 Lahm originally dictated that the location be within 10 miles of San Antonio, but difficulties finding a site suited to the planned design, and the large size required, forced a resumption of the search in October 1927 out to an expanded distance of 30 miles.While the location problem was being settled, Lahm assigned Clark to begin work on plans and layout of the new base on December 8, 1927.A location near Schertz, 18 miles from San Antonio, was obtained by the San Antonio Chamber of Commerce and offered to Lahm on the last day of 1927, who sent the proposal to Secretary of War Dwight F. Davis.
