Grand Prairie Certified iSWM Silver

The City of Grand Prairie was awarded the silver iSWM designation in December 2016! On January 10th, 2017, the North Central Texas Council of Governments presented the Grand Prairie city council with a plaque and street sign designating their iSWM status.

Some of the iSWM outcomes the City of Grand Prairie has focused on and implemented include:

  • incorporating hydrologic methods to properly determine the design of drainage facilities,
  • requiring a preliminary drainage study of proposed development sites,
  • and designing the drainage capacities of street and gutters to manage the flow of water.

Congratulations Grand Prairie for all the great work you are doing to improve the design of stormwater systems, control excessive runoff, and mitigate flooding!
