| Resource Type |
| Unverified: Resource areas hypothesized to exist on the basis of indirect evidence for the presence of beach-quality sand |
| Unverified Plus: Resource areas hypothesized to exist on the basis of geophysical evidence (seismic profiles, bathymetry, or side scan sonar) and at least one geotechnical core or surficial samples verifying beach-quality sand |
| Potential: Resource areas with beach-quality sand whose existence has been verified through preliminary geotechnical and geophysical data (with vibracores approximately one mile apart). Thickness and/or lateral extent has been preliminarily determined |
| Proven: Resource areas with beach-quality sand whose thickness and lateral extent have been fully determined through design-level geotechnical data and in most cases are permitted |
| Unusable: All beach-compatible material has been removed from the area prior to SAND Study or 2:sand source is inaccessible due to current conditions or 3:Area was investigated and presence of non-beach quality material throughout area was verified |
