September 16, 2026 Page 6 of 48

10. ADA DURING CONSTRUCTION

The needs and control of all road users (motorists, bicyclists, and pedestrians within the highway and/or public right-of-way, including persons with disabilities in accordance with the Americans with Disabilities Act of 1990 (ADA), Title II, Paragraph 35.130) through a temporary traffic control “TTC” zone shall be an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents. The primary function of TTC is to provide for the reasonably safe and efficient movement of road users through or around TTC zones while reasonably protecting workers, responders to traffic incidents, and equipment.

Temporary facilities, including reasonably safe pedestrian routes around work sites, are also covered by the accessibility requirements of the Americans with Disabilities Act of 1990 (ADA) (Public Law 101-336, 104 Stat.327, July 26, 1990. 42 USC 12101-12213 (as amended)). Implementation of TTC plans and installation and maintenance of devices shall be the responsibility of the Contractor performing the construction, alteration and/or maintenance of the highway or public right-of-way.

When an existing continuous sidewalk or street crossing route cannot be maintained for pedestrians because of construction, either temporary walkways with curb ramps are to be provided, or the construction shall be phased to maintain access to the affected addresses. Contractors shall be allowed flexibility as long as the requirements are met.

The location of the construction project and whether or not accessible facilities are present shall also determine the extent of the temporary facilities needed. The Contractor is only required to maintain practical continuity where accessible facilities already exist. On low speed rural roads that do not have sidewalks and are used by cyclists, no additional measures are needed as the bicycles can share the available travel lanes with other traffic. On moderate to higher speed rural roads, if a bike lane exists then it should be properly detoured, complete with signage, to provide a safe route through or around the work area. If a road or bridge project affects vehicular traffic to a business, residence, school or any other type of pedestrian generating location with existing accessible facilities, then pedestrian and handicapped access must be maintained.

A continuous route for all pedestrians, including the disabled and bicyclists, shall be maintained at all times. When existing pedestrian facilities are disrupted, closed, or relocated in a TTC zone, the temporary facilities shall be detectable and include accessibility features consistent with the features present in the existing pedestrian facility. The temporary route should enable pedestrians to bypass the construction site while minimizing the retracing of their steps or going significantly out of their way. Additional consideration must be given to the disabled since they may not have the physical or cognitive ability to improvise (e.g. balancing along the curb or a very narrow path) or use unofficial alternatives (e.g. using an adjacent grass surface). Temporary routes must meet the accessibility guidelines of the ADA for permanent facilities and shall be marked with the proper signage. Should existing crosswalks at signalized intersections be closed or made inaccessible, temporary crosswalks should be painted in an accessible location. Temporary signals should include pedestrian phases.

Contractors shall not block temporary walkways with Contractor parking, materials piles, signs, rubble or rubbish. Construction equipment and equipment operation must be separated from the temporary walkways. At work zones where higher volumes of pedestrian traffic or school children exist, pedestrian fences or other protective barriers may be needed to prevent access into the construction area.

September 16, 2026 Page 7 of 48

11. ACCESS DURING CONSTRUCTION

Access to adjacent properties shall be maintained at all times. This shall include providing an adequate surface (free of protruding rocks, holes and mud) for all emergency vehicles and pedestrians. The cost to maintain access shall be considered incidental to other items of work and no separate payment will be made.

12. PROTECTION OF TREES & BUSHES

The Contractor shall be responsible for protecting the existing trees not called out for removal within the project area and must use practicable care in the protection of trees, tree branches and tree roots within the construction limits. Excavation for the proposed improvements shall be carried out in a way that avoids root damage as much as practicable. This may require handwork, which shall be considered incidental to other items of work, and no separate payment will be made.

Protect all trees in place, unless otherwise approved. Tree pruning and root pruning shall be performed by a certified arborist.

Damage Clause – Damage to trees or bushes during construction will be assessed against Contractor per dollar amount of replacement value. The value and damage amount will be determined by ratings of the International Society of Arboriculture Shade Tree Evaluation, Latest Edition, as facilitated by Boise Parks & Recreation Urban Forestry Division.

Furnish all work, services, materials, and related items only as necessary to complete the work indicated in the specifications, plans and details.

Protection of Existing Irrigation Systems - Contractor shall protect and maintain the operation of all existing irrigation systems. All portions of the irrigation system must be functional and the system operable at the end of each workday. No portion of the irrigation system may be shut down or out of use for longer than 24 hours. All damage to the existing system must be repaired within 24 hours.

13. COORDINATION WITH UTILITIES

It shall be the Contractor’s responsibility to contact and coordinate with the various utility companies as necessary for the successful completion of the project. This coordination effort shall include, but not be limited to, working other than normal operation hours to permit the relocation of utilities and construction of the roadway within the time frame of this contract. The cost to contact and coordinate with utilities shall be considered incidental to other items of work and no separate payment will be made.

Utility information is shown only for surface features, and if provided by the owner of the utility for non-surface features. The information shown is for reference purposes only and does not necessarily represent actual field conditions. The Engineer assumes no liability for the accuracy of the information shown, or conflicts due to inaccurate or incomplete utility information. The Contractor shall call Dig Line a minimum of 48 hours prior to any excavation to request utility locations at 1-800-342-1585.

The Contractor shall expose all existing utility crossings to verify locations and elevations prior to any other construction that may affect those utilities. The cost associated with exposing the existing utilities is considered incidental to the project and no separate payment will be made.
