Column 2a indicates it is permanent while column 2f indicates it is a temporary impact W4 is a permanent impact Section C 2 Wetland Impacts (PCN page 6) has been revised accordingly b Assuming W4 is a permanent impact the total wetland impact in row 2g (0 0874 acre) of the table does not equal the total impacts when summing up Column 2f seem (sic) to total 0 1052 acre Section C 2 Wetland Impacts (PCN page 6) has been revised accordingly c The temporary clearing wetland impacts (0 0486 acre) permanent fill or pipe wetland impacts (0 0231 acre) and permanent boardwalk wetland impacts (0 0157 acre) in 2h also totals 01052 acre and does not equal 0 0874 acre as indicated in row 2g Section C 2 Wetland Impacts (PCN page 6) has been revised accordingly d Please revise and resubmit Table 2 so that is (sic) portrays more accurate information Wetland impacts in PCN Section C 2 and riparian buffer impacts in PCN Section C 6 and Mr Danny Smith Supervisor January 10 2012 Page 2 of 3 attached Table 2 have been corrected and five copies of the revised table accompany this letter of response 2 Section C Table 6 — Buffer Impacts a Have buffer determination (sic) been conducted by DWQ? If so please provide a copy of the buffer determination letter If not please contact DWQ to conduct buffer determinations If you are conceding that all streams depicted on the Soils Survey of Wake County and /or ISGS topographic map (1 24000)are subject to the buffer rules then please label both the Soil Survey and USGS map with the same stream numbers that were used in Table 1(attached to the PCN application) for reference Martin Richmond has conducted field determinations on the six soil mapped streams that Robert .1 Goldstein & Associates believes are not subject to buffers On Jan 10 he sent the following email to Gerald Pattern Gerald —1 ve reviewed and I m putting together the topo and soils maps right now If you have project overlays on topo (or soils map) let me know and we 11 use yours for concurrence in the meantime 111 put together what 1 can and get this issued asap Thanks for your patience with this Martin On January 10 Mr Pattern sent the project corridor and stream crossing numbers on Topo and Soil base maps to Mr Richmond Upon receipt of the maps etc from Mr Richmond we will forward them to you b When totaling the buffer impacts in Table 2 (included in the PCN

proposed This activity does not require buffer mitigation nor does it meet the thresholds for stream and /or wetland mitigation You should contact the US Army Corps of Engineers to verify that mitigation is required for stream and wetland impacts James Shern at ACE advised us in Nov 10 that permanent stream and wetland impacts of Raleigh greenways will require mitigation Riparian buffer mitigation entries have been removed from the PCN 4 This office believes that the greenway in Zone 1 can be moved or reconfigured to avoid and minimize impacts to the riparian buffer The impacts to Zone 1 of the riparian buffer seem excessive based purely on the numbers but is not easily observable based on impact maps provided On November 28 2011 Lisa Potts of the City of Raleigh Parks and Recreation Department and the author met with Ms Lauren Witherspoon The purpose of the meeting was to review and discuss this specific comment We provided at that meeting supplemental plan sheets with aerial photography and reviewed each Zone 1 impact with Ms Witherspoon At the conclusion of this review Ms Witherspoon indicated that she was now satisfied that impacts to Zone 1 of the riparian buffer have been minimized 5 Please provide impact maps at 1 =50 scale Please note that of the impact maps provided Figures 2 5 were not included in the submittal Via an email transmission on December 14 2011 the author provided Ms Witherspoon with color coded plan sheets at 1 =50 scale depicting the impact in PDF Additionally and via the same a mail we also provided Figures 112 in PDF We understood Ms Witherspoon to imply that this submittal via e mail satisfied the requirement to submit hard cop13s of the impact maps and figures Please refer to a copy of the a mail transmission accompanying this letter In addition it appears Table 1 Potential Streams and Wetlands in the Honeycutt Creek Greenway Project Corridor may have been omitted from the original PCN submittal We provide five copies of Table 1 with this letter We appreciate the opportunity to reply to your review comments and believe that we have satisfactorily addressed each comment to your satisfaction If you need

