An entry drive, walled garden and motor courts will contribute to the total impervious areas. A. Quantifying Land Disturbances And Changes In Impervious: The Limits of Disturbance (LOD) for this phase of the project is 2.6 AC and encompasses all required site improvements for this phase of the project. B. Watershed Protection Overlay: Per Jackson County, the site is outside all watershed protection overlay districts. C. Streams: There are no streams that run within the LOD or within the property. D. Floodplains: The property is outside the 100-year flood zone. There are no proposed impacts to the 100-year flood zone with this development.

PORTABLE TOILETS 1. Install portable toilets on level ground, at least 50 feet away from storm drains, streams or wetlands unless there is no alternative reasonably available. If 50 foot offset is not attainable, provide relocation of portable toilet behind silt fence or place on a gravel pad and surround with sand bags. 2. Provide staking or anchoring of portable toilets during periods of high winds or in high foot traffic areas. 3. Monitor portable toilets for leaking and properly dispose of any leaked material. Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace with properly operating unit. EARTHEN STOCKPILE MANAGEMENT 1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least 50 feet away from storm drain inlets, sediment basins, perimeter sediment controls and surface waters unless it can be shown no other alternatives are reasonably available. 2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of five feet from the toe of stockpile. 3. Provide stable stone access point when feasible. 4. Stabilize stockpile within the timeframes provided on this sheet and in accordance with the approved plan and any additional requirements. Soil stabilization is defined as vegetative, physical or chemical coverage techniques that will restrain accelerated erosion on disturbed soils for temporary or permanent control needs. 12' MIN.
