Pasco's Phase II Eastern Washington Municipal Stormwater Permit (Permit) runs from August 1, 2014 through July 31, 2019.  Per the requirements set forth in Permit, Pasco is required to develop and adopt a Stormwater Management Program Plan (Plan) that details all aspects of the City's Stormwater Management Program.  Click here if you would like to view the Plan.

The Plan evaluates the effect of the City's current stormwater utility structure, land use regulations and policies, and existing infrastructure maintenance with regard to risk management, environmental stewardship, and regulatory compliance.  The Plan sets near and long term planning goals and prioritizes a list of needed capital improvement projects to correct existing deficiencies within the system and to construct future stormwater mitigation infrastructure.

Joy Michaud, a Principal with Herrera Environmental Consultants, will share the major conclusions and implications of 2016 Stormwater Comprehensive Plan as part of the presentation to Council.

  
                                   DISCUSSION CONCERNING THE ADOPTION OF THE 2016 COMPREHENSIVE STORMWATER MANAGEMENT PLAN 
                                                                    WILL OCCUR AT THE MARCH 27, 2017 CITY COUNCIL WORKSHOP MEETING.
                                         FINAL APPROVAL OF THE PLAN IS SCHEDULED FOR THE APRIL 3, 2017 CITY COUNCIL REGULAR MEETING.


Rain and snowmelt that collects on impervious surfaces like roofs, roads and parking areas, becomes stormwater runoff. Runoff that reaches our rivers or infiltrates into our groundwater often carries harmful pollutants. Heavy metals, lawn and garden chemicals, animal waste, sediment, petroleum products, and trash are common pollutants found in stormwater. In fact, urban runoff is responsible for more than 60% of the water pollution in Washington State! 
 
Even though Pasco only receives an average of 8 inches of rainfall annually, the pollutant load here can actually be even greater than in cities that receive much more rainfall. That's because the pollutants have a longer time to collect and concentrate on impervious surfaces between our infrequent storm events.

To ensure the health and safety of our citizens and our rivers, the City of Pasco operates a Municipal Separate Storm Sewer System (MS4) under a Phase II Eastern Washington Stormwater Permit (Permit) issued by the state of Washington. The City created a Stormwater Management Program (SWMP) to comply with the requirements of the Permit. The City's annual report documents the steps we've taken to comply with the conditions of the Permit.

The good news is that we can all do something to help to keep our stormwater clean

If you are having problems with road drainage, blocked storm drains, property or basement flooding, or to report illicit discharges to the City's stormwater system please call the STORMWATER HOTLINE at 509-543-5777
