Need to get a parcel of land lowered

Hello, have 4 parcels of land from Jenna Fairplay in Da Boom. She created a small beach/harbour area for me there lowering a part of the land. It is bordering Smith area, Linden owned ocean there. But the border is a bit higher than water level on the Linden owned size, so there is a small borderline looking out of the water there. Looks really stupid.

Could you lower the borderline a bit?

If you have further questions, contact me or Jenna Fairplay.

Coordinates: about Smith(250,240)

I did a bit to make it look more like a bluff than a flat drop off, but unfortunately there isn't much more I can do without completely compromising Jenna's current set up.
