Dredging Overview Sediment will be mechanically removed byan excavator on a floating work platformconstructed of modular barge sections Dredge area is 160x160 ft ( 0.6 acres) andwill target removal of 1.0 foot of sediment GPS positioning and real time visualizationsoftware will be used to confirm locationand dredge depths Sediment will be transported by barge withperimeter controls (filter fabric, strawbundles) and silt curtains will surround thedredge area to protect water quality Dredge will move between the dredge areaand staging area daily, and storedovernight at staging area Dredging anticipated to takeapproximately 4 weeksDredge Platform EquipmentMaterial BargeDredging Software
Staging AreaDredged material will be temporarilystored at Peach Bottom Road BoatLaunchThe temporary staging area will havethe following: Entrance from Peach Bottom road Trailer, generator, and parking foron-site personnel Soil and erosion control fencing Material management equipment Graded area for dried materialstockpiling Nearshore offloading area
Dorsey Park Boat Launch Equipment launch and removal Temporary closure of oneboat ramp, some parking for1 ½ weeks at beginning and endof the project Closures will be posted in advanceonce schedule is finalized Will remain open during dredgingOther RegionalBoat LaunchOptionsApproximateClosure AreaExample Barge Assembly
Peach Bottom Road Boat Launch Staging Area and materialoffloading location Temporarily closed for up to 2months and will be restoredfollowing project completion Multiple other boat launches areavailable for use during this periodOther RegionalBoat LaunchOptionsApproximateClosure AreaExample Sediment Handling
Primary Trucking Route Dredged material transport willfollow the identified route fromPeach Bottom Road toPerryville, Maryland for reusestockpilingOther equipment to support thedredged material dewatering willarrive from multiple locationsAnticipating approximately70 truck loads to haul materialduring two, 1-week periodsDredge and barge sections willbe mobilized at Dorsey Park
