27.4.CN.01 Inventory Evaluation Matrix_Final.xlsx

This is an Inventory Evaluation Matrix file for ODOT's Region 4 and Oakridge ADA Ramps project (27.4.CN.01), which involves comprehensive accessibility assessments across multiple jurisdictions in Oregon including Bend, Redmond, La Pine, Oakridge, Paisley, Condon, Klamath Falls, and Wasco. The matrix documents detailed evaluations of curb ramp conditions at 95 intersection locations, cataloging accessibility compliance issues, physical obstructions, utility conflicts, environmental concerns, and required remediation approaches. Each ramp location is assessed for deficiencies such as clear width impediments, landing slope problems, running slope issues, and lip height violations. The project encompasses needs identification for new ramps, reconstructions, and ramp modifications across state highways (US97, OR31, OR39, OR58, OR206, OR19) and local connector roads, with disposition categories including parallel ramps, combination approaches, perpendicular configurations, and crosswalk closures. Design considerations include utility coordination requirements, signal protection needs, potential design exceptions, right-of-way impacts, and construction phasing strategies, with multiple ramps flagged for anticipated temporary encroachment permits and specific work area restrictions.

The evaluation matrix identifies significant complexities requiring specialized design and construction engineering support, with particular attention to sites featuring retaining walls, irrigated landscaping, guard rails, signal poles, utility vaults, and infrastructure conflicts that necessitate careful coordination. Multiple locations are flagged for potential environmental considerations including wetland impacts, archaeological monitoring, hazardous materials concerns (former service stations, underground storage tanks), and historic resource preservation. Approximately 60 ramps are designated as in-project with planned remediation approaches including 4(a) New Ramp construction, 4(b) Reconstruction, 4(d) Crosswalk Closure, and combination strategies. Field scoping, design coordination with ODOT, and detailed utility investigation are indicated as necessary for numerous locations. The project scope requires comprehensive Plans, Specifications and Estimates development, construction engineering support, and coordination across multiple agencies including potential consultation requirements with the Army Corps of Engineers, Department of State Lands, and local jurisdictions for right-of-way authorization and access management strategies.
