Standard Details

Standard Details are provided for constructing various Clark County projects. Details include roadway, drainage, sidewalk and development.

Example of Standard Detail for Combined Curb Ramp.

Standard Details have been grouped according to specific construction categories.

Clark County's Public Works Director has approved and signed each Standard Detail. As standards change, each detail is updated on an "as needed" basis, with the Public Works Director approving and signing all changes.

The revision date is included on all Standard Details. Clark County Public Works is working to develop a list with each detail and its revision date and expects to add that to this webpage later in 2017.

Standard Details are not to be modified from their current form. Any modification requires removing all signatures since Clark County has not approved the change. Anyone making modifications must assume full responsibility for the changes made.
