Consider the requirements of the Local Planning Authority
It is important that a Heritage Impact Assessment is a robust document containing all the necessary information for a Local Planning Authority to understand the impact of proposals on the significance of affected heritage assets.
Failure to provide the correct level of information can lead to delays in decisions being made by the planning authority and this can have a knock-on affect for the applicant which may well cost time and money.
Understanding the implications of a proposals on the significance of a heritage asset from the start enables the applicant and the planning authority to investigate ways in which the impact on a heritage asset can be minimised and it is therefore, important that the applicant engages in this process at an early stage.
Whilst a Heritage Impact Assessment is intended to inform the Local Planning Authority on the impacts of a scheme on a particular heritage asset, it is also represents a risk assessment for the applicant who will be able to understand from the outset what heritage and archaeological risks will affect the proposed scheme and how best to manage and minimise them.
National Planning Policy Framework
In order to comply with the advice set out in Paragraph 128 of the National Planning Policy Framework (NPPF) applicants are required to provide a description of the significance of a heritage asset and/or its setting and, importantly, to provide sufficient information in the Heritage Impact Assessment for the Local Planning Authority to understand the impact of the proposals on the significance of any heritage assets affected.
