Plot levels in Ceann Loch Gilb

Buying a building plot in or around Ceann Loch Gilb? 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 Ceann Loch Gilb

Across the Ceann Loch Gilb area (6.12 km² from the OS Open Names extent), open LiDAR covers 75.7% of the ground. The best survey for most of it is LiDAR for Scotland Phase 1, flown 2011–2012 on a 0.999994 m grid.

That survey is about 14 years old. Plots in Ceann Loch Gilb 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 1.1 m and 69.4 m above Ordnance Datum, with a median of 10.5 m. The extremes (0.9 m to 98.4 m) can include water surfaces and data edges, so we don't quote them as ground levels.

That makes Ceann Loch Gilb 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.

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.

Fitting a plane through the 10 m levels, the ground across Ceann Loch Gilb falls generally towards the south-west at about 27 m per km (roughly 1 in 37). The lowest tenth of the ground lies mostly to the south-west, and the highest tenth lies mostly to the north.

About 36.1% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 9.3°.

On SEPA's flood maps (medium likelihood), 4.5% of the Ceann Loch Gilb extent is inside the river flood extent, 4% inside the surface water extent and 25.3% 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 34 listed building records in the extent (21 category B, 13 category C), and 2 scheduled monuments and 1 conservation area 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 Ceann Loch Gilb extent.

None of the Ceann Loch Gilb extent is within the Coal Authority's Development High Risk Area.

Nearest towns with pages here: Inbhir Aora, 31 km north-east, median ground about 5 m higher; Rothesay, 32.7 km south-east, median ground about 24 m higher; Dunoon, 32.9 km east; Gourock, 39.3 km east, median ground about 47 m higher.

Sampled every 10 m, the typical slope is 3.6°, and 30% 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.
