This is an addendum to the earnest money contract between the parties concerning a particular piece of property described in the addendum. The addendum states that the real property described in and subject to the contract adjoins and shares a common boundary with the tidally influenced submerged lands of the state. The boundary is subject to change and can be determined accurately only by a survey on the ground made by a licensed state land surveyor in accordance with the original grant from the sovereign. The addendum also mentions that state law prohibits the use, encumbrance, construction, or placing of any structure in, on, or over state-owned submerged lands below the applicable tide line, without proper permission.
