Indian River County Pelican Island National Wildlife Refuge Restoration Project Coastal Tech Project No. 02460. OP Scope of Work General Information : Indian River County (COUNTY), in collaboration with the Pelican Island National Wildlife Refuge (Refuge) staff, is seeking to restore a maritime marsh area altered by construction of mosquito control ditches and proximity to agricultural land use. The project site (Site) is located on a 6 . 1 acre parcel known as the "Triangular Area" and depicted on the drawing prepared for the COUNTY by Carter Associates (CAI; survey dated August 10, 2004) . This survey provides a detailed description of the Site and contains important baseline elevation data which will be used throughout the duration of the project proposed herein. This proposal describes engineering, permitting, and design services performed by COASTAL TECH in pursuit of marsh restoration as described below : Task 1 - Site Assessment Task la — Existing Conditions : COASTAL TECH will use recent data ( aerial photography, surveys, maps, water quality data, etc . ) as available from the COUNTY and Refuge staff as baseline data. COASTAL TECH will visit the Site to observe, identify, and measure existing ecological and physical resources (upland, wetland) using available GPS -GIS technology and including : ( 1 ) soils, (2) topography (not reflected on CAI survey) and apparent drainage/tidal pathways , (3 ) surface water salinity, and (4) vegetative associations . COASTAL TECH will evaluate these data and then map existing conditions using ( 1 ) a Level IV FLUCFCS map , (2) ArcGIS 9 . 0 data layers and (3 ) associated land cover maps depicting specific themes that may include, but are not limited to : ( 1 ) soils, (2) site topography and surface water drainage, and (3 ) potential habitat that may be utilized by State and/or federally listed wildlife species . COASTAL TECH will research existing databases to identify listed species which are recorded as occurring within the vicinity of the Site . COASTAL TECH will then generate a summary of listed wildlife species that may occur on the Site . All geospatial data and related maps will be Florida Geographical Data Library compliant . This information will be used during the formulation of the project ' s conceptual restoration design and to facilitate project permitting. COASTAL TECH will identify any additional data or surveys necessary for completion of the conceptual design; the COUNTY shall provide such additional data or surveys . COASTAL TECH will also prepare a written summary of land use, wherein descriptions of the dominant vegetative cover and the overall intactness (degree of disturbance) of each vegetative community, as identified on the FLUCFCS map , will be provided. Task lb — Historical Conditions : Utilizing the oldest available aerial photography ( 1943 ?) , as made available by the COUNTY and Refuge staff, COASTAL TECH will interpret historical SITE conditions (i . e . , vegetative associations) relevant to the goals and objectives of this project . COASTAL TECH will then prepare an ArcGIS 9 . 0 data layer and associated maps summarizing the historical conditions that may include , but are not limited to : ( 1 ) local relief or topography, (2) surface water drainage, and (3 ) the distribution and intactness of 1 of 4 January 18, 2005 EXHIBIT A
