During 30-percent and 60-percent design review meetings with the City, the City identified and requested a series of changes and additions that require an amendment to RH2’s current scope of work. These changes and additions, which are described below, provide additional benefit to the City by: 1) improving constructability and phasing of the reservoir improvements; 2) improving the site layout to better respond to Hearing Examiner comments and citizen concerns identified during the Conditional Use permitting process; and 3) improving water system reliability and resiliency by replacing and re-purposing 435 and 565 PZ distribution main infrastructure located within the project limits. The changes and additions covered in the Scope of Work below generally include the following. • Approximately 1,500 lineal feet of 12-inch and 16-inch 565 PZ distribution main within NE 12th Street from Olympia Avenue to west of Sunset Avenue, and re-purposing of the 435 PZ 16-inch transmission main within NE 12th Street and west of Harrington Avenue for use as 565 PZ distribution main. • Additional exploratory work, including utility potholing and geotechnical investigation, within NE 12th Street to support the design and construction of the utility and roadway improvements. • Additional design and hydraulic analyses to evaluate closed-zone operation of the Highlands 435 PZ during replacement of the Highlands 435 PZ reservoirs. The design and analyses will primarily focus on upgrades to the Mt. Olivet Booster Pump Station (BPS) to replace the existing booster pump motor starters with variable frequency drives (VFDs) and install a recirculation valve to improve closed-zone operation during replacement of the Highlands 435 PZ reservoirs. It is anticipated that the installation of the proposed improvements will be performed by the City’s Water Department. • Additional design and coordination to provide a video surveillance security system for the Highlands reservoir site. • Revisions to the Master Site Plan and 60-percent design to include the demolition of the existing 2.0 MG reservoir under Phase 1, and reconfiguring the site to increase the buffer and visual screening of the proposed 6.3 MG reservoir from the retirement home community to the north of the property. Except where noted below, the above changes and additions are underway and will generally be completed in accordance with the original contract and Scope of Work.

Tasks 3A and 3B – Services During Bidding (No Change) No change in scope or fee. Task 4 – Additional Design and Permitting Services (No Change) No change in scope or fee. Task 5 – Additional Master Planning and Hydraulic Analysis (New Task) Background: As part of the 60-percent design review process, it was determined that it would be advantageous for a multitude of reasons to remove the existing Highlands 2.0 MG reservoir from service prior to constructing the proposed 6.3 MG reservoir. This represents a change in the original design criteria. Before incorporating this change into the operation of the water system and the current design plans, the City has requested that RH2 perform additional hydraulic analysis and master planning to confirm that fire flow requirements can still be met without the 2.0 MG reservoir in service. The analysis also will evaluate a scenario where the Highlands 1.5 MG reservoir is out of service as well. To facilitate water system operation under this scenario, it is anticipated that improvements will be made to the Mt. Olivet BPS to allow for closed-zone operation. Objective: Confirm, through hydraulic alternative analysis, that the Highlands 435 PZ can maintain a similar level of service if the 2.0 MG reservoir is out of service prior to construction of the 6.3 MG reservoir. Evaluate operation under a closed-zone operating scenario. Identify recommended mechanical, electrical, and control system changes that may be implemented prior to removing the Highlands 1.5 MG or 2.0 MG reservoir from service, and before the 6.3 MG reservoir is constructed. Prepare a technical memorandum that summarizes the findings and recommendations of the hydraulic analyses. Revisit the site master plan and prepare up to two (2) alternative site configurations based on the revised construction phasing and demolition of the 2.0 MG reservoir. Approach: 5.1. Evaluate and perform hydraulic analyses to confirm that the 2.0 MG Highlands reservoir can be removed from service prior to the completion of the proposed 6.3 MG reservoir, while maintaining required fire flows.
