Master Plan is intended to provide a rational basis for decisions concerning the restoration, preservation, improvement and expansion of the Capitol buildings and grounds. The Commission annually reviews the Master Plan and documents any updates in Master Plan Appendix D to keep the Plan current and useful as a guide to planning decisions. Appendix D is an ongoing summary of accomplished goals of the Plan, recognizing work completed and changed circumstances, if any, as well as documenting by amendment any modifications, with rationale, made to the Master Plan.
