April,
The proposed sewerline installation at Ravenswood Reserve will meet the conditions of GC4086. Since the wetland
crossing is greater than 150 feet, anti -seep collars will be constructed using one of the approved materials and will be
placed every 150 feet within the wetland. The sewerline corridor will be mechanically cleared and contours within the
wetland will be restored to current elevation and stabilized with vegetative cover. Any excess material will be moved
and disposed in the upland area on the property.
Please contact me if you have any additional questions or comments. Thanks for your help with this project.
Robert
