Two years after her first appearance on The Hidden City Podcast, April Allen returns as Halperin Park prepares to officially open in Oak Cliff this weekend. Recorded inside the park just days before opening, this episode captures a full-circle moment for one of Dallas’ most ambitious community-led projects.

April, President & CEO of the Southern Gateway Public Green Foundation, shares what it took to bring the park from early renderings to reality, the emotional weight of reaching opening weekend, and how neighbors helped shape nearly every detail of the space. From the 12th Street Promenade reconnecting divided neighborhoods to the native landscaping, gathering spaces, and future plans for Phase Two, this conversation explores how Halperin Park was designed with Oak Cliff at its center. We also talk about opening weekend festivities, local partnerships, and why April believes this park will change how people experience both Oak Cliff and Dallas itself. This episode features sneak peeks of the new park, aerial footage, and an early look at one of Dallas’ most significant new public spaces.

Matt James, Chief Animal Officer at Colossal Biosciences and an Oak Cliff neighbor, joins The Hidden City to unpack one of the most ambitious ideas in modern conservation: making extinction a thing of the past. We talk about how Colossal uses genetic engineering, AI, and assisted reproduction to revive keystone species like the woolly mammoth and dire wolf — and why rewilding has the power to restore entire ecosystems. Matt shares what functional de-extinction really means, the ethical questions that come with it, and how these breakthrough technologies are already helping protect at-risk species today. We also trade notes on our favorite walkable Oak Cliff spots and what makes this neighborhood feel like home.

Chris Corpus, Senior Director of Conservation and Community Impact at the Dallas Zoo, joins us to talk about what it really means to care for wildlife—both in faraway ecosystems and right here in Oak Cliff. From creek cleanups and community partnerships to wildlife rescue and international conservation work, Chris shares how his journey from journalism and filmmaking led him to a career centered on people, place, and protecting what’s wild. Along the way, we dig into urban nature, global species recovery, and why empathy and education are at the heart of it all.
