ATTACHMENT 1 Project Understanding The Indian River County Utilities Department currently supplies water and sewer service to the North Barrier Island via a 12 -inch ductile iron water main and a 12 -inch ductile iron force main, both of which are suspended from the underside of the Wabasso Causeway (CR 510) Bridges . There also exists a 16-inch brine line that currently discharges directly into the Indian River Lagoon under the western-most bridge . This brine line is to be abandoned within the next few months due to its ' discharge point being relocated to the Bent Pine rapid infiltration basin site . Due to the age and structural integrity of the bridge, the age and exposure of the pipes to the weather and the need for reuse water on the barrier island, Utility Services is proposing to replace the existing suspended mains with directionally drilled mains that will be placed under the lagoon bed . The existing 12 -inch water main and 12 -inch sewer main will be replaced with mains of identical size . The existing brine line main will be extended from it ' s current termination point, the western-most bridge, to the east side of the river with a 244nch main and will be converted to a reuse main. This reuse main will then serve to provide reuse water to residential developments on the barrier island, such as Sea Oaks Community, Orchid Island, Windsor and similar developments . The estimated construction cost for the above improvements is $2 . 685 million plus an additional $ 215 , 000 for design, permitting and construction services, for a total project cost of $2 . 9 million. Consultant will endeavor to have the significant portions of the water and sewer pipeline projects completed by next hurricane season 2005 , however, permitting agency responses and contractor delays are beyond our control which may delay completion of these projects beyond hurricane season 2005 . The reclaim line, which is a non critical component of the project will be scheduled to be constructed at a later date, but under the same contractor. Project Approach In general, this scope will include the permitting phase services for the proposed project and the final design construction phase services . Due to the urgency of the project, we will prepare permit applications concurrently with design and bidding phases so as to allow immediate commencement of construction once the permits have been issued . An Environmental Resource Permit (ERP) and Section 10 Permit will be applied for through a joint permit application process through Florida Department of Environmental Protection (FDEP), and the Army Corps of Engineers (ACOE) . The FDEP will ultimately authorize the proposed activity after considering potential natural resource impacts , coastal zone management consistency, potential surface water quality impacts , cultural resource involvement, if any, and the requirements for sovereign submerged land use . The Federal government through the ACOE will consider many of the same issues noted above , but they also will consider potential impacts to navigation within the federally maintained channel . Coordination of the applications will be performed separately but concurrently with each agency to expedite the process . Each agency issues separate permits . 1
