The Total Project Area reported in Section IV.7 of the application (444.6 acres) must be the low density drainage area. For purposes of calculating density, you may not include coastal wetlands (1.9 acres) or the area of surface waters (5.7 acres). If you have to have 4,706,117 sf of BUA, the Total Project Area reported in Section IV.7 will need to be 450.2 acres or more and the Total Property Area reported in Section IV.4 will have to be at least 457.8 acres. So you'll need to either reduce the proposed BUA to 4,648,026 or add another 5.6 acres to your project area. In order to make the numbers work, the added 5.6 acres should not contain coastal wetlands or surface waters. Please make the necessary changes to the numbers on page 2 of the application and resubmit that revised page. I can accept a scanned electronic copy via email. If you expand the drainage area, be sure to send me 2 copies of the new purple and yellow shaded "overview" sheets that show the new low density drainage area boundary.

Linda NCDENR North Carolina Department of Environment and Division of Water Quality Beverly Eaves Perdue Coleen H. Sullins Governor Director January 21, 2010 Carl Baker, Public Works Officer USMCB Camp Lejeune 1005 Michael Road Camp Lejeune, NC 28457 Subject: Request for Additional Information Stormwater Project No. SW8 090630 Base Entry Road P-1382 Onslow County Dear Mr. Baker: Natural Resources Dee Freeman Secretary The Wilmington Regional Office received an Express Stormwater Management Permit Application for Base Entry Road P-1382 on January 13, 2010. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: The total project area reported in Section IV.7 of the application, excluding the coastal wetlands and surface waters, is 417.2 acres, which equates to 18,173,232 square feet. However in Section IV.10, the low density overall drainage area is listed as 19,697,229 square feet, or 452.186 acres. The total property area listed in Section IVA of the application is only 424.8 acres. Where does the extra 27.386 acres come from? If the 417.2 acre project area is correct, the maximum amount of built -upon area that can be permitted for overall low density is 4,361,576 square feet, but the application requests 4,706,117 square feet. 2. It appears that the permanent pool surface area and permanent pool volume for each pond reported on the supplement form do not include the forebay. The surface area of the forebay and the forebay berm at the permanent pool elevation is intended to be counted toward the required minimum surface area. The volume of the forebay, from the top of the sediment removal elevation up to the permanent pool elevation is also intended to be counted as permanent pool volume. I usually ignore the forebay at the beginning of the design phase, estimate an average depth and simply draw a permanent pool contour on the plans such that the required surface area is provided. Then, I calculate the permanent pool volume and the required minimum forebay volume, and check the estimated average depth. If needed, adjustments are made. Then, one positions the forebay berm and adjusts the contour in the forebay such that the minimum required forebay volume is met or exceeded. The volume taken up by the forebay berm is not considered. 3. Because the forebay surface area was not included, the average depth calculations are off. The forebay is included in the average depth calculation, so that the "average" is a true average that accounts for the shallower forebay. Please refer to Figure 10-2b in the BMP Manual.

Because the permanent pool volume doesn't include the forebay, the provided forebay volumes are a little below the required range of 18%-22% of the provided permanent pool volume. 5. Please modify the trash rack detail on sheet SWM-7 to specify that no opening is larger than 6 inches square. 6. The orifice size must be based on using only the calculated minimum 1.5" design volume, not the volume actually provided in the pond as the temporary pool volume. Since the design volume and the temporary pool volume are relatively close, it is not much of an issue and should not cause a change in either orifice, but the orifice calculations need to be revised to use the correct volume. 7. Please add the total number of required plantings for each vegetated shelf to sheet SWM-8. The requirement is 50 plants for every 200 square feet of shelf area. For example, I calculated a shelf area of 3,500 square feet in Pond A-1, which equates to 875 plants for that shelf. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior -to January 28, 2010, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail, email or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. Please note that a second significant request for additional information may result in the return of the project. If that occurs, you will need to reschedule the project through the Express coordinator for the next available review date, and resubmit all of the required items, including the application fee. The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.

