4.1 General

The Colorado Department of Transportation (CDOT) has classified all roads within Pueblo County in conformance with Highway Functional Classification Concepts, Criteria and Procedure by the United States Department of Transportation, Federal Highway Administration. Pueblo County believes it to be in the best interest of the public at large for Pueblo County’s functional classification system and classification of each road to be as consistent as possible with the CDOT classification system. To better define and establish certain design requirements (right-of-way width, roadway width, etc.) the local road system classification has been sub-classified as Local Access, Local Minor Residential, Local Industrial, and Local Commercial.

4.2 Pueblo County Roadway Classification Study

Pueblo County has adopted the Pueblo County Roadway Functional Classification Study and Pueblo County Roadway Functional Classification Map. The Study and Map are periodically revised and updated.

4.3 Functional Classifications

There are nine road classifications based upon the type and level of service for which the roads are intended. Table 1 in Appendix 2 lists the key design requirements for each of the classifications, and typical cross sections are found in Figures 1 through 9 in Appendix 1.

4.4 Urban and Rural Designations

For the purposes of these standards and specifically for determining the appropriate cross-section to be used for a specific road the term urban--and therefore the urban cross-section--shall apply for any road or subdivision where one or more of the following is true:

1. The site lies within an area covered by an approved master drainage plan adopted into the Pueblo Regional Comprehensive Development Plan, and said master drainage plan recommends curb and gutter and/or storm sewer for the road or site in question.

2. The site or road in question carries any of the following zone designations per the Pueblo County Zoning Resolution: residential zones R-1 through R-8 (not including R-A), neighborhood office zone 0-1, business zones B-1 through B-4, industrial zones I-1 through I-4.

3. Predominate design grades for the road or roads in question are 1 percent or less.

4. A roadside drainage ditch adequate to accommodate the 25 year storm event (with maximum 3:1 side slopes and conforming to all other applicable County standards) would be too large to fit within the available road right-of-way without decreasing the width of the roadway itself from the minimum standard.

5. Prevailing character of the surrounding area is consistent with an urban setting--roads are constructed in general conformance with the urban cross-section.

6. The combination of drainage control, access control, pedestrian protection and other factors specific to the site are such that the Board of County Commissioners deems curb and gutter and sidewalk to be in the best interest of the public health, safety, and welfare.
