4. Delineate the urban growth boundary. Factor desired development patterns, likely service areas and projected land requirements into drawing an urban growth boundary for your community. Determine how many acres of vacant land are needed to accommodate future population and growth.
During proliferation, the wound is ârebuiltâ with new granulation tissue which is comprised of collagen and extracellular matrix and into which a new network of blood vessels develop, a process known as âangiogenesisâ.
1 Platelet-derived growth factors are released into the wound that cause the migration and division of cells during the proliferative phase.  Proliferation (growth of new tissue): In this phase, angiogenesis, collagen deposition, granulation tissue formation, epithelialization, and wound contraction occur.
