Stormwater & Watershed Quality Management


Storm Water


The water that is produced by natural precipitation such as snow, sleet, and rain. As this water accumulates it begins to move and migrate through a process known as runoff. Storm Water Runoff moves through our environment picking up items along the way. These items can include plastic bottles, wood, sediment, and petroleum products to name a few. A Watershed is a topographical surface feature on our Planet Earth where rainfall and precipitation drain to a common location.

Storm Water Management Plan

The City of Grapevine has developed a Storm Water Management Plan (SWMP) per the Texas Commission of Environmental Quality's (TCEQ) General Permit to Discharge Under the Texas Pollutant Discharge Elimination System (TPDES) - Stormwater Discharges from Phase II (Small) Municipal Separate Storm System Sewer System (MS4s) TXR040000.  The Current Permit was issued on January 24th, 2019 and is a 5-year permit.  The City of Grapevine holds Permit Number TXR040114.  This permit allows the City to discharge unpolluted waters to Water of the United States.  The purpose of the SWMP is to provide a guidance document for the City to reduce and/or eliminate potential storm water pollution sources before those pollutants enter the Waters of the U.S.

The current 2019 MS4 Permit and FAQ provided guidance for the development of the City's SWMP.

The current Notice of Intent and SWMP (2019) for the City of Grapevine are available online and for review in the City's Library (1201 Municipal Way).

The Annual Reports submitted to the TCEQ for the fiscal years 2019, 2020, 2021, 2022, and 2023 (to be submitted to the TCEQ 12/2023) can be found here.

Management of storm water resources is governed by the Clean Water Act under the National Pollutant Discharge Elimination System. The City of Grapevine’s goal is to work in a cooperative teamwork spirit with the Texas Commission on Environmental Quality, the United States Environmental Protection Agency www.epa.gov, the North Central Texas Council of Governments, as well as all county and local governments to manage storm water quality concerns as effectively as possible.
