Skyline Park: Legacy, Loss & RenewalIntroduction
Brief History• Urban renewal process• Replaced “historic” D&F building• Halprin inherited the park space masterplan
by Hatami and Tanaka and Sasaki• Public process
The Plan • Response to 70’s “cities and streets are
dangerous”• Retail 100’ from street and no sidewalk• Metaphorical Rock Mountain “arroyo”• Intended as “sanctuary” from city life• Sunken from street, sightlines, and
circulation• Not an example of Halprin’s “celebration of
the city’s rambunctious vitality”

ASLA 2014 Annual Meeting and EXPO
The Park’s Decline• Quiet space fell from favor as
downtowns are revitalized• The 16th Street mall started
downtown revitalization• Retail edge failed• Sense of danger• Dependence on artificial
programming limited by inflexible spaces
The Forces of Change• At the nexus of emerging urban core
and LODO• Rising downtown political and real
estate interests• Outreach to Halprin for advice • Masterplans by Design Workshop
and Urban Strategies recommend redesign
Skyline Park: Legacy, Loss & Renewal
ASLA 2014 Annual Meeting and EXPO
Design Selection Process • National outreach• Field visits to short list firm’s
successful public spaces
“Redesign” Process• The rise of “Friends” and influence
on Design Committee• Halprin workshop• City decision to move forward• Negotiated final plan• Change called for transition from
“stage set” to “setting an urban stage”
Incomplete Vison• Missing centerpiece Denver Heritage
Fountain at corner of 16th St. Mall• Failed retail• Incomplete north block • Public art not installed on cultural
spine
