As regional challenges outgrow city boundaries, “When Borders Blur” explores how cross-jurisdictional collaboration can drive smarter, more resilient urban planning, sharing real-world lessons from thriving partnerships across North America.

In “When Borders Blur,” Susan Henderson of PlaceMakers illustrates how regional collaboration has become essential in addressing today’s complex planning challenges. She highlights the increasing need for planners to think beyond political boundaries, drawing from real-world examples where partnerships between neighboring cities, counties, and even states have led to more adaptive, resilient, and sustainable outcomes.
Rather than focusing solely on formal regional government structures, Henderson emphasizes the power of informal alliances — fueled by shared visions and mutual needs — that foster innovation and responsiveness where traditional governance models often fall short. Through vivid storytelling and accessible insights, she makes the case that the most successful collaborations begin with relationships, trust-building, and a commitment to collective benefit, not just compliance.
By weaving together examples ranging from transportation to water management and housing, Henderson invites planners, policymakers, and advocates to reimagine their roles as regional stewards. The piece serves as a timely call to action for those seeking to bridge divides and shape more resilient futures through cooperation.
