Citywide Dredging 332021 1 Why Now Hampton greatest

Citywide Dredging 3/3/2021 1

Why Now? • Hampton greatest Asset is the Water • Hampton Waterways Are Gradually Filling in With Silt From Natural and Man-Made Blocking the Channels and destroying Habitat Which Also Causes Them to Becoming Increasingly Unnavigatible. • The Corps Maintains The Hampton River Channel (Up to the Booker T. Washington Memorial Bridge) and The Southwest Side of Ft. Monroe • The Main and Stem Channels of the Other Waterways Within Our Boundaries Are Becoming More Like “Mud Flats” 3/3/2021 2

Why Now? Continued, • Corrective Action Citywide Dredging Has a Significant Price Tag. • Once We Start The Process It Will Take Several Years Before The Problem Is Fixed. • There Are Still Other Risk and Concerns That Will Have to Be Addressed Before We Decide on a Course of Action. • One such Issue May Be The Dumping Site For Dredged Materials. 3/3/2021 3

What are Our Options? • Dredging Select Waterways Using Contracted Dredging • Developing an In-House Dredging Program 3/3/2021 4

In-House Dredging Concept: • Develop an In-house Dredging Capability • • Using a Long Reach Excavator Mounted on a Barge The Excavator Would Dump The Dredged Material Into Bottom Dump Barges. We would Acquire at Least Two Barges (custom built to be useful under our Bridges). 3/3/2021 5

In-House Dredging Concept: (continued) • We Would Also Need To Acquire A Work Boat to Maneuver the Barges and the Dredge Barge and a Hydrographic Survey Boat. • Our Plan Would Be to Haul The Dredged Material Would to Craney Island Using Contracted Tug Services (owning a tug to haul the barges would be cost prohibitive). • It Is Estimated That We Would Only Be Dredging 600 Hours Each Year. 3/3/2021 6

In-House Dredging Concept: (continued) • The Proposed Personnel Requirements Include Environmental Engineer Boat Captain Dredge Operator 4 -Crew Members (Deck Hands) Hydrographic Surveyor 3/3/2021 7

In-House Dredging Concept: (continued) • Public Dollars Would Be Used to Dredge Main and Stem Channels. • Individual Property Owners Would Have to Hire and/or Pay to Have a Private Channel Dug to Their Pier. • The Mechanics and Coordination of How This Would Work Would Need to be Worked Out Regardless of Whether a Private Contractor Does the Private Channel or If The City Dredge Is to Perform That Work in Conjunction With the Public Dredging. 3/3/2021 8
