1.0 PROJECT DESCRIPTION <br />Start Construction - 2007 (pending funding availability) <br />Duration -The project can be constructed in approximately 6 - 9 months depending upon <br />the availability of funding to complete projects. Earliest completion time is 2008. <br />Service to Oyster Bay Regional Park (Phase 2) <br />Start Design - 2007 (pending funding availability) <br />Start Construction - 2008 (pending funding availability) <br />Duration -Approximately one year, earliest completion time is 2009. <br />CONSTRUCTION METHODS <br />PIPELINE CONSTRUCTION <br />In total, the City is proposing to construct approximately 1.3 miles of 18-inch diameter pipeline <br />within City-owned or County-owned public easements, road right-of-ways, and parking areas. <br />Open Trench <br />Standard installation of the pipeline would proceed at the rate of approximately 200 feet per day. <br />For work within roadways, trench width would be approximately four feet, with active work areas <br />of about eight feet on one side of the trench and 10 to 12 feet on the other side for access by <br />trucks and loaders; resulting in a construction easement approximately 20 to 30 feet wide. For the <br />purpose of this analysis, a construction easement of up to 30 feet is assumed, and is used as the <br />Area of Potential Effect (APE) for evaluating environmental impacts. Damage to roads and <br />unpaved areas would be repaired. Disturbed areas would be revegetated with native plants <br />indigenous to the disturbed area. <br />Bare and Jack Undercrossings <br />Bore and jack construction is used to install a pipeline beneath a road, waterway, railroad track, <br />or other surface feature. Bore and jack methods usually employ a horizontal boring machine or <br />auger that advances the tunnel bore. Jacking methods involve installing a pipeline by pushing <br />pipes through the ground with large hydraulic jacks situated within a jacking pit at one end of the <br />crossing to a receiving pit at the other end of the crossing. Table 1-2 indicates locations where <br />bore and jack construction would be used. <br />Suspending Pipe from Bridge <br />Suspending a pipe from a bridge, proposed as part of the Northern Pipeline Route for providing <br />recycled water to Oyster Bay Regional Park, requires suspending a casing pipe from the side of <br />the structure of the bridge and running the recycled water pipeline through the casing pipe.
