From The Denver Post (John Aguilar):
…city leaders say they are increasingly frustrated by Larimer County’s unwillingness to let them build a critical pipeline that would carry the water from the Cache La Poudre River near Fort Collins to Thornton — so much so that they have started alerting developers that the city may have to stop issuing building permits.
The new language warns that “the City does not guarantee capacity in its water or wastewater systems for proposed or future developments.”
Among the projects at stake for the state’s 6th largest city is dense multi-family housing planned around new N-Line rail stations that just went operational in September.
That’s frustrating to Thornton Mayor Jan Kulmann, who points to the thousands of acre-feet of water the city owns free and clear in the Cache La Poudre River northwest of Fort Collins — water rights it purchased more than three decades ago…
The answer goes back to February 2019, when the Larimer County commissioners unanimously voted to deny Thornton a permit for a 72-mile-long pipeline the city wants to install to carry that water to this suburb of 140,000. Jeff Coder, Thornton’s deputy city manager of city development, said the denial essentially holds Thornton’s growth plans “hostage.”
The city has enough water in its portfolio to supply 5,000 additional housing units, he said, or approximately 160,000 residents. The city’s long-term vision is for a population of 240,000 by 2065.
While no builders have pulled out of the city, Coder said, that day may not be far away. Maybe as soon as 2024 or 2025, he said.
“It’s understandably creating a great deal of concern,” he said. “In fairness to those who are making significant investments in our community, we don’t want someone who has gone through the approvals process expecting to get a building permit to have us at the last minute tell them we can’t because of this water issue.”
We want to prepare people for a worst-case scenario.”
The obvious solution, [Gary Wockner] said, is for Thornton to let its water flow down the Poudre through Fort Collins — “use the river as a conveyance” — and take it out further downstream near Windsor, obviating the need for a $450 million pipe that will require trenching and burial across 26 miles of Larimer County…
The city counters that allowing its share of water to flow through Fort Collins — and past several water treatment facilities — would severely degrade its quality and cost the city dearly to clean it. Emily Hunt, deputy infrastructure director for Thornton, said the river option was merely one of a number of alternatives the city put on the table as it was firming up plans to access its water.
“We specifically picked a site that was above urban impacts and the price we paid reflected that,” she said. “If we wanted a low-quality source that we clean up later, we could have done that and paid less money.”
According to the city, Thornton paid $578 million for 289 shares of water and storage rights in the Poudre River, along with $92 million for more than 18,000 acres of farmland in Larimer and Weld counties, where it has been sending its Poudre shares by ditch over the last 30 or so years.
But that level of investment wasn’t enough to sway the commissioners in Larimer County last year.
Outgoing Commissioner Steve Johnson said then that the proposed 48-inch diameter pipe, which would run across the northern edge of Fort Collins to Interstate 25 before turning south toward Thornton, ranked as one of the most contentious issues he had ever seen raised in the county.
But just this past September, the same commissioners voted 2-1 to approve a 1041 permit for the Northern Integrated Supply Project, a controversial $1.1 billion water storage initiative that would create Glade Reservoir northwest of Fort Collins and a second reservoir out on the eastern plains.
It also involves several water pipelines running through Larimer County.
Thornton recently included the NISP approval in its court filings appealing Larimer County’s denial of its pipeline project, citing it as evidence that the commissioners’ 2019 decision was “arbitrary and capricious.”
