The Districts’ review process is linear – all projects start at the simplest level of review (Tier 1) and move to more thorough review if more information is needed on potential impacts or mitigation is required. You will be notified by District staff if your project requires an additional tier of review.
The next level of review (Tier 2) is completed for projects that may affect levees or interior drainage systems within the Districts.
The highest level of review (Tier 3) is done on applications that require a lot of time or expense for the Districts, such as those with community interest and those requiring legal counsel or outside contractor expertise. This also includes projects that trigger U.S. Army Corps of Engineers (USACE) requirements for alteration of federal levees.
In all cases, the Districts provide comments and conditions for approval to the agency processing your permit application. Final development permits are issued by the agency processing your application.
