On Monday, July 13, the City will have its Large Brush Collection day.
Branches over 3 inches in diameter and up to 15 feet long are collected on this day if placed at the curb in front of your house by 6:30 a.m.
Large brush should be stacked, unbound, in one row along the curb with the cut ends facing the street. The row should be no more than 15 feet long and four feet high. Anything beyond this amount will not be collected unless you have made prior arrangements to pay additional fees.
