ITEM 13: REQUEST: Consider (a) .a land exchange of 2.77 acres of Trustees -owned property located in St. Sebastian River Preserve State Park (SSRPSP) for 2.79 acres of existing county -owned road right-of- way within SSRPSP and declare the 2.77 acres of Trustee property as no longer needed for conservation purposes if replaced by the 2.79 acres of county property to be donated to the state, and (b) the associated land exchange of 6.84 acres of Trustees -owned property in SSRPSP for a 7.55 acre island of county -owned property for a future stormwater retention pond necessary for the road widening of County Road 512 and declare the 6.84 acres of Trustees' property as no longer needed for conservation purposes if replaced by the 7.55 acres of county property to be donated to the state. LOCATION: Indian River County DSL Staff Remarks: The Division of State Lands (DSL) received a request from the Indian River Board of County Commissioners (County) to exchange approximately 2.77 acres of state-owned land for 2.79 acres of land currently located within county -owned right-of-way. The County is in the process of widening County Road 512 from a two-lane to a four -lane road as necessary to meet the County's projected growth in traffic volume for the corridor. At the same time, the County would like to realign 102nd Terrace that currently crosses through SSRPSP. The parcel the County will convey is part of an existing two-lane road right-of-way road (102nd Terrace) approximately 80 feet wide that runs directly through a portion of SSRPSP (2.79 acres). Current patterns have heavy traffic entering onto County Road 512 from south 101st Avenue. Traffic subsequently heads west along County Road 512 then turns north on 102"d Terrace, which is the road that travels through the SSRPSP. Acquiring this portion of 102nd Terrace will not only assist with the safety issues associated with the widening of County Road 512, there will be an overall net increase in acreage to the SSRPSP. Further, the unified traffic signalization at 101st Avenue will eliminate the need to locate more than one traffic signal within this short stretch. The 2.77 acre parcel the Board of Trustees will convey borders the extreme outer boundary of the SSRPSP and will be approximately 70 feet wide. A proposed two-lane roadway (101st Avenue) would replace the existing two-lane road that currently runs through the SSRPSP. The proposed road will be constructed in a similar alignment as the current two-lane road and will also merge into 102nd Avenue. The new road will help to alleviate some of the safety issues associated with the road widening project of County Road 512. The County has agreed to restore the vacated portions of the new road right-of-way to natural conditions (i.e., remove fill, replant native species). Further, the County will move fill off the existing road to the new road. The County has agreed to remove invasive species within SSRPSP. Specifically, the County is willing to expand the area of exotics removal beyond the immediate footprint of the abandoned alignment to an area in the vicinity of the abandoned alignment and the new alignment. Additionally, the County will remove invasive species in the overall SSRPSP area west of the new alignment extending to and including the proposed stormwater tract area. Concurrent with the request above, and in association with the widening of County Road 512, the County seeks ARC approval to exchange 6.84 acres of SSRPSP land it needs for a stormwater retention pond, for a 7.55 acre island in the St. Sebastian River. It will be necessary for the stormwater retention pond to be located on the land currently within the SSRPSP's southwestern most boundary. The outfall for the pond ("Pond A") will discharge to a new ditch that will parallel CR 512 (within the CR 512 RAN) and will go to "Pond B" at the North County Park. Pond B will have an outfall that discharges into a ditch. That ditch goes across the Sebastian River Middle School property and into a slough on property east of the school, and then discharges to the south prong of the Sebastian River. In exchange, the County has proposed to convey a 7.55 acre private island in the St. Sebastian River and adjacent to the SSRPSP. The island will be added to the management of the SSRPSP and is within the optimum-managementbaundades-for-the-SSFP-SP.�he-island-is-a-mixture-of-estuarine-wetlands mangrove
