Norwalk council adopts 30-year tree master plan, sets 10% canopy-growth goal

The Norwalk Common Council voted unanimously April 22 to adopt the city's Tree Master Plan, a 30-year strategy that sets a target to increase tree canopy by 10 percent by 2053.

The plan, presented to the council on Earth Day by Sarah Cruz, the city's arborist and horticulturist, and Chris Piper of consultant Planet Geo, lays out planting priorities, a public-tree inventory, maintenance strategies and neighborhood-level targets to address canopy deficits in urban neighborhoods such as South Norwalk.

"Trees are essential public infrastructure," Sarah Cruz told the council. "They filter our air and water, cool neighborhoods, support wildlife, and manage stormwater." Cruz said the plan centers on three goals: growing canopy, improving maintenance to reduce risk and strengthening community engagement and stewardship.

Planet Geo's director of urban forestry strategy, Chris Piper, said the plan is based on a top-down canopy assessment and a bottom-up inventory of public trees. The consultants estimated Norwalk's canopy at 43 percent of the city's land area (about 6,200 acres), down from 49 percent in 2012, a loss of roughly 790 acres. The plan identifies priority neighborhoods and sets phased actions: immediate inventory and planting steps, short- and midterm program expansion and longer-term funding and policy work.

Council members emphasized equity and financial questions during debate. Council Member Burnett said he did not see detailed financial backup in the packet and asked what approval would commit the city to financially. City staff said the implementation strategy will rely on a combination of capital funding, grants, private partners and volunteers. Cruz and other speakers said the consultant modeled a mix of funding and delivery: the city assuming roughly 70 percent of planting responsibility with the remaining 30 percent expected from private development, homeowners and community organizations. Staff estimated a notional cost of about $900,000 per year if all city-led plantings were contracted, and said volunteer and partner planting would reduce that burden.

Speakers representing community partners said Norwalk already has active volunteer groups. A council member representing the Norwalk Land Trust noted recent volunteer plantings and grant fundraising that have supported hundreds of trees. Several council members said the plan will help the city compete for grants by providing a data-driven roadmap.

The council adopted the plan without recorded opposition. The motion to adopt was introduced by Council Member Shanahan and carried unanimously when the mayor called the vote.

The plan calls for an immediate public-tree inventory, a prioritized planting schedule for neighborhoods with the greatest deficits, proactive maintenance and pest and risk management, and a coordinated education and volunteer program. Implementation steps are organized into immediate, short-, mid- and long-term timeframes in the draft presented to the council.

Supporters said expanded canopy could also reduce stormwater impacts and public-health costs in neighborhoods with higher heat and flooding vulnerability. The council and staff said next steps include outreach to volunteers, grant-seeking and incorporating the plan into capital and operating budgeting processes.

The council's unanimous vote makes the Tree Master Plan an official city guidance document and positions Norwalk to seek outside funding and to begin phased implementation with partners and volunteers.
