About 500 elementary school students living in northeast Brentwood will attend the new Mary Casey Black Elementary School campus, which opens in July, after the Brentwood Union School District adjusted attendance boundaries this week.

Those kindergarten through fifth-grade students are now attending Brentwood, Garin and Marsh Creek elementary schools. All students residing in the new boundary created at Wednesday night's Brentwood school board meeting will automatically attend Mary Casey Black unless they obtain an intra-district transfer to their current school.

"We hope that people will be drawn to attend their neighborhood school," Brentwood assistant superintendent Margaret Kruse said.

The new boundary incorporates residences to the east of Brentwood Boulevard from Lone Tree Way on the north side to Oak and Chestnut streets along the south perimeter. Recent community meetings at the future campus near Sand Creek Road were well-attended by hundreds of parents and children, Kruse noted.

The deadline to submit an intra-district transfer form is March 1. By March 15, families who request a transfer should be notified of its status, according to district officials.

Eighteen teachers will be employed at Mary Casey Black, according to Kruse. She added that the school's debut will lower enrollment at neighboring schools, including Garin, which will go from about 870 students to 600 students in the next academic year.

"This school (Mary Casey Black) has the opportunity to grow," Brentwood Superintendent Merrill Grant said. "It has the capacity to go to 750 (students)."
