- 1. Using Spatial Analysis to Develop a Comprehensive Statewide Land Use PlanMike Mahaffie, Delaware
- 6. One state government pays:
- 7. 90% of roads
- 8. 60% – 80% school const.
- 9. 100 % school trans.
- 11. First version – 1999
- 12. Second – 2004
- 13. Third – Now
- 14. Four “Investment Levels” and “Out of Play”
- 15. Generally match municipalities/traditional growth patternsYes, it is a golf reference
- 22. Police, Fire and EMS coverage
- 24. Hospitals
- 28. Corridor capacity preservation areas
- 29. The Delaware Coastal Zone
- 30. Wetlands (plus a buffer)

- 53. (If the legislators don’t mind)And local governments may, or may not, pay any attention
- 55. “…created using a spatial data analysis that balances state, county and local policies that favor growth for different areas of the state with policies that favor land preservation, agricultural economic development, and natural resource management.”Maybe I should sit down now

- We’re a small state, and the state government pays for most things. So we need to have a coordinated approach to growth and development.
- The idea is to combine all state and local policies relating to land use management into one comprehensive picture and use that to guide state spending decisions that tend to enable and guide new development.
- Levels 1, 2 and 3 are where we generally want growth to go. Level four, not so much.
- First we combine in spatial analyst every factor we can think of that argues for development. Using a 30-meter statewide grid. We give each a factor of 1 and add them all up.
- Then we do the same with factors that do not favor growth. Each of these gets a factor of negative 1
- The raw, combined data set has a score for between 20 and negative 11. It matches the cities and towns, and growth areas, pretty well.
- A little trial and error is needed to find the right classification system to approximate past versions. Then that is made into polygons for further editing.
- First we create the “Out of Play” by clipping out lands that simply can’t be built on.
- Then we let the people and the elected people mark the thing up to guide our further editing
- We found some odd effects that had to be cleaned up. Public lands tended to outline stream corridors, for example.
- That led us to look at other open water areas and do some cartographic editing…
- But we have finished and created a single, statewide data set of how we’d like to see development take place
- And now it’s in the hands of the policy people. With all that work very briefly summed up.
