Olivette planners debate tree‑canopy rules and options for replacement after redevelopment

During other business the commission devoted substantial time to tree‑canopy policy as part of the comprehensive plan update. Staff presented comparative approaches used in nearby municipalities and recommended the commission decide whether the city should require replacement based on canopy area (coverage) or tree caliper (one‑for‑one), and whether higher‑quality species should offset removals.

Commissioners voiced frustration that redevelopment often removes mature canopy and proposed several possible tools: adopting canopy‑equivalency metrics, requiring on‑ or offsite plantings tied to demolition, hiring an arborist or consultant to vet species and planting lists, and creating clearer enforcement for tree‑protection fencing during construction. Commissioner comments captured a range of approaches: "If you're gonna be knocking down 10 trees and you're not gonna be able to put 10 trees up, let's put 10 trees elsewhere," one commissioner said, urging explicit mitigation requirements.

Staff offered to distribute a table comparing tree‑replacement rules and canopy standards from Clayton, Webster and other municipalities and suggested compiling guidance so the commission can provide clearer direction to developers. The commission asked staff to return with options, including costs and practical implications for enforcement and stormwater conflicts (noting the difficulty of planting canopy trees where flow wells or utilities are placed).

The discussion did not produce a binding policy change; commissioners requested additional information and dedicated time in future meetings to work through tradeoffs between canopy preservation, site constraints, and stormwater infrastructure.
