Whenever the Commission with the consent of the property owner, certifies property as being a registered landmark, it may seek and obtain from such property owner an agreement as to such restrictions upon the use of the property as the Commission finds are reasonable and are calculated to perpetuate and preserve the features which led it to designate such property as an historical landmark. All such arrangements between the Commission and the property owner shall be in writing, and when duly signed and acknowledged, shall be recorded in the office of the City Clerk and when so recorded shall be notification to the assessor or the restrictions therein set forth.
