INLAND VALLEY HUMANE SOCIETY &
S.P.C.A.
Animal Control
IVHS animal control officers and
personnel enforce the City’s animalrelated ordinances, prevent cruelty by advocating and enforcing state animal
protection laws, and investigate
nuisance animals. They also are tasked
with rescuing wild and domestic
animals, providing medical care,
shelter, and food when necessary.
IVHS Objectives
Provide a safe refuge for
all sick, injured, abused,
and abandoned animals
that have no other
alternatives.
Foster compassion for all
living things through
education and outreach.
Promote the health and
wellness of all pets in our
community by providing
accessible and affordable
veterinary care.
Reduce pet
overpopulation.
The Inland Valley Humane Society & S.P.C.A. (IVHS) is
a nonprofit organization that provides animal care
and control services under contract to Diamond Bar
and 11 other cities and unincorporated areas of San
Bernardino County. IVHS headquarters in Pomona is
located within approximately one mile of the city’s
border, offering convenient access for Diamond Bar
pet owners and rapid response to local enforcement
and nuisance-abatement issues.
The City’s annual service contract cost for Fiscal Year 2023-24 is $544,256. This is offset by licensing and
related service fees from gross service costs, bringing the annual total to $457,500 for Fiscal Year 2023-24.
Costs vary from year to year based on changes in
license fee revenue collected, percentage of IVHS
services consumed by residents, and any changes to
the City’s animal license fee schedule.
City of Diamond Bar - 2023 Public Safety Annual Report | 3 Adoptions
IVHS leads the community in finding homes for all
adoptable pets. In 2015, IVHS launched the “Getting
to Zero” campaign, a robust adoption outreach plan
with the goal of saving every adoptable pet in their
care. The adoption program features active social
media and internet-based outreach efforts that have resulted in increased adoptions for the last several years. IVHS got to zero euthanasia of healthy, adoptable pets in 2017, and has continued that same sheltering and life-saving practice today. All pets adopted through IVHS are provided with free food through its partnership with Royal Canin, two weeks post-adoption veterinary care through its partnership with VCA, and if having behavioral problems IVHS provides scholarship for Good Pups online training. To assist pet owners that must unfortunately relinquish their animal, IVHS offers the “Hometo-Home” program, an easy to use direct-to-adopter opportunity that allows animals to be re-homed without having to enter the shelter.
Licensing
IVHS is responsible for issuing dog and cat licenses
and collecting licensing revenue in the city.
Licensing of dogs four months and older is required
by state law. To better streamline licensing, IVHS
partnered with DocuPet for new licenses and
renewals. The DocuPet portal also allows residents
to have a simple and nationally recognized
website that provides a one-stop shop for licenses
and customizable pet tags that can be used to
reunify pets with their families.
Low-Cost Veterinary Services
IVHS opened its state-of-the-art Alex and Elisabeth Lewyt Medical Center in January 2023, and provides Diamond Bar pet owners the opportunity for low-cost spay/neuter and vaccine appointments, and other pet wellness needs. In addition, all animals are spayed or neutered, microchipped, de-wormed, and treated for fleas and ticks prior to adoption.
To reduce the growing number of cats, chihuahuas, and pit bulls that enter shelters each year, IVHS provides low-cost spay/neuter services under the “Big Meow”, “Chihuahua Challenge”, and “Pit Stop” programs, which are open to Diamond Bar residents at a reduced rate.
City of Diamond Bar - 2023 Public Safety Annual Report | 4 Community Outreach
IVHS offers a number of public engagement programs to Diamond Bar residents of all ages, including participation at City special events like the annual Halloween Party, special school presentations, pet therapy visits, and facility tours.

The Los Angeles County Fire Department remains engaged with the community, promoting fire and emergency preparedness through a number of outreach programs.
Multi-Jurisdictional Wildland Fire Preparation (San Bernardino, Orange, Los Angeles, Riverside - SOLAR)
On a quarterly basis, SOLAR fire agencies gather to enhance communication and partnerships in wildfire preparedness in Tonner Canyon. Tonner Canyon is a shared geographical area for the affected fire agencies.
