Microsoft Outlook Outage

Microsoft is currently experiencing an Outlook outage preventing City of Sammamish personnel from sending or receiving emails so there may be a delay in email responses. 9-1-1 is still fully operational for emergencies. For non-emergencies, you can report issues through MySammamish or you can contact the City by phone.

Stormwater Management Program

The NPDES Phase II Municipal Stormwater Permit, issued by the Department of Ecology, requires all regulated jurisdictions, including Sammamish, to update their Stormwater Management Program (SWMP) and submit an annual report.

The City’s SWMP Plan describes the city’s existing stormwater programs and outlines plans to update and modify these programs as necessary to meet future permit requirements. The City’s 2025 Annual Report was also completed recently and submitted to the Department of Ecology.

Both documents are available for public review and comment on the city’s Stormwater webpage.
