Immediately after the effective date of this Ordinance or any amendments thereto, the City should prepare a record of nonconforming uses and occupations of lands, buildings, and structures, including tents and trailer coaches, existing at the time of such Ordinance or amendment. Such record should contain the names and addresses of the owners of such nonconforming use and of any occupant, other than the owner, the legal description of the land and the nature and extent of use. This is not meant to be an exhaustive list of all nonconformities in the City, but only those of which the Commission is aware. The Commission should review the record and make such recommendations to the Council as it deems advisable with reference to these nonconforming uses. The record of nonconforming uses and recommendations of the Commission should be filed in the office of the Clerk of Council and record should constitute prima facie evidence of the number, character, and extent of the nonconformities at the time this Ordinance or any amendment thereto becomes effective. The record of nonconforming uses should be reviewed and revised annually as the Commission shall prescribe.
