Will stormwater runoff be controlled and where will the water go? Per the SWPPP, whenever possible, runoff is allowed to follow its natural courses and collect in retention basins which will be located throughout the freeway corridor.
Federal law requires providing access to the freeway from the Gila River Indian Community. The Gila River Indian Community will be responsible for connecting to the traffic interchanges, in coordination with appropriate jurisdictions. As documented in the Final Environmental Impact Statement, no feasible and prudent alternative s could be identified to avoid impacts on the park. Approximately one mile of the freeway will pass through the southwestern edge of the park.
The amount of land in the park that will be affected by the freeway is Will local wells and lakes be affected? The freeway will not directly impact the wells or pumps in the Lakewood Community. The pipes that deliver the water from the wells to the lakes will be placed in steel sleeves so they can remain under the freeway. ADOT and the developer have been in close coordination with the Foothills Community Association regarding their community well, which is within the freeway right of way.
The developer team has designed the 24th street exit ramp to avoid the Foothills well. Planning and Environmental Study How was it decided to build this freeway? The freeway was also part of the Regional Transportation Plan funding passed by Maricopa County voters in through Proposition How was the route for the freeway decided? The route for the freeway was determined through a multidisciplinary process to identify a range of reasonable alternatives that were studied in detail in the Environmental Impact Statement EIS.
The study process involved identifying, comparatively screening, and eliminating alternatives based on: As a corridor that is part of a comprehensive regional plan developed by MAG, ADOT serves as the agency responsible for implementation of the plan, with FHWA providing the federal oversight required to access federal funds. FHWA is the lead federal agency responsible for implementing the requirements of the National Environmental Policy Act NEPA , the governing federal law, and was responsible for the ultimate decision in selecting a route for the freeway.
How was public input from the environmental study used? The interests and needs of the public, along with all other social, economic and environmental issues and impacts, were fully analyzed during the study phase of the project. Why not consider light rail or other transit instead of a freeway?
The study did consider a variety of transportation alternatives, modes, and strategies that would fit into the Regional Transportation Plan, including transit. The freeway option was determined to best meet the purpose and need for the project, following an extensive screening process which included evaluation of additional benefits such as system linkage, regional mobility, and consistency with regional and local long-range plans.
While efforts to study alternatives on Community land were attempted, the Community has long held a position of not allowing the freeway to be located on its land. Therefore, the freeway cannot be located on Community land. What impact will the freeway have on air quality? Air quality impacts were estimated through sophisticated computer modeling based on predictions of the amount and nature of traffic under worst-case scenarios.
The emissions models are based on extensive emissions testing that the U. Environmental Protection Agency EPA has conducted on thousands of vehicles representative of the ages and models of the vehicle fleet on the roads today. The carbon monoxide and particulate matter PM10 analyses demonstrated that the freeway will not contribute to any new localized violations, increase the frequency or severity of any existing violation, or delay timely attainment of the National Ambient Air Quality Standards or any required interim emissions reductions or other milestones.
Since ozone is a regional pollutant, there is no requirement to analyze potential impacts and no possibility of localized violations of ozone to occur at the project level. The Maricopa Association of Governments is responsible for developing plans to reduce emissions of ozone precursors in the Maricopa area. In addition, beginning in , the new EPA Tier 3 vehicle and fuel standards will reduce tailpipe and evaporative emissions and reduce mobile source air toxics.
