Orange County Coastal Regional Sediment Management Plan 4.26 Update Sediment Transport Studies for Southern Orange County The sediment budget information for southern Orange County in the northern portion of the Oceanside Littoral Cell is from a Coast of California Storm and Tidal Wave Study (CCSTWS) published by the USACE in 1991. Physical data referenced in this CCSTWS is valid through the 1970’s and 1980’s which is three to four decades old at this point. This activity would be to perform sediment transport studies for southern Orange County to be more recent and relevant. Everest International Consultants, Inc. 4.17
Orange County Coastal Regional Sediment Management Plan 5. CONCLUSIONS While some beaches in Orange County are wide and healthy, such as those within the Huntington Beach Littoral Cell, there are many that have chronic erosion problems, such as East Beach, Seal Beach and beaches southeast of Dana Point (e.g., Capistrano County Beach and San Clemente City Beach). Even the wide and healthy beaches from Sunset Beach to West Newport Beach are dependent on ongoing nourishment activities that may come under threat if not maintained. The Plan outlined in the current report addresses beach maintenance and other coastal needs through a multi-pronged approach ranging from small individual construction projects all the way up to changing state and federal regulations. Also, the activities within the Plan range geographically from the upland streams and rivers of Los Angeles and Riverside County, down to the beaches, and into the nearshore areas of Orange County. Some of the recommended Plan activities can be carried out through existing institutions and do not necessarily require development of a dedicated JPA. Examples are the ongoing Surfside- Sunset Beach nourishment project and the proposed San Clemente Shoreline Project which are USACE projects. Other Plan recommendations such as development of a SCOUP for Newport Harbor may be carried out by local agencies such as the City of Newport Beach Harbor Resources Division. Beyond these small or ongoing projects, an organized effort would be required to fully implement the Plan. The first steps associated with fully implementing the Plan are public outreach and education. This would be directed towards professionals and decision makers informing them what the Plan is and how it is to be carried out. From there, local jurisdictions should begin collaborative discussions to consider whether a JPA could be modified or formed. This JPA would have the task of implementing and updating the Plan over the next 50 years. The JPA would have the challenging tasks of introducing and explaining the Plan to the public and to decision makers, raising funds to implement the Plan during tough economic times, and then steering the Plan through the regulatory process. Given these difficulties, it is hard to imagine a group or agency taking on these efforts on a part time basis, thus the JPA would likely require full time staff and a dedicated board of directors. While no one is certain of the future, it may be possible that many of the recommended Plan activities will be carried out through various piecemeal agencies and agendas. On the other hand, a dedicated agency would have a greater ability to press these Plan activities through the various obstacles. Likewise, it may be possible that the lower of the sea level rise scenarios will occur and upland sand bypassing will become the norm, so beaches could be maintained or widened without much organized effort. This scenario would be driven by good luck more than good governance. Good governance however requires diligent thoughtful planning. The Plan provided herein describes and recommends a range of activities that should be carried out to implement coastal RSM in Orange County. Everest International Consultants, Inc. 5.1
