Before you do anything you need to:1) talk to the city zoning department and see what uses are allowed on the property.2) check out the survey to see if there are any portions that are not usable due to setbacks, easements, etc. in addition to what the maximum buildable area is based on the zoning restrictions.3) see what utilities you have available at the tract (water, sewer, gas, electric).4) based on the above, see what the options are and if you think any of those would be profitable.5) decide if you want to build and operate whatever that business is or just sell the land to someone else to build.
