The Patrol Unit is the backbone of the Lake Stevens Police Department.  

Patrol is divided into four squads to cover the city 24 hours a day / 7 days per week.  Each squad consists of a patrol sergeant who supervises highly trained patrol officers that are adept at responding to emergencies and other calls for service.  The patrol sergeant additionally supervises the day-to-day patrol operations. Patrol officers provide the initial response to calls from the public and are responsible for the prevention of crime, enforcement of laws, the arrest of criminals, and the protection of life and property.  Patrol officers are also trained to provide basic medical treatment to injured persons prior to the arrival of fire/medical personnel. All patrol officers have received crisis intervention training so that they can more effectively respond to those who are in a mental health crisis. 

Community Interaction

Patrol operates on the community-policing model in which input from the community is vital to determining policing strategies. Patrol officers often attend community meetings and events to interact with residents to assist in addressing their concerns regarding law enforcement. Patrol is responsible for traffic and crowd control at all the major parades and events in the city. Patrol officers also monitor our city parks and open areas to reduce the problems routinely encountered during the warmer months, with the goal to reduce the problems of disorderly conduct, criminal mischief, drug activity, and thefts, to make our parks safe for family activities throughout the year.


In addition, the Operations Division works hand in hand with our partners throughout the region.  The Operations Division assists our local partners with extra officers during major events and the sharing of information regarding offenders and crime trends in the area.  The Lake Stevens Police Department also has dedicated patrol officers who are members of the Snohomish County Regional SWAT Team and Violent Offenders Task Force.  These tasks forces are tasked with locating and taking into custody the most high-risk offenders.

Professional Excellence

The Lake Stevens Police Department made a commitment to the community to constantly review our training and procedures of how we respond to situations.  With this diligence and continuous improvement, our patrol supervisors and officers are some of the highest trained law enforcement professionals in the area.
