Chapter 21.89 — TRUCK PARKING FACILITIES

The purpose of this chapter is to provide land use regulations for the parking of tractor-trailer combinations which are not incidental and accessory to the agricultural use of the property and do not qualify to operate as an agricultural service establishment.

These regulations are intended to allow for the limited parking of tractor-trailer combinations while minimizing impacts on agricultural land and avoiding the creation of a concentration of commercial and industrial uses in the vicinity. The allowance for non-agriculturally related truck parking in the A-2 (General Agriculture) zoning district recognizes a shortage in truck parking options that impact roadway driver safety and community character, when trucks must park on the side of the road. Limitations on the life of a use permit issued under this chapter for truck parking recognizes the use is transitional in nature and ongoing parking outside of commercial and industrial zoning districts is intended to be short term with limited improvements that will not impact the ongoing agricultural use of the property on which the use is located or the surrounding properties. (Ord. CS 1401, 11/18/2025)

The regulations set forth in this chapter shall apply in the General Agriculture (A-2) zoning district. (Ord. CS 1401, 11/18/2025)

"Tractor-trailer combination" means a tractor-trailer, truck/trailer-trailer, or truck/tanker trailer combination with a minimum of five axles and capable of hauling a combined gross vehicle weight (GVW) of eighty thousand pounds. The following illustrates the type of permitted combinations:

"Truck parking" means the parking of any tractor-trailer combination.

"Truck parking facility" means a property used for the parking of more than one tractor-trailer combination.

Parking of tractor-trailer combinations may be allowed subject to first securing a use permit, when the planning commission finds that, in addition to the findings required under Section 21.96.050 :

• A. The establishment as proposed will not be substantially detrimental to or in conflict with agricultural use of other property in the vicinity;

• B. The establishment as proposed will not create a concentration of truck parking facilities in the vicinity, as defined in Section 21.89.040.C.3; and

• C. All the following standards and requirements are met:

  1. The parcel on which truck parking will occur is at least one gross acre in size and less than ten gross acres in size and is not enrolled in a Williamson Act Contract.

  2. The total number of tractors, truck/trailers and truck/tankers shall not exceed twelve and the total number of trailers shall not exceed two per tractor, truck/trailer, or truck/tanker. For the purpose of this chapter, a set of double trailers shall be equivalent to one trailer.

  3. Concentration. For the purposes of this section, a concentration shall be deemed to occur when the number of truck parking facilities within the designated area exceeds the limits set forth in the following criteria:

     • a. In determining concentration, all truck parking facilities located in an A-2, or a P-D zoning district where truck parking is the principal use, shall be considered, with the exception of the following:

       • i. Truck parking which is incidental or accessory to an agricultural operation or permitted by use permit as a Tier One or Tier Two use in the A-2 zoning district;

       • ii. Truck parking which is permitted as a home occupation with a valid business license issued by the county treasurer-tax collector;

       • iii. Truck parking which has been established in violation of this title;

       • iv. Truck parking which is located both within the boundaries of an adopted community plan.

     • b. For areas within a one-mile distance from the edge of a right-of-way of a designated interstate or state route, a concentration is considered any situation where there are more than two truck parking facilities (or portion thereof) within a one-mile radius of any property. A property's distance to an interstate or state route is determined based on the location of the driveway apron serving a permitted truck parking facility.

     • c. For areas a distance of more than one-mile from the edge of a right-of-way of a designated interstate or state route, a concentration is considered any situation where there is more than one truck parking facility (or portion thereof) within a one-mile radius of any property; however, where a second existing facility is located within a one-mile distance from a designated interstate or state route, there may be up to two truck parking facilities. A property's distance to an interstate or state route is determined based on the location of the driveway apron serving a permitted truck parking facility.

cility (or portion thereof) within a one-mile radius of any property; however, where a second existing facility is located within a one-mile distance from a designated interstate or state route, there may be up to two truck parking facilities. A property's distance to an interstate or state route is determined based on the location of the driveway apron serving a permitted truck parking facility.

  - d. Exception. A higher concentration of truck parking facilities may be allowed if the planning commission or board of supervisors determine that the facilities are sufficiently separated by a physical feature (e.g., river, canal, railroad, highway etc.) which precludes trucks accessing the facilities from consistently traveling the same roadways. 

  - e. Designated interstates and state routes shall be considered the following: 

     - i. Interstate 5; 

     - ii. State Route 33; 

     - iii. State Route 99; 

iv. State Route 108;

The area where a detached office is located shall be evaluated in the total area allowed for the parking facility.

  8. On-site restrooms accessible to drivers and employees shall be maintained on-site. Portable restrooms may be allowed unless fixed permanent restrooms are required by the California Plumbing Code.
