Information for landowners
Before we submit our application for development consent, we are undertaking work to understand who has a legal interest in the land in and around the areas considered as part of North Humber to High Marnham.
Under the Planning Act 2008, we are required to identify persons with an interest in land for the purposes of consultation and notification, a process known as ‘diligent inquiry’. We have appointed the land referencing firm, WSP, to assist with diligent inquiry by identifying and contacting individuals to confirm their interest in the land.
Surveys
As part of our application for development consent, we will submit a detailed environmental statement. Over the past few years, we have been carrying out surveys at locations along the route of the project to inform this assessment and help us to understand more about the environment around our proposals. These surveys will continue as we approach the submission of our application, which is currently planned for later in 2026.
In some cases, survey activity may continue after we have submitted our application for development consent. This is because surveys are undertaken during appropriate seasonal windows, depending on the type of survey and the species or features being assessed. Some surveys can be carried out throughout the year, while others are restricted to certain seasons to ensure accurate and reliable results. Where surveys require seasonal timing, works have taken place since 2023 and remain ongoing.
All key stakeholders, such as the local planning authorities and environmental bodies have been fully informed of our planned works. Access to land parcels is agreed before any surveys may take place between our land agents Dalcour Maclaren, landowners and any occupiers / tenants.
