The application must be made on forms provided by CVFPB (3615 and 3615a) and must contain the following information:

  1. A concise and accurate description of the proposed project, being sure to include all items that are to be authorized under the issued permit.

The LMA may be a reclamation district, a levee district, a State maintenance area, a county, or some other agency that is responsible for levee or channel maintenance. Special conditions may be added to the permit at the request of the agency. If the maintaining agency delays or declines to endorse the application, it may be submitted to the CVFPB without endorsement with a written explanation as to why the application was not endorsed by the maintaining agency.

The environmental questionnaire (form 3615a) must be completed and submitted as part of your application.
  8. Note when the proposed project is tentatively scheduled for construction and if there are any funding constraints. Keep in mind that the review and permitting process can take six months or more to complete.