Ar j mesd Form Rewsed IOVN 02 ;_- Stormwater Application No. SW8 090630 Request for Additional Information Response to Comments The following comments were received on January list regarding the New Base Entry Road at Camp Lejeune, North Carolina. The following revisions have been made to the plans and calculations in response to the comments received. Please note that the stormwater management sheet numbers have been revised in order to fit into the larger set of construction plans for the entire project. The sheet number revisions are as follows: Original Sheet Number S►NM-1 SWM-2 SWM-3 SWM-4 SWM-5 SWM-6 SWM-7 SWM-8 Revised Sheet Number H-511 H-512 H-513 H-521 H-522 H-523 H-531 H-532 1. The total project area reported in Section IV.7 of the application, excluding the coastal wetlands and surface waters, is 417.2 acres, which equates to 18,173,232 square feet. However in Section IV.10, the low density overall drainage area is listed as 19,697,229 square feet, or 452.186 acres. The total property area listed in Section IVA of the application is only 424.8 acres. Where does the extra 27.386 acres come from? If the 417.2 acre project area is correct, the maximum amount of built -upon area that can be permitted for overall low density is 4,361,576 square feet, but the application requests 4,706,117 square feet. Total Property Area, Project Area and the Low Density Drainage Area have been retabulated as follows: IV.4 - Total Property Area should be 452.2 Acres 1V.5 - Remains 1.9 Acres I V.6 - Remains 5.7 Acres 1V.7 - Total Project Area should be 444.6 Acres IV.8 -Remains 23.9% IV.10 - LD Drainage Area Total Drains a Area remains 19,697229 sf On Site Drainage Area remains 19,697,229 sf Proposed Impervious Area should be 4,628,659 sf Impervious Area (total)remains 23.9% On -site Streets remains 827,633 sf Future (sf) should be 3,801,026 sf RECEIVED JAN 2 7 2m BY: 2. It appears that the permanent pool surface area and permanent pool volume for each pond reported on the supplement form do not include the forebay. The surface area of the forebay and the forebay berm at the permanent pool elevation is intended to be counted toward the required minimum surface area. The volume of the forebay, from the top of the sediment removal elevation up to the permanent pool elevation is also intended to be counted as permanent pool volume. I usually ignore the forebay at the beginning of the design phase, estimate an average depth and simply draw a permanent pool contour on the plans such that the required surface area is provided. Then, I calculate the permanent pool volume and the required minimum forebay volume, and check the estimated average depth. If needed, adjustments are made. Then, one positions the forebay berm and adjusts the contour in the forebay such that the minimum required forebay volume is met or exceeded. The volume taken up by the forebay berm is not considered. The permanent pool surface area and volume has been revised to include the forebay. Revised BMP supplement forms detailing the revision are included. 3. Because the forebay surface area was not included, the average depth calculations are off. The forebay is included in the average depth calculation, so that the "average" is a true average that accounts for the shallower forebay. Please refer to Figure 10-2b in the BMP Manual. The average depth calculations for both basins have been revised to include the forebays. 4. Because the permanent pool volume doesn't include the forebay, the provided forebay volumes are a little below the required range of 18%-22% of the provided permanent pool volume. Basin A 1- The forebay berm for basin A 1 was moved 2' in order to meet the volume requirements. A revised grading plan, basin cross section, BMP supplement form and revised area and volume calculations are included. Basin A2 - The forebay berm for basin A2 was moved 5' in order to meet the volume requirements. A revised grading plan, basin cross section, BMP supplement form and revised area and volume calculations are included. 5. Please modify the trash rack detail on sheet SWM-7 to specify that no opening is larger than 6 inches square_ The sheet has been revised to show 6" between the bars in the trash rack in each direction. In addition note 4 has been added to the sheet requiring the maximum opening in the trash rack to be 6" square. ` JAN 2 7 2010 D B G. The orifice size must be based on using only the calculated minimum 1.5° design volume, not the volume actually provided in the pond as the temporary pool volume. Since the design volume and the temporary pool volume are relatively close, it is not much of an issue and should not cause a change in either orifice, but the orifice calculations need to be revised to use the correct volume. The orifice draw down calculations and BMP supplement farm have been revised to calculate the dewatering time based only on the minimum required water quality volume. 7. Please add the total number of required plantings for each vegetated shelf to sheet SWM-8. The requirement is 50 plants for every 200 square feet of shelf area. For example, I calculated a shelf area of 3,500 square feet in Pond A-1, which equates to 875 plants for that shelf. The total number of plantings for each BMP has been added to the sheet (See Note 4 in the "planting specifications'). A signed and sealed revised sheet has been included.

