This article presents a new procedure for constructing fair legislative district maps. This straightforward, transparent, research-based procedure is intended to be helpful to those interested in promoting fair legislative district maps. The work draws upon a recent award-winning study of preferences of redistricting experts and lay citizens, alike. The approach draws upon that study to construct foundational legislative district maps. The mapping procedure then builds on that foundation, employing the well-established concept of partisan symmetry to construct maps that are fair to both major political parties. The article opens by discussing this new view of compact districts and describes the procedure for constructing the maps. Foundational maps are drawn for 12 states that have recently been under court scrutiny. Partisan symmetry is then applied to these maps to construct legislative district maps that are fair and square
