San Gabriel Unitarian Universalist Fellowship

Priorities: Accessible Circulation – Stormwater Management – Durable Outdoor Space
Challenges: Flood-Prone Site – Off-Site Runoff – Precise Grade Transitions
Solutions: ADA-Compliant Sidewalk and Ramp – High-Capacity French Drain – Rain Gardens and Custom Drain Box

Located near historic Old Town in Georgetown, Texas, San Gabriel UU Fellowship serves a diverse community and prioritizes accessibility for people of all ages and mobility levels. Maas Verde Landscape Restoration was engaged to construct a new concrete sidewalk, a large deck, and a comprehensive stormwater management system that aligned with the fellowship’s inclusive values.

The site presented significant drainage challenges, including heavy runoff from two off-site church parking lots that routinely flooded the construction area during rain events. To address this, Maas Verde fabricated a custom 24-inch³ concrete drain box off-site capable of handling large volumes of stormwater. A high-capacity French drain system was designed and installed to move water efficiently through the site.

Downstream of the deck, Maas Verde constructed two rain gardens to slow, capture, and absorb runoff at multiple points, reducing pressure on the drainage system while allowing water to infiltrate naturally into the soil. Careful grading ensured the deck and sidewalk aligned seamlessly, meeting ADA requirements and incorporating a ramp to provide safe, comfortable access for all visitors.

By mitigating impervious surfaces and integrating natural stormwater catchment areas, this project balances durable construction with ecological design, delivering a functional and inclusive outdoor environment.
