What is meant by a "larger common plan of development or sale?"
A "larger common plan of development or sale” is a contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under 1 plan. For example, if a developer buys a 20-acre lot and builds roads, installs pipes, and runs electricity with the intention of constructing homes or other structures sometime in the future, this is considered a common plan of development or sale. If the land is parceled off or sold, and construction occurs on plots that are less than 1 acre by separate, independent builders, this activity would still be subject to stormwater permitting requirements if the smaller plots were included on the original site plan.
