If these areas are not flagged, the Soils Scientist reserves the right to decline to do the investigation. If the proposed infiltration system will be located in an area of existing pavement and there is no open area nearby, equipment capable of breaking through the impervious layer must be provided. The soils investigation does not take the place of a soils report prepared by an appropriate professional. The Soils Scientist will only verify the soil conditions that are reported in the Soils Report, and make a determination as to the suitability of the site to meet the infiltration design requirements under NCAC 2H.1000, and assumes no liability should the system fail.

The new Operations Facility will be a one-story brick on slab structure. Upon completion of and occupancy of the new EOD Operations Facility, the existing EOD Operation Building will be demolished. New COD Site Description The site for the new EOD Facility is located on the north side of McHugh Boulevard approximately 1,000 feet west of the intersection with Sneads Ferry Road in the French Creek area of Camp Lejeune. Building FC51, an Electronics and Communications Maintenance facility is located immediately to the east of the EOD site, facing Sneads Ferry Road. The French Creek borrow pit is located south of the EOD site, on the south side of McHugh Boulevard. Existing Site Drainage The project site is currently wooded primarily with pine trees and some oak trees, ranging in size from 6-inches to 24-inches, and undergrowth of small pine trees. There is no existing storm drainage system and the land slopes gently to a low area northwest of the project site. Drainage for the area is primarily through infiltration, as the soil is very sandy and pervious and no defined drainage ways or outfalls are present in the area. The soil at the site is Baymeade fine sand (BaB) according to USDA Soil Survey of Onslow County. This a well -drained sandy soil characterized by rapid infiltration and slow runoff. The hydrologic soil group is group "A". Soil boring performed at the site indicated the soil has a Unified Soil Classification System (USCS) classification of SP, which is a poorly graded sand and gravelly sand with little or no fines. Groundwater will likely be encountered in excavations extending two meters or more below the surface. Due to the high sand content of the subsoil, the infiltration/permeability capability of these soils is high. Post Development Drainage Runoff from the new development will be controlled through overland flow over lawn areas, grass lined swales and bioretention areas to treat the first 1-inch of runoff from the developed areas. The runoff will be directed to new vegetated swales and allowed to flow into the adjacent woods, similar to existing conditions. Piping is only provided where necessary for road and sidewalk crossings. Existing EOD Facility Site The existing EOD Facility, Building 1308 is located on the southwest side of Cedar Road, between East Road and Hammond Road. Southwest of building 1308 are buildings 1311 and 1312, which are both part of the EOD facility compound. The compound is fenced with bituminous concrete paving in between the three buildings. A bituminous concrete parking area is located in front of building 1308 along Cedar road. Upon completion of construction of the new EOD facility, building 1308 will be demolished. Building 1311 and 1312 will remain. After building 1308 is demolished, a new bituminous concrete 33-vehicle parking lot will be constructed. The project site is flat, covered by approximately 80% impervious area and 20% grassed area with grass lined drainage ditches surrounding the site along the roadways. The parking lot is configured to occupy the footprint of the demolished building, with access to Cedar road. Total impervious area will be reduced with the layout provided thus no additional stormwater controls will be required. The fence will be extended from the north side of the parking lot to the south side, to secure the paved areas adjacent to buildings 1311 and 1312. Prepared by: David C.

The new Operations Facility will be a one-story brick on slab structure. Upon completion of and occupancy of the new EOD Operations Facility, the existing COD Operation Building will be demolished. New EOD Site Description The site for the new EOD Facility is located on the north side of McHugh Boulevard approximately 1,000 feet west of the intersection with Sneads Ferry Road in the French Creek area of Camp Lejeune. Building FC51, an Electronics and Communications Maintenance facility is located immediately to the east of the EOD site, facing Sneads Ferry Road. The French Creek borrow pit is located south of the EOD site, on the south side of McHugh Boulevard. Existing Site Drainage The project site is currently wooded primarily with pine trees and some oak trees, ranging in size from 6-inches to 24-inches, and undergrowth of small pine trees. There is no existing storm drainage system and the land slopes gently to a low area northwest of the project site. Drainage for the area is primarily through infiltration, as the soil is very sandy and pervious and no defined drainage ways or outfalls are present in the area. The soil at the site is Baymeade fine sand (Bala) according to USDA Soil Survey of Onslow County. This a well -drained sandy soil characterized by rapid infiltration and slow runoff. The hydrologic soil group is group "A". Soil boring performed at the site indicated the soil has a Unified Soil Classification System (USCS) classification of SP, which is a poorly graded sand and gravelly sand with little or no fines. Groundwater will likely be encountered in excavations extending three meters or more below the surface. Due to the high sand content of the subsoil, the infiltration/permeability capability of these soils is high. Post Development Drainage Runoff from the new development will be controlled through overland flow over lawn areas, bioretention areas for parking lot runoff, and dry wells for roof runoff. The runoff will be directed to new vegetated swales and allowed to flow into the adjacent woods, similar to existing conditions. Piping is only provided where necessary for road and sidewalk crossings. Existing EOD Facility Site The existing COD Facility, Building 1308 is located on the southwest side of Cedar Road, between East Road and Hammond Road. Southwest of building 1308 are buildings 1311 and 1312, which are both part of the EOD facility compound. The compound is fenced with bituminous concrete paving in between the three buildings. A bituminous concrete parking area is located in front of building 1308 along Cedar road. Upon completion of construction of the new EOD facility, building 1308 will be demolished. Building 1311 and 1312 will remain. After building 1308 is demolished, a new bituminous concrete 33-vehicle parking lot will be constructed. The project site is flat, covered by approximately 80% impervious area and 20% grassed area with grass lined drainage ditches surrounding the site along the roadways. The parking lot is configured to occupy the footprint of the demolished building, with access to Cedar road. Total i us no a stQLQEaLcr control - lred: The fence will be extended from the north side of the parking lot to the south side, to secure the paved areas adjacent to buildings 1311 and 1312.

