I just found Walkscore, a tool that uses Google maps and data to calculate a walkability score for a street address. You need to put in a complete address, eg, 900 Travois Way, Moscow, Idaho and then it looks at the kinds of services around you and the distances and calculates a score.
Imagine if this were part of the process included in the SmartGrowth scorecard. Take a measurement from the center of the proposed development and score the walkability. (I went Googling for Idaho Smart Growth because I know their scorecard and found that the US EPA has a more extensive Smart Growth Scorecard site.)
The other day I pointed to Green Chain Stores and highlighted a quote about the problem driving to a green store and suggested a vision for greening Moscow. Add this tool to the list of thinking for that greener city. Probably need to fold in a more complex analysis for bike-ability -- distance is a little less important, but gradients matter and amenities along the way and at the destination (eg good paths and parking) matter.
