2. PROJECT DESCRIPTION AND SCHEDULE

2.1. Project Site, Vicinity, and Schedule

The National Park Service, in cooperation with the Western Federal Lands Highway Division (WFHLD) of the Federal Highway Administration, is planning to repair part of Washington State Route 123 from MP 10.5 to MP 16.3 and State Route 410 from MP 65.6 to 67.0. WA SR123 serves as the primary access to the north, east and south sections of the Mt. Rainier National Park. WA SR 410 serves as one of the five primary east-west cross Cascade highways that links the Puget Sound and Yakima areas in the state. The existing condition of the roads is poor. Frost heaving and infiltration of water into the base, subbase, and embankments have all contributed to the continuing deterioration of the road and the need for improvement.

This project will consist of recycling and overlaying the roadway within the project limits along the existing alignment. The existing pavement will be recycled in place and used as base course. A new lift (2” depth) of hot asphalt will be constructed over the recycled base. Approximately 23 turnouts will be redesigned, with a small change in the footprint. Approximately 8,100 square yards of roadway will be obliterated. All disturbances are within the existing roadway, including the turnouts.

Where base and subbase material has become saturated and frost heaving has occurred, the subbase will be dug out and replaced with suitable material. These digouts will occur in approximately 3 locations. The subexcavation at each site will be confined and then backfilled in the same work shift. Ditch and culverts will be cleaned as needed to reestablish proper drainage. Approximately 89 culverts and 15,000 feet of ditches will be cleaned.

2.2. Narrative Sequence of Major Activities

The following activities will be performed by the Contractor unless otherwise noted.

1. Mobilization, installation of erosion control, and construction signage.

2. Subexcavation areas, culvert repairs, ditch reconditioning, turnout and parking area improvements.

3. Pavement pulverization and aggregate base installation.

4. Paving, striping, and guardrail installation.

5. Revegetation

6. Site cleanup

I-5

2.3. Disturbance and Off Site Activities Activities

The total area of work, including resurfacing as well as actual ground disturbance, is 31.0 acres. Actual ground disturbance associated with ditch work, shoulder grading, subexcavation, turnouts, and culvert replacement is approximately 4.3 acres.

Details showing BMP use and locations, as well as disturbance areas, can be found in the contract plans and specifications.

5.2. Product-specific Storage Practices to be Followed Onsite

Petroleum: Stationary diesel and gasoline tanks will have containment area.

Fertilizers and Pesticides: No long-term storage at the project site.

Hazardous Materials: Substances will be labeled and stored in proper containers at least 100 feet from surface water streams.

Other:

5.3. Additional Best Management Practices

In addition to the good housekeeping and material management practices discussed in the previous sections of this plan, the following best management practices (BMPs) will be followed for spill prevention and cleanup:

A Spill Prevention, Control, and Countermeasure Plan will be required prior to starting construction.

6. MAINTENANCE AND INSPECTION PROCEDURES

The FHWA will have a full-time Project Engineer (PE) on the project. The PE will conduct routine and weather-related inspections to ensure compliance with the proposed plan.
