Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: _Modification Text: The proposed modification to Impact Site #1 involves shifting the proposed crossing location downstream approximately 75 feet. This location is essentially the same as the previous crossing #1 location in all other respects. Original PCN Text: The project site consists of old pasture land and adjacent wooded land The old pasture area is close to an existing farm house with out buildings and landscaped areas The proposed utility lines and access road will pass just to the west of the farm house through an easement area cross a driveway and a small perennial stream (UT- Laurel Fork -P) within the acquired easement (Impact Site 1) After the first stream crossing the project passes out of the easement and onto Tract 2 of the Cottages of Boone project site. The utility line and access road extends into a wooded area following an existing woods road; a second crossing of an intermittent stream (UT- Laurel Fork -Int) will occur along this woods road (Impact Site 2). The site is accessed from Poplar Grove Road near NC Hwy. 105 a major transportation and commercial corridor. Poplar Grove Road leading away (south) from Hwy 105 winds through mostly rural agricultural, open, or low- density single family residential land use Impact Site 1: This site involves a small first order perennial stream (UT- Laurel Fork -P) flowing adjacent to an existing gravel driveway. The banks and riparian zone of this stream have been consistently maintained by the property owners by mowing and weed - eating For several hundred feet above Impact Site 1 the quality and character of the small stream has been influenced by landscaping and other similar activities. The quality of this stream is good despite a history of minor impacts Approximately 200 -feet below Impact Site 1 UT- Laurel Fork -P flows into the main stem of Laurel Fork. Impact Site 2: This site involves a small intermittent stream flowing through a wooded area The site consists of an existing woods road that was constructed at least 25 years ago The graded width of the existing road varies from 10 -feet wide to 25 -feet wide The woods road crosses UT- Laurel Fork -Int at Impact Site 2. An 8 -inch clay pipe, approximately 24 -feet long was installed years ago but has become domed at times and a gully has formed across the woods road from periodic high flow events The clay pipe currently conveys base flow. Immediately below the woods road there is an eroded area approximately 6 -feet deep with unstable vertical banks Two sections of the 8 -inch clay_ pine were undermined and lay in the bottom of the gully; only 16 -feet of clay pipe is currently functioning_ Approximately 80 -feet below the woods road UT- Laurel Fork -Int flows into a wetland and into Laurel Fork. 3b. List the total estimated acreage of all existing wetlands on the property: 0.012 acres 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: The project site contains approximately 200 linear feet of perennial stream and 40 linear feet of intermittent stream Page 4 of 14 PCN Form — Version 1.3 December 10, 2008 Version 3d. Explain the purpose of the proposed project: Modification Text: The purpose of the proposed modification to the location of crossing #1 is to eliminate the need to construct a new road bed just above and to the west of the existing gravel driveway. This modification will eliminate an area of rg ading approximately 200 feet long with 10 to 20 foot -tall cut slopes. In place of the new road the existing gravel driveway is proposed to be used The alternative alignment will involve minimal rg ading but much of it will occur within the trout buffer. A second purpose for this modification is the adjacent landowners (the Vannoys - house shown on Site Plan) not want a second road built adjacent to their driveway, they feel it would be an unnecessary disturbance and would negatively impact their view from their front porch. Original PCN Text: The project purpose is to install utility lines from proposed student housing units to the proposed waste water treatment plant (WWTP) and from the WWTP to various drip irrigation fields where the treated effluent will be discharged. The project also involves construction of an access road necessary for the installation and maintenance of the utility, lines. 3e. Describe the overall project in detail, including the type of equipment to be used: Modification Text: The proposed modification will shift crossing #1 downstream by approximate 75 feet. Approximately 200 feet of proposed new road will be eliminated Necessary improvements along the existing driveway will include widening by 2 or 3 feet in places installation of extra stone and erosion control measures. There will be a brief period of intense use of this road lasting perhaps 6- weeks. After this period usage will drop back to moderate levels for another 2 to 3 months After this time usage will be minimal. The second crossing (previously permitted) remains the same Original PCN Text: The overall project is to develop a multi - family residential facility designated for student housing The project will occur on two tracts of land purchased b the he Applicant and easements obtained by the Applicant from adjacent land owners to allow for access between the two tracts The project site is not served by municipal water or sewer; the Applicant has planned and received most of the approvals for an on -site water and sewer system. This application is for a NWP -12 and WQC -3884 to authorize impacts to jurisdictional waters at two locations associated with the installation of utility lines and the construction of an access road. (See Avoidance and Minimization Section for extensive description of the project) Typical equipment will be used as part of site development: trackhoe backhoe bulldozer, and dum truck.

If yes, explain in detail according to "help file" instructions. Modification Text: This application is to modify permits NWP - #3 and #12 issued 7 -2 -2012 under Action ID 2012 -00428 and WQC 3890 issued 7 -20 -2012 under DWQ# 12 -0561 A PCN for a NWP -3 (WQC 3883) was submitted to USACE on May 14, 2012. Written authorization from NCDWQ was not required for proposed activity but a courtesy copy of PCN was sent to DWQ. The proposed work involved maintenance upgrade of two existing pipes within DOT jurisdiction. Both pipes were outside of the Cottages of Boone project boundary but stormwater runoff was anticipated to impact both pipes and DOT made the pipe upgrades a condition of the driveway permit. No permanent impacts were proposed, temporary impacts were 0.0023 acres of wetlands and 20 linear feet of streams. Total impacts to streams and wet;ands associated with both PCN's will be 39 linear feet of permanent stream impact, 45 linear feet of temporary stream impact, and 0.0023 acres of wetland impact. 6.

