Greenburgh officials say East Hartsdale sewer repair is deep, costly and may require road closures

The Town of Greenburgh told residents at its Sept. 10 work session that a significant sewer repair on East Hartsdale Avenue will be complex, prolonged and expensive.

Commissioner/comptroller (S9) said engineers are actively evaluating the issue and emphasized the project’s technical challenges: the hole is about 35 feet deep and adjacent to multiple utilities and buildings, requiring specialized contractors. "It is very intricate," S9 said, adding that the town wants to "do it once, and then we leave it in the best condition possible." Chair S1 told members he had heard a shoring estimate "could be about 2 and a half million dollars." S9 confirmed the project is costly and staff are consulting several engineering firms to select the right approach.

S9 said staff have been in contact with building owners and plan additional meetings with residents this week to address sidewalk concerns and other impacts; the town also committed to relaying updates first to the board and then to residents. Board members asked staff to provide timeline updates whenever possible, including advance notice if road closures or detours will affect commuter access to the train station.

Why it matters: The depth and location of the repair create safety and logistical complications, possible detours for commuters, and a sizeable fiscal impact for capital work and shoring. The board emphasized prioritizing safety and doing the engineering work correctly rather than rushing repairs.

What’s next: Engineers will continue evaluation, staff will meet with residents and the board will be updated as plans and cost estimates solidify. No formal contract award or vote was recorded in the provided excerpt.
