Dreyfuss + Blackford’s science museum enlivens Sacramento riverfront


Longtime residents of Sacramento and generations of commuters passing via the area know precisely the spot.

Joined by a cluster of finances motels on an remoted, wedge-shaped swath of land squeezed between Interstate 5 and the Sacramento River simply south of the place it meets the American River, for many years has stood as town’s most conspicuous—and enigmatic—blighted constructing: a stately, William Polk–designed Beaux-Arts energy station accomplished in 1912 as a shining exemplar of the Metropolis Stunning motion that has been left forsaken for the higher a part of the final 70 years, fenced-off and frozen in a state of dilapidation inside a contaminated, flood-prone web site.

Nevertheless, these passing by the Pacific Gasoline & Electrical Firm’s outdated River Station B in current months have doubtless observed a change. Preceded by a flurry of building work that kicked off in 2018, the Nationwide Register of Historic Locations–listed construction’s decades-spanning run as Sacramento’s most seen deserted constructing lastly come to an finish late final yr. The fences have come down and the graffiti has been scrubbed away within the long-awaited redevelopment of the five-and-a-half-acre web site into the SMUD Museum of Science and Curiosity, or MOSAC.

Mixing adaptive reuse with new building, the greater than 15-years-in-the-making transformation of River Station B was led by native structure and planning agency Dreyfuss + Blackford. To the agency’s credit score, the resuscitated web site is not any much less rubberneck-inducing from the freeway than it was earlier than due to a zinc-clad hemispheric dome that now rises above the Sacramento River alongside the painstakingly restored energy station.

“All although building, I’d say ‘I’m engaged on the Museum of Science and Curiosity, it’s the constructing by the river’—and that’s all I’d should say,” Chris Holt, venture supervisor with Dreyfuss + Blackford, relayed to AN. “Everybody knew precisely what constructing we had been speaking about. And everyone was excited that one thing was being carried out with it.”

“We had been apprehensive that folks would veer off the highway throughout building due to what they had been seeing,” added Jennifer Costa with amusing. An affiliate and venture supervisor with Dreyfuss + Blackford, Costa has labored on the rebirth of River Station B in its a number of iterations, together with as historic preservation architect.

Full STEAM forward

The long-awaited November 2021 public debut of Sacramento’s $40.8 million new STEAM-focused instructional establishment—it was beforehand often called the Powerhouse Science Heart being rebranded and renamed in 2020 as MOSAC—marks a brand new period for the ruinous riverfront web site following a string of failed redevelopment schemes proposed after the property was first bought by the State of California in 1960 from the AMC scrap steel firm; AMC had acquired the location from PG&E three years prior. (Throughout its temporary possession, AMC introduced down the facility plant’s smokestacks and gutted its inside, large boiler and generators included, with plans to make use of it as a short lived warehouse house.)

Scrapped proposals for the location embody a railroad museum within the Seventies, a classic automotive museum within the mid-80s, and the Water Palace, a ‘90s-era scheme for a brand new riverfront headquarters for the California Division of Water Assets that was in the end shelved as a result of web site’s precarious location inside a high-risk flood plain. (Dreyfuss + Blackford additionally helmed the design for that never-realized effort.)

In 2000, following 4 a long time of state possession and a handful of never-realized revitalization plans, hazardous waste cleanup work wrapped up and the location was deeded to the Metropolis of Sacramento. This transformation of fingers spurred a renewed seek for viable redevelopment proposals. Amongst them was a imaginative and prescient from Evangeline Higginbotham, the late govt director of Sacramento’s Discovery Museum Science & Area Heart, the predecessor group to the Powerhouse Science Heart, now MOSAC. With the Discovery Museum trying to develop out its then-current dwelling, she proposed turning the blighted River Station B web site right into a regional science schooling and exploration hub. Not like earlier proposals, her imaginative and prescient held due to a public-private partnership between the Science Heart, the Metropolis of Sacramento, the Sacramento County Workplace of Training, and the Sacramento Municipal Utility District (SMUD).

Dreyfuss + Blackford, in its position as each venture architect and historic preservation architect, accomplished its first conceptual design for the longer term Powerhouse Science Heart web site in 2007. The science heart complicated was subsequently redesigned twice—in 2011 and 2014—with the ultimate iteration of the design lastly transferring ahead in 2016 after town dedicated to further funding for the fits-and-starts-prone venture. MOSAC now serves because the anchor of the primary accomplished first part of town’s Robert T. Matsui Waterfront Park. Bringing the panorama as much as the extent of the levee, the park is an enchancment venture initiated by town following the development of a brand new consumption level for a water remedy plant positioned straight reverse I-5 from the redevelopment web site.

“It was in actually tough form,” Costa mentioned of the outdated energy station’s situation when the agency was first tapped for the bold riverfront infill effort. “And we’ve been in a position to watch it degrade over time, notably Jason

and I since we’ve been on the venture the longest.”

Referring to the riverfront space simply north of Previous Sacramento as “as soon as very downtrodden,” Silva credit the redevelopment of the River Station B web site for serving to to spur different north-of-downtown revitalization efforts equivalent to 244-acre Sacramento Railyards, one of many largest sustainable improvement initiatives in the US. “It’s actually been a catalyst as a result of the entire downtown area principally ended at Previous Sacramento, which is aligned with the downtown grid to the south of the location. However all the space was just about deserted to a level, and this was simply a type of blighted spots alongside the best way.”

“Town had tried and labored on it,” Silva added. “But it surely wasn’t till now that this has turn out to be actually a part of the regeneration of that space.”

