GLVIA3

Guidelines for Landscape and Visual Impact Assessment (GLVIA3)

The third edition of Guidelines for Landscape and Visual Impact Assessment (GLVIA3) was published in collaboration with IEMA and came into force on 17 April 2013.

This is a key resource for landscape professionals. In general, suitably qualified and experienced landscape professionals should carry out and review landscape and visual impact assessments. However, provided they have had appropriate training and experience, other professionals may also do so.

Copies of the book can be ordered direct from the publisher. Although PDF versions are not available, other digital versions are, in the form of: ebook | Kindle.

GLVIA3 Panel

The GLVIA3 Panel continues to meet periodically to discuss issues relating to LVIA and when necessary publishes important clarifications relating to the book which are available free of charge.

GLVIA2

GLVIA3 replaces the second edition GLVIA2. In general terms, the approach and methodologies in the new edition are the same. The main difference is that GLVIA3 places greater emphasis on professional judgement and less emphasis on a formulaic approach. And all new assessments should be based on GLVIA3.

Members have asked for clarification on the status of projects developed under GLVIA2, but reviewed or implemented after publication of the third edition. LI Technical Committee’s view is that an assessment started using GLVIA2 should be completed using that edition. However, if in the view of the professional a comparison should be undertaken with GLVIA3, and subsequently if necessary a re-assessment undertaken according to GLVIA3, then this should be discussed and agreed with the client in the first instance.
