Understanding Flood Risk in Lagos
Which Lagos LGAs actually flood, why, and how flood risk should discount land you are about to buy.
The Lagos flood map, in 60 seconds
Lagos sits at 2–7m above sea level with a rising Atlantic and a lagoon system that backs up in the rains.
High-risk LGAs
- Lekki–Ajah axis (below-grade estates): tidal + rainfall flooding.
- Victoria Island (Oniru, Bar Beach): ocean surge + drainage.
- Ikoyi (Osborne, Parkview lowlands): stormwater.
- Ajegunle, Amukoko, Iwaya: informal drainage.
Medium-risk
- Yaba, Surulere, Ilupeju: episodic flash floods.
Lower-risk
- Ikeja GRA, Magodo Phase 2, Omole: better elevation, planned drainage.
What to discount
Buyers should model a 15–30% price discount on plots inside 100m of a documented flood corridor unless the developer has verified drainage and setback compliance. The Landigence Risk module quantifies this per parcel.
