Site Access Site-related issues address items ranging from Parking Signage Markings Accessible routes Path of travel
Learn how to design according to latest code and
ANSI standards, how to maneuver through local interpretations and gain clarifications from the state when necessary.

Site Access: NCBC 1104.1+2 Consider:
– What is the land contour? – Are sidewalks present? – Is there pedestrian traffic? – Are bus stops planned?
Vehicular access only is acceptable for: – areas with no sidewalks – areas lacking “substantial”
pedestrian traffic – areas where access is
infeasible

ANSI 406 Curb Ramps
CURB RAMP - A short ramp cutting through a curb or built up to it
CURB CUT - A ramp of short horizontal projection that is cut through a curb
![Page 14: Site Access and All Things Accessible](https://reader033.vdocument.in/reader033/viewer/2022051711/5868c06a1a28ab136b8b57c4/html5/thumbnails/14.jpg)
Without a curb cut, there is no access
![Page 15: Site Access and All Things Accessible](https://reader033.vdocument.in/reader033/viewer/2022051711/5868c06a1a28ab136b8b57c4/html5/thumbnails/15.jpg)
ANSI 406.6 does not allow this
Need to lengthen parking space in order to use a curb ramp
![Page 16: Site Access and All Things Accessible](https://reader033.vdocument.in/reader033/viewer/2022051711/5868c06a1a28ab136b8b57c4/html5/thumbnails/16.jpg)

Ramp is over 1:20 + requires handrails
Breaking it into 72” long runs with maximum 6” rise would eliminate the handrail requirement.

• Walk: measured edge to edge • Ramp: measured between handrails • Includes turning space around an
obstruction

Interpretations: AHJ + State Local AHJ
– Document your assumptions – Provide 30”x 48” wheelchair space to clarify – Indicate NCBC + ANSI code references
State
– Provide documentation from DOI pre-submittal – Where differences in opinion, suggest checking
with DOI for another interpretation – Blame client if concern with ‘offending’ AHJ
