A change could be in the works for the maximum height of a front yard fence in Towamencin. It's currently three feet except for corner lots. The proposed ordinance would make it four feet except for houses that stand at an intersection. The proposal would also require the fence to have two-and-a-half times more see through space than closed area. Township officials say a split rail or a three rail fence would satisfy that requirement. The township supervisors could take action on the proposed ordinance next month.
