One of the founding board members of GrowSmart Maine, Evan Richert began his professional planning career at GPCOG. Working with South Portland, he eventually left GPCOG to work full-time for the City. In 1981, he formed Portland Research and Communications and, shortly thereafter, joined with Mark Eyerman to form Market Decisions, Inc. (MDI). Together the team grew MDI into a premier consulting practice that bridged the gap between public planning and the development community. Anchoring planning, development, and public policy with direct market research and analysis, Evan demonstrated the importance of data in analyzing planning problems and identifying appropriate policies and strategies to address them.

In 1996, Evan became Director of the State Planning Office and led the State and its professional planners in developing a framework to understand and plan for Maine communities, regions and the state. Under his tutelage and using the that bully pulpit, Evan lead the State in a discussion and focus on the cost of sprawl, the importance and unique stresses of service center communities, and the importance of merging lines between land use, the environment, and the economy, He helped precipitate ongoing conversations about planning issues throughout the State from the Capitol to City Halls and neighborhood assemblies. Collaboration among the various sectors of the state — government organizations, chambers, NGOs, and professional associations – came together in unique ways that continue to affect how planners do business in Maine.

Reaching out to and inspiring professionals, as well as college and graduate students, Evan taught at the University of Southern Maine’s Muskie School for many years.

Over the years, Evan has received multiple awards that recognize his contribution to planning. To Maine’s planning community, Evan has been the “mind” of planning in Maine. He represents the analytical side of planning, reminding all that planning is immersed in facts, both hard statistics and scientific assessment, as well as in an understanding of cultural and social values. Evan’s gift is also the ability to translate complicated analysis in a way that not only informs, but touches the reader’s spirit.