Following the 2008 Freeway Complex Fire, the affected fire agencies met to discuss lessons learned. As a result, they formed a mutual threat working group to address protocols, communication skills, mutual and automatic aid agreements, pre-attack plans and improve unified commands.
Meetings of the SOLAR agencies provide an opportunity to collaborate on a plan of action with numerous incident commanders based on one unified command. 81 87 78

City of Diamond Bar - 2023 Public Safety Annual Report | 10 Annual Brush Clearance
Inspection Program
The Brush Clearance Program is
a joint effort between the Fire
Department, the County of Los
Angeles Department of
Agricultural
Commissioner/Weights and
Measures, and the Weed
Abatement Division.
The Fire Department’s Brush Clearance Unit (BCU) enforces the Fire Code as it relates to brush clearance on improved parcels. The BCU works closely with all county fire stations, coordinating inspections, providing training for fire station personnel and to support station compliance efforts.
On May 1 of each year, Diamond Bar Fire Stations begin annual brush clearance (defensible space) inspections, focusing on designated brush areas and high fire severity zones within the City. Required clearance of native vegetation and properly maintained ornamental vegetation is the first line of defense against wildfire.
Conscientious efforts on behalf of the property owner to comply with Fire Department requirements will greatly reduce the chances of fire spreading onto property. In 2023, over 3,500 inspections were conducted in Diamond Bar.
Diamond Bar Stations look forward to working with homeowners to ensure the risk of fire hazard is reduced on their property. The Fire Department’s website fire.lacounty.gov offers additional information and resources regarding annual brush inspections.
Community Emergency Response Team
Following a major disaster, fire and rescue
resources may be unable to immediately
respond to all those in need. In such a crisis,
it will be neighbors assisting neighbors until
emergency response personnel can arrive.
Community Emergency Response Team
(CERT) training provides residents with the
skills and tools necessary to take care of
themselves, their families, neighbors, and
coworkers in the event of a disaster.
City of Diamond Bar - 2023 Public Safety Annual Report | 11 The Fire Department offers free, FEMA-approved 20-hour CERT training to the communities served. Classes educate residents on hazards that may impact their area, and basic disaster response skills such as fire safety, light search and rescue, team organization, and disaster medical operations. Upon completion of the course, CERT members are better prepared to assist those in their home, neighborhood or workplace following an event when professional responders are not immediately available to help.
It is important to note that CERT volunteers do not work for the Los Angeles County Fire Department.
Ready, Set, Go!
Los Angeles County is one of the most
beautiful places to live, but for those
living in “wildland urban interface
areas,” it does not come without risks.
Drought and insect infestation has
made fire season year-round and
increased the ever-growing number of
wildfires.
The Fire Department, along with
partnering agencies, stand ready to quickly respond to contain wildfires, utilizing firefighting resources from the air and ground to help protect residents and property from wildfire. The Ready! Set! Go! Program was created to provide residents with critical information on creating defensible space around the home, retrofitting the home with fire-resistant materials, and preparing residents to safely evacuate well ahead of a wildfire.
Local fire stations encourage Diamond Bar residents living in brush areas and high fire severity zones to be ready and prepared by taking time to review the Ready! Set! Go! Program. To download a copy of the Ready! Set! Go! brochure, residents are encouraged to visit fire.lacounty.gov.
Family Instructions for Rapid Escape (F.I.R.E)
Each year in this country there are over 380,000 residential fires, causing more than 2,700 deaths and 12,000 injuries.
Kids are at greatest risk for death or injury in these fires. With recent changes to home construction and furnishings,
today’s fires burn hotter, spread faster, and churn out more toxic gases than ever before. In the past, residents had about 17 minutes to escape a house fire once their smoke alarm activated, but today that time has dropped to three minutes or less.
City of Diamond Bar - 2023 Public Safety Annual Report | 12 To help address the problem of fatal fires, the Los Angeles County Fire Department, is introducing a unique, new fire safety public education program called Family Instructions for Rapid Escape or F.I.R.E.
