San Francisco advances Treasure Island sustainable neighborhood development plan

The San Francisco County government meeting held on July 4, 2025, focused on the ongoing development of Treasure Island, highlighting significant advancements in infrastructure and housing. The meeting began with a presentation on a development agreement aimed at creating a sustainable neighborhood, which has received recognition from LEED as a platinum-level design, marking it as the largest project to achieve this status.

The proposal discussed was twofold: first, to endorse a shared vision emphasizing inclusion, equity, sustainability, opportunity, and connection in the development process. If adopted, this endorsement would become city policy. Secondly, the development agreement included changes intended to sustain momentum on the island, ensuring continued tax revenue and the creation of affordable housing, with 27.2% of new units designated as affordable.

The meeting detailed the current state of development on Treasure Island, noting that nearly 1,000 homes are either completed or nearing occupancy. Infrastructure improvements, including parks, utilities, and public art, have been accepted by the city and are now in use. The construction of 991 housing units is underway, demonstrating San Francisco's capacity to build housing despite global uncertainties.

Key infrastructure upgrades include seismic safety enhancements and adaptations for anticipated sea level rise. New utilities and street improvements are being implemented, with a new water treatment facility under construction. The meeting also highlighted the opening of a new ferry landing, which will significantly reduce travel time for residents.

As the meeting progressed, it was noted that the existing wastewater treatment plant is set to close in 2026, allowing for further development of vertical buildings. Currently, 229 units are complete, 745 are under construction, and 360 are in the planning stages, with the next building, Starview Court, designated as 100% affordable housing.

The meeting concluded with a focus on maintaining the project's progress and ensuring that the next phase of infrastructure development remains on track. The overall sentiment was one of optimism regarding the future of Treasure Island as a vibrant and sustainable community.
