Ahead of the Storm (AOTS)

Ahead of the Storm (AOTS) grew out of a group of citizens from Charlotte, Hinesburg, and Shelburne who were concerned about the serious decline of Lake Champlain’s health and water quality. Stormwater runoff from driveways, fields, parking areas, and lawns is a major factor in the deterioration of our water quality. AOTS helps communities change the way stormwater is managed on properties to reduce water pollution and be more prepared for extreme weather events and impacts of climate change. Fifteen municipal, commercial, and private properties have been selected to become demonstration sites to showcase more optimal conservation practices in a variety of landscape settings.

Geomorphic Assessments and River Corridor Planning

The references below contain Vermont stream geomorphic assessment data that describes channel characteristics and sensitivity to change - how likely excessive channel erosion or deposition, or a sudden change in flow path, will take place during a flood. River corridor plans have also been prepared that interpret the geomorphic data and identify priority projects.

Don’t Flush It!

This campaign by Green Mountain Water Environment Association informs Vermont households about how to reduce their outputs of ecosystem-damaging chemicals/materials and how to dispose of them properly.

CLOGGERS!" is a guide to knowing what NOT to flush, pour, or spill into your private septic tank or municipal sewer system -- fats, oils, greases, and various paper and plastic materials that clog pipes and impair system performance.

DRUGS!" details the harmful impacts on both human and ecosystem health of flushing or pouring out medications of any kind, and provides advice for safe disposal. It also notes the risks of personal care products and suggests ways people can minimize their water pollution impact.

LAWN & GARDEN POISONS!” suggests easy ways Vermonters can cut their use of pesticides and chemical fertilizers that run off into waterways and cause environmental damage (and endanger human health).

"HOUSE & GARAGE HAZARDS!" cautions Vermonters about typical household substances such as cleansers, polishes, paints, and solvents, as well as auto products like gasoline, oil, antifreeze, and wax. All will ruin septic systems and sewer facilities if poured or flushed, and will poison surface waters and wells if spilled in  driveways, soil, or storm drains. The brochure offers recipes for safe, effective, homemade cleansers and disinfectants, and provides comprehensive disposal options.
