Descriptive nameFloodplains - Areas of revision not yet in the GIS floodplain layers - 1999
File namefk_lomxp
Spatial domainPima County
Abstractfk_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.

This layer is based on the 1999 release of the Digital FIRM data by FEMA. Updates to this data have been applied up to June 16th, 2011.

This K Series layer is not on any MapGuide maps because it is empty and will not be updated as the layer has been superceded by fp_lomxp.
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.
