The seawater intrusion webpage has been reorganized for simplicity and clarity.  Many of the documents previously posted on this page continue to be accessible in the Process and Document Archive section below.

For questions about the information on this webpage or the County policies and regulations for protecting groundwater against seawater intrusion, contact the Department of Community Development.  For more information about well monitoring or the science of seawater intrusion, consult County Natural Resources.



Background

Seawater intrusion (or salt water intrusion) is the underground flow of salt water into wells and aquifers.  It occurs when fresh water is withdrawn faster than it can be recharged near a coastline.  Jefferson County Public Utility District (PUD) No. 1 offers a webpage answering “Frequently Asked Questions about Seawater Intrusion.”

Jefferson County has policies and development regulations intended to protect groundwater against the phenomenon of seawater intrusion.  Three types of Seawater Intrusion Protection Zones (SIPZ) have been designated as Critical Aquifer Recharge Areas (CARAs): Coastal SIPZ, At-Risk SIPZ, and High Risk SIPZ.  See the Maps and Map Key section below for depictions.  The level of regulatory protection is related to the type of designated SIPZ.

All residents, whether residing inside or outside a designated SIPZ, are encouraged to conserve water to help protect our water resources.

Policy and Regulations

Jefferson County has refined its policies and regulations for protecting groundwater against seawater intrusion from adoption of the initial “critical areas” ordinance in 1995, through adoption of the Comprehensive Plan in 1998 and the Unified Development Code (UDC) in 2000, to a growth management compliance process that was completed in early 2004.

For a chronological presentation of the process that lead to the current policies and regulations, refer to the Process and Document Archive section below.

The Board of County Commissioners (BOCC) adopted final policy language into the Comprehensive Plan on December 8, 2003 under case number MLA03-210.  The policy includes provisions for adaptive management of areas subject to groundwater degradation from seawater intrusion.  For more information on these legislative amendments, visit the 2003 Comprehensive Plan Amendment Cycle page.

Regulatory protections against seawater intrusion are codified at UDC section 3.6.5 Critical Aquifer Recharge Areas.  The code refers to a list of administrative water conservation measures, which are voluntary in most cases and mandatory in High Risk SIPZ.

Growth Management Compliance

After the County adopted the UDC in December 2000, a petition for review (PFR) was filed with the Western Washington Growth Management Hearings Board (WWGMHB) concerning whether groundwater protections against seawater intrusion were compliant with the Growth Management Act (GMA).

A lengthy compliance process has ended and case number 01-2-0015 is closed.  The WWGMHB issued a Compliance Order on March 29, 2004 that concludes that Jefferson County is in compliance with the GMA concerning protections against seawater intrusion.  The following documents are directly related to the compliance process, posted in chronological order beginning with the most recent.  Refer to Process and Document Archive below for additional documents.
