Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS During 2014, we had a gain of $1,145,000 related to a land sale of $1,268,000 sold to the TA/Petro joint venture. Related to the sale, we recognized $458,000 of the gain and deferred $687,000 of the gain, which will be recognized at the time we exit the joint venture or the joint venture is terminated. TA/Petro is an unconsolidated joint venture with TravelCenters of America, LLC for the development and management of travel plazas and convenience stores. The company has 50% voting rights and shares 60% of profit and losses in this joint venture, which owns and operates travel plazas/commercial highway operations in TRCC. See Note 17 (Investments in Unconsolidated and Consolidated Joint Ventures) of the Notes to Consolidated Financial Statements for further detail regarding the TA/Petro unconsolidated joint venture. Also during 2014, the Company completed the asset purchase of DMB TMV LLC's membership interest in TMV LLC, which increased our development in process balance by $101,648,000. TCWD is a not-for-profit governmental entity, organized on December 28, 1965, pursuant to Division 13 of the Water Code, State of California. TCWD is a landowner voting district, which requires an elector, or voter, to be an owner of land located within the district. TCWD was organized to provide the water needs for future municipal and industrial development. The Company is the largest landowner and taxpayer within TCWD. The Company has a water service contract with TCWD that entitles us to receive all of TCWD’s State Water Project entitlement and all of TCWD’s banked water. TCWD is also entitled to make assessments of all taxpayers within the district, to the extent funds are required to cover expenses and to charge water users within the district for the use of water. From time to time, we transact with TCWD in the ordinary course of business. We believe that the terms negotiated for all transactions are no less favorable than those that could be negotiated in arm’s length transactions.
