I think that you have chosen well your 5 Design principles for An Alternative master-plan for Meri Rastila.
I think you have found the right focal points in your list. In planning it is crucial to make use of the local knowledge. Much damage can be done, if the community is not heard.
The city planners tend to have an arrogant attitude that they know best what is good for the community. If they instead of looking at the white areas in the map took the time and trouble to find out what is out there in the real life and what is the spirit of the place, WIN-WIN solutions could be found.
These design principles make it easier to see that it is possible to tackle many challenges with the help of a well planned solution.
Not only were your design principles good. The plan of yours followed the principles.
I suspect that the city planners use the social segregation argument as an excuse for their plan because their real reasons for wanting to build in the forest do not sound as good. But even if it was not an excuse, I think they are wrong in their attitude towards the Meri-Rastila people. Social problems cannot be solved if the community is not included in the process.
A better approach would be to find solutions that help the people that already live here. If the problem is that some pupils do not have a good enough knowledge of Finnish then they should be taught the language, building houses in the forest does not help them. But as I see it, the children and young people of different origins already mix very well in this area, so as the generations move on the so called problem may solve itself.
One of the keypoints really is that if a solution does not help the people living in a certain area it can not be a solution for the problems of this very same area.
Another keypoint is that if a solution takes notice of both nature issues and segregation.it is a special kind of possibility.
Segregation is not a matter of statistics. We have to focus on the things that are most important in everyday live.
The principles are good. Especially it is important to respect the fine natural areas that Meri-Rastila has left. In every respect I can think of the forest adds the value of Meri-Rastila more than any kind of residental area in its place.
Reduction of segregation might also be looked at from the point of view of common space that is open for everyone. What if we could have in Meri-Rastila things like:
– recreational forest
– Haruspuisto with new kind of possibilities
– a new house near Haruspuisto for culture and different kind of common things
