Rushmoor Council has secured agreement from Esso that it will submit further details for approval of how it plans to carry out trenching work close to the fairy tree and another veteran tree in Queen Elizabeth Park, Farnborough, as part of its pipeline project.
The agreement follows a request from Esso for the council to discharge some requirements in the Development Consent Order.
The council has worked with the Friends of Queens Elizabeth Park with a view to minimising the potential impacts of the work.
A small change in the route of the pipeline was necessary after the discovery of concrete blocks linked to a sewage pipe already running through the park, meaning that the trenching has to be carried out closer to a small number of mature trees, including the fairy tree.
Initial vegetation clearance is expected to start later this year, with the main work taking place during 2022.
