Where no other procedure is made specifically applicable by another provision of this chapter, any structure, condition or activity prohibited by this chapter may be abated by the City Manager in accordance with the following procedure. The City Manager shall first investigate the existence of the alleged nuisance to determine whether or not a nuisance, as defined in Section 652.01, exists and to further determine the person who has created or is committing or maintaining such nuisance. He or she shall then give written notice to the person responsible for the creation, commission or maintenance of such nuisance, specifying in particular the nature thereof, the corrective action to be taken to abate the same and the time limit for abatement of such nuisance, which shall be a reasonable time, but not to exceed fifteen days from the time the notice is served. Such notice shall be served verbally to such person or in writing. If in writing, it shall be sent certified, return receipt requested. If, at the expiration of the time limit in such notice, the person responsible for the commission, creation or maintenance of the nuisance has not complied with the requirements thereof, the City Manager shall carry out the requirements of such notice. The cost of such abatement shall be a debt owed the City by the person responsible for the commission, creation or maintenance of such nuisance.
