10.24.020 - Permit—Required.¶
It is unlawful for any person to sponsor or conduct any special event or filming activity unless he or she first obtains a special event permit and the special event is conducted in compliance with all terms and conditions of that permit.
(Ord. No. 1411, § 1, 2-9-2016)
10.24.030 - Permit—Not required when.¶
A special event permit shall not be required for:
A. A regular and bona fide funeral procession;
B. Students going to and from school classes or participating in authorized educational activities, provided such conduct is under the immediate direction and supervision of appropriate school authorities;
C. Events which are expected to have fifty or fewer participants, do not require road closures or traffic control, and in which all participants are required to comply with the provisions of the California Vehicle Code.
(Ord. No. 1411, § 1, 2-9-2016)
10.24.040 - Permit—Application—Fee.¶
A. Any person desiring to conduct a special event shall file with the director a reservation request including the preferred date(s), a map depicting the course of the event, and the expected number of participants. Requests may first be filed during the first seven days of the calendar month being requested in the year preceding the preferred date (e.g. a request for a May 26 event can first be requested May 1 through May 7 of the preceding year). If at the end of this seven-day period, there are more requests than can be approved consistent with the provisions of this chapter for a given date or location, priority shall be given based on the number of years the event has been conducted on a similar date in the past (for example, the second Saturday in May). Following this initial seven-day period, dates shall be assigned consistent with the provisions of this chapter on a first-come, first-served basis.
B. Notwithstanding any other provision of the county code or policies, a waiver of the fee for special events shall not be approved by the director unless (1) the applicant is a local 501(c)(3) or 501(c)(4) organization or has designated a local 501(c)(3) or 501(c)(4) partner; and (2) a minimum of twenty-five percent of net revenues are designated for said local organization or local partner. The deposit required in subsection (F) below shall not be waived.
C. A complete application for a special event permit, including full payment of the base fee or approval of any request for waiver of the fee, shall be submitted to the director no later than ninety calendar days before the event, nor earlier than the first day that a request for a reservation can be filed pursuant to subdivision A of this section. Upon a showing of good cause, late applications may be accepted if filed sufficiently in advance of the date of the proposed special event to enable the director to thoroughly consider and investigate the application and the local commander of the California Highway Patrol informs the director there is sufficient time to enter into all traffic control contracts deemed necessary by that agency.
D. Applications for permits pursuant to this chapter shall also be accompanied by a deposit established by resolution of the board, to ensure cleanup of the event course of litter, debris or damage associated with the conduct of the event. Said deposit shall be used to perform cleanup or repair if the course is not left in satisfactory condition, as determined by the director. Balance of said deposit shall be refunded to applicant within thirty days of the completion of the event.
(Ord. No. 1411, § 1, 2-9-2016; Ord. No. 1419, § 2, 3-21-2017)
10.24.050 - Permit—Insurance requirements.¶
Before issuing a special event permit, the director shall require the applicant to file with the director a certificate of insurance showing that the applicant has obtained insurance in the amount of one million dollars to cover the liability of the applicant for property damage and/or injuries, including death, to any persons in connection with the activities conducted in accordance with the permit. The county and its respective officers, employees, and agents shall be named as additional insured on said certificate which shall further provide that it shall not be cancelled without thirty days prior written notice to county. It is a specific condition of each special event permit that the applicant shall maintain at least this level of coverage in full force and effect during the life of the license and thereafter as to activities which occurred during the life of the license.

(Ord. No. 1411, § 1, 2-9-2016)
10.24.070 - Permit—Application—Review by director.¶
Before issuing a special event permit, the director shall confer with the California Highway Patrol and such other governmental agencies or county departments as the director deems appropriate to fully review the application. The director shall issue a written permit as provided for in this chapter when, from a consideration of the application and from such other information as may otherwise be obtained, the director finds that:
A. The special event will not substantially interrupt the safe movement of other traffic or agricultural equipment and/or products, and is not reasonably likely to cause injury to persons or property on or adjacent to the route of the special event; and
B. The concentration of persons, animals and vehicles will not unduly interfere with proper fire and police protection of, or ambulance service to, areas where the special event will take place, or contiguous thereto, or the movement of any emergency equipment en route to an emergency; and
C. No other special event has been previously approved for the same time and place, or so close in time and place as to cause undue traffic congestion, or cause safety personnel to be unable to meet the safety and security needs of both special events; and
D. The special event is not to be held solely to advertise the goods or services of a particular business establishment or vendor; and
E. The special event has met all medical equipment, standby, and transportation requirements, and has paid all fees as established by guidelines and policies of the Napa County Emergency Medical Services Agency. The requirements may include first-aid stations, physician support, ambulance transportation, and access to emergency medical supplies and equipment. Emergency medical requirements will be based on the size, location, and duration of the event. Medical response plans must be approved by the Emergency Medical Services Agency prior to issuance of a special event permit; and
F. There will be a maximum of two events per month at any location on an arterial roadway; and
G. There will be a maximum of one event per weekend at any location on an arterial roadway.
H. Notwithstanding the provisions of subsections (F) and (G) above, one additional event may be permitted on a given date if the combined maximum participant load of all special events occurring on that date at any location does not exceed three thousand.
I. Relay events are not permitted on State Route 29 or on Silverado Trail north of Trancas Street.
J. The special event or applicant for said special event was not, during the prior calendar year, found to been in violation of a particular requirement of a permit for a third special event in a row. This finding shall not prohibit the director from denying a permit as a result of any singular violation of a permit if the director, based on that violation, is unable to make any other finding required by this section.

10.24.110 - Permit—Revocation conditions.¶
The director may revoke a special event permit at any time if, in the opinion of the director, conditions exist which may significantly affect the safety of event participants and/or traffic, or if the applicant violates any condition of the permit. The director shall immediately notify the applicant of such revocation and the reasons therefor. For purposes of the appeal procedure set forth in Section 10.24.120, such revocation shall constitute a denial of the permit.
