Shade trees that obscure light and air are illegal
You could face a stiff penalty if you own a tree by the street and it obscures the light and air.
171-2. Shade trees. The streets of the township shall be used for the purpose of public travel only, with such other use of the same as is necessarily connected with public travel. Shade trees may be planted along the streets, highways, and alleys, but not within the prescribed limits of the same. Such trees shall be planted so as not to obscure light and air and shall not be so close as to interfere with the lawful use of such streets, highways and alleys. They shall be properly trimmed by the owners of adjoining premises. No person shall wantonly or negligently cut or destroy any such shade trees without the consent of the owner of the adjoining premises and of the Committee and occupants.
