District facilities staff told the committee April 29 that a report of sewer bubbling on the front lawn of the high school on April 15 led crews to investigate and clear the line. Crews found that a manhole ring had dislodged from the brickwork and tree roots had clogged part of the pipe running from the site to the street.

Facilities staff said the clogged pipe caused a slow leak onto the lawn; there was no sewage backup into the building. A contractor camera-inspected the line and confirmed roots in the older clay section running under the trees; the section closer to the building had been replaced previously with PVC. Staff said the city will add the line to a preventive maintenance program and will raise the manhole to grade to avoid future digging and reduce repeat disruption.

Facilities staff thanked the Department of Public Services crew and noted no damage to the trees is expected. The area is temporarily fenced while the district and DPS coordinate the final repairs.

No formal committee action was taken; the update advised the committee of the repair status and next steps.
