Lyme — Residents in ballot voting on Tuesday rejected a zoning amendment that would allow clustered housing, or a so-called “pocket neighborhood,” near the center of town.

The measure, long-sought by proponents of the Pinnacle Project, a proposed co-housing development near Post Pond, was defeated 300-226.

Voters approved by wide margins three other zoning amendments, including content-neutral sign regulations and a measure regarding accessory dwelling units.

But a petitioned warrant article to adopt a three person board of assessors failed 336-145.

Lyme currently hires a professional assessor for such duties.

Also by ballot, Bradford “Rusty” Keith was elected to an open Selectboard seat, and Carole Ann Tullar, with 284 votes, and Hayes Greenway, 228, won two open seats on the School Board, outpacing Jonathan Voegele, 208, and Jennifer Boylston, 141.

On Wednesday, two leaders of the Pinnacle Project thanked residents for their support of the pocket neighborhood amendment via the Lyme listserve.

“Although the measure didn’t pass, we received lots of good thoughts about ways that Lyme can evolve,” wrote Rich Brown and Liz Ryan Cole.

“We will continue to work actively with the Selectboard, the Planning Board and our friends and neighbors to think broadly about options for property tax sensitive housing and business development in Lyme.”
