WESTPORT — After a two-year saga fighting mold strung along while students remained in class, Coleytown Middle School will now be shuttered for the remainder of the year.

The relocation of 450 Coleytown students grades six through eight first appeared to be a temporary fix but has now become a permanent solution, according to officials.

“The way I see it there are multiple challenges, structural challenges, with that building, even more than we realized. We knew there were some challenges but there are even more, and they’re even more significant than we had realized,” Board of Education member Elaine Witney said in reference to preliminary reports that revealed the extent of work needed to remediate Coleytown.

Whitney, along with her six other school board members, voted unanimously to keep Coleytown sixth- and seventh-graders at Bedford Middle School and the school’s eighth-graders at Staples High School for the duration of the school year.

“Roof and facade leaks are allowing water into the building envelope — where it doesn’t belong. Water entering the envelope is causing deterioration, and it’s allowing algae and moss to grow on (and perhaps inside) the facade and roof,” Thomas Olam, president of Watsky Associates, a Valhalla, New York-based engineering consulting firm, wrote about the state of Coleytown in a report dated Oct. 4.

A congruent preliminary report from the Mount Kisco architectural engineering firm KG+D confirmed the significant structural damage at Coleytown due to extensive water saturation and moisture at the school.

“I just don’t want to risk that if we move them back in, we’d have to move them out again. That to me would be devastating,” Superintendent Colleen Palmer said noting the severity of Coleytown’s structural deficiencies would likely pose health and safety hazards throughout the year that could prompt another school evacuation.

“I think the best thing we can do for the kids and the parents at large is take the uncertainty out,” board member Vik Muktavaram said, adding a definitive answer on whether Coleytown’s students will return to the Coleytown campus this year will allow the board to put full attention toward constructing a permanent fix for the school.

To date, the district has spent $684,568.64 on expenses related to Coleytown remediation and that number is expected to climb to over 800,000, Westport schools Chief Financial Officer Elio Longo said.

To accommodate the 300 Coleytown sixth- and seventh-graders at Bedford, the board plans to rent six new portable classrooms that will likely not be set up for another two months, Palmer said. A new class schedule will be implemented at Bedford to alleviate overcrowding and at Staples, the eighth-grade students who have been quarantined to a hallway of eight classrooms will be given more freedom to walk around the school in order to make the at-first temporary fix more comfortable for the Coleytown students until the school year ends in June.
