Electric meters located on the front 1/4th of the house may not be fenced in.

Fences shall not interfere with the public safety, and shall not interfere with the safe movement of motor vehicles, bicycles, or pedestrians. In order to preserve sight distance an unobstructed view shall be maintained within the triangular sight distance area on your property.
The triangular sight distance area is measured as follows:
- At the intersection of two streets, or where a street intersects an alley: a triangle defined by measuring thirty feet in length along each curb or edge of roadway from their point of intersection, the third side being a diagonal line connecting the first two.
- At the intersection of the street and a driveway: a triangle defined by measuring fifteen feet in length along the edge of the driveway and along each curb or edge of roadway from their point of intersection, the third side being a diagonal line connecting the first two.
