Specifications include, but are not limited to: - Property owners within the City are required by City Ordinance to maintain lawns and grounds to acceptable levels. In the event that the owner is either unwilling to cooperate or unable to be located, the City will authorize and pay for the maintenance of the property as authorized by Ordinance 3105. The cost incurred by the City for this service will become a lien on the property. Due to the length of time since they were last maintained, lawn maintenance may consist of bush-hogging, finish mowing, trimming or any combination thereof as directed by the City of Columbia Codes Department. The frequency with which complaints will be filed is unpredictable; therefore, the City will not guarantee the amount of work that may be required under any resulting agreement.
