Any reclamation, levee, irrigation, drainage or other district whatever, or any city, county, or political subdivision may make any contract, expend any of its money, or do anything which its governing body determines will directly or indirectly retire, reduce or remove from any of the land owned by it or held in trust for it by any county treasurer or other public officer, the lien of the Sutter-Butte By-pass Assessment No. 6 of the Sacramento and San Joaquin Drainage District, or will make it possible for the Reclamation Board to order the release of the lien of and abandon any part of said assessment. The trustees of a reclamation district or a county treasurer or other public officer acting as trustee for a reclamation district or other district shall have the right to expend funds of the district, including rentals collected and moneys received by the trustees of the district from lease of or for use or occupation of any land referred to in Sections 51750 to 51757, inclusive, of this code, in such amounts that may be necessary for any of the purposes mentioned in this section.
