CPEX grew from the 1998 initiative called Plan Baton Rouge. Plan Baton Rouge began as a program to oversee and implement a master plan for redeveloping downtown Baton Rouge. The downtown plan demonstrated the benefits of applying smart growth principles and leveraging public investment to catalyze new private investment. In 2005, in partnership with a new Hope VI development, Plan Baton Rouge completed a neighborhood plan for Old South Baton Rouge, a historic but disinvested community located between downtown and Louisiana State University. The plan focuses on revitalizing existing housing and businesses and integrating mixed-income housing and multi-use development to the area. CPEX continues to oversee implementation of both efforts.
Community/parish-scale planning
While working on the downtown and Old South Baton Rouge community plans, Plan Baton Rouge turned its attention toward parish issues by applying for the opportunity to receive an in-kind audit of East Baton Rouge Parish’s plan and related ordinances. In 2004, the Smart GrowthLeadership Institute and University of Southern California, funded by a grant from the US Environmental Protection Agency, selected Baton Rouge as one of nine cities in the nation to receive this service. The audit examined the Parish comprehensive plan, the Horizon Plan, to assess if this vision document promotes Smart Growth principles. The audit further assessed whether the legal ordinances contained in the Unified Development Code enable the parish to accomplish its Horizon Plan vision. With the recommendations of the audit, Baton Rouge is underway with revisions to the current codes to include new standards for development and new tools for encouraging "Smart Growth".
Regional planning
After hurricanes Katrina and Rita in 2005, CPEX began to play a larger role in planning efforts throughout the state of Louisiana. In January 2006, Plan Baton Rouge transitioned into the non-profit planning agency CPEX. CPEX coordinates the Louisiana Recovery Authority's statewide recovery planning process called Louisiana Speaks: Our Voice, Our Plan, Our Future. This initiative involved teams of consultants working at neighborhood, parish, and regional scales across South Louisiana. The long term recovery plan produced from this effort is the Louisiana Speaks Regional Plan. While working on the Louisiana Speaks regional vision, CPEX also received a grant from the EPA's Smart Growth division. Under this grant, CPEX has allocated funding, staff support and other resources to Tangipahoa Parish and West Feliciana Parish as they work to develop comprehensive plans that will address issues unique to Louisiana's rural communities.