efforts to minimize Neuse Buffer impacts D Impact Justification and Mitigation 1 Avoidance and Minimization 1 a Specifically describe measures taken to avoid or minimize the proposed impacts in designing project RJG &A delineated and mapped all streams and wetlands along the project corridor and consulted with City greenway planners and WSP Sells engineers during design to avoid and minimize wetland stream and buffer impacts wherever practicable Existing development and steep slopes pose tight constraints along much of the stream side corridor segments where riparian buffer impacts are unavoidable especially from Newton Rd to Honeycutt Park Between Newton Rd and Clear Brook Rd an existing cleared sewerline right of way will be used for some segments rather than clearing a new corridor through forested land farther from the stream Trail alignments in these areas were selected on a site by site basis considering proximity of the sewer to the stream bank stream bank stability riparian forest habitat quality adjacent wetlands availability of land beyond the zone 1 buffer connectivity with streets schools and parks and other site specific decision criteria The majority of the proposed 22 stream and 11 wetland crossings will use boardwalks or bridges (Type 1 Traditional Greenways and Type 3 Natural Trails) or existing sidewalks (Type 2 Wayfinding Segments) to avoid and minimize impacts There are only four areas where permanent fill or piping in wetlands is needed (total = 0 0409 acre) and four stream segments that require a permanent culvert and/or riprap (impacts ranging from 8 5 to 56 lin ft total = 1315 ft) based on the design engineer s determinations See also the attached Discussion of Unavoidable Impacts and Alternatives to Riparian Buffer Encroachment for site specific explanations of efforts to minimize Neuse Buffer impacts 1 b Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques Measures to avoid and minimize impacts to wetlands streams and buffers during construction include minimize clearing widths using existing cleared lands and sewerline rights of way for access and staging areas keeping equipment and stocked materials on the off stream side of the construction corridors and using modular or stick built bridges to minimize the size of vehicles needed in remote forested areas

informative as were the other presenters Just a reminder if I may to look at the colored 50 scale impact plan sheet we submitted last Thursday I am planning to take off the two weeks of Christmas and would like to get to you what you need before I leave Thanks From Witherspoon, Lauren [mailto lauren wtherspoon @ncdenr gov] Sent Thursday December 08, 20114 45 PM To Troutman, Ralph Cc Lisa Potts @raleighnc gov gpottern @rJgacarolina com Subject RE Color Coded Plan Sheet with Impacts, Honeycutt Creek Greenway I will try to look it over tomorrow and let you know what I think I am glad you emailed because I remembered that we never discussed (during our meeting) the need for you all to have buffer determinations for those streams that are depicted on the Soil Survey and /or USGS topo map but that Gerald determined not to be streams I mentioned it in an email awhile back and didn t want that to slip through the cracks Thanks Lauren 1 From Troutman, Ralph [mailto ralph toutman@wspsells com] Sent Thursday, December 08, 20112 57 PM To Witherspoon, Lauren Cc Lisa Potts @raleighnc gov, gpottern @ggacarolina com Subject Color Coded Plan Sheet with Impacts, Honeycutt Creek Greenway Lauren good afternoon and thank you for meeting with Lisa Potts and me on November 28 to discuss the City of Raleigh s Honeycutt Creek Greenway As promised I am sending you plan sheet C7 2 showing the greenway with buffer impacts We have endeavored to color code the impacts the same as they appear in our original PCN submittal although it does appear that my ignorance of AutoCAD does prevail in a couple of instances Nevertheless we hope this is what you are looking for to correlate the buffer impacts with the construction drawings Note that we have intentionally omitted some information such as topography hoping that this will allow you to focus better on the impacts Please look this over If you are satisfied with this please let me know and we will prepare the remainder of the construction plan sheet with impacts in like manner Looking forward to your presentation in the morning Ralph E Troutman P E WSP SELLS office 919 678 0035 cell 919 -422 5297 2 Table 1 Potential
