Descriptive nameFloodplains - Areas of revision not yet in the GIS floodplain layers.
File namefp_lomxp
Spatial domainPima County
Abstractfp_lomxp displays area boundaries in which the floodplain data has been revised by Letter Of Map Revision (LOMR), BUT THE UPDATED BOUNDARIES HAVE NOT YET BEEN INPUT INTO THE GIS FLOODPLAIN LAYERS, I.E. FP_DFIRM, FP_FLWAY, ETC.
Known errors/qualificationsThe revision area boundaries were screen digitized using the FIRM panel as a reference. This layer may or may not have data in it at any given time. As LOMR documents are processed the relevant information is removed from this layer. A place holder polygon exits in the SW corner of the data in order to prevent the data set from registering as NULL when it is empty. This is necessary since an empty shapefile can't be converted to coverage format as required by the library. The place holder polygon is attributed as PLACEHOLDER in the CASENUM field.

The MapGuide layer name for this layer varies:
- Public maps: Floodplain not digitized - See paper documentation
- Internal maps: LOMR Revisions - See LOMR document

12/2013: While this layer is maintained as a Shapefile, the coverage format is still required for certain nightly processing. See Steve Whitney. - FEMA floodplain data extraction process
