I . 'Widening of State Route 99 north of Arch Road to eight lanes; and Widening of State Route 99 between Arch Road and French Camp Road to six lanes. At the point when the airport passenger service exceeds two million passengers, the terminal will be i relocated and the flyover ramps will be constructed. The General Plan standard for Level of Service (LOS) is"D"for the Stockton planning area. Through the 2015 project, all intersections operate at LOS D or better with the improvements identified in the KASL report. Although the impacts for the project are less than significant, a mitigation measure is recommended for both interchange Phase I and Phase li (flyover ramps) to continue monitoring and evaluating traffic operating conditions at critical roadways and intersections and to implement measures to ensure that operating conditions remain at LOS D or better. In the cumulative analysis,the maximum feasible level of improvements are planned, and all study area ' intersections can be mitigated to LOS D or better, except Arch-Airport Road and "B" Street, and Airport Way and Eighth Street, which is almost two miles north of the project. Both of these intersections and V/C = 0.92, which is within two percent of V/C = 0.90, which would be LOS D. The cumulative analysis included going from 2 million to 4 million enplanements per year, an additional 40 acres of commercial/industrial development at the airport, buildout of the City of Stockton General Plan, and the development of a major theme park in Lathrop. An updated traffic analysis by Rajappan & Meyer, in conjunction with the State Route 99 and Arch Road G interchange, assumed 85 percent buildout of the City of Stockton General Plan. Their analysis, which includes this project, indicated that all intersections within their study area operated at LOS D or better t 6 ' through 2024,which is five years beyond the planning period for the airport project. Because of the extremely conservative nature of the assumptions built into the cumulative analysis for the airport project, it can be reasonably concluded that the cumulative impacts can be mitigated to LOS D or better_ It is also important to note that the airport currently has urban zoning classifications, and what is being proposed is modification of these classifications to permit more flexibility in siting aviation related and compatible uses. The County acknowledges that many of the roadway improvements assumed to be in place during the planning period for the airport are currently unfunded. The specific analysis for these improvements is beyond the scope of the airport project and its EER. However, the County fully intends to participate in the evaluation and monitoring of traffic operating conditions at critical intersections. The Airport/County, developers, and/or successors-in-interest will participate in their proportionate share of the cost for appropriate mitigation measures to ensure that. operating conditions remain at LOS D or better as development occurs. Further, the County acknowledges that funding mechanisms for major roadway improvements in the area, including but not limited to the Arch-Sperry corridor, are urgently needed, and I the County is committed to establishing such funding mechanisms jointly with the City of Stockton and Caltrans. Air Quality Both the State of California and the federal government have established ambient air quality standards for several pollutants. The pollutants of concern in San Joaquin County include carbon monoxide, ozone, and inhaled particulate matter (PM-10). The State standard for carbon monoxide (CO) is 20 parts per million (ppm) for one hour and 9 pprn for the eight-hour averaging period.
