Larchmont Area Sanitary Sewer Improvements (LASSI) Program

Body

--Pile Driving Notice--

 

HRSD, your regional wastewater treatment utility, has begun a project in your neighborhood to replace the existing HRSD Magnolia Pump Station that is nearing the end of its useful life. This replacement project will improve the system’s performance and ensure continued, reliable sewer service in the future. This work should take place primarily between the hours of 7 a.m. to 5 p.m., Monday – Friday.

Construction Update:

  • Beginning as early as February 21st, equipment for sheet pile driving efforts will arrive at the new pump station site at 1101 Magnolia Avenue with the delivery of a crane and sheet piles.
  • There will be a partial lane closure of the southbound lane of Monroe Place as material deliveries are received. Additionally, the sidewalk on the southeast corner of Monroe Place and Magnolia Avenue will be closed around the site perimeter during the project’s timeframe.
  • This work will involve the driving of sheet piles into the ground to create temporary retaining walls that hold back soil to allow for deeper excavation that is necessary for the pump station construction.
  • Our contractors will be using a new method of driving the sheets into the soil that is expected to minimize vibration and noise, but some noise can be expected.
  • To protect nearby residences during sheet piling, vibration monitors will be located onsite and near construction areas to minimize disruption. Alerts are provided to the contractor if the vibrations reach a particular level, and work will be stopped if these vibrations exceed federally established levels that may cause damage to residential structures.
  • Your water and sewer service will not be disrupted.
  • Sheet pile driving work is expected to be completed in 4-5 weeks.
  • The new Magnolia Pump Station is anticipated to be completed within 2 years. Due to the nature of construction, work is weather and situation dependent, and dates are subject to change or be extended.

 

While our project team works diligently to minimize impacts, you may notice increased noise and traffic, along with the people and heavy equipment (with back-up safety alarms) associated with construction. Please take care when traveling around the construction area and for your safety, do not enter the site. Due to the nature of construction, work is weather and situation dependent, and dates are subject to change.