The guide provides simple steps on how to make a home “F.I.R.E.” ready, teaching new strategies, so residents can escape and survive if fire strikes. Residents can download a copy of both guides by visiting fire.lacounty.gov. The F.I.R.E. program was researched, developed and written by L.A. County Fire Department Captain Brian Cieslak.
Hands-Only CPR
Hands-Only CPR is different from conventional “mouthto-mouth” CPR and is designed to teach people basic CPR skills to aid a family member, friend, or other person in need. If provided immediately after sudden cardiac
arrest, Hands Only CPR (using chest compression only)
can double or triple a victim’s chance of survival until emergency responders arrive.
The Fire Department offers Hands Only CPR training to
residents during community events and public safety
presentations. In addition, Diamond Bar Fire Stations
conduct free training during the annual “Sidewalk CPR
Day”.
“Sidewalk CPR Day” is held during the first week of June and takes place at various sites across the county.
Safe Surrender
The Safely Surrendered Baby Law was created in response to the increasing number of newborn infant deaths due to abandonment in unsafe locations, and signed permanently into state law in January 2006.
The law's intent is to save lives of newborn infants at risk of abandonment by encouraging parents or persons with lawful custody to safely surrender an infant within 72 hours of birth to any fire station or hospital, with no questions asked. Station 120 has been a Safe Surrender site in recent years.
City of Diamond Bar - 2023 Public Safety Annual Report | 13 Explorer Program
The Fire Department Explorer Program is a
joint venture with “Learning for Life”
designed for youth, ages15-20, interested
in learning about a career in fire service,
and led by firefighters known as Explorer
Post Advisers. After meeting the
program’s entrance requirements,
Explorers have the opportunity to qualify
for a 12-day training academy held on six
consecutive weekends.
During the academy, Explorers are trained on firefighting skills, hose lay evolutions, ladder techniques, salvage operations, wildland firefighting procedures, proper use of firefighting tools and equipment, breathing apparatus use, and other related subjects.
Upon graduation from the academy, Explorers are qualified to ride along on an engine, truck or paramedic squad and respond to actual fire and medical emergencies.
During ride-alongs, Explorers use the training they received to assist Department personnel at emergency incidents and participate in other station activities and duties.
In addition to attending weekly meetings, Explorers are involved in various community service activities such as staffing booths during city functions, safety fairs, and demonstrations for public education events. Because of the Explorer Program, many have continued on to pursue a career in the fire service.
Junior Lifeguard Program
The Junior Lifeguard program is open to children between the ages of 9 and 17, teaching participants about beach and ocean skills such as water safety, physical conditioning, first aid, rescue techniques, CPR, and more.
Water Watcher
A program that reminds individuals the dangers of water and how children can drown without making a sound.
Encourages always having a designated Water Watcher
to supervise children, have a working phone nearby and
the importance of knowing how to perform CPR.
City of Diamond Bar - 2023 Public Safety Annual Report | 14 Sirens of Silence
The Los Angeles County Fire Department created Sirens of Silence to familiarize and expose individuals with ASD to first responders.
The program works with local organizations so children with ASD and their parents/caregivers can meet firefighters and lifeguards, see and touch the equipment and apparatus in a quiet, less stimulating setting.
Women’s Fire and Lifeguard Prep Academies
The Los Angeles County Fire Department Women’s Fire Prep Academy (WFPA) and Women’s Lifeguard Prep Academy (WLPA) were developed in collaboration with the Los Angeles County Women’s Fire League. The respective academies expose interested candidates to the duties and detailed responsibilities of the firefighter and ocean lifeguard positions.
Girls’ Fire Camp
This one-day camp introduces girls
between the ages of 14 and 19 to the
career opportunities of the Department
and gain some hands-on experience.
LOS ANGELES COUNTY SHERIFF’S DEPARTMENT
Contract Law Enforcement Program
Diamond Bar’s law enforcement services are provided by the Los Angeles County Sheriff’s Department under the Municipal Law Enforcement Service Agreement (MLESA) with the County of Los Angeles. The “contract law” model was dates back to 1954, when Lakewood became the first City to partner with the Sheriff’s Department.
