Public works previews 2025 Pavement Management Strategic Plan; contract to be returned April 15
Summary
Public Works presented a preview of the city's 2025 Pavement Management Strategic Plan, proposed assessment scope, and community-engagement schedule. Staff expects to return a consultant contract for council approval April 15 and will use the plan to set condition targets, funding priorities and an equity-informed selection process.
Sammamish Public Works staff presented a preview April 1 of the city’s 2025 Pavement Management Strategic Plan, an update intended to set policy targets, inventory right-of-way assets, and establish funding and project-selection priorities for roadway preservation and rehabilitation.
"Pavement condition index is the universal scoring, with 100 being brand new asphalt," Deputy Director Greg Stomantio told council, describing the condition-assessment methodology staff will use. He said the city’s last technical assessment (2021) showed generally good pavement condition citywide and that the consultant TransMap is expected to lead the field data collection and analysis for the 2025 update.
Audrey (staff) described four focus areas for the strategic plan: a current-condition assessment, maintenance and operational strategies, equitable prioritization of streets, and funding strategy analysis. The plan will also pilot the city’s new racial equity toolkit to inform how streets are prioritized and how public engagement is conducted.
Staff said the planned contract will include not only PCI (pavement condition index) mapping and analysis but also a GIS update of right-of-way assets (sidewalks, signs, lighting) and an evaluation of current treatment methods. The timeline presented calls for a contract authorization on April 15, field data collection and inventory in May–June, public engagement in August, a September study-session presentation to council, and plan adoption by the end of the year.
Council members asked about longer-term planning, alternative treatment technologies (chip seal, fiber-reinforced mixes), grant availability and public engagement. Staff said pavement-condition assessments are typically done every two to four years and that the plan will evaluate treatment-cost tradeoffs and identify funding scenarios for maintenance and reconstruction.
Staff emphasized that the plan is intended to provide a five- to ten-year foundation for maintenance decisions, help set minimum and target PCI goals and create a transparent street-selection process with an equity lens. No formal action was required April 1; staff will return on April 15 with a proposed consultant contract for council approval.
