The Town’s storm system manages rainfall and includes storm lines, mains, ponds, and outfalls.
Rainfall that does not soak into the ground flows as runoff into storm drains (catch basins), carrying any residue with it. Stormwater is not treated — it empties directly into local waterways.

Roof cleaning and moss treatment products can runoff your property and enter storm drains.
The Town does not endorse any specific cleaning or treatment products.
Recommended cleaning methods are:
- Asphalt, cedar, and untreated wood shingles: Clean using plain water or water with a non-hazardous cleaning solution.
- Treated wood shingles: Dry wash only, as these materials contain toxic preservatives.
