Buying a building plot in or around Newport-on-Tay? 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 Newport-on-Tay area (12.32 km² from the OS Open Names extent), open LiDAR covers 83.6% of the ground. The best survey for most of it is LiDAR for Scotland Phase 5, flown 2021 on a 0.5 m grid (80.1% of the area).
Other parts use LiDAR for Scotland Phase 1, flown 2011–2012 (3.2%); LiDAR for Scotland Phase 4, flown 2020 (0.3%). 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 Newport-on-Tay 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 -0.9 m and 113 m above Ordnance Datum, with a median of 37.8 m. The extremes (-1.2 m to 123 m) can include water surfaces and data edges, so we don't quote them as ground levels.
That makes Newport-on-Tay 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.
Tiles from LiDAR for Scotland Phase 2 (DTM only) (flown 2012–2014) also overlap the Newport-on-Tay extent, but where surveys overlap the report uses the best one, as above.
Fitting a plane through the 10 m levels, the ground across Newport-on-Tay falls generally towards the north-west at about 26.5 m per km (roughly 1 in 38). The lowest tenth of the ground lies mostly to the north, and the highest tenth lies mostly to the south.
About 35.4% of the 10 m samples are flatter than 1 in 40, while one in ten is steeper than 12°.
On SEPA's flood maps (medium likelihood), none of the Newport-on-Tay extent is inside the river flood extent, 1.6% inside the surface water extent and 43.9% 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 57 listed building records in the extent (36 category B, 21 category C), and 3 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: Balmerino - Wormit Shore (SSSI); Inner Tay Estuary (SSSI); Firth of Tay and Eden Estuary (SAC); Firth of Tay and Eden Estuary (SPA); Firth of Tay and Eden Estuary (Ramsar site).
None of the Newport-on-Tay extent is within the Coal Authority's Development High Risk Area.
Nearest towns with pages here: Dundee, 2.8 km north-west, median ground about 24 m higher; Tayport, 3.9 km east, median ground about 27 m lower; Broughty Ferry, 5 km north-east, median ground about 8 m lower; Monifieth, 9.1 km north-east, median ground about 15 m lower.
Sampled every 10 m, the typical slope is 3.7°, and 34.8% 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.
