The majority of state highways are projected to operate at unacceptable levels due to increase in regional travel demand. A comprehensive study was performed for the travel corridors along State Route 99 and State Route 70 from north of Sacramento to Chico in 1990. The recommendations for improvements are documented in the State Routes 70 and 99 Corridor Study, (July 1990). The following improvements are recommended within the State Route 70 and 99 Corridor Study and the Route Concept Reports.

The following are the improvements identified for the state highway segments in their respective Route Concept Reports (RCR).

State Route 20

No improvements were identified in the RCR. The capacity of the segment could be improved if the non-expressway portion of the segment is converted from a two lane conventional highway to a four lane expressway. This improvement would require widening of the Sutter Causeway.

State Route 70

The State Routes 70 and 99 Corridor Study (July 1990), recommends a four lane freeway facility from State Route 70's Junction with State Route 99 north to the junction with State Route 65 in Yuba County.

State Route 99

Sacramento County line to Junction Route 70: Widening of this segment to a four lane freeway is recommended in the Route Concept Report.

Intersection of Riego Road: Improvement will eventually include construction of a freeway interchange.

Junction Route 70 to Bogue Road: The Route Concept Report has identified the necessity of widening this segment from the junction with State Route 113 to Bogue Road to four lanes. The traffic projections also suggests widening the segment between Junction Route 70 to State Route 113 to a four lane expressway.

Bogue Road to State Route 20: The State Routes 70 and 99 Corridor Study, (July 1990) recommended this segment to be ultimately upgraded to a six lane expressway with an urban interchange at State Route 20.

End of freeway to Live Oak: The State Routes 70 and 99 Corridor Study, (July 1990) recommended this segment to be upgraded to a four lane expressway facility.
The State Route 70 and 99 Corridor Major Investment Study (MIS) was published in June of 1995. This study identifies "pipeline projects" that are viewed as initial investments (or stages) towards realizing the benefits of implementing the State Route 70 and 99 Corridor Study. The MIS is a major investment analysis that evaluates the efficiency and effectiveness of alternative investment strategies in attaining local, state and federal goals and objectives.

Pipelines projects listed within the MIS are considered initial investments (or stages) toward full implementation of the State Route 70 and 99 Corridor Study. The MIS identifies the following as pipeline projects within Sutter County.

* 4-lane freeway for SR 70 from the SR 70/SR 99 split north to the McGowen Parkway in Yuba County.

* 2-lane "Southern Crossing" of the Feather River on the Bogue-Erle Road alignment.

* Interchange at SR 20/SR 99 Intersection in Yuba City.


The State Routes 70/99 Corridor Study was prepared and approved in 1990 by SACOG and the Butte County Association of Governments. The accompanying Draft Implementation Plan identifies the need to make other major improvements in the 70/99 corridor. While these improvements would provide additional access and increase safety for motorists, there is simply not enough money to make all the major improvements called for in the corridor study.

It should be stressed that major future cost savings can be realized by preserving right-of-way corridors for future road improvement projects. Protection of these potential rights-of-way from upzoning can help achieve this objective.


Table 4.11-1 shows the roadway improvements identified to improve the operating conditions of the deficient roadways identified in Tables 4.9-1 and 4.9-2. Many of the improvements identified in Table 4.11-1 are included in the Traffic Impact Fee Study for Sutter County/Yuba City, (May 1993) report. Additional improvements have been identified through the General Plan environmental review process. The environmental review process utilized the most current data and traffic models in conjunction with the preferred land use alternative to identify required improvements. Recommended improvements vary from Caltrans studies in some instances.

Sutter County is currently served by an extensive roadway system that is comprised of primarily rural roadways serving low intensity agricultural land uses. Automobile travel is the primary mode of transportation throughout the County.

Sutter County is a member of the Sacramento Area Council of Governments (SACOG) for which a Regional Transportation Plan (RTP) was prepared in 1992. SACOG includes Sacramento, Yolo, Yuba and Sutter Counties. This RTP addresses the regional transportation needs of these jurisdictions and incorporates a variety of transit modes. The overall goal is to provide transportation services and facilities that will modify existing urban forms, shape future urban forms, and otherwise influence land use change to make the most efficient and effective use of the region's transportation resources.

Fixed route and demand responsive transit services within Sutter County are described below. These services were available as of January, 1996.


Sutter County is served by the Yuba-Sutter Transit fixed route system. This system operates a Yuba City loop route, a Marysville loop, a Yuba City to Yuba College route, and a Yuba College to Olivehurst route. These services are available Monday through Friday from 6:30 a.m. to 6:30 p.m. The service runs every hour and the basic one way fare is one dollar. Senior/Disabled and Youth fares are provided at discount rates and transfers between routes are free.

