The department may prepare plans for, and acquire, construct, develop, and improve, small craft harbors, facilities in connection with the harbors, and connecting waterways. A small craft harbor so acquired or developed may be transferred, and its operation relinquished, to a county or city, or a district having power to operate a small craft harbor, in which any part of it is located, upon the request of the city, county, or district, if the city, county, or district enters into an agreement with the department for repayment to the state of all costs incurred by the department in acquiring and developing the small craft harbor, including planning costs. The city, county, or district shall be required by the department to repay those costs. The payments shall be made in the amounts and at the times that are provided by the agreement.
