I have received this note from the county council which is now managing the project.

We have given your specification to our contractors to price and give potential dates for works to commence. These should be with us just after Easter. We have been reminded that scheduling the work will need to be mindful of the nesting season (early March to late August) as even hedge pruning and clearing of vegetation can be deemed inappropriate in some instances. We will do everything we can to get the works started as soon as possible but experiences elsewhere in the borough tell us we need to take care.
