determined by Indian River County) north of R-40. Supplemental volumes will be determined through agreement between the County and the District (target volumes are anticipated to be in the range of 15,000 cubic yards). A figure identifying the location of the Supplemental Fill template (R-17 — R-40) is attached as Exhibit 2 and incorporated by reference herein.District and Indian River County Responsibilities: In order to maximize success of the Supplemental Nourishment and Sand Bypassing Plans, the District and Indian River County must cooperate closely, and any such placement should be guided by the Sebastian Inlet Management Plan, and Indian River County's Beach Preservation Plan and Dune Maintenance Program. • The District will be responsible for fill excavation, transportation and placement of beach compatible sand on downdrift beaches to meet its bypassing objective. • Indian River County should be responsible for: 1) identifying, designing, permitting, and constructing supplemental fill access locations south of R- 17; and 2) identifying, designing and permitting supplemental fill placement locations south of R-17; and 3) securing necessary releases and approvals from upland property owners. • The District should be responsible for coordinating (with the Department and Indian River County) use of supplemental fill access and placement locations north of R-17. • The District should be responsible for maintaining (during construction) and restoring any fill access locations (to their immediate pre -use condition) it uses to place supplemental sand. • Indian River County should reimburse the District for any incremental increase in transportation costs for sand placement south of R-17.The County and the District should coordinate monitoring to maximize efficiency and minimize overall cost. 5. Monitoring. The District agrees to assume all physical and biological monitoring associated with the approved Sectors 1 and 2 fill template as required by permit for purposes of measuring the potential impacts to nearshore hard bottom. The County agrees to share all historical monitoring data collected by the County for purposes of establishing baselines. In the event of a County sponsored beach renourishment project north of R-17, then the County, District and agencies will renegotiate the responsibilities of permit required monitoring. 6. Storm Loss Mitigation. The County will undertake applications for storm Toss mitigation for Sectors 1 and 2 required by state or federal agencies for impacts resulting from named storms and identified by disaster declarations. The County's "engineered beach" template qualifies the project for such reimbursement programs. For renourishment events to offset storm loss, the County and District will coordinate and give priority to any sand available in the District's sand trap and/or DMMA for potential beach or dune placement. If the County and its coastal engineer select an offshore or upland sand source
