Seattle City Parks Metal Detecting Ban and Restrictions
Seattle Municipal Code 18.12.070 prohibits removing, destroying, mutilating, or defacing any park property, including structures, monuments, vegetation, and infrastructure systems.
As of May 2017, Seattle officially banned metal detecting in city parks after detectorists left open holes and damaged irrigation systems.
You can’t dig in turf or vegetated areas under any circumstances. Tool restrictions limit you to hand tools with blades no wider than two inches—shovels are prohibited.
Illegal digging violations extend to removing sand, soil, sod, or any materials without authorization from the Department of Parks and Recreation.
You may scan loose sand at certain beaches like Golden Gardens if you don’t dig or remove anything.
However, enforcement remains active, and only authorized employees or permitted individuals may extract materials from park grounds. Park officials may interpret violations based on the extent of disturbance or damage caused to park features. While no specific law references metal detecting directly in the code, authorities rely on general language about damage and vandalism to justify the restrictions.
Washington State Parks Metal Detecting Opportunities
You must register with Washington State Parks before conducting metal detecting activities at any state-operated facility. Registration is available online through the official form at parks.state.wa.us, where you can also download the color registration brochure and access the guide “Your Guide to Metal Detecting in Washington State Parks.”
Metal detecting is permitted in designated areas at more than 67 state parks throughout Washington, with specific locations determined by the director’s designee and posted for public reference at each facility. Activities are restricted to posted daylight hours, and metal detecting is not permitted during seasonal or emergency closures unless otherwise authorized.
Maps of parks are available on the Washington State Parks website to help you identify permitted metal detecting locations and plan your treasure hunting activities.

Permitted Detection Locations
Under current Washington State Parks regulations, metal detecting is permitted in more than 67 designated locations throughout the state park system. You’ll find these approved zones through geospatial mapping layers available on the parks website after registration. Grey-shaded areas on official maps indicate where you’re authorized to conduct detection activities.
Approximately 30 state parks currently allow metal detecting with proper registration. You can access these opportunities in your occupied campsite and unoccupied campsites within approved campgrounds.
The parks department determines designated areas through an algorithmic process that balances recreational access with resource protection. The geospatial data is available in ArcGIS FeatureLayer format for use with compatible GIS applications and web services.
Detection training proves valuable when evaluating mineral authenticity of discovered items. Remember that federal ARPA regulations prohibit removing objects exceeding 100 years old.
You must comply with posted regulations and consult “Your Guide to Metal Detecting in Washington State Parks” before beginning activities. When arriving at a state park, you must present printed coupons to rangers along with the current date and your party size.
Registration Process and Required Permits
Before you begin metal detecting in Washington State Parks, you must complete the mandatory registration process available at parks.state.wa.us.
You’ll need to download and review the color registration brochure from the parks department website to understand compliance requirements.
For additional guidance or questions about documentation, contact park rangers directly or call (360) 902-8500 to obtain “Your Guide to Metal Detecting in Washington State Parks.”
If you discover items during your metal detecting activities, ensure you maintain accurate transaction records and proper documentation, as businesses dealing with found goods must comply with regulatory standards. For additional guidance or questions about documentation, contact park rangers directly or call (360) 902-8500 to obtain “Your Guide to Metal Detecting in Washington State Parks.”
When detecting on private property, always secure explicit landowner permission before beginning your search to avoid potential legal complications.
Washington State Parks Registration
Metal detector operators must complete a mandatory registration process before conducting any detection activities within Washington State Parks. This requirement applies across 67+ designated parks and carries no fee as of 2022.
You’ll notify park personnel at your intended location, demonstrating compliance with land management protocols. Failure to register constitutes a violation under RCW 7.84.
Post-registration, you’re restricted to designated areas as posted, including your occupied campsite and unoccupied sites within approved campgrounds. Operations occur during daylight hours only, respecting seasonal closures.
You must dispose of all discovered trash, maintain silent detector operation, and avoid interfering with other visitors.
Historic sites require separate DAHP permits, while private land access demands landowner authorization beyond state park boundaries.
Online Registration System Details
Washington State Parks provides an online registration system through its FormCenter platform at http://parks.state.wa.us/FormCenter/Miscellaneous-12/Metal-detecting-form-76. You’ll complete this mandatory registration before detecting in any of the 67+ permitted state parks. Your registration remains valid for one year and grants you access to designated areas where you can search for historical artifacts within legal boundaries.
Note that archaeological permissions require separate authorization under WAC 352-32-235.
Key Registration Requirements:
- Review 55 downloadable maps showing algorithm-determined open areas before submitting your registration.
- Obtain the color brochure at http://parks.state.wa.us/DocumentCenter/View/929 for complete guidelines.
- Contact rangers at (360) 902-8500 for clarification on specific park regulations.
- Verify current rules at http://parks.state.wa.us/127/Metal-Detecting, as policies update regularly.
Required Contact and Documentation
To legally metal detect in Washington State Parks, you’ll need to complete the mandatory registration process and maintain proper documentation throughout your activities. Contact park rangers at (360) 902-8500 to obtain the registration guide and current rules.
The system uses an algorithm for calculating permits and determining which areas remain open for detecting. You must review “Your Guide to Metal Detecting in Washington State Parks” before beginning.
Tool restrictions apply strictly: hand tools only, with blade widths limited to 2 inches maximum. Shovels are prohibited in Seattle City Parks.
For archaeological or historical artifact searches, you’ll need a special use permit. When prospecting, file a Notice of Intent under 36 CFR 228 A and verify mineral claims through County and BLM records beforehand.
Nearby Cities and County-Level Regulations

