Concord task force unanimously approves Warner’s Pond bathymetric survey and sediment sampling
Summary
The Warner’s Pond Task Force authorized a bathymetric survey and additional sediment sampling this spring, approving a not-to-exceed amount of $20,600 to update current depth and sediment data for future planning.
The Town of Concord Warner’s Pond Task Force voted unanimously to authorize a bathymetric survey and additional sediment sampling of Warner’s Pond, approving funding for the work to be scheduled in May.
Task force member Chris (task force member) reported that the company that provided an earlier estimate was available the week of May 19 and that the previous quote had risen from about $15,000 to roughly $18,186; he said the data would inform dredging, dam‑removal and ongoing pond‑management options. "So it was 15. Now it's 18," Chris said when members discussed the updated price.
Town staff confirmed the consultant could perform bathymetry (sonar depth mapping) and also add sediment sampling and laboratory analysis for a small additional fee; staff recommended budgeting $20,600 to cover the scope and processing. Members moved to proceed and then conducted a roll‑call vote. The motion passed unanimously: Paul (yes); Malcolm Bryant (yes); Jeff Collins (yes); Christine Denaro (yes); Keith Hannon (yes); Mark Howell (yes); Bill Cammaza (yes); Liz Morrison Howe (yes); Sven Weber (yes); and others voting yes during roll call.
Members discussed timing and technical detail; staff noted the survey measures water depth to the top of sediment using sonar and that sediment coring for additional analysis could be done while the team is on site. Several members said spring conditions made scheduling now preferable to waiting. The task force asked staff to proceed with contracting and scheduling and to include processed deliverables (maps and data) to support the task force’s deliberations.
No legal approvals or permits were required to authorize the survey; the task force’s action was a planning/data appropriation rather than a construction authorization.
