Landscape Architect San Antonio
San Antonio Landscape Architecture for Developers, Engineers, and Architects
Evergreen Design Group is a landscape architect San Antonio developers, civil engineers, architects, and design-build contractors rely on for projects across San Antonio and the broader Bexar County market. Headquartered in Bluffton, South Carolina, offering landscape architecture services nationwide and licensed in 43 states, Evergreen Design Group has delivered land planning, planting design, hardscape design, and irrigation design since 2005 on residential communities, mixed-use developments, commercial projects, and institutional sites throughout the San Antonio metro.
San Antonio is a complex and distinctive landscape architecture market — shaped by the Edwards Aquifer’s dominance over water availability and regulatory structure, SAWS water conservation requirements that are among the most detailed in Texas, the city’s limestone karst geology, and a significant institutional and military-adjacent development sector. The San Antonio metro’s growth — extending into Comal County (New Braunfels), Guadalupe County (Seguin, Schertz), Wilson County, and Atascosa County — adds suburban regulatory complexity to a market that is already demanding within the city limits.
Landscape Architecture in San Antonio's Development Environment
San Antonio Water System (SAWS) Water Conservation Requirements
San Antonio Water System (SAWS) irrigation plan review requirements administers one of the most detailed outdoor water conservation programs of any major Texas utility. SAWS's water conservation landscape requirements for new commercial and multifamily development include: maximum turf area as a percentage of total landscaped area, minimum drought-tolerant plant coverage requirements, mandatory weather-based smart irrigation controller technology, and restrictions on spray irrigation in planted areas in favor of drip emitter systems. SAWS reviews irrigation plans as part of the permit process and enforces outdoor watering schedules during drought conditions through a tiered restriction program.
San Antonio's water conservation requirements are driven by the Edwards Aquifer — the primary drinking water source for the city and surrounding communities. SAWS's long-term water management strategy depends on reducing per-capita outdoor water use, and the conservation requirements for new development reflect that strategic priority. Landscape architects designing in San Antonio must produce planting and irrigation plans that satisfy SAWS requirements from the start — plans that don't address conservation requirements generate SAWS plan review corrections.
Edwards Aquifer in San Antonio: Recharge Zone and Aquifer Zone
San Antonio sits directly over the artesian portion of the Edwards Aquifer, and the city's growth corridors to the north and west extend into the Edwards Aquifer Recharge Zone — the primary zone where surface water infiltrates to recharge the aquifer. The Edwards Aquifer Authority (EAA) administers impervious cover limitations and water quality protection requirements for development in the Recharge Zone, with impervious cover caps that restrict the percentage of a site that can be covered by buildings, pavement, and other impervious surfaces.
Northwest San Antonio growth corridors — particularly areas along Loop 1604, US-281 north, and TX-16 — sit in or adjacent to the Recharge Zone, where development must comply with EAA impervious cover requirements in addition to the city's land development code and SAWS conservation standards. Landscape architects on Recharge Zone projects must maximize permeable landscape area, consider permeable paving alternatives that count against impervious cover calculations, and design stormwater management appropriate to karst hydrology.
San Antonio's Tree Preservation Ordinance
San Antonio administers a tree preservation ordinance through the Development Services Department that requires tree surveys and mitigation documentation for development projects within city limits. The ordinance protects heritage trees — defined by species and diameter — and requires replacement or in-lieu-fee payment for protected trees that must be removed. San Antonio's significant heritage live oak population, particularly in established neighborhoods on the city's north and northwest sides, creates tree preservation constraints on infill and redevelopment sites. Heritage live oak trees, with their large canopy spreads and extensive root systems, can significantly constrain site layout and grading.
San Antonio Unified Development Code Landscape Standards
San Antonio's Unified Development Code (UDC) establishes landscape standards applicable to new development and significant redevelopment within city limits, including minimum landscape area requirements, parking lot tree coverage standards, street tree requirements, buffer yard planting standards, and water-efficient landscaping provisions aligned with SAWS conservation requirements. The UDC landscape standards are reviewed by Development Services as part of site plan approval, and coordination between UDC landscape requirements and SAWS irrigation plan review is a standard part of the San Antonio permitting process.
