Projects for the Safety Plan are identified by compiling fatal and serious injury crash data provided by WSDOT as well as an analysis of the infrastructure around incident sites including safety features, signage, pavement conditions, road geometry, and drainage. Projects are developed utilizing this strategy and ranked by county staff on several conditions. DISCUSSION: Through analysis of this data, Public Works anticipates this year's Safety Plan to include the following: Kittitas Hwy at No. 6 Road Intersection Improvements. Public Works has made several incremental improvements at the intersection over the last few years, but the criteria (specifically crashes in the last 5 years) evaluated in the Safety Plan still identifies a need at this location. This project would identify a large-scale capital improvement project at the intersection. Huntzinger Guardrail Phase 2. Public Works is currently in the design phase for guardrail improvements on the first phase of improvements addressing approximately half of the road segment. This project would look to fund the remaining road segment. Corridor Improvements Countywide. The compiled data shows a trend of serious accidents which happen on certain high -volume roads throughout the County including Look Road, Hanson Road, Cove Road, Bullfrog Road, etc. which could be mitigated with minor improvements to the corridor. Improvements may include embedded LED markers, roadway edge -line rumble strips, and/or carsonite delineation markers to enhance visibility. The low cost of these improvements makes bundling several projects together an option for addressing several high -risk areas at once. Denmark Road Corridor Improvements. Denmark Road from Tjossem Road to Fourth Parallel Road has several safety concerns including narrow structures, non -compliant horizontal and vertical curve, and drainage concerns. This project would address all identified safety risks within this corridor. Bridge and Structure Improvements. Throughout the County there are numerous bridges and structures with identified safety concerns including unprotected side slopes and narrow lane widths. This project may include a County Wide evaluation of existing structures, as well as an implementation phase to address the safety concerns specifically. Public Works intends to present the complete Safety Plan for adoption at the regular Agenda session on March 4, 2025, in order to submit applications for funding by the March 15, 2025, deadline. FISCAL IMPACTS: Previous HSIP projects have been authorized for 100% Federal Funding if the County obligates the construction funding within approximately 2.5 years of award.
