The City is now accepting RGP 54 Year 3 - 2018 pre-application screening requests.  

Please click HERE for the current status of your submitted RGP 54 application (updated May 2, 2018).


All dredging projects, even the simplest in nature, require permits issued by multiple federal and state agencies before dredging can proceed. To make the process easier for applicants, the City (Harbor Resources) manages the permitting responsibility for the new Regional General Permit program (RGP 54) to allow small maintenance dredging projects within designated areas of Newport Harbor.  Because the permit conditions from the federal and state agencies are complex, we have outlined key steps, and have also provided helpful information for you on this page.  Our goal is to simplify the process so we can ensure a successful and efficient program.  If you have any questions, please contact Harbor Resources at 949-644-3044 or  

RGP 54 Application Steps




Step 1. Pre-application screening – Submit the following to Harbor Resources to initiate the process:

1. Proposed dredging footprint;  

2. Proposed disposal footprint (if proposing beach replenishment), or a note that you are proposing disposal at either the offshore LA-3 ocean disposal site or an inland disposal site; and

3. Approximate dredging volume (in cubic yards).

The footprints should be either a hand-marked drawing using an aerial image or an electronic “shapefile” (Horizontal Datum – California State Plan, Zone 6, NAD83; Vertical Datum – Mean Lower Low Water). Pre-application screening submittal may either be emailed to Harbor Resources or hand-delivered to 100 Civic Center Drive, Newport Beach, CA 92660.
