Our venture partner contributed a land site that is entitled for 1.3 million square feet of development it controls at Potomac Yard Landbay F, while we contributed the adjacent land with over 700,000 square feet of estimated development capacity at Potomac Yard Landbay G. We will also act as pre-developer, developer, property manager and leasing agent for all future commercial and residential properties on the site.
