Who pays to repair roadside grass verge

Currently waiting for a response from Wirral Metropolitan Borough Council, they should respond promptly and normally no later than (details).

Dear Wirral Metropolitan Borough Council,

Please inform me as to why, the house owner who has just built the house on the corner of Mill Lane & the A41 in Spital or the builder of said house Mark Taylor construction has not been charged to repair the damage to grass verge in the area. We as tax payers pay for the upkeep of the grass verge which are now destroyed and very unsightly

Yours faithfully,

A concerned tax payer