Soil textures with minimum infiltration rates less than 0.52 inches per hour are not suitable for usage of infiltration practices. These include soils that have a 30 percent clay content, making these soils susceptible to frost heaving and structurally. unstable, in addition to having a poor capacity to percolate runoff. Soil textures that are recommended for infiltration systems include those soils with infiltration rates of 0.52 inches per hour or greater, which include loam, sandy loam, loamy sand, and sand.

The following is our response to your comments. The infiltration basin supplements for the bioretention basins have been removed. The required design information has been included in the calculations. 2. A note indicating that no wetlands are present on the site has been added to sheet C- 1 02 R. 3. A revised drainage area map is attached. 4. The application form has been revised for each drainage area. The contour elevations that apply to the dimensions of the bioretention basins have been added. 6. The bioretention basin ponded water depths have been changed to 12-inches (300mm). The depths of the filter beds are 2.5 feet (762mm). Page 2 SWS 050830 7. The basins have been redesigned to provide sufficient surface area and volume to meet the requirements of the BMP Manual. 8. The ratio of trees to shrubs has been revised to have 1 tree for every 3 shrubs, and to have a minimum number of plants of 1,000 stems per acre of bioretention area. 9. Elevations of the bottom elevation of the sand layer and the top elevation of the ponded water have been added to the bioretention basin detail. 10. A bypass swale has been added to basin B-2. The invert of the swales have been set so that once the biorention basin has reached it's maximum ponded depth, excess runoff will bypass the basins. 11. Vincent Lewis visited the site on November 7, 2005. He determined that the infiltration trench locations would not have adequate clearance from seasonal high ground water at the locations as designed. Due to this and and size requirements, the infiltration trenches have been eliminated. Roof drainage now will flow overland to grass lined swales and discharge into the bioretention basins. 12. As discussed above, the infiltration trenches have been eliminated. 13. Runoff from the off -site built upon area (a portion of McHugh Boulevard) has been routed around the proposed system. 14. All built upon area is included in the drainage area of the proposed system. Upon your review of the enclosed revised documents, please let me know if you need any additional information. Your prompt attention to this submittal would be greatly appreciated. I can be reached at (757) 322-4292, or e-mail david.c.�acksonl u,nay..mil. Sincerely, David C.

The concentration of built -upon area within a relatively small boundary and the way the site is graded are the larger factors which make this a high density project. In order to meet low density, the base would need to designate a sufficiently large project area, keeping in mind that the designated area cannot be developed in the future without modifying the permit. Additionally, the site would need to be graded such that runoff could sheet flow off of the paved areas across and through the open areas of the designated project area, through a minimum 30, wide undisturbed vegetated buffer. There should be no collection, and no point source discharges off of the pavement i.e., no low spots. Part of the problem with low density on the Base is that I don't believe anyone at Camp Lejeune is keeping track of the project area limits that have been previously delineated and used on other low density projects that have been permitted on the base since 1988. In order to avoid using the same area twice, for two different low density projects, the Base was charged with the responsibility of tracking the project limits. Linda Jackson, David C CIV NAVFAC Lant wrote: Linda, I am having trouble making the infiltration systems work due to size and depth. I am also looking at other options, such as wet detention, but I am concerned about concentrated flow from this site which has no defined outfall. When developing the plan, I calculated that the built upon area is approximately 29% of the total site area. The main reason for going not applying for low density was due to the curbing and to try to incorporate LID principles into the design. If I eliminated the curbing and eliminated other areas of concentrated flow, I think this would qualify for a low density development. Please let me know what you think. Thanks for your help, and have a happy thanksgiving. David C.

