Pipeline Routes and Operation Narrative
The dredged material must be transported over the designed pipeline routes that may include public roads and property, four wheel
drive trails, navigable and un-navigable water, and under fixed finishing piers. Local authorities will acquire and furnish all permits,
rights-of-way or easements as required for such pipeline routes indicated on the drawings, if required.
Prior to installing the pipeline, the Contractor shall devise and provide a marked-up plan with a special pipeline route that will be used
and obtain the written or verbal approval for the specific pipeline route from the Engineer, in general layout with this piping corridor
plan. The pipeline route shall be devised so as to minimize adverse impacts on vegetation wildlife, dunes, vessel and beach traffic.
Submerged Pipelines: When Contractor elects to submerge his pipeline, the top of the submerged pipeline shall be no higher than
the required project depth depth for the channel in which the submerged pipeline is placed. The location of the submerged pipeline
shall be marked with signs, buoys, and flags to the complete satisfaction of the Engineer. CAMA and the US Coast Guard.
Channel Traffic: Temporary cessation of operations will be necessary for the passage of vessels, while dredging in or adjacent to
the Atlantic Intracoastal Waterway (AIWW) is in progress. Contractor shall post signage, including means or vessels to contact the
captain of the dredge.
Obstruction of Navigation Channel: The Contractor will be required to conduct the work in such manner as to obstruct navigation as
little as possible, and in case the Contractor's plant so obstructs the channels as to make difficult or endanger the passage of
vessels, said plant shall be promptly moved on the approach of any passage. Upon the completion of work, the Contractor shall
promptly remove his plant, including ranges, buoys, piles, and other marks placed by him under the contract in navigable waters or
on shore.
Contractor shall coordinate all work with the US Coast Guard.
