Officials: Misunderstanding leads to confusion over drainage district No. 2 funds Petronila drainage concerns and last updated 2021-01-12 21:39:34-05 Rural Nueces county residents are worried that a bond they approved in November won't be used for what it was intended. The concerns come from Nueces County's Drainage District No. 2, a body which serves the area around Petronila and Robstown. The problem, though, mostly sounds like a bit of a misunderstanding. Drainage District No. 2 residents have been waiting for a drainage solution for years, so when they heard the district was turning down a grant for something they approved, there was concern.
