Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Construction activities will be limited to minor bank grading and bank stabilization, and will eventually reduce overall impacts to the lake ecosystem.

This letter provides a summary of the project site existing conditions, repair design, and supporting documentation for the enclosed PCN notification form. Oak Hollow Lake was constructed in the 1970's and is used for water supply and recreation. The project area is located on a semicircular shaped projecting point along the east side of the northwestern aligned arm (West Fork Arm) of the lake. A residential street, Jeffrey Lane Point, terminates within the projecting point and serves two single family residences located on the point. The City of High Point owns an area of land between the lakeshore and the private parcels exhibiting a variable width but generally 20+ ft. Ownership of this area allows the City to provide long term preservation of lakeshore line which enhances the protection of water quality for the water supply to City of High Point. The shoreline in this area has exhibited accelerating erosion, relative to other areas of the lake, along a length of approximately 200+ ft. for several years. The eroding profile exhibits significant undercutting at and just below the water level extending horizontally a distance of 2-5 feet underneath the overhanging shore. The profile of shore above the undercut transitions from near vertical at the water's edge to a gentle slope of 10-20 percent within 3-5 feet onshore. The water depth at the shoreline is approximately 12-18 inches. The overhanging shoreline is in the process of failing structurally due to bank rotation and mass wasting (see figure 1). This 9 a s ruc ura s ore a► ure a process is reducing the shoreline buffer Project site managed by the City and introduces sediment into the lake. F ure 1 Treefa 11 nd t t I h f 7 t Oak Hollow Lake Shoreline Restoration PCN Notification Letter Poge I 0 The proposed -design .project, -which is intended to repair the eroding shoreline and provide Yong term protection, includes installation of temporary 10' wide access road and vehicle turnaround extended from a nearby cul-de-sac. Approximately 40 trees will be removed for construction purposes, then approximately 285 linear feet of shoreline will be regraded and stabilized with either rip rap armoring or installation of a cellular confinement grid. The repaired shoreline will exhibit the same planform as currently exhibited. Ground cover will be established promptly on all disturbed areas and all work will conform to the latest edition of NCDENR's Erosion and Sediment Control Manual. Permanent vegetation consisting of native- trees and shrubs are proposed to, further stabilize the disturbed upland areas where trees were removed for construction. The enclosed PCN notification form and supporting documents are submitted on behalf of the City of High Point. Based on a phone discussion between Jesse Phillips, a Staff Engineer with Tetra Tech and David Bailey, the USACE manager for Guilford County on Tuesday January 9 we understand that the project as described will be covered under NWP 13, non -reporting. Thus, the project will be covered under NWP 13 but the project's environmental impacts are considered minor and therefore the city is not required to submit a pre=construction notification to the district engineer prior to implemerrtatton Please feel free to contact me if I can answer any questions or provide additional information.
