While originally it was planned that the project would be bid as a single project, the City has divided the project into multiple phases that will be bid and constructed separately. The two phases are generally described as follows. • Phase 1: 435 Zone and 565 Zone Water Main and Off-Site Utility Improvements • Phase 2: Highlands 435 Zone Reservoir Due to the numerous public and private utilities within NE 12 th Street roadway corridor, the City has decided not to replace the existing 16-inch low-pressure 435 Zone water main with a new 24-inch main as originally planned. There is a greater risk for potential damage to existing critical utilities from deep excavation required for the construction of a large diameter transmission water main. The City anticipates that the existing 16-inch ductile iron water main has a remaining useful life of perhaps 50 years. Instead, the City intends to install approximately 3,700 linear feet (lf) of new 12- inch high-pressure (565 Zone) transmission main in NE 12th Street from Edmonds Avenue NE to Queen Avenue NE to accommodate several current and future major redevelopment projects in the Highlands area, including the Solera mixed-used development. This Amendment is an authorization to modify the project Scope of Work and Fee Estimate (Exhibit C2-8) as described below to provide services necessary to revise the design and complete permitting and bidding efforts associated with Phase 1. Design for Phase 2, which is at approximately 90-percent completion and will be affected by these changes, is on hold pending the completion of the Phase 1 design and bidding. A subsequent budget amendment for Phase 2 will be submitted at a later date to address final design and permitting changes and final integration with Phase 1 improvements.

The following work is included in this subtask: a) Incorporate Changes Related to Recent Construction: Coordinate with the City to identify and obtain construction record drawings of recently completed and/or pending development projects that are within or intersect the project limits. Update base map drawing and existing utility models to incorporate changes in utility locations and condition as documented in record drawings. Coordinate with the City to identify and reconcile discrepancies between GIS and survey/record drawing mapping of utility. This subtask assumes, at a minimum, the following recent projects: Solera Private Development; NE 16th St-Jefferson Ave NE Stormwater Green Connections; Kiddie Care Private Development; a 28-Lot Subdivision, and Puget Sound Energy Gas Main Relocation. b) Incorporate Available Pothole Information: Coordinate with the City to identify and obtain available pothole information related to recent utility and development projects. Update base map plan and profile drawings to reflect pothole information provided by others where sufficient data is available. c) Incorporate Additional Side Sewer Information: Coordinate with the City to review and confirm the depth and location of existing side sewers crossing the proposed utilities. Update base map plan and profile drawings to reflect current side sewer information where new and sufficient data is available. Prepare Stormwater Design Drawings: The City has identified the need to construct stormwater improvements within NE 12th Street to resolve existing capacity issues and eliminate duplicate stormwater collection systems that are contributing to right-of-way congestion affecting the proposed water main improvements. The proposed improvements under this subtask will generally include the following: • Modify approximately 1,700 lf of storm collection system to re-route and abandon the existing 12-inch storm between Edmonds Avenue and Kirkland Avenue and transfer stormwater collection to the existing 36-inch storm. • Replace approximately 300 lf of existing 12-inch storm with proposed 18-inch storm pipe to address capacity issues between Kirkland Avenue NE and NE Sunset Boulevard. • Upgrade approximately 500 lf of existing 12-inch concrete storm pipe to polypropylene from NE Sunset Boulevard to Monroe Avenue NE and update vertical and horizontal locations (as necessary) of the currently proposed, approximately 600 lf of 12-inch storm system from Monroe Avenue NE east to the reservoir site to accommodate reservoir site stormwater and the controlled release of reservoir overflow and/or drain water. City of Renton – Highlands 435 Pressure Zone Reservoir Improvements Replacement of Highlands 435 Pressure Zone Reservoir and Mains Amendment No. 8 Final Design and Bidding Exhibit A-8 Phase 1 – Highlands 435/565 Zone Water Main and Off-Site Utility Improvements Scope of Work 5 5/5/2023 2:15:03 PMZ:\PROJECTS\DATA\REN\113-104\00 CONTRACTS AND PM\PROJECT SCOPING\FINAL DESIGN - AMENDMENT 8\PSA_AMEND NO. 8_EXHIBIT A-8_SOW_FINAL DESIGN AND BIDDING_REV1.DOCX The City has evaluated the adequacy of the conveyance capacity of the proposed configuration of the storm system, outlined above, within NE 12th Street to accommodate street runoff, reservoir site stormwater conveyance, and the managed release of reservoir overflow and/or drain water. The City will document