Station Overview
Walnut/Diamond Bar Station serves both contract cities directly — the station carries both names for a reason — plus the unincorporated Rowland Heights area between them.
Neither Walnut nor Diamond Bar runs its own police department. Both contract with the Sheriff's Department, so every arrest inside those city limits is a county arrest handled from 21695 East Valley Boulevard.
Rowland Heights is the detail families miss. It is unincorporated county territory rather than part of any city, so a Rowland Heights arrest is booked here rather than by a municipal department.
The station handles the arrest, the booking paperwork, and short-term holding. Nobody stays at a patrol station; bookings not resolved locally move into the county system downtown.

A patrol station is not a visiting facility. Once someone is in county custody, visits are scheduled through the Sheriff's Department system.
Two published phone lines serve this station. If one goes unanswered during a shift change, try the other before assuming nobody is there.
The county inmate search can come back empty for hours after an arrest here, because the county record is created downtown at intake rather than at the station.
Transport downtown can leave sooner than expected, and station-level timing is never guaranteed. Call as soon as you know about the arrest — we work the station and the downtown facility at the same time.

Six real steps, from an arrest in Walnut, Diamond Bar, or Rowland Heights to release.
Arrest In Walnut, Diamond Bar, Or Rowland Heights
Both cities contract with the Sheriff's Department and Rowland Heights is unincorporated, so all three are county arrests from the first minute.
Booking On East Valley Boulevard
Identification, paperwork, and short-term holding happen at 21695 E. Valley Blvd. Call (909) 595-2264 to confirm someone is there.
Bail Set From The County Schedule
Bail comes off the Los Angeles County bail schedule at booking, so it is postable immediately rather than waiting for arraignment.
Post Before Transfer — The Fast Path
A bond posted while someone is still at the station skips the downtown intake queue entirely. This is consistently the fastest outcome available.
Transfer To The Inmate Reception Center
Unresolved bookings transport to 450 Bauchet Street for full county booking, medical screening, and classification.
Arraignment At Pomona Courthouse South
Diamond Bar cases are confirmed to Pomona Courthouse South, where a judge can adjust bail or grant own-recognizance release.
How To Post Bail Before County Transfer
Premium on a California bail bond is set by the rate filed with the Department of Insurance under Cal. Ins. Code §1800. The starting bail figure comes from the Los Angeles Superior Court’s felony and misdemeanor bail schedule, adopted under Penal Code §1269b, and review or reduction of that figure runs under Penal Code §1270.1.
Timing is the whole game at a patrol station. Bail posted before the transport downtown ends the matter in hours; bail posted after has to wait for county intake, medical screening, and classification.
Nobody needs to drive to East Valley Boulevard or downtown. Paperwork, signatures, and payment are handled remotely, and the bond is posted wherever the defendant actually is.
Because the figure comes off the county schedule at booking, there is no reason to wait for a hearing — and a judge can still adjust it or grant own-recognizance release at arraignment.
Qualifying cosigners can start as low as 1% down on approved credit.
If A Court Date Is Missed After Release
A bond written for Walnut/Diamond Bar Station stays live through every appearance until the case resolves. A missed date can mean a forfeited bond and a bench warrant the same day, with a limited statutory window to bring the defendant back before the forfeiture becomes a judgment against the cosigner.

City bail bonds pageBail FAQs
Why does this station carry two city names?
Because it serves both Walnut and Diamond Bar directly under separate LASD contracts, from one building on East Valley Boulevard in Walnut. Arrests in either city are booked at the same counter.
My relative was arrested in Rowland Heights — who has them?
This station. Rowland Heights is unincorporated county territory, so the Sheriff's Department has the case rather than any city police department.
Which courthouse hears these cases?
Pomona Courthouse South at 400 Civic Center Plaza holds confirmed jurisdiction over Diamond Bar. Walnut shares the station and is a high-confidence match for the same courthouse, but it is not independently named in the jurisdiction list, so we verify per case.
Can I post bail at the station itself?
Yes, while the defendant is still there — and that is the fastest possible outcome, because it skips the downtown intake queue. Once transport leaves for the Inmate Reception Center, the bond is posted downtown instead.
Which phone number should I call?
Either published line works: (909) 595-2264 or (626) 913-1715. If one goes unanswered around a shift change, try the other — or call us and we will make the calls for you.
