Mountain View board denies heritage-tree removal at 2415 Benjamin Drive

Mountain View’s Parks and Recreation and Urban Forestry Board on Feb. 11 voted to deny an appeal seeking removal of a heritage tree at 2415 Benjamin Drive, upholding staff’s recommendation that the tree not be removed under current evidence.

Forestry Manager Russell Hanson told the board the subject is a Podocarpus gracilias about 22 inches in diameter that is in good health and fair structure, with only minor canopy imbalance. Hanson said staff found no evidence the tree’s condition met the city's removal criteria and that issues alleged by the applicant could likely be addressed through corrective pruning or targeted root work rather than removal. "We did not find that the condition of the tree required its removal," Hanson said during his presentation.

Why it matters: the tree is designated as a heritage specimen under city code and removal requires specific findings. The property owner or an authorized applicant may seek removal, but the board must weigh preservation against claims of damage. The appellant’s representative said the tree has caused foundation and driveway damage, described a driveway he said was lifted about 1.5 inches, and said prior sewer repairs cost roughly $59,000. "We believe the tree should be removed because there's damage to the foundation," the appellant’s representative said.

What staff found and why they recommended denial: Hanson and staff reported the tree sits close to a marked gas line and between two homes (staff estimated distances of about 43 inches to one house and 50 inches to the other). Staff said gas service lines on the site are likely flexible polyethylene and operate at very low pressures, and that PG&E markings were used to estimate the line location. Staff also said a 2024 trenchless pipe-lining job carried a roughly 20-year warranty that covers the liner but does not cover future root intrusion. Hanson told commissioners that targeted excavation (including hydro-excavation) and root pruning could identify problematic roots and, if limited to smaller roots outside a roughly 3-foot radius from the trunk, could mitigate many hardscape issues while preserving the tree.

Questions and evidence: commissioners pressed the appellant and staff for floor plans and documentation showing the radiant-slab heating and the exact relationship of heating lines to the tree. The applicant said the house has radiant heating embedded in the foundation slab and warned that cracking the slab would damage the heating system. Staff and multiple commissioners said that information was new to them and that it would have been helpful if included in the original application packet.

Board decision and next steps: after deliberation a motion to adopt a resolution denying the appeal and denying removal of the heritage tree passed by the board. Commissioners said the tree appears healthy and is an asset to the neighborhood and that mitigation and more precise documentation (floor plans, root-exploration results) should be pursued before removal is considered. Several commissioners noted reapplication is possible if new evidence shows intrusive roots into the living structure.

Context and process notes: Hanson acknowledged some communication issues around submitted materials and said staff will reinforce guidance to applicants about what must be in the initial packet when seeking removal or appeal. The appellant said they had filed the appeal in August and that earlier notification or clearer guidance would have allowed them to submit supporting evidence sooner.

The board’s ruling preserves the heritage tree for now; staff said property owners may return with new, substantiating evidence and that mitigations such as targeted excavation or pruning could be explored before any new removal request is accepted.
