SCOTTSBLUFF, Neb. (AP) — A western Nebraska natural resources district is raising funds for a solar-powered, geothermal-heated greenhouse to grow oranges, lemons and other tropical fruit.

The North Platte Natural Resources District’s greenhouse project would include an outdoor learning facility to promote the district’s research and education goals.

Solar panels on the greenhouse would provide the $500 worth of electricity needed to maintain the temperature at 54 degrees.

The greenhouse would measure 126 by 17 feet and stand 14 feet high. It’s expected to have room for up to 21 trees.

More than 20 local donors have contributed to help match a grant from the Nebraska Environmental Trust. The project is expected to cost about $75,000.

Construction would begin in the spring, pending expected approval of the grant.

OMAHA, Neb. (AP) — A construction and engineering company is moving its new headquarters to downtown Omaha.

Kiewit Corp. reached a “memorandum of understanding” with Mayor Jean Stothert on Tuesday. The city will vacate the area near the development and help the company acquire the rest of the land it needs. Officials say the company is working to purchase one more parcel of land.

The downtown location is near the company’s training center that opened in February.

The office building and parking garage will be able to hold up to 650 people. The project may cost as much as $76 million.

Kiewit Corp. has hired Noddle Development Co. and architecture firm HDR Inc. for the project. The company may be able to move into the facility as early as 2020.

LINCOLN, Neb. (AP) — Nebraska’s 911 director is proposing a plan that would enable emergency reporting via text, photo or video.

Director David Sankey updated Nebraska lawmakers Wednesday on a plan to implement an upgraded 911 system statewide in 2019.

The system would cost an estimated $6.5 million annually and be funded through an existing monthly surcharge on wireless phones. Sankey says the Public Service Commission has a $12 million reserve which would be used for the upgrade.

The system would also link to geographic information system mapping, which would help dispatchers pinpoint a call location if callers can’t talk or don’t know their addresses.

About 80 percent of emergency calls in the state are made on mobile phones, many of which have multimedia functions.
