Site Surgery™ Framework / 01
Reframing Residential Landscape as Hydrological Infrastructure
Site Surgery™ is a landscape framework that redefines residential ground as decentralized hydrological infrastructure.
Rather than treating gardens as decorative surfaces, the framework approaches landscape as an operational system where soil, slope, runoff behavior, and construction logic are calibrated together through hydrological performance.
At the center of the framework is Hydrological Storage Capacity (HSC) — a metric that shifts landscape assessment away from purely visual area calculations and toward the site’s capacity to absorb, retain, redirect, and regulate water.
The framework emerged through design-led construction practice across residential landscapes in Australia, where increasingly volatile rainfall events, concentrated runoff, erosion, and hydrostatic pressure have exposed the limitations of conventional drainage-based approaches.
Instead of removing water as quickly as possible, Site Surgery™ slows, redistributes, stores, and processes water through a system, operates as a network of Site Hydrological Nodes (SHN).
Each SHN performs a specialized hydrological role based on site conditions including slope, soil permeability, rainfall intensity, and structural pressure.
The current framework operates through four primary node typologies:
SHN-F
Low-Gradient Infiltration Node
SHN-S
Gradient Interception Node
SHN-R
Structural Pressure-Relief Node
SHN-E
Interface Transition Node
Together, these nodes form a distributed hydrological network capable of moderating runoff velocity, stabilizing soil systems, reducing hydrostatic buildup, and improving long-term landscape resilience.
Site Surgery™ is currently being developed through high-end residential pilot projects as an evolving technical framework for future climate-responsive landscape infrastructure.
