Headwaters Sanctuary has unveiled a 10-year master plan designed to balance increased public awareness with the protection of its 53-acre site. Developed by the Urban Alchemy Collective and funded by HEB, the proposal outlines new infrastructure and land management goals.
Why it matters
The plan aims to preserve the site's environmental integrity while enhancing the visitor experience for San Antonio residents. It addresses the growing need to manage ecological impact within a protected urban space.
The plan encompasses the entire 53-acre footprint of the sanctuary, which features the Blue Hole spring as its primary water source. Management aims to mitigate long-term ecological damage by adjusting existing trail paths to specifically manage erosion.
