But It HARDLY RAINS here!
Stormwater management is about more than stormwater... (think streams and groundwater), more than runoff... (think water quality), and more than management... (think stewardship)!
Adopted in 2016, the City's first "Storm & Surface Water Master Plan" integrates these concepts and addresses the needs of 20 years of growth as well as changes in the climate and regulatory environment. (Click here or the link to left)
With the help of grant funding,* planners and engineers from Herrera Environmental evaluated the City's facilities and operations while addressing problem areas identified in the 2014 "Stormwater Management Needs Assessment" (Click link to left) and provided strategies for how to pay for the work needed. Currently, all stormwater work is funded by our Sewer and Water Utilities.
Also, because individuals make choices in their homes and workplaces which either prevent or cause water pollution, education and outreach is always a component of stormwater management work.
All sources of water are vital to our future... including stormwater!
*Major grant funding obtained from Washington Department of Ecology's Centennial Clean Water Program. Further information on the grant which ran from 2015-2017, click here or on the grant project link to the left.

As of 2017, the City's "Stormwater Stewardship" grant ended, and with it so did web updates and notifications. You can read and follow Ann Soule's monthly Sequim Gazette "Water Matters" column at www.WaterColumnSite.wordpress.com. Blog entries are local to Sequim-Dungeness and cover water quality, climate change, water supplies, and more.
