Theater and office uses for two of the three remaining buildings on the town\u2019s former Schlumberger property won the Planning and Zoning Commission\u2019s unanimous approval Tuesday, July 18, after a public hearing that discussed a traffic consultant\u2019s report recommending study of the eventual need for a traffic light at Grove Street and Old Quarry Road. The town\u2019s plans would prepare the 30-acre site for leases to two tenants, and include a loop road using the two existing driveway locations off Old Quarry Road and a total of 142 parking spaces, said Steven Sullivan of the engineering firm CCA. The town\u2019s intended tenants are New Canaan-based design firm BassamFellows, which will have offices in the Philip Johnson Building \u2014 known by the name of the architect who designed it \u2014 and the nearby auditorium will be leased to ACT, A Contemporary Theater, which plans to put on musicals and plays. Over the winter, town meeting voters approved leases that require the two tenants to bear the cost of renovating the buildings, which have fallen into disrepair since the town\u2019s purchase in 2011. The 142 parking spaces in the plans \u2014 some in parking lots, others along the loop road \u2014 are envisioned as also eventually also serving public uses that have been envisioned on the site, such as hiking trails or a cultural center with an outdoor stage. A bluestone patio would be added near the entrance to the theater, street trees would be planted along the loop road. An \u201cevergreen buffer\u201d would separate the proposed parking from the 54-unit development of coach homes and condominiums off Sunset Lane on 10 acres of former Schlumberger land sold by the town to the developer Charter Group Partners. Joanne Motta, a property owner on Sunset Lane, was the one member of the public to speak at the hearing. She was troubled by already heavy use of roads in the vicinity \u2014 Grove Street, Old Quarry Road, and Sunset Lane. \u201cI\u2019m just concerned because of the traffic \u2014 people have been using that as a thoroughfare,\u201d she said. \u201cNo speed limits.\u201d Commission member Stephen Cole said the town\u2019s addition of theater and office uses south of Old Quarry Road should be considered in the context of a recent approval for five acres on the north side of Old Quarry Road for a long-term care facility and a mixed-use building with apartments over a storage facility. \u201cOld Quarry Road, today is a bypass road \u2014 nothing on the right side, nothing on the left side,\u201d Cole said. Soon, there\u2019ll be active uses on both sides of the street. First Selectman Rudy Marconi reminded the commission that, while the site might be mostly empty today, it had a history of more intense use. \u201cWhen Schlumberger was there, there were 150 to 200 employees at their peak,\u201d Marconi said. Town Engineer Charles Fisher, who headed up the town\u2019s presentation, said the traffic report by Frederick P. Clark Associates counted 240 vehicles going east and 180 going west at the site on peak commuter hour. The town\u2019s proposed lease of the 107-seat auditorium to the theater group is expected to add \u201c59 cars coming in\u201d when \u201cthe auditorium is active\u201d on a Friday or Saturday evenings \u201cWe\u2019re at most adding 20% more vehicles\u201d to traffic at the site when there are productions at the theater, said Fisher. The Frederick P. Clark Associates\u2019 traffic report predicted \u201cinsignificant impact, if any\u201d from the plans, Fisher said. \u201cI\u2019m confident you\u2019re not going to see a big change when auditorium is in operation, based on this report,\u201d Fisher said. There was less discussion about the Philip Johnson Building, which BassamFellows will use to show-off its contemporary furniture. Commissioner John Katz sought assurances that the tenant would not be using the site for retail sales \u2014 the area is governed by a B-2 business zone which allows only limited, incidental retail uses. \u201cIt was my recollection there was to be no retail,\u201d Katz said. \u201cItems on site to be shown, but not retail sales.\u201d \u201cNo retail,\u201d confirmed Marconi.
