Daylighting creeks in Salt Lake City: Creating the Three Confluences Park

Last Saturday was the Celebrate at the Confluence event sponsored by Seven Canyons Trust, held at Three Confluences Park on Salt Lake City's West Side.

Seven Canyons Trust worked with the city to create the park by daylight the confluence of Red Butte Creek, Emigration Creek, and Parley's Creek at 900 West  ("Salt Lake City’s newest park is now open — see where three creeks meet on the west side," Salt Lake Tribune).  It opened in 2021.

The Trust grew out of a University of Utah planning design studio, which focused on the concept of daylighting creeks throughout Salt Lake Canyon.

The Wasatch Front is full of canyons and creeks.  The creeks, fed by snowmelt and rain, empty into the Jordan River which in turn flows into the Great Salt Lake.  Area communities capture this for the bulk of their water consumption.  (Once they are past the canyon, rain and stormwater, plus water releases from the canyons, make up the water flow.)

An 1800s citizen movement to protect the watershed.  Because of citizen concerns in the late 1800s about the quality of water supplies because the creeks and rivers were mostly used for dumping waste including dead animals, and the denuding of canyon forests for wood, they advocated for the creation of national forests as a way to protect the water supply.

Today Utah is a leader in trying to overturn federal ownership of public lands.  These days that's particularly ironic, because at the State level and the State's representatives in Congress, including the particularly odious Senator Mike Lee, Utah is a leader in trying to get federal public lands given to the state.  And the state (and Senator Lee) want to develop these lands as much as possible ("Thanks to Utah, Americans are about to lose their public lands," Moab Times-Independent).  

For example, the State supports the reduction in size of the Grand Staircase-Escalante National Monument ("Grand Staircase-Escalante National Monument Under Attack from Utah Members of Congress," Earthjustice).  And it suggested that the federal lands in the Big and Little Cottonwood Canyons--also used by for profit ski resorts in the winter, should be converted to state control.  To what ends...?

The State of Utah funded an ad campaign promoting its preference for federal lands being "returned" to the state.  Note that the State Constitution says federal lands should always be federal ("Here’s how much Utah is spending on a public relations campaign for its lawsuit seeking control of public land," Salt Lake Tribune).

Forest Service changes to increase for profit use of forests at the expense of conservation and public use.  Moving the US Forest Service to Utah ("The Forest Service Is Moving to Utah. Here’s What That Means for Our Public Lands," Outside) and the firing of scientists there ("Forest Service Sheds Research Capacity in Move to Utah," PEER) furthers this agenda.

How the Trump Administration is selling the move: "USDA Prioritizing Common Sense Forest Management, Moves Forest Service."

Undergrounding into pipes creeks and rivers.  But I digress.  In many urban areas, starting in the 1800s, creeks and rivers were covered and diverted into underground pipes.  

In DC, that's happened with Tiber Creek.  Someone who worked in a building abutting the old creek said you could hear it sometimes.  

In my Manor Park neighborhood, a creek at Fort Slocum was undergrounded--but the area still has a high water table and flooding--we had to install two sump pumps as a result of that and increasingly "robust" rain events.

DC still has other streams, even if it doesn't have an active daylighting program.  The Anacostia Watershed Society, Anacostia Riverkeeper, and Washington Parks & People lead efforts to remove litter and improve water quality for creeks that run into the Anacostia River.

Rock Creek Conservancy does the same for the DC and Suburban Maryland sections of the Potomac River Watershed, alongside the Potomac River Conservancy.

RFK Jr. may be willing to swim in it.  I think it's still premature ("Kennedy Swims in Washington Creek That Flows With Sewage and Bacteria," New York Times).  But ever closer, at least for the River, except that it took a major step backwards when a wastewater line burst, flowing into the River for weeks before it was repaired and contained ("A Huge Sewage Spill Is Over, but Contamination Lingers in the Potomac," NYT).

Daylighting.  For 20ish years at least, there has been a movement for daylighting--restoring these creeks and rivers.  Seoul is particularly famous for removing a freeway that had been built on a river.  In 2020, the Catharijnesgel Canal in Utrecht, Netherlands, was restored after being filled in during the 1970s to create a 12-lane freeway.  Etc.  

Before and after, Cheonggyecheon Restoration Project.

I think I first came across the concept in an issue of the Urbanite, a magazine that focused on Baltimore urbanism, which sadly went defunct as a result of the 2008 Great Financial Crisis.  

In "The Urbanite Project 2010" "Architect Gabriel Kroiz and environmental lawyer Eliza Smith Steinmeier proposed daylighting Harford Run, a stream that runs under Central Avenue, and turning it into a lively community recreational space."

Jordan River.  Separately the Jordan River Commission has been charged with restoring the Jordan River (and Utah River in Utah County) as it flows to the Great Salt Lake.  One thing they did that's really cool is the Jordan River Parkway trail along the River from Utah Lake in Utah County to the Great Salt Lake in Davis County--I've ridden parts of it but then I got sick and couldn't bike ride--over 60 miles.
