Chapter 3 Comments and Coordination disporportionately high and adverse impacts are not practicable. In determining whether a mitigation measure or an alternative is “practicable,” the social, economic (including costs) and environmental impacts of avoiding or mitigating the adverse impacts would be taken into account (USDOT1998). 2.1.10 Traffic and Transportation/Pedestrian & Bicycle Facilities Regulatory Setting The Department, as assigned by the Federal Highway Administration, directs that full consideration should be given to the safe accommodation of pedestrians and cyclists during the development of federal-aid highway projects (see 23 Code of Federal Regulations 652). It further directs that the special needs of the elderly and the disabled must be considered in all federal-aid projects that include pedestrian facilities. When current or anticipated pedestrian and/or bicycle traffic presents a potential conflict with motor vehicle traffic, every effort must be made to minimize the detrimental impacts on all highway users who share the facility. The Department is committed to carrying out the 1990 Americans with Disabilities Act by building transportation facilities that provide equal access for all persons. The same degree of convenience, accessibility, and safety available to the general public will be provided to persons with disabilities. Affected Environment U.S. 101 is part of the National Highway System (NHS) and serves as an Interstate/Interregional/Intra-regional and commute travel route. The roadway portion in Ventura County is classified as an expressway and the Santa Barbara portion is classified as a freeway. According to the City of Carpinteria General Plan and Local Coastal Plan, the automobile is the primary form of travel for local residents. Circulation throughout the study area is provided primarily via U.S. 101, although State Route (SR) 150 provides another (longer) option to connect to Ventura County. U.S. 101 is a major north-south transportation corridor heavily used by daily commuters. It is known as the Ventura Freeway for a portion of this route within the study area, and it parallels the Pacific Ocean and merges with State Route 1 for 54 miles. It has been designated by the Department as an eligible state scenic highway (CSHMS, 2007). U.S. 101 serves as the principal intercity arterial highway connecting cities between Los Angeles and San Francisco and within the study area, serves as the primary link between Santa Barbara and Ventura Counties. In addition to traversing two counties, the segment of U.S. 101 within the study area passes the 64 IS/EA VEN-SB US101 HOV Project
Chapter 3 Comments and Coordination communities of Mussel Shoals, La Conchita, and Rincon Point, as well as the southern area of the City of Carpinteria. The Ventura/Santa Barbara 101 HOV Traffic study was used to determine the operational benefits of the proposed improvements during peak traffic volume conditions on the highway, while also considering the traffic conditions at the interchange intersections. Furthermore, this study will analyze the impacts to motorists from Mussel Shoals and La Conchita as a result of proposed median closures. To quantify such impact, it is more appropriate to use peak hour turning movement data for these locations. As such, we determined that mainline traffic volumes should be based on the peak hours of U.S. 101, and interchange traffic volumes should be based on the peak hours of the interchanges. This approach will result in a conservative data set and ensures that the peak traffic conditions for the two study components are evaluated accurately. Forecasted Traffic Volumes The Department’s policy is to maintain freeway mainline and ramp operations at LOS based on the Guide for the Preparation of Traffic Impact Studies (The Department’s, December 2002). The project study area is experiencing an average traffic growth rate of 1.05% to 1.30% annually and long distance commuters are increasing, as affordable housing is located further away from business and employment centers. The Santa Barbara County Association of Governments (SBCAG) regional travel model was used to develop annualized growth rates on the U.S. 101 mainline and ramps. Based on total daily traffic forecasts for Year 2005 and Year 2030, a 1.8 percent annually compounded growth rate was used to develop traffic forecasts for the Year 2015 (representing the project opening year) and Year 2035. This growth rate was applied to Year 2008 traffic counts. Intersections/Ramp Operation Peak period intersection counts were conducted during the morning (7:00 to 9:00AM) and evening (4:00 to 6:00PM) at the nine study intersections during a typical weekday (Tuesday through Thursday) in April 2008. The data includes peak hour intersection turning movements and cyclist and pedestrian volumes. The count data indicates that the AM and PM peak hours vary among locations, further justifying the need to use sitespecific peak hour volumes at the intersections. During field reconnaissance, lane configurations, turning movement pocket lengths, and speed limits were collected. The peak hour volumes presented in this report reflect minor IS/EA VEN-SB US101 HOV Project 65
