19.3.4 Linear Pedestrian Facility Design Criteria

Table 19-1

shows design criteria for linear pedestrian facilities. These design values may be adjusted based on the performance based practical design evaluation as discussed in

Chapter 2

. The previous and subsequent subsections in this chapter provide detailed discussions for each design element and factors that can influence these values.

**Table 19-1 Design Values for Linear Pedestrian Facilities**
Design Element		Minimum or Maximum	Desirable	Reference
Pedestrian Access Route (PAR) (e.g. Sidewalk)	Clear Width1	5-ft	6-ft to 8-ft	See 19.2.2.2 and 19.3.2.1
	Buffer Zone Width (Curbed Roadways)	4-ft from FOC	6-ft or more from FOC	See 19.3.2.2.1
	Buffer Zone Width (Uncurbed Roadways)	10-ft from Edge of Pavement	Desirable Clear Zone Width	See 19.3.2.2.2
	Frontage Zone Width (Curbed Roadways)	0-ft	1-ft or more	See 19.3.2.3.1
	Frontage Zone Width (Uncurbed Roadways)	See 19.3.2.3.2
	Maximum Cross Slope	2%	1.5%	See 19.2.2.4.4
	Maximum Pedestrian Crossing Cross Slope at Intersections	5%	2% or less	See 19.2.2.4.3 and 19.6
	Maximum Longitudinal Grade (Adjacent to Roadway / Curb)	Must not exceed general grade of the roadway		See 19.2.2.4.3
	Maximum Longitudinal Grade (Independent Alignment)	5%		See 19.2.2.4.3
	Obstacles and Protruding Objects	See 19.2.2.3
Shared Use Path (SUP)	See 18.3 and 18.4.1
Note	1. The clear width of a PAR may be reduced to 4-ft minimum for short distances, including across driveways, but passing spaces must be provided at intervals of 200-ft maximum. Passing spaces must be 5-ft minimum by 5-ft minimum. A design variance will be required if this criteria is not met.
