Coors Field opened in 1995 and is the third-oldest ballpark in the National League behind Chicago’s Wrigley Field (1914) and Los Angeles’ Dodger Stadium (1962). The $tadium Game Part I: Amid another nationwide stadium boom, will Broncos build new home to land what Rockies have and what Nuggets, Avs are getting? Part II: Is Coors Field the model for publicly financed stadium success? How the Monforts struck gold in LoDo. Part III: Ball Arena was always window into downtown Denver land development for Stan Kroenke Part IV: New Broncos stadium? Inside the what, where and when for a decision. Rockies owner Dick Monfort envisions Coors as a “grand old ballpark” that could last for 100 years, but that requires upkeep. Denver-area residents own Coors Field and the Denver Metropolitan Major League Baseball Stadium District oversees the Rockies’ lease obligations at the ballpark. But over the first 30 years, the Rockies paid for the significant upgrades and construction projects at Coors while the stadium district helped fund more minor maintenance projects and upgrades. In 2017, the Rockies finalized a new 30-year lease agreement at Coors, keeping the club at the LoDo ballpark until at least 2047. The Rockies will pay for the bulk of the capital improvements, which are projected to be $200 million over the length of the lease. The Rockies contributed $125 million to fund maintenance and improvements while boosting their annual payments to $2.5 million from the previous $1 million. In trade, the Rockies were allowed to lease and develop a valuable plot of land directly south of the stadium for 99 years. That former parking lot was transformed into McGregor’s Square — an 818,000-square-foot residential, retail and entertainment complex.

District spokesman Matt Sugar said that much of the work at Coors over the next few years will be standard maintenance. “We’re not talking about a lot of bells and whistles,” he says. “We’re talking about expansion joists, plumbing fixtures and upgrading bathrooms.” Following are the major Coors Field renovations and improvements over the ballpark’s first 30 years: • 2005: Scoreboard replacement (Cost: $3.75 million) — The project included a new video scoreboard in left field and upgrades to the “ribbon boards” that run below the second deck. • 2013: Press Club Suites ($1.5 million) — The project converted more than 60% of the old press box into a bar, restaurant and seating area behind home plate at a level between the club level and main concourse. It’s now called the “PNC Press Club.” • 2014: The Rooftop ($10 million) — A 38,000 square-foot, multi-level, primarily standing-room-only bar that turned 3,500 right-field seats in upper right field into a party deck that Monfort said would add “another dimension” to Coors Field.

The increased height — from 8 feet, 9 inches to 16 feet, 6 inches in front of bullpens that run from right-center to close to center, and from 8 feet to 13 in the left field corner — was the brainchild of former general manager Jeff Bridich. • 2018: New scoreboard ($15 million) — A massive new scoreboard/videoboard measuring 8,369 square feet was installed in left field. It was 258% larger than the board it replaced. It has the shape of a mountain cutout, reminiscent of the club’s Rocky Mountain logo. The display is equivalent to 784 60-inch televisions. • 2018-19: Home clubhouse renovation ($3.9 million) — Completed in two phases, the players’ home away from home includes a new locker room, workout facility, training room, hot tubs/cold tubs, a dining room/lounge and various other upgrades. • 2017-19: Speaker installation ($1.3 million) — Completed in two phases, the new speakers enhanced the sound system within the ballpark. • 2019: Club-level concession renovations ($5.5 million) — Updated and enhanced the food and drink concessions at the club level. • 2020: Field replacement ($2.7 million) — During the 2019-20 offseason, a new boiler system was installed. In conjunction, a new hydronic heating system was installed underneath the playing field. That required the entire field to be dug up, rebuilt and resodded. • 2020: Protective netting extension ($421,000) — All major league teams installed netting down the baselines and to the foul poles to protect fans from getting hit by baseballs. • 2023: Upgrades and remodeling of suites. ($16.5 million) — The Rockies renovated the team’s infield suites, modifying the interior decor for spaces accommodating 12 to 60 fans.
