Illegal Dumping

Illegal dumping is a growing challenge for the sidewalks of San Francisco, with debris such as furniture, mattresses and appliances left out on the sidewalks near homes, schools and places of business. There is a significant cost associated with the seemingly innocent practice of unloading unwanted items and expecting that there is a service in place to pick them up.

Sidewalk dumping:

Flood Preparedness & Storm Readiness

San Francisco winter storms can cause floods, landslides, uprooted trees, and downed or broken utility lines in almost any neighborhood. The City and County of San Francisco has prepared safety tips to help you have a safe winter and protect yourself and your property. For all emergencies, call 911. To report downed tree limbs, clogged catch basins or localized flooding, call 311.

How to prepare for the next storm

Overflowing Catchbasins

Catch basins are the storm drains located at most corners of the City's street intersections. They are designed to allow rainwater to drain from the gutters and into the sewer system. During rainstorms, trash and debris can prevent rainwater from entering a catchbasin. Trash and debris can also collect at the bottom of the catchbasin, allowing water to build up and spill out of the catch basins ultimately causing street flooding.  Leaves can be particularly problematic.


Public Works will provide San Francisco residents and business up to 10 free sandbags leading up to and during severe rainstorms. They are intended for properties prone to flooding. Sandbags can be retrieved Monday-Saturday, 8 a.m. to 2 p.m., at the Public Works’ operations yard, Marin Street/Kansas Street gate. Bring proof of address.

Approved Street Tree List

The Urban Forestry Council annually reviews and updates this list of trees, in collaboration with public and non-profit urban forestry stakeholders, including San Francisco’s Department of Public Works Urban Forestry Division and Friends of the Urban Forest.

Pine Pitch Canker Recommendations

In an effort to identify potential public safety risks posed by diseased Pine trees, Public Works and the City’s Urban Forestry Council are asking property owners to inspect the condition of pine trees within their property or on their sidewalks that appear dead or whose branch tips in the upper crown of the tree begin to die, the first sign of a regional fungal disease.

Gigantic 3 Recycling Program

The Gigantic 3 program is a free bulky item drop off service allows residents to get rid of unwanted household items at various locations around the City, and usually coincides with Public Works' Community Clean Team events.

Appointments are recommended, please call Recology Sunset Scavenger at (415) 330-1300 before 1:00 pm Friday, March 17th. You must be a resident of the host district to make an appointment.

Significant and Landmark Trees

In 2007, The Urban Forestry Ordinance of the Public Works Code was revised by the Board of Supervisors to protect certain trees on private property that are close to the public right-of-way.

Significant trees are within 10 feet of the public right-of-way and also meet one of the following size requirements:

  • 20 feet or greater in height,
  • 15 feet or greater canopy width, or
  • 12 inches or greater diameter of trunk measured at 4.5 feet above grade.
