The Subdivisions of Sunnyside

Sunnyside is one of Denver’s original neighborhoods, founded in 1858. Others included Berkeley Lake, Potter Highlands, Sloan’s Lake, and West Highlands. What is now Sunnyside (38th to I-70 and Federal to I-25) was, originally comprised of:

The Original Sunnyside: 38th to 41st, from Pecos to Tejon

This small development was only three blocks square, but this happy name was eventually chosen by the Planning Commission to represent the entire area from 38th to I-70 and Federal to I-25.


Lewis K Perin’s farm: 44th to 48th, Federal to Zuni

If you live in this area, you may have the same rich soil that Lewis K. Perrin used to grow his crops over 135 years ago! Perrin was one of Colorado’s earliest successful farmers, moving to NW Denver in 1875. He built a large house (since demolished in 1958) at what would now be 4375 Clay Street. He grew sugar beets, and there was an orchard, a grape arbor and a deep 850-foot well that piped water to neighbors as far away as 41st and Alcott. He planted the long windbreak of cottonwoods along 44th, which stood until the street was widened in 1927. Lewis Perin died in 1897.


Perrin’s Addition: 38th to 44th, Federal to Zuni

While Perin’s actual farm was comprised of one piece of land, this area was broken up into smaller blocks, and the farmland was subdivided into plots for strawberries raspberries, asparagus and celery.


North Highlands: 44th to 48th, Zuni to Pecos

With original streets named for wildlife (Antelope, Bison, Coyote Deer and Elk) North Highlands was comprised of small Victorian houses, scattered with newer homes as the years went on.


The Village of Argo – 44th to 48th, Pecos to Broadway

The Village of Argo (including Richardson’s subdivision) – incorporated in 1879 – was built around the Boston and Colorado Smelting Company, founded by Nathaniel P. Hill. Hill developed a process of extracting gold from ore. The smelter burned in 1913 and was never rebuilt. A major public housing facility opened in 1952, but a few small original Argo houses can still be seen in this area.

Richard’s Subdivision was laid out in blocks, and served as an area for company workers which was complete with a hotel, small shops, a Methodist church, an elementary school, train stop and horse car line which traveled up Pecos to 38th, and then Lipan to 44th. Later, trainmen employed by the Moffet railroad also lived in Argo. Almost all the residents were immigrant families – Swedish, Germans, Scottish, Hungarians. In 1902, Denver was made into a separate county and the village of Argo was swallowed up.


Unincorporated Areas:
Several areas of Sunnyside were unincorporated while these larger plots were divided up. They may have been farmland or just prairie.


Trolleys in Sunnyside

In 1871, horse-drawn streetcars began service in Denver, and in the 1888 Denver Tramway Company began cable car service. In 1901 the Tramway Power facility opens – where REI is now located.


In 1896 Horse cars ran down Pecos St. into downtown, as well as out to the Village of Argo The trip from North Denver into downtown via horse car was reported to take about an hour.


By 1905, a number of street car routes were present throughout the Highlands neighborhood. No location in the neighborhood was more than three blocks from one of the trolley routes. Trolley Line #28 Traveled North up Tejon, down 44th, and ended at the Shrine Temple at the Case Golf Course. Trolley Line #13 Traveled down Clay, up 38th and continued on to Elitch Gardens.


Several of the business and retail areas of our neighborhoods off major feeder roads (Tejon, 44th Avenue) make a lot of sense when you envision the trolley lines that extended past them. In fact, many of these same lines are used by buses today.


In 1950 Streetcar service ended, although there have been several proposals by Cable Car enthusiasts to bring them back.
