A long-awaited project to prevent flooding in Murrieta and Temecula, and separate projects to replace bridges serving Riverside, Jurupa Valley, and Norco, could be delayed if the federal government shutdown continues.

The prospect of the now 32-day shutdown affecting infrastructure projects came up on Jan. 15, during a brief presentation by County Executive Officer George Johnson to the Board of Supervisors.

Though leaders in the Senate said Tuesday they’ll hold a test vote this week on bipartisan legislation that might temporarily re-open the government, there’s no sign that Democrats and President Donald Trump have reached a long-term compromise in their stand-off over $5.7 billion for a wall to cover part of the Mexican border. That means some projects and programs in Riverside County that get federal funding remain vulnerable to delays or interruptions.

The county’s Transportation and Land Management Agency and the Flood Control and Water Management District are processing several projects that require reviews and “approvals of federal permits,” Johnson told supervisors in mid-January.

“Without (U.S. Fish & Wildlife Service) involvement, we could have a number of significant transportation and flood control projects delayed. So we’re very concerned about those projects moving forth through the process.”

County spokeswoman Brooke Federico identified some specific projects that could be at risk of delay if the shutdown extends into next month or beyond:

The Murrieta Creek Flood Control, Environmental Restoration and Recreation Project, which has been on the drawing board for more than 20 years. When completed, it will widen the creek through Murrieta and Temecula and make other improvements to prevent a repeat of 1993 flooding that killed six and caused millions of dollars in damage.

The Mission Boulevard Bridge project, which would replace an existing bridge over the Santa Ana River between Riverside and Jurupa Valley. About 25,000 vehicles a day use the bridge as of 2015, county figures show, and the new bridge will be wider and better able to withstand an earthquake.

A project to replace the Hamner Avenue bridge running parallel to Interstate 15 in Norco. “The purpose of the proposed project is to replace the existing structurally deficient and functionally obsolete 76-year-old bridge with a new, longer, and wider bridge to provide enhanced public safety and traffic circulation in the area,” read a project description on a county website.

Shoulder widening on Gilman Springs Road between State Route 79 north of San Jacinto and Alessandro Boulevard in Moreno Valley. The widening is part of a multi-part project to make the road safer.

Infrastructure is just one aspect of county government affected by the shutdown. Another is food for the county’s neediest residents. Johnson said there’s enough funding in the Supplemental Nutritional Assistance Program, or CalFresh, to feed impoverished county residents only through the end of the month.

“If there is not funding restored, that program could be at risk in February,” he said. About 4 million Californians are getting early disbursements of CalFresh funds before money runs out.

Another safety net program that could be hindered if the shutdown continues is housing. Johnson said he’s “very concerned” that funding for federal housing vouchers could be suspended. As of December, Riverside County had about 8,500 “Section 8” vouchers that help people in need pay rent, with half of those going to the elderly or disabled.
