GIS for Decision Support

1
GIS for Decision Support

• Efforts currently underway at the
  Rochester-Olmsted Planning Department

2
Attributes of the Ideal Decision Support GIS

• Clear, prompt feedback
• Intelligible and transparent to citizen boards
  reflecting their common sense perceptions
• Promptly modifiable readily tweakable
• Related to quantifiable goals
• Promoting continuous improvement

3
Example 1 Redistricting

• Clear, quantifiable goals
• Dont divide jurisdictions
• Concentrate minority voting areas
• Arrive at nearly equal districts
• Immediate feedback table with calculations is
  built in to extension
• Intelligible to lay people

4
Example 2 School Boundaries

• Clear, quantifiable goals
• Balance minority enrollment
• Balance enrollment with school capacity
• Avoid busing costs promote neighborhood schools
• Immediate feedback table with calculations is
  somewhat exportable to Excel
• Intelligible to lay people

5
Charge Statement Parameters

• Must take into consideration the school
  district's integration plan and comply with state
  laws should balance attendance by race and
  socio-economic status.
• Provide for equitable educational spaces for all
  necessary programs in each building.
• Strive for as much future placement stability as
  possible for students by considering the impact
  of projected population growth and development.
• Maximize efficient use of space, building staff
  and transportation resources.
• Strive to place all students in a building
  closest to their residence, especially for
  residences within the walking boundary of the
  school.
• Consider natural and man-made barriers when
  determining attendance boundaries.
• Promote contiguous attendance boundaries.
• Move as many students together from one building
  to the next, K-12.
• Provide a recommendation relative to whether
  students may voluntarily complete the last grade
  in the building currently attending prior to
  implementation of the boundary change.

6
Integration

• Must take into consideration the school
  district's integration plan and comply with state
  laws should balance attendance by race and
  socio-economic status (SES).
• range of enrollment percentages by race and SES
  in elementary, middle, high schools (range
  highest lowest)
• difference between majority students at all
  levels required to change schools and minority
  students required to change schools
• difference between high SES and low SES
  students required to change schools at all levels
• gap between ratios of enrollment by race and the
  allowable maximum or minimum

Integration Indicator Example

Equitable Spaces

• Provide for equitable educational spaces for all
  necessary programs in each building.
• Balance enrollment so that no school is over
  capacity.
• Minimize the range between highest ratio of
  enrollment to capacity and the lowest ratio see
  placement stability.

Example 3 CLUES Model

• Comprehensive Land Use Evaluation System
• Fair, efficient, sustainable land use
• Quantify land use policies so can be consistently
  applied across the county in a comparative
  fashion how suitable is a site compared to all
  others in the County?
• Use of ModelBuilder on laptop so can easily tweak
  in face of concerns raised by public, Planning
  Commission, County Board
