Buying a building plot in or around St Andrews? See how the ground falls and what constraints apply before you commit, using the Scottish Government LiDAR flown over the area and published on the Scottish Remote Sensing Portal.
Across the St Andrews area (9.68 km² from the OS Open Names extent), open LiDAR covers 100% of the ground. The best survey for most of it is LiDAR for Scotland Phase 5, flown 2021 on a 0.5 m grid (55.2% of the area).
Other parts use Scotland National LiDAR Programme, flown 2025–2026 (44.8%). A plot near the join between surveys may draw on both; the report shows which survey covers each part of your boundary.
That survey is about 5 years old. Plots in St Andrews that have been cleared, filled or built on since then won't show those changes, so the report flags the date at the top of every page and checks for buildings mapped since the flight where it can.
Most of the ground across the area (96% of readings) lies between -0.6 m and 62.6 m above Ordnance Datum, with a median of 25.2 m. The extremes (-2.1 m to 68.3 m) can include water surfaces and data edges, so we don't quote them as ground levels.
Much of St Andrews is gently sloping, with steeper banks in places (13.9% over 1 in 10). Two plots a street apart can differ a lot, so the plot-level contours matter more than the town average.
Parts of the area are less than 5 m above Ordnance Datum, so a plot report here also lists whether SEPA's mapped flood extents touch the boundary. That is a map layer, not a flood risk assessment.
Tiles from LiDAR for Scotland Phase 4 (flown 2020); LiDAR for Scotland Phase 2 (DTM only) (flown 2012–2014); LiDAR for Scotland Phase 1 (flown 2011–2012) also overlap the St Andrews extent, but where surveys overlap the report uses the best one, as above.
Fitting a plane through the 10 m levels, the ground across St Andrews falls generally towards the north-east at about 19.4 m per km (roughly 1 in 52). The lowest tenth of the ground lies mostly to the north-east, and the highest tenth lies mostly to the south-west.
About 36.9% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 6.9°.
On SEPA's flood maps (medium likelihood), 4.6% of the St Andrews extent is inside the river flood extent, 4.4% inside the surface water extent and 11.4% inside the coastal extent. The extent is a rectangle round the town, so it can take in foreshore, sea and open ground. These are indicative national maps, not a flood risk assessment; a plot report gives the figures for your own boundary.
Historic Environment Scotland has 531 listed building records in the extent (26 category A, 237 category B, 268 category C), and 4 scheduled monuments, 2 conservation areas and 3 inventory gardens and designed landscapes overlapping it. A plot report lists any that touch or sit near your boundary.
NatureScot protected areas overlapping the extent: Eden Estuary (SSSI); Firth of Tay and Eden Estuary (SAC); Firth of Tay and Eden Estuary (SPA); Outer Firth of Forth and St Andrews Bay Complex (SPA); Firth of Tay and Eden Estuary (Ramsar site).
0.1% of the extent lies within the Coal Authority's Development High Risk Area (where recorded past coal mining features are present).
Nearest towns with pages here: Tayport, 13 km north-west, median ground about 14 m lower; Cupar, 13.6 km west, median ground about 16 m higher; Crail, 13.6 km south-east, median ground about the same; Anstruther, 14.1 km south-east, median ground about 9 m lower.
Sampled every 10 m, the typical slope is 1.9°, and 13.9% of the area is steeper than 1 in 10. A single plot can be much flatter or steeper than this. Its report works at 0.5 m.

Read from the open LiDAR at a 10 m sample on 2026-10-23; local data checked 2026-10-23. A plot report reads the same data at 0.5 m for your boundary only.
Accuracy. We test Scottish LiDAR against independent survey overlaps and Ordnance Survey levelled trig pillars: heights are ±0.14 m typical on open ground (95% within ±0.28 m). Results by survey phase.
