The best way to combat flooding in the Frederick Street area isn’t to straighten out the Copper Mine Brook’s meandering channel, as the city has long planned.
Instead, experts who are looking into the problem have determined that replacing the century-old bridge on Frederick Street would do more to relieve flooding.
As a result, city councilors recently backed a contractual change with the Cheshire-based Milone & MacBroom engineering consulting firm to switch its attention from redesigning the stream channel to coming up with a plan for a new bridge.
The Frederick Street Bridge is one of a dozen Connecticut spans that’s been rated in “criticial” condition and was closed for a month in 2007 for emergency repairs on its foundation so officials have long expected they would replace it.
Now, though, they’ve learned that putting up a wider, slightly higher span in its place is also the best thing they can do to combat flooding on the lower section of the Copper Mine Brook, which has had several serious floods in the past five years.
Large sections of the creek and its tributaries overflow during heavy rains, inundating basements, washing over streets and causing significant damage. Frederick Street has had to be evacuated at times because of the quantity of water.
Realigning the S-curve just north of the bridge, as the city had anticipated it would try, would not help with flooding and might even raise the water level behind the bridge, according to a January memorandum from Milone & MacBroom to a city engineer.
It isn’t clear just how much a new bridge would help with flood control either, but the consultants said it should provide some benefit.
However, they added in the memo, “the effectiveness of anything done at the crossing itself will be limited due to the tailwater effects of the Pequabuck River” just downstream.
What happens, in a nutshell, is that water pouring down the Copper Mine Brook during heavy rains runs smack into a swollen Pequabuck near Theis Precision Steel and begins to back up across Frederick Street and into homes.
There are many complicating factors, from poorly placed drains to small berms, but the problem that fundamentally afflicts the low-lying area is that there is nowhere for the water to go.
The change in the contract with Milone & MacBroom won’t cost taxpayers anything extra because it’s doing the same amount of work, just on something different than expected.
The firm is receiving more than $200,000 to study flood relief measures along the length of the brook. It issued a preliminary report several months ago.

$200,000 to tell us what kind of bridge we will need, and it might not even solve the problem after spending another million to build it?
The $200K was allocated to find ways to alleviate flooding in several parts of town along that stream, not just Frederick Street.
The other thing is that everybody realizes the bridge needs to be replaced before long anyway. The one that's there is not adequate.
The city already replaced a similiar bridge on Artisan Street a few years back for much the same reason.
Perhaps the boneheads who bellyache about money spent maintaining or improving our City would rather wait until the bridge collapses and the flood waters rise high enough to soak their butts before we fix it?
This study is the result of Mayor Storts's rejuvenation of thelood Conbtrol Committee after all the water problems experienced in the area the previous years.
"The other thing is that everybody realizes the bridge needs to be replaced before long anyway" said Collins.
When did you receive your civil engineering degree Steve? There's nothing wrong with that bridge. This would be just an excuse for Democrat politicians (as usual) to fill the pockets of their contributors.
It is 100 years old, undersized and one of a dozen "critical" bridges in Connecticut. It doesn't take a civil engineering degree to know it's not long for this world.
Wards solution was "give em sandbags".
With all the money we pay Millone and MCbroom, we should just buy the company, it's probably cheaper.
4:38 ~ Looks like he's taking the bull by the horns now. Go Ward!

The bridge replacement is the result of action taken BEFORE Ward became mayor.
Fo him to take credit would not be surprising, but it would be dishonest.
1:43 a.k.a. credit police,
Whether or not the work was started before, it's up to the present Mayor to get er done!
