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

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. In November 2011, the City of Los Angeles adopted the Stormwater LID Ordinance (Original Ordinance #181899, updated September 2015-Ordinance #183833, and updated April 2024-Ordinance #188125) to support this effort.

New development and redevelopment projects are required to incorporate LID measures into their design plans as part of their plan check review and building permit approval process. Please use the LID Portal to start your LID Counter request for plan check and other building permit related items

To begin the process, please select an option from the Applications drop down menu atop this page. Once the application has been submitted, it will be reviewed in the order it was received.
