Riverdale, a small city built along one of northern Utah's busiest roads

Riverdale is a small city in southern Weber County, on the north bank of the Weber River, about twenty two miles north of Salt Lake City and just south of Ogden. It covers 4.6 square miles, with an elevation the city gives as a range across town, roughly 4,320 to 4,670 feet. City hall is the Civic Center at 4600 South Weber River Drive. Ogden sits to the north, South Ogden and Washington Terrace to the east, Roy and West Haven to the west, and the Weber River and the Davis County line to the south.

Three public bodies publish three current figures, and they do not quite agree. The 2020 census counted 9,343. The U.S. Census estimate for 2025 is about 9,200, a little lower. Riverdale City's own page prints 8,727, lower again. Use the Census figure to compare Riverdale with other cities, and treat the drop since 2020 as a small decline rather than a story about anyone. A fourth number sometimes seen, 9,279, is a five year survey average and should not be set beside the other three.

Because of one road. The state's labor department counts about 8,761 jobs inside Riverdale, close to one for every resident, which makes it the third largest job center in Weber County behind Ogden and Roy despite ranking ninth by population. Almost all of those jobs sit on Riverdale Road, the big box and restaurant strip that runs between Roy and Ogden and crosses two interstate freeways inside the city. That is a count of jobs and nothing more.

No. Newgate Mall's mailing address is Ogden, UT 84405, a ZIP Code that also covers Riverdale, but its parcel sits inside Ogden city. This is the clearest example of a rule worth carrying into any search here: a mailing address is not a jurisdiction. Riverdale shares that postcode with Washington Terrace, South Ogden and part of Ogden, and along this stretch of the valley the postal city and the actual city line disagree more often than not.

No to all three, and each one lives in a different neighboring city. There is no municipal pool, so the city buys pool time in Roy, which is where its own Fourth of July swim night is held. The nearest library branches are the Pleasant Valley Branch on Adams Avenue and the Southwest Branch in Roy. And there is no dog park inside Riverdale's three parks. This is worth knowing before you move: the everyday shopping is inside the city, but a few civic amenities are a short drive across the line.

Yes, Riverdale runs along the northern edge of the base, and the base itself lists Riverdale among its bordering cities. But no gate is in Riverdale; the nearest entrance is the North, or Roy, Gate in Roy, and everything past the guard post belongs to the Davis County side. For what an address near the base actually means, the planning department, not the base, holds the noise and accident overlay for any given parcel, and the base itself is covered on the Hill Air Force Base page.

One school stands inside the city limits and the rest of a child's schooling happens next door. Riverdale belongs to Weber School District, the county district rather than Ogden City's, and its one in city school is a kindergarten through grade six building. The state and the district both print its name as Riverdale School, though Riverdale Elementary is also in common use. The junior high and high school most Riverdale addresses feed toward sit on parcels inside Washington Terrace. This site does not rate schools; check a third party such as GreatSchools or Niche and confirm the boundary with the district.

Part of it is low ground toward the river bottoms, and that is exactly where a flood question belongs. The honest answer for any specific address is the federal flood map: look the parcel up by street address at FEMA's Flood Map Service Center, which returns the flood zone for that address. The higher ground away from the river is a different picture, so this is a parcel by parcel question rather than a whole city one.

Yes to both. Riverdale keeps its own fire department on Parker Drive, with ambulance service at the advanced EMT level and a heavy rescue capability that the county helps fund as a regional resource, which is more than a city of nine thousand usually keeps rather than contracting out. It also runs its own police department. The city bills its own culinary water, sewer, garbage and recycling, and buys just one service from a neighbor: pool time in Roy.
