Project Summary

This project represented the largest permitted tidal wetlands filling and mitigation project in the state of Connecticut in the past ten years. Hoyle, Tanner was retained to provide permitting, design, and construction administration services for a new parallel taxiway access to Runway 2, and bring both primary runway safety areas at Tweed New Haven Regional Airport into compliance,. Permitting services included filing state permits for watercourse realignment, industrial dewatering, individual NPDES permit, tidal and inland wetlands filling, and federal permits for dredging and filling. The mitigation for the approximate nine acres of wetlands filling included approximately 56 acres of wetlands restoration and creation. The restoration program included harvesting phragmite inundated tidal wetlands and raising salinity levels in these areas through hydraulic watershed control measures.

Project highlights for the entire Runway Safety Area Enhancement program include the realignment of Morris Creek, excavation, dewatering, and handling of approximately 80,000 cubic yards of clay and organic peat material, treatment of approximately 27,000 cubic yards of clay with Cement Kiln Dust to create suitable subbase material, design of a temporary bridge, new tide gates, a water level sensor control system, re-alignment of Dodge Ave, and all associated utilities, and replacement and upgrade of the existing FAA localizer and Approach Lighting System.
