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
►The more comments and people involved the better the quality of the product.
►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.

Basic Principals
►Roadway cross-sections should be based on elements rather than one size fits all.
►Cross-section elements should be representative of adjacent land use and roadway classification.
►All current Federal and State requirements had to be included.
►Individuality of jurisdictions should be maintained.
Types of Roadway Elements
►Lane widths►Shoulder widths►Sidewalk widths►Planting strips►Bicycle facilities
Classification & Land Use

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
