Subject: Clipper Cove Marina Development - Compromise Reached

TISC and Treasure Island Enterprises (TIE) have settled on a compromise for the footprint and location of the marina proposed for Clipper Cove.

The November 2, 2016 TIE plan, which addresses the minimum space needs of TISC programs, includes two critical dimensions:

  • The eastern edge of the transient dock will be located no more than 1,144’ from the west end of the cove. This placement provides adequate space - protected from waves, current and commercial traffic - for beginner sailors to practice sailing upwind in Clipper Cove.
  • The southern-most point of the 789’ transient dock and its 236’ extension will be limited to a 1,014’ protrusion into Clipper Cove. That length, about 2/3’s the distance from Treasure Island south to Yerba Buena Island, opens a passage to the beach that is sailable by many beginning sailors.

While this footprint will reduce the range and depth of some TISC programs, it does provide the minimum space needed to access the beach and continue all our current programs in the cove. TISC acknowledges the meaningful changes TIE made that will allow our programs to continue and we want to thank our community for their support during this challenging negotiation.

The TIE plan, including key dimensions for the eastern position and southern tip of the transient dock with its extensions, is located here: ("OVERALL SITE PLAN - MARINA - Adjusted Slip Configuration dated 11-2-16").

Subject: Clipper Cove Marina Development – October 2016 Update

Below are two documents that summarize meetings and discussions held, and analyses completed during September and October, 2016 regarding our progress on keeping Clipper Cove open for Treasure Island Sailing Center programs as well as for access by the general public.

The first document – Shared Approach Overview – contains the TISC position, program needs and rationale for our proposed shared approach solution for the use of Clipper Cove, including two compromise options and supporting analysis.

A second document – Clipper Cove Marina Expansion Economic Feasibility Study– provides a cash flow snapshot of three marina configurations, including development costs, dredging costs, and operating costs and revenues. Our analysis found that a range of marina configurations is economically feasible, including a 306-slip shared-use marina layout.

Thanks to the support of so many of our participants, parents, friends and partners, we feel a resolution for shared space in Clipper Cove is now on the horizon.

Subject:  Cliper Cove Marina Development - Overview of Current Marina Development plans


As many of you know, the development of Treasure Island is moving forward.  This project has been in the planning process for some time and we are looking forward to a day when the island is a vibrant new neighborhood of San Francisco. Thankfully, the Treasure island Sailing Center is a part of the future development plans and will have a home adjacent to our current location. 

The shoreside space and facilities outlined in the development plan is perfect.  It will allow us to teach thousands more kids each year and will allow us to expand public access to the cove in sailboats, kayaks and stand up paddle boards, if we have enough safe, protected water to do so.  Unfortunately, we (the TISC Board of Directors) cannot support the scope and location of the marina planned for Clipper Cove.  We are extremely concerned that the scale of the Marina, as most recently proposed (Overview of Current Marina Development plans).  The elongated wave attenuator and its footprint extended to the East of the Cove, will significantly reduce and negatively impact youth sailing and community recreation in the Cove. The proposed footprint places the recreational area so far to the east of the Cove that a third of it is in strong current presenting challenges that will limit the scope of our educational and recreational programs and require us to re-structure our programs in a way that will limit service offerings to our youth sailors, adaptive sailors (sailors with special needs) and the public at large. 

Currently, we teach over 1800 kids per year, 89% who qualify for a partial or full scholarship.  We also have public events that attract between 550 to 700 people in a day who want to recreate on the Cove. And, we expect the demand for public sailing and other water recreational opportunities (Kayaks, SUPs) on the Cove to rise dramatically over the next 10 years as Island development proceeds.  After much research and consideration, we have identified that a 1600 foot diameter sailing circle out of the current is essential for safe and accessible recreation in Clipper Cove (TISC Proposal).  

Therefore, we are asking public officials and other constituents to immediately and comprehensively review the scale of the marina project to ensure that Clipper Cove remains accessible to all San Franciscans.  There is only one Sailing Center in San Francisco and it ensures that any San Franciscan has the opportunity to enjoy and connect with the Cove. 

Let’s work together to ensure that Clipper Cove remains open and accessible to all. Please take the time to read some of the information on this topic and voice your opinion using the suggestions below.
