Renting portable offices gives your business more workspace, breakrooms, pop up stores, security booths and more, without the cost and red tape associated with constructing building additions.

With us, you get a dedicated account manager you can rely on, so you can focus on running your business than waste time with a different person every time you call that doesn't know or care as much.

We prorate your rent by the day after the first 28-day billing cycle, so you don't have to pay for a full month when you only have your mobile containers and offices for a few days.

While other companies may be able to do small container modifications, most don't have an in-house fabrication staff or 90,000 sq ft fabrication facility like we do. As a result, they outsource the work on your custom container, so you don't know who's actually building it.

Rest assured knowing your modified shipping container will be built to the highest quality standards. Our certified weld and quality control inspectors check every step of the fabrication process to ensure everything is structurally sound and built to your specifications.

Rancho Cucamonga, California, Feb. 22, 2023 (GLOBE NEWSWIRE) --

Rancho Cucamonga, CA – A tree service provider in Southern California, Tree Service Experts Rancho Cucamonga, is pleased to introduce its new service designed to assist customers in identifying and removing invasive tree species. Under the guidance of CEO Gunther Gus, the company has developed a comprehensive program that enables homeowners to quickly and safely remove these trees from their properties.

Through the new service, Gunther Gus and his team of experienced tree professionals can accurately identify a wide range of invasive species and work with the customer to develop the most effective removal plan. In addition, the company uses state-of-the-art technology to track the progress of each project, providing customers with easy-to-understand results.

Tree Service Experts Rancho Cucamonga offers friendly and knowledgeable customer service that helps customers make informed decisions about their property's trees. With its comprehensive list of services, this leading tree service provider will meet all tree care needs, especially when protecting native trees from the harmful effects of invasive species.

Invasive species are non-native trees that can cause environmental damage or harm to native trees and animals. These species often spread quickly and compete with native species for resources such as light, water, and space, resulting in the displacement of native species and disruption of natural ecosystems.

"We have seen an increase in invasive species in Southern California over the past few years," said Gunther Gus, CEO of Tree Service Experts Rancho Cucamonga. "Our goal is to help our customers identify and remove these species before they become a problem. In addition, our new service is designed to provide homeowners with the knowledge they need to make informed decisions about their trees."

What we know about the high-speed rail from metro Los Angeles to Las Vegas

Construction on the highly anticipated bullet train that will transport Southern California residents to Las Vegas is expected to start in 2023 after Brightline, the company behind the project, inked a deal with a coalition of major labor unions.The coalition, known as the High-Speed Rail Labor Coalition, includes “13 rail unions representing more than 160,000 freight, regional, commuter, and passenger railroad workers in the United States,” a ...

Construction on the highly anticipated bullet train that will transport Southern California residents to Las Vegas is expected to start in 2023 after Brightline, the company behind the project, inked a deal with a coalition of major labor unions.

The coalition, known as the High-Speed Rail Labor Coalition, includes “13 rail unions representing more than 160,000 freight, regional, commuter, and passenger railroad workers in the United States,” a news release said.

“Americans want high-speed rail, and Brightline West and the High-Speed Rail Labor Coalition will deliver,” the High-Speed Rail Labor Coalition shared in a statement.

The project is expected to be completed in 2026 or 2027, the International Railway Journey reported.

A newly designed station that will be built in Rancho Cucamonga will connect the station to existing Metrolink service lines in San Bernardino and Los Angeles so residents in those areas can travel to Las Vegas using the bullet train, the Daily Bulletin reported.

“People who need to go back and forth from Las Vegas, there’s really no need to deal with a four-hour trip on the freeway anymore or even worrying about flying,” Rancho Cucamonga City Manager John Gillison told KTLA. “You can literally come out, get on the rail line and two hours later be in Las Vegas, or vice versa if you’re going the other direction.”

Trains will be able to reach speeds of up to 200 miles per hour as they travel the 218-mile rail line. Brightline says they will be a fully-electric and emission-free.

