Incremental Build

One small step at a time, with 6 incremental builds over 13 years, this private institution has added a field, bleacher seating, press box, a sound system, a retaining wall more, bleachers seating… and now all of a sudden have a full blown stadium to which they want to add stadium light towers, a new sound system so that they can open their gates and pack our quiet streets with nightly crowds, late night noise, and heavy traffic.
This piecemeal approach, building projects incrementally can provide an effective way to avoid a review of the overall impacts of a project.  Would an incremental build (intentional or not) be considered a direct violation of both Washington’s State Environmental Policy Act (SEPA) and Seattle’s development provisions?
