Bankside outtall to accommodate 117 mgd (277 mgd less 160 mgd which is the estimated <br />'. capacity of the existing outfall system after secondary treatment modifications). Includes <br /> landscaping in the disturbed area of the outfall as required to mitigate backside <br /> disturbance. <br />Justification: According to the hydraulic calculations in the Facilities Plari, a new bankside outfall will be <br />', required to pass the peak wet weather flow to the river. <br />Project Driver: According to the hydraulic calculation in the Facilities Plan, after secondary treatment <br /> modifications are made, a maximum peak flow of 160 mgd can pass through the existing <br /> outtall box without submerging the secondary clarifier weirs. CH2M Hillis currently re- <br /> evaluating the hydraulics in this area and will provide better clarification of the timing and <br /> need for this project. <br />Project Trigger. Need to provide peak flow capacity in order to treat peak storm flows without overFlow by <br /> 2010. <br />Project Type: 100% Capacity <br /> <br />Estimated Project Cost: <br />j ~ ?? <br />$3,000,000 <br />Expected Cash Flow: FY 08-09 = $1,100,000; FY 09-10 = $1,900,000 <br />Exaenditure/Category: Prior Years 2007-08 2008-09 2009-10 2010-11 2011-12 Total <br />,__ Design/Construction 0 0 $3,000,000 0 0 0 $3,000,000 <br />~ Other 0 0 0 0 0 0 0 <br />Total Cost $0 $0 $3,000,000 $0 $0 $0 $3,000,000 <br />~ Funding Source: Prior Years 2007-08 2008-09 2009-10 2010-11 2011-12 Total <br />Capital Reserve 0 0 $3,000,000 0 0 0 $3,000,000 <br />EPA Grant 0 0 0 0 0 0 0 <br />SDC Reimbursement Reserve 0 0 0 0 0 0 0 <br />r' SDC Improvement Reserve 0 0 0 0 0 0 0 <br />Equipment Replacement Reserve 0 0 0 0 0 0 0 <br />Total Cost $0 $0 $3,000,000 $0 $0 $0 $3,000,000 <br />Page 73 FY 07-08 BUDGET AND CIP <br />
