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. 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.
In general, the LI considers that it should be suitably qualified and experienced landscape professionals that carry out landscape and visual impact assessments (LVIAs). However, provided they have had appropriate training and experience, other professionals may also do so.
When it comes to reviewing assessments undertaken by others, however, in the absence of formal certification of specific competence, the appropriate ‘competent expert’ would normally be a Chartered Member of the Landscape Institute who has substantive experience of undertaking and reviewing LVIAs. This experience may be evidenced by CV, reference to previous assessments, and by endorsement by other senior professionals.
To assist those reviewing assessments (whether as part of a QA or Development Management process) the LI has published further guidance.
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. This is a small Panel with private and public sector representatives. Some are drawn from Technical Committee, some from those involved in the document’s production and any other vacancies by appointment following a competitive process. Vacancies are advertised either on the LI jobs website or via Technical newsletters.
The Panel is open to hear from LI members and regulators about their experiences with GLVIA3 as long as it is on the basis that not much more than an acknowledgement will initially be possible. Communications should be directed to firstname.lastname@example.org These will then be shared with the Panel at its next meeting and if there is the need to take action it will do so. Please note that a personal response may not always be possible, but submissions will be reviewed, and sometimes those contacting may be invited to speak to the Panel.
In December 2020, the LI held a webinar titled GLVIA Misconceptions and Best Practice. The session prompted a number of questions, which the GLVIA Panel has answered in this Technical Information Note. The document should be read alongside GLVIA3 and the statements of clarification, which can be found here.
