Includes funds for landscaping in vicinity of facilities. <br />Justification: An estimated 30 mgd of filters is required by 2010 to meet dry season mass limits. Facility Plan <br />proposes phasing filters in sooner to facilities. development of Level 3 and Level 4 reuse. <br />Provides high quality secondary effluent and potential level 4 reuse water. Also, needed to assist <br />with meeting wet season mass load requirements during peak flow events (under all peak flow <br />management alternatives). <br />Project Driver: Performance reliability to meet the dry weather NPDES total suspended solids limits of less than <br />10 mg/L, reuse development, and compliance with peak flow management. <br />Project Trigger: NPDES permit compliahce for TSS: Dry weather maximum month flow in excess of 49 mgd. <br />Also, initially to provide higher quality effluent so that reuse can be developed. <br />Project Type: 25% Capacity; 75% Performance <br />Estimated Project Cost: $14,685,000 <br />Expected Cash Flow: FY 07-08 = $1,500,000; FY 08-09 =. $8,500,000; FY 09-10 = $4,685,000 <br /> Prior <br />Expenditure/Category: Years 2007-08 2008-09 2009-10 2010-11 2011-12 Total <br />Design/Construction 0 $1,500,000 $13,185,000 0 0 0 $14,685,000 <br />Other 0 0 0 0 0 0 0 <br />` Total Cost $0 $1,500,000 $13,185,000 $0 $0 $0 $14,685,000 <br /> Prior <br />Funding Source: Years 2007-08 2008-09 2009-10 2010-11 2011-12 Total <br />4 Capital Reserve <br />~. ; 0 $1,500,000 $11,785,000 0 0 0 $13,285,000 <br />EPA Grant 0 0 0 0 0 0 0 <br />SDC Reimbursement Reserve 0 0 0 0 0 0 0 <br />SDC Improvement Reserve 0 0 $1,400,000 0 0. 0 $1,400,000 <br />Equipment Replacement <br />Reserve 0 0 0 0 0 0 0 <br />Total Cost $0 $1,500,000 $13,185,000 $0 $0 $0 $14,685,000 <br />Page 69 FY 07-08 BUDGET AND CIP <br />
