Street sweeping is an integral part of street maintenance operations. Some of the objectives of street sweeping are: improving safety, preventing materials from entering the stormwater drainage systems and providing a clean appearance for residents and visiting public.
Streets are continually subject to dust and dirt from residential/commercial construction, blown in by wind or tracked by vehicles, from fallen leaves and other debris. The sweepers have a high dump hopper that utilizes a hydraulic lift to dump the debris into a dump truck. The dump trucks then deposit the debris into appropriate holding areas throughout the City, which eventually are transported to the landfill.
The residential streets are swept seasonally, three times a year. These are conducted in the spring, summer, and fall. Weather and temperature impact the start and end dates. The order of residential areas swept differ annually, so the last area swept one year, may be the first swept the following year.
The City is divided into grids, called "Districts". Each district is then divided into four sections. These sections are then numbered on a map.
The actual sweeping pattern shown runs north and south. North of 'O', this Fall begins with Districts 5, 9, 8, 4, 3, 7, 6, 2 and 1. Simultaneously, South of 'O', this Fall we begin in Districts 18, 17, 14, 15, 16, 13, 12, 11, and 10. The sweepers always begin with section A and work through section D.
The map shows residential routes the street sweepers are following this season, as well as which residential areas have been completed.