Using this initial agreement as a template, 42 of the County’s 88 cities followed suit and joined the Contract Law Enforcement Program. The Contract Law Enforcement Program allows cities like Diamond Bar to develop a customized policing program at a more cost-effective rate when compared to a municipal department. The contract law model provides Diamond Bar with access to the full resources of the Sheriff’s Department, including, but not limited to Aero Bureau, narcotics, and the major crimes task force.
City of Diamond Bar - 2023 Public Safety Annual Report | 15 Diamond Bar/Walnut Station
The Diamond Bar law enforcement team is
based in the Diamond Bar/Walnut Sheriff’s
Station, located at 21695 Valley Boulevard
in nearby Walnut and can be reached by
phone at (909) 595-2264.
Expenditures
The City’s base contract law personnel cost for FY 23-24 is $7.9 million. This total represents nearly 25% of General Fund expenditures.
Since FY 2019-20, contract law personnel costs have increased by an average of 3.4% annually. Annual increases are due to factors including labor contract increases and LTF rates.
Law Enforcement Deployment and Volunteers
Personnel
Captain Steve Tousey leads Diamond Bar/Walnut Station, providing direct day-to-day coordination with Diamond Bar staff on law enforcement and crime prevention matters. Lieutenant Daniel Dail serves as Diamond Bar’s Service Area Lieutenant. 1 $6,920,414 $7,282,680 $7,232,714 $7,900,097
2019-20 2020-21 2021-22 2023-24
The City’s contract law expenses
comprised of the per-unit cost for each
deputy plus a percentage-based fee
known as the Liability Trust Fund (LTF). The
LTF is a County-controlled surcharge
applied to fund liability-related issues
resulting from the delivery of law
enforcement services to contract cities.
The FY 2023-24 LTF is 12%. All contract
cities pay the same rate.
City of Diamond Bar - 2023 Public Safety Annual Report | 16 The City’s FY 2023-24 contract law personnel deployment is as follows:
1 10 5 1
The City’s contract law rates are all-inclusive, meaning that the City is not charged for the complement of command, detective, and administrative staff including the Captain, Service Area Lieutenant, Detective Bureau, and other support personnel, facilities, equipment, or emergency deployments in response to an emergency or disaster.
The City’s patrol deputies are assigned to one of three shifts, with personnel levels ranging from three to eight deputies per shift. Personnel levels are adjusted by the station captain based on trends and operations and may be supplemented on any shift by additional personnel, including the Special Assignment Team.
The Special Assignment Team (made up of 40-Hour Deputy, No Relief positions) is a community policing program designed to provide maximum flexibility and responsiveness. In addition to conducting suppression patrols, traffic enforcement, and special investigations targeting specific crime trends, Special Assignment Team deputies work directly with residents, businesses, and schools to provide a consistent customer service presence from law enforcement. They also provide additional specialized traffic enforcement, lead Neighborhood Watch, represent the Department at public meetings and events, and handle community relations.
Volunteers on Patrol
Diamond Bar Volunteers on Patrol
(VOPs) play a key role in the City’s
public safety program, performing
non-hazardous duties such as
residential vacation checks, park
safety checks, traffic control
operations, and directed patrol
assignments. The City Council honors
Diamond Bar VOPs at an annual
holiday appreciation dinner.
Eighteen Diamond Bar VOPs provided 6,294 volunteer hours, providing over $200,149 in value to the community.

City of Diamond Bar - 2023 Public Safety Annual Report | 17 Crime Statistics Analysis
The following analysis is based on statistics provided by LASD for the 2023 calendar year.
Part I Crimes Defined
Part I crimes are reported in two categories: violent crime (homicide, rape, aggravated assault, and robbery) and property crime (burglary, larceny theft, grand theft auto, and arson). These standard classifications, collectively known as “index” crime, are reported to the FBI because the crimes are considered serious, tend to be reported more reliably than others, and are reported directly to local police versus another agency.