The modification will result in approximately 13 additional linear feet of permanent impact and 2 additional linear feet of tem ora impact. The proposed pipe length remains the same as previously permitted but due to a Page 7 of 14 PCN Form — Version 1.3 December 10, 2008 Version tight radius and an expanded headwall /retaining wall there will be additional encroachment into the upper banks of the channel mostly on the upstream side of the crossing. In addition, a waiver to Condition #16 of WQC 3884 to allow greater than 40 feet of impact at the stream crossing location is requested. Original PCN Text: UT- Laurel Fork -P (S -1) will be permanently impacted by a 30 -foot long pipe for an access road and temporarily impacted by installation of a grade control structure and construction activities. UT- Laurel Fork -Int (S -2) will be permanently impacted by installation of a 25 -foot long pipe (replacing an existing 16 -foot long pipe) for an access road and temporarily impacted by stabilization of an eroded bank at the pipe outlet and construction activities. 4.

Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Modification Text: The proposed modification will result in 13 additional linear feet of permanent stream impact and 2 additional linear feet of temporary impact However, the proposed pipe length is the same 30 linear feet, it is the proposed headwall /retaining wall that results in the additional impact but this wall still allows for an open channel that will stabilize shortly after construction The intent of the modification will reduce overall impacts for the project in two ways First by utilizing the existing driveway, which will require only minor widening, a large area of new road construction will be eliminated Impacts avoided include almost a half acre of land disturbance and a 10 to 20 foot -tall 2.1 cut slope Second Utilizing the existing driveway addresses adjacent property owner concerns regarding aesthetics unrepaired impacts to their driveway and extra runoff from a second road. Original PCN Text: The proposed project has been planned from the beginning to avoid and minimize impacts to jurisdictional waters to the maximum extent practicable. The Applicant initiated an environmental consultant near the beginning of the planning stage for the project to perform a wetland delineation and advise regarding potential permit issues. Consequently, the project has been designed so that the vast majority of the land disturbing activities will be located in upland areas well away from any streams or wetlands. The only impacts are associated with utility line installation and maintenance access and two existing pipe upgrades required by NCDOT as a condition of the driveway permit The DOT pipe replacement impacts have been addressed in a separate application for a NWP -3 submitted to the USACE on May 14 2012 Utility Line Impacts: The Cottages of Boone project involves development activities on two tracts of land separated by a narrow corridor, through which the Applicant has obtained an easement All of the roads and buildings associated with proposed student housing are located on Tract 1 of the project Tract 2 was acquired primarily as a location for on -site water and sewer systems required to serve the development The easement will allow for access between the tracts for utility lines and associated maintenance access A small perennial stream (UT- Laurel Fork -P) flows through the narrow corridor separating Tracts 1 and 2 There is an existing driveway also located within this corridor and adjacent to UT- Laurel Fork-P. The easement connecting the Page 9 of 14 PCN Form — Version 1.3 December 10, 2008 Version two tracts, crosses both the driveway and the stream (Impact Site 1) and lines up with an existing woods road on Tract 2 that leads to the proposed W WTP. The existing woods road crosses a small intermittent stream (UT- Laurel Fork -Int) at Impact Site 2. Utilizing the existing woods road minimizes impacts by eliminating the need to construct a new access road across a sloping forested hillside. Constructing an access road around UT- Laurel Fork -Int would not be practically feasible because the steepness of the road would make it extremely difficult if not impossible to bring in the package W WTP and a pump station would be required for the sewer line. The location of the easement and crossing of UT- Laurel Fork -P was selected to maximize distance between a house and the easement while still allowing for usable access road to be constructed. No alternative locations are available that would not also have to cross this stream and in some locations would have to cross it twice. Impact Site 1: This crossing has been designed with dual 30" CMP's 30 -feet long with stacked boulder headwalls. This design was selected as the least impacting practicable alternative. A bridge was contemplated but construction of the abutments would have caused the driveway to be blocked for an extended period (unacceptable to owners) the construction would likely have impacted the stream due to proximity, and the cost was much greater. Temporary impacts to the stream channel will be necessary for construction a temporary pump -a -round diversion, and to install a log grade control structure just upstream of the proposed pipes. Impact Site 2: The existing crossing consists of an 8" by 16' long clay pipe that was installed many years ago This pipe has apparently become clogged or was overwhelmed at times and water flowed over the road creating a small gully in the road and a large gully with steep eroding banks below the road The crossing was in fact approximately 24 -feet long initially but two 4 -foot long sections of pipe broke off during the formation of the gully. In order to repair this existing crossing dual 24" CMP's 25 -feet long are proposed The eroded gully below the existing road will be stabilized with large boulders. Large boulders will also be keyed into the streambed to prevent scour below the proposed pipes Temporary impacts to the stream channel will be necessary for construction, a temporary pump -a -round diversion and to install keyed -in boulders below the pipes. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Modification Text: Extra erosion control measures will be used along the existing driveway within the trout buffer to minimize impacts to the maximum extent practicable throughout the construction phase At the completion of the period of intense use the buffer area between the driveway and the stream will be planted with trees and shrubs to enhance the quality of the buffer over what exists today. Currently the buffer consists of only mowed grass Original PCN Text: Permit conditions require that work be performed in the dry, therefore a pump -a -round system will be used at both impact sites (see detail). Work will be coordinated so that each instream activity will be completed in one day 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.
