The plans will expand the exhibit hall and allow the center to have a greater range of events.
"It will make it more user friendly," said Parks, Recreation and Cultural Affairs Director Jeff Bowman.
The architectural firm of Greer Stafford/SJCF was awarded a contract to create the proposed plan.
If City Council approves the plan, it will go through a final phase of adjustment before bids for construction are advertised on Jan. 2, 2013.
"Hopefully there's not a lot of (adjustment)," Bowman said.
Among the renovations planned are new carpet, a new ceiling and walls with the aim of attracting a greater variety of events, including wedding receptions and banquets.
"We're converting this from a one-out gym into a beautiful ballroom," said City Manager Rob Mayes.
The plan converts the exhibit hall into a grand ballroom of about 7,924 square feet. This ballroom could be divided with folding partitions into three smaller ballrooms of 2,500; 2,290 and 2,495 square feet, respectively. The space can be further configured to five meeting rooms.
A new ceiling will be adorned by coffering, a design that uses sunken panels in the shape of squares, rectangles or octagons as a decorative effect. The design dates back to Ancient Rome.
Discussion in the community to renovate the Civic Center goes back at least 10 years, Mayes said.
In September 2011, City Council was presented with a plan to remodel the exhibit hall.
That plan also included proposals for the new regional animal shelter, museum expansion, Fire Station One and the Lakewood Detention Pond.
Council adopted the projects in early 2012 and funded them through a $9.1 million bond measure. The bonds used existing city debt from Fire Station Six and the Public Library, while continuing the same payment level by refinancing at a lower interest rate, Mayes said.