Introductions were made around the room and for those who telephoned in from Morehead 2. Jesse Barker presented the project and its purpose — to reduce congestion, improve access to and from base, improve base security following 9/11, and accommodate grow the force initiative. A second access point will decrease pressure on the existing main gate. 3. Project will be phased over three years and will be built to NCDOT standards a. Phase 1— From Bell Fork Road at Rte 24 to Brewster Blvd -- including road widening at Brewster Boulevard (August 2010) b. Phase 2 — from Stone Street to Sneads Ferry Road (March 2011) c. Phase 3 — from Brewster Blvd. to Stone St. and off -base interchange at Rte 24 (2012) 4. Allen Conger presented current information on permitting effort a. Draft EIS will be released for public comment next month i. DEIS covers approx. 75 projects on Camp Lejeune, USMC Air Station New River, and Cherry Point — the new gate and access road is only one project of many ii. ROD anticipated in January 2010 b. Have incorporated changes to improve avoidance and minimization of impacts to natural resources following presentation of project to Joanne Steenhuis and Richard Spencer c. The USACE agrees with all wetland calls shown on the plan. In addition to these, some coastal wetlands have been delineated by design team. d. CWA Section 404 permit and 401 Water Quality Certification permits will address the entire new road, gate and road widening and the application will be submitted by November 2009 — the applicant needs all permits by March 2010. The second and third phases will likely be permitted as "corridor" impacts; however, the impacts areas likely will be very close to the final design impacts. 5. Once the project was presented to the group, the floor opened for discussion. The following is a recap of those discussions and list critical issues considered/discussed: o Georgette Scott (GS) indicated it would be ok to use a hybrid approach to stormwater BMPs, combining NCDOT's stormwater BMP manual and DENR's stormwater BMP manual as appropriate_ o Linda Lewis (LL) suggested that a project boundary be selected to meet tow density requirements. MEMORANDUM o LL: indicated that if the design team chooses to use 46' depressed median, the median can be used for stormwater treatment. Use structural BMPs at collection points such as bridges and curbed sections. o LL wanted to know if this project will impact any existing stormwater permits. Christine Nelson and Dan Sams said it would be best to avoid sharing BMPs with other existing and proposed developments an base. The design team agreed. o GS suggested showing project boundaries for all permits in the corridor o Dan Sams indicated that borrow pits will be a Land Quality issue. Best to use locations on base and not get into mining permits. If a borrow pit will be converted to a water quality pond/feature, then it must meet DWQ requirements for such. If borrow pits will not be used for stormwater treatment, Molly Ellwood (ME) said they want to see 3:1 side slopes and have bare areas replanted with native grasses. o ME asked how multipurpose trail will cross creeks. Will it cross at same elevation as bridges? Design team said that the trail will be incorporated as part of the bridge design and will cross at the same elevation as the bridges. o Steve Rynas suggested that LAMA consistency reviews might be phased like the rest of the project. However, the design team believes the coastal zone certification can be fully addressed in the Section 404/401 permit application. o LL asked about the existing and proposed cross section of Brewster Boulevard. It is currently a two lane road which is proposed to be a four lane road, both with no curb and gutter and sheet flow off edges. Dave Towler indicated there may be some crossing of existing stormwater permits at access roads off Brewster. o LL said DENR prefers not to have a full set of DOT design plans —much fewer sheets are preferred, such as: ■ Master sheet showing where typical sections begin and end ■ Location and type of BMP ■ Details o GS said that DWQ can provide design team with a list of required sheets and what information should be shown on those sheets so that DWQ can perform their review. Design team suggested burning a CD with pdfs of all the stormwater design information in addition to hard copies submitted for review. o Brynn Ashton asked about the next steps to expedite pre -submittal meetings in preparation of the express review process. Janet Russell will forward the forms to Jesse Barker who will distribute among the stormwater design team. o Express review team will likely consist of Mary Jean Naugle, Linda Lewis, and Christine Nelson. Process will take 30 days from time of submittal of a complete application. Pre - application meetings will be held to ensure everything is addressed. Min MEMORANDUM OR o DENR would like to seethe stormwater permitting for this project submitted in phases through the express permitting process. o Land Quality review will take 30 days once complete application is received. No express option for erosion control.

