The permit requested approval for stream and wetland impacts related to the proposed site development activities in addition to proposing a plan to resolve a previously identified violation regarding unauthorized discharge (fill material) within existing site wetlands. Included in the PCN application were various supporting Construction Drawings, impact maps, etc. prepared by others. The project site is located approximately 4,000 feet west of the intersection of McConnell Road and McConnell Center Drive in Greensboro, NC. See the attached Figure 1- Vicinity Map. The NWP 39 and WQGC No. 4139 were subsequently issued by your offices on April 21, 2020 and April 13, 2020, respectively. As a condition of both permits a total of 1.58 acres of wetlands located within the bed of a previously existing pond on the site were required to be restored as described on the Wetland Restoration Plan (Sheet EXH WL 3 of the Construction Drawings) prepared by the Triad Design Group of Charlotte, NC. A copy of Sheet EXH WL 3 is attached as Figure 2. Page 1 of 4 Lot 9 McConnell Center— Wetland Restoration As -Built Report S&EC Project No. 13795.D2 Soil & Environmental Consultants, PA April 20, 2021 The purpose of this letter report is to summarize the completion of required wetland restoration activities, document as -built conditions of this area (as required by both agencies as conditions of the referenced permits) and provide additional detail regarding future monitoring activities including the proposed monitoring schedule. Construction Summary Based on our discussions with Mr. Goria we understand that a pre -construction site meeting was conducted on August 14, 2020 to review the Construction Drawings (prepared by the Triad Design Group of Greensboro, NC), discuss the proposed restoration activities and the schedule for the work. In attendance were the property Owner, the project design engineer (Mr. Allan Hill, PE of Triad Design Group), the development manager (Mr. Jason Smith of Windsor Commercial of Greensboro, NC) and the construction contractor (Mr. Taft Cables of Cable's Enterprises, LLC of Brown Summit, NC). The Wetland Restoration Plan sheet provides a Restoration Construction Sequence as well as Wetland Restoration Notes and Planting Plan which were utilized by the construction contractor while performing the restoration activities. Restoration grading was performed between August 18, 2020 and October 9, 2020 and included the removal of approximately 42,000 cubic yards of fill material from within the old pond bed and the grading of the adjacent slopes. After grading was completed the perimeter slopes and upland areas were stabilized in accordance with the requirements of the approved land disturbance permit. Stabilization of the restored wetland area was performed on March 8, 2021 by Sides Seeding & Erosion Control of Lexington, NC, and included hydroseeding the area with a wetland seed mix and temporary seed. Where necessary hand application of the seed mix and straw mulch were applied. The wetland seed mix utilized is provided in Attachment 1. NOTE: Based on our discussions with Mr. Goria we also understand that the existing pond dam was breached on December 11, 2020. At that time, the riser/barrel spillway was removed, and the breach channel was lined with riprap and surrounding disturbed area were stabilized with temporary/permanent seed (and straw mulch applied) and select other temporary erosion control measures near and within the pond were also removed, all in general accordance with the Pond Breach Plan. Sheet EXH WL 4 of the Construction Drawings is attached as Figure 3. Based on recent discussions with the project design engineer we understand that the wetland restoration construction, the dam breach, and the associated stabilization of the disturbed areas were performed in general accordance with the design intent and the approved permit documents. As -Built Survey & Photo Documentation As described on the Wetland Monitoring Plan on Sheet EXH WL 3 the as -built survey for the restoration work must include photo point documentation from a minimum of three (3) photo Page 2 of 4 Lot 9 McConnell Center— Wetland Restoration As -Built Report S&EC Project No. 13795.D2 Soil & Environmental Consultants, PA April 20, 2021 points within the wetland restoration area and a plan view diagram of the restoration area (and surrounding vicinity). Details regarding each of these requirements is described below. Following the completion of construction, in coordination with S&EC, the property Owner installed three (3) photo points within the wetland restoration area to allow for future site monitoring. The location of each photo point is identified in the field with steel T-post (painted orange for ease of location). Post -construction field survey data for the wetland restoration area (including the location of the photo points) and the immediately surrounding vicinity was collected by Borum, Wade & Associates, PA of Greensboro, NC. This survey data was utilized to prepare the Topographic Survey Map (As -Built Survey Map) dated April 16, 2021. See Figure 4 attached. The photo points are numbered PNT#1, PNT#2 and PNT#3 and are shown on Figure 4. On March 12, 2021 S&EC visited the project site to observe post -restoration site conditions and collect as -built site photographs at each of the three (3) photo points. While on site we took multiple photos, in varying directions, at each of the three established photo points to document as -built conditions. The locations and approximate directional orientation of each of these photos are shown on the attached Photo Point Map (see Figure 5). See Photos 1 through 9 in Attachment 2. The same photo points (and directional views) will be used in future monitoring reports to allow for the required year-to-year comparison of site conditions within the wetland restoration area. An additional photo was taken at a location upslope of each of the three photo points to provide a general perspective reference for the location of each of the three photo points within the restoration area and document overall site conditions at the time of our visit. See photos 10 through 12. Photos 13 and 14 provide a view of the breach channel from upstream and downstream, respectively. Based on recent discussions with Mr. Goria we understand that the wetland restoration area and its surrounding vicinity have continued to stabilize with vegetative cover. Post -restoration Monitoring As a condition of the USACE and DWR permits monitoring of the wetland restoration areas is required for a period of three (3) years following the completion of the required restoration activities or until such time that both agencies determine that the restoration area can be discontinued. S&EC will perform monitoring visits twice per year (in March or April, and again in August or September) as required by USACE and DWR permit conditions and as described in approved Wetland Monitoring Plan on Figure 2 (Sheet EXH WL 3). Site monitoring will be qualitative in nature and will include a general visual assessment of the overall stability of wetland restoration area and the immediately surrounding slopes and upland areas. A visual assessment of wetland planting success will be made within the vicinity of each photo point. As required in the Wetland Monitoring Plan monitoring photos will be taken at each of the photo points for comparison with those from the preceding monitoring years. Page 3 of 4 Lot 9 McConnell Center — Wetland Restoration As -Built Report S&EC Project No. 13795.172 Soil & Environmental Consultants, PA April 20, 2021 Monitoring reports will be submitted to USACE and DWR not later than December 31' of each monitoring year and include the information described in the Monitoring Report Guidelines shown on Sheet EXH WL 3. A copy of the guidelines is provided as Attachment 3. Please contact us if you have any questions or comments regarding this letter.
