For this PL-566 Watershed Project, the work may include, but is not limited to: Acquiring appropriate project permits, access road determination and development, sediment removal and transport to on-site or off-site location, debris disposal and transport to on-site or off-site location, and engineer design. Work will be completed to remove sediment and debris from an existing structure to increase water storage capacity. Items to consider for sediment removal and disposal are: adequate buffer between the removed soil pile and any streams, ditches, watershed, or other waterways, and needed sediment and erosion control measures for the removed soil pile (ex: sediment fencing). Possible option for sediment disposal would be digging excavation pits to bury sediment on the same tract of land, locations will be specified on maps of possible disposal sites on tract. Excavated soil from pits would be used to stabilize access road with any excess excavated soil not needed on site being hauled offsite. Local Waste Transfer Station option available for excess soil disposal (not sediment removed from pond) – 6.2 miles from project site. Remove and dispose of vegetative debris, including dead trees, located 25-30 feet up the banks of the structure Any temporary or permanent material to be stored near the watershed shall be placed at a distance equal to the depth of the watershed structure, but not less than 12 feet from the edge of the water. Disturbed areas will need to be restored and when applicable, use Natural Resources Conservation Service CPS 342 Critical Area Planting guidelines. Implement adequate erosion and sediment control measures around spoil piles and areas disturbed by project activities. Debris removed from watershed structure must be removed from the 100-year flood plain as determined by flood mapping technology systems such as FEMA Flood Insurance Rate Maps. Landowner may choose to dispose of material on their land or contractor will be required to dispose offsite. Removal of woody material will be in accordance with the Woody Debris Removal Guidelines starting on page B1 of the document titled “Incremental Effects of Large Woody Debris Removal on Physical Aquatic Habitat”.
