• Familiarize Study Contractor with study area• Characterize shoreline exposure and morphology• Inventory and field-verify coastal structures• Field-verify geospatial datasets• Collect data pertinent to coastal analyses, per G&S• Demonstrate local knowledge and site familiarity

to communities, document conditions

FEMA Guidelines and Specifications provide verylimited direction on field recon objectives.Objectives can be tailored to meet Contractor needs

Need sediment grain size to determine time scale of erosion response

Estimate D50FineMediumCoarse(visually or lab analysis)

(bin into grainsize categories)
