See attached plan review tracking status from the City website. We have watershed protection-storm water approval, storm water conveyance approval, and soil erosion approval. We do not overall approval of the project yet because of an easement release. We have to appear before planning board to release a portion of the water quality conservation easement. Prior to project completion, we will dedicate new water quality conservation easement to replace that portion we asked release of. The planning board will seek input from Virginia and her department regarding this easement release. Based on my discussion with Virginia, she is in favor of the release. I am also attached the latest PCN (forwarded to USACOE) and owner authorization. I believe you have copies of the USACOE permit, City buffer certification, and the no practical alternative narrative. Please let me know if you would like hard copies or if you have any questions. Thanks, Chuck Charles J.

Greensboro Charter Academy Dear Mr. Christy: In accordance with the Jordan Water Supply Nutrient Strategy: Protection of Existing Riparian Buffers., any applicant that intends to disturb Zone 1 on September 12, 2013 stating that the stream buffer disturbances in Zone 1 & Zone 2 were necessary for the installation of a Driveway Crossing. The City of Greensboro determined that the permanent impact of 7,700 sf in Zone 1 and 6,624 sf in Zone 2 of the Jordan Water Supply Watershed stream buffer was necessary to install the driveway crossing including permanent and temporary disturbance. The temporary impact of Zone 1 is 5,422 sf (130 lf) and permanent impact 2,278 sf (36 lf). The temporary impact of Zone 2 is 4,926 sf (22 lf) and permanent impact 1,698 sf (0 lf). All surfaces must be restored with grassed vegetation as soon as the work is completed. Finally, the applicant should secure any other required federal, state, and local certifications before the project proceeds. This approval is valid only for the purpose and design that was described in the application. If any modifications are made to the project a written notification describing the changes, must be submitted to the City of Greensboro Water Resources Department, Engineering Division (Stormwater Engineering Section). If the property is sold, the new owner must be given a copy of the certification and approval letter and is thereby responsible for complying with all conditions. This letter completes the review of The City of Greensboro, Water Resources Department, Engineering Division (Stormwater Engineering Section) under the Determination of No Practical Alternative.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Crossing location was selected based on stream bank height, previous buffer & stream disturbance, and location of buffers. Alternate locations were analyzed to determine location of minimal impacts. Fill slopes were increased from 3:1 to 2.5:1 to minimize fill footprint. The proposed crossing location is the same general area as the previous buffer impact during construction of the dam, reducing impacts to other previously undisturbed buffer and stream on the site. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Existing BMP will be drained prior to construction, eliminating water flow in the downstream channel. Construction during weather forecast of 'no precipitation'. Spillway culvert will be constructed adjacent to existing stream. Embankment will be constructed in phases, restored and protected with silt fence during each phase. Buffer will be protected with silt fence and tree protection fence. storm water will be diverted to temp sediment basin that discharges to existing BMP. Side yard buffer will be restored with vegetation. 2. Compensatory iti ation for Impacts to Waters of the U.S. or Waters of the State 2a.

Reference Note #5 of ‘General Notes’ on Sheet C-2.2. this was also mentioned in my ‘No Practical Alternatives’ and ‘Response to AIR 2013-09- 12’, attached. Soil borings, specifically hand auger borings #7 and #8 downstream of the dam (refer to attached geotechnical report) indicate soils are moist, but not saturated, until 3.5-4ft below grade (page 3). Any water in the stream is a result of direct runoff or seepage from the dam. I had this specific conversation with the geotechnical engineer and he is confident we can construct this in the dry, draining down the BMP a couple weeks before construction. Please let me know if you have any further questions or comments. Thanks, Chuck From: Homewood, Sue [mailto:sue.homewood@ncdenr.gov] Sent: Monday, October 07, 2013 3:19 PM To: Christy, Charles Subject: RE: Greensboro Charter Academy, DWQ # 13-0780 Chuck, I was going back over everything to draft up the permit and I can’t find where you answered Item #2 on the attached letter I sent. I looked through the plans but don’t see how you will be installing the additional pipe “in the dry”. Of course, I’m reviewing the plans on my monitor and could be missing something. Thanks.

See attached plan review tracking status from the City website. We have watershed protection-storm water approval, storm water conveyance approval, and soil erosion approval. We do not overall approval of the project yet because of an easement release. We have to appear before planning board to release a portion of the water quality conservation easement. Prior to project completion, we will dedicate new water quality conservation easement to replace that portion we asked release of. The planning board will seek input from Virginia and her department regarding this easement release. Based on my discussion with Virginia, she is in favor of the release. I am also attached the latest PCN (forwarded to USACOE) and owner authorization. I believe you have copies of the USACOE permit, City buffer certification, and the no practical alternative narrative. Please let me know if you would like hard copies or if you have any questions. Thanks, Chuck Charles J.