San Antonio Suburban Growth Markets: Comal, Guadalupe, and Surrounding Counties
San Antonio's growth extends into several surrounding counties with distinct regulatory environments:
- Comal County (New Braunfels, Schertz, Cibolo): One of the fastest-growing counties in the United States, driven by San Antonio and Austin metro expansion. New Braunfels administers its own landscape and tree standards; Schertz and Cibolo have their own municipal ordinances. The Edwards Aquifer recharge zone extends into parts of Comal County, adding EAA constraints to development in affected areas.
- Guadalupe County (Seguin, Schertz, Marion): Active residential and commercial growth; Schertz spans the Bexar-Comal-Guadalupe county boundary and administers unified city ordinances across all three counties.
- Medina County and Bandera County (western growth corridors): Emerging exurban residential markets on San Antonio's west and northwest; primarily county-regulated with individual city ordinances in incorporated areas.
- Wilson County and Atascosa County (southern growth corridors): Early-stage suburban development south of San Antonio with active land planning activity.
Military-Adjacent and Institutional Development
San Antonio is home to the most concentrated collection of U.S. military installations in the country — Joint Base San Antonio (Fort Sam Houston, Lackland AFB, Randolph AFB), plus Camp Bullis training areas. Military-adjacent development — housing, commercial, medical, and support facilities — generates significant landscape architecture demand in the communities surrounding JBSA. We serve institutional and military-adjacent projects with the documentation standards and coordination practices that public and institutional project delivery requires.
Landscape Architecture Services We Deliver in San Antonio
Every service is performed in-house by our licensed professionals with no subcontracting of scope.
Our land planning services in San Antonio must integrate Edwards Aquifer Recharge Zone impervious cover constraints, SAWS conservation requirements, heritage tree protection areas, and floodplain buffers along the city’s numerous creeks before the civil plan is set. We engage with developers and civil engineers at the pre-application stage to establish site organization that respects these constraints from the beginning — integrating impervious cover management, tree preservation, and stormwater feature siting into the conceptual plan before costly redesign is required.
Planting design in San Antonio is defined by limestone karst geology, thin rocky soils in the Hill Country transitional areas northwest of the city, deeper clay soils in the eastern and southern sectors, high summer heat and drought stress, and SAWS conservation requirements mandating drought-tolerant plant species in a minimum percentage of planted area. Native South Texas and Hill Country plant palettes — live oak, Texas mountain laurel, cenizo, native grasses, drought-tolerant perennials — form the foundation for planting designs that satisfy SAWS standards and perform in San Antonio’s climate with minimal irrigation after establishment.
San Antonio’s tree preservation ordinance and the distinct tree requirements of Comal County municipalities (New Braunfels) and other suburban jurisdictions require tree documentation calibrated to each applicable local ordinance. We produce tree disposition plans to the applicable local standard, with early engagement on heritage live oak preservation strategy — live oaks’ large root systems and canopy spreads make preservation planning a land planning-stage activity, not a construction document afterthought.
San Antonio’s residential development market — in the fast-growing corridors along US-281 north, Loop 1604, and in Comal and Guadalupe counties — demands competitive amenity packages. The city’s significant military family population and large institutional workforce create a residential market with strong demand for family-oriented amenity facilities: pools, clubhouses, trail systems, dog parks, and community gathering spaces. We design amenity packages that reflect San Antonio market expectations and are SAWS-compliant in their landscape water use design.
Hardscape design in San Antonio spans the geological transition from limestone bedrock in the northwest to heavier clay soils in the east and south. Limestone substrate proximity limits excavation depth on many sites and creates drainage challenges that conventional detention approaches may not adequately address in karst terrain. Summer heat is extreme — surface temperatures on pavement can reach 140-160°F — making material selection and shading strategy important for pedestrian comfort. We produce fully documented hardscape construction drawings calibrated to San Antonio’s geological and climate conditions.
Irrigation design in San Antonio is the most heavily regulated landscape architecture deliverable in the market — shaped by SAWS conservation requirements (maximum turf area, drip irrigation mandates in planted beds, smart controller requirements), TCEQ irrigation licensing requirements, and the practical imperative of designing systems that minimize water use from the Edwards Aquifer. We provide irrigation design services that satisfy SAWS plan review requirements, are documented to TCEQ standards, and are engineered for the water use efficiency that San Antonio’s conservation environment demands.
Frequently Asked Questions — San Antonio Landscape Architects
What are San Antonio Water System's (SAWS) landscape and irrigation requirements for new development?
