Plot levels in Blackburn

Buying a building plot in or around Blackburn? 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.

Source: Scottish Government LiDAR for Scotland Phase 1, flown 2011–2012; typical ±0.15 m on open ground in our tests. Flown 14 years ago; work done since then will not show.

What the open data says about Blackburn

Across the Blackburn area (1.93 km² from the OS Open Names extent), open LiDAR covers 0.2% 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 Blackburn 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 111.5 m and 123.4 m above Ordnance Datum, with a median of 118.5 m. The extremes (110.6 m to 124.1 m) can include water surfaces and data edges, so we don't quote them as ground levels.

That makes Blackburn 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 Blackburn falls generally towards the north-east at about 107.3 m per km (roughly 1 in 9). The lowest tenth of the ground lies mostly to the north-west, and the highest tenth lies mostly to the north-west.

About 0% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 7.7°.

On SEPA's flood maps (medium likelihood), 10.5% of the Blackburn extent is inside the river flood extent, 4.1% 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 4 listed building records in the extent (2 category B, 2 category C), and no scheduled monuments or conservation areas overlapping it. A plot report lists any that touch or sit near your boundary.

No NatureScot SSSI, SAC, SPA, Ramsar site or National Nature Reserve overlaps the Blackburn extent.

None of the Blackburn extent is within the Coal Authority's Development High Risk Area.

Nearest towns with pages here: Kintore, 5 km north-west, median ground about 62 m lower; Westhill, 5.7 km south, median ground about 10 m higher; Inverurie, 10.3 km north-west, median ground about 44 m lower; Aberdeen, 13.3 km south-east.

Sampled every 10 m, the typical slope is 5.7°, and 46.7% 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.
