Purpose of Joint Standards

►Policy makers consider this one of their priorities.

►Recognition of developer and contractor confusion over different standards in different jurisdictions.

►Possible cost reduction for developers and contractors.

►Each jurisdiction's standards needed updating and it was more efficient to work together.

Why we’re here

►No one can think of everything so please review with your experience and the good of the community in mind.

►Written responses will be provided to those submitting comments.

Roadway Structural Sections

► The structural sections listed for each type of roadway are the minimums required and apply to the gravel and sand classifications of the underlying soils.

► The underlying silts and clays will generally require engineering analysis for a proper structural section.

► As an alternative to an engineering analysis for silts and clays, a structural fabric may be placed on top of the subgrade, under the crushed rock, as approved by the agency.

► The structural sections may be increased if a higher percentage of truck traffic is anticipated.

Bicycle and Pedestrian Facilities

►Types Bike Lanes Widen Curb Lanes Multi-Use Paths

►Placement, use, and type determined by jurisdiction
