South Riding

South Riding: Loudoun County, Chantilly mail

South Riding is one of the more confusing addresses in the region — Loudoun County, Chantilly post. For choosing childcare, only one of those two facts matters.

South Riding is a planned community and census-designated place in Loudoun County, using ZIP code 20152 — but with a Chantilly mailing address, shared with parts of Fairfax County that also post as Chantilly.

So your post says Chantilly, your county is Loudoun, and every form you fill in for the next three years will ask you to pick one. Worth getting straight before you start comparing childcare.

Why the county, not the postmark, is the one that counts

Anita is voluntarily registered with Loudoun County. If you live in South Riding, that is your county — the same jurisdiction, the same registration, no cross-county wrinkle at all, whatever your envelopes say.

The drive

South Riding sits just east of Stone Ridge, the two separated by Route 50 and the newer Dulles South development in between. It is a short hop west rather than a commute — and, usefully, it is the opposite direction to the eastbound morning traffic most South Riding parents are about to join.

That's the quiet advantage: drop off going west, then turn around and go east with everyone else, having already handed over.

What you'd be driving to

A short hop west across Route 50.

Infant care →

From six weeks. One caregiver all day, naps on your baby's rhythm rather than a room's.

Toddler care →

One to two. Fresh air, block towers, and sharing that isn't optional in a group of three.

Two to three →

The year before preschool, spent as the eldest of three rather than one of twelve.