My calculation of the volume of runoff generated by the roof is significantly less than what you are quoting. For DW-1, I get 575 cubic feet and for DW-2, I get 647 cubic feet. So, the trenches you design must be capable of storing volumes of 575 cubic feet and 647 cubic feet, respectively, in the pore spaces and piping of the proposed trenches. Based on my spreadsheet calcualtions, DW-1 could be 47' long by 10, wide by 3' high and DW-2 could be 53' long by 10' wide by 3' high and provide the minimum volumes in the pore spaces and piping. I don't think it's necessary to increase the trench width to 151, unless you just wanted to over -design. I looked up the permit for the Physical Fitness Center that was issued in 2002. That was a redevelopment site, where we have more flexibility in permitting projects that can't quite meet all the design requirements for practical reasons. Besides that, NCAC 2H.1008(c)(1) states that the storage volume of the system shall be calculated to provide for the most conservative protection.... and allows other methods to be used only if they provide equivalent protection. Linda Jackson, David C CIV NAVFAC Lant wrote: Linda, Thanks for the prompt response. I take from your e-mail that the trench volume needs to be able to hold the entire 1" rainfall volume. To accomplish this, I have calculated that DW-1 will need a volume of 2,034 cf, L=46', W=15', depth=3', and DW-2 would be 2,332 cf, L=52', W=15', depth=31(more or less). The method I used to calculate the original volume was the same as was used for dry wells at the Physical Fitness Center at Courthouse Bay, where the formula for "At" was used to determine required volume, allowing for infiltration during the storm event. I think I have room,in the area for the larger volume, but it will be tight. Please confirm that trench needs to hold the entire 1" volume. Also, I have set up to meet Vincent on -site to look at the 2 trench locations on Monday Nov 7, 2005.

I calculated the storage volume in each trench, assuming no infiltration during the storm (worst case most conservative scenario) by multiplying the length, width and height of the trench, subtracting out the volume of the piping, multiplying the leftover by 0.4, then adding back the pipe volume, to arrive at the total storage volume available in that trench.

Readal: The Wilmington Regional Office received a Stormwater Management Permit Application for the EOD Operations Facility on August 25, 2005. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. Please delete the infiltration basin supplements from the application. Bioretention basin design information should not be reported on an infiltration basin supplement. This will only confuse the application. Please show the required design information for the 2 proposed bioretention basins in the calculations. 2. Please either delineate all wetlands on site, disturbed or undisturbed, or note on the plans that none exist. 3. Please delineate (highlight) the drainage area to each bioretention area, and to each underground trench area. There should be a total of 4 separate drainage areas shown. 4. Please complete a separate column on the application, one for each proposed system. There should be a total of 4 completed columns in Section 111.6 of the application. 5. Please label the contour elevation that applies to the dimensions provided for the bioretention basins. 6. Per the newest BMP Manual, the maximum ponded water depth allowed in a bioretention basin is 12". The current version of the BMP Manual allows for only a 6" ponded depth. The calculations indicate that the volume provided is based on a ponded depth of 3 feet. At this depth, none of the vegetation can survive. Please either reduce the ponded water depth to 12", or redesign the Bioretention basins to wet detention ponds. 7. Neither of the proposed bio-retention basins provides sufficient surface area, and Basin B-2 does not provide sufficient volume to meet the minimum desig n requirements as outlined in the BMP Manual.

The minimum number of plants is 1000 stems per acre of bio-retention basin area. For B-1, the total is 75 stems and for B-2 it is 40 stems. The proposed design provides a ratio of 1 tree for every 8 shrubs. Please either reduce the number of shrubs or increase the number of trees to obtain the desired ratio. 9. Please provide more elevation details on the bio-retention basin detail, like the bottom elevation of the sand layer, and the top elevation of the ponded water. 10. Bio-retention is designed to be an offline system, similar to infiltration. Please explain how the runoff in excess of 1" is bypassed prior to entering the basin. Having an outlet for the runoff that is already in the basin does not meet the bypass requirements. 11. Has our Regional Soil Scientist, Vincent Lewis, been to the site to verify the soils information for the underground trenches? If not, please complete and submit the enclosed form to schedule an appointment. 12. Neither of the trenches provides sufficient volume to meet the 1" design storm requirements. The calculated storage volumes provided in the trenches do not appear to account for the fact that the stone is taking up 60% of the available space. 13. Please delineate the 11,040 square feet of offsite-built-upon area. This built -upon area does not appear to be included in any of the design calculations: Unless this offsite runoff can be routed around the proposed system, it must be included in the built -upon area of the proposed system(s) that it will drain to. 14. There appears to be a little over 3,000 square feet of built -upon area that is not being treated. All proposed built -upon area must be included within the drainage area of a proposed system. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to November 25, 2005, 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 or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from the receipt of a completed application to issue the permit. 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.
