plat rush
n.— «The notification that Prescott’s AMA was in a state of Groundwater Mining meant that the amount of water that can be taken out of the ground is capped. Period. But, in Prescott’s case it wasn’t immediate. The Prescott area was given some leeway in the timing of the cap being put in place. So, in 1998 developers rushed to get their plans for subdivisions approved before the rules went into effect. This is commonly called the “plat rush.”» —“Water 101″ by Helen Stephenson Prescott e-News (Arizona) . (source: Double-Tongued Dictionary)
