Suitability Analysis

This chapter is mainly intended to suggest a springboard for filling gaps between analysis (method) and practices. Based on the result of suitability analyses under Scenario 1, ‘Equal Consideration,’ which places equal weight on the six criteria, this chapter tries to show how the four selected GI practices –rain gardens, bioswales, green roofs, and permeable pavement– can be located suitably, balancing the effectiveness of and demands for GI. The reason why the first scenario was selected for the suggestion is that since the other three issues are basically grounded on uncertain and unpredictable factors such as urban growth and climate change.
The recommendation provides possible ways to benefit from GI, balancing the effectiveness and

A series of maps (Figure 7) describe several sociocultural contexts including bicycle lanes, tree canopy, historical assets, social spots, and others. These maps do not represent all contexts of PPCOD, but can be importantly referenced for deciding the actual locations of the GI practices. For example,
• Bioswales are better placed along pedestrian streets or bike lanes rather than usual Right-of-Ways for providing closer user-oriented experiences.
• Existing parking lots shown as high suitability can be considered the best locations for permeable pavement.
• Rain gardens can be adjacent to or included in social spots, such as plazas.
• Buildings which provide social functions, such as new apartments (private community) or commercials, can be best suited for Roof gardens.
Foremost, however, it should be reminded that the suggested implementation was fundamentally grounded on the result of suitability analysis to satisfy demands for and increase efficiency of GI Figure 39 is a planning recommendation, created with integrated consideration of the contexts shown in Figure 37 and the result of suitability analysis, for the four selected GI practices to be located suitably. 10th Avenue and 11th Avenue are suggested as a main GI corridor where all the selected GI practices can be implemented along the avenues and where the two major public spaces –Cal Anderson Park and Seattle University– can be linked. Most of spaces in both avenues are
