What we do
Five practice areas covering every phase of land development.
Each section below maps directly to a working team inside Southland — same engineers from feasibility through final acceptance.
Single-Family Residential
We partner with builders and developers of every size to plan, entitle, design, and deliver single-family residential communities across Texas — from boutique infill to thousand-lot master-planned subdivisions.
- Feasibility & due-diligence studies
- Water, sewer, and storm utility design
- Platting & entitlements coordination
- Land planning & lot yield optimization
- Civil design development through bid set
Multi-Family & Mixed Use
Multi-family and mixed-use projects demand careful coordination of access, parking, utilities, and stormwater. We design solutions that hit pro-forma without compromising the architecture.
- Feasibility & site selection
- Wet and dry utility design
- Zoning analysis & PD support
- Land planning & site layout
- Site design through construction documents
Commercial
From single-pad retail to large-format industrial, we deliver commercial site design with construction-phase support so projects stay on schedule from groundbreaking to certificate of occupancy.
- Feasibility & site due diligence
- Utility design & coordination
- Zoning & variance analysis
- Land planning & traffic-circulation review
- Site design development & CD package
Hydrology & Hydraulics
Our H&H team protects communities from flooding and helps developers unlock challenging sites with rigorous hydrologic and hydraulic modeling, detention design, and floodplain analysis.
- Master drainage plans
- Hydrologic & hydraulic modeling (HEC-HMS, HEC-RAS)
- Stormwater management & SWPPP
- Detention & water quality pond design
- FEMA floodplain mapping & CLOMR/LOMR support
Construction Services
Design quality only matters if it gets built. Our construction services team carries projects through bid, administration, and inspection so what we drew is what gets installed.
- Bid phase assistance & contractor pre-qualification
- Construction administration & RFI response
- On-site inspection & punch list
- Quality assurance & material testing oversight
- Cost estimating & change-order review