SAWS administers detailed outdoor water conservation requirements for new commercial and multifamily development in San Antonio. Requirements include: a maximum percentage of total landscaped area that can be planted with high-water-demand turf grass, a minimum percentage of planted area that must be planted with drought-tolerant or native species, mandatory weather-based smart irrigation controller technology, and restrictions on spray irrigation in planted beds (requiring drip emitter systems instead in many applications). SAWS reviews irrigation plans as part of the permit process separate from the city’s standard site plan review — both the UDC landscape plan review and the SAWS irrigation plan review must be satisfied before permits are issued. We produce planting and irrigation documentation that satisfies both review processes.
How does the Edwards Aquifer Recharge Zone affect development in the San Antonio area?
The Edwards Aquifer Recharge Zone underlies San Antonio’s northwest growth corridors and significant portions of Comal and Medina counties. Edwards Aquifer Authority’s groundwater protection program administers impervious cover limitations in the Recharge Zone — caps on the percentage of a site that can be covered by impervious surfaces — to protect the groundwater quality of the aquifer that provides drinking water to approximately 2 million people. Development in the Recharge Zone must comply with EAA impervious cover requirements in addition to city landscape ordinance and SAWS conservation standards. Landscape architects on Recharge Zone projects must maximize permeable landscape area, evaluate permeable paving alternatives, and design stormwater management appropriate to karst terrain. The interaction of EAA, city UDC, and SAWS requirements on Recharge Zone sites requires integrated design from the earliest planning stage.
What does San Antonio's heritage tree ordinance protect, and how does it affect development?
San Antonio’s tree preservation ordinance protects heritage trees — defined by species and diameter threshold — requiring surveys, protection documentation, and mitigation (replacement or in-lieu payment) for protected trees removed during development. The city’s significant heritage live oak population, particularly in northwest San Antonio’s established neighborhoods and along creek corridors, creates meaningful constraints on infill and redevelopment sites. Heritage live oaks’ large canopy spreads and extensive lateral root systems establish critical root zones that must be respected in grading, paving, and utility design. We engage with tree preservation strategy at the land planning stage — before the civil plan is set — to ensure that heritage tree locations are integrated into site organization decisions rather than discovered as constraints after the fact.
Do you serve projects in New Braunfels, Schertz, Cibolo, and other San Antonio suburbs?
Yes. The San Antonio metro’s growth is concentrated in the surrounding counties, particularly Comal County (New Braunfels, Schertz) — one of the fastest-growing counties in the country — and Guadalupe County (Schertz, Seguin). Each municipality administers its own landscape and tree ordinance requirements distinct from San Antonio’s UDC. The Edwards Aquifer Recharge Zone extends into parts of Comal County, adding EAA constraints to some suburban projects. We maintain current working knowledge of the landscape requirements of the major San Antonio suburban jurisdictions and design to the applicable local standard for each project.
How do we get started on a San Antonio project?
Contact us through our website or call our office. We will schedule a brief discovery call to understand your project type, site location, regulatory context — including Edwards Aquifer zone, SAWS requirements, and heritage tree situation — and schedule, and follow up with a proposal.
What licensing does a landscape architect San Antonio TX developers list on Edwards Aquifer Authority and SAWS permit submittals need to hold?
Plans submitted to the Edwards Aquifer Authority, SAWS, and the City of San Antonio’s Development Services Department must be prepared and sealed by a landscape architect holding an active Texas landscape architect registration. Evergreen Design Group holds that registration and is licensed in 43 states nationally, which matters on San Antonio projects where the design team often includes out-of-state developers or institutional owners who need a single, nationally licensed firm rather than a different regional consultant on every site. We prepare and seal the landscape, planting, and irrigation documentation required across the EAA, SAWS, and UDC review tracks.
How do you sequence SAWS irrigation plan review against the City's UDC landscape plan review on a San Antonio project?
The two reviews run on separate tracks and both must clear before permits are issued. We typically prepare the UDC landscape plan for Development Services review first, since it establishes the planting layout and turf area calculations that the SAWS irrigation plan is built around. Once the landscape plan is stamped, we finalize the irrigation design — smart controller specifications, drip zone layout, and turf area compliance — for SAWS’s separate conservation review. Running the two in that order avoids the most common cause of SAWS plan review corrections: an irrigation plan that no longer matches a landscape plan that changed after irrigation design was already underway.
