This law allows county boards of supervisors in California to impose a special tax to promote immigration and boost trade and commerce in their county. The money collected can be used for advertising the county's resources, showcasing its agricultural and industrial benefits, planning fairs or expos, and collaborating with other organizations. Additionally, the board can use funds from the general fund for these purposes, as long as they come from specific revenue sources outlined in other tax laws.

If the special tax under Section 26100 doesn't bring in at least $50,000 in a year, the county board can use general county funds to cover the shortfall up to $50,000.

This section explains that the tax mentioned in this chapter can be added on top of any other tax that's already allowed for fair-related purposes.

This law allows a county board to use funds to provide music and musical performances. These performances can be used inside or outside the county to promote and highlight the county's resources and name. The board can hire musicians, orchestras, bands, or other groups, and they have the option to do this with or without competitive bidding.

This law allows the board of supervisors in a county to set up a group that advises and helps with promoting the county's resources. This group can be called the county board of trade, chamber of commerce, or any other name decided by the board. The group includes representatives from each supervisorial district, appointed by the board. The board decides how many people will be in the group, but all districts must have an equal number of representatives, and no more than two people can represent each district.

This section requires the board of supervisors to establish rules for how the board of trade or chamber of commerce should operate. However, these rules must not conflict with existing laws or take away powers legally given to any county officer.

This law says that under the board of supervisors’ guidance, the county board of trade or chamber of commerce should promote the county’s agricultural, mineral, manufacturing, and other resources. They may also be directed to gather and display county products and industries at exhibits or expositions, whether they're held domestically or abroad.

This law allows the board of supervisors to hire a secretary for the county board of trade or chamber of commerce. They can also set this secretary's salary, which will be paid from the county's advertising fund, just like how other county officials get paid.

This law allows the county board of supervisors to cover travel expenses for members of a county board of trade or chamber of commerce. These expenses are limited to travel within California.

This law allows a county's board of supervisors to create rules for selling advertising spaces on county-owned property to generate revenue.

This law allows county boards in California to use county property for commercial purposes, such as licensing the use of county logos or names, as long as they develop a proper marketing plan. The plan should have clear revenue goals and include methods for evaluating contracts. Counties must consult a licensing agent and review the marketing plan annually. Agreements involving these commercial uses must be approved in a public hearing. However, counties cannot allow their logos to be used in ways that could lead to impersonating officials or safety employees. Also, no one is guaranteed the right to have a marketing agreement with a county.
