Nuisance parking blocks access to 40 Bromhedge

We request a post to prevent parking blocking our driveway. We note you have provided this elsewhere in Bromhedge (see third pic). For a year or more, cars park in an undesignated spot on the pavement by our hedge preventing us from safely accessing our drive. As we can't use the ramp, we have to manoeuvre around the cars and climb on to the pavement in order to access the drive. This is causing tyre damage but the daily distress is worse. I have asked the drivers not to block the drive but there is always a new one. Please reply urgently. Thank you.
