BAY POINT -- With too many students and too few desks at Delta View Elementary School in Pittsburg, new borders are being proposed for the upcoming school year.

Under the proposal, which must still be approved by school district trustees, students who live north of Highway 4 and along Marin Avenue and points farther east would go to Bel Air Elementary in Bay Point, while those who live north of Highway 4 and along Enes Avenue and points farther west would attend Rio Vista Elementary in Bay Point.

Although Delta View is in Pittsburg, it is part of Mount Diablo Unified School District.

Existing students who live in the impacted area north of Highway 4 and already attend Delta View, however, could be grandfathered in and not have to make the change.

Superintendent Steven Lawrence outlined the proposed boundary changes at a meeting Wednesday night at Riverview Middle School in Bay Point that was attended by more than 75 parents.

Before it can become a reality, the proposal must first go to a committee overseeing a master planning process for Bay Point schools. The committee, which will consider whether existing students in the impacted area can be grandfathered in, will make a recommendation on the proposal. The recommendation will then be presented as an information item at the district's April 22 board of trustees meeting before it is taken up an as action item at the May 6 meeting.

Increased residential development on the south side of Highway 4 has fueled the increased student population at Delta View over the years.

Delta View, which opened in 2004, has a capacity for 829 K-5 students. Currently, 67 additional students, mostly in kindergarten and the first and second grades who live within the school borders, are being sent to other elementary schools within the Mount Diablo district. Over the next 10 years, it's expected that the K-5 school population for Delta View and the three Bay Point elementary schools -- Bel Air, Rio Vista and Shore Acres -- is going to increase by more than 900 students, with most of the growth expected to occur at Delta View, according to a study that was done for the district.

The proposal didn't sit well with Gerrardo Valencia, whose son attends kindergarten at Delta View.

"It's not that we're afraid to go to other schools," he said, adding that the issue is about providing stability by staying in the same school. "My son right now is at Delta View and has more than 14 friends. I don't want him to go to another school."

Other parents said they would like to see a new school built near Delta View to handle the growth of students in the coming years.

"As a taxpayer living in Oak Hills, we need to build more schools," said Stacy Chester, a Pittsburg resident.

Lawrence said funding is not available to build a new elementary school, which is why the district is considering changing the boundaries for Delta View.

Adding portable classrooms to Delta View is not an option because of a lack of space at the school site.

"They didn't leave a lot of expandable room," he said.
