Central Park's newest front door has an accessible ramp, flushing toilets, drinking fountains, and a lobby that didn't exist eighteen months ago. Bluff Lake Nature Center held its grand opening celebration on February 14, drawing close to a thousand people to see the finished $8.5 million campus project, then reopened its trails for daily public access two days later. The improvements were years in motion: groundbreaking in March 2025, the building frame going up that August, a new boardwalk added to the Secondary Creek Loop Trail this past February to give the channel more room to flow.
Denver7 reported that the annual sidewalk fee assessed to Bluff Lake is $14,685.50. The 123-acre preserve has few sidewalks.
A Neighborhood Fixture, Officially
Bluff Lake sits on the eastern edge of the old Stapleton Airport footprint, along Sand Creek, and it shows up on neighborhood maps as one of Central Park's twelve named sub-areas alongside Beeler Park, Eastbridge, and Conservatory Green. It's also a listed member of the Central Park Business Association. Some accounts describe it as sitting just outside the strict Denver boundary line, since part of the site crosses into Aurora, but functionally it's been part of Central Park's daily rhythm since the nonprofit took ownership of the land from the City of Denver in 2008.
The numbers explain why it matters to so many households here. Nearly 8,000 elementary students visit each year through formal education programs, on top of homeschool programs and more than 30 scholarships that cover summer camp spots for kids who couldn't otherwise afford them. The site is open sunrise to sunset, 365 days a year, free of charge, with the only real restrictions being no bikes and no pets, even leashed, to protect the wildlife that draws people there in the first place.
Executive Director Rachel Hutchens has described the appeal in plain terms: a place to find a few minutes of quiet and reconnect with something outside the pace of the city around it. That mission is what the new campus was built to support, while the fee remains a budget consideration for the nonprofit.
Where the Bill Comes From
Denver's sidewalk fee isn't new policy confusion. Voters approved Ordinance 307, known as Denver Deserves Sidewalks, in November 2022, shifting responsibility for sidewalk construction and repair from individual property owners to the city. The fee that funds it started showing up on stormwater bills in 2025, split into two payments a year. About 96 percent of property owners in Denver pay a flat $150 annually, covering any parcel with 230 feet or less of frontage along the public right of way. Beyond that threshold, the charge adds $3.50 for every additional linear foot.
That formula is where Bluff Lake's bill turns unusual. Running the math backward from its $14,685.50 total: subtract the $150 base fee, divide the remaining $14,535.50 by $3.50 a foot, and you get almost exactly 4,153 feet of billable frontage beyond the threshold. Add the 230 feet back in, and the nature center is being charged as if it has roughly 4,383 feet of frontage along Denver's public right of way.
Denver7 Investigates checked the fee against other high-value Denver properties, including churches and commercial buildings assessed in the tens of millions of dollars, and found nothing that matched what Bluff Lake owes. Part of the reason is structural. The ordinance's own language states that the fee applies whether or not a sidewalk actually exists on the property. Because the fee is based on frontage, a long boundary can result in a higher charge than a short one.
The Appeal and City Council Response
Hutchens took the case to Denver's Department of Transportation and Infrastructure, arguing that a fee of that size would cut directly into programs like the field trips and camp scholarships that depend on the nonprofit staying close to break-even every year.
"Unfortunately, for me and you, there is no provision in the code for me to use to make the case for a nonprofit or charitable organization to receive a reduction or exemption in the sidewalk fees as it is currently written."
As Denver7 reported, that was the hearing officer's response after telling Hutchens her presentation had been extraordinarily clear. The hearing officer denied the appeal, citing the absence of a nonprofit exemption in the ordinance. Bluff Lake filed a second appeal on February 19.
The one development that shifted the story came from City Council. District 8 Council Member Shontel Lewis, who represents the area, said she was as surprised as Bluff Lake was when she learned the size of the bill, and wrote a letter of support for the nonprofit's case. As of the most recent reporting, she and her staff were still working with attorneys to determine whether a fix would require a formal carve-out in the ordinance or something handled at the policy level inside DOTI. No resolution had been announced by that point, and nothing more recent has surfaced since.
What This Means If Bluff Lake Is Already Part of Your Week
None of this has changed what you'll find on a visit right now. The trails are open, the new lobby is staffed on its posted seasonal hours, and the boardwalk over Sand Creek is holding up well after February's improvements. The bigger question is what happens if the fee stands. Hutchens has been direct that the nonprofit runs close to net zero most years by design, meaning a bill of this size isn't an inconvenience so much as a real threat to the scale of programming Bluff Lake can keep offering for free.
For a lot of Central Park households, a stop at Bluff Lake is already stitched into a weekend that includes other things on the neighborhood calendar, whether that's the Central Park Farmers Market on Sundays or the free outdoor concerts the Master Community Association runs on the South Green through September. Bluff Lake isn't listed on the MCA's own calendar the same way, since it operates independently, but it functions as the same kind of shared civic space, and its financial footing affects whether that stays true.
The outcome of the second review may affect Bluff Lake's future decisions about hours, programming, and scholarship camp spots, given the potential budget impact of the fee.
