About
About this site
spawnusa.org is an independently operated reference on rain gardens, stormwater runoff, and coastal California salmon habitat.
What it is
A privately run publication. It produces guides, calculators, and reference material on parcel-scale stormwater management and the creek habitat that stormwater affects. It is a commercial website and may earn revenue from advertising, affiliate links, or referrals to contractors. Where that is the case it is disclosed on the page.
What it is not
It is not a nonprofit, does not solicit or accept donations, does not run volunteer events, and does not represent any organization.
Non-affiliation. This domain was previously used by the Salmon Protection and Watershed Network. That organization is now part of the Turtle Island Restoration Network and has no connection to this site. Nothing here should be read as coming from, endorsed by, or associated with either organization. For their current work, go to their own website directly.
Corrections
Technical guidance here is general reference material, not engineering advice. Verify sizing against your local stormwater code before building. Corrections are welcome through the contact page.
