SECTION 6 Integrated Stormwater Management Strategy Footnote to Summary of Strategy Implementation and Costs: Public outreach conducted in October 2009 included comments regarding the size and scope of the flood control capital projects based upon the basin planning modeling and recommended by the RR -SC Plan. The current model is the best fit based upon the best available information and professional engineering judgment, and is likely somewhat conservative for reasons notes in Section 3 as well as the degree of "informal" infiltration in the RR -SC basin. Resource and data limitations inherently limit the level of detail and resolution of the model, and further model refinement would not be appropriate in the absence of better data and additional resources to refine the model. The City and County believe that further refinement to the model based upon measured flow data would be beneficial to confirm capacity issues on the major system related to the larger capacity enhancement and storage CPs. Installation of a flow meter is planned in the RR -SC basin, and would realistically precede detailed design and implementation of these larger CPs. 0:\25695978 Eugene RR -SC Final Basin P1an\Master P1an\FINAL 2- 2010\Master_Plan 3-11-10 FINAL Word Version AW Sec 2 Corr.doc < —O Capital Project Identification Total Estimated Capital Project Implementation Cost WO -2 — Willamette Overflow Flood Control East of Edgewood Dr. $22,500 WO -3 — Willamette Overflow Flood Control East of Yvonne St. $27,800 WO -4 — Willamette Overflow Open Channel Improvements $521,200 WO -5 — Willamette Overflow Flood Control (Storage) at River Avenue $15,630,200 WO- I -UIC — UIC Decommissioning Green UIC Cluster $111,000 WO -2 -UIC — Cluster UIC Decommissioning Corliss /Carolyn/Onyx UIC $537,700 WO -3 -UIC — Cluster UIC Decommissioning Autumn/Ross/Moore -Oak UIC $1,337,100 WO -4 -UIC — UIC Decommissioning Taz UIC Cluster $124,500 WO -5 -UIC — UIC Decommissioning Silver Meadows UIC Cluster $404,400 WO -6 -UIC — UIC Decommissioning Poplar UIC Cluster $390,600 WO -7 -UIC — UIC Decommissioning Kendra UIC Cluster $75,600 WO -8 -UIC — UIC Decommissioning Kent UIC Cluster $397,000 WO -9 -UIC — UIC Decommissioning Baywood UIC Cluster $138,000 WO -10 -UIC — UIC Decommissioning Greenwood UIC Cluster $138,000 WO -1I -UIC — UIC Decommissioning Warrington UIC Cluster $138,000 Subtotal: $20,139,200 TOTAL: $66,156 Footnote to Summary of Strategy Implementation and Costs: Public outreach conducted in October 2009 included comments regarding the size and scope of the flood control capital projects based upon the basin planning modeling and recommended by the RR -SC Plan.
