Segment Reporting [Abstract]
Number of reportable segments	2
Quantitative threshold of revenues, profit or loss and assets for identifying reportable segments	The Company’s chief operating decision maker may review operational and financial data on a property basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital. The Company evaluates individual property performance primarily based on net operating income before depreciation, amortization and certain nonrecurring items. Each consolidated shopping center is considered a separate operating segment; however, each shopping center on a stand-alone basis represents less than 10% of the revenues, profit or loss, and assets of the combined reported operating segment and meets the majority of the aggregation criteria under the applicable standard.
