Officials in Mayor Muriel E. Bowser’s administration are looking to curtail the budget for the city’s visit to the South by Southwest festival next month, forcing economic planners to reconsider their plans for five days of events that would have cost nearly $500,000.

The nonprofit Washington, DC Economic Partnership was told during a meeting Wednesday to prepare for as much as $150,000 to be cut from its planned $475,000 budget, said marketing director Julie Weber.

A spokesman for the Office of the Deputy Mayor for Planning and Economic Development would neither confirm the size of the cut nor comment further.

The economic partnership and deputy mayor’s office have collaborated on the District’s presence at the music, film and innovation fair since city representatives first attended in 2013. The money comes almost exclusively from city coffers.

Economic development officials under former mayor Vincent C. Gray (D) had increased this year’s South by Southwest budget in a quest to attract more attention to the District’s burgeoning technology and art communities. In 2014, the city spent $168,672.

Joaquin McPeek, a spokesman for the deputy mayor’s office, said this month that Bowser’s administration was in the process of a “top-to-bottom review” of Gray’s entire economic agenda and would evaluate the impact that attending South by Southwest has on the local business community.

The biggest line item in the South by Southwest budget — $251,500 to transform a restaurant into a “We DC” lounge — will remain intact. The economic partnership has signed a contract for the venue, which will provide space for attendees to work and network, Weber said.

Instead, the cuts probably will come from events and other ancillary features that were planned for the lounge, which will be near the convention center in Austin. Weber said the partnership will look for lower-cost alternatives.

In interviews, officials at the economic partnership said the increase was necessary to compete with the growing number of cities and countries that attend the festival to pitch themselves as tech-friendly destinations.

The city planned to make 2,500 “new contacts” during the festival, some of them entrepreneurs who may be persuaded to start their companies in the District, said Tiffany Thacker, the partnership’s director of business attraction, technology and innovation. It’s unclear how the budget cuts might affect that goal.
