will also verify a successful project. Active use of the site by the surrounding schools to educate children on the importance of wetlands will be apparent. In addition, this project would provide an example of the ability for the growth of a community to occur while still being respectful to the environment and will provide a blueprint for success for future generations.

Based on loblolly pine as the indicator species, the ordination symbol is 9W. JoA-Johns loamy sand, 0 to 2 percent slopes. This nearly level, moderately well drained and somewhat poorly drained soil is on low, smooth ridges on Roanoke Island and in Manns Harbor. The smaller mapped areas are commonly oval, and the larger areas are irregular in shape. The size of the areas ranges from 3 to about 100 acres. Typically, the surface is covered with 3 inches of partially decomposed needles, leaves, and twigs. The surface layer is very dark gray loamy sand about 4 inches thick. The subsurface layer is gray loamy sand about 4 inches thick. The upper part of the subsoil is very dark brown loamy sand about 5 inches thick. The rest is about 13 inches thick. It is yellowish brown sandy loam in the upper part and yellowish brown sandy clay loam in the lower part. The underlying material to a depth of 72 inches is sand. It is light yellowish brown in the upper part, very pale brown in the next part, and light brownish gray in the lower part. Permeability is moderate to rapid. The soil is very strongly acid or strongly acid. The seasonal high water table is 1.5 to 3.0 feet below the surface. Included with this soil in mapping are small areas of Baymeade and Icaria soils. Baymeade soils are on the slightly higher knolls. Icaria soils are in slight depressions. The included soils make up about 10 percent of the map unit. The Johns soil is used mainly as woodland. The dominant vegetation is loblolly pine, sweetgum, persimmon, live oak, and water oak. Wetness is the main limitation affecting woodland. The Johns soil in Dare County generally is not used for agriculture because of the lack of active farming on Roanoke Island and in Manns Harbor. Wetness is the main limitation affecting farming. The main limitation affecting urban and recreational uses is wetness. Also, the soil is too sandy for some urban uses. The wetness can be reduced by installing perforated drain tile, drainage ditches, or a combination of the two systems. The capability subclass is llw. Based on loblolly pine as the indicator species, the woodland ordination symbol is 9W. LeA-Leon fine sand, 0 to 2 percent slopes, rarely flooded. This nearly level, poorly drained soil is on Roanoke Island and in Manns Harbor. It is on flats and in slight depressions. Mapped areas are irregular in shape and range from 5 to 50 acres in size. Typically, the surface layer is dark gray fine sand about 7 inches thick. The subsurface layer is light gray Soil Survey sand about 8 inches thick. The subsoil is sand about 8 inches thick. It is dark brown in the upper part and dark reddish brown in the lower part. The underlying material to a depth of 72 inches is gray sand. Permeability is moderate to rapid. This soil ranges from extremely acid to strongly acid throughout. The seasonal high water table is at or near the surface. The soil is subject to rare flooding. Included with this soil in mapping are small areas of Icaria soils and areas of soils that have a dark surface layer more than 10 inches thick. The included soils are in landscape positions similar to those of the Leon soil. They make up about 10 percent of the map unit. The Leon soil in Dare County generally is not used for agricultural purposes. Wetness, flooding, and a scarcity of adequate drainage outlets are the primary limitations affecting agricultural uses. This soil is used as woodland. Loblolly pine, live oak, and water oak are the dominant species. The most common understory plants are waxmyrtle, fetterbush lyonia, gallberry, and American holly. Wetness in winter is a limitation; however, this soil is droughty during the growing season. The main limitations affecting urban and recreational uses are wetness, flooding, seepage, and the sandy texture. The capability subclass is IVw. Based on loblolly pine as the indicator species, the woodland ordination symbol is 7W. NeC-Newhan fine sand, 0 to 10 percent slopes. This excessively drained soil is on dunes on the Outer Banks. It commonly is adjacent to the Beaches-Newhan complex. It is within the salt-spray zone and supports salt-tolerant vegetation. Mapped areas are elongated and range from 2 to 1,300 acres in size. Typically, the surface layer is light brownish gray fine sand about 2 inches thick. The underlying material to a depth of 80 inches is fine sand. It is light yellowish brown in the upper part and very pale brown in the lower part. Permeability is very rapid. The soil ranges from moderately acid to mildly alkaline. The seasonal high water table is more than 6 feet below the surface. Included with this soil in mapping are small areas of Duckston and Corolla soils. These soils are in the lower, wetter troughs or depressions. They are common throughout the map unit. They make up 10 to 15 percent of the map unit. Most areas of the Newhan soil are covered with salt- tolerant grasses and shrubs. Some areas are used as sites for beach cottages, for recreational development, or as wildlife habitat.

