The Department of Public Works' curbside leaf collection is underway and will continue through Dec. 1.

The town asks, however, that residents consider backyard composting and suggests that they contact the Conservation Department at 203-341-1170 or Earthplace at 203-227-7253 for information.

Leaves placed at the curb in biodegradable paper bags will be collected. Plastic bags can't be used because they are not compatible with the composting process.

DPW crews will pick up throughout town several times during the collection period, with a final one-week pass starting on Dec. 1. Residents living on private roadways must place their bagged leaves at an intersecting town roadway.

Residents with a valid WP sticker on their vehicle may take leaves to the yard waste site at 180 Bayberry Lane, which is open Monday through Friday from 7 a.m. to 3 p.m. and 7 a.m. to noon on Saturday. From Saturday, Nov. 8, through Dec. 6, the Saturday hours will be extended to 3 p.m.

Residents whose vehicles display a valid sticker may deliver as many as six 30-gallon bags or containers of leaves without a fee. Exceeding that will incur a $30 per-load fee. Vehicles larger than a conventional pickup with a 4-foot-by-8-foot bed will be charged $80 per ton.

Dump tickets to cover the costs must be purchased at Town Hall, Monday through Friday between 8:30 a.m. and 4:30 p.m. or by writing to the Department of Public Works, 110 Myrtle Ave., Westport CT 06880.
