Land devoted primarily to agricultural, timber, or livestock uses and being used for the commercial production of agricultural, timber, or livestock products may be included in a community facilities district only if such land is contiguous to other land which is included within the described exterior boundaries of the community facilities district, and only if the legislative body finds that the land will be benefited by any of the types of public facilities and services proposed to be provided within the district. The land may, however, be included in the community facilities district, if the owner requests its inclusion.