An extended detention wetland must be also be designed with a forebay, as is a wet detention pond. The major difference between an extended detention wetland and a wet detention basin is that the allocation of surface area to different pond depths. For the system to function as a wetland, 70% of the area of the permanent pool needs to be designed as a marsh with a depth of 0 to 18", with an almost equal distribution of area (35% and 3591o) between 0" to 9" and 9" to 18." The other major difference is that there needs to be a small pool (15% of the surface area) where the outlet is located to prevent sediment from interfering with the outlet structure functions. The balance of the area is flexible with respect to depth. A most important consideration when designing both extended detention wetland systems and pocket wetland systems is the specification and installation of plants. Tables 4.1, 4.2, and 4.3 in chapter 4 will give a good indication of those plants that can be used in areas that will not be continually inundated. The ponding times, shown in days under Ponding, will give a good indication of what zones of the wetland the species should be planted. Shown below in Table 2.2 are those plants that should do well when planted within the normal, permanent pool of the wetland.

Wild Rice Table from: Design of Stormwater Wetlands Sys tems: guidelines for creating diverse and effective stormwater wetlands in the mid-Atlantic Re ion Schueler 2.7 Design Requirements for Pocket Wetlands In those situations where a combination of stormwater BMPs will be utilized to achieve the required 85% TSS removal, pocket wetlands in combination with grassed swales or filter strips can provide the needed removal. For design purposes these can be thought of as a special case of the extended detention wetland, or possibly a small wet detention pond with special emphasis placed on the wetland plantings. The sizing process should follow that of the wet detention basin, but with the following table (Table 2.3) used in place of Table 1.1. For example, a development of 4.5 acres, with 3.825 acres of imperviousness (85% imperviousness) would need a pocket wetland that.had 0.96% of 4.5 acres of permanent pool. One notable difference between this table and Table 1.1 is that no depths are given. An average depth of two feet is assumed. 19 MULKEY, INC. 59529 Invoice Number Date Voucher Amount Discounts Previous Pay Net Amount Permitting fee 5/24/06 0040609 200.00 0.00 0.00 200.00 NC Division of Water Quality Totals 200.00 0.00 0.00 200.00 2 36 797 JUN - 9 2006 OENR - IryATER QUAL17-y VFUtiOS A140 STOW MTER BUNCH WV 6E ~E5 ~8 900Z/9/6 u6[ S :q soe/e/5 UW E-3 'DUJJDUDj}DUJB}U~ ~JBBH '0} UOJ}DSUBdw00 pUD '}D }UBWa0J6D U6}}JJM SSBJd%a ey} y}(m }d00%0 aSOdJnd JBy}0 f~UD JO} pBSn aq }OU ~.DW }J '0}aJay} SUOJSUB}%B JO UJBJBy 0} paJJO}BJ JO pBj}J}UapJ }OB[OJd Of}JOBdS 0y} JO} SBOJAJBS 6UJp IAOJd SJ 'OU~JDUOJ}DUJa}U~ RJBaH eJJyM S}y6~J S,'OUJJDUOf}DUJa}U~ T~JBaH y}fM }UB}SJS000 JBUUDW D UI pBSn 0Cj I~~UO (~DW }J •s}y6JJ~doD 6ujpnpuJ 'uJeJey} s}y6JJ pc sulo}eJ •DU~ ~ouoJ}ouJa}u~ ~JaBH puo •DUJ •~ouoJ}DUJe}uJ ~JBeH }o ~}JetloJd ey} sj }uawnoop sJyl •penaesea s~y61u Ilo rout gouo~}ouae~u~ ~aeeH ~Q XXXX ~~U6~uRdo~ aaquanu ways r ~ ~ 4; :r i r " ~ i~L' - ' _ Jai" i ~i~ - r ~ - Ic ` Y tG ;A~;;,. - , / 4 ~ i i ~ l ~ • .
