Miles of Street Sweeping
Action
Project
Mile (miles)
Yes
Miles of city, county and state roads that are swept to reduce stormwater pollution during each EIP reporting year as part of regular operations and maintenance procedures. Capital stormwater infrastructure improvement activities are captured by other PMs. Sweeping streets reduces a major source of pollutants in stormwater runoff that flows to Lake Tahoe and works toward reducing clarity loss.

Miles of Street Sweeping is reported as a Performance Measure in the EIP Project Tracker. Indicators used for EIP reporting are summarized in an annual report and highlighted each year during the Lake Tahoe Summit.

Reporting Guidance

Fine sediment particles – Sediment particles with diameter of less than 16 micrometers. 

Urban jurisdictions – These include counties, state highway departments and cities within the Tahoe Basin.

Types of Street Sweepers

  1. Mechanical Broom – Mechanical Broom Sweepers use brooms typically spanning the width of the sweeper that contact the pavement surface and sweep debris onto a conveyer which deposits the debris into a hopper. Mechanical broom sweepers commonly spray water on the pavement surface to reduce the generation of fugitive dust, which can reduce the efficiency of material recovery. 
  2. Mechanical + Vacuum Sweeper (Tandem) – Vacuum Sweepers use gutter brooms to remove particles from the street. However, the refuse is then placed in the path of a vacuum intake that transports the dirt to the hopper. The transported dirt is usually saturated with water. Tandem sweeping operations involve two successive cleaning passes, first by a mechanical (broom and conveyor belt) sweeper, followed immediately by a vacuum-assisted sweeper.
  3. Regenerative Air – Regenerative Air Sweepers use a recirculating air supply to blast the pavement surface with air to dislodge and entrain sediment and debris in the air. A vacuum system is positioned to pull the blasted air, and the material it has entrained, back into the sweeper hopper. 
  4. High-Efficiency Vacuum-Assisted Dry Sweeper – High Efficiency Street Sweepers are designed with an advanced air filtration system for dust containment in combination with the use of both main and gutter brooms. 

The miles of streets swept are reported annually by each jurisdiction, based on information from their internal operations tracking. Urban jurisdictions develop Annual Stormwater Reports and submit all materials by December 31st of each year for the reporting year ending September 30 (Lahontan & NDEP, 2011). 

Tahoe Basin roads are swept using one of the types of street sweepers outline under Critical Definitions, which vary in their effectiveness and operational costs. The Equipment Type Subcategory provides additional understanding about street sweeping procedures, and should align with inputs into the PRLM used by the TMDL.
