"Four U.S. states - Virginia, California, Alaska, and Florida - have active launch sites. Given the complexity of developing a rocket launch site, SpaceX will be pursuing several options concurrently in order to fully understand the pros and cons of each location."
Availability of the Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for Issuing an Experimental Permit to SpaceX for Operation of the Grasshopper Vehicle at the McGregor Test Site, Texas
"Although an experimental permit would authorize an unlimited number of launches, the FAA, in conjunction with SpaceX, developed a conservative set of assumptions regarding the possible number of launches that could be conducted under any one experimental permit for the Grasshopper RLV at the McGregor test site. The FAA has assumed that SpaceX would conduct up to 70 annual suborbital launches of the Grasshopper RLV under an experimental permit at the McGregor test site. This estimation is a conservative number and considers potential multiple launches per day and potential launch failures."
