Hartman platted the land in squares as opposed to rectangles, which created a group of streets with slight variation from other sections of the neighborhood.

[7] Von Winkler purchased a thirty-two block site directly north of Hartman's Addition, just east of City Park,[2] for $20,000.

[9] This led to blockbusting practices by realtors to increase housing sales, and the integration resulted in white flight.

[10] In recent decades, the Park Hill community has been active on various quality-of-life issues, such as toxic waste, airport flight paths, and crime.

[14] In recent years, a significant number of black residents have left Northeast Park Hill as housing in the area has become more expensive.

Sitting on the former Ezra M. Bell estate, it was the first desegregated junior high school in Denver as per the Keyes v. DPS case in 1969.

Smiley Campus is a Tudor Revival school with various shades of red brick, contrasting buff-colored cement, and light terra-cotta ornamentation.

[16] The Denver Public Library branch on Montview Boulevard is a Carnegie Foundation-funded building that mirrors the ornate residential designs of the street.

Designed by Denver architect brothers Merrill and Burnham Hoyt, the library features a Mediterranean-inspired exterior with cast stone cornice, trim, and decorations, red Spanish roof tiles, coffered eaves, and wrought-iron entry lamps.

The interior space consists of a single large room with leaded, diamond pane windows, wrought-iron and glass globe reading lamps, built-in bookcases and window-bay seating, textured walls, a beamed ceiling, and a cast stone fireplace adorned with a bas-relief ship from Coleridge's poem, The Rime of the Ancient Mariner, by Denver sculptor Robert Garrison.

Relocating to its current location at 1501 Albion Street in 1902, the facility has grown into a fifty-room complex that includes a playground.

The course hosted various charity tournaments and a Park Hill Invitational from 1936 to 1957 that featured celebrities like Bing Crosby, Joe Louis, Bob Hope, President Dwight Eisenhower, and Arnold Palmer.

[17] In 1986, the Clayton Foundation, which managed the trust that owned the course, put the property on the market but was unable to sell the land, likely due to the oil and gas bust of the 1980s.

Instead, in 1997, Mayor Wellington Webb made a deal with the foundation to place a conservation easement on the land to limit its use to a golf course and open space.

[17] In 2019, Westside Investment Partners purchased the land for $24 million, taking over a lawsuit filed by previous leaseholder Arcis Golf against the city of Denver.

The GPHC, managed and staffed largely by volunteers: serves as a liaison between local residents and businesses and the City and County of Denver; publishes a monthly newspaper, the Greater Park Hill News, which is distributed free to residents of Park Hill's administrative neighborhoods and nearby businesses; operates a Youth Jobs Program to help young people ages 12–15 find summer jobs; and sponsors an annual home tour in the fall, The Greater Park Hill Home Tour, which has been held for the past 30 years.

[21] In 2021, journalist Julian Rubinstein released a book titled, "The Holly: Five Bullets, One Gun, and the Struggle to Save an American Neighborhood."

The book follows Roberts' trial for attempted murder, assault, and possessing a weapon, while highlighting the psychological toll of his experiences.

Rubinstein's work emphasizes the complexity of addressing violence, as it is influenced by state surveillance, structural racism, and socioeconomic struggles.

In late 2005, DURA announced it would work exclusively with Alliance Development Partners, Inc., to redevelop the site when remediation was complete.
