Along with a sufficiently thorough discussion of anything comes the inevitable discovery of its strengths and weaknesses. The Portland Plan has a number of strengths: it is comprehensive, well thought out, inclusive, and should ultimately lead to a well-planned and sustainable city. How thorough the Portland Plan is is a testament to its preparedness to meet any challenges in leading the Portland of today to become the Portland of tomorrow, as any potential questions that may arise will likely be addressed within the text of the plan. The changing nature of the plan is to its advantage, as anything not addressed in the text of the plan does not make the plan obsolete, but rather can simply be found by finding the popular opinion of Portland's citizens, as the plan is simply an extension of the will of the people of Portland, and therefore the plan continually changes just as their needs and goals change. Furthermore, this plan will succeed where others have failed because the measures of success within the Portland Plan are overall quantifiable, and so both citizens and public employees can actively monitor cities' progress in accordance with the plan. Finally, the strength of this plan lies in its most singular aspect: the underlying theme of citizen participation. This is where the effectiveness lies, as it becomes a plan that does not simply force people to be sustainable, as so many have attempted to do in the past, but rather a plan that gives the people of Portland a support structure through which to educate people of Portland on these issues and provides them with an outlet that encourages the development of long-term sustainable behaviors and lifestyles. These strengths will allow Portland, Oregon... to be middle of paper... structure."
