About this Dataset

I17 LeveeCenterlineClass 2012

This line feature class represents levee centerlines for 93 Levee Maintenance Agencies/Reclamation Districts in the Sacramento-San Joaquin Delta. The centerline features contain levee geometry classification that indicates whether a levee segment meets the FEMA’s Hazard Mitigation Plan (HMP) or USACE’s Public Law 84-99 (PL8499) Delta levee standards. There are four categories used in the classification of the centerlines: HMP, Below HMP, Minimally Below HMP, and PL84-99. The classification and other data associated with these centerlines were produced as results of the Levee Geometry Assessment analysis performed by the California Department of Water Resources Delta Levees and Environmental Engineering Branch in 2012. The centerlines used in this analysis are part of the dataset produced from the Delta Levee Anatomy Mapping Project in 2011 through a contract between DWR and the Geographic Information Center at California State University, Chico.
