The Certified Local Government Program is a preservation partnership between local, state and national governments focused on promoting historic preservation at the grass roots level. The program is jointly administered by the National Park Service and the State Historic Preservation Office in each state, with each local community working through a certification process to become recognized as a Certified Local Government (CLG). CLGs then become an active partner in the Federal Historic Preservation Program and the opportunities it provides.
Having CLG status allows the City of St. Louis access to a wide network of partners in the world of historic preservation. The National Alliance of Preservation Commissions, Preserve America, National Trust for Historic Preservation, and the National Main Street Center. Being a CLG offers access to Federal funding that is specifically set aside for preservation projects. In the past, the City of St. Louis has used that source of money to fund architectural surveys, preservation plans, and National Register nominations.
