Other organizations at this address

1 other organization in the IRS Business Master File lists the same street address. matched by us

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2025

Mission

We work to integrate the science of natural assets with tools, policies and management decision-making for public benefit.

Activities or mission (Part I)

SIG-NAL is a non-profit organization with a mission to develop and apply the scientific foundation needed to link economic and environmental interests by accounting for the full value of natural assets. (continued at top of next page)

  • The Regional Wildfire Mitigation Program (RWMP) will create a framework to increase wildfire resilience for the wildland urban interface (WUI) communities located in the south coast region of Santa Barbara County, and is funded by the National Wildlife Foundation. The Program will transform the front country into a fire-adapted region with reduced wildfire risk to the communities, the built environment and natural systems, while allowing wildfire to play a regenerative role across the landscape.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

As filed, from the IRS e-Postcard file of 2 November 2026. The IRS publishes only each organization's most recent postcard, so earlier years are not shown. A 990-N carries no financial detail. The postcard also gives the principal officer's address, which is not shown here.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

Taxable family

From Schedule R Parts I, III and IV: entities that legally are the filer, and taxable partnerships, corporations and trusts it is related to. These record ownership and control, not shared board members or money.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.

What this page reflects
