Planning Commissioners Sam Clark and Steve Mensinger, who had previously announced their interest, also applied.
In addition to his application, Clark, a former council candidate, submitted a letter highlighting his time and service in the city since moving to Costa Mesa in 1986.
"I bring a discerning mind and a skill at finding the middle ground," he wrote. "I believe there is a right answer if we can persist in finding it. One that meets the needs of all the citizens we serve."
Parks Commissioner Jeff Mathews attached to his application a detailed overview of the issues facing the city, as well as his experience and education, including a law degree, to help solve those problems.
In June, Mathews was elected to the Orange County Republican Party Central Committee, serving the 68th Assembly District.
"I was elected with over 11,000 votes — the fifth-highest out of the 13 candidate running (for six open seats)," he wrote in his letter. "Many of those votes were from residents of Costa Mesa that believed in my message of low taxes, limited government and fiscal responsibility. I pledge to remain true to those beliefs, and as a council member for our city, I will pledge to adhere to these principles in all facets of my service."
Former Costa Mesa Councilwoman Heather Somers is also among the candidates interested in the two-year appointment position.
"I feel I have the knowledge, skills accomplishments to serve the city through a very difficult period," Somers wrote in her application.
Somers said her past experience on the council qualify her to serve again.
Former City Council candidate and Westside resident Chris McEvoy's application was short and to the point. He was the third-highest vote-getter in the Nov. 2 election.
