A copy of the lease agreement that outlines Wilmington NC VA 2011 LLC, responsibilities for this stormwater system, must be kept with the permit and maintenance activity records. Please pay special attention to the requirements and procedures for Operation and Maintenance, permit transfer and permit renewal in this permit. Failure to establish an adequate system for operation and maintenance of the stormwater management system, to follow the permit transfer process or to renew the permit, will result in future compliance problems. Please be aware that it is the responsibility of the permit holder, Wilmington NC VA 2011 LLC, to notify DWQ of any changes in ownership via the submittal of the name/ownership change form. However, please be reminded that if the lease agreement or contract between Wilmington NC VA 2011 LLC and the New Hanover County Airport Authority is dissolved, cancelled or in default, and DWQ is not notified by Wilmington NC VA 2011 LLC to transfer the permit, then the responsibility for permit compliance reverts back to the property owner. As the property owner, New Hanover County Airport Authority must notify DWQ immediately of the permit ownership change and submit a completed and signed Name/Ownership Change form to DWQ within 30 days. Otherwise the New Hanover County Airport Authority will be operating a stormwater treatment facility without a valid permit.

The project is located approximately 0.20 miles east from the intersection of Airport Blvd. and 23rd Street along Airport Blvd. The site currently drains to an unnamed tributary Smith Creek (C; Sw) [18-74-63] within the Cape Fear River Basin and according to the NRCS Soil Survey of New Hanover County the soil at the site consists of Pantego Loam (Pn). The site currently consists of a combination of woods and grassed areas with the old Gardner Drive roadbed traversing the middle of the site. The site is bound by the realigned Gardner Drive to the east, Airport Boulevard to the south, an existing building and wooded areas to the north, and an existing ditch and jurisdictional wetlands approved by the Army Corps of Engineers to the west. An existing ditch currently runs through the middle of the property and nearly half of the site drains toward this feature. On the northwest portion of the property, the site drains toward the existing wetland pocket and a ditch to the west of the property. The elevation ranges from 27 feet mean seal level (FMSL) near the middle of the property to 20 FMSL at the outfall of the culvert under Gardner Drive. Based on the information above, the site will be broken into two drainage basins. This approach will best mimic the existing drainage patterns on site. The wet detention ponds were also located to try to minimize the amount of trees affected while still meeting the requirements of the various agencies stated above. The wet detention ponds will treat and control a majority of the site and building runoff by conveying the stormwater through a stormsewer piping system. The runoff will be controlled in the ponds through the use of outlet structures for primary control and spillways for greater rainfall events. MAINTENANCE Contractors shall be responsible for periodic inspection and maintenance of all indicated erosion control devices in accordance with the plans and specifications. In addition, inspection and any necessary maintenance will be required immediately following any significant storm event. Any erosion control measure that fails to function as intended shall be repaired immediately. Upon completion of construction and the establishment of stabilized ground cover, the property owner shall be responsible for any on going site maintenance.

I've attached a marked up copy of the average depth calculations that were submitted. The problem appears to be a discrepancy in the "Depth" used in the calculation. Both of the depths I calculate from the elevations reported on the revised supplements, are 0.5 feet less than what you are using. The "depth" is the difference between the bottom of shelf elevation and the top of the sediment elevation. Interestingly enough, the "depth" reported on both supplements is correct. For Pond #2, the bottom of shelf area and the bottom of pond area you use for the average depth doesn't match up to the areas in the stage-storage calculations (13,057 (avg) and 2,682, respectively.) Where does the 12,200 and the 2,784 come from? Even though this results in a smaller average depth and a larger minimum required surface area, there is plenty of surface area provided to meet the new minimum area. You'll need to revise the "average depth calculated" and the "average depth used in SA/DK on the supplement form for Pond #1 and for Pond #2. In addition, for Pond #2, the "Bottom of shelf area" needs to change. You've already got 2682 as the bottom of pond area on the supplement, although you didn't use that number in the average depth calculation.

Please find your comments below with our response provided in bold. 1.) Average Depth Calculations • We have updated the average depth calculations to reflect your comments. In the calculations,we have added the forebay volumes as requested. Please note because this project had greater surface area than required based SA/DA ratio we added such calculations, but on future submittals we may revisit this based on location of shelf in pond 2.) Permanent Pool Volume Calculations • These have been updated to be consistent 3.) Grading Plan • As stated in previous emails, PG is top of pavement and 6" can be added to back of curb • We have added the proposed contours to the resubmitted set 4.) Permanent Pool Dimensions • The dimensions have been added to the plan 5.) Shelf Planting Calculation • This has been calculated and added to the resubmitted set 6.)

