This additional wetland impact is for the installation of a water line along Trailwood Drive. The impacts are temporary and the area will be returned to grade and reseeded with a wetland seed mix. The wetlands in this area are not forested, but rather maintained herbaceous wetlands between an existing overhead power line and the greenway bridge. We ask that you add these impacts to those already requested in the PCN application. These should answer questions 1 & 2 below. (PS ... Good catch George. Sorry we missed it.) As to question No. 3, the reason our sketch map looks different from the impact maps is that the sketch map was simply an approximation of the potentially jurisdictional wetlands in this area. We found other consultant flags on site while performing our delineation, researched it and discovered that the City of Raleigh had just recently permitted the Walnut Creek Greenway (TIP NO. C-5604-OC) project in this area. We obtained the verified, survey located potential wetlands from the City and the project engineer used those in the preparation of the impact maps that we provided in our package to ensure consistency between the two projects. I was not provided the SAW# for the City's greenway project, but was able to download the NCDWR No. 2019-1273 file. This City greenway trail has nothing to do with our apartment complex project, but again we just wanted to be sure that there weren't two different delineations used when one was still valid. Hope that makes sense. I should also note that we are not looking for a JD to be issued along with our permit verification request (in case that matters any). Please don't hesitate to let me know if you need anything else. Thanks!

Bob Zarzecki Wetlands Department Manager Soil & Environmental Consultants, PA -----Original Message ----- From: Phillips, George L CIV USARMY CESAW (USA) <George.L.Phillips@usace.army.mil> Sent: Friday, January 31, 2020 11:45 AM To: Bob Zarzecki <bzarzecki@sandec.com> Cc: stephanie.goss@ncdenr.gov Subject: Trailwood Apartments, SAW-2020-00151, Incomplete Application :.• I have reviewed the PCN for the above referenced project, and I have a few comments/questions that need to be addressed prior to proceeding with issuance of the permit verification. 1. Based on the information provided in your impact maps it appears that the proposed 12" water main results in wetland impacts near Trailwood Drive between the proposed buildings and Walnut Creek. Please provide an exhibit depicting the impacts and update the PCN accordingly. 2. It appears that the 12" water main crosses Walnut Creek near Trailwood Drive. Please provide an exhibit to depict the crossing. If there are impacts to jurisdictional features please provide an exhibit depicting the proposed activities and the update the PCN accordingly. 3. The wetland depicted near Avent Ferry Road does not accurately match the wetland boundary depicted on "Figure 3 - Sketch Map". Please update the impact maps to correctly depict the wetland as delineated. If impacts to jurisdictional features change due to the changes in the wetland boundary please provide an updated exhibit depicting the impacts and the update the PCN accordingly. I will continue to process the application but at this time it is considered incomplete. Please provide the additional information to move forward. Please let me know if you have any questions. G.
