~~ l DRAFT -CONDITIONS OF APPROVAL - BUCKHORN VILLAGE May 7, 2008 iii. Supporting engineering calculations will be submitted with the erosion control plan. c. Compliance with erosion control requirements will be performance based. The developer will install and maintain devices to adequately maintain sediment on- site. Additional controls will be required if off-site sedimentation occurs, even if the site is in compliance with the approved plan, d. The developer shall collaborate with County staff during the erosion control plan design process. To encourage this, a minimum of one (1)pre-application meeting with erosion control staff will be conducted prior to submittal of the ECP, and a pre-construction conference will be conducted prior to land disturbance activities, e. The developer shall adhere to the maximum slope grading standards of 3:1 per Orange County regulations. In cases where a different slope is required to adhere to other local and State requirement, most notably NC DOT driveway access requirements, or a flatter slope is deemed more viable to avoid the wholesale grading of the property or removal of significant vegetation, the developer has the ability to observe a maximum slope ratio of 2:1 so long as: i. The developer can demonstrate on a formally submitted site plan as well as within the grading plan that the reduction will be substantially complaint with the overall intent of County grading and erosion control standards and will not create unnecessary interior, or off-site, impacts ii. That adherence to the established 3:1 slope standard will require excessive grading of the property, iii. That adherence to the established 3:1 slope standards will result in higher velocity stormwater runoff, f. Minimize disturbance and phase development wherever practical. g. The developer shall ensure that any grading activity will be conducted in such a manner that existing vegetation will be preserved and. maintained on the property h. The developer shall utilize the natural shape of the land with minimal grading to locate features in a way that minimize impacts on and off the site. i. The developer shall adhere to NC DOT maximum slope standards for driveways and access drives of a two percent (2%) minimum to a twelve percent (12%) maximum slope where it can be demonstrated on a site plan and on the grading plan that slopes exceeding the current Orange County limit of five percent (5%) are necessary to facilitate safe, pedestrian friendly circulation within the development and individual districts. j. The developer shall ensure that all erosion control devices and designs shall adhere to the Orange County Soil Erosion and Sedimentation Control Ordinance dated Octobex 23, 2007.
