Every gift makes a difference!

We believe that the health of our waterways is deeply connected to the health, safety, and economic vitality of our communities.


We invite you to support Coastkeeper as a member, major donor, or partner, and be part of the work that keeps our beaches, harbors, rivers, and streams clean. Every dollar helps.

For a limited time, for every donation of $50 or more, you will receive Coastkeeper's high-quality magazine that you will want to keep and a Coastkeeper decal. This timeless and tangible copy is all about Orange County and a great way to learn about clean water projects and opportunities in your neighborhood.

You can give with confidence knowing that 88 cents of every dollar is spent directly on our high-impact, cost-effective environmental programs.

Gifts made through this appeal represent a gift to Coastkeeper’s entire mission and are tax deductible to the extent allowable by law. Orange County Coastkeeper is a 501(c)(3) nonprofit corporation. Our federal tax ID is 33-0847892.
