• If vegetation clearing will occur during the migratory bird breeding season (March 1– August 31), the contractor shall avoid any active bird nests. If the active nests cannot be avoided, the contractor shall notify the Engineer to evaluate the situation. During the non-breeding season (September 1–February 28) vegetation removal is not subject to this restriction.

• Prior to construction, all personnel who will be on-site, including, but not limited to, contractors, Contractors’ employees, supervisors, inspectors, and subcontractors shall review the attached Arizona Department of Transportation Environmental Planning “Western Burrowing Owl Awareness” flyer (See Appendix E).

• If any burrowing owls or active burrows are identified the contractor shall notify the Engineer immediately. No construction activities shall take place within 100 feet of any active burrow.

• If the Engineer in cooperation with the Environmental Planning Biologist determines that burrowing owls cannot be avoided, the contractor shall employ a qualified biologist holding a permit from the US Fish & Wildlife Service to relocate burrowing owls from the project area, as appropriate.

• The contractor shall develop a Noxious and Invasive Plant Species Treatment and Control Plan in accordance with the requirements in the contract documents. Plants to be controlled shall include those listed in the state and federal noxious weed and the state invasive species lists in accordance with state and federal laws and executive orders. The plan and associated treatments shall include all areas within the project right-of-way and easements as shown on the project plans. The treatment and control plan shall be submitted to the Engineer for the Department of Transportation and Mobility Professional Landscape Architect for review and approval prior to implementation by the contractor.

• Prior to the start of ground-disturbing activities and throughout the duration of construction and any landscape establishment period, the contractor shall arrange for and perform the control of noxious and invasive species in the project area.

• For milling activities, the roadway surface preceding the milling machine shall be kept sufficiently wet so as to prevent the generation of any visible fugitive dust particles, but not so wet as to cause excess runoff from the roadway surface onto the roadway shoulder.

• The contractor shall not utilize any abrasive tools or methods for the removal of the light poles that would disturb the lead-based paint. This includes, but is not limited to, sawing, grinding, sanding, or heating. Woven straps or other non-abrasive items (not linked chains) may be used to lift the light poles from their base.
