  We introduce an approach for calculating non-universal properties of rough
surfaces. The technique uses concepts of distinct surface-configuration
classes, defined by the surface growth rule. The key idea is a mapping between
discrete events that take place on the interface and its elementary local-site
configurations. We construct theoretical probability distributions of
deposition events at saturation for surfaces generated by selected growth
rules. These distributions are then used to compute measurable physical
quantities. Despite the neglect of temporal correlations, our approximate
analytical results are in very good agreement with numerical simulations. This
discrete-event analytic technique can be particularly useful when applied to
quantification problems, which are known to not be suited to continuum methods.
