North Spanish Springs Floodplain Detention Facility

Following a 1986 Spanish Springs flood event, construction of flood control facilities in the unincorporated portion of Spanish Springs became a citizen-led initiative. Following several years of planning, flood control facilities were completed in 2008.

The facility captures and collects stormwater runoff generated in the Spanish Springs Valley, primarily from the Griffith Canyon area, and meters stormwater flows through the northern part of Spanish Springs through the City of Sparks, and ultimately to the Truckee River.

The total cost of the 2008 flood facility was $13.9 million of which $11.1 million was funded by two bond issuances. User rates and fees are charged to residents and business owners located within the Spanish Springs Stormwater Drainage and Flood Control Service Area. Due to a slow down in growth over the past several years, facility connection fees have not been realized. Therefore, customer rates are proposed to increase in order to insure the County's ability to cover its debt obligations for the project.

  • On April 24, 2015, the BCC adopted Ordinance No. 1552, amending sections of the previous Stormwater Drainage and Flood Control Service Ordinance, modifying the service area as well as the amount and basis for calculating stormwater management fees.
  • On April 14, 2015, the BCC held a public hearing for the second reading of proposed modifications to the existing Stormwater Drainage and Flood Control Service Ordinance No. 1537.
  • Following a Citizen Advisory Board meeting presentation in November 2014 and a public meeting on February 19, 2015, staff presented a Business Impact Statement to the Board of County Commissioners on March 24, 2015. 
  • At its February 25, 2014, meeting, the Board of County Commissioners (BCC) directed staff to modify stormwater management fees related to the North Spanish Springs Floodplain Detention Facility in order to fund a deficit in revenue required to pay operating expenses and debt service.
