A decision as to the meaning, application or intent of any development regulation as it relates to a specific piece of property may be requested by an applicant, staff, or a citizen at any time prior to a final decision on a project permit application to which the development regulation may be applied. The request shall be on a form provided by the director and include identification of the regulation in question, a description of the property and a clear statement of the issue or question to be decided. The director shall issue a written interpretation within a reasonable time. Within 30 calendar days after receipt of the completed form, the director shall issue a written interpretation, or if additional time is needed due to the level of complexity of the issue or issues raised in the request, the director shall provide written notification that up to an additional 30 calendar days are required. When the interpretation is issued, a copy shall be filed in a book or binder for such interpretations, readily available to the public at the appropriate department’s service counter.
