2017 Street Sweeping Program Improvements

By 2022, the City of San Mateo will be required to prevent all trash from entering the bay through our storm drains to meet mandates set by the San Francisco Bay Regional Water Quality Control Board.

Latest News 

(Updated 2/9/18)Phase 1 and 2 signage

  • The new street sweeping routes are now being swept as of December 2017.  For most of the streets in the City, citations resumed on January 10.  Some areas only had signs installed recently (known as "Phase II"). For these streets, warning notices are being posted on cars parked in violation of the signage starting February 8, with $41 citations  on March 12.

Sweeping Based On Trash Generation

Based on these the amount of trash generated on a given street, route schedules and freTrashGenerationStreetsquency have been modified for 2018 so that high generation areas and new development will receive adequate service and lower generation areas are not swept as frequently.  These improvements to the sweeping program will help us meet the trash reduction requirements and keep our bay clean.   Please see below for more detail on the designations, what adjustments are taking place, and maps to see how your home or business is affected.

  • Green/Low generation streets:  
    During leaf-season (October to March), these streets will be swept bi-weekly.
    From April to September, these streets will be swept monthly.
  • Yellow/Moderate generation streets:
    Year-round bi-weekly sweeping
  • Red/High generation streets:
    Year-round bi-weekly sweeping, and addition of parking restriction signs (see below)

Parking Restriction Signage

Parking restriction signs have been expanded in red/high generation areas to keep streets clear for their scheduled sweeping. Without cars blocking the gutter of these high-priority streets, the sweepers can thoroughly clean the street and prevent litter from entering the bay.  These signs will only restrict parking on the days and times where the gutters need to be clear for sweeping. See the map at right for the proposed new signage.

Any vehicles that park in violation of the posted two-hour window will be subject to citation by the Police Department, once enforcement has begun. Most of the signs are being enforced as of January, with the remaining enforcement to begin March 12, 2018.  Please see the Phase I/II map above to see the enforcement status for the streets near you. 

The new routes are being swept now. You can check your current sweeping day on the updated MyStreet online service, as well as sign up for email notifications that can remind you to move your car prior to sweeping time.

Trash Generation Assessment Process

To meet these mandates, the City assessed the amount of trash generated on every street throughout San Mateo and put them in three categories. Trash generation ratings of Low, Moderate, and High were determined through a multi-step process:

  1. A draft Trash Generation map was prepared based on land use, population density, and demographic data as part of the Trash Generation Project to address trash reduction and compliance with the National Pollutant Discharge Elimination System (NPDES) permit. For more details on the Trash Generation Project, see the Technical Memo (2012).
  2. Based on this established methodology, City of San Mateo staff gathered trash collection data from the street sweeping program, and conducted site visit observations over a period of time to verify 90% of the City’s moderate and high generation trash areas.

 For in-depth information on the City’s trash load reduction strategy, see the Long-Term Trash Load Reduction Plan and Assessment Strategy (8 Mb).
