Check your property’s environmental information

Check in the Property Information Map (PIM). 

Search with your address or block and lot numbers.

Look in the Environmental Information section.

Check for:

• Slope of greater than 20% or 25%
• Geotechnical risk like landslides and liquefaction
• Soil and groundwater contamination (Cortese and Maher ordinances)
• Other physical conditions like excess air pollution, archeological areas, and flood zones

Email pic@sfgov.org for additional information on any physical conditions listed for your property.

If your project will disturb any soil on a Hunters Point Shipyard Parcel, apply to the Article 31 Program.

If your project will excavate 50 cubic yards or more, apply to the Maher program.

Check if your project includes:

• Construction of a new building or structure with more than 1,000 square feet of new projected roof area
• Horizontal or vertical additions with more than 500 square feet of new projected roof area
• Shoring
• Underpinning
• Grading, including excavation or fill, of over 50 cubic yards of earth materials

We may also review your project and decide it could have a substantial impact on the slope stability.

Comply with slope protection requirements for your building project.

You will need a report from a geotechnical engineer if your project includes: 

• A new building (except one-story storage or utility like a shed or garage)
• Horizontal additions that increase the footprint more than 50% of the existing square footage
• Slope fills, gradings, special foundations, or other drainage or soil work in the Properties Subject to the Slope and Seismic Hazard Zone Protection Act (SSPA) Ordinance Information Sheet S-05.
