Superintendent's Preliminary
Recommendation
Analysis of Proposed
Building or Program Closure, Consolidation or Relocation School
Closure Decision-Making Model
In developing the Superintendent's preliminary recommendations,
District staff used a three-step process to identify schools and
programs.
First, the district was divided into six "planning regions" as
follows:
- Northwest: North of the ship canal, west of
I-5
- Northeast: North of the ship canal, east of
I05
- Queen Anne/Magnolia
- Central: South of the ship canal, north of
I-90
- South: South of I-90, east of
Duwamish/I-5
- Southwest: West Seattle
The excess or shortfall of capacity was calculated for each
region and grade level (elementary, middle, and high) to determine
the number of possible building closures or school
consolidations.
Second, the schools within each region were compared with each
other using a set of objective criteria previously proposed to the
school board. These criteria are as follows:
- Building Capacity: The number of students a
building can hold; this is also referred to as its "planning
capacity." To calculate each building's capacity, we multiplied the
number of teaching stations, or classrooms, by the appropriate
standard class sizes:
- Kindergarten - 3rd grade: 23 students
- 4th - 5th grade: 25 students
- 6th - 8th grade: 28 students
- 9th - 12th grade: 30 students
Then we subtracted 25% to account for space needed for some
Special Education classes, six periods at high schools, special
program resource rooms, community use, etc. All open school
buildings were included and categorized according to their original
design use (i.e. elementary, middle, or high). Capacity in
portables was also included.
Buildings with larger capacities are preferred .
Buildings with larger capacities allow for more flexibility in
program placement as well as possible future increases in student
enrollment.
- Portable Score: The percent of a building's
capacity not in portables. The portable score ranges from 0 (all
capacity is in portables) to 1.0 (all capacity is in main
building). This is calculated as the current planning capacity not
in portables divided by the building's total planning capacity
(including portables).
Buildings with more capacity outside of portables are
preferred . While portables are often necessary, we prefer to
have more students housed within a school's main building.
- Site Size: The size of a school's property,
measured in acres. The site size only includes the portion owned by
Seattle Public Schools. According to the Seattle School District
Facilities Master Plan (adopted March 17, 1999), the site size
goals for school buildings are:
- Elementary: minimum of 4 acres
- Middle: minimum of 12 acres
- High: minimum of 17 acres
Buildings with larger site sizes are preferred .
Schools with large sites allow for more flexibility to expand the
building through remodeling or rebuilding, or to place portables if
needed.
- Building Condition: The physical condition of
a school building. Each building's condition is measured by its
Study and Survey Building Condition Evaluation Form score, which
ranges from 0 to 100. School districts in Washington State are
required to submit a comprehensive report regarding school
facilities titled "Study and Survey" which is used in determining
the state match portion for school construction. The last Study and
Survey was completed May 31, 2002 by MENG analysis, Educational
Facilities Consultants. The Study and Survey includes an inventory
of the District's school facilities and evaluation of their
educational and physical conditions and an overview of current
capital improvements. Each building is given a score based on "100"
being perfect.
Buildings in better condition are preferred . Buildings
in better condition are safer, more comfortable, and provide better
learning environments for students.
- Isolation Score: A measure of a building's
relationship between its planning capacity, the underlying Seattle
Public Schools resident enrollment (2014 projection), and the
planning capacity of adjacent buildings. The isolation scores range
from 0 (complete overlap with surrounding buildings) to 1.0 (no
overlap). The isolation scores are calculated by first creating
fictional "attendance areas" around each elementary school that
include enough resident students to fill the building, using the
projected number of Seattle Public Schools students living in the
surrounding block groups and the building's planning capacity. If a
school's "attendance area" overlaps with that of one or more other
schools in the area, the number of students not contained in the
overlapping area(s) is divided by the total planning capacity to
create the isolation score. The overlap occurs when the resident
population can be served by multiple buildings, which indicates
either a small resident population, a high density of buildings, or
a combination of both.
Buildings with higher isolation scores are preferred .
Buildings in densely populated areas are needed to provide enough
capacity for neighborhood students. In addition, geographically
isolated buildings can help provide students with schools closer to
their homes and reduce transportation costs.
- Walk Score: The proportion of students who
could walk to a school. Walk scores range from 0 (no students live
within the walk zone) to 1.0 (building can be filled with students
who live within the walk zone). These are calculated as the number
of current Seattle Public Schools students (attending any school)
who live within the designated walk zone of a school, divided by
the school's building capacity. Walk zones around schools are
generally as follows:
- Elementary schools: 1 mile
- Middle schools: 2 miles
- High schools: 2.5 miles
Buildings with potentially more students walking to schools
are preferred . A higher percentage of students walking to
school may provide the opportunity for lower transportation
costs.
- First Choices: The number of students who
listed a school as their first choice on their application. This is
an indicator of the popularity of a school.
More popular schools are preferred . High numbers of
first choices indicate perceived quality of a school; we hope to
minimize disruption to popular programs.
Schools received a score for each criterion, and then the
schools within each region were ranked on each criterion in
descending order. No weights were applied to the criteria,
but in some cases criteria were eventually weighted differently
depending on the unique circumstances within each region.
Then the sum of each school's rankings was totaled and those totals
were ranked to produce an overall ranking across all seven criteria
for each building within the regions.
Third, starting with the lowest overall ranking buildings in
each region, staff discussed the issues, concerns, or challenges
associated with closing or consolidating the identified schools or
programs. Board and community input were considered as well
as the four goals of the plan. While the rankings were used
as a starting point for the discussion, in some regions the schools
recommended for closure were not originally the lowest ranking
schools.
