The document provides a detailed assessment of Trestle Creek from MP 100 to 103 in Bonner County, focusing on existing conditions and the impact of bank erosion and stream instability on the roadway. It discusses various sites along the creek (Sites #1 to #4), documenting significant erosion, steep embankments, and the presence of large woody debris as a restoration measure. The analysis highlights bank instability, visible erosion signs, and the implications of stream proximity to the roadway. Additionally, the memorandum addresses the results of in-stream restoration work completed by IDFG in summer 2021, indicating ongoing ecological efforts. Technical data and calculations detail proposed interventions involving log jams and riprap to stabilize banks and improve hydraulic conditions. This memorandum serves as a foundational document for future planning and funding requests related to ecological restoration and infrastructure protection, aligning with federal and state grant initiatives focused on stream and habitat preservation.

The document details the proposed construction project titled "FLAP BONNER 841(1) - Trestle Creek Road" located in Kaniksu National Forest, Bonner County, Idaho. This project involves upgrading Trestle Creek Road through the placement of riprap, roadway aggregate, and asphalt concrete pavement, adhering to the U.S. Department of Transportation's Federal Highway Administration standards. Key elements include a summary of quantities, typical sections, and various layouts related to bank stabilization, erosion control, and temporary traffic management. The project aims to enhance roadway safety and durability while preserving the surrounding environment, which includes measures for tree protection and habitat enhancement. The project manager is identified as B. Stokes from the Western Federal Lands Highway Division. The document serves as a preliminary plan not intended for immediate construction, indicating coordination with existing road structures and compliance with state and federal specifications. The overarching objective is to improve infrastructure while considering ecological factors and adhering to federal guidelines for highway construction and environmental protection.

The project outlined in file ID FLAP BONNER 841(1) involves roadway improvements on Trestle Creek Road in the Kaniksu National Forest, Idaho, spanning a length of 3.75 miles. The planned work includes the installation of riprap, roadway aggregates, and asphalt concrete pavement, among other tasks, with an estimated budget ranging from $5 million to $10 million. The tentative solicitation date for bids is set for Spring 2025, with a completion target of Fall 2025. The project encompasses several divisions including construction requirements, earthwork, slope reinforcement, aggregate courses, asphalt pavements, and incidental construction activities. Specific tasks range from clearing land and removing existing structures to placing riprap, installing asphalt surfaces, and implementing environmental mitigation measures. Additionally, the project incorporates essential construction controls such as dust control, erosion prevention, and traffic management strategies. The outlined details reflect a comprehensive plan for infrastructure enhancement in a federal context, aiming to fulfill regulatory obligations while improving roadway functionality and safety for users in the area.

The Western Federal Lands Highway Division has announced a solicitation for prospective bidders regarding the reconstruction and paving of Trestle Creek Road in Bonner County, Idaho. The project spans approximately 3.7 miles, starting from Highway 200 to the Idaho Panhandle National Forest.
