Council Approves Surface Water Management Consolidation Ordinance
Snohomish County Council has approved a plan to restructure the county's surface water management utility from three separate districts into one. The reforms in Ordinance 17-020 will cut administrative costs, improve accountability, and provide better service to the public. The changes will go into effect July 21, 2017.
Until now, Snohomish County Surface Water Management (SWM) has operated as three separate utilities—South County, Snohomish, and the Stillaguamish River Clean Water District—even though people pay the same rates and expect the same services countywide. This previous utility structure created a wasteful administrative bureaucracy that was obsolete and inefficient, wasting resources and taxpayer dollars.
This new ordinance eliminates hundreds of thousands of dollars of administrative overhead, allowing more money to be invested directly in public services. It also improves transparency and accountability by requiring new annual reporting to Council and the public. A successful small grants program, previously only found in the Stillaguamish River Clean Water District, will be expanded into a countywide program open to all ratepayers under this plan. Utility rates will not increase under the new structure, and the Council will evaluate the system again in three years to ensure that projects and services are fairly distributed throughout the county.
