Below are the responses to the questions that you had before. We have provided supporting documentation when appropriate via this Sharefile link: https://stewart- eng.sharefile.com/d-s2d58cOd82d54de58. Please use the link to download the information in response to each question below. We have updated our drainage and pipe network from what has previously been submitted showing dewatering streams to avoid a retaining wall to now new pipes that will go under the retaining wall and keep the streams in the same location without dewatering channels. The flow rate is very small for each of these streams and our plans already have sequencing in the notes that state if there is an active flow that an impervious dike be construction and the pipes be replaced in a day. A temporary pump around will not be required. 1. Based on our site visit (week of April 27', 2017) and field work completed by Owen Carson at Equinox Environmental, impact sites S2, S3, S4, and S5 involve jurisdictional streams (i.e. at least intermittent flow). DWR is good with the proposed plan for S2 and S5. Additional clarification is needed for S3 and S4. The proposed plan for S3 is to divert flows approximately 150 -linear feet along the greenway trail and discharge the flow via an 18 -inch pipe. The proposed flow diversion would dry up the baseflow in the existing receiving channel of S3 for an undermined length of channel. The permit application impact table would need to include the dewatered channel length as an impact if this proposed drainage plan is maintained. Please either update the impact table or modify the proposed plan. S3 is currently coming out of an 8" diameter corrugated metal pipe (CMP), approximately 17 -ft long, that is in poor shape with an inlet that is buried below grade along our alignment-L3REV- based on survey data and field investigations by Equinox. We will be installing a 24" reinforced concrete pipe (RCP) parallel to the existing 8" CMP pipe and grading the outlet to maintain the existing channel downstream. The 8" CMP will be removed after the 24" RCP has been installed. STRONGER BY DESIGN 421 FAYETTEVILLE ST. RALEIGH, NC T 919.380.8750 SUITE 400 27601 F 919.380.8752 Responses/Additional Information - Beaucatcher Mountain Greenway Trail - DWR 2016-1263 September 28, 2017 Page 2 The replacement pipe will be 27 -ft long as we will need to daylight further down the hill because of a proposed retaining wall. The elevation of the proposed 24" RCP will be lower than the existing 8" CMP to accommodate the footers on the retaining wall. There is another existing pipe that is a 15" CMP, 22 -ft long just uphill that crosses our alignment-L1REV-. We will be replacing that pipe in place with a 24" RCP that is 38 -ft long and will tie to a drainage structure and drop inlet above our trail to catch any water that is coming down the hill. We will tie the two new pipes into the same drainage structure (24A) and have a drop inlet to catch any surface water at the intersection of the two trails. In this way, we will be controlling the water velocities coming down and across our corridor as well as cleaning up the area. Given that there isn't any adequate aquatic passage with the existing pipe system and that there is not a true existing upstream channel on the mountain (only the small existing ditch beside the old roadbed), we are not proposing any aquatic passage and would like an exemption/exception for this requirement on S3. S4 is currently coming out of an 18" diameter corrugated metal pipe (CMP) that approximately 28 -ft long. Based on survey data and field investigations by Equinox, Stewart understands there is no existing defined upstream channel on the mountain (only the small ditch adjacent to the existing roadbed). There does appear to be a swale on the mountain above (just below the-L1REV- trail roadbed), but the contours flatten out and the runoff appears to return to sheet flow above the 18" culvert. We will be replacing the 18" CMP with at 28 -ft long reinforced concrete pipe (RCP) and grading the outlet to maintain the existing channel downstream. Please contact myself if you have any questions or need any additional information. We look forward to your response and to moving the project forward to construction.
