Any time new developments located in the public eye could cause significant effects on the aesthetic appearance of the surrounding landscape, a Visual Impact Assessment (VIA) would be needed to ensure that the proposed development doesn’t disrupt landscape character in the eyes of individuals in the area.
Numerous factors act as crucial considerations in the planning process, including the concept of predicting the impact of development proposals before they have even started. Although a sometimes concerning and difficult part of planning from any of the selection of development types, it is the duty of all developers to guarantee that necessary surveys on the site have been undertaken to ensure damage to the environment and local communities is identified and eliminated at all costs.
Of the potential affects caused by a proposed development project, a developer may need to take changes to the economy, flora and fauna, individual health, and society into consideration. Not only can this pose varying levels of difficulty, but also contextual interpretation that can put direct or indirect consequences of a specific project up for debate.
A troublesome feature to quantify on any site is the visual impact on the local and surrounding landscape, judging what a quality landscape looks like, and determining if a planning project has any potential negative impacts on the landscape and visual appearance of the environment. It is possible to professionally analyse the potential visual impacts on a plot of land, however, through the use of a Visual Impact Assessment conducted by a licensed land surveyor.
Also commonly referred to as a Landscape and Visual Impact Assessment (LVIA), a Visual Impact Assessment (VIA) is a survey on a development site that analyses the influence on the environment, breaking down each element of the site into separate component parts. A VIA is applicable on all minor or major developments that are expected to cause significant visual impacts on the countryside, and planning applications in a registered Area of Outstanding Natural Beauty (AONB) and recognised well-known beauty spots.
A Visual Impact Assessment – or Landscape and Visual Impact Assessment – is also required on any planning projects that could fall within the characteristics of an Environmental Statement from The Town and Country Planning (Environmental Impact Assessment) Regulations 2017. An example of this would be wind turbines, as the total height would exceed 15 metres, making it a new piece of infrastructure that the Town and Country Planning Regulations would perceive as an environmental statement, therefore capable of impeding the visual appearance of the local environment.
In simple terms, visual impacts are an aesthetic change to the landscape following the completion of proposed new developments. For a proposed change to be identified, the character, value and quality of the environment needs to be assessed before and predicted after the specific project to gauge whether a significant alteration will take place. Although it could be subjective and hard to determine whether individuals are valid claiming an impact to the surrounding landscape and visual appearance of the environment, the activity, location and nature of the landscape and project will function as the deciding factor.
As a result, context and the typical reaction of the average individual based on purpose and location play an important role in working out if visual impacts will be adversely affected. The level of sensitivity based on the reaction of individuals is typically determined as follows:
Low sensitivity – people engaged in outdoor sports, people in commercial buildings
Medium sensitivity – people using footpaths, people using road vehicles, people in upper storeys of residential properties
High sensitivity – people in principle rooms of residential properties, people visiting well-known beauty spots
Using the guidelines for landscape projects as detailed above, a land surveyor carrying out a Landscape and Visual Impact Assessment would raise concerns over high sensitivity areas, potentially question medium sensitivity areas and likely waive issues in low sensitivity areas.
When it comes to minor or major developments that could affect the local surrounding landscape and its visual appearance, local authorities may ask for assurances that there has been some level of consideration over the impact that could be caused, as well as alterations and limitations that could eliminate or reduce harm coming to the environment.
Changes to legislation that focus on the environment – such as the introduction of biodiversity net gain (BNG) within the Environment Bill 2021 – have displayed an intention for local councils to regulate planning projects and put restrictions in place until guarantees in the form of professional surveys and a level of visual impact analysis has been presented clearly to them.
If a planning project was proposed on an undeveloped plot of greenfield land in a high sensitivity area, it would be likely to raise the concerns of the planning department of the local council. An important purpose of a VIA is to demonstrate to the corresponding local planning authority that a visual assessment on the site has been conducted by a qualified surveyor, making the process of passing planning applications far simpler.
Prior to the project, the developer should first arrange a Landscape and Visual Impact Assessment (LVIA) in order for a land surveyor to look over the site and offer comprehensive insights into the nature of the project. Following completion of the visual assessment, the land surveyor will produce an extensive report formed from details about the survey, information about the development site and recommendations that will allow the project to move forward, even if there are alarming reasons that would otherwise lead the local authority to reject an application for planning permission.
Based on the information detailed at length within the VIA report and any other key documents and survey reports provided to the local planning authority, there should be no reason but to grant a planning condition on the site, allowing the proposed development to move forward with planning consent from the local authorities.
In order for the surveys and the detailed guidance from our landscape professionals to be consistent, we insist on following strict requirements from the landscape resource of a responsible body. More specifically, our VIAs follow the landscape resource of Guidelines for Landscape and Visual Impact Assessment (LVIA) from the Landscape Institute (LI).
Within the guidelines of landscape surveys are a number of important factors for how a Landscape and Visual Impact Assessment should be conducted, with one of the most crucial being that the Landscape Institute stand firm on the concept of solely qualified and experienced land surveyors undertaking assessments. Exceptions to this rule will only be made if professionals from other areas have the necessary training and expertise to conduct a Visual Impact Assessment with the same level of quality and insight.
Through universal utilisation of the Guidelines for Landscape and Visual Impact Assessment (LVIA) surveys from the Landscape Institute, our land surveyors guarantee that the same process will be followed during every site visit for a VIA.
Under certain circumstances, we may be required to alter our approach in order to meet the specific needs of our clients or survey a plot of land that isn’t necessarily standard. However, any potential proposed change to the process will only be initiated if it doesn’t harm the integrity of the visual assessment or contradict the requirements of any landscape resource we refer to.
Looking at the general process of undertaking a Visual Impact Assessment, the survey is typically split into five core steps. Below, we have detailed each of these steps to explain exactly how one of our VIAs would play out on your development site:
1. Planning and Preparation –
2. Surveying the Site –
3. Preparing Visual Simulations –
4. Analysing Visual Simulations –
5. Developing the VIA Report –
After every Landscape and Visual Impact Assessment (LVIA), the land surveyor in charge of the survey will develop a comprehensive report. In the report are sections given to the data retrieved during the assessment, findings suggested by the surveyor, and information about the general nature of visual impacts and the VIA survey.
While every stage of the visual assessment process is important, the Visual Impact Assessment report is the most crucial component as it will contain the evidence needed to satisfy significant stakeholders. First and foremost, the report can be submitted to the planning department of the local planning authority to support an application for planning permission. Based on the extensive nature of the report, there should be no reason for the local authority to deny planning consent.
A VIA report typically includes:
Depending on the site and project, a Landscape and Visual Impact Assessment report may also need digital terrain model presentation criteria, digitally retouched photographs, sight-line plots from key view points, and a more in-depth form of visual force or visual impact analysis.
The majority of proposed development projects based in public locations are likely to impede the landscape and visual effects in the eyes of nearby pedestrians, residents and travellers. Although certain significant effects on the landscape and visual impact may be completely unavoidable, it would be strongly advisable to gain guidelines for landscape planning projects, particularly if you need a survey before your local planning authority will grant planning permission.
