Limit operations as follows:

All work shall be completed by November 7, 2016.

General Limitations

A Notice to Proceed must be issued before commencement of any work.

o No on-site work may occur before March 1, 2016.

o It is the government’s intent to issue a Notice to Proceed prior to March 2016 to allow the contractor to work on required submittals.

Restrict all work activities within the right-of-way areas shown in plans.

Asphalt concrete pavement mix design must be approved before pulverizing activities commence.

Night work is not allowed.

Environmental Limitations

Clearing of vegetation on BLM property between stations 350+00 and 456+00; 575+00 and 596+00; and 620+00 and 676+00 should occur before March 15. If vegetation clearing occurs on or after March 15, furnish a qualified biologist as defined in 623.04A to perform surveys of the area for nesting migratory birds. Pre-construction surveys shall be conducted two weeks prior to construction activities. The biologist will conduct a wandering pedestrian survey within 100 feet of the existing area of road disturbance for nesting migratory birds including raptors. If an active nest is identified, a no-disturbance buffer shall be established around the nest. For non-raptors a buffer of up to 50 feet may be established and for raptors a buffer of up to 250 feet may be established. The extent of the buffer shall be determined by a wildlife biologist in consultation with FHWA- CFLHD environment staff or a BLM biologist. No work shall occur within these buffer areas and they shall be maintained and kept in working order until the nest is no longer active as determined by a qualified biologist. A qualified biologist shall be present during construction to monitor the nest(s) and may stop construction if it is determined that the construction activities are resulting in disturbance to the nest.

Do not perform construction activities prior to May 1 or after November 1 between stations 230+00 and 445+00 when large concentrations (greater than 25 individuals) of mule deer are within one-quarter mile of the project area. Minor activities, excluding paving, earthwork, and use of loud equipment, may be permitted upon prior approval of the CO while a large concentration of deer is present.

No construction activities on the LA Aquaduct bridge shall occur prior to August 15th.

Construction activities may commence between August 1st and August 14th if an FHWA approved biologist has determined no active nests are present.

Protect environmentally sensitive or significant features as described below:
