Stone Oak Quarry Could Become Walkable Mini District Under New City Draft

The City of San Antonio is floating a new public discussion draft that would, over the long haul, turn the San Pedro quarry in Stone Oak into a walkable mixed-use district once mining wraps up. The proposal sketches out clusters of housing, retail, and offices along major corridors, paired with infrastructure upgrades and protections for the local aquifer.

According to the San Antonio Business Journal, the draft leans on walkable, mixed-use hubs centered on key arterials, steering new growth away from quieter residential streets. The coverage notes that planners are trying to preserve the suburban feel that Stone Oak residents expect while channeling higher intensity development into specific corridors and nodes instead of scattering it through existing neighborhoods.

Quarry site and timeline

The quarry in question is Martin Marietta's San Pedro Quarry, an active aggregate operation on U.S. 281 that lists its facility at 19265 U.S. 281 N. Martin Marietta currently lists the location as an operating quarry, while the existing-conditions section of the Stone Oak Area Regional Center Plan describes the property as a quarry that "provides a unique future redevelopment opportunity" that would only come into play after reclamation and closure.

Water, infrastructure and neighborhood concerns

Planners repeatedly emphasize that any future reuse of the site would have to protect the Edwards Aquifer and be tied to targeted infrastructure funding so that traffic congestion does not get even worse, a priority flagged by the San Antonio Business Journal. The worry is not abstract, as KSAT has chronicled persistent bumper to bumper conditions in the area. Concentrating new density along major arterials could help curb sprawl, planners argue, but only if it is paired with staged infrastructure upgrades and genuine community buy in.

Public input and next steps

City staff plan to collect public feedback at an open house on Thursday, March 26, from 5:30 to 7:30 p.m. at Methodist Hospital Stone Oak, and residents can comment on the public discussion draft through April 26. The Stone Oak Area Regional Center Plan website lists project manager Jacob Howard and contact details for questions, and staff say they will review all comments before finalizing recommendations for the area.
