About a dozen residents attended a public meeting held by Public Works officials last night at St. Patrick’s Manor, to update the town on the Central Street Siphon/Sudbury River Interceptor Project and several other projects the town will be working on this construction season.

Department of Public Works Chief Bill Sedewitz said there are lots of projects the town is working on because, “the town went for decades without maintenance or updates on its infrastructures.”

Over the next 25 years, Framingham will be spending about $1.5 million a year on its infrastructures to “catch up,” Sedewitz added.

Along with new requirements set by the Massachusetts Water Resources Authority and the Massachusetts Department of Environmental Protection, Sedewitz said the goal is to complete these projects with the least impact on the residents.

A few anticipated Public Works construction projects for 2011 included Broderick Drive water main replacement, Pleasant Street water pump station improvements, and South Concord Street roadway restoration.

The first phase of the Central Street Siphon/Sudbury River Interceptor Project, relining the long sewer pipes along the Sudbury River to Route 9 was completed last year, according to Framingham’s Project Manager Katherine Weeks.

The pipes were about 60 years old and “were not in the best shape,” Weeks said.

The second phase, which is scheduled to begin mid-April, involves creating a new line for the sewer pipes along Edgell Road, Auburn Street, Auburn Street Extension, and Beulah Street to the nearby water pumping station.

The pipeline for the sewer path must be 25 feet below the ground, which has caused a delay in the schedule because rock had to be excavated to put the pipe that deep, Weeks said.

Resident and business owner Jennifer Porter said she has gone to a lot of the meetings and thinks the town is doing a good job keeping people up to date.

Porter owns River’s Edge Greenhouse located on Auburn Street Extension, where construction is estimated to begin around April 15.

“The scariest thing is that is when we open,” Porter said. “All there will be is equipment around.”

Framingham’s Director of Capital Construction Management Paul Scott said the town is working with the contractor and residents to make the town’s projects get done seamlessly.

The town has created a Web site for the construction projects, where residents can sign up for alerts via e-mail, Scott said. The Web site is www.BuildingFramingham.com

“An e-mail blast will be sent out as soon as possible regarding impacts on traffic or any disruption of services,” he added. “This will help people plan their day a little better.

Scott also encouraged residents to call to inform the Public Works Department about any problems that are going on because of the construction. The number is 508-532-6040.

Ron and Marci Handverger asked about another water pipe project started on Prospect Street last year, that has not been finished yet.

“(The project) made a mess of our backyard,” Ron Handverger said.

Sedewitz said the Prospect Street project will be finished but with a stimulus grant the town received the Central Street Siphon/Sudbury River Interceptor Project took priority.

“Our intent is to finish the project,” Sedewitz said. “First we deal with the utilities, then we let the ground sit and settle for a bit, and then we do the roads.”

“Once traffic impact won’t mix with Prospect Street we will get it done,” Sedewitz added.

The Prospect Street and the Central Street Siphon/Sudbury River Intercceptor projects are both estimated to be finished by spring 2012.

Another public meeting for upcoming Framingham construction projects will be held on March 16 at 7 p.m. at the Hemenway Elementary School.
