Raging River Quarry Update - Action Requested

Positive News! The Time to Act is Now!

Your voice has made a difference. The purchase of the Raging River Quarry property, with a focus on the southern proposed quarry expansion portion, has moved into active negotiation. Now is a critical time to thank our county officials for support of this purchase of the expansion parcel and ask for the purchase of the ENTIRE property which includes the active mining operation. (if you need more info on the breakdown of the separate properties, etc, please see below.)

What you can do:
If you would like to turn this property into public land, now is the time to let our King County officials know your opinion!

Please send your comments to the following people:

The following talking points are important (it is most effective if you use these points as guidelines, crafting a letter in your own words, and adding your own concerns):

  • At the 2017 Fall City Town Hall Meeting, the County announced that the Raging River Quarry was a priority acquisition. We encourage the County to now finalize this purchase.
  • Thank you for your support of the purchase of the quarry; it’s important that the purchase includes all of the quarry-owned parcels
  • Since the quarry restarted their operations, there has been a noticeable decrease in birds, animals and fish in the surrounding areas
  • There are concerns over the levels of unhealthy dust in the area when blasting, rock crushing and other quarry operations occur
  • The local area has grown considerably since quarry last operated in the 1980s, the quarry is no longer compatible with the residential neighborhood

Thank you very much for your continued support!

More info regarding the properties:
The ‘quarry’ is made up of several parcels. The 26 acre portion that is the proposed quarry expansion has not been developed and is pristine. The active quarry is made up of 25 acres and is operating under a permit issued in the 1980’s with an additional 5 acres reserved for retention ponds. The application for quarry expansion is currently still open.

Thank you!
