Buying a building plot in or around Blairgowrie and Rattray? 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 Blairgowrie and Rattray area (12.19 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 1, flown 2011–2012 on a 1 m grid.
That survey is about 14 years old. Plots in Blairgowrie and Rattray 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 45.5 m and 161 m above Ordnance Datum, with a median of 67.2 m. The extremes (41 m to 188.1 m) can include water surfaces and data edges, so we don't quote them as ground levels.
That makes Blairgowrie and Rattray steep ground by Scottish town standards: about a quarter or more of it falls faster than 1 in 10. On slopes like that, the cut-and-fill estimate and the fall across the plot are often the numbers that change a build budget most, so they're worth seeing before an offer.
Fitting a plane through the 10 m levels, the ground across Blairgowrie and Rattray falls generally towards the south-east at about 19.1 m per km (roughly 1 in 52). The lowest tenth of the ground lies mostly to the east, and the highest tenth lies mostly to the north.
About 35.4% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 10.7°.
On SEPA's flood maps (medium likelihood), 4.5% of the Blairgowrie and Rattray extent is inside the river flood extent, 3.5% inside the surface water extent and none 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 128 listed building records in the extent (3 category A, 55 category B, 70 category C), and 8 scheduled monuments and 1 conservation area overlapping it. A plot report lists any that touch or sit near your boundary.
NatureScot protected areas overlapping the extent: River Tay (SAC).
None of the Blairgowrie and Rattray extent is within the Coal Authority's Development High Risk Area.
Nearest towns with pages here: Coupar Angus, 6.8 km south-east, median ground about 13 m lower; Alyth, 7.5 km north-east, median ground about 28 m higher; Kirriemuir, 22.5 km north-east, median ground about 80 m higher; Perth, 22.7 km south, median ground about 36 m lower.
Sampled every 10 m, the typical slope is 2.4°, and 25.7% 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.
