Landscape Visual Impact Assessment (LVIA)

A Landscape Visual Impact Assessment (LVIA) will be needed for large developments and developments which could impact on the wider landscape or on a protected landscape such as a National Park or an Area of Outstanding Natural Beauty (AONB.)

Establishing a baseline assessment; scoping is the first stage of an Landscape and Visual Impact Assessment (LVIA.) This reviews the existing landscape character and landscape resource. It is a part of the methodology to discuss possible viewpoints of the proposed development with the local authority Landscape Architect.  We find it useful to do this at an early stage in the formulation of the LVIA.  The use of  plans, online data, maps, Landscape Management Plans and Landscape Character classification and analysis are key to obtaining an understanding of  visual impact of a proposed development.  It can also be useful to prepare a Zone of Visual Influence map (ZTI) or Zone of Theoretical Visibility (ZTV.) These maps use a digital approach to mapping visibility. It is recommended that buildings and vegetation, are not taken into account when producing a ZTI map for a Landscape Visual Impact Assessment.

Visual receptors are a part of the Landscape visual impact assessment report analysis. Landvision will analyse the likely views from key viewpoints. During the site visit we will note visual receptors and their location. This helps us to understand how the landscape is used at present. We also take photos using a digital SLR, recording location and view.  These photos will be an important part of the Landscape Visual Impact Assessment report. You will be advised on how your proposals can respond to the findings of the LVIA. Landvision will advise you on any landscape mitigation required. We often stitch photos together and can create a visual representation of your proposed development.

Landvision’s team of landscape architects provide LVIA input by;

Baseline assessment and feasibility studies.
Assessment of visual impacts.
Sensitivity of landscape and Visual receptors.
Zone of Visual Influence (ZVI.)
Photomontages.
Nature of impact.
Significance of Visual Impact.
Visual Resource Change Magnitude.

Landscape Visual Impact Assessment Methodology and Good Practice.

What are the long term aims and results of a thorough working knowledge of LVIA? Landvision’s Landscape and Visual Impact Assessment (LVIA) can become part of an Environmental Impact assessment (EIA); the LVIA part of an EIA provides important information in assisting and identifying the potential visual impact of a development proposal. Ideally, an LVIA will be undertaken by our landscape architects team, at the early stages of any large planning application. In a Special Landscape Area (SLA), National Park, or in an Area of Outstanding Natural Beauty (AONB) the use of LVIA enables planners to assess the likely impacts of a planning application. It also enables planners to find the best fit for your development in the landscape. There is a set methodology which Landvision are familiar with and which will be followed according to our Professional training, with our extensive experience and to the Good Practice Guidelines of The Landscape Institute.
