(Ord. 2715 § 1, 1999)
(1) 
Sight Triangle Requirements. In all areas of the city where yards or open space are required in front yards or side yards, sight triangles shall be maintained at intersections of streets, and intersections of driveways and other entrances to streets in order that visibility may exist from one to the other, enabling operators of motor vehicles, bicycles, pedestrians, and others using such streets, driveways and sidewalks, to observe other motor vehicles, bicycles, pedestrians and others before entering streets or crossing sidewalks from other streets, or driveways.
(2) 
Intersections and Entrances.
(a) 
Driveways from Private Property Emerging on to Streets Where There Are No Sidewalks. At all locations in the city of Longview where front or side yards are required by LMC Title 19, where driveways emerge onto streets, and where, on both sides of such driveway, there are no improved sidewalks existing between the land abutting such street and the paved portion thereof, there shall be maintained a clear field of vision between a point which is 42 inches above the edge of roadway where the driveway intersect or merge, and 96 inches above such point. Such field of vision shall be of such distance as to enable the operator of any motor vehicle, bicycle or other transportation device to clearly see onto the intersecting street from a distance which is 10 feet back from the point where such driveway intersects with such street, and along the intersecting street for a distance of not less than 10 feet, providing for a clear field of visibility. Said field of vision area is described as a triangular-shaped area determined by measuring from the point where the driveway and the paved portion of the street intersect, a distance of 10 feet along the driveway and 10 feet along the nearest edge of the pavement of the street onto which such driveway emerges, in both directions.
Property which adjoins a property with a required sight distance triangle for a driveway shall be required to maintain plantings consistent with the requirements of this chapter.

Such field of vision shall be of such distance as to enable the operator of any motor vehicle, bicycle or other transportation device to clearly see onto the intersecting street from a distance which is 10 feet from the edge of the sidewalk which is nearest the property line and along the intersecting sidewalk for a distance of not less than 10 feet, providing for a clear field of vision. Said field of vision area is described as a triangular-shaped area determined by measuring from the point where the driveway and the paved portion of the sidewalk intersect, a distance of 10 feet from the edge of sidewalk, along the driveway and 10 feet along the nearest edge of the pavement of the sidewalk onto which such driveway emerges, in both directions.
Property which adjoins a property with a required sight distance triangle for a driveway shall be required to maintain plantings consistent with the requirements of this chapter.
(c) 
Streets Intersecting Other Streets. At all locations in the city of Longview where front or side yards are required by LMC Title 19, where streets intersect with other streets, there shall be maintained a clear field of vision between a point which is 42 inches above the highest level of such streets and 96 inches above such point. Such field of vision shall be of such distance as to enable the operator of any motor vehicle, bicycle or other transportation device to clearly see onto the intersecting street from a distance which is 20 feet along the property line from the point where such street rights-of-way intersect, providing for a clear field of visibility from each of said streets. Said field of vision area is described as a triangular-shaped area determined by measuring from the point where one street right-of-way intersects with another street right-of-way a distance of 20 feet along the right-of-way of one street and 20 feet along the intersecting edge of the intersecting street right-of-way.
