After three lengthy public hearings of the Environmental Protection Committee regarding one portion of the Intervale drainage project, deliberation among the committee members is finally set to take place in November.

The application in front of the EPC is for the installation of a 2-by-6-foot cement box culvert at 95 Rose Lane that would empty into the Noroton River.

Following a public hearing in August, the EPC asked town engineers to go back to the drawing board to determine if any alternatives to the proposed project existed.

They do, but at a hefty price.

The Intervale drainage project includes the installation of wider pipes leading toward the Noroton River to alleviate flooding problems. The wider drainage pipes will allow the water to flow faster toward the final desired location in the Noroton River.

The project will cost an estimated $1.5 million and take approximately seven to nine months to complete. The construction costs of the project are roughly $1.27 million with an additional $300,000 for administrative costs, which include project oversight, fees and inspections.

Each of the four proposed alternatives are more expensive and would add, at a minimum, 60 days to the project. Two of the four add 14 to 17 months because of the need to receive permits from the state Department of Energy and Environmental Protection.

"We still believe our original plan is the best one," Darren Oustafine, assistant director of public works, said at the public hearing.

Joe Canas, an engineer with Tighe and Bond, explained each of the other alternatives.

The first would add an additional 60 days of construction and would cost $1,675,000. It would disturb 100 square feet of wetlands.

The second would add 60 days of construction and would cost $1,669,000. It would disturb 300 square feet of wetlands.

The first and second alternatives would require raising the roadway to accommodate the proposed larger pipes.

The third alternative would cost $1,854,000 but would add a significant amount of time to the project because additional permits from the DEEP would be required. Canas estimated 14 to 17 months of construction time. The project would use Park Lane and West Avenue instead of proceeding down Holmes Avenue to West Avenue. The water would discharge to the Noroton River south of the West Avenue bridge over the Noroton River. This alternative would tie into the proposed West Avenue drainage project, which has not been come before or approved by the Representative Town Meeting yet.

Much like the third, the fourth alternative would tie into the potential West Avenue project and would add a significant amount of time. Canas estimated that the fourth alternative would add 14 to 17 months of time to acquire DEEP permits and would cost $1,758,000.

Canas told the EPC that the permits that would be required for the third and fourth alternatives take between nine and 12 months to acquire.

All of the proposals would require more than $10,000 for engineering costs, and all but the third alternative would require the town to acquire more easements to complete the projects.; 203-330-6583; @Meg_DarienNews
