Police

Law enforcement services to the village are provided by the Sea Ranch Lakes Police Department, which patrols the walled-in residential section of the village, the oceanfront beach club, and the shopping plaza within the village's municipal boundaries. The department has approximately 15 certified police officers and is led by Chief James O'Brien. Chief O'Brien retired from the Rochester NY Police Department as a captain and has over 40 years of law enforcement experience. Traditionally the department was staffed by former officers of the New York Police Department. Current members reflect officers from neighboring South Florida agencies as well as former state and federal law enforcement agencies. The department is dispatched by the Broward County Sheriff's Office 911 communications and responds as District 26. The department has six (6)patrol vehicles and a minimum of two sworn officers on duty at all times, with a normal weekday staffing of two officers, one police service aide, and the police chief.

The department prides itself on its low crime rate, with the majority offenses occurring within the commercial plaza. In the early 1980s, the department was one of the first in Broward County to have developed a formal hurricane emergency policy. Supplementing uniform patrol efforts, the department has detectives who are responsible for conducting most criminal investigations. The Sea Ranch Lakes Police Department has partnered with area law enforcement agencies through signed Memorandums of Understanding (M.O.U.) to address jurisdictional and/or resource issues that might be associated with any major occurrence.

The department provides all first responder services and assumes responsibility for such matters as Animal Control and residential security checks. The department renders "Mutual Aid Assistance" to other Law enforcement agencies operating primarily along the coast.

The department sadly has experienced the line of duty death of one of its patrol officers, Sergeant Henry Nelson Adams, in 1975. Sergeant Adams suffered a fatal heart attack while conducting a traffic stop, and died at the age of 50 after having served with the department for four years.^[14]

Fire and medical services

Fire and emergency medical services to Sea Ranch Lakes are provided by the Pompano Beach Fire Department. The village averages fewer than 100 calls for fire or medical services each year, with many being for services to the shopping plaza or residential fire alarms in the village. The village also averages less than one working structure fire per year. Throughout the history of the village, fire services have varied with each contract. Broward County Fire Rescue, the Lauderdale-by-the-Sea Volunteer Fire Department, and Fort Lauderdale Fire-Rescue have all provided fire suppression services to the village at some point.

The lowest bidder for fire services is usually awarded the four-year contract for services to the village. Before 1996, the Lauderdale-by-the-Sea Volunteer Fire Department served the town, with Fort Lauderdale Fire-Rescue serving until 2001. The Broward County Sheriff's Office Department of Fire Rescue & Emergency Services provided fire suppression services to the town from 2001 until 2008. As of October 2008, the Pompano Beach Fire Department provides services after Broward County Sheriff's Office closed its station in Lauderdale-by-the-Sea.

Utilities

Water services are provided to the town by the Fort Lauderdale Water Department. The residential section of the village has no sewer system, with each resident having an individual septic system. However, the shopping plaza is connected to the Pompano Beach sewer system. Power services are provided to the town by Florida Power & Light, with all residential power lines being buried underground. By having no utility poles inside the village, it is relatively easy to return power to the entire village following a storm, and is also aesthetically pleasing.

Public works

The employees of the Sea Ranch Lakes Beach Club are responsible for maintaining all of the villages lakes, parks, streets, and other property.
