No person shall open any hydrant of the water system of the Town without permission previously obtained from the Director of Public Works; provided, however, that nothing in this section shall be construed to prohibit the use of hydrants and water by the Chief of the Fire Department, or the person acting in his stead, in case of fire.
A. 
No person, except those authorized by the Director of Public Works or the North Andover Fire Chief, shall obstruct the access to or impede the operation of or alter the appearance of any hydrant of the water system of the Town.
B. 
No planting or structure shall be maintained for a distance of a ten-foot radius from the top of the hydrant.
Any obstruction or alteration shall be corrected to comply with the bylaw. Any costs incurred for correction shall become the burden of the person responsible for such obstruction or alteration and shall, if unpaid, become a lien upon that person's property.
