DENVER (KDVR) — Mayor Michael Hancock provided an update Thursday on the city’s efforts to shelter an influx of migrants from the southern border and issued an emergency declaration for the city and county.

According to the city, more than 600 migrants have arrived in Denver since Dec. 2, and more than 900 total have arrived in the past several months.

“This influx of migrants, the unanticipated nature of their arrival and our current space and staffing challenges have put an immense strain on city resources, to the level where they are on the verge of reaching a breaking point at this time,” Hancock said.

Hancock said the declaration would help secure resources to support the migrants.

The city has spent more than $800,000 to shelter the migrants so far. An update said that amount was expected to increase significantly.

Two emergency shelters and a reception center were opened in Denver to accommodate the arriving migrants. The first shelter was at capacity as of Thursday, Hancock said.

Hancock said 247 migrants arrived in the city since Monday. An update said city and local partners were sheltering 404 migrants as of Thursday.

Hancock asked that nonprofits and volunteers go to denvergov.org/oem and find out how to help.

A drop-off location for physical donations was set up by the city at Iglesia Ciudad de Dios at 5525 W. Warren Ave. The church will accept donations Tuesdays and Wednesdays from 4 to 7 p.m.