Beyond Seattle’s city limits, neighboring jurisdictions maintain distinct metal detecting regulations that require careful attention before you venture out. King County requires permits for park detecting, while Snohomish County restricts hobbyists to beach areas only—turf zones remain off-limits. Renton prohibits detecting in city parks entirely but permits school ground exploration. Enumclaw allows detecting except at Mud Mountain Dam Park, with hand tool blade widths limited to two inches.
Critical compliance factors:
- Verify park-specific rules at individual sites, as metal detecting myths about universal permissions don’t reflect actual regulations.
- Review park safety guidelines posted on signboards before beginning any search activity.
- Obtain landowner permission for private property detecting, as federal ARPA restrictions protect historical artifacts.
- Contact respective parks departments directly—enforcement varies despite written policies.
County-level registration isn’t universally required, unlike state park regulations.
Approved Tools and Detection Techniques
While Seattle maintains no specific regulations governing metal detector specifications, selecting appropriate equipment directly impacts both detection success and site preservation compliance.
You’ll find handheld detectors like the ACE 250 with adjustable sensitivity settings and discrimination features provide ideal control for urban environments. Walk-through systems aren’t applicable for recreational detecting.
Your extraction toolkit should include serrated edge diggers constructed from heat-treated carbon steel and lightweight alternatives for precision work. Electronic pinpoint mode enables accurate target location before excavation, minimizing soil disturbance.
Detector maintenance requires regular cleaning and battery replacement—rental options starting at $36.00 daily include operational batteries. Proper gear transportation using protective sheaths preserves equipment functionality.
Target identification features with tone ID systems help you distinguish valuable finds from refuse, supporting efficient recovery operations while respecting park conditions.
Official Resources and Contact Details

Understanding Seattle’s metal detecting regulations requires direct consultation with municipal authorities who administer and interpret park codes.
You’ll find extensive information through the Seattle Parks Department‘s official website at seattle.gov/parks, which details Chapter 18.12 restrictions.
Email the department directly for specific inquiries about detection activities and site-specific permissions.
While no recreational permits exist for metal detecting, you must comply with SMC 18.12.070 regarding material removal and property preservation.
Essential Resources:
- Review Seattle Municipal Code 18.12.070 on official code publishing platforms for complete regulatory text.
- Contact Parks Department before detecting to confirm site-specific restrictions and sensitive area boundaries.
- Report historical artifacts of cultural or archaeological significance to appropriate authorities.
- Secure written permission from owners before detecting on private property adjacent to public parks.
Frequently Asked Questions
Can I Metal Detect on Seattle Beaches or Waterfront Areas?
You can metal detect on Seattle beaches, as there’s no explicit prohibition under beachcombing regulations. However, you must verify waterfront access restrictions with Seattle Parks and avoid archaeological sites. Always respect posted rules and swimming area perimeters for lawful detecting.
What Penalties Exist for Illegal Metal Detecting in Seattle Parks?
You’ll face legal consequences including fines up to $500 and potential one-day imprisonment for illegal metal detecting in Seattle parks. These penalty zones encompass all park properties where you’ve disturbed soil, damaged irrigation systems, or removed materials without authorization.
Are Private Property Owners Allowed to Metal Detect Their Own Land?
You’re free to metal detect your own land. Private landownership grants you autonomy over detecting permissions on your property. No federal or Washington state laws prohibit owner-conducted detecting, though you should report significant historical finds ethically.
Does Metal Detecting Require Liability Insurance in Washington State?
No, you’re not required to carry liability insurance for recreational metal detecting in Washington State. However, insurance requirements apply if you’re conducting organized special events needing permits, which mandate $1,000,000 liability coverage minimums.
Can Historical Artifacts Be Legally Kept if Found While Detecting?
Found something historical? You can’t legally keep it. Artifact recovery on public lands violates federal and state law, making legal ownership impossible. Even on private property, you’ll need written landowner permission before keeping any discoveries.
