What is a Road Modification?
A Road Modification is a variance to county transportation standards. Clark County Code (CCC) 40.550 specifies their classification of modifications, typical examples, and approval criteria.
Are there different types of Road Modifications?
Yes. There are three types of Road Modifications depending on the complexity of the request.
Minor Deviations: Common minor variations that have minimal, if any impacts. See Clark County Code 40.550.010B(1).
Technical Road Modification: Minor changes to the standards related to access, safety, cross sections, or construction materials. These variances have greater impacts onsite or offsite so require more documentation and analysis. See Clark County Code 40.550.010B(2).
Major Road Modification: Requests with the potential of significant impacts to the public and county. These tend to be unique requiring more extensive documentation and analysis. Examples include the addition or elimination of medians, cross circulation changes, and design changes concerning traffic or pedestrian safety. See Clark County Code 40.550.010B(3).
Is a Pre-Application Conference required?
No. A pre-application conference is not required for a Road Modification request.
Is a professional engineer required to stamp the application?
Minor deviations do not require preparation by a professional engineer. Technical and Major road modifications must be stamped by a professional engineer licensed in Washington.
