City of Aspen officials are hoping to reach an agreement by May 29 with the 10 opposing parties in two water court cases over the city’s conditional water rights tied to potential dams on Maroon and Castle creeks.

While that timeline may be ambitious, one of the parties in the two cases, Double R Creek Ltd., which owns a residential property that would be flooded by the Castle Creek Reservoir, recently signed a settlement agreement with the city.

“My client has settled and feels that the settlement is a good one for my client since it eliminates the threat of the development of that reservoir anywhere in the Castle Creek valley,” said Kevin Patrick, a water attorney with Patrick, Miller and Noto who represents Double R Creek Ltd. “We’re pleased.”

The potential Castle Creek Reservoir, which would store 9,062 acre-feet of water behind a 170-foot-tall dam 2 miles below Ashcroft, would flood portions of the residential property owned by Double R Creek Ltd.

It also would flood residential property across Castle Creek owned by Asp Properties LLC, which also is opposing the city in water court.

The Maroon Creek Reservoir would hold 4,567 acre-feet of water behind a 155-foot-tall dam, located just below the confluence of East and West Maroon creeks on U.S. Forest Service property, within view of the Maroon Bells.

Under similar settlement proposals sent to all the parties in the cases, the city would agree to move its conditional storage rights out of the Maroon and Castle creek valleys to six other potential locations in the Roaring Fork River valley, according to sources close to the court cases.

If the change in location of the water-storage rights is approved in water court, the city could retain the right to transfer as much as 8,500 acre-feet of water storage across those locations, down from the potential combined total of 13,629 acre-feet in Castle and Maroon creeks, but only in those six new locations.

The locations include the existing gravel pit in Woody Creek on land the city recently purchased for water storage next to the gravel pit, on the city’s golf course, on the Moore Open Space near the roundabout, on land near the Burlingame housing development and on the Cozy Point Open Space at the bottom of Brush Creek Road.

On May 29, city staff plans to present the signed agreement with Double R Creek Ltd. to the City Council in a regular public meeting for its final review and approval. They also are working to present signed agreements, or stipulations, with the other nine opposing parties in the cases, as well.

“We’re hopeful that when we come to council we’re going to have stipulations from all the parties,” said Margaret Medellin, utilities portfolio manager for the city. “And if we don’t, we will take what we have and continue to work toward a point of settlement.”

Outstanding areas of agreement among some of the opposing parties and the city revolve around assurances that the city won’t try and move its conditional rights, fail in its attempt, and then return to seeking to maintain its conditional rights in the Castle and Maroon valleys.

Patrick said the agreement he signed on behalf of his client includes those assurances.

The other parties in the two cases include two property owners in Maroon Creek, Larsen Family LP and Roaring Fork Land and Cattle Co., Pitkin County, the U.S. Forest Service, Wilderness Workshop, Western Resource Advocates, American Rivers and Trout Unlimited.

The city first applied for the conditional water storage rights for the two potential reservoirs in 1965 and the decree for the rights carries a 1971 priority date.

In October 2016, the city submitted two due-diligence applications for the reservoirs and the cases attracted opposition from 10 parties across the two cases.

In July 2017, the city announced its intention to move the conditional storage rights out of both valleys and has been in negotiations with the opposing parties in the case since then.

On Tuesday, the city’s water attorney, Andrea Benson of Alperstein and Covell in Denver, updated the Division 5 water court referee, Susan Michelle Ryan, on the city’s settlement efforts.

“Since the last status conference, I believe we’ve made some good progress toward settlement with all of the opposers,” Benson said.

Benson said in addition to having a signed stipulation with Double R Ltd., the city has also reached a “settlement in concept” with both Western Resource Advocates and Wilderness Workshop.

Will Roush, the conservation director at Wilderness Workshop, said his organization’s main goal in the cases has been “protecting those two creeks and ensuring that there wasn’t the possibility of building dams on either creek. Dams obviously fragment streams and the riparian habitat. So our goal has always been to protect the ecosystems of those two valleys.”

Paul Noto, a water attorney also with Patrick, Miller and Noto, is representing American Rivers, Trout Unlimited and the Roaring Fork Land and Cattle Co. in the cases.

“We’ve been working with the city toward settlement, and it seems like we’re making progress, and we hope to have the case wrapped up shortly,” Noto said Tuesday.

Medellin, who declined to discuss the specifics of the proposed settlements, said city staff has been “negotiating with council’s direction.”

She also said the city’s position is that all of the parties in the case need to agree to settle for the final deal to be struck.

“We think we’ve been able to come to a place where we are all going to get what we want, or close to it,” she said.
