Environmental Remediation Obligations [Abstract]
Environmental Matters	Environmental Matters We are subject to numerous environmental laws and regulations. The operation of dry cleaning and gas station facilities at our shopping centers are the principal environmental concerns. We require that the tenants who operate these facilities do so in material compliance with current laws and regulations and we have established procedures to monitor dry cleaning operations. Where available, we have applied and been accepted into state sponsored environmental programs. Several properties in the portfolio will require or are currently undergoing varying levels of environmental remediation; however, we have environmental insurance policies covering most of our properties which limits our exposure to some of these conditions. Management believes that the ultimate disposition of currently known environmental matters will not have a material effect on our financial position, liquidity or operations.

The entire disclosure for environmental loss contingencies, such as presence of hazardous waste, relevant information from reports issued by regulators, and estimated costs to achieve compliance with regulatory requirements. This element may be used for all of an entity's disclosures about environmental loss contingencies.
