Name: Limit of Moderate Wave Action

Display Field: DFIRM_ID

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: The LiMWA line identifies the "Coastal A Zone," an area where wave action is sufficient to cause significant damage to structures not built to coastal standards. While not a formal regulatory boundary for the NFIP, many local building codes require V-Zone (coastal high hazard) construction standards seaward of this line.
