This document outlines a planning framework for evaluating policy ideas related to Sea-Tac Airport and surrounding communities. Each idea is scored on two factors — technical feasibility (Possibility of Application) and community acceptance (Acceptance Factor) — which are multiplied together to produce an Index of Implementation Probability ranging from 0 to 9. Ideas scoring 0 are eliminated from consideration, while higher-scoring ideas advance as viable planning alternatives to be combined and refined in a subsequent phase of the planning process.Open full document
Notes
This document introduces the program choices and idea weighting methodology used in the Sea-Tac Communities Plan (STCP) Phase II planning process. It explains how planning ideas are evaluated using three criteria: Possibility of Application, Acceptance Factor, and Index of Implementation Probability. Each criterion is scored on a 0-3 scale, and the product of the first two yields an implementation probability index used to determine whether an idea advances as a planning alternative.
