MORRISON — Denver officials Wednesday night laid out for a roomful of Morrison residents the city’s latest strategies for quelling noise issues at Red Rocks Amphitheatre.

“We know this is a hot topic,” Tad Bowman, Denver’s venue director for Red Rocks Amphitheatre, told them. “We’ve done a number of things to balance what you want with the fact that this is a business.”

The new rules — included in contracts for all 2015 performances — apply to various levels of sounds, including the bass levels, and late performance times that were at the heart of residents’ complaints.

Since at least 2013, the town of Morrison has asked Denver to address what neighbors of the venue feel is a recent increase in sound levels and, in particular, the reverberating bass felt during concerts. Residents singled out the increasing number of electronic dance music, or EDM, performances as the primary issue.

At the start of 2014, Denver released new rules for noise levels and earlier end times of performances, in addition to launching the study of noise levels throughout the year, but residents complained that still was not enough.

One key change in 2015 from the regulations imposed in 2014 is that the noise limits will apply to entire performances, not just to late hours.

Denver Arts and Venues executive director Kent Rice, who was in attendance Wednesday, said the new limits on bass noise will make a big difference. Specifically, they are below levels exceeded by many performances in 2014.

“The ceiling has been lowered,” he said, and artists must adjust the noise levels of their entire shows accordingly.

Also new is a provision that allows Denver to ban any artist that violates the regulation from the subsequent concert season.

The new regulations got the approval of the sound consultant that Morrison hired separately from the consultant that conducted Denver’s study.

Morrison Mayor Sean Forey said he trusts their judgment and looks forward to improvements.

However, some residents were still skeptical, saying Denver officials’ main concern was money, rather than quality of life. Some suggested that EDM shows be banned.

Jefferson County Commissioner Casey Tighe, who has been part of the ongoing conversation, remains optimistic.

“What I am hearing is that 2014 was better than 2013,” he said. “And I think that 2015 will be better than 2014.”
