Recreation and Park Commission Reviews Shadow Impact on Four San Francisco Parks

San Francisco's Planning and Recreation and Park Commissions convened on July 17, 2025, to discuss the proposed Sansom mixed-use tower and Fire Station 13 project, which is set to rise 545 feet and cast new shadows over four local parks. The meeting focused on the implications of these shadows, particularly in relation to the city's established shadow policies aimed at protecting park properties.

The key decision at hand involves whether to raise the absolute cumulative shadow limits for Washington Square, Willy Woo Woo Wooang Playground, Maritime Plaza, and Sue Bierman Park. These parks are protected under the 1989 Planning Code Section 295, which prohibits new developments from casting significant shadows unless deemed acceptable by the commissions. The staff recommended approval of the project, asserting that the new shadows would not have a significant adverse impact on park usage.

During the presentation, staff outlined the current shadow loads on each park and the minimal increases expected from the new development. For instance, Washington Square currently experiences a 7.47% shadow load, which would increase to 7.48%. Maritime Plaza, already under 67.84% shadow, would see an increase to 69.92%. The analysis indicated that the new shadows would primarily occur during specific times of the year, with minimal overall impact on park activities.

The meeting also highlighted community feedback, with one letter of opposition from a nearby resident and three letters of support from local organizations, including the San Francisco Chamber of Commerce. The staff emphasized that the project aligns with the city’s general plan and downtown area objectives, framing it as both necessary and desirable for the community.

As the commissions prepare to vote on the proposed changes, the outcome will determine the future of the project and its impact on San Francisco's cherished public spaces. The decision underscores the ongoing balance between urban development and the preservation of the city's parks, a critical issue for residents and stakeholders alike.
