Orange County Coastal Regional Sediment Management Plan The Plan The resulting Plan, which is specific to Orange County beaches and shorelines, includes an array of potential projects with implementation priorities that are useful to stakeholders. This Plan is technically, economically, and environmentally feasible, includes recommendations for financial viability, includes suggestions for possible governance approaches, and includes recommendations on steps for Plan implementation. The Plan activities, listed in Table ES.1, were prioritized based on a combination of stakeholder interests, perceived needs, recreational benefits, shore protection benefits, funding availability, costs, habitat impacts, regulatory requirements, and permitability. Plan activities were separated into type as follows: plan performance activities designed to improve performance of the Plan; construction projects that can be built and support coastal RSM; and governance and regulation activities to provide the governance structure and improve government regulation to facilitate Plan implementation. Almost all of the Plan activities can begin immediately, some are ongoing, some would have completion dates, some would be continuous, and some would be recurring without end. Plan activities are listed in Table ES.1 and discussed in detail in Chapter 4 of this report.

The Plan outlined in the current report addresses coastal maintenance needs through a multi-pronged approach ranging across geographic regions and utilizing many possible methods. Some of the Plan activities can be carried out through existing institutions and do not require development of a joint powers authority (JPA). Other Plan activities, such as development of a SCOUP for Newport Harbor may be carried out by local agencies. Beyond these small or ongoing projects, an organized effort would likely be required to fully implement the Plan. The first steps to fully implement 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 should be carried out. From there, collaborative discussions between local agencies would be required before a JPA could be modified or formed. This JPA would have the task of implementing and updating the Plan over the next 50 years. Many of the Plan activities can be carried out separately through various agencies and agendas, however dedicated staff or an agency would have a greater ability to implement the Plan through the many obstacles. The Plan describes and recommends an assortment of activities that should be carried out to fully embrace and implement coastal RSM in Orange County. Everest International Consultants, Inc. ix