The project includes the construction of approximately 6.5 mile roadway 4-lane corridor spanning from Bell Fork Road at NC24 to Sneads Ferry Road and includes four major interchanges and three bridges spanning waterways. The project also includes the construction of a new base entry gate and the widening of Brewster Boulevard. The road will be designed based on NCDOT design standards. Excluding the planned interchange with NC24, the project is planned to be constructed on property owned by the US government on land that is mostly previously undeveloped. The following provides details regarding the property on.which the proposed project is planned for construction: Street Address, city, county— New Base Entry Roadway, MCB Camp Lejeune, Onslow County, NC Acres in Tract — to be determined when project boundary is set to allow low density stormwater permitting option Ownership Information from NCSecretary of State Web Site— US Government Property Tax Parcel ID number — US Government Property The project is planned to be phased over three (3) years and be designed and constructed in three (3) phases. The following lists each phase along with the planned construction year in parenthesis: Phase 1— From Bell Fork Rd. at Rt. 24 to Brewster Blvd., including road widening at Brewster Blvd. (August 2010) Phase 2 — From Stone St. to Sneads Ferry Rd. (March 2011) Phase 3 — From Brewster Blvd to Stone St. and off -base interchange at Rt. 24 (2012). The project site is located in Onslow County, North Carolina and is in the White Oak River Basin. The roadway drains to three main receiving waters: Northeast Creek, Wallace Creek, and Bearhead Creek. The following table lists each stream with its DWQ Classification. Stream Name DWQ Classification DWQ Index Northeast Creek SC NSW 19-16-(0.5) Wallace Creek SB NSW 19-20 Bearhead Creek SS NSW 19-20-1 This project has been included in Grow the Force initiative planning process including a total of approximately 75 projects planned at various site throughout North Carolina including Camp Lejeune, USMC Air Station New River, and MCAS Cherry Point. A Draft Environmental Impact Statement (DEIS) has been prepared for these identified projects. The DEIS is planned to be released for public comment in July 2009. A Record of Decision (ROD) is anticipated in January 2010. The USACE and DWQ have reviewed wetland and stream delineations shown on the plans and has concurred with the delineation. In addition, coastal wetlands have been delineated by the project team._ A DCM determination is taking place this month concerning verification of these determinations and the Stormwater Narrative Page 1 The USACE and DWQ have reviewed wetland and stream delineations shown on the plans and has concurred with the delineation. In addition, coastal wetlands have been delineated by the project team. A DCM determination is taking place this month concerning verification of these determinations and the Section 10 waters within the project corridor. Stream and wetland impacts will be permitted for the entire project through the Army Corps of Engineers (ACE). A 401/404 application is planned to be submitted in November 2009 to include all phases of this project. Phases 2 and 3 are anticipated to be permitted as "corridor" impacts. Previous to this submittal, a design charette was conducted to develop a conceptual vertical and horizontal alignment. Representatives from many environmental agencies, including USCG, USACE, DWQ, CAMA, and NMF took part in the discussions. Based on input from these agencies, the alignment was adjusted to improve minimization and avoidance of impacts to natural resources. Historical features located near the project site have been avoided. No water or wastewater service is included as part of this project. The project permit boundary will be established to achieve the Low Density stormwater permitting option and will have pockets of High Density. Consistent with Low Density stormwater strategy described in requirements set forth in the Session Law 2008-211 Section 2.(b)3b, sheet flow and flow through vegetated conveyances (grassed swales) will be maximized along the project corridor. Generally, the roadway will have a 46 ft depressed median cross section. The roadway will generally have three (3) distinct typical cross sections: Section Proposed Typical Stormwater Strategy Permitting Description Section Strategy Tangent and Depressed median, Utilize shoulder sheet flow and Low Curve Sections open shoulder, grass roadside swales. Occasional median Density swales discharge points will be discharged to preformed scour holes. No other structural BMPs are proposed in these roadway sections. Tangent and Depressed median, Utilize shoulder sheet flow and Low Curve Sections raised median with roadside swales. Occasional median Density curb and gutter and discharge points will be discharged to with open shoulder, grass preformed scour holes. No other Occasional swales structural BMPs are proposed in Pockets of these roadway sections. Collect High stormwater In pipe systems and Density convey to structural BMP prior to discharge Bridge/Culvert Curb and gutter Collect stormwater in pipe systems Pockets of approaches and and convey to structural BMP prior to High other sections discharge Density requiring curb and gutter Gate n/a Utilize sheet flow and swales or Pocket of collect stormwater in pipe systems High and convey to structural BMP prior to Density Stormwater Narrative Page 2 Proposed structural stormwater BMPs will be designed in accordance with the 2007 NC©ENR Stormwater Best Management Practices Manual and will be designed in compliance with requirements set forth in the Session Law 2008-211 Section 2.(b)3b. The total proposed impervious area and placement of structural stormwater BMPs will be determined as the project progresses. To comply with the low density option, built upon area (BUA) will be 24% or less. The stormwater BMPs will be located outside the vegetated buffer for each stream. The new base entry road will pass close to some existing and proposed developments served by appropriately sized best management practices; however, it is strongly desired to treat stormwater from this project independently from other development on the base and with the project corridor. ' The roadway will typically be constructed in fill elevated above existing terrain. Off -site drainage will pass through the roadway via culverts in locations of natural drainage conveyance. Existing streams will be conveyed under the roadway in appropriately sized culverts following typical NCDOT criteria. These culvert crossings will provide a combination of low and high flow conveyances to maintain natural conditions along the jurisdictional corridor passing under the road. The three significant watercourses (;Northeast Creek, Wallace Creek and Bearhead Creek) will be spanned by bridges. Coordination with FEMA is planned to ensure compliance with floodplain regulations. The project site is located in an area that is mostly previously undeveloped land. There are some localized areas of development that the roadway corridor will impact, some of which might be pre-1988 built upon area. An on -site evaluation of soils is currently underway. Results from this evaluation will provide details about infiltration rates, seasonal high water table elevation, and other soil characteristics. This information will be used to assist in the selection and design of appropriate BMPs for the project.

