Where such water front is under the control of a local board, commission or other governing body created by legislative act, having power to improve or develop the water front or exercising such authority, so that a permit or license must be granted by it before any improvement or development may be commenced, plans proposed by it or submitted to it shall be filed with the board of commerce and navigation.

The board may, within ten days after the receipt by it of such plans, file notice of objections to the carrying out of the improvement or development, or to the granting of a permit or license by such local governing body. The filing of the notice shall act as a stay in the carrying out of the plans or in the granting of such permit or license until a public hearing shall have been held by the local governing body sitting jointly with the board. At the hearing the board may state its objections to the plans and recommend such changes as it may deem necessary.

The local governing body together with the board shall approve or disapprove the plans, or grant or refuse to grant the permit or license as seems necessary or desirable.
