Should you want to dive into the actual agreements signed by the Spokane Public Facilities District with the Walt Worthy company that intends to build a large downtown convention center hotel, here is the link.
Look down near the bottom of that page. The major links are to the Joint Development Agreement and the Purchase and Sale Agreement. In the long and generally boring sale agreement is the very basic and simple to understand condition: the land is being sold as-is to the developer.
Wednesday's Spokesman Review story on the actions taken so far to build the huge hotel (with 900 parking spaces) is at this link.
The same site provided this jpg image of the tentative floor plan of the main floor of the proposed 15-level building. The parking area/garage is in the lower right, the southeast corner of the building, in this plan.