DV MEMORANDUM On USMC Camp Lejeune New Base Entry Road and Gate and Brewster Blvd. Widening Storm Water Scoping Meeting with DENR at Wilmington Regional Office 10:00 —12:00 pm, November 4, 2009 Attendees DENR: Linda Lewis, Christine Nelson, Janet Russell USMC Camp Lejeune: David Towler, Steven Whited, Orathai Bulfer, Pete Wright (NAVFAC/MIDLANT), Craig Hooper (NAVFAC/MIDLANT) MACTEC/RK&K Joint Venture: Jesse Barker, Jeff Meador, Tina Swiezy, Louise Slate Meeting Minutes: Jeff Meador (JM) presented the drainage design for the base entry road (BER) and Brewster Blvd. Drainage on contract A, which runs from Rte 24 to Brewster Blvd and includes the Brewster Blvd. widening, is complete. Drainage design on contract B and C is preliminary. The new entrance gate is part of contract B (FY 12) so the drainage design is still conceptual. Some of the existing roads that are tying in have existing ditches. These are picked up and carried to existing out lets. Much of the new road relies on sheet flow and no ditches are proposed. Linda Lewis (LL) requested that she would like to see plan and profile views on the same sheet with spot elevations clearly shown. These sheets will also show if there is a ditch or no ditch along the road and how ditch drainage is controlled. Supplement these sheets with typical cross section views. At the intersection of Bougainville Drive and the BER a cross pipe takes drainage under the BER then under Bougainville Drive. There is some additional drainage in the median at Bougainville Drive that needs to be picked up due to superelevation of road. JM said that due to elevation and area constraints, he requested guidance from DENR on how to handle median drainage since treatment is difficult. LL said to look at the rest of the BER and then make a decision. (Coming back to this later, it was determined to offset this small impact by using additional inlets in low points and remove pipe to the maximum extent practicable, particularly near the bridges and ramps.) LL said that the portion of existing service road (used as part of the multipurpose trail) located within permit limits must be accounted for when determining low density requirements. Christine Nelson (CN) said to be sure the calculations for each pre -formed scour hole take into account only the active edge where water flows to ensure diffuse flow. Below inset B on the roll plot, look at velocity of cross drainage and control it if necessary before it enters the wetland. (Check pre- vs. post -construction flow velocity.) The BER corridor passes closely behind some new housing in Tarawa Terrace. Pete Wright (PW) asked if there was going to be a berm behind the houses to screen them and control noise. JM said there isn't room for a berm. A noise wall may fit. If inlet capacity in medians is limited, LL prefers double or triple inlet boxes in low points as opposed to additional inlets upslope to capture flow and piping it. The less pipe the better. Show drainage from the stormwater pond on the south side of Northeast Creek so it is clear how it enters the borrow pit. Also show velocity from scour hole to the wetland. MEMORANDUM At the Brewster Blvd. interchange, Brewster is on grade and the BER goes over it. Some of the existing ditches on Brewster may have steeper side slopes than 3:1. When the Brewster is widened though this interchange, flatten the ditch side slopes to 3:1. Water that is piped under the ramp and road discharges to a non -jurisdictional feature. BER drawings for Sections B and C are based on LIDAR. Updates to the drawings will be made when survey is complete and imported into the drawing. The BER from Brewster Blvd to Wallace Creek uses sheet flow off edge of pavement, cross drainage, and median drainage to pre -formed scour holes. It is very straightforward and simple. Any concentrated flow in this section will be limited to the overpass at Stone Street. That drainage will be taken from a pipe to a pre -formed scour hole. The multipurpose trail will cross small streams on culverts rather than bridges. Contract B goes to the Wallace Creek interchange. Wallace Creek commercial development phase 1 is permitted. Phases 2 and 3 aren't permitted yet. Need to coordinate permit boundaries with this development. Road tie in will be part of Wallace Creek development. Preliminary stormwater ponds have been designed for the bridge over Wallace Creek.. JM indicated these ponds may need to use weir overflow rather than a pipe due to elevations and seasonal high water table (SHWT). LL suggested reconfiguring the forebay to maximize travel time in pond. She also suggested the design team could consider a stormwater wetland instead of a pond to take advantage of the elevations and SHWT. If stormwater treatment is needed at interchange at Holcomb Blvd., LL suggested using the inside of the interchange. Brewster Blvd. widening design proposes to: • Keep existing cross drains in place — upsize or maintain as needed. Some joints may need repair • Use existing ditches • Remove some curb and gutter LL asked that existing ditches be regraded to make them 3:1 side slopes if they're steeper than that. An existing well at Charles Street and Brewster Will be replaced with a new well with another well away from the road. The Loop Road and Brewster Blvd can be part of the same permit IF the existing road area removed or reused is equal to the proposed road area. If the proposed road area is greater than existing, treat the ring road as low density and tie it to either the BER permit or the Wounded Warrior permit. CN wanted clarification as to what's happening with the wetland across from the child development center (CDC). As part of the road widening project the sidewalk is going to shift into this wetland (401/404 permit will be required). This wetland drains toward the CDC. MEMORANDUM $I The permit boundaries will be set so that Brewster and the BER do not overlap. Brewster Blvd permit boundary will be set at the back side of the drainage ditch for the length of the project. BER permit boundaries will stop and start on either side of the Brewster permit boundaries. The overall impervious area within the BER permit boundary will be 24% or less. This includes the high density bridge areas. Submit drawings clearly showing permit boundaries as part of the application package. Clearly mark them as high density areas, low density areas, or other. (Brewster falls under'other'.) CN asked that we show permit numbers on the drawings. Janet Russell (JR) can provide this information since permit numbers are assigned based on scoping meeting request. There are no deed restrictions on base. This part of the permit application is not applicable. St:ormwater ponds - Need to add sediment removal elevation on plan. Base staff will sign operation and maintenance (O&M) plans for.structural stormwater BMPs. LL and CN looked at 11x17 drawings. Comments as follows: • Add roadway typical sections • Add existing topo contours to the plan/profile sheets • Show ditch profile on road profile sheet • Turn on high point/low point layer. Spot elevation wanted. • Show pipe inverts. LL would like a pipe summary table added to the plan sheets instead of looking though the calculation package for this information. CN asked how future sections will be handled. A phasing sheet will be developed to overlay the permit boundary drawing showing current and future sections so their limits are clear. A master sheet showing the phases/permit boundaries will be submitted with each permit along with relevant detail sheets. LL indicated that we can allocate future built upon area (BUA) in the corridor to allow for a future road crossing, driveway, or other encroachment. Extra BUA allocations will mean that future impacts to BER corridor can be handled with a plan revision as opposed to a permit modification. At the interchange on NC 24, the boundary of the stormwater permit on base will go to the edge of DOT's right of way. DOT will own the interchange and they will permit all portions of it off base. CN asked about vegetated filters. Jurisdictional streams have a 50 ft. vegetated buffer from top of bank. Northeast Creek has a 75 ft. buffer. Do not submit calculation package in a binder. Clip it together. JR brought up fees for the permit applications. $4000 for the base entry road — covers high and low density areas $2000 for Brewster Boulevard road widening $2000 for the ring road — low density - treated as a major modification Want to have the permit application ready to send to DWQ before Thanksgiving. MACTEC/RK&K will coordinate signatures required from the base through Orathai Bulfer.

Areas of high density and low density are highlighted. a. These should be submitted as two separate design packages that accompany separate stormwater permit applications. b. Discussed how plans should be submitted. i. Christine Nelson (CN) would rather have full size plan sheets than half size sheets. 1. High density sections are to be presented at a scale of 1'=50'; 2. Low density sections may be presented at a smaller scale, as long as they are legible. 3. Fold sheets to make them manageable and fit into files. 4. Only send hard copy plans. 5. The project permit boundary should be shown on all sheets ii. On the high density drawings, show drainage areas to be treated in each BMP. iii. Show jurisdictional features on the drawings. Limit built upon area (BUA) in buffers. 3. Brewster Blvd. schematic drawing was presented to DENR for the first time. a. CN asked if 50 ft buffers will be impacted with BUA anywhere other than at crossings. The answer is no. There is one location where the toe of fill will encroach into the buffer. b. CN asked to have clear legends on plan sheets. 4. Calculations a. Linda Lewis (LL) does not need to see calculations for storm drainage design unless there is a need to show outlet velocities into wetlands are less than 2 feet per second (fps). Methods for calculating velocities should be clear. b. LL and CN may need to see supplemental information used in developing calculations, particularly for any number that is shown in the actual permit application. c. LL said not to use the SCS method for stormwater calculations. Use the simple method presented for sizing BMPs in accordance with the BMP manual. d. CN said to use chapter 3 of BMP manual for calculations 5. Moving forward from here a. TS asked if we needed one more scoping meeting before the submittal on November 2. It was agreed that one more meeting to go over the, design in detail would be helpful prior to November 2. Any items found during that meeting can be addressed, expediting the review process starting on Nov. 2. 6. Ring Road MEMORANDUM of Before the meeting adjourned, a plan view of the ring road around the Child Development Center was presented to DENR by Emily Sylvester. Louise Slate asked if this project could be added as an amendment to the Brewster Blvd widening permit or if it needs a separate permit. LL said that this can be included as part of the Brewster Blvd. permit. 6capC_' For OENR Use ONLY Reviewer: !._�c s�n�l: �~ 1% AG North Carolina Department of Environment and Natural Resources 30 NCDENR Request for Express Permit Review Time: t o Confirm: � FILL-IN all the information below and CHECK the Permit(s) you are requesting for express review.

