Peak flows had scoured the original stormwater management swale at the FedEx facility
New detention pond was constructed and lined with grouted standard riprap to protect the outfall
Swale was constructed and extended to connect to the existing stormwater outfall
Coventry Lake Dam Improvements, Coventry, CT
We completed the construction of a new lake dam and gate control structure for Coventry Lake. The project involved constructing a temporary coffer dam and a 24” bypass system while a new inlet structure and low-level gatehouse was built. The main inlet channel was cut back, and a new radius concrete head wall was poured in place. The current gatehouse was demolished and replaced with a manhole and a section of 42" concrete pipe to tie into the existing outlet.

Demolition
Coffer dam installation
Grading
Installation of 24” DIP + Valve and Gate Chamber Structure
Erosion/sediment control
Excavating and backfill for precast concrete, spillway, training walls, pipe headwalls, and bridge footings
