Weekly Street Sweeping

During the months of December and January, street sweeping happens weekly instead of biweekly to tackle the increase of leaves and other wind-blown debris on Diamond Bar city roads.

Increasing street sweeping frequency during the rainy season also helps reduce the potential for flooding to occur as a result of clogged storm drains.

Residents are asked to help ensure the effectiveness of the City’s street sweeping program by remembering to keep their vehicles off of streets scheduled for sweeping during the designated hours posted on the no-parking signs.
