  2. What is an Urban GrowthBoundary (UGB)? • Regional Boundary used to designate where growth is intended to take place • Inside the UGB: High density urban growth • Outside the UGB: Low density rural, agricultural, wilderness, or open space • Established by local, regional, or state government • In King County, established in 1995

  3. Why use an Urban Growth Boundary? • Efficient use of land • Maximize infrastructure investments • Water • Electric • Transportation • Preserve existing farmland or wilderness • Control growth / Prevent sprawl

  4. Strategies used in the analysis • Using Residential Building Permits, 1991 – 2002, database of housing types • Multi-Family(apartments, condos, ect.) • Single Family(classic suburban home) • Distinguishing which building permits fell within the UGB vs. building permits which fell outside of the UGB • GIS

  5. Strategies • Determining the number of housing units per building permit (for MF only) • Statistical analysis • One-sided T-test • Comparing levels of housing units, before and after UGB implementation

  6. Expected Results if the UGB is Successful • An increase in MF housing units • Especially inside the UGA • A decrease in SF housing units • Especially outside the UGA

  7. Results: Urban Growth Boundary Enacted

  11. Results • MF Housing Inside has Increased • MF Housing Outside has Increased • SF Housing Inside has Remained Steady • SF Housing Outside has Decreased

  12. Conclusions • The UGB has had an effect • There has been an increase in MF housing units • More substantially inside UGB • While SF Housing inside UGB remained constant, outside it has dropped substantially
