Board discusses irrigation‑code changes and wetlands permitting for turf irrigation

As part of a wetlands‑code rewrite the board reviewed how turf irrigation systems should be treated when work occurs inside the proposed 100‑foot regulated wetlands buffer. Staff recommended that conversion, replacement, or new turf irrigation that intrudes on the wetlands buffer require an administrative wetlands permit (a short process without a public hearing that can be escalated when significant impacts are suspected).

Board members and staff agreed that drip (non‑turf) irrigation is functionally different and generally does not require the same permitting because it does not require trenching. One board member proposed carving out an explicit exemption for seasonal flower and vegetable gardens under 400 square feet to avoid requiring permits for small household gardens. "Drip irrigation system requirements will exclude seasonal flower and vegetable gardens no greater than 400 square feet," the member suggested as draft language to carry into the code.

Staff said the wetlands subcommittee will insert consistent language in both the grandfathered‑system section and the new turf‑system sections so applicants will be alerted early in the application process that work inside the wetlands buffer triggers a short administrative review; significant changes can still be routed to a full wetlands process. The board asked staff to include the language in the package set for the public hearing later in August.
