When any Historic Landmarks Commission establishes an historic district, it shall notify the County Assessor of the fact of such establishment and the boundaries of the district, together with the restrictions which are applicable to the properties located in such district which have been mutually agreed upon by such Commission and the owners of property within such district. The agreement shall be recorded in the same manner as the recordation of agreements between the Commission and owners of designated landmarks entered into pursuant to the provisions of Section 149.04. The County Assessor shall take such factors into consideration in assessing the properties therein.
