Surveying and Mapping

Question 1

What are the essential elements of a professional site plan or map?

Answer 1

A professional site map must be drawn to scale and include key elements such as:

A title describing the content and location

A scale bar or written scale (e.g. 1:1,250 or 1:2,500)

A north point to show orientation

A legend or key if symbols or colour coding are used.

Question 2

How do you determine site boundaries and land ownership when assessing development potential?

Answer 2

I primarily use Land Registry title plans and register entries to confirm legal ownership and boundary extents. These plans are usually based on OS mapping at 1:1,250 or 1:2,500 scale. However, I recognise that:

Boundaries shown are not definitive due to OS map generalisation

Older titles may not have precise boundary mapping

In unregistered areas, historic conveyances or legal descriptions may be needed.

Question 3

What is the purpose of using historic OS maps in site assessment?

Answer 3

Historic OS maps are valuable for understanding previous land uses, which can:

Indicate potential contamination risks (e.g. former industrial or landfill sites)

Reveal previous site boundaries, infrastructure, or buildings

Help establish context for heritage or archaeology assessments.

Question 4

How do Local Plan policy maps assist in site promotion or assessment?

Answer 4

Local Plan policy maps show land-use designations, such as:

Green Belt
Local Green Space
Settlement boundaries
Flood zones or environmental constraints

Question 5

What are common scales for maps used in planning and development?

Answer 5

The most common OS map scales are:

1:1,250 – urban areas

1:2,500 – rural