Figure 10-2b in the BMP Manual provides the calculation of the average depth when Option #2 is chosen on the supplement form. Each of the parameters to input into the equation is explained in that figure. Each surface area, except for the bottom of the pond, includes the forebay area. The bottom of the pond area excludes the forebay only because in most cases, the forebay is shallower than the main pond. In cases where the bottom elevation of the forebay is the same as the bottom elevation of the main pond, I would include the forebay bottom area as part of the total bottom surface area that you use in the calculation. 2. Thanks. 3. So we need to add 6"to the PG elevation in order to obtain the top of curb elevation? 4. The dimensions help us in determining if the drawings accurately depict sufficient surface area and help the contractor to stake the pond. Print stretch is a problem (maybe an old problem with the old blueprints), but we do not want to rely on a scale for this very important aspect of the plan. Scaling can go both ways — it can either be in your favor or not. We tend to scale very conservatively, so in the absence of specific dimensions, it's possible that the area we calculate will be less than what you might calculate. Rather than take a chance on that, it's best to just add sufficient dimensions to remove all doubt about what it's supposed to be. 5. The minimum Plant and Landscape requirements for wet ponds can be found in Section 10.3.7 of the BMP Manual. 6. I'm confused about the seeding because on Sheet C-6.1, the pond section detail in the lower left corner indicates that the side slopes above permanent pool will be sodded. If the slopes will be seeded, please correct this detail. If the slopes will be sodded, please spec the sod type on the detail., Hope that answers your questions. Let me know if you need anything else. Linda Lewis NC Division of Water Quality 127 Cardinal Drive Ext.

We believe such clarification will make us easier for both parties to clear things up. i For comment#1 (Average Depth Calculation), I am enclosing an updated spreadsheet on the average depth with the inclusion of the forebay in'our calculations. Please let us know if this suffices, earlier Chris as in the past, calculated the depth for the main pond only. For comment#2 (Permanent pool volume), we have updated the supplements and will submit upon approval of other comments For comment 3, (Grading Plan), the PG on the plans represents the top of pavement, in addition we have added the contours. For comment 4, (Permanent Pool Dimensions), as in the past (past permitted projects) we have not added such dimensions because the plans are shown to scale, and the contractor will construct as plan and we have to certify the ponds at the end of the project For comment 5, Not being hard to get along with, but can you show me in the manual or statue law where the number of planting is shown as such, I am asking for such because I have looked through the various literature and the owner will ask where such information is located as they start construction. Your help is appreciated on this front. For comment 6, the owner plans to seed the ponds (see Sheet C-1.0) Thanks for your patience on this and we are trying our best to answer the comments in the most efficient manner.

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. Average depth calculations - The areas used for bottom of shelf, bottom of pond and permanent pool do not match up to the areas for the corresponding elevations in the Stage-Storage calculations. For example, the average depth calculation for Pond #1 uses a permanent pool area of 26,368 sf, but the supplement and the pond calculations both say that the permanent pool area provided is 35,854 sf. 2. Permanent pool volume calculations - The accumulated volume from the stage- storage table at the permanent pool elevation does not match the volume reported on the supplement for either pond. 3. Grading Plan a. What does "PG" on the grading plan stand for? It is not listed in the plan legend. The plan notes indicate that the spot elevations are for the proposed edge of pavement, but curbing is proposed as well, so is the curbing considered the "edge of pavement'? Please identify the spot elevation as either the top of the pavement or the top of the curb. b. Provide a complete grading plan where the proposed contours are connected back to the existing contour and the pond contours. There is a lot of fill proposed for this site. 4. Permanent pool dimensions —The dimension detail should include the straight lines and arc lengths of the entire permanent pool contour line, not just two dimensions cutting across the widest and longest parts of the pond, stopping and starting at unidentified points. 5. Shelf Planting Calculation — Provide a calculation on the plans of the minimum number of plants to be planted on the shelf area, based on 50 plants per 200 sf of shelf area. A list of suitable plant types was provided, but the minimum number of plantings that are required was not.
