GOODRICH, Mich. (AP) - The Flint-area community of Goodrich has approved a review to help deal with sinkholes that are increasing in size at a 100-year-old dam.

Officials approved the work by Midland-based Gerace Construction that’s expected to cost more than $40,000, The Flint Journal reported (http://bit.ly/1cs5OWS ). An engineering business, Wade Trim, has been working on a plan to deal with the problem.

“We really need to know what’s there,” said Councilman Pete Morey.

Wade Trim project engineer Jason Kenyon said work will include “exploratory excavation” and some repairs to the concrete walls of the dam. Wade Trim will help Goodrich get a permit for work from the state’s Department of Environmental Quality for the work, which could begin in late April or May.

“Those sinkholes have formed over a rapid rate over the last couple months,” he said. “This is plugging another hole in the bottom of the bucket when there are other holes that need to be filled.”

In 2012, a DEQ report gave the dam a “significant potential hazard” rating. The report found no structural deficiencies Holes previously were patched along the spillway and embankment of the dam, which originally was used for hydroelectric power.

The state wants the village to have short- and long-term plans for the dam.
