Arapahoe County weighs higher parkland standards, dual valuation and 2% commercial assessment

Arapahoe County commissioners on Monday reviewed a consultant report recommending an update to the county—land-dedication and cash-in-lieu policy that would raise the county—parkland level of service and revise how per-acre cash payments are calculated.

Consultant Colin McEweedy of Tischler Bice summarized the study and said the county currently collects about 6 acres of parkland per 1,000 residents. He said the study——identifies a technical ceiling of up to 18 acres per 1,000 in parts of the western county and about 16 acres per 1,000 in eastern areas, while the national average is roughly 10 acres per 1,000. "Going from 6 acres to 16 or 18 acres would be a 200% increase and, in one way to describe that, would be a shock to the development system," McEweedy said.

Why it matters: the county——has not substantively updated the policy in decades, and current assumed per-acre dollar values date from about 1990 and are far below present market rates. Staff and the consultant presented two valuation approaches: retain a static "assumed" per-acre value for predictability or continue allowing an appraisal-based approach; the recommendation to the board was to preserve a combined approach: raise assumed values to more realistic levels while keeping the appraisal option for accuracy.

How the math plays out: the consultant gave a hypothetical 100-unit western subdivision at a $200,000-per-acre land value. Under updated assumptions that scenario would require roughly 10 acres of dedication, equal to about $2 million in land value (about $20,000 per home). Under the county's older assumed values, those amounts would be much lower; the consultant cited examples of appraisal results in western parts of the county ranging from about $200,000 to $700,000 per acre, and assessor-derived undeveloped-residential medians of roughly $130,000 per acre in the west and about $40,000 per acre in the east.

Commercial assessment: staff proposed exploring a 2% commercial land assessment to spread facility costs to nonresidential development. The consultant said the 2% figure was a conservative comparator based on neighboring counties rather than a rate derived from a single stakeholder.

Board response and direction: commissioners expressed concern that adopting the 18-acre ceiling immediately would unduly shock developers and housing projects. Several commissioners, including Jeff Baker, voiced support for phasing the increases and for a more defensible near-term target at or near the national average of 10 acres per 1,000 residents. Commissioners asked staff to: (1) update the assumed per-acre values to reflect current markets while preserving an appraisal pathway; (2) examine and clarify credits for private parks and how multifamily developments are treated; (3) socialize the 2% commercial concept with economic-development and commercial stakeholders; and (4) bring the policy back on a regular cadence (the consultant and staff recommended reviewing updates every two years).

Next steps: staff said they will complete a technical report with the underlying data, do further outreach to commercial developers and other stakeholders, draft redlined code amendments to the land-development standards, and return to the board with proposed ordinance/regulation language and implementation timing (staff mentioned mid-summer as a target and discussed possible phase-in dates to avoid catching applicants mid-development season). The board did not take formal votes during this session.
