The Planning and Zoning Board (P&Z) approved construction of two beach houses at its June 20 meeting.

The board unanimously approved an application for a special permit and coastal area management site plan to allow construction of one single-family residence each on two different waterfront parcels.

In presenting the application for the property at 104 Beach Ave., Architect John Ruffalo III said the 3,400 to 3,500-square-foot new house would be three stories with a detached garage on a legal non-conforming lot.

Mario and Grace Perone are the owners of the 0.15-acre property. The parcel formerly had a three-story house on it, but is currently vacant land.

Board member John Grant, who occasionally challenges architects on building heights listed in site plans, complemented Ruffalo.

“You are the first person who actually read our regulations to figure out the average grade,” said Grant, commenting on the calculation needed to determine the average grade of the property.

Leigh Dwyer received approval to construct a house at 20 Bridgewater Ave., on property owned by Reza Manzouri. Manzouri purchased the 0.1-acre property in the R-5 zone on Nov. 17, 2015 for $242,000. The lot currently has a foundation for the former house that has been razed.

This was a reapproval of an application the board approved in August 2015. The reapproval was necessary because the applicant did not start construction within 12 months of the permit being issued.
