Park Trust urges citywide push to close Denver’s parkland gap and protect the South Platte corridor

Denver Park Trust representatives told the South Platte River Committee on Jan. 14 that the city faces a significant parkland shortfall and urged a coordinated approach to conserve and add green space — particularly along the South Platte corridor.

Rocky Pero, a retired planning director and presenter for the Park Trust, said a Game Plan analysis and follow‑up work identified about a 1,300‑acre deficit under a 13 acres per 1,000 residents benchmark; if the city maintains current patterns, Pero said the cumulative deficit could grow to roughly 3,800 acres in future decades. "Game Plan identified a gap right now of 1,300 acres in the city," he said.

Frank Rowe, cofounder and executive director of the Denver Park Trust, said the organization’s mission is "to add parks where none exist," and recommended demonstration projects and district‑level efforts to close walk‑and‑roll gaps. The presenters outlined a methodology that catalogued designated, partially designated and undesignated parkland using city parks department data and applied the 13‑acres‑per‑1,000 metric to produce district‑level gaps.

They also flagged river‑corridor problems: degraded embankment vegetation, clustering of incompatible land uses, and water‑quality concerns. The presenters cited a 2021 E. coli reading they reported at "about 137 times the federal safety standard" in portions of the corridor as evidence of water‑quality challenges that warrant coordinated remediation and land‑use planning.

Recommended responses included an overlay or a new river‑centric district, targeted buildable‑lands analyses, pilot demonstration projects such as Riverfront Park and Sun Valley, and partnerships with universities and community groups (the River Sisters, University of Denver, CU Denver and Green Latinos) to research models and help secure grants. The presenters said they had begun mapping opportunities and urged conservative, community‑led processes for acquisition and design.

Council members asked for clarifications about whether privately owned open space (metro district parks, Ball Arena open space, and designated private parcels) had been counted; presenters said the core analysis focused on city‑owned land but that some metro district and designated private parcels were included where agreements exist, and that they could refine counts for specific districts. Members also asked about counting passive versus active parkland and whether school grounds were factored in; the presenters said passive space was included and that school properties are counted when formal agreements designate them as parkland.

Councilmembers discussed policy levers — from updating set‑aside rules for large developments to exploring time‑bound legislative targets to reach national benchmark levels — and emphasized anti‑displacement or "retention" strategies when new parks are created. Presenters committed to follow‑up work: district‑level inventories and further collaboration with council offices and university partners.

The committee closed with direction for staff and the Park Trust to provide additional district‑specific analyses and to explore options for overlays or district strategies that are sensitive to neighborhood context.
