Essex planners debate tougher RPDI buffer rules and separate 50/100/200-foot standards

The Essex Planning Commission spent the bulk of its July 9 meeting debating proposed revisions to RPDI buffer rules, focusing on whether the zoning should treat 50-, 100- and 200-foot buffers as distinct elements with separate purposes and criteria.

Staff presented draft language that would make clear buffers should be dense and natural-looking and suggested limiting waivers in certain buffer zones. Commissioners repeatedly urged separating the three buffer widths into individual sections, arguing each serves a different purpose—separation from residences (200 feet), separation between businesses (100 feet) and separation between business and road (50 feet).

Commissioners also discussed technical details: what planting mixes achieve visual screening and noise mitigation, minimum planting sizes and timelines to achieve screening, line-of-sight and safety exemptions where tall plantings could obstruct views, and whether the regulations should reference an annually updated planting guideline rather than listing species in the zoning text. One commissioner read a draft sentence the panel liked: "Each location will have unique circumstances and will thus result in unique designs, but all designs shall include taller canopy trees, red oak, white pine, etcetera, understory, and low level shrubs," then debated whether the word 'shall' boxed the town into prescriptive requirements.

The commission repeatedly flagged practical issues: existing mature trees may not provide the desired understory, utility intrusions and sidewalks sometimes cross buffer areas, and some buffer locations include wetlands subject to state rules. Several members proposed that a town arborist or tree warden review planting plans and that the commission adopt an external landscape guideline document as a reference that can be updated periodically.

Public commenters reiterated the resource-preservation goals of the RPDI district. Anne Miller, speaking as an Essex resident, urged the commission not to lose sight of the district's preservation purpose when dividing buffer rules into separate categories.

Next steps: Commissioners directed staff to prepare a revised draft that delineates the 200-, 100- and 50-foot buffers, states the purpose for each, and includes requirements for a landscape plan and maintenance schedule. The commission emphasized immediate attention on the 50-foot buffer while reserving broader refinements for future drafts.
