Kingman Crossing Traffic Interchange

Project Limits:

This project is located on Interstate 40 (I-40) between mile posts (MP) MP 54.46 – MP 55.85 in the city of Kingman, Mohave County, Arizona. The Kingman Crossing traffic interchange will be located within the identified project limits.

Project Scope:

The City of Kingman is currently experiencing an increase in residential development, with the largest concentration of growth occurring in east Kingman. The purpose of the project is to provide access and accommodate future traffic volumes generated by the growing east Kingman area and to relieve congestion at the existing East Kingman TI (Andy Devine Avenue/SR 66).

Environmental Planning re-evaluated the environmental impacts of the additions to the scope of work and reduced limits. A cultural consultation and closeout and a Preliminary Initial Site Assessment (PISA) were prepared for the re-evaluation.

The new scope of work consists of:

constructing a new diamond TI 1.5 miles east of the existing East Kingman TI constructing two 2-span girder bridges constructing ramps extending the eastbound and westbound ramps east of the TI extending culverts at nine locations on I-40 constructing 0.33 mile of four-lane arterial roadway constructing a bicycle lane, sidewalk, curb, and gutter constructing a storm drain with manholes and catch basins constructing a temporary and permanent drainage channel constructing temporary two lane crossover relocating signs constructing half barrier, crash cushion, vertical curb, cable barrier, chain-link fence extending left and right lanes

constructing, extending, and regrading median relocating utilities constructing retaining walls backfilling and excavation installing new guardrail saw cutting shoulder placing asphalt concrete, asphaltic rubber-asphaltic concrete friction course, and Portland cement concrete pavement

The project will occur within ADOT ROW and within lands owned by the City of Kingman, Arizona State Land Department (ASLD), and private lands. New right-of-way (ROW) and temporary construction easements (TCE) will be required from private landowners, ASLD, and the City of Kingman for the construction of the new TI, Rancho Santa Fe Parkway and drainage easements.

If there is a change in the project scope or the project limits, Environmental Planning (Taylor Gustafson, (480)349- 8832) must be contacted to evaluate potential impacts.

This constitutes environmental approval.

The following project environmental commitments must be included in the project activities and are not subject to change without written approval from Environmental Planning.

City of Kingman Responsibilities:

• Protected native plants within the project limits will be impacted by this project; therefore, the City of Kingman will determine if Arizona Department of Agriculture notification is needed. If notification is needed, the City of Kingman will notify the Arizona Department of Agriculture at least 60 days prior to the start of construction so that the Arizona Department of Agriculture can determine the disposition of these plants.

• All disturbed soils not paved that will not be landscaped or otherwise permanently stabilized by construction will be seeded using species native to the project vicinity.

• During final design, the City of Kingman project manager will contact the Arizona Department of Transportation Environmental Planning noise coordinator (602.712.8246 or 602.712.7767) to arrange for qualified personnel to review and update the noise analysis.

• The City of Kingman will determine who will prepare the Storm Water Pollution Prevention Plan.

Contractor Responsibilities:

• 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 list 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 City of Kingman for review and approval prior to implementation by the contractor.

Contractor Responsibilities (continued):

• Prior to the start of ground-disturbing activities, the contractor shall arrange for and perform the control of noxious and invasive species in the project area

• The contractor shall submit a Lead-Based Paint Removal and Abatement Plan for the removal of pavement striping within the project limits to the Engineer and the Arizona Department of Transportation Environmental Planning hazardous materials coordinator (602.920.3882 or 602.712.7767) for review and approval at least ten (10) working days prior to paint stripe removal.

• If suspected hazardous materials are encountered during construction, work shall cease at that location and the Engineer will be notified. The Engineer will contact the Arizona Department of Transportation Environmental Planning hazardous materials coordinator (602.920.3882 or 602.712.7767) immediately, and make arrangements for assessment, treatment and disposal of those materials.

• The contractor shall complete a National Standards for Hazardous Air Pollutants (NESHAP) notification for the work associated with extending culverts at 9 locations on I-40 and demolition of the temporary two lane crossover and submit to the Engineer, who shall submit it to the Arizona Department of Transportation environmental planning hazardous material coordinator (602.920.3882 or 602.712.7767) for a five (5) working day review and approval. Upon approval, the contractor shall file the notification with the Arizona Department of Environmental Quality (ADEQ) at least ten (10) working days prior to the commencement of work.

• 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.

• Prior to beginning any work, an approved contractor shall develop and implement a Lead-Based Paint Removal and Abatement Plan for the removal of the lead-based paint, Toxicity Characteristic Leaching Procedure testing of the generated waste stream, and proper disposal of the waste stream derived from the removal of the I-40 WB Off-Ramp Median Curb Paint within the project limits. The contractor shall select a lead abatement contractor that meets the qualification requirements specified within the special provisions and as approval by the Engineer. The contractor shall follow all applicable federal, state, and local codes and regulations, including Arizona Department of Transportation Standard Specifications for Road and Bridge Construction (2021 Edition), related to the treatment and handling of lead-based paint.

The contractor shall submit the Lead-Based Paint Removal and Abatement Plan to the Engineer and the ADOT Environmental Planning Hazardous Materials Coordinator (602.920.3882 or 602.712.7767) for review and approval at least 10 (ten) working days prior to beginning the construction, extension, and regrade of the median.
