Following a few queries about the length of the grass to the verges, I spoke to the contracts team at EHDC who organise this.
The verges have 9 cuts per year. These are between early March and late October at approximately monthly intervals. When it is wet the schedule does slip a bit which can also result in the grass getting a bit longer than we would like. Please do not park on the verges as this makes it difficult to keep our community tidy.
