Site work and paving for a road / highway in Mill Creek, Washington. Conceptual plans call for site work for a road / highway; and for paving for a road / highway.

The July 2021 Pavement Management Analysis Report by Infrastructure Management Services identified segments of streets that had Pavement Condition Indicies (PCIs) in the 50 to 60 range (corresponding to a "Fair" to "Good" condition). These conditions are nearly at the minimum level of service called for in the 2015 Mill Creek Comprehensive Plan. Pavement preservation methods are still feasible for streets with this level of condition, but generally involve much more extensive full-depth pavement replacement panels, areas of street subgrade reconditioning and recompaction, and similar project elements more expensive and longer in construction duration than a typical thin- to medium-overlay project. This project to overlay and rehabilitate the condition of Trillium Blvd is one example. This work will generally include grinding and full-width milling of at least the upper 3-6 inches of street surface for much of the area, removal and replacement of panels of asphalt requiring full depth replacement, regrading and recompaction of the street in full-depth replacement areas, placement of new asphalt, adjustments of utility lid rims, and restriping. Where removed by overlay activities, traffic signal detection loops will also be replaced. Unlike most pavement preservation overlay project, this project includes all associated ADA-required street and sidewalk improvements to be compatible with changes/adjustments in finished pavement surfaces. This project is included in the City of Mill Creek's FY 2023-2028 Capital Improvement Plan (CIP) As of March 15, 2023, information regarding a design team or a general contractor is not available. Construction is anticipated in 2026.* *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change.
