Review Process

Permits

To keep things simple and provide applicants with as much information as possible, we use a tiered approach. The level of review - Tier 1, Tier 2 or Tier 3 - is based on a project’s size, location, complexity, and potential impact to our levees. All projects start at the simplest level and move to a more thorough review if more information is needed or mitigation is required.

Permits are free. CDID #1 does not charge any application or review fees. Contact us to set up a pre-application meeting to identify issues and explain submittal requirements.

  1. Tier 1
  2. Tier 2
  3. Tier 3

Tier 1: Simple Review (Non-Federal Permits)

Tier 1 reviews are the most common. This is appropriate for residential applicants wanting to make a relatively minor improvement within our interior drainage system. 

Examples include:

  • Fences
  • French drains
  • Gardens
  • Landscaping
  • Outbuildings