Yuba Sutter Transit also provides a Sacramento Commuter Express that provides daily peak hour service to downtown Sacramento from Marysville and Yuba City. The Commuter Express offers four morning and four afternoon schedules. Regional Transit (RT) transfers are available at several stops.

Additionally there is a Midday Express service from Yuba City/Marysville to downtown Sacramento and major medical facilities every weekday which runs late morning and early afternoon. This service is provided on a first come first served basis with reservations required.


The transportation needs of the elderly and disabled are provided for by Yuba Sutter Transit Dial-A-Ride. This is a demand responsive bus service that is provided on a first come, first served basis to those eligible for the service. The bus will pick up passengers at any address within the service area and take them to their destination. Persons age 62 and over or disabled are eligible for Dial-A-Ride service automatically. Other persons traveling to or from locations more than half-a-mile from the fixed routes may also be eligible. General public Dial-A-ride passengers are subject to transfer to the fixed route system if they travel across the service area. Transfers between the Dial-A-Ride and fixed route services are free.

This system operates within the Yuba City Urban Area and also serves Marysville, Linda and Olivehurst in Yuba County. The services are available Monday through Friday 6:30 a.m. to 6:30 p.m. and Saturday 9:00 a.m. to 3:00 p.m. No service is available on Sunday.

Yuba Sutter Transit also operates a reservation only route from Live Oak to Yuba City. Reservations must be made by 6:00 p.m. the day before, or the bus will not make the run that day. The service runs one round trip each weekday. The bus will pick up and deliver passengers anywhere within the Live Oak City Limits and anywhere within 1/4 mile of the route in Yuba City and Marysville.


Rail service is available for the transport of agricultural goods and other materials by two railroad companies. The Union Pacific Railroad line runs through south Sutter County east of Highway 70 from Sacramento County to Yuba County. The Southern Pacific Railroad enters Sutter County north of Yuba City and continues northerly to Butte County. (See Figure 4.13-1).

Passenger service is only available in Marysville by way of the AMTRAK Coast Starlight train that runs from Los Angeles to Seattle with one stop daily in each direction. The limited hours of operation make this train service ineffective as a travel alternative for commuters. At the writing of this report, a study entitled the "Northern Sacramento Valley Intercity Passenger Rail Feasibility Study" is being conducted to evaluate opportunities of establishing intercity rail service from Sacramento to Redding. This study proposes the use of the Southern Pacific Railroad line as a commuter line for passenger service.

The Union Pacific line only provides freight service. It is anticipated that this use will continue into the foreseeable future.

No new rail lines are planned within Sutter County. Several railroad corridors have been abandoned in the past few years for various reasons, including high maintenance costs and limited use. The old Sacramento Northern Railroad right-of-way that parallels State Route 20 is scheduled to be abandoned and is proposed for development of a Class I bike/pedestrian path between Yuba City and the community of Sutter.

FIGURE 4.13-1


Air transportation in Sutter County is served by the Sutter County Airport near Yuba City. There are also numerous private airfields and heliports serving general aviation and agricultural users. Significant airport facilities are depicted on Figure 4.13-1 of this report.

State Law requires public access airports to develop Airport Comprehensive Land Use Plans, designating airport vicinity land use and clear zones. Such plans are to be adopted by the County's Airport Land Use Commission (ALUC), which for Sutter County is the Sacramento Area Council of Governments (SACOG).


Sutter County Airport is surrounded to the north, south and west by Yuba City. The airport is located on 170 acres of land, and is operated by the Sutter County Public Works Department. It was established in 1947. The airport's single paved runway is 3,040 feet in length and 75 feet in width. The runway has medium intensity lighting, with a visual approach slope indicator at one end. There are 50 T-hangers, 85 open tie-downs, and 28 transient parking spaces. Services available at the airport include taxi service, flight instruction, aircraft repair, fuel sales, and rentals.

The most recent estimate of annual operations is 58,500. Ninety-two aircraft are currently based at the airport, along with one helicopter. A major portion of airport operations are a result of agricultural aircraft involved in crop dusting activities.


Sacramento International Airport is located directly south of the Sutter County line between Interstate 5 and the Sacramento River. This facility began operations in 1967 and is served by eight major carriers and four commuter lines. There are more than 130 scheduled departures every day to many major U.S. cities and all major California cities.

Currently, the airport has two runways, each 8,600 feet in length and 150 feet in width. Total aircraft operations in 1985, the most recent year noted in the 1994 Comprehensive Land Use Plan (CLUP), was 130,500. The CLUP contains projections of 149,000 and 167,000 aircraft operations for the years 1995 and 2000, respectively.

