Sonoma Coast Marathon CDP Requirements
Hello All,
We have been asked for our opinion regarding the coastal development permitting (CDP) requirements associated with the proposed Sonoma Coast Marathon. As we have previously informed Sonoma County PRMD and Board of Supervisor staff, and based on the information we have been provided and our current understandings, it is clear to us that the proposed race activities constitute development under the Coastal Act and the LCP, and therefore the Marathon requires a CDP from Sonoma County. If approved by the County, such CDP approval action would be appealable to the Coastal Commission due to its location, but a County denial action on a CDP would not be appealable.

With respect to the potential for the race to qualify as a CDP-exempt temporary event pursuant to the Coastal Commission’s guidelines, the Executive Director has determined that the race has the potential for significant adverse impacts on coastal resources, including public access, that it does not qualify for a temporary event CDP exclusion, and that a CDP is required.
I hope the foregoing helps to clarify the CDP requirements associated with the proposed Sonoma Cost Marathon. Feel free to contact me should you have any questions.
Thank you,
Jeannine Manna
