The Ballpark district, named for its proximity to Coors Field, is becoming a hot residential neighborhood adjacent to Downtown Denver.  The area is primarily industrial in nature, consisting of a mix of historic 19th century brick warehouses and generally unremarkable industrial structures from the mid 20th century.  Many of the historic buildings have been or are being renovated and converted into residential and retail uses.  Now, new construction is starting to fill in the undeveloped lots or replace the non-historic industrial buildings in the district.

The district will also benefit from a planned transit station in the vicinity of 35th and Downing, as part of the extension of the Central Corridor line under the FasTracks transit program, as well as the transit station at 40th Street/40th Avenue where the Central Corridor line and the East Corridor commuter rail line to Denver International Airport will connect.

The adjacent Arapahoe Square district is certainly the most underdeveloped part of Downtown Denver. Deteriorating buildings and parking lots dominate. With much of the area cleared in the 1970s and 1980s to serve as a parking reservoir for daytime office workers, Arapahoe Square has never recovered. But, as development pressures mount and available land throughout Downtown continues to become more sparse, Arapahoe Square has recently gained the attention of the development community.

Proximity to the core Central Business District and access to light rail gives Arapahoe Square great redevelopment advantages. The 2007 Downtown Area Plan calls for the evolution of Arapahoe Square into a mixed-use residential district featuring mid-rise structures, public spaces, ground-floor retail, and pedestrian-oriented streets–essentially everything that Arapahoe Square currently lacks. Much work remains to be done, but Arapahoe Square represents a huge growth opportunity for Downtown residential over the next several decades.
