K. Roden Reynolds@usace.army.mil> Subject: RE: Drummond Place Good Afternoon Sue, Please find the below responses and attachments on behalf of the applicant. Please let me know if you require additional information. Thanks. DWR Comment 1): Please provide an overall plan sheet C1 that shows all Jordan Lake buffers. Please identify building envelopes and drainfield limits on any lots with buffers to ensure that lots are buildable without further disturbance to the buffers. Please note that deed notifications will be required on all lots with streams, buffers or wetlands present. Applicant Response: Please see attached sheet C1. The applicant acknowledges the general condition requirements that deed notifications are required on all lots with streams, buffers or wetlands present. DWR Comment 2): The Jordan Buffer Rules table of uses states that road crossings are exempt if less than 40 linear feet of stream is disturbed. It does not specify permanent versus temporary disturbance. Since more than 40 feet of disturbance will occur for the installation of the culvert and riprap pad, please revise the PCN to include a buffer authorization request, and fill out the buffer impact table. Applicant Response: Please find the attached updated PCN that includes allowable without mitigation impacts to riparian buffers. 1 DWR Comment 3): The requirement for diffuse flow of stormwater into the buffer is applicable to the entire site/project, not just the utility maintenance road. Please provide a diffuse flow plan that clearly shows how stormwater from Drummond Estates Dr and Harthill Dr, as well as stormwater from impervious surfaces on individual lots (driveway, roof drains etc) will be managed. Applicant Response: Following discussions with Division stormwater representatives, the applicant has designed scour pools at the discharge point of concentrated stormwater flow into the riparian buffer. The attached drawings include the calculations utilized for design of the scour pools. Please note that the use of scour pools to meet diffuse flow requirements will result in permanent impact to Zone 2 of the riparian buffer. As such, the applicant has amended the attached PCN to request buffer authorization for the proposed scour pools. Changes to the PCN outside of Section C.6 have not been made. Sincerely, Bradley S.

Comments: The proposed project will unavoidably impact riparian buffers associated with the road crossing, utility crossings and to maintain diffuse flow requirements of the site. The attached table outlines the proposed impacts that are allowable without mitigation. The utility line crossings have been designed in a manner that is an exempt activity and authorization for these impacts are not being requested. Mitigation is not proposed for the unavoidable impact to riparian buffers. D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The road crossing location was selected in an area of stream that is relatively straight with few meanders. The applicant has further demonstrated avoidance and minimization of stream impacts by proposing to construct approximately 2.5 feet tall culvert head/end walls and utilize 2:1 road side slopes. Furthermore, the Applicant has designed rip -rap stabilization measure to be keyed into existing grades of beds and banks to 30 linear feet of stream channel. The remainder of the larger residential subdivision has been designed to avoid impact to WoUS and Lake Jordan buffers. There are approximately 2,500 linear feet of perennial stream channel and 1.5 acres of wetlands located on the site. The site has been designed to avoid approximately 1.44 acres of wetlands and 2,430 linear feet of perennial stream. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The clearing limits will be staked and silt fence will be used. Temporary coffer dams will be installed upgradient of the proposed culvert and sewer line trench. During construction, water will be pumped around the construction footprint. Appropriate stream bank protection will be provided in the channel during construction and all excess excavated material will be immediately removed from the stream bank crossing area. The top 1 foot of stream bed material will be stored in upland areas and used to backfill the top 1 foot of the excavation trench for the sewer line crossings. Upon completion of the culvert/utility line installation, the temporary sand bag coffer dams will be removed and flow will be diverted through the culvert or across the sewer lines. Disturbed banks will be restored to similar pre -construction conditions, matted and seeded/live staked. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.

E] Raleigh 5c. If yes, indicate the USFWS Field Office you have contacted. ❑ Asheville 5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? The USFWS List of federally protected species for Forsyth County identifies: Bog turle (T=S/A , NLEB (T) and small- anthered bittercress (E). Based on our site observations, suitable habitat for the bog turtle and small anthered bittercress are not located on the site. Suitable summer roosting habitat for NLEB is located on the site. However, the site is not located within 150' of known summer roost trees or 1/4 mi of known hibernacula. Therefore, the applicant will rely on the final 4(d) rule for NLEB and removal of suitable summer roosting trees should not be restricted. 6. Essential Fish Habitat (Corps Requirement) 6a.
