The situation on the ground.
Schenectady’s defining water problem is the river. The Mohawk jams with ice most winters, and when a jam releases, the low-lying Stockade takes the water on the breakup, with a warning window measured in hours. The 2018 event, when a seventeen-mile jam formed between Lock 7 at Vischer Ferry and Amsterdam, is the scale this can reach.
River flooding is not a drying job. Floodwater from the Mohawk is Category 3, contaminated by definition, so saturated drywall, insulation, carpet, and pad come out rather than getting dried in place, and the structure is cleaned and sanitized before anything gets rebuilt. Treating river water like a burst pipe is the mistake that makes a flooded building unhealthy for years.
The rest of the city has ordinary water losses in extraordinary buildings. The Stockade is the oldest continuously occupied neighborhood in the region, and pre-1900 structures with stone foundations and dirt or partial-slab cellars hold moisture in ways modern basements do not. Abate Pro dries these buildings to metered readings, on the schedule the masonry sets.
