Temporary Use Permit Established for land uses that would not be appropriate on a permanent basis at a specific location. It regulates short-term activities to prevent or mitigate any effects the uses may have on the surrounding area. Examples of such uses are fairs, festivals, charitable activities, and special events. The time limits are no more than six weekends or seven days during any one year period.
Required for Application:
For the processing of a Temporary Use Permit application, refer to the Introductory Procedures listed on page 3.
For permit approval, the Director must first determine that the application is complete. In addition, he shall also find that adequate parking is available for the proposed special event, and that the use will not exceed the maximum time period such temporary use may be authorized during any 12 month period.
In approving an application, the Director may set forth conditions on land use and related parking in order for the request to be in accord with the findings required by the Burden of Proof and Section 22.56.1880 of the Los Angeles County Code Book, Title 22.
A public hearing may be required depending on the controversial nature of the land use, and the time-frame requested. The Department of Regional Planning does not decide on land uses in county parklands; these are handled by the County Department of Parks and Recreation.
