SPECIFICATIONS:

The Boulder Canyon Multi Use Trail, located immediately west of downtown Boulder, is regularly maintained by Boulder County Parks and Open Space (BCPOS). The 1.9 mile facility includes segments constructed with concrete trail tread as well as sections surfaced with crusher fines.

Originally built in the early 1990s through a partnership among the Colorado Department of Transportation (CDOT), the City of Boulder, and Boulder County, the trail lies primarily within CDOT right of way along Highway 119 and on unincorporated lands owned by the City of Boulder.

A Management and Maintenance Agreement dated December 17, 1992, and a Joint Management Agreement dated December 8, 2005, assign Boulder County responsibility for all capital improvements, including repairs and upgrades to the trail.

The proposed scope of work includes construction of a properly engineered and grouted boulder slope protection wall adjacent to the existing bridge abutment, as well as restoration of the approach trail to its pre scour condition.

The Project Consists of:

1. Construction of grouted boulder slope containment wall.

2. Construction of trail approach impacted by scour and any associate site activities.

3. Reclamation of all disturbed areas with different identified native seed mixes.

Major items of work include, but are not limited to:

1. Secure applicable permits prior to construction startup.

2. Mobilization and project controls.

3. Operation of a curtesy shuttle for duration of project to ensure the public who use the trail to commute have a safe route around the closure.

4. Site preparation includes a pre-construction survey, necessary Best Management

Practices (BMPs)/Stormwater Control Measures (CMs).

5. Access for heavy machinery and materials by way of existing low water crossing East and downstream of concentrated project work site. Return Low Water Crossing to pre-project condition or better.

6. PROTECTION OF EXISTING 16” CITY OF BOULDER HIGH PRESSURE WATER LINES (2EA.)

7. Clearing and grubbing within limits of disturbance.

8. Demolition and removal of existing temporary repair structures.

9. Unclassified excavation in conformity with the lines and grades shown in the construction drawings.
