Summary of Attachment 3 - SE Quadrant McCutcheon RD Setback Concept

This document is a conceptual design attachment for the Pierce County Planning and Public Works, Surface Water Management Division's Setback Levee Projects located at 1428 - 128th ST E in Washington. The attachment provides a visual representation and design concept for the Southeast Quadrant McCutcheon Road setback levee project, which is one component of the broader three-quadrant initiative (Northeast, Southwest, and Northwest Quadrants). The consulting engineering firm selected through this competitive qualification process will utilize this conceptual baseline, along with the Exhibit B feasibility study (May 2023), to develop the initial design and delivery strategy followed by complete PS&E designs at 15, 30, 60, 90, and 100% completion levels. Qualifications were due November 25, 2026, and the selected consultant will proceed through multiple design phases as outlined in the attached Scope of Work Summaries.

This conceptual attachment serves as a technical reference document establishing the design framework and site-specific considerations for the Southeast Quadrant component. The document complements the feasibility study and provides engineering teams with preliminary design parameters, site conditions, and configuration details necessary for advancing the levee setback project through subsequent design phases. Prevailing wage requirements under RCW 39.12 apply to applicable public works components, and the consulting firm must maintain professional liability insurance at $1,000,000 per occurrence and commercial general liability coverage as specified in Exhibit A's Professional Services Agreement.