The 1994 CLUP adopted for Sacramento International Airport discusses planned expansions of facilities. Anticipated projects include improving roadway circulation within the airport and expanding the existing runways from 8,600 feet to 12,000 feet in length. Lengthening the runways will allow larger commercial airliners to utilize the airport and expand the service status of the facility to an International Airport. Figure 9 of the CLUP identifies a large area on the eastern perimeter of the existing airport as Metro Air Park Special Planning Area. However, this area is not discussed within the CLUP.

Extension of the existing runways will have a potentially significant impact on Sutter County. Lengthening the runways will extend the Approach/Departure Zone of the airport well into Sutter County. Land uses within Approach/Departure Zones are highly restricted, with agriculture and mining operations, cemeteries and natural reserves allowed under limited conditions.

Other Airport Facilities

Airport facilities are regulated by the California Department of Transportation Aeronautics Program. The Aeronautics Program issues permits for Public Use Airports, such as Sutter County Airport, and Special Use Airports. Special Use Airports in Sutter County include Wagner, Riego and Tenco Tractor facilities.

Two other types of airports, Personal Use and Agricultural, are not regulated and require no permit to operate. Personal Use Airports are facilities that serve only a single owner and, on occasion, visiting flights. Airports serving only agricultural uses are exempt from permits even though they may have high levels of aircraft operations (some in excess of 10,000 operations annually). Agricultural airports with high activity levels are depicted on Figure 4.13-1 of this report.


A major regional improvement plan affecting Sutter County is the proposed improvement of the State Route 70 corridor to freeway standards. This plan is part of SACOG's 1992 Regional Transportation Plan (RTP) and would include a connecting roadway between Highway 99 in Sutter County and Highway 70 in Yuba County.

The 1995 Major Investment Study (MIS) prepared by Caltrans is intended to commence implementation of the State Route 70 and 99 Corridor Study. Within the MIS are several projects within Yuba County to improve traffic conditions on SR 70 around Marysville.


* Sutter County is served by Highway 99 from Butte County in the north to Sacramento County in the south which includes a five mile section of freeway north of Yuba City.

* Sutter County is bordered by major rivers which limit roadway connections and alignments. The Sutter Bypass and various railroad alignments also restrict roadway connections within the County as well as access to the surrounding region.

* Regional travel north-south through Sutter County is limited to State Routes 70, 99 and 113. East-west travel is confined to State Route 20. A system of County roads with varying capacities interconnect this regional system.

* Sutter County has identified Level of Service (LOS) "D" as the minimum acceptable standard. There are no roadways within Sutter County that are operating beyond capacity. Numerous segments of State Route 99 have been identified as operating at or near capacity.

* The primary regional improvement plan involving Sutter County is the proposed improvement of the State Route 70 corridor to freeway standards to connect Sacramento and Chico. The construction of a third bridge connecting Yuba City and Marysville is another regional improvement project of high priority.

* Highway 99 functions as the main north/south corridor through Sutter County. This roadway is of critical importance since it accommodates large volumes of truck traffic and also connects Sutter County, Butte County and Chico to the Sacramento Metropolitan Area.

* According to projected travel demands, numerous State Routes and County roadways will exceed LOS "D" and will exceed design capacity by the year 2015. These identified roadways and intersections will require specific improvements in order to maintain the LOS at an acceptable level.

* Sutter County is currently served by the Yuba-Sutter Transit fixed route transit service that provides broad local coverage as well as commuter service to Sacramento. There is also a local demand responsive service for elderly and disabled residents.

* Sutter County currently has two railroad lines crossing portions of the County that can provide transport of agricultural goods and other materials. Limited passenger service is currently available in Marysville on the Southern Pacific line, however, this line is being proposed for commuter service in the future. No new rail lines are planned and several have been abandoned in the past.

* Air transportation is provided to the public by the Sutter County Airport. There are several small private airports that serve agricultural purposes and private uses. Regional air transportation services are provided by the Sacramento International Airport in Sacramento County.

* There is an identified corridor for State Route 99 that includes a City of Live Oak bypass.

* There are a number of proposed improvements to the regional travel system that will require additional right-of-way. Right-of-way acquisition costs can be reduced by preserving these right-of-ways from up-zoning and development.

* It is in the best interest of Sutter County that all local jurisdictions and transportation agencies work together on an ongoing basis to address regional transportation issues.

* Existing bikeway facilities within Sutter County are limited. Full implementation of the Yuba- Sutter Bikeway Master Plan could result in the addition of 210.10 miles (338.10 kilometers) of bikeway facilities within Sutter County.
