Commissioners in Nevada's Clark County have approved a development agreement with the Oakland Raiders that spells out public safety and infrastructure improvements in and around the stadium that the team will pay for.

Commissioners on Wednesday unanimously approved the agreement.

The document calls for widening sidewalks, improving roadways, installing and modifying traffic signals, and building any necessary pedestrian bridges.

The team has agreed to install at the stadium about $1.4 million worth of public safety equipment, as well as an emergency operations center.

The Raiders plan to start the 2020 season at a new stadium that's being built across the freeway from the Las Vegas Strip.

The $1.9 billion project is partially funded by taxpayers.

The document does not include a finalized plan for thousands of county-mandated parking spots.
