• 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

Where is additional information needed?
15FMA September 7, 2011
Need sediment grain size to determine time scale of erosion response
Estimate D50FineMediumCoarse(visually or lab analysis)
(bin into grainsize categories)
Coastal Erosion MethodsAnd Data Requirements
16FMA September 7, 2011
Need rock armor characteristics for wave runup and overtopping
• Armor size• Porosity• Roughness• Condition
