Turkey Brook Drainage Improvement Project —
The upper reach of Turkey Brook flows through Oakville, an urban neighborhood of Watertown, CT. The gradual urbanization of the watershed over the past 50 years resulted in frequent and devastating flooding to homes and businesses located in the low-lying areas adjacent to Turkey Brook. In response to this flooding, the Town of Watertown retained LEI to conduct street line and topographic surveys, study the hydrology and hydraulics of existing and proposed conditions, prepare design plans, procure land-use permits, prepare contract documents, and provide construction engineering services for this significant stream channel improvement project.
The project involved over 3,000 feet of channel widening, lining, and fishery accommodations, property acquisition, replacement of hydraulic structures and utilities at four roadway crossings and landscape enhancements. Restoration measures included vegetative gabions, flow deflectors and turf reinforcement mat.
LEI designed a majority of the project in the traditional design-bid-build format, although several design/build components (roadway culverts and related utility relocations) were embedded within the contract. Construction was completed ahead of schedule and below the bid price.
