Comment: Do you actually think you need the city council to make a formal declaration in order to avoid an intersection or shopping area in the city? No, you don't need that. Just don't go there, simple solution. 
I have lived in Federal Way for many years. It has definitely changed over time. I see that the mayor and the city council are really trying to make a nice downtown core. I love the new park and I love seeing families out using it. I love seeing young people play basketball there. I love the walkability of the downtown shopping area. I love that we have a new arts facility. Do I love the crime and the drugs, no,  but this area has grown so significantly over the years, I feel like some crime is part of city living. 
If you feel you have so much expertise on city planning, why don't you run for city council and help your city with some suggestions for improvement.
