The Sign Research Foundation (SRF) has published a four-page executive summary https://signresearch.org/wp-content/uploads/Best-Practices-in-Developing-Sign-Regulations-Executive-Summary.pdf of a research project conducted and written by Dr. Dawn Jourdan (Texas A&M), Dr. Eric Strauss (Michigan State) and Madeline Hunter. The work includes a survey of 17 communities with regard to citizen involvement (or the lack thereof) with regard to sign regulations.
Part of the summary states:
The “Best Practices in Developing Sign Regulations” report uses past literature to explore the role of citizen participation in the development of zoning regulations, noting that it has not been well documented. There’s been significant public discourse, and it’s generally accepted that inviting a variety of stakeholders to share in decision-making produces the best result. But barriers remain to effective and meaningful participation. Planners must carefully consider the degree to which stakeholder participation is important to the process, considering administration, objectives, targeting, techniques and other factors. In addition, the impact of collaboration with citizens must be evaluated. “It is often assumed that all citizen participation is good,” the report states, “but sometimes efforts to engage stakeholders can be counterproductive if not properly designed and managed.”
