The City Council on Tuesday agreed to terms of a $1 million federal grant to study upgrades to the East Ditch’s 100-year-old infrastructure and stop the flooding that damages properties, closes roads and traps people in buildings. The East Ditch upgrade, which could cost as much as $80 million, is not to be confused with another federally funded flood control study of the city’s so-called upper Still River corridor – from Rose Street to Lake Kenosia on the west side. That upper Still River corridor study, funded by the Army Corps of Engineers, will look at ways to align snarls in the Still River to improve its hydraulics, because impediments in the river’s flow causes water to flood over its banks. In the downtown’s East Ditch, a drainage area from south Main Street to South Street, and from Main Street to Town Hill Avenue, including Keeler Street, Center Street, State Street and Park Place, the hope is to document a concrete plan to upgrade a drainage system that Iadarola called “substantially undersized.”
