<br />develop height required for rink levee, and evaluate access during <br />periods of Diversion operation. <br />b. The ring levee will impact the golf course and clubhouse. Provide <br />conceptual design services for re-design of the golf course and <br />clubhouse. <br />i. Provide an updated conceptual design of golf course and <br />clubhouse based on update levee alignment to accommodate <br />a total of 80 replacement residential lots. <br />c. Initial Survey and Geotechnical Activities for Levee Design: <br />i. Work with USACE to develop a geotechnical investigation <br />plan for the alternative Levee alignments for approval. <br />ii. Stake the location of approved borings and record the <br />coordinates and elevations of the borings. <br />iii. Conduct up to 20 geotechnical borings on portions of the <br />alternative alignments that are common to all alternatives. <br />iv. Obtain and comply with right of entry (ROE) and right of way <br />(ROE) requirements for each property entered. <br />The construction of the Oxbow/Hickson/Bakke (O/H/B) ring levee and <br />associated work is phased. The work has been divided into five (5) Work <br />Packages, which include: three (3) levee design packages, an interior drainage <br />and road raise package, and a demolition and utility relocations package. One <br />of the levee design packages (WP-43B) will be completed by the USACE. The <br />remaining 4 design packages (WP-43A, WP-43C, WP-43D and WP-43E) will be <br />completed in this scope of work. See Figure 1, attached. <br />Assumptions for WP-43A, WP-43C, WP-43D and WP-43E include: <br />• No additional surveys required (included in WP- 43B). <br />• Soil exploration, laboratory testing, and instrumentation costs <br />included under WP-43B. Geotechnical design of the levee is required. <br />Groundwater evaluation is required to determine impacts to existing <br />septic systems, sewer systems and basements. <br />• No staging area water hydrologic and hydraulic (H&H) modeling <br />required (included in WP- 43B). H&H for local drainage and interior <br />drainage is required. <br />• Include design of levee, vegetation free zone, and ditching (input from <br />WP-43B and WP-43D). CR-81 road raise will be in WP-43D. Retention <br />basin/pump station design will be in WP-43D. Utility relocation design <br />and demolition design will be in WP-43E. <br />• Coordination between designers for WP-43B, WP-43C, WP-43D, and <br />WP-43E is required, along with review of design submittals from WP- <br />43B. <br />• Develop design, plans, ROW drawings, technical specs, Design <br />Documentation Report (DDR), cost estimate, and engineering <br />considerations. <br />HMG-TO-13-A4_Long.docx 6 <br />DR <br />A <br />F <br />T
