Albany consultants recommend proactive street‑tree program, 150 trees/year planting target

Consultants for the City of Albany presented a draft Street Tree Management Plan to the Park, Recreation & Open Space Commission, recommending the city move from a primarily reactive maintenance model to a proactive, programmatic approach that would aim to increase street‑tree canopy and formalize responsibilities for planting and removals.

Jeff Bond, Community Development Director, opened the presentation and turned the discussion over to consultants from HortScience/Bartlett Consulting: Daria Berar, managing consulting urban forester, and Ryan Settle, consulting arborist. The consultants reviewed the plan’s structure (Chapters 1–6), analysis of the current street‑tree inventory, benchmarking with peer Bay Area cities and, most substantively, the plan’s goals and recommended actions in Chapter 6.

The draft sets a near‑term canopy objective for street trees and recommends a citywide planting strategy focused on species and age diversity, climate‑adapted selections and planting the “right tree in the right place.” Consultants said street trees now account for roughly 4% of Albany’s overall canopy; the plan recommends raising that street‑tree share to 5% canopy cover and tracking progress via periodic remeasurement (the presentation recommended remeasuring canopy about every 10 years using tools such as i‑Tree Canopy). To meet the goal, the consultants recommended planting roughly 150 street trees a year, subject to available planting space, budget and staffing.

The plan urges the city to codify responsibility and standards for proactive public tree maintenance, shifting from the current shared maintenance agreement toward clearer city authority. Key management recommendations include adopting a multi‑year inspection and pruning cadence (for example, inspection cycles every 5–7 years), defining the city arborist (city manager designee) as the decision‑maker on public tree removals for safety reasons, and revising street‑tree removal criteria to reference accepted arboricultural risk‑assessment standards and plant appraisal guidance.

Consultants discussed species selection principles: prioritize climate‑adapted trees that are likely to thrive now and under future projected conditions, preserve existing species and age diversity, and match tree geometry and water needs to site conditions. They cited examples such as silver leaf oak and Nyssa sylvatica (black tupelo) as species that can provide desired canopy and aesthetic outcomes in some Albany sites, and suggested using climate analogs (the University of Maryland Center for Environmental Science climate‑analogy approach was mentioned) to test species suited for future conditions.

Commissioners raised questions about implementation details and tradeoffs. Commissioners and staff discussed the limited planting space in parts of the city—particularly on the west side of Albany Hill and pockets south of the hill—where narrow sidewalks, parking and utility constraints limit tree wells. Consultants and staff said some equity‑focused canopy gains would require more costly infrastructure changes such as concrete removal or sidewalk widening and that those projects would likely need separate capital funding decisions. Staff noted the city has performed sidewalk modifications in previous repairs to expose and expand planting space when feasible.

Commissioners and consultants also discussed lifespan and turnover assumptions. Commissioners observed that average street‑tree lifespans used in some benchmarking can vary; staff said Albany’s tree removal data show fewer than 20 public street trees removed per year in recent years, and consultants said local removal rates and inventory data were incorporated in planning projections. The consultants acknowledged lifespan estimates vary by species and climate and said their 150‑tree target was shaped by Albany’s local inventory and capacity assumptions.

Sidewalk damage and root conflicts featured throughout the discussion. Commissioners requested the plan explicitly address sidewalk impact potential for recommended species. Consultants said they would incorporate sidewalk‑damage ratings (Cal Poly ratings were cited) and make species recommendations that account for root damage risk, available parkway width and appropriate mature size for each location.

The draft also recommends stronger outreach and community engagement steps: create an inclusive outreach program, expand volunteer planting and stewardship events, add clear web guidance about tree protections and maintenance responsibilities, and apply for Tree City USA status (the plan says Albany already meets many of the program’s criteria). Consultants recommended the city monitor canopy and program performance periodically and treat the plan as a living document to be revisited as data and community priorities evolve.

Commissioners suggested the plan include: (1) clearer descriptions of the commission’s role in reviewing non‑safety removals and removals that affect neighborhood character; (2) a mechanism for routing non‑emergency removal requests and exceptions to the commission when appropriate; (3) a clearer list of benchmarking cities, including cost examples for proactive maintenance; and (4) explicit references to sidewalk and root conflict mitigation in the species‑selection guidance. Consultants and staff said they will revise the draft to incorporate that feedback and to prepare a community engagement event to solicit additional public comment before issuing the plan for public review.

The commission discussion yielded no formal action or vote on the plan. Staff said the consultants will return with a revised draft and with budget projections and a public‑engagement schedule in the next month or two.

Ending: The commission asked staff and consultants to (1) add sidewalk‑damage ratings to species recommendations, (2) clarify what decisions would remain with the city arborist for safety, (3) outline how the commission would be engaged on removals not deemed emergencies, and (4) include benchmarking cost examples. Consultants said they will incorporate the requested clarifications and return with a public outreach plan and a revised draft for further review.
