Construction details provided in this standard plan are NOT drawn to scale. 2. These details are for lots with less than one acre of land disturbance. 3. If the land disturbance on a single lot is greater than one acre, a custom plan should be submitted for the 30-day review cycle that addresses berms/diversions and sediment storage traps and basins. 4. This document is a guideline to control sediment onsite for single family lots with a disturbed area of less than one acre. Additional sediment control measures may be needed on a site-by-site basis. 5.
