We study upgrade paths to significantly reduce the emittance of SPEAR3, a 3 GeV 3rd generation light source. The lattice potential is explored with global search techniques. Several candidate lattices are designed and studied in simulation and are implemented on the real machine. We employ genetic algorithms to optimize the nonlinear dynamics of the new lattices with various combinations of knobs. Plans for hardware upgrade for this project will be discussed.