The project also aims to significantly reduce CO2 emissions by eliminating the need for 3 million cars to travel to Las Vegas. Company officials hope the project will eliminate 400,000 tons of CO2 from roads annually and relieve traffic on Interstate 15.

The $10 billion project investment will also yield economic benefits. Construction for the train will produce nearly 35,000 jobs, have a more than $10 billion financial return and permanently create 1,000 jobs once the project is complete, officials said.

Before reaching the Las Vegas Strip, the train will stop in Rancho Cucamonga, Apple Valley, and Hesperia and Victorville.

Brightline currently operates in Miami, Aventura, Fort Lauderdale, Boca Raton and West Palm Beach in Florida. The company plans to open an Orlando-based station in 2023.

After cool, mostly dry weekend in Southern California, another storm is on the way

After scattered showers dampened much of Southern California overnight and into Saturday, cool, dry weather is expected for the remainder of the weekend before another storm system moves in early the week of March 13.

About an inch and a half of rain fell over the San Bernardino Mountains on Friday, National Weather Service meteorologist Brian Adams said, as residents have continued to dig out from the snow dumped by February’s record-breaking storms.

As of Saturday evening, the entire Inland Empire, including mountain communities, had received less than an inch of rain for the day, according to meteorologist Samantha Connolly. Rainfall was progressively lighter in southern parts of the counties, around a tenth of an inch or so in total, compared to nearly an inch in the northern areas.

There were also no reports of new damage or flooding as of Saturday evening, said San Bernardino County Fire Department spokesperson Eric Sherwin.

At 10 p.m. Saturday, Sherwin said most roads would be reopened for residents and non-residents alike. There would still be closures between Crestline and Lake Arrowhead in the area known as “The Narrows” due to ongoing landslides, he said.

Another closure between Big Bear and Snow Valley will require visitors to use Highways 18 or 38 from Lucerne Valley or Redlands to visit Big Bear.

Sherwin added that ski resorts would be open Sunday.

Highway 38 had reopened in both directions from Mentone to Big Bear late Friday.

“Parking on roads is not allowed during snow conditions for ongoing plowing operations,” Sherwin said. “We want to welcome visitors into our resort areas, but we still have a lot of residents and a lot of neighborhoods that we need to continue removing snow from.”

In anticipation of next week’s storm, Sherwin said, the county’s Office of Emergency Services ordered sandbags, and extra fire resources would remain in place in the mountain communities.

Below the mountains, other Inland Empire communities including Ontario and Rancho Cucamonga received around an inch of rain Friday, Adams said.

“This was a pretty plain rain event that rolled through,” he said.

Coastline communities received about an inch of rain while a few inland areas received a little over two inches, including Porter Ranch in Los Angeles County.

A rock slide near the Morris Dam Reservoir led to the closure of Highway 39 on Saturday, according to Caltrans. Crews were working to clear the debris from the road.

A second, slightly larger storm system is expected to arrive Tuesday afternoon, delivering showers of 1 to 3 inches of rain over the coast, and 3 to 5 inches over the mountains and valleys, Adams said. Winds of 25 to 35 mph are possible, with gusts of up to 60 mph in the mountains.

“This storm has the potential for moderate to heavy rain across the San Bernardino mountains,” Adams said.

“We’re expecting this system to be stronger than this past storm,” he said, referring to the rain Friday night into Saturday morning.

In Los Angeles, the eastern San Gabriel Mountains were expected to take the brunt of the storm, with 3 to 6 inches of rain, said NWS meteorologist Kristan Lund.

On Saturday, however, the rainfall proved to be light.

Locations across LA County received less than an inch of rain, according to NWS meteorologist David Gomberg. The highest rainfall was measured at Northridge, which clocked in 0.56 inches total, he said.

Elsewhere in the valleys, in the LA metro area and the coasts, rain hovered anywhere from slightly above an inch to just under half.

The storm will continue through Wednesday evening before moving on, with clear skies and cool temperatures expected on Thursday and Friday.
