Retaining‑wall repairs, tree replacements and monitoring wells remain as Pazen Valley school closeout continues, project team says

Project staff reviewed outstanding punch‑list items for the Pazen Valley elementary school during the Planning/Building Commission meeting on July 8, saying most issues are being tracked and several will be closed once the town inspects completed work.

The presenter said a multi‑page letter from town staff and a November 2024 structural‑engineer letter from DRA guided much of the review. "It's our opinion that the observed cracking was most likely associated with volumetric changes in the concrete," the presenter said, summarizing DRA's view that the hairline cracks are caused by temperature and drying shrinkage and "do not indicate a structural deficiency." The presenter and staff agreed the cracking appears largely aesthetic but noted water intrusion from the backside of the wall is the maintenance concern.

Why it matters: commissioners pressed whether the town or the contractor should bear repair costs and whether surface repairs would be durable. Staff said the original concrete contractor was bought out and current third‑party proposals included two remedies: an injection‑grout approach recommended by a manufacturer representative (roughly $100,000) and a less‑invasive remediation that would expose the wall backside, waterproof it and use a lower‑cost front‑face repair (about half the higher figure). "They didn't feel comfortable just filling the cracks with epoxy," an agency official said, explaining some contractors decline to warranty surface‑only fixes because water can work epoxy out over time.

Site and environmental items: staff reported wetlands‑planting receipts and much of the debris/outlet‑pipe cleanup have been completed and closed. Several monitoring‑well casings remain exposed; the presenter said town practice is to either abandon wells in place and cut below grade or have the geotechnical firm remove or cap them. "There's a steel casing protecting the actual PVC pipe — we can cut it down, cap it and cover it with topsoil," the presenter said.

Landscaping and trees: town staff asked the project team to replace additional trees after a markup review. The presenter counted six on his markup but said town staff identified roughly 15–16 trees for replacement. Commissioners and staff discussed whether the town would assume watering and maintenance responsibility after turnover; the presenter said that should be clarified at final sign‑off.

Drainage and basin performance: staff showed photos of the southwest detention basin and riprap outfall, noting the basin is well vegetated and performed during recent rains. The presenter recommended a modest riprap augmentation to prevent localized rutting rather than a large invasive regrade; an agency official said the contractor is willing to add riprap this summer and Gilbane has requested an engineer assessment of one catch basin whose slope appears steeper than its design.

Costs, documentation and next steps: commissioners urged clearer turnover sign‑offs to avoid multi‑year open items; staff acknowledged documentation could have been stronger. The presenter said the team will forward contractor recommendations and proposals to DRA and request the engineer's comment before proceeding. Remaining scheduled work includes sidewalk removals tied to an earlier change order, which staff said will be completed by the end of the week.

Formal actions at the meeting: the commission approved the minutes from May 13, 2026, after a motion and second; later the commission moved and seconded to adjourn, with 'ayes' recorded on both votes.

What comes next: staff will send the contractor proposals to DRA for review, follow up on the monitoring‑well caps, obtain quotes for tree replacement and coordinate the limited riprap work with the town engineer; no additional formal vote was recorded on repair funding at the meeting.
