Introduction to identifying, assessing and selecting sites

Draft guidance on identifying, assessing and selecting sites for development as part of the local plan making process.

Applies to England

We will review this guidance and make any necessary revisions and updates as the new system is implemented and related policy is confirmed.

For plans under the legacy plan-making system

If you aresubmittingyour plan under the legacy system, use thecreate or update a local plan legacy system guidance.

The legacy system covers plans to be adopted under thePlanning and Compulsory Purchase Act 2004, excluding the amendments made by the LURA,and The Town and Country Planning (Local Planning) (England) Regulations 2012.

This guidancesets out a recommendedprocess to follow whenidentifying,assessingand selecting sitesfor local plans.We recommend that you read the whole guidance before you start.

About the sites process

The sites processallows you toidentifyand assessland that could be used for housing or employment,as well as other land uses, and select which sites to put forward in your draft plan.

It’san essential part of preparingyour local planand delivering a spatial strategy.Comprehensive siteselectionhelps you deliver on your plan-making needs andobjectives.This guidance is designed to help you meet the expectations of national planning policy.

The 4 stages

The site selection process consists of four stages:

  1. Stage 1 – identifying sites
  2. Stage 2 – assessing sites
  3. Stage 3 – determining your draft allocations
  4. Stage 4 – confirming your draft allocations and recording your decisions

Getting started

You can begin work to understand the availability of land in your area and commence the sites process early in plan making. See the 30-month plan process overview for further guidance on timescales and preparing local plans.

Depending on your local circumstances you may want to work with neighbouring authorities to produce joint evidence on site identification and land availability.

Who this guidance is for

This guidance is primarily designed for local planning authorities (LPAs).

The method set out in this guidance is designed to support local plans. It could also be used to identify land for minerals and waste plans.

Neighbourhood planning bodiescan also use the method set out in this guidance to assesssitesbut any assessment needs to be proportionate to the nature of the plan.

Neighbourhood planning bodies may also make use of existing site assessments prepared by the LPA as a starting point whenidentifyingsites toallocatewithin a neighbourhood plan.

How to use this guidance

This guidance is designed to support the identification and assessment of sites for housing and employmentdevelopment,however you could adapt this for other land uses.

It will help show you’ve followed a robust approach to site selection. Its goal is to increase the likelihood your plan is found to be sound at examination.

Your assessment needs to be thorough but proportionate, building where possible on existing information sources outlined within the guidance.

This guidance focuses on:

  • a framework and supporting methodologies for identifying sites
  • what data to collect during the call for sites process
  • how to assess sites you have identified
  • an approach to selecting the sites that meet your plan vision
  • documenting yourdecision makingon why you selected these sites

It provides direction on siteselectionwhile still being adaptable so you can consider local needs and circumstances. No twoLPAsare the same or face the same challenges and this guidance does not seek to replace local planning judgement. Instead, it provides a consistent framework to work in.It’sflexible enough to account for local circumstances and we encourage you to adapt it to your needs.

It’simportant you documentwhen and why you make decisions on the sites you select throughout the process, particularly where you havedepartedfrom this guidance. To meet national policy expectations, you should be able to show thatyou’vefollowed a logical, consistent method toidentifyand select the sitesyou’retaking forward as draft allocations, and why youhaven’ttaken forward alternatives. You can find more information on recording your decisions in Stage 4.

Other requirements to consider as you go through the process

There are other legal requirements, which are not set out in detail in this guidance, to bear in mind as you go through the sites process.

The Environmental Assessment of Plans and Programmes Regulations 2004 (Strategic Environmental Assessment (SEA) Regulations) applies to qualifying plans and programmes. If the SEA Regulations apply to your local plan, they broadly require that you:

  • assess the likely significant environmental effects of your local plan and reasonable alternatives to that local plan
  • consult on an environmental report containing that assessment
  • when adopting the plan, explain how the SEA process influenced the plan

To help meet SEA requirements through your sites process, you should consider and keep records of:

  • the likely significant environmental effects of your spatial strategy and preferred site selection
  • alternatives to your spatial strategy and preferred sites that meet your policy objectives, and the likely significant environmental effects of those alternatives
  • how you have used the information you recorded to inform your preferred spatial strategy and site selection

Following the method set out in this guidance will help you meet SEA requirements related to consideration of sites.

More guidance on SEA will be published in future.

In accordance with , you may be required to carry out an assessment if your plan is likely to have a significant effect on a protected site.
