Representatives for FD 120 Turnpike LLC updated the Southborough Conservation Commission on Feb. 13 about a proposed 60-unit apartment building at 120 Turnpike Road and asked the commission to continue technical review of the Wetlands Protection Act notice of intent.

Brian Charleville, chief operating officer and general counsel for the Ferris Companies, said the project won a comprehensive permit from the Zoning Board of Appeals in December and the recorded decision will allow the team to move forward with conservation reviews. Charleville and the project team said they revised the project layout during ZBA review to move the building north, away from a mid-slope wetland, and to avoid relocating a green-sand filter and other infrastructure features that otherwise would have intruded into wetland buffers.

Goddard Consulting wetland project manager Mitch Maslanka and civil engineer James Tetro presented site plans showing existing resource areas, drainage swales, and two man-made ponds constructed in the 1980s. The applicant proposed to fill a small isolated vegetated wetland (about 410 square feet) and to create a replication area of about 838 square feet on nearby upland due to soils and access suitability. Maslanka said the replication site contains invasive shrubs and had soils that showed signs of prolonged saturation between 1 and 2 feet below the surface.

Commission members asked for additional information on the proposed land donation the applicant referenced; staff said specifics would be shared later and that the commission’s role is to review the Wetlands Protection Act application and provide recommendations where appropriate. The commission and staff agreed to continue the hearing to March 6 so the commission’s wetland scientist and peer reviewers can complete their reviews and the applicant can provide revised materials.
