The Planning Commission shall, after at least ten days’ prior notice duly given, hold a public hearing on each conditional use permit application, and shall hear all persons interested in such application, and may continue the hearing for the taking of additional evidence. At the conclusion of the hearing, the Planning Commission shall grant, conditionally grant, or deny such application, in whole or in part, but shall not grant any application with reference to any structure, land or premises not described in the application. The Planning Commission shall not grant any application unless it has found that the requested use will not, under the particular circumstances, be detrimental to the health, safety, morals, comfort, convenience and general welfare of the persons residing or working in the neighborhood of such proposed use, and will not be injurious or detrimental to the property and improvements in the neighborhood of such proposed use, or to the general welfare of the City. In imposing conditions on conditional use permits, the Planning Commission may consider, among other criteria, design review standards as set forth in Title 20 of this Code. A conditional use permit shall not become effective until the expiration of the period within which appeals may be filed pursuant to Section 19.80.040. (Ord. 89-1 § 1, 1989.)
