Residents along Old Capitol Trail may see some action taken against reports of flooding during periods of heavy rain.
On Tuesday afternoon, the New Castle County Council's special services committee voted 7-0 to approve work on the Kirkwood Library, in the 6000 block of the Kirkwood Highway.
Tony Schiazi, of the county's special services division, said that a number of residents along the 6000 block of Old Capitol Trail complained of excessive flooding, which he said many attributed to the construction of the nearby library.
The repairs from the county side – roughly $100,000 – will come from the flood mitigation account, requiring the special services committee to sign off on the project, Schiazi said.
By using in-house crews, he added, that amount could be "a lot less."
Dave Athey, of Duffield Associates, said that a series of three-inch pipes that run beneath a sidewalk are a likely cause of some of the flooding, which crosses the center line of Old Capitol Trail in times of heavy rainfall.
A 42-inch pipe and a nearby bioretension basin, Athey said, appear to be working as expected, adding that they would continue to monitor the pipe in periods of heavy precipitation.
Athey said that a video shot by a resident during last August's heavy rainfall was "alarming."
The pipes, and any other onsite repairs are the county's responsibility, Schiazi said, while grading improvements to Old Capitol Trail fall under DelDOT's control.
Councilmember John Cartier, 8th District, said that, having grown up in that area, he's observed that ponding has always been a problem along that portion of Old Capitol Trail.
"And that is DelDOT's problem," he said.
According to Athey, DelDOT's cost for grading to alleviate flooding on Old Capitol Trail is roughly $120,000.
