Governance Explanations

Form 990, Part VI, Section B, Line 11B

San Bruno Mountain Watch hires an independent tax professional to prepare Form 990 in collaboration with the organization's executive director and treasurer, who review the contents of the return. The final version the tax return is provided to each member of the organization's governing body for review. The executive director and treasurer then authorize the return. It is e-filed with the Internal Revenue Service.

Form 990, Part VI, Section B, Line 12C

The Organization's Conflict of Interest Policy provides that directors, officers and key employees review all potential conflicts of interest, beginning at the annual board retreat at the start of the fiscal year. At this time, directors, officers and key employees must submit a written questionnaire to disclose potential conflicts and affiliations. Throughout the year, they must notify the organization if they become aware of any errors or material changes in the information provided in the questionnaire. This process helps the organization identify and resolve potential conflicts and monitor compliance with the Conflicts of Interest Policy.

Form 990, Part VI, Section B, Line 15A

Members of the organization's board of directors review the compensation of the executive director on an annual basis. Compensation data is gathered from the tax return filings of comparable organizations in the surrounding geographic area. The organization's finance committee proposes the appropriate compensation for the executive director as part of the annual budget planning process. The board of directors reviews the recommendation and meets to determine and approve the compensation and the annual budget.

Form 990, Part VI, Section B, Line 15B

Members of the organization's board of directors and the executive director review the compensation of other key employees annually. Compensation data is gathered from comparable organizations in the surrounding geographic area by reviewing materials such as job postings. The organization's finance committee proposes the appropriate compensation for other key employees as part of the annual budget planning process. The board of directors reviews this recommendation and meets to determine and approve the compensation and the annual budget.

Form 990, Part VI, Section C, Line 19

The organization's governing documents, conflict of interest policy and financial statements are maintained at the organization's office in Brisbane, California and stored electronically. They are made available by request to the public. Tax returns are posted on the organization's website at www.mountainwatch.org/financials and available from independent websites such as the electronic files maintained by the California Attorney General's Registry of Charitable Trusts.

IRS990/Desc0Mission Blue Nursery Program San Bruno Mountain Watch operates the Mission Blue Nursery to grow the native flora of San Bruno Mountain. In 2024, San Bruno Mountain Watch continued hosting programs at the nursery for the public to participate in plant propagation and maintenance activities. Nursery volunteers contributed 989 hours of service at the nursery during this year.Volunteers also assisted with seed collection efforts on San Bruno Mountain. The nursery grew native plants for various restoration projects on San Bruno Mountain and propagated rare and endangered plants for plant conservation and seed amplification projects. Native plants were also provided to other urban greening projects throughout the San Francisco Peninsula. The nursery hosted three public plant sales offered plants through individual plant pick-up appointments, and donated plants to community garden partners who are beneficiaries of the Environmental Justice Fund at Mission Blue Nursery. The nursery also hosted artistic community events such as a native plant wreath making workshop, a container plant arrangement workshop, and botanical illustration activities.

IRS990/ProgSrvcAccomActy2Grp/Desc0Ecological Restoration Program San Bruno Mountain Watch leads ecological restoration efforts with community volunteers, students, corporate groups, park agencies, and local cities. Volunteers contributed 1,262 hours to community-based ecological restoration efforts in 2024. San Bruno Mountain Watch continued grassland restoration efforts as part of the San Bruno Mountain Habitat Conservation Plan, planting native host and nectar plants to improve habitat for the mountain's endangered Mission Blue and Callippe Silverspot butterflies.The group also carried out rare plant conservation and revegetation efforts for the endangered San Bruno Mountain manzanita and seed amplification of the San Francisco campion. Invasive plant removal efforts continued in areas like the San Bruno Mountain Dunes, the Northeast Ridge, Buckeye and Owl Canyons, and the southern slopes of the mountain. The San Bruno Mountain Botanical Garden continued to expand with the planting of new sections and the addition of botanical signage. San Bruno Mountain Watch also continued restoration efforts within salt marsh and transitional habitats at the shoreline of Colma Creek. The creek begins on San Bruno Mountain and drains into San Francisco Bay. Additionally, the organization began planting at the headwaters of Colma Creek on the mountain and continued planting and maintaining the San Bruno Mountain Test Plot, an experiment that explores the ability of native plants to grow in the understory of historic stands of introduced non-native eucalyptus trees on the mountain.

IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt0San Bruno Mountain Watch hires an independent tax professional to prepare Form 990 in collaboration with the organization's executive director and treasurer, who review the contents of the return. The final version the tax return is provided to each member of the organization's governing body for review. The executive director and treasurer then authorize the return. It is e-filed with the Internal Revenue Service.
IRS990ScheduleO/SupplementalInformationDetail/ExplanationTxt1The Organization's Conflict of Interest Policy provides that directors, officers and key employees review all potential conflicts of interest, beginning at the annual board retreat at the start of the fiscal year. At this time, directors, officers and key employees must submit a written questionnaire to disclose potential conflicts and affiliations. Throughout the year, they must notify the organization if they become aware of any errors or material changes in the information provided in the questionnaire. This process helps the organization identify and resolve potential conflicts and monitor compliance with the Conflicts of Interest Policy.
