framework encourage or restrict the design, and
what changes would help implement it?

Method

• Site analysis conducted by biologists from the
  Universite de Moncton and NBCC Moncton

• compact living
• Community Resource Inventory
• Primary/secondary conservation areas
• Potentially developable area
• Different density options gross versus net
• Flexible applications continuum of encouragement

How to make SCD possible, cont

• Zoning by-law
• New mixed use zone could allow developer option
  of SCD
