We reference SANRAL and municipal geometric constraints where applicable to the road authority. In Johannesburg, High-intensity convective storms over urbanised catchments increase peak flows; legacy mining infrastructure and dolomitic areas add complexity. Our team supports projects across Gauteng with studies scoped for municipal and DWS review cycles.
Johannesburg sits within Gauteng, where Johannesburg and Ekurhuleni municipal stormwater frameworks influence floodline and stormwater submissions for greenfield and infill projects. For this service, we emphasise defensible hydrology, clear assumptions, and deliverables that integrate with your professional team—survey, civils, and environmental practitioners—so approvals move without rework.
When do you need this?
- Road upgrades with constrained headwater or debris risk
- Multi-cell crossings and complex inlet configurations
- Fish passage or environmental constraints on crossings
