Included below are your comments, which have been included for ease of reference and our responses to the comments. 1. Please seal the revised bio-retention calculations.

Can you en ighten me this information is needed in order to determine if the required ratio of 1 free for every 2- 3 shrubs has been provided. The attached Landscape plan has been revised, additional information was added to the plant list table to indcate that the plant is a tree or shrub. The correct number of plantings and there location was also corrected on this plan. 3. The area of the basin has increased dramofically over what was previously submitted, how ever, the size of the basin does not appear to have changed on the plans at all. It is not op prop6ote to include the swale that transports the runoff to the basin as part of the basin are a. They serve different functions. Additionally; bio-retention basins must be a minimum of 15wide. ff you were to widen the swale and provide plantings in the swale as well, then i c ould give you area and volume credit for the swale, since it would be part of the basin. If y ou do this. the landscape plan w171 need to be revised. The increase in the basin area was a result of added the swale's area to the BRA. I have revised the calculation in accordance with our May 5, 2006 meeting: • The bio-retention area surface area only uses the larger storage area that has a minimum of 15' of width. • The storage volume uses both the bio-retention area and the Swale. The calculations show the two items separately and the totaled area. • The draw down calculations use only the bio-retention area • Page 2 May 6, 2006 f I trust our comments answer your questions regarding this project.

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. Two of the inverts listed on the "Outlet Structure #2" detail are 98 and 94.35, which are much higher than the other inverts and elevations on the plans. 2. Please show Mr. Saunder's property line on the "Drainage Swale Detail". 3. Please note next to "Swale A" that it's detail is called "Drainage Swale Detail". 4. Please provide a specific, detailed planting plan. You need to actually show the type of plants, where the plants will be planted within the basin, and how many will be planted in that particular location, similar to the type of plan that a professional landscaper would do. There are certain requirements regarding the spacing and locations of the plants, more particularly described in Table 4.6 and in Section 4.13 of the BMP manual. 5.

Included below are responses to the comments of your November 5, 2005 letter. Your comments have been included for ease of reference. 1. The design calculations only address surface area. Please provide the 1.5" volume calculations and the calculations for the minimum number of plants. Please demonstrate that the basin provides sufficient volume to accommodate 1.5" of runoff, and that there are a minimum of 1000 trees and shrubs per acre of bioretention basin area at a ratio of 3 shrubs for every tree. The calculations have been revised, the surface area, 1.5" volume and minimum plantings calculation are included in the report and the plans have been revised to provide the necessary areas, volumes and plantings. 2. Please provide a signed Operation and Maintenance Plan for the bioretention basin, blank copy attached. A signed Operation and Maintenance Plan is included with this submittal. 3. Please provide calculations for how you determined the Rational "C" coefficient. The Calculations have been revised to include the weighted rational coefficient calculations. 4. Please remove the dark shading within the parking lot on the plans or choose a much hghtershade of gray. tt is obscuring the necessary plan information and is difficult to read. The plans have been revised with lighter shading. 5. Please label the contour&nes in the bioretention basin with their respective elevations on the plan view and label the bottom and ponding elevations on the section view. The plans have been revised, the bio-retention's contour fines have been labeled and the section now indicates that the bottom elevation is 26.0. _� T - � 4 4 .. _ ,� �. � � �� � ; i e, -� 0 Page 2 November 21, 2005 6. Please redesign the bioretenlion outlet structure. As currenfly designed, most runoff from the project will drain into the swale, which wig drain directly into the open grate of the bypass structure. Please lower the invert of the swate and provide a wall or a berm between the swale and the bypass structure to prevent shorkircuiting. The elevation around the outlet structure has been lowered to the b io-retention bottom elevation, which provides the overflow structure 1 foot of free board before overflawing; additionally the swale has been moved slightly to insure that the inflow is not directly to the overflow structure. 7. How are you planning to deal with the runoff from the George Saunders property? It appears that this property is higher, and reties on the existing pond for its drainage relief. Under civil law, you may not black his drainage from reaching this historic drainage outlet. You wig need to either account for the runoff from this offsite drainage area at the fug build -out potential or provide a means for the runoff from Mr. Saunders' property to get to the e*iing pond, if the pond is the historic drainage outlet for his property. Runoff from George Saunders property will be intercepted with a berm on the up hM side of the project's swale. The berm vd transport the runoff to an inlet and then to the existing pond. 8. Please show the nearest intersection of two majorroods on the vicinity map. A major mad is any 1, 2, or 3 digit NC, US or interstate highway.

Please lower the invert of the swale and provide a wall or a berm between the swale and the bypass structure to prevent short-circuiting. ® How are you planning to deal with the runoff from the George Saunders property? It appears that this property is higher, and relies on the existing pond for its drainage relief. Under civil law, you may not block his drainage from reaching this historic drainage outlet.
