Board of Appeals conditions removal of two ficus on Sixteenth Street on 36‑inch magnolia replacements within three months

The San Francisco Board of Appeals on June 26 voted 4‑0 to grant an appeal concerning a Public Works order to remove two large ficus trees in front of 3030 Sixteenth Street, and to impose conditions on any removal. The board’s action requires Public Works to replace the trees with two Magnolia grandiflora, each in a minimum 36‑inch box, within three months of removal.

Appellants urged the board to preserve the trees, listing public‑safety and neighborhood benefits including pedestrian shade, cooling in the Mission’s hot summers, stormwater absorption, air‑quality value, wildlife habitat and the trees’ aesthetic and emotional value. A speaker representing neighbors pointed to arborists’ guidance that pruning and maintenance often can preserve mature trees.

Chris Buck, Urban Forester for San Francisco Public Works, told commissioners that the two subject trees are mature ficus with codominant stems, narrow angles of attachment and multiple competing trunks — structural conditions that have led to increased failures of ficus citywide. Buck said Public Works has lowered its threshold for approving ficus removals under public‑works order 183151 (the agency’s ficus removal criteria) after observing repeated stem and branch failures in several neighborhoods.

In response to commissioner questions, Public Works committed to a 3‑month target for replanting following removal (shortening the department’s typical six‑month window), said it would fund planting and watering for the replacements, and described plans for robust staking and protection of young trees. Buck also said the agency prefers pruning and mitigation where practicable but judged these two trees structurally unsafe. He estimated replacement trees will show noticeable canopy in roughly 10 years and will take decades to reach the size of the existing trees.

Commissioners repeatedly pressed Public Works on ensuring replacements are actually planted and maintained, citing past delays in other neighborhoods; Buck described recent district infill plantings, community meetings, and steps to secure funding for watering and maintenance. The board’s motion, made by Commissioner Darryl Honda and approved unanimously, conditions any removal on the required replacements and a three‑month replacement timeline.

The decision leaves in place Public Works’ finding that the existing trees pose a hazard while adding an explicit, time‑bound replacement requirement intended to limit canopy loss in the short term and ensure replacement plantings are installed and maintained.

Next steps: Public Works will be responsible for implementing the conditioned removal order, planting the two replacement Magnolia grandiflora (minimum 36‑inch box), and complying with the three‑month timeline; the board did not set separate enforcement language beyond the conditioned requirement, but commissioners indicated they expect follow‑up documentation and reliable watering commitments from the department.
