The intersection of Duncan Avenue and Route 8 opened on Oct. 4 -- about one month late -- after having been closed since April so that the small bridge over Gourdhead Run creek could be replaced by a concrete culvert structure.
Hampton council president Victor Son said the project was delayed for a month due to a design flaw in the concrete culvert, which had to be remade by the manufacturer.
Funded by the county and state, the $798,000 culvert project is part of the Duncan Avenue Improvements Project Phase I, which includes the dry basin retention pond and the addition of turning lanes on Duncan.
The work has been managed by the Pennsylvania Department of Transportation and performed by Gary Metzger Cement Contractors.
Mr. Son said the contractor is finishing work on the dry basin, which includes grading, seeding the area with grass and installing trees. He noted that during some recent rainstorms, the basin functioned as designed, storing water to reduce downstream water impact.
"We have heard from our neighboring municipalities downstream that they've noticed there was less water during big storms as a result of that basin," Mr. Son said.
Next spring, PennDOT will work with the township to complete the highway portion of the project by adding a turning lane on Duncan and on turning lanes on Route 8 in both directions. Also, they'll be adding a walking track around the dry basin. No road closures are planned.
In December 2008, the township paid $285,000 for property at the confluence of Gourdhead Run Run and Little Pine Creek, which is part of the Pine Creek Watershed. The site was flooded by Hurricane Ivan in September 2004, and the area had suffered stormwater management problems in the past, which often caused flooding downstream in Shaler and Etna.
Hampton also has plans to construct a permanent lake on Pine Creek, once it receives additional grant money.
Mr. Son said a master plan for flood mitigation developed five years ago called for the final phase to involve a small lake just south of Duncan behind the houses that were destroyed during Hurricane Ivan.
The plan, estimated to cost $10 million, would control the disbursement of water downstream through a valve system.
