I contacted the Treasure Island Development Authority as requested and got an email reply from them. As of now, Treasure Island, San Francisco, CA drone flying is considered a special event that requires permission after submitting an application for a use permit with a proof of specific insurance requirements. This is what I received:
Special Event Insurance Requirements:
In addition to issuance of a Use Permit, Event Producers are required to carry
adequate liability insurance coverage for all Special Events held on Treasure Island.
Minimum insurance requirements are listed below, but these requirements may be
modified or increased depending on the nature of the event:
Workers Compensation insurance with limits not less than $1 million;
Employers’ Liability Coverage with limits of not less than $1,000,000 for each
accident or occurrence, Comprehensive or Commercial General Liability
Insurance with limits not less than $1,000,000 each occurrence, $2,000,000
aggregate for bodily injury, property damage, contractual liability, personal
injury, products and completed operations.
Automobile Liability insurance with limits not less than $1 million.
A Certificate of Insurance confirming coverage and an Endorsement for Additional
Insureds form (known as a “Form CG 20” or equivalent) are both required. The
following entities must be endorsed as Additional Insureds on all policies required of
the Event Producer: “Treasure Island Development Authority, City and County of
San Francisco, United States of America, acting by and through the Department of
the Navy, and their officers, directors, employees and agents”.
One-Day Special Event General Liability Insurance coverage is available for
purchase through TIDA on a sliding fee scale based on the nature of the Special
Event and the number of participants. Event Promoters may request more
information from the Authority regarding the availability of this coverage if they do
not carry Liability Insurance themselves.
