“On Aire Ep. 15 w/ John DeHardt and John Peterson – The Art of Industrial Real Estate Podcast” featuring John DeHardt and John Peterson from Sunflower Redevelopment LLC
🔋 Unleashing Astra: Inside the Massive 6,000-Acre Megasite with Sunflower Redevelopment 🎙️ Episode 15 of On Air with Team
Jensen In the fifteenth episode of On Air with Team Jensen: The Art of Industrial Real Estate, the team hosts a true heavy-hitter roundtable featuring John DeHardt (Managing Partner of Kessinger Hunter) and John Peterson (“recovering attorney” and partner at Sunflower Redevelopment LLC). As the masterminds behind Astra Enterprise Park—the historic 6,000-acre project hosting Panasonic’s new multi-billion dollar EV battery plant—they pull back the curtain on a 19-year journey of complex environmental remediation, strategic partnerships, and massive infrastructure scaling.
🗺️ A Site the Size of a City
Originally a 9,000-acre active military munitions plant operating from WWII through Vietnam, Sunflower Redevelopment acquired the land from the U.S. Army nearly two decades ago. After executing public transfers of 3,000 acres to local park systems and state universities (KU and K-State), the team is left developing a staggering 6,000 contiguous acres. To put it in perspective, the site is roughly the same geographic footprint as the entire city of Leawood, Kansas.
⚡ An Energy Juggernaut: Mega-Substations and Solar
As power availability becomes a critical constraint for modern developers nationwide, Astra is uniquely positioned as a green energy leader. The southern half of the property—spanning roughly 3,000 acres—is being converted by developer Savion into one of the largest utility-scale solar arrays in the country, generating 450 to 500 megawatts of Renewable Power. To redistribute this energy alongside traditional high-voltage lines, local utility Evergy is actively constructing a massive, unprecedented 50-acre on-site substation.
“You need water, we have water. You need land, we have land. You need power, we have power. Oh, you want Renewable Power? We have Renewable Power.”
📜 Landmark Incentives: The Largest TIF in Kansas History
A key catalyst in securing Panasonic’s massive 4+ million-square-foot facility (which features 90 acres under a single roof) was a landmark annexation agreement with the nearby community of De Soto. By bringing the property into the city limits, Sunflower Redevelopment and local officials created the largest Tax Increment Financing (TIF) district in the history of the state of Kansas, providing an unparalleled deep well of economic incentives to attract further global mega-users.
🛤️ Key Infrastructure: Short-Line Rail and Water Rights
Astra boasts built-in, infrastructure assets that are nearly impossible to replicate. The development owns its own short-line rail corridor tying directly into the BNSF Main Line, with a formal freight service agreement nearing finalization. Additionally, the property maintains private water rights and a dedicated six-mile pipeline to the Kansas River, fueling an on-site, municipal water treatment expansion capable of meeting heavy industrial manufacturing demands on demand.
🥽 Overcoming the 19-Year Grind
Reflecting on the challenges, John Peterson notes that executing a private cleanup of a federal military site on this scale had never been attempted. Tearing down over 3,000 old structures and clearing vast tracts of land required close coordination with the Army, the EPA, and the KDHE. Today, with the physical remediation largely complete, the team is aggressively focused on the future, marketing the park toward data centers, aerospace, and high-tech manufacturers supported by a robust local pipeline of tech-focused engineering talent.
