After months of public hearings, frequent delays and long deliberation, the Inland Wetlands Commission on July 13 approved some development on a subdivision proposal from the estate of the late jazz pianist Dave Brubeck, but denied others.

Up for consideration was a six-lot reconfiguration of property owned by the Brubeck Trust. The addresses are 221 Millstone Road and 67, 69, 73, 85, and 87 Hickory Hill Road.

The board approved significant regulated activities on lot 5, lot 6 and lot 7 with conditions, but denied without prejudice the proposed activities on lot 1B, lot 8, lot 9 and lot 10.

“It’s a very complicated project,” board member Tom Burgess said in June. “We have to give it our time.”

Attorney Casey Healy, who is representing the Brubeck trust, could not immediately be reached to comment on his client’s reaction to the decision. He had said before that more information was provided for this case than is typical for a commercial development, and the Brubeck family has tried very hard to answer all questions and concerns in a spirit of goodwill with the community.

The Brubecks moved to Wilton in 1962. A subdivision was approved there in 1954 and again in 1968.

Part of what complicated the proposal is that the land is the equivalent of two football fields and is full of wetlands, including the Comstock Brook, members said.
