PART 1: GENERAL

1.1. SUMMARY

A. Description of Work: All work shall occur in the BLM, Idaho Falls District, Pocatello Field Office, Morgan Bridge Riparian Restoration Project Area. The Contractor is responsible for furnishing labor, equipment, supplies, and materials to design and construct riverbank stabilization, riverbank recontouring, riparian vegetation plantings, and replacement of an existing culvert with a fish friendly structure capable of withstanding vehicular traffic.

1. Bank Stabilization: Design and construct bank stabilization and rehabilitation plan. The

Contractor shall be responsible for identifying areas in need of stabilization along the riverbank within the project location. The Contractor shall submit the identified areas for Government selection and approval. Work shall be focused on BLM managed lands within the Morgan Bridge Riparian Restoration Project north of Morgan Bridge Campground. Design shall not exclusively include traditional hardened armoring of the riverbank to diminish the erosion along the acquired parcel. The design shall focus on non‐traditional non‐hardened armoring bank stabilization methods and vegetation plantings to alleviate erosive pressures located along the river’s bank.

The Contractor is responsible for the following:

a. Performing a site survey of the riverbank and channel along the Blackfoot River within the boundaries of the Morgan Bridge Riparian Restoration Project Area as identified on included maps,

b. Ensuring that all work is conducted on BLM managed lands, and

c. Filing for and obtaining appropriate permits for in‐stream work, such as the

USACE 404 permit.

2. Bank Recontouring: Design and construct riverbank recontouring and rehabilitation along the BLM, Idaho Falls District, Pocatello Field Office, Morgan Bridge Riparian Restoration Project Area north of Morgan Bridge Campground. The Contractor shall be responsible for identifying areas in need of recontouring along the riverbank within the project location. The Contractor shall submit the identified areas for Government selection and approval. The design shall focus on recontouring the existing riverbank and vegetation plantings to alleviate erosive pressures located along the river’s bank.

The Contractor is responsible for the following:

a. Performing a site survey of the riverbank and channel along the Blackfoot River within the boundaries of the Morgan Bridge Riparian Restoration Project Area as identified on included maps,

b. Ensuring that all work is conducted on BLM managed lands, and

c. Filing for and obtaining appropriate permits for in‐stream work, such as the

USACE 404 permit.

3. Riparian Vegetation Plantings: Design and install riparian vegetation plantings. The Contractor shall be responsible for identifying areas in need of vegetation plantings along the riverbank within the project location. The Contractor shall submit the identified areas for Government selection and approval. Plantings may consist of approved herbaceous and/or woody species. Riparian vegetation plantings may be completed in concert with either bank stabilization and/or bank recontouring work, though is not limited to those locations.

4. Culvert Replacement: Remove existing culvert and design and construct a fish friendly structure capable of supporting full sized vehicular use.

The Contractor is responsible for ensuring that all work conducted and infrastructure installed is on BLM managed lands.
