§ 8.7. ROAD SURFACING REQUIREMENTS

The following road surfacing requirements apply to the interior roads of all development, except rural land plans:

A.

The selection of road surfacing material should be based on factors including but not limited to safety; convenience; dust control; and maintenance considerations. Acceptable road surface types vary with traffic volumes and location: urban (within GMA districts) versus rural (outside GMA districts) and plains versus mountains.

B.

The minimum road surfacing requirements for various traffic volumes and locations are:

TABLE 8.7(B) MINIMUM ROAD SURFACING REQUIREMENTS

Pavement Type	Traffic Volume (ADT)	Material
Rural-Mountains	Less than 50	Native Material
Rural-Mountains	51—200	Gravel
Rural-Mountains	Greater than 200	Chip seal or pavement
Rural-Plains	Less than 200	Gravel
Rural-Plains	Greater than 200	Chip seal or pavement
Urban	All roads	Pavement

 

Native material surfaces will normally not be acceptable but may be allowed in exceptional cases when, in the opinion of the county engineer, the location, material characteristics, drainage conditions, road geometry and traffic volumes are suitable for this type of surface.

Chip seals will normally not be acceptable but may be allowed in exceptional cases when, in the opinion of the county engineer, the location, drainage conditions, road geometry and traffic volumes are suitable for this type of surface.

C.

Pavements must consist of either asphaltic concrete pavement or Portland cement concrete pavement, with base course and subbase course where required, placed on compacted subgrade.

D.

Structural design criteria for road surfaces are contained in chapter 5, structural design criteria, of the technical supplement to this code, Larimer County Road Standards.
