City of EastBorough Traffic Ordinances


Motorists in Eastborough should have a clear and unobstructed viewing area of traffic at intersections. This area is called a SIGHT TRIANGLE. By having this area clear, motorists should have enough time to see each other, react and avoid an accident.

Ordinance Requirements

Ordinance No. 1159 of the City of Eastborough is the sight obstruction ordinance. It basically states three requirements regarding objects located within the triangular area:

  1. Fences must not exceed 3 feet in height within the triangulated area.
  2. All shrubs, hedges, spreaders, etc. must not exceed 44 inches above the gutter level.
  3. All trees must be trimmed of limbs and sucker growth to a height of at least 6 feet above the gutter level.

If you have any questions about your property, the Chief of Police and his staff will help you determine if you have a sight obstruction. For more information, call 682-4111.

Uncontrolled Intersections

An uncontrolled intersection is generally in a residential area and has no signs or signals. Two of the lines that form the sides of the sight triangle are the two center lines of the intersecting streets (streets A & B in the drawing). Start at the point where the two lines intersect. Measure back along each center line 90 feet and mark a point. Then construct a line connecting the two points to form the third side of the triangle. Objects (trees, shrubs, fences, etc.) within this triangular area are subject to the ordinance requirements.

Controlled Intersections

Controlled intersections have stop signs, yield signs, or traffic signals to assign traffic right of way. Here the shape of the sight triangle varies with the speed limit on the intersecting streets. The greater the speed limit, the larger the sight distance required for a motorist to see and react to oncoming traffic. In the example, a 30 mph speed limit is used. The stop sign is located on street B, so measure 9 feet back from the curb line of street B. A motorist should be able to see 235 feet to his right and 200 feet to his left from this point 9 feet behind the curb line. Mark these respective points on street A and visually draw lines to connect these marks. Remember, this triangle will change in size with speed limit changes. Contact the Chief of Police for distance requirements other than the speed sample shown.
