What's Developing in Frederick

There are all kinds of development happening today in Frederick and this monthly article will profile at least one new project so you can stay up to date on how your community is growing!


The Why and How of Roadway Classification


The Engineering Department is once again taking over What’s Developing to give residents an overview of road classification, from residential to arterial roadways.

Roads within Frederick go from smallest to the largest and the size of road is based on the amount of traffic on them or future proposed traffic. The smallest roads are the residential road that homes front to. These types of roads have the least amount of traffic on them. The next largest is a collector which are the roads that people take to leave a development. A collector will have more traffic than a residential road because more people travel the road to leave a development than the residents on a residential road do. Homes do not typically front onto this type of road because of the amount of traffic expected on that road. The next largest is an arterial. Frederick has two standards for arterials, minor and major. Arterials are the roads that you take to get around Town and to the interstate and highways. The arterials are main thoroughfares of the Town. Major arterials as classified by the Town are the arterials that parallel I-25: Aggregate Blvd and Silver Birch Blvd, the main road within Frederick that directs traffic to the main areas of commercial business and Downtown: Colorado Blvd, and the only road within Frederick that crosses under I-25: Bella Rosa Parkway. I-25 and highways 52 and 119 are the largest road types that run through or border Frederick. These types of roads are maintained by the Colorado Department of Transportation (CDOT). Interstates and highways are main thoroughfares of the state. 

A roadway network is like a network of water from a source like the snow on the mountains to a sea. The mountain snow is the traffic leaving residential and commercial areas, the tributary is the collector road that all vehicles use to exit a development, the river is the arterials that collect traffic from the collectors, and the sea is the interstate or highway where the largest number of vehicles goes. 

Arterial roads are generally where gravel county roads used to be. County roads are typically located along section lines which were created by the Public Land Survey System (PLSS). The PLSS, originally proposed by Thomas Jefferson, is used to subdivide and describe land within the United States. The grid-based system is used to break land in to blocks of standard sizes. Section lines create 1-mile square blocks with an area of 640 acres. In areas that have been surveyed by the PLSS, like the Town of Frederick Planning Boundary, most land boundaries are formed by the PLSS. With the sections lines creating boundaries between different property owners, most county roads are along the section lines. 

Since the amount of traffic on the types of roads differs, the amount of funds allocated to improve and maintain the roads also differs. Residential roads have less traffic and wear more slowly, so less maintenance is done on them versus a collector or arterial. Snow plowing is done in order from most to least traveled as well. CDOT’s snow plows can be seen on highways and interstates very close to the time that it was estimated to snow because they need to plow the roads quickly since there many more vehicles that travel those roads versus a collector or arterial. Within the Town, the arterials are plowed first and when possible, the collectors are plowed next. 

Some roads within Town do not meet the Town’s roadway standards and may be called a modified road classification. An example of that kind of road is Tipple Parkway. Since the road cannot be widened to the ultimate width of a minor arterial the road is classified as a modified arterial. This allows the Town to maintain the arterial classification since it is an often-traveled road but modify the roadway width to fit within the limited land dedicated for the road. The current layout of the lane striping and the parking along Tipple Parkway is not the ultimate design and may be changed as needed in the future to provide additional lanes for turning traffic.
