Urban and regional planning firm established 1979 in Portland, Oregon.

Specialization measuring land-use and transportation performance of communities and their plans to inform and compare options.

INDEX planning support software:– Assess community conditions.– Design future scenarios.– Measure scenarios with performance indicators.– Rank scenarios according to goal achievements.– Monitor implementation of adopted plans.
