Santa Ana City Council members will vote Tuesday on the largest pay raises for the city’s police officers in more than a decade, totaling $25 million in taxpayer money over the next two and a half years and adding $12 million per year going forward in additional costs. The raises amount to a 13.6 percent to 19.3 percent increase in base pay for each officer and sergeant between now and July 2020, according to the city. Officers and sergeants with 15 to 19 years in law enforcement would receive raises totaling 16.5 percent, and those with 20 or more years would receive 19.3 percent in increases. Before the last set of raises in 2017, the median compensation for a Santa Ana officer totaled about $213,000 per year, including $111,000 in pay before overtime and $88,000 in benefits, according to city data published by Transparent California. The city staff report doesn’t offer an explanation for the raises, beyond saying they resulted from negotiations between the police officers’ union and City Council.
