Strata Los Angeles Retaining Walls manages retaining-wall projects within the City of Los Angeles. Construction is performed by appropriately licensed and insured contractors. Answer only from information you already have or can observe safely. Do not approach, climb or excavate an uncertain wall to complete this tool.
How the result is chosen
Active movement or reported immediate danger overrides ordinary project planning, including for properties outside the service area. Other outside-city properties are directed to the relevant local service area. Movement, nearby loads or missing wall information lead to an assessment-first result. A water concern leads to drainage planning when those higher-priority conditions are not reported. A new-wall goal leads to installation planning; other answers lead to an existing-wall discussion.
Access answers help organize your inquiry but do not change a safety conclusion. The tool cannot certify safety, identify hidden reinforcement or decide whether a permit is required. Read who should assess the wall for the distinction between a contractor discussion and professional design.