The project includes the construction of approximately 6.5 mile roadway 4-lane corridor spanning from Bell Fork Road at NC24 to Sneads Ferry Road and includes four major interchanges and three bridges spanning waterways. The project also includes the construction of a new base entry gate. The road will be designed based on NCDOT design standards. Excluding the planned interchange with NC24, the project is planned to be constructed on property owned by the US government on land that is mostly previously undeveloped. The following provides details regarding the property on which the proposed project is planned for construction: Street Address, city, county— New Base Entry Roadway, MCB Camp Lejeune, Onslow County, NC Acres in Tract— to be determined when project boundary is set to allow low density stormwater permitting option Ownership Information from NC Secretary of State Web Site— US Government Property Tax Parcel ID number— US Government Property The project is planned to be phased over three (3) years and be designed and constructed in three (3) phases. The following lists each phase along with the planned construction year in parenthesis: Phase 1— From Bell Fork Rd. at Rt. 24 to Brewster Blvd. (August 2010) Phase 2 — From Stone St. to Sneads Ferry Rd. (March 2011) Phase 3 — From Brewster Blvd to Stone St. and off -base interchange at Rt. 24 (2012). The project site is located in Onslow County, North Carolina and is in the White Oak River Basin. The roadway drains to three main receiving waters: Northeast Creek, Wallace Creek, and Bearhead Creek. The following table lists each stream with its DWQ Classification. Stream Name DWQ Classification DWQ Index Northeast Creek SC NSW 19-16-(0.5) Wallace Creek SB NSW 19-20 Bearhead Creek SB NSW 19-20-1 This project has been included in Grow the Force initiative planning process including a total of approximately 75 projects planned at various site throughout North Carolina including Camp Lejeune, USMC Air Station New River, and MCAS Cherry Point. A Draft Environmental Impact Statement (DEIS) has been prepared for these identified projects. The DEIS is planned to be released for public comment in July 2009. A Record of Decision (ROD) is anticipated in January 2010. The USACE and DWQ have reviewed wetland and stream delineations shown on the plans and has concurred with the delineation. Coastal wetlands have been delineated by the project team and DCM verified these determinations and the Section 10 waters within the project corridor. Stream and wetland impacts will be permitted for the entire project through the Army Corps of Engineers (ACE). A Stormwater Narrative E E I V j: Page 1 V AUG 2 6 2009 00n , DWQ 401/404 application is planned to be submitted in November 2009 to include all phases of this project. Phases 2 and 3 are anticipated to be permitted as "corridor" impacts. Previous to this submittal, a design charette was conducted to develop a conceptual vertical and horizontal alignment. Representatives from many environmental agencies, including USCG, USACE, DWCt CAMA, and NMF took part in the discussions. Based on input from these agencies, the alignment. was adjusted to improve minimization and avoidance of impacts to natural resources. Historical features located near the project site have been avoided. No water or wastewater service is included as part of this project. The project permit boundary will be established to achieve the Low Density stormwater permitting option and will have pockets of High Density. Consistent with Low Density stormwater strategy described in requirements set forth in the Session Law 2008-211 Section 2.(b)3b, sheet flow and flow through vegetated conveyances (grassed swales) will be maximized along the project corridor. Generally, the roadway will have a 46 ft depressed median cross section. The roadway will generally have three (3) distinct typical cross sections: Section Proposed Typical Stormwater Strategy Permitting Description Section Strategy Tangent and Depressed median, Utilize shoulder sheet flow and Low Curve Sections open shoulder, grass roadside swales. Occasional median Density swales discharge points will be discharged to preformed scour holes. No other structural BMPs are proposed in these roadway sections. Tangent and Depressed median, Utilize shoulder sheet flow and Low Curve Sections raised median with roadside swales. Occasional median Density curb and gutter and discharge points will be discharged to with open shoulder, grass preformed scour holes. No other Occasional swales structural BMPs are proposed in Pockets of these roadway sections. Collect High stormwater in pipe systems and Density convey to structural BMP prior to discharge Bridge/Culvert Curb and gutter Collect stormwater in pipe systems Pockets of approaches and and convey to structural BMP prior to High other sections discharge Density requiring curb and gutter Gate n/a Utilize sheet flow and swales or Pocket of collect stormwater in pipe systems High and convey to structural BMP prior to Density discharge Proposed structural stormwater BMPs will be designed in accordance with the 2007 NCDENR Stormwater Best Management Practices Manual and will be designed in compliance with requirements set forth in the Session Law 2008-211 Section 2.(b)3b. The total proposed impervious area and Stormwater Narrative Page 2 placement of structural stormwater BMPs will be determined as the project progresses. To comply with the low density option, built upon area (BUA) will be 24% or less. The stormwater BMPs will be located outside the vegetated buffer for each stream. The new base entry road will pass close to some existing and proposed developments served by appropriately sized nest management practices; however, it is strongly desired to treat stormwater from this project independently from other development on the base and with the project corridor. The roadway will typically be constructed in fill elevated above existing terrain. Off -site drainage will pass through the roadway via culverts in locations of natural drainage conveyance. Existing streams will be conveyed under the roadway in appropriately sized culverts following typical NCDOT criteria. These culvert crossings will provide a combination of low and high flow conveyances to maintain natural conditions along the jurisdictional corridor passing under the road. The three significant watercourses (!Northeast Creek, Wallace Creek and Bearhead Creek) will be spanned by bridges. Coordination with FEMA is planned to ensure compliance with floodplain regulations. The project site is located in an area that is mostly previously undeveloped land. There are some localized areas of development that the roadway corridor will impact, some of which might be pre-1988 built upon area. An on -site evaluation of soils is currently underway. Results from this evaluation will provide details about infiltration rates, seasonal high water table elevation, and other soil characteristics. This information will be used to assist in the selection and design of appropriate BMPs for the project. nE C E B V ED UU AUG Z 6 2009 PROD # _ DWG?

