This modification request is to the permit associated with the construction of the Briar Chapel Development in Chatham County, North Carolina. Specific plans and location information are described below and shown on the attached plans. This Public Notice and all attached plans are also available on the Wilmington District Web Site at www.saw.usace.army.mil/wetlands~~ Applicant: Newland Communities ~~~ Attn: Mr. Mitch Barron t~UC; ai ZU07 31 Hillsboro Street n~~a _ ~,f,, .,•, _, , ,,, L ~~ Pittsboro, NC 27312 w~nnNaSrd~;o 3ro~aah;ti~A,,~p aR,~cw Agent: Soil & Environmental Consultants, Inc. Attn: Ms. Nicole Thomson 11010 Raven Ridge Road Raleigh, North Carolina 27614 Authority The Corps will evaluate this application and a decide whether to issue, conditionally issue, or deny the proposed work pursuant to the applicable procedures of Section 404 of the Clean Water Act. Location The project, Briar Chapel Development, is approximately 1,589 acres in size and is located west of US Highwayl5-501, and north of Andrew's Store Road (SR 1528), and south of Mann's Chapel Road (SR 1532), approximately 5 miles south of Chapel Hill, in Chatham County, North Carolina. Coordinates (in decimal degrees) for the site are 35.8251 ° North, 79.1059 ° West. The site contains several unnamed tributaries of Pokeberry Creek and Wilkinson Creek, and adjacent wetlands, in the Cape Fear River y' Basin (8-Digit Cataloging Unit 03030002). The modification is to 5 previously permitted road crossings, one previously permitted utility crossing, and two pedestrian bridges within the subdivision. Existing Site Conditions The land use in the area surrounding the project consists primarily of large lot residential subdivisions, forested tracts, and agricultural tracts. The area is currently subject to increasing commercial and residential development pressure, in part due to the on-going widening of US Highway 15-501, which borders the site to the east. The land use on the project site itself is currently undergoing construction for the Briar Chapel Development. The site contains several tributaries to Pokeberry Creek, which runs from north to south through the heart of the property, and drains the majority of the land within the subdivision. The western-most portions of the site drain to Wilkinson Creek. A total of 61.4 acres of adjacent wetlands have also been identified on the site. Both Pokeberry and Wilkinson Creek flow into the Haw River several miles downstream of the site, which then flows into B. Everett Jordan Lake before merging with the Deep River to become the Cape Fear River. Applicant's Stated Purpose As stated by the applicant, the purpose of the project is to address the growing need for housing and commercial space in the area. Project Description The original project, known as the Briar Chapel Development, is a 1589 acre mixed-use development that includes construction of single-family residential areas, commercial and office space, community services such as parks, a County school, charter school, library, fire station, an EMS station, and over 900 acres of open space. The permit for the Briar Chapel Development was issued in September 2006, which authorized permanent impacts to 1,653 linear feet of stream channel and 0.6655 acre of wetland, and temporary impacts to 211 linear feet of stream channel and 0.137 acre of wetland. One of the original road crossings has been eliminated by the developer. This will reduce the intermittent stream impacts from the original permit by 1501inear feet and 0.2320 acre of wetlands. However, since the issuance of the permit, the North Carolina Department of Transportation has required design changes at 5 of the previously permitted road crossings which would require additional impacts to streams and wetlands. In addition, the location of one utility crossing has shifted slightly to address constructability issues and would require additional wetland impacts. Total permanent impacts associated with this permit modification would be 256 linear feet of stream channels exhibiting important aquatic functions and 0. ] 524 acre of wetlands, and temporary impacts to 0.1379 acre of jurisdictional wetlands. 2 The applicant has stated that mitigation under the original Briar Chapel permit was sufficient to cover the impacts proposed under this modification. This mitigation included a payment to the North Carolina Ecosystem Enhancement Program, the restoration of 2,127 linear feet of stream channel at the Harpers Crossroads Stream Mitigation Site, and the preservation of 63,412 linear feet of on-site stream channel and 59.3 acres of on-site wetlands. A compensatory mitigation determination will be made by the Corps prior to permit modification. 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 combined with appropriate application fee at the North Carolina Division of Water Quality central office in Raleigh will constitute initial receipt of an application fora 401. Water Quality 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 40 ] 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 August 24, 2007. 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 adversely impact EFH or associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management Councils or the National Marine Fisheries Service. Cultural Resources The Corps coordinated with the North Carolina State Historic Preservation Officer (SHPO) during the issuance of the original permit for this site. The permit was conditioned for the protection of sensitive areas as identified by the SHPO. The permit modification area is within the project area of the original permit. Therefore, the Corps is not aware that any registered properties, or properties listed as being eligible for inclusion therein that will 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 has determined pursuant to the Endangered Species Act of 1973, that the proposed project will have no effect on federally listed endangered or threatened species or their formally designated critical habitat. 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. For activities involving the discharge of dredged or fill materials in waters of the United States, the evaluation of the impact of the activity on the public interest will include application of the Environmental Protection Agency's 404(b)(1) guidelines. Commenting Information The Corps of Engineers is soliciting comments from the public; Federal, State and local agencies and officials, including any consolidate State Viewpoint or written position of the Governor; Indian Tribes and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects and the other public interest factors listed above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act (NEPA). Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Any person may request, in writing, within the comment period specified in this notice, that a public hearing be held to consider the application. Requests for public hearings shall state, with particularity, the reasons for holding a public hearing. Requests for a public hearing shall be granted, unless the District Engineer determines that the issues raised are insubstantial or there is otherwise no valid interest to be served by a hearing. 4 Written comments pertinent to the proposed work, as outlined above, will be received by the Corps of Engineers, Wilmington District, until Spm, August 24, 2007. Comments should be submitted to Monte Matthews, Raleigh Regulatory Field Office, 6508 Falls of Neuse Road, Suite 120, Raleigh, North Carolina 27615. 5 r ~ I ~+ O O '. O 'i O O N o o .
