The single-top production cross section is one third that of the top-pair production cross section at the LHC. During a year of data-taking, assuming an average luminosity of 1033 cm-2 s-1 and a CMS energy of 14 TeV, the determination of the major contributions to the total single-top cross section should be achievable. Comparisons between the measured cross sections and the theoretical predictions will provide a crucial test of the standard model. These measurements should also lead to the first direct measurement of |Vtb|, with a precision at the level of a few percent. In addition, they will probe for new physics via the search for evidence of anomalous couplings to the top quark and the measurements of additional bosonic contributions to single-top production. Methods developed to optimize the selection of single-top events in the three production channels are presented and the potential for the cross section measurements with 1 fb-1 and 30 fb-1 of integrated luminosity is established.
