About this file
The submitted file is a comprehensive set of engineering plans (Addendum 2) for the Manzanita Classic Street Connection project, prepared by Windsor Engineers for the City of Manzanita, Oregon. The engineering plans detail a roadway reconstruction project spanning approximately 1,600 linear feet along Classic Street, including intricate infrastructure improvements such as water main installation (10-inch HDPE), storm sewer system enhancements, retaining wall construction, pedestrian pathway development, and traffic calming measures. The project documents are dated 5/6/2025, with a project number of 24231, and include detailed grading plans, utility plans, road profiles, signage and striping plans, and specific construction details for elements like guardrails, fencing, and retaining walls.
The project appears to be primarily funded through a State of Oregon grant focused on infrastructure development for affordable housing, with complex construction requirements addressing challenging geological conditions including steep slopes and unique sandy soil characteristics. The engineering plans reveal sophisticated design considerations, such as managing significant elevation changes, integrating utility infrastructure, and implementing specialized construction techniques. The project will require compliance with Oregon Bureau of Labor and Industries (BOLI) prevailing wage rates, and involves careful management of potential material price escalations. The comprehensive nature of the plans suggests a technically demanding infrastructure project that will require specialized construction expertise to navigate the complex environmental and engineering challenges of the Manzanita site.
