City updates street-tree programs; hazard removals cost-share and winter clearance pruning remain in high demand

Lexington’s urban forestry staff on June 10 briefed the Environmental Quality and Public Works Committee on street-tree programs, saying demand for hazardous-tree removal and replacement assistance remains high and that the city is working to expand proactive maintenance and inventory tools.

The update came from Heather Wilson, urban and community forestry section manager, who described two core programs: a Hazard Street Tree Cost Share that reimburses homeowners for hazardous street‑tree removal and replacement (typically a 50% reimbursement; 100% grants available to households under an income threshold) and a Courtesy Street Tree Clearance Pruning program that prunes limbs over sidewalks and roadways.

Why it matters: Street trees provide environmental and social benefits such as shade, stormwater mitigation and improved walkability. Wilson said it is less expensive to maintain a healthy urban canopy than to do deferred repairs and repeated emergency removals.

Program details and demand: Wilson told the committee that roughly 90% of street trees are on private property and are the adjacent property owner’s responsibility; “about 10% of those street trees … are actually owned by the LFUCG, and we manage directly,” she said. The cost-share program historically ranged near $150,000 annually; a pandemic-year reduction briefly lowered that budget, but demand and per-tree costs later returned. City allocations were bolstered in one year by a $1.5 million infusion to clear backlog and support 100% grant recipients.

For the current fiscal year the program received roughly 72 participants (Wilson later corrected to 96 total participants across the fiscal year with 11 receiving full grants). Wilson said program funds typically exhaust by September each year and that the per‑tree removal and replacement cost has increased over the past decade.

Clearance pruning and inventory: The clearance pruning program expanded beyond routes tied to waste‑collection truck paths to citywide coverage; staff estimate it has pruned roughly 38,000 trees through that program. Wilson said trees generally need pruning on a 3-to-5-year cycle and that the department aims to move from clearance-only pruning to broader crown cleaning for long-term canopy health.

Equity, species diversity and future needs: Wilson said the department is working with vendors to expand replacement species diversity to avoid dependence on a single species. She also urged more complete mapping and a comprehensive tree inventory; the department purchased inventory software and staff are beginning data entry but said the work is time-consuming. Wilson described a longer‑term goal of city management of easement trees to ensure consistent care, but she noted that would require additional staff and funding.

Requests and next steps: Council members asked about enforcement of developer planting plans, timing of plantings, and whether the city could fund replanting-only programs. Wilson said enforcement involves planning review, the urban forester and natural resources protection staff, and that inspection/timing issues (for example fall planting season) explain some observed gaps. She said a separate planting fund would be a desirable future budget item.

Context: Wilson framed the program as part of broader resilience and quality-of-life efforts that intersect with the city’s climate work and changing weather patterns. She asked the committee to support continued investment in inventory, pruning and planting programs.

Closing: The committee did not take formal policy action during the briefing; staff said program details and maps could be shared publicly and with council members for follow-up.