City of Diamond Bar - 2023 Public Safety Annual Report | 28 Traffic Statistics
Diamond Bar’s location in a region with over 20 million people presents inherent traffic management and enforcement challenges. Immediately adjacent to one of the most congested freeway interchanges in the nation, Diamond Bar’s arterial streets face a high volume of cut-through traffic and school zones are impacted by a high volume of out-of-district commuters during pick-up and drop-off periods. Large-scale residential development projects currently under construction in the Inland Empire will likely result in additional commuter traffic on local freeways.
The City’s traffic management infrastructure
(signal synchronization, traffic management
system, Neighborhood Traffic Management
System, etc.) is the first line of defense against
traffic congestion. Ongoing enforcement
efforts by the City’s law enforcement team
work to ensure that drivers travel safely,
reducing collisions and travel delays.
In addition to daily enforcement by the dedicated traffic enforcement car, patrol deputies on all shifts provide enforcement. Supplemental enforcement is provided by the Special Assignment Team on an as-needed basis, particularly in busy school zones. % Difference 19.6%

City of Diamond Bar - 2023 Public Safety Annual Report | 31 Crime Prevention, Outreach and Advocacy
In addition to daily patrols, the City uses a diverse array of supplemental techniques to prevent and reduce crime and develop partnerships in the community.
Special Operations
In addition to the funding of
regular law enforcement
personnel, the annual municipal
budget includes appropriations for
as-needed special operations
outside the scope of daily patrols.
Multiple special operations were
conducted in 2023, again focusing
on burglary suppression and DUI
enforcement.
Suppression operations included
expanded patrol units, undercover personnel and vehicles, and targeted surveillance, with allocated resources fully dedicated for the specific task.
Supplemental undercover operations are funded with additional City Council budget appropriations outside annual personnel contract costs.
Flock Safety Automatic License Plate Reader Cameras
At the City Council’s direction, 50 Flock Safety automated license plate reader (ALPR) cameras were deployed
throughout the city, primarily on arterial and collector streets at ingress and egress points. These cameras capture license plate data and vehicle make, model, color, and special
features like roof racks and/or stickers. This data is
searchable and is cross-checked with state vehicle
databases so that deputies in the field can receive real-time push notifications when a stolen vehicle or driver with an outstanding warrant passes by a camera. The data
collected by the cameras also serves as an investigative tool when supplemented by witness accounts.
City of Diamond Bar - 2023 Public Safety Annual Report | 32 Let’s Talk Public Safety Program
Created by the City in partnership with the Los Angeles County Sheriff’s Department and Los Angeles County Fire Department, the Let’s Talk Public Safety (LTPS) program is aimed at engaging with the community and raising awareness about everything public-safety related, from emergency preparedness to crime prevention.
Neighborhood Watch
The Diamond Bar Neighborhood Watch program is a partnership between the City’s Public Safety Team and the community. Led by Community Relations Deputy Aaron Scheller, Neighborhood Watch groups actively participate in preventing criminal activity before it starts and assist law enforcement in developing solutions to local issues.
Participants are called upon to reach out to their neighbors to organize groups united to prevent crime. Established groups become the additional “eyes and ears” necessary to keep their neighborhoods safe.
Neighborhood leaders, or “Block Captains” serve as the primary liaison between the neighborhood and law enforcement, distributing information and coordinating meetings. For security reasons, the identities and locations of Block Captains are not revealed to the public. Neighborhoods with active groups feature City-provided Neighborhood Watch signage.
Neighborhood Watch groups generally meet in the evenings or on weekends in a small group setting, usually hosted by the neighborhood Block Captain. The meetings feature an interactive presentation with the audio/visual capabilities of the City’s portable Neighborhood Watch trailer. Topics of discussion include, but are not limited to crime prevention and burglary suppression, home safety and security, emergency preparedness, reporting suspicious activity. There are approximately 100 known Neighborhood Watch groups.
Coffee with a Cop
“Coffee with a Cop” meetings are
held twice a month on Saturday
mornings. Each meeting offers
informal, conversational dialogue
with residents and deputies with
crime prevention tips and Q&A
opportunities.
