Section 3. Except as provided by section five, public shade trees shall not be cut, trimmed or removed, in whole or in part, by any person other than the tree warden or his deputy, even if he be the owner of the fee in the land on which such tree is situated, except upon a permit in writing from said tree warden, nor shall they be cut down or removed by the tree warden or his deputy or other person without a public hearing and said tree warden or his deputy shall cause a notice of the time and place of such hearing thereof, which shall identify the size, type and location of the shade tree or trees to be cut down or removed, to be posted in two or more public places in the town and upon the tree at least seven days before such hearing and published in a newspaper of general circulation in the city or town once in each of two successive weeks, the first publication to be not less than seven days before the day of the hearing or if no such local newspaper exists then in accordance with the provisions of section six of chapter four; provided, however, that when a public hearing must be held under the provisions of this section and under section fifteen C of chapter forty prior to the cutting or removal of a tree, such hearings shall be consolidated into a single public hearing before the tree warden and the planning board, or if there is no planning board, the selectmen of a town or the city council of a city, and notice of such consolidated public hearing shall be given by the tree warden or his deputy as provided herein. Any person injured in his property by the action of the officers in charge of the public shade trees as to the trimming, cutting, removal or retention of any such tree, or as to the amount awarded to him for the same, may recover the damages, if any, which he has sustained, from the town under chapter seventy-nine.
