The commission reviewed multiple buffer‑zone topics including whether pervious surfaces that do not support vegetation should require mitigation, how to handle vistas (view corridors) that cross properties, and formalizing a 10‑foot no‑structure zone from the limit of work.

Staff said gravel, crushed stone and dry‑laid patios in the B‑zone have in practice escaped mitigation and recommended closing that gap because cumulative loss of vegetated buffer is occurring in the field. Commissioners supported revising buffer rules but asked staff to gather redlined language and examples before finalizing.

Separately, the commission agreed it would be helpful to explicitly note in the regulations a 10‑foot no‑structure band from the limit of work to aid enforceability around staging, ladders and foundation work — a practice that staff said evolved from construction experience. Commissioners also discussed whether to allow vistas that traverse multiple properties and flagged coordination and tax/assessor implications if multiple owners were involved.

Next steps: staff will prepare talking points and a consolidated package of buffer‑zone revisions (pervious surfaces, no‑structure band, vista policy) for the commission to review at future meetings.
