Alternative site assessment ASA

Contents

[edit] Introduction

An Environmental Impact Assessment (EIA) ensures that the environmental effects of a proposed development are properly considered. For more information see: Environmental Impact Assessment. It provides the local planning authority with better information about certain types of projects, enabling them to make a more informed decision about whether permission should be granted and to allow imposition of more appropriate conditions and obligations to mitigate possible negative impacts.

It will typically include assessment of appropriate alternatives, including an alternative site assessment (ASA).

[edit] Purpose

The purpose of an ASA is to explore whether or not the site proposed for a development is the most suitable one, or whether alternative sites could be preferable.

Due to the impact they may have on the outcome of the planning process, it is important to have ASAs undertaken during the very early stages of a project - not as a process of post-rationalisation after a site has already been selected, and very early appraisals of potential sites may be carried out by a surveyor before the appointment of the consultant team during the business justification stage.

[edit] ASA guidance

There is no formally prescribed process or methodology for undertaking an ASA. The process should be adapted to the characteristics of different projects. However, the Surrey County Council offers suggested stages of an ASA, including:
