Welcome to the Low Impact Development (LID) Plan Check Submittal portal

Low Impact Development (LID) is a leading stormwater management strategy that seeks to mitigate the impacts of runoff and stormwater pollution as close to its source as possible. Los Angeles' LID ordinance became effective in May 2012.

The requirement to incorporate LID measures into the design plans of new development and redevelopment projects in order to mitigate stormwater quality impacts is implemented through the City’s plan review and approval process.

Utilize this portal to submit the required submittal documents for review by the LID counter plan checkers.

Select "Applications" in the blue banner above to begin the process.

Once an application has been submitted the status of review can be checked online 24 hours a day, 7 days a week.
