TWINSBURG -- Residents of Cobblestone and North Pond Lanes may see roadside construction and landscaping near or on their property in spring 2013.
A $1 million reconstruction project for storm drains along Cobblestone and North Pond lanes has been recommended for the city's 2013 engineering projects. City engineer Amy Mohr said it takes a large effort to repair storm drains in a residential area. Due to a gradual calcium buildup, storm runoff pipes along Cobblestone and North Pond lanes have become partially blocked.
Mohr said the concrete drain pipes will be replaced with plastic pipes to prevent similar issues in the future.
"There's reinforced concrete pipe that makes up that storm sewer that's building up a very hard [calcium] coating, kind of like a stalactite, reducing the diameter of the storm sewer system," Mohr said. "We've actually done some sampling... we did some soil investigation testing, and basically it's calcium in the area. We're replacing [the concrete] with HTPE [plastic water pressure] Pipe so we won't have a rebuilding of the growth."
[Calcium] won't attach to plastic."
Estimates place the project's cost at roughly $1 million, including a $499,000 30-year (zero interest) loan from the Ohio Public Works Commission, Mohr said. The other half of the project will be funded immediately through Twinsburg's Capital Improvement Fund. More than 3,000 feet of plastic pipe of various dimensions will be installed during construction.
Perhaps most importantly for residents, the construction will also involve heavy landscaping of yards adjacent to the streets, affecting roughly 70 homes, as work crews will need access to the roadside drains.
"Front yards, side yards ... it's going to make an impact," Mohr said. "There will be a lot of landscaping that will need to be displaced."
Mohr said construction crews will gain access to the drains through the streets and nearby yards. Disruption to underground utilities such as electricity and cable may also occur.
The project is expected to begin in spring 2013 and finish in August of that year, provided the bid is awarded on schedule and construction proceeds smoothly. Mohr does not expect detours for the project, as both affected areas are dead-end residential streets.
"I'm assuming the project's probably going to go through August," Mohr said. "It may even go [longer] than that, depending on the sequencing. We might end up adding another month or so to that schedule."
Councilman Gary Sorace said the material and financial cost of the project is worth improving infrastructure in Twinsburg.
"It's a project we need to go forward with," Sorace said. "Undertaking a project like this, there's going to be some destruction of property along the way. It'll be an inconvenience to people, absolutely, but that's what happens when you make progress."
