27699 1548 r Meehne Purpose This was the seventh meetmg in the NEPA/404 Merger Process for R 3620 The � purposc of the meetmg was to review the 30°/a hydraulic plans as part of Concurrence J Point 4B The initial CP 4B meetmg was held on July 20 2011, but since the agencies had concerns regardmg the proposed use of 4 1 sidc slopes in wetlands a second CP 4B meetmg was held Discussion • Bill Biddlecome opened the meeting with an introduct�on of attcndees Knstine O Connor bnefly reviewed the pro�ect history since the last CP 4B meeting includmg the proposal by NCDOT to use 4 1 side slopes m some wetland areas, as opposed to the 3 1 side slopes that had ongmally been proposed and concurred upon as an avoidance and mimmization measurc as part of CP 4A At the time that the CP 4A concurrenc.e form was s�gned, however the final fill height of the new facility had not yet been determined and NCDOT did not know what the updated wetland and stream tmpacts would be at that point At the previous CP 4B meetmg on 7/20/11 NCDOT s Roadway Design & Hydraulics Units had proposed the use of 4 1 side slopes between Stations 12+00 and 44+80 L and Stations 90+00 and 119+00 in order to avoid the use of guardrail • Knstine noted that the last quantified wetland impacts were calculated at the CP � 3 — LEDPA meetmg At that time Alternahve 1 was determined to have 19 3 acres of wetland impacts which mcludes a 25 foot offset of the slopes stakes Currently, the wetland impacts for Alternative 1 with 3 1 side slopes and guardrail are shown as 11 3 acres while the use of 4 1 side slopes without guardrail would result tn wetland impacts of 11 9 acres Both of these updated numbers were calculated using a l0 foot slope stake offset • Gary Lovenng went through the matenals from AASHTO s 2004 A Policy on the Geometnc Design of Highways (the Green Book) and the 2002 AASHTO Roadside Dcsign Guide that he had provided to thc Merger team pnor to the meeting regarding the safety issues related to the use of guardrail, particularly on two lane facilities He also noted that though NCDOT would not be using 3 1 side slopes in all wetland areas mimmization was still done on this pro�ect by ad�ustmg the profile of the roadway to minimize the fill he�ghts with respect to the groundwater Fill heights were held to 4 feet above the ex�stmg grade • Steve Cummings expressed concern about the relocation of utility poles that were designed to be placed directly behmd the guardra�l Gary confirmed that these poles would have to be placed�ust outside the edge of the 30 foot Clear Recovery Zone Gary noted that he didn t think there were any existing power poles that would be ad�acent to the proposed road but that there may be an existmg crossing which should not be affected by the proposed change to 4 1 s�de slopes J ■ � � • Both Travis Wilson and Bill Biddlecome stated that they found the use of 4 1 side slopes acceptable and suggested that NCDOT should revise the CP 4A concurrence form after removing the commrtment to use 3 1 side slopes m all wetland areas Bill cautioned NCDOT to avoid a blanket commitment to use 3 1 side slopes m all wetland areas m the future this will hopefully prevent revisions to the onginal CP 4A commitments agreed upon by the Merger team Concurrence • The team agreed to remove the commitment regarding the use of 3 1 side slopes m all wetland areas from avoidance/minimization measures on the CP 4A form and resigned rt Conclusion � • Concurrence among attending team members was achieved Achons to be completed by NCDOT before the CP 4C meetmg include ➢ Obtain concurrence on the revised CP 4A form from all Merger team members who did not attend • If any recipient of the meeting minutes would like to add comments or feels that a comment is erroneous or needs to be expanded please feel free to contact Knshne O Connor by phone at (919) 707 6034 or by email at kaoconnor c�i,ncdot gov � r 1 � I r � � i � Wainwright, David From:

Good morning everyone, ' I hope you've all received the notification regarding the second R-3620 48 meeting to be held on October 20, 2011 at 10:45 AM. In preparation for this meeting, I've coordinated with Hydro and Roadway to provide you some additional informatioh regarding wetland impacts and the use of guardraiL After recalculating the wetland impacts based on both a 3:1 side slope scenario (with guardrail) and a 4:1 side slope scenario (without guardrail), our new impacts are as follows: 3:1 (with guardrail) - 11.3 acres 4:1 (without guardrail) - 11.8 acres Keep in mind that these impacts include all the fill, excavation and mechanized clearing that will take place in the wetlands. An offset of 10-feet from the slope stakes was used for these calculations. Please note that 'these numbers are a good bit lower than our previous estimate of 19.3 acres of wetland impacts as included in the FONSI. Also attached to this email are two files from AASHTO design manuals (the Green Book and the Roadside Design Guide) that provide some information regarding the use of guardrail. If possible, please review these materials prior to the 10/20 meeting and let me, Gary, or Galen know if you have any additional questions or requests. Thank you, Kristine Kristine A. 0'Connor, P.E.

Bridge perepets or raiLs are eovered in MSHTO design criteria and specificarions for highway bridges. LongiNdinal i �� � bartiers are generally denoted as one of three types: flui6le, semirigiQ or ri8d. The major �}�, differe�ce benveen these types is the amowt of barrier deflecbon thaC tekes place when lhe i_ I'� barrier is struck. it I' ; I Flexible baerier rystems undergo considereble dynamic dcilection upon impact and gene`ally �; � ! impose lower'uupact forces on the veAicle than semirigid and rigid sys[ems.7'he resistance of this system is derived from tensile force in the longitudinal member. WitLin tha impact zone, the "-�� �' cable or beams tear away from the support post upon impact; Ihus, the post offers negligible �� ` � resistance. Howeveq the posts outside the impact zonc provide sufficient resistance to keep the �' 'y� deflection of the longitudinal member within an acceptable limit. This system is designed � �I primarily to wntain rathtt than redimet t6o vehicle and nceds more lateral cleerance from fixed � objects due to the detlection during impact. � I ` � I , 331 ; � � Is1 _ ' al .. � /1ll�IIII(/[�l/fflnlfll�HiY/(�.1'f(�fffl�f\' TABLE 7.1 Flrst hermtul event tixetl-obJect fetallties by oEjeet rype FDCED YEAR OBJECT L993 1994 1995 1996 1997 1�8 IY99 .
