At its January meeting, the Duval County School Board approved the proposed boundary establishment for high school "AAA" (Atlantic Coast High School) and proposed boundary changes for Sandalwood High School, Englewood High School, Duncan Fletcher High School, Samuel W. Wolfson High School, and Mandarin High School. The approved item included an amendment that directed the Superintendent to review the boundaries each year for five years and determine any changes that might need to be made.

Atlantic Coast High School is situated in an area that has experienced high growth for the past few years and will relieve overcrowding at surrounding schools: Sandalwood High School , Samuel W. Wolfson High School, Mandarin High School; and will involve reassignment of students to and from Englewood High School and to Duncan Fletcher High School. The school will open in August 2010 serving grades 9 -11 and will add 12th grade for the 2011-2012 school year. Rising 12th graders residing in the attendance areas of impacted schools will be given a Special Transfer Option in order to remain at their current school for their senior year. Siblings of rising 12th graders may apply for a Special Transfer Option assignment to remain at current school through the regular lottery process.

As a part of the process to determine boundaries, working group meetings were held on May 4, 2009, May 18, 2009, August 31, 2009, and November 3, 2009. The community meeting was held on September 15, 2009 and a public hearing was held on January 5, 2009. All meetings were held at Twin Lakes Academy Middle School from 6 p.m. to 8 p.m. Notification of the meetings was done by email to SAC members, DAC (District Advisory Council), PTA members, and prior ACE volunteers.