Crumbling cartouches and levee issues

Bounded by I-5 and the river, the island-like improvement zone—each a brownfield and former Superfund web site—introduced the design crew with appreciable challenges. As Silva defined, the world the place the crew might work was restricted attributable to presence of “off-limits” hazardous waste caps; because of this, the design of the power was guided by the tough, constricted nature of the location. Additionally proving to be a problem was assembly the “typically altering” circumstances established by the U.S. Military Corps of Engineers, which oversees a 12-mile levee system that straight abuts the historic energy station.

The Military Corps of Engineers had a “necessities for a way we tackle our construction relative to their levee,” defined Silva. “We needed to do sheet pilings, that may have structurally separated the levee from the muse and the load of the constructing. This was in order that the constructing as soon as accomplished wouldn’t, with liquefaction, undermine the levee due to the load of the constructing pushes down and may pull the levee to failure.”

Becoming a member of technically complicated engineering issues, exhaustive environmental mitigation and historic preservation performed main roles within the transformation of the decaying Traditional Revival energy station. Vital efforts together with demolishing the construction’s present roof and bringing down the structurally unsound east wall, which Holt described as “type of a present that allowed the contractor to do a number of issues that they hadn’t discovered learn how to do.”

One other effort concerned replicating the concrete construction’s signature’s signature ornamental thrives: a crumbling, forged stone cartouche positioned above the facility station’s unique entrance entrance. With the help of native artist Stephanie Taylor, it was recreated utilizing glass-fiber strengthened concrete.

“That’s a very attention-grabbing story that in a roundabout way encapsulates the story of the venture itself,” mentioned Holt of the cartouche replication. “We needed to maintain it and needed it to be restored to its earlier grandeur, noting that the unique design and building of it wasn’t the best. However we needed to place it again as shut as we might to what it was.”

And whereas they don’t function the principle MOSAC entrance, the monumental, four-leaf doorways straight beneath the cartouche operate as an emergency technique of egress and can be opened throughout stretches of agreeable climate and for particular out of doors occasions held alongside the facet of the constructing. “We didn’t wish to simply put again a daily set of exit doorways,” mentioned Holt. “We needed it to be one thing particular.”

Changing the cavernous inside areas of the previous energy station right into a multi-level exhibition space turned out to be one of many extra easy parts of the venture.

“The big volumes of the powerhouse actually suited themselves to this,” added Costa. “From the get-go, we all the time knew we needed displays within the historic constructing–—they’re simply giant open areas.”

MOSCAC’s major everlasting displays are: Vacation spot Area, Well being Headlines & Improvements, Water Problem, Nature Detectives, Powering Change, and Constructing Sacramento. The historic constructing additionally contains house for non permanent touring exhibitions and a makers lab.

As for the 22,000-square foot addition, its program contains devoted classroom areas, administrative workplaces, café, present store, and a 122-seat planetarium, the UC Davis Multiverse Theater, that ranks as the most important attraction of its type within the area. Guests enter MOSAC via a glassy entry plaza on the new constructing earlier than finally discovering their solution to the exhibition areas throughout the adjoining historic construction. As famous by AN when the design was first revealed, the brand new constructing is deliberately deferent to William Polk’s classical design.

“As illustration of our place within the universe, the facade and constructing mass are sectioned by a number of planes, creating steady vector strains that reach throughout the constructing and web site,” the agency defined in a press launch. “From satellites to world landmarks, the strains kind connections with native and world factors of curiosity.”

Going platinum

The MOSAC venture is LEED Platinum–licensed, thanks partly to an on-site stormwater remedy system, biodiversity-bolstering native landscaping, and a high-efficiency HVAC system. “We additionally utilized a federal Superfund web site that was additionally brownfield and derelict, and we reused the constructing considerably—and that went a good distance,” mentioned Holt of the venture’s LEED Platinum bona fides. In whole, roughly 96 p.c of the historic constructing’s present partitions and flooring had been reused.

Working alongside Dreyfuss + Blackford to reimagine the location and obtain LEED Platinum within the course of was a bigger venture crew that included normal contractor Otto Building together with Jacobs (panorama architect), Buehler Engineering (structural engineer), Capital Engineering Consultants (mechanical engineer), the Engineering Enterprise (electrical engineer), NV5 (civil engineer), Simpson Gumpertz & Hege (exterior repairs and waterproofing), and Charles M. Salter Associates (acoustics). Pennsylvania-based projection dome specialists Spitz, Inc. led the design of the UC Davis Multiverse Theater.

Holt famous that one other side that helped the venture attain Platinum standing was Sacramento Regional Transit’s launch of a free, on-call shuttle to MOSAC and Robert T. Matsui Park, which can even dwelling to a forthcoming cherry blossom park from the Sacramento Tree Basis. Dubbed the Hanami Line, this new civic collect place is ready to interrupt floor simply south of MOSAC later this yr.

Whereas simple to entry by non-public automotive or by bicycle through the American River Bike Path (there’s each a brand new floor parking zone and ample bike parking), the location isn’t at the moment served by a bus line. “There are a few decrease revenue neighborhoods outdoors of strolling distance, however not far sufficient away to get of their automotive and drive. And so to have the ability to leverage that [the shuttle] goes to be nice for the group,” Holt mentioned.

Referring to the constructing now often called MOSAC as a “ardour venture for the workplace,” Costa emphasised the crucial position that the redevelopment of a distinguished native eyesore right into a group asset and regional vacation spot has performed within the rebirth of a once-neglected stretch of the Sacrament riverfront. It’s a venture, that as she defined it, hits near dwelling. “We’re the architects, however we’re additionally a part of this group,” she mentioned. “We stay right here and are elevating households right here and selecting to stay our lives right here.”