these findings with a technical memorandum that will serve as the basis for the final improvements. The current design of the proposed Highlands Reservoir overflow/drain system is based on the original preliminary design that called for the existing 435 Zone transmission main to be replaced and repurposed to convey flows to the sanitary sewer within NE Sunset Boulevard. The reservoir overflow/drain improvements will need to be further evaluated during the final design of the reservoir and are expected to be included with the Phase 2 amendment. In general, it is assumed that the proposed reservoir overflow/drain design will be revised to discharge to the stormwater system in NE 12 th Street at a controlled rate that will be established by the City in the above-referenced technical memorandum. In the event that the stormwater system is unable to convey the overflow rate from the reservoir, it is assumed that any excess water will need to be temporarily detained onsite and then discharged at the controlled rate. The following work is included in this subtask and includes development of the design up to 90-percent completion. Work associated with advancing the design from 90-percent to 100-percent (bid ready) is included in Task 1.15. a) Prepare 60-Percent Storm Design: Prepare plan and profile drawings for proposed storm relocation and improvements and incorporate into current set of design drawings. Prepare section profiles at each proposed storm crossing. Prepare preliminary detail drawings and schedule of bid items with quantities for proposed improvements. b) Prepare 90-Percent Storm Design: Incorporate and respond to City 60-percent design review comments and advance stormwater design to a 90-percent completion level. This task assumes that no stormwater bypass plans, stormwater calculations, or reporting are required or will be provided as part of these improvements. Update bid schedule and quantities based on 90-percent design and coordinate with the City’s Special Provisions for the project. Update Water Main Design Drawings to 90-Percent: The proposed water main improvements under this subtask will generally include the following: • 565 Zone improvements include approximately 3,700 LF of new 12-inch water main from Edmonds Avenue NE to Queen Avenue NE including connections to existing water mains withing the side streets of NE 12th Street within the same pressure zone. • Provide additional modifications to the existing water system to isolate and temporarily cap HLD 565 water mains in the side streets along NE 12th Street prior to water main construction, including provisions to supply temporary water service to existing customers.

The 435-Zone transmission main replacement will be re-evaluated at a later date with an alignment favoring northern and then western corridors along NE Sunset Boulevard. • Coordinate the revised design for the proposed water mains with the proposed stormwater improvements and the City’s proposed fiber optic communication conduit accordingly. The following work is included in this subtask as necessary to revise and update the watermain design up to 90-percent completion. Work associated with advancing the design from 90-percent to 100-percent (bid ready) is included in subtask 1.15. a) Review Utility Improvements within the NE 12th Street Corridor: Assess different levels of utility improvements within the NE 12th Street corridor based a variety of constraints including, but not limited to, construction phasing, utility maintenance, and corridor management. Meet with the City three (3) times to review alternative solutions for the proposed utility improvements. Prepare and provide background information and engineering opinions to support the further development and amendment of the project scope and design. This subtask was completed concurrently with the development of this Scope of Work and no additional effort is budgeted. b) Update Hydraulic Analysis and Documentation: Perform additional 435 Zone analysis to support continued use of the existing 435 Zone transmission mains, to determine transmission requirements (present and future) from the new reservoir, and to confirm fire flow availability level of service. Outline future improvements to be made outside of the NE 12th Street corridor and the triggers for when improvements should be made. It is assumed that future transmission needs in the 435 Zone will be directly connected to the new reservoir, will leave the reservoir site near the northwest corner, and will ultimately be routed through the NE Sunset Boulevard corridor. Prepare a technical memorandum documenting the results of the analysis and clarify the changes to the basis of design. c) Update Temporary Isolation and Water Service Plans: Update and prepare design plans detailing construction requirements needed to temporarily isolated the existing water mains within the side streets of NE 12th Street that will facilitate reconnection to the new main. In general, it is anticipated that the existing water main can be isolated through temporary cutting and capping of branch mains and without additional provisions for temporary water service.
