Title
Approving temporary construction work with associated noise impacts between the hours of 7:00 PM and 7:00 AM for work associated with Madison Metropolitan Sewerage District Northeast Interceptor Joint Grouting MH10-106 to MH10-101. (15th AD)

The Madison Metropolitan Sewerage District (MMSD) Northeast Interceptor Joint Grouting MH10-106 to MH10-101 project intends to rehabilitate approximately 2,400 linear feet of 48-inch diameter sanitary sewer between the intersection of Highway 30/51 to Regas Road along the City's Marsh View Bike Path. Evening and early morning work will be required to take advantage of low flow levels in the sewer in the off-hours. This work does not allow for all construction activities of the project to take place during the normal working hours of 7:00AM and 7:00PM.

The proposed activities beyond the hours of 7:00 AM to 7:00 PM may be as follows:
1. Access to manhole structures, including televising & cleaning and joint grouting.
Construction activities generally exceed the noise limits imposed by the Madison General Ordinances and temporary construction activity between the hours of 7:00 AM to 7:00 PM is allowed to excee...
