Derby Fishing Platform

Project Type: Assessment

Activities: Phase I Environmental Assessment with compilation of past-user interviews

O’Sullivan’s Island is a peninsula at the confluence of the Housatonic and Naugatuck Rivers, located south of Derby’s downtown commercial district. While vehicles and trains pass nearby, the site offers a welcome moment of quiet among trees along the waterfront. Enveloped by structure, water, and sky, O’Sullivan’s Island is one of the most interesting and naturally beautiful pieces of land in the lower Naugatuck Valley. It is also one of the most challenging brownfield locations NVCOG has had the opportunity to improve.

Over the last decade, NVCOG’s Environmental Planner Arthur Bogen and Executive Director Rick Dunne have been significant players in the orchestration of funding contributions and work completed by the City of Derby and the Connecticut Department of Economic and Community Development. O’Sullivan’s Island Recreation Park opened to the public for the first time in over twenty years in 2009. In 2013 the City of Derby completed its portion of the Naugatuck River Greenway trail that runs across the site’s northern edge.

NVCOG was awarded a $200,000 DECD grant to conduct environmental assessments and develop remediation strategies on the site.

Main Street South in Derby

Project Type: Assessment

Activities: Environmental Site Assessments on 4 parcels. ( 2 Factory Street, 23 Factory Street, 90 Main Street, and 0 Water Street)

The City of Derby received multiple inquiries from private parties regarding city-owned parcels south of Main Street. These parcels have long been part of Derby’s central design district and are approved for high-density, mixed-use development. The City requested NVCOG apply on its behalf for funding through the Connecticut Department of Economic and Community Development’s (CT DECD) Municipal Grant Program.

NVCOG was awarded $200,000 to conduct assessment activities in the Derby Main Street South project area. Environmental assessment activities will support the construction of local roads in the area and will target parcels most ready for development. The assessment project is critical to the success of the City of Derby’s $5 million Urban Act grant, which will directly fund construction of local roads and infrastructure.

Project Status: A Request for Proposals (RFP) for a Licensed Environmental Professional (LEP) for assessment services was sent to NVCOG’s  pre-qualified short list. Five proposals received. The RBP Project Selection Committee invited Arcadis to enter contract negotiations.

 To date, Arcadis has produced:

  • 2 Factory Street – Phase I, Phase II, and Hazardous Building Material Survey
  • 23 Factory Street – Phase I, Phase II, and Hazardous Building Material Survey
  • 90 Main Street – Phase I and Hazardous Building Material Survey
  • 0 Water Street – Phase I
