Sec. 20.536.060 - Permits for Approval of Emergency Work.

(A) Purpose. This section describes procedures for processing applications for permits to perform work to resolve problems resulting from a situation falling within the definition of "emergency" in Section 20.308.040(B). In cases of a verified emergency, temporary emergency authorization to proceed with remedial measures may be given by the Director or his or her designee until such time as a coastal development permit application is filed.

(B) Immediate Action Required. When immediate action by a person or public agency performing a public service is required to protect life and public property from imminent danger, or to restore, repair, or maintain public works, utilities, or services destroyed, damaged, or interrupted by natural disaster, serious accident, or in other cases of emergency, the requirements of obtaining any permit under this Chapter may be waived upon notification of the Director of the type and location of the work within seven (7) days of the disaster or discovery of the danger, whichever occurs first. Nothing in this section authorizes permanent erection of structures valued at more than twenty-five thousand dollars ($25,000).

(C) Method of Application. Applications in cases of emergencies shall be made to the Director or his/her designee by letter if time allows, and by telephone or in person if time does not allow.

(D) Necessary Information. The information to be reported during the emergency, if it is possible to do so, or to be reported fully in any case after the emergency, shall include the following:

(1) The nature of the emergency;

(2) The cause of the emergency, insofar as this can be established;

(3) The location of the emergency;

(4) The remedial protective, or preventive work required to deal with the emergency; and

(5) The circumstances during the emergency that appeared to justify the course(s) of action taken, including the probable consequences of failing to take action.

(E) Verification of Emergency. The Director shall verify the facts, including the existence and nature of the emergency, insofar as time allows.

(F) Criteria for Granting Permit. The Director shall provide public notice of the proposed emergency action with the extent and type of notice determined on the basis of the nature of the emergency itself. The Director may grant an emergency permit upon reasonable terms and conditions which shall include, at a minimum, an expiration date and the necessity for a regular permit application later, if the Director finds that:

(1) An emergency exists and requires action more quickly than permitted by the procedures for administrative permits or for ordinary permits, and the development can and will be completed within thirty (30) days unless otherwise specified by the terms of the permit;

(2) Public comment on the proposed emergency action has been reviewed if time allows; and

(3) The work proposed would be consistent with the requirements of the coastal program.

(G) Reporting.

(1) The Director shall report in writing to the Board of Supervisors at each meeting the emergency permits applied for or issued since the last report, with a description of the nature of the emergency and the work involved. Copies of this report shall be available at the meeting and shall have been mailed at the time that application summaries and staff recommendations are normally distributed to all persons who have requested such notification in writing.

(2) All emergency permits issued after the mailing for the meeting shall be briefly described by the Director at the meeting and the written report required by Subparagraph (1) shall be distributed prior to the next succeeding meeting.

(3) The report of the Director shall be informational only; the decision to issue an emergency permit is solely at the discretion of the Director.

(4) Notice of emergency permits shall be provided by phone or letter to the California Coastal Commission as soon as possible, but in any event within three (3) days, following issuance of the emergency permit.

(H) Compliance. An emergency permit shall be valid for not more than sixty (60) days from the date of issuance. Prior to expiration of the emergency permit, the permittee must submit a coastal development permit application for the development or else remove the development undertaken pursuant to the emergency permit in its entirety and the site restored to its previous condition. Failure to comply with the provisions of this section or failure to properly notice and report by the applicant any emergency actions may result in enforcement action pursuant to Chapter 20.552.
