Mike Mahaffie, Delaware
• Three counties• 57 municipalities• 2,000 square miles• 885,000 people• One state government pays:
• 90% of roads• 60% – 80% school const.• 100 % school trans.• Most of police/EMS
• State Strategies for Policies and Spending• First version – 1999• Second – 2004• Third – Now
• Four “Investment Levels” and “Out of Play”

• This is the text box
• Every inch of the state accounted for
• Slivers and gaps and blivits edited away
• Polygons simplified and merged where appropriate
• Ready, when approved, to help guide state agency spending decisions• (If the legislators don’t
mind)
And local governments may, or may not, pay any attention
• The level of detail I’m allowed in the Document:• “…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
