Meeting started: 1:00 PM In Attendance: Zan Price, Landon Davidson, Tim Fox, and Kevin Barnett from DWR Wes Jamison, PE — representing the applicant Mr. Jamison stated that he was here at the request of Rusty McClean, the attorney representing the property owner. Mr. Jamison had looked over the plans but had not seen any of the "additional information" letters from DWR. He wasn't clear on his role with the project. He has not been asked to design any stormwater measures for the project. Zan Price stated that DWR had hoped that Ms. Austin would attend the meeting so we could have a back and forth conversation to resolve any issues we have with the submitted SMP and additional information responses. Additional information letters and the previous meeting in Winston-Salem have not been effective at reaching the goal of getting an approvable SMP. DWR made the following points: • DWR needs a plan that provides 85% Total Suspended Solids (TSS) removal for the site since the proposed development is a high density site. • Dry Detention basins only provide 50 % TSS removal and are inadequate measures for the site. • DWR discussed the email they received from the Army Corps stating that their Regional Conditions do not allow jurisdictional wetlands to be used for stormwater treatment. Additionally, discharging under treated stormwater to a wetland could result in a wetland standard violation from DWR. • Use the Stormwater BMP manual to determine the appropriate structural stormwater controls (BMPs) for the site. Make sure to follow all of the required major design elements of the manual. • The applicant has not provided any seasonally high water table (SHWT) data. The Altamont report they reference provides an estimate of the groundwater depth based on the conditions observed on one day. These depths were not surveyed and they do not represent the actual SHWT. The WL -2 data point from the Altamont report is located adjacent to the 2580' contour line (Figure 3). According to the report, the water table was observed 10" below ground surface on 2/5/14. Therefore, the estimated water table elevation on that day would be approximately 2579.2', which is above the proposed bottom of the two bioretention cells. Bioretention cells must beat least 2 -feet above the SHWT. • DWR advised Mr. Jamison to determine the elevation of the SHWT at the proposed basin locations to inform the selection of the appropriate BMPs. DWR asked Mr. Jamison if any of these requests appeared unreasonable. He stated that he understood that these were the requirements to get an approved SMP. Mr. Jamison is an engineer for the NC DOT and has experience with erosion and sediment control measures. Meeting adjourned: 1:25 PM Zan Price, P.E.
