Blackline Development transforms overlooked, environmentally-impacted properties into clean, profitable, community-ready assets.
We take on the difficult sites, the ones others avoid, and bring together environmental expertise, legal strategy, and practical redevelopment solutions to unlock value where others see risk. Our mission is to remediate responsibly, develop intelligently, and create long-term returns for investors, municipalities, and the communities we serve.

Blackline Development was founded by two attorneys who spent their careers navigating the realities of contaminated land, regulatory pressure, and complex redevelopment projects. We built this company because we saw an opportunity in the properties everyone else walked away from - the brownfields, the forgotten industrial parcels, the environmentally challenged sites that demand more than a typical developer can deliver.
Our backgrounds in environmental law, land use permitting, and municipal strategy give us an unparalleled ability to manage risk, anticipate regulatory hurdles, and create clean, buildable land where others see only liability. We combine legal intelligence with practical, on the ground development experience to generate real value from the most challenging sites.
At our core, we believe that responsible remediation and smart redevelopment go hand in hand. That’s why Blackline exists: to create opportunity, restore land, and deliver high-quality projects that serve both investors and communities.
