Suction Dredge with Dump Scow - Upper Bay
• Actively Pursue a Federal Dredging Project in Lower Harbor to
remove approximately 650,000 cy Legacy Material
➢ Necessary Sediment Testing is Underway
➢ Staff/Council/Harbor Commission Engaging Elected
Representatives, Army Corps, and Regulatory Agencies
➢ Requesting $400,000 in 2019 Army Corps Budget for Design
• Work with County to set aside funds to Dredge County Tidelands
➢ North and South of PCH
➢ Possibly Join the Larger Project
Some Thoughts On A Game Plan
Addressing Annual Maintenance Dredging (slips, beaches, shoals, etc.)
? Explore Modifying RGP (Nearshore Dredging) to allow Small
Quantities of Material Disposal into Channels prior to Large Project
*(provided this is agreeable with Corps & Regulatory Agencies)
➢ Permitted for Small Cost Recovery Fee
➢ Larger Dredging Project later Removes Material at Lower Bulk Rate
➢ Reduces Disposal Cost to Residents = More Attractive to Dredge
? Consider Contracting, or Purchase/Operating Small Suction Dredge
System for on-going maintenance of Public &maybe Private Areas
