Culverts - Scotland

Scottish legislation (Section 17) of the Flood Risk Management (Scotland) Act 2009 dictates that records of culverts must be created and maintained. Specifically:

(1) Every local authority must prepare a map which shows (or more than one map which, taken together, show) relevant bodies of water and sustainable urban drainage systems in its area.

(2) Each map must -

(a) be prepared by such date as the Scottish Ministers may direct,

(b) be prepared at a scale that the authority considers most appropriate, and

(c) contain such information and be in such form as the Scottish Ministers may

specify in regulations.

(3) A local authority must, from time to time, review and where appropriate update the map (or maps) prepared for its area under subsection (1).

(4) A local authority must make available for public inspection the map (or maps) prepared under this section for the time being applicable to its area.

(5) In this section and section 18 - “relevant body of water” -

(a) means -

(i) a body of surface water other than a stretch of coastal water, or

(ii) a body of underground water forming part of a watercourse (but not

including a watercourse which is wholly underground), but

(b) does not include sewers and drains which drain into sewers, “sustainable

urban drainage system” has the meaning given in section 59(1) of the

Sewerage (Scotland) Act 1968 (c.47).

Most Local Authorities have contributed (natural) culvert data to the new OS MasterMap Water Network Layer either through providing data to the Scottish Government or through the James Hutton Institute. As this data is now live, a mechanism for managing/maintaining/updating this data needs to be put in place. SCOTS (Society of Chief Officers for Transportation in Scotland) have approved for this dataset to be managed by the Spatial Hub and any amended data can be uploaded (and potentially downloaded) before being shared with OSMA members and the OS.

We have initially created a point and line data layer representing the data we have been sent by some LAs. However, we really need line data in order for it to be merged into the OS MasterMap Water Network Layer data in due course.

The LA "culverts" data as included in the OS MasterMap Water Network Layer is also available for LAs to download and use as part of this dataset

Statement

This dataset was amalgamated, optimised and published by the Spatial hub.

The following quality assurance checks and corrections are carried out on the data:

- Polygons are not dissolved/ aggregated by key name and local authority.

- The minimum polygon area allows in the data is 1 square metres

- Checks for invalid geometry types

- The maximum angle for any spikes is 3 degrees

- Any duplicate geometry is removed from the data

- Duplicate key names for polygons are not removed

- Polygons with no key names are not removed

- Checks for basic geometry and self-intersection

Please contact spatialhub@improvementservice.org.uk for more details.
