Sec. 3-3. - Sight triangles for traffic visibility.

Except as permitted herein, in any zone, at any street intersection, railroad crossing, or any driveway intersection, no fence, structure or planting, other than ground cover, shall be erected or installed within the sight distance triangle as shown in the table and the illustrations below.

MAJOR APPROACH

SIGHT TRIANGLES AT INTERSECTIONS1, 2, 3

MINOR APPROACH

		PUBLIC OR PRIVATE STREET	DRIVEWAY
MAJOR APPROACH	Major Arterial	L = 325 feet	L = 325 feet
		R = 150 feet	R = 150 feet
		M = 15 feet	M = 15 feet
	Minor Arterial	L = 325 feet	L = 275 feet
		R = 150 feet	R = 150 feet
		M = 15 feet	M = 15 feet
	Collector	L = 200 feet	Nonresidential
		R = 150 feet	L = 200 feet
		M = 15 feet	R = 150 feet
			M = 15 feet
			Residential
			L = 150 feet
			R = 120 feet
			M = 15 feet
	Local Street	L = 175 feet	L = 75 feet
		R = 130 feet	R = 55 feet
		M = 15 feet	M = 10 feet

 

UNOBSTRUCTED SIGHT TRIANGLE

SIGHT TRIANGLES AT RAILROAD CROSSINGS1, 2, 3

APPROACH

 

	PRIVATE OR PUBLIC STREET OR HIGHWAY	ANY TYPE OF PRIVATE DRIVEWAY
Railroad Approach	D = 725' M = 35' or 9 feet behind stop bar, whichever is greater L = 8'	D = 325' M = 25' L = 6'
Where D' =	Distance along rail	Distance along rail
Where M' =	Distance from rail/stop bar	Distance from rail
Where L' =	Distance from edge of pavement	Distance from edge of pavement

 

1 The table assumes right angle intersections and straight major approach movements within the sight distance. Situations involving skewed intersections, curvilinear streets and other mitigating factors shall have sight distances, as determined by the Urban County Traffic Engineer.

2 In the B-2, B-2A, and B-2B zones, the sight triangle may be modified at signalized intersections, as determined by the Urban County Traffic Engineer.

3 Wire or chain link fences may be located within the sight triangle when approved by the Division of Traffic Engineering and the Division of Building Inspection upon a finding that visibility would not be impaired.