Introductions were made around the room 2. Focusing on a portion of phase one road section, Tina Swiezy presented the concepts for addressing stormwater runoff from the new base access road to get buy in from DENR before applying these concepts to the entire 6.5-mile road. 3. Concepts are based on low density with pockets of high density development. a. Tangent sections — sheet flow to the toe of slope; occasional pipe to drain median b. Curve sections— sheet flow where possible; swales and piping where necessary c. Bridges = Drain to a wet pond sized to treat the first 1-5-inches of runoff and store runoff from 10-year storm event before bypassing flow through spillway 4. The following is a recap of discussions and issues considered/discussed: o Christine Nelson (CN) stated that below a discharge pipe into a preformed scour hole, only the downstream side of a level spreader can be counted. o A discussion on how best to drop treated runoff from a swale into the creek located south of Tarawa Terrace housing. ■ Pipe treated runoff from the swale into the culvert at channel level (least invasive to natural system — accomplishes grade drop without erosion — preferred by design team) • Build a level spreader and turn runoff into the wetland (issue — level spreader would be at the top of the bluff so getting the runoff to stream level at a non - erosive velocity would be a challenge) ■ Clear existing vegetation and grade a wide, flat, grassed Swale (largest impact on wetland system) ■ Georgette Scott (GS) asked the design team to provide a sketch of the alternatives along with the amount of water, velocities, and slopes to help them evaluate the best alternative o Linda Lewis (LL) asked if there would be access to this entry road from other developments on base. Emily Sylvester (ES) said that this will be a controlled access road in order to maintain the speed limit. LL stated that it would be helpful to make the project boundary slightly larger than necessary in order to accommodate future development. o CN asked if the design team has looked at neighboring stormwater permits. 0 Not yet. David Towler (DT) and ES of MCBCL can help provide this information. MEMORANDUM Al o Tina Swiezy (TS) asked if a borrow pit can be used as a stormwater feature. ■ LL said it could be used if it were designed as a wet pond. Need to design a drawdown feature for the design storage volume. ■ Keep depth 20 feet or less. ■ CN suggested building a constructed wetland as an educational feature at the Boy Scout camp. ■ TS said it would be possible to build a wet pond to treat bridge runoff that discharges into the borrow pit. ■ LL suggested designing a forebay in the borrow pit sized to treat bridge runoff with a drawdown structure and outlet that discharges directly into the pit. o DENR will respond to questions related to areas of concern during stormwater design development. Develop an alternatives evaluation sketch and write up and email to LL. o Drawings need to be at a legible scale; sensible for what is being shown. o DENR would like to see drawings of each type of proposed cross section. o Need to evaluate seasonal high water table (SWWT). o Design team would like to submit the stormwater application in early November, The design team would like to meet with DENR —4 weeks prior to this submittal to do a final scoping meeting/completeness review. o Design team needs to develop a conceptual design for Brewster Boulevard widening. Include right of way as part of project boundary — target low density ■ Treat this as a separate project — send separate application and fee ■ Minimize impacts ■ Direct runoff away from surface water ■ Employ BMPs to the maximum extent practicable 2 4000 MUTI•PURPOSE PATH 14' MyTI•PURPD,JF_ 3D' _ t0' 12' __ 12' SMASSIE N 12' 12' 10' 18 6 10 PATH tYMYRH 6' IT 1P fi {�.
