We reinvestigate the utility of time-independent constant mean curvature fo
liations for the numerical simulation of a single spherically symmetric bla
ck hole. Each spacelike hypersurface of such a foliation is endowed with th
e same constant value of the trace of the extrinsic curvature tensor K. Of
the three families of K-constant surfaces possible (classified according to
their asymptotic behaviors), we single out a subfamily of singularity avoi
ding surfaces that may be particularly useful, and provide an analytic expr
ession for the closest approach such surfaces make to the singularity. We t
hen utilize a nonzero shift to yield families of K-constant surfaces which
(1) avoid the black hole singularity, and thus the need to excise the singu
larity, (2) are asymptotically null, aiding in gravity wave extraction, (3)
cover the physically relevant part of the spacetime, (4) are well behaved
(regular) across the horizon, and (5) are static under evolution, and there
fore have no "grid stretching/sucking" pathologies. Preliminary numerical r
uns demonstrate that we can stably evolve a single spherically symmetric st
atic black hole using this foliation. We wish to emphasize that this coordi
natization produces K-constant surfaces for a single black hole spacetime t
hat are regular, static, and stable throughout their evolution.
