Humboldt Sewer Repair Project Update: June 16, 2017

Humboldt Sewer Repair Project Update: June 16, 2017


Concrete street restoration on North Maryland Avenue between Ainsworth and Jarrett streets will continue in phases until complete.

  • Preparation for concrete street restoration is currently scheduled to occur Mondays and Tuesdays over the next few weeks. This work may be postponed due to weather or subcontractor availability and rescheduled on short notice.
  • During each phase, crews will remove temporary asphalt patches and restore the trenches with concrete. Once the concrete is poured, it will take up to seven days to harden to the required strength for car and truck traffic.
  • Due to the scope of concrete restoration there will be no street or driveway access from 7:00 a.m. to 6:00 p.m. during preparation for concrete restoration and during concrete pouring. In addition, there will be limited local access only while the concrete hardens.

Crews will continue spot repairs, cleanout installation, and lateral sewer pipe construction in multiple locations.

  • These smaller phases are being completed to prepare for Cured in Place Pipe Lining (CIPP) sewer repairs this summer.
  • The contractor will apply temporary pavement to all areas excavated for sewer construction. Final trench paving and concrete restoration work throughout the project area will occur as crews become available.


The map posted at shows the anticipated construction locations through June 30. Please be aware that schedules are subject to change due to a variety of factors, including conditions underground, weather, traffic impacts and subcontractor and materials availability.

Residents and businesses should expect periods of inactivity between each phase, ranging from a few days to a few weeks. The duration depends on a variety of variables including underground conditions, weather, traffic impacts, subcontractor schedules, quality control tests and availability of materials.
