173 <br /> Erosion and Sedimentation Control: <br /> According to current Orange County GIS imagery of the project parcel, there are <br /> approximately six (6) mapped stream features or other water features (e.g. ponds and/or <br /> wetlands) within the project parcel boundaries. Orange County enforces stream buffers <br /> along streams, rivers, water bodies, and other water features (e.g. wetlands) as outlined <br /> in Section 6.13 of the Orange County UDO. Based on the submitted materials for the <br /> proposed development and anticipated limits of disturbance, the project could meet the <br /> basic Erosion and Sedimentation Control requirements as outlined in Section 6.15 of the <br /> Orange County UDO and could be developed as generally proposed. <br /> Stormwater Management: <br /> The project parcel is located in the Cane Creek Protected Watershed Overlay District, <br /> and is therefore subject to compliance with the Jordan Lake Nutrient Management <br /> Strategy. There are no known Special Flood Hazard Areas (SFHAs) located on the <br /> project parcel. Based on the submitted materials for the proposed development, the <br /> project could meet the basic Stormwater Management requirements as outlined in <br /> Section 6.14 of the Orange County UDO. The project proposes the installation of one (1) <br /> permanent primary Stormwater Control Measure (SCM) to meet water quantity <br /> requirements (i.e. post-development stormwater runoff attenuation). The developer will <br /> be obligated to ensure post-development conditions with no net increase greater than <br /> 10% in peak flow leaving the project site from the pre-development conditions, consistent <br /> with 15A NCAC 02H.1002(44). The submitted Stormwater Narrative must be revised <br /> to provide supporting calculations as such. There are no water quality requirements <br /> (i.e. post-development nutrient attenuation) currently associated with the Watershed <br /> Overlay District within which the project site is located. The proposed primary SCM is <br /> currently identified as a Dry Pond. The Site Plan, while preliminary at this stage of Orange <br /> County review, meets applicable stormwater management requirements as outlined in <br /> Section 6.14 of the Orange County UDO and is in general conformance with the North <br /> Carolina Stormwater Design Manual (i.e. Minimum Design Criteria). <br /> Conclusion: <br /> The Division has No Oboections to the approval of the rezoning request so long as a <br /> revised Stormwater Narrative and a complete LDP application and supporting plans and <br /> calculations are submitted to Orange County for review, processing and approval prior to <br /> commencement of on-site Land-Disturbing Activity. As the project progresses with <br /> engineering design, additional field observations, and/or permitting by others (e.g. US <br /> Army Corps of Engineers, NC Department of Environmental Quality, NC Department of <br /> Transportation, etc.), additional buffers, setbacks, and/or additional Orange County <br /> review and permitting may apply beyond the proposed development as shown with this <br /> rezoning request. <br /> 03/0$12023 <br /> Christopher Sandt, PE Date <br /> Steve Kaltenbach Date <br /> Page 2 of 2 <br />
