“David Kent: YesExplanation: Yes, a farming business owned by my two daughters leases 10 acres of vineyards from Mark & Maria Triska.Mark Triska: YesExplanation: I have a business relationship with David Kent as I am his winegrape grower for Darcie Kent Vineyards.”
“Tvc has a board of directors. Five of the directors are appointed by five organizations: city of livermore, city of pleasanton, county of alameda, livermore valley winegrowers association and friends of open space and vineyards. The other seven director seats are considered "at largex and are voted upon by the current board. There are no other members - all donors and advisory council are considered "friends" of tvc. All are considered volunteers.”
“Committees are not authorized to make decisions for tvc, they investigate and prepare proposals to the board of directors who make the decisions. The committees can make recommendations however the board can choose to modify and/or reject recommendations by the committees.”
“Form 990 was prepared by the accountants and sent to the officers for review and approval before filing. The form 990 will be available to any board member who requests a copy of the document.”
“Annually, each director is requested to review, update, and sign the conflict of interest form from the previous year. Additionally, at the beginning of each board of director and committee meetings everyone is asked to identify if there are any possibilities of a conflict of interest. Anyone identifying themselves with a conflict of interest is documented in the minutes. The individuals who have a conflict of interest for a specific item has/will recuse themselves from the room during the discussion and decision votes (this is all documented in the minutes).”
“Review of agreed expectations for the year, personnel committee sends out review forms to each director, plus the executive director conducts a self evaluation. Additionally, pay is compared to the annual nonprofit compensation associates annual survey for "fair pay for northern california nonprofits".”
“For other employees reviews are completed by the executive director. Expectations versus accomplishments and "fair pay for northern california nonprofits" annual survey is used.”
“Tvc prepares an annual report each year. A financial statement, annual report and form 990 is posted for public viewing on the tvc website, guidestar and charity navigator. Monthly financial reports are distributed to the board of director's via email. Additionally, the reports are available for review upon request.”
“Other program services 4: other program servicessupporting a vibrant wine country in 2021, tvc commissioned a study from the uc agricultural issues center on grape growing and winemaking in the livermore valley from professors, james t. Lapsley, phd. And daniel a. Sumner, phd., from uc davis. The purpose of the study is to identify measurable and achievable goals for leaders and growers to ensure the future of the livermore wine region. The region has the right combination of soil, climate, water and expertise to grow world class wine grapes with almost 7,000 prime farmland acres. Yet, half of all livermore vineyards are under ten acres in size and 80 percent are 20 acres or smaller. In order for livermore valley to be regarded as a premiere wine growing region, the region will need to achieve a critical mass of 5,000 vineyard acres, a key goal of the south livermore valley area plan. To further invest in the region, tvc is supporting the mt. Diablo highlands wine quality alliance (wqa), changing the american viticulture area (ava), and extending sewer beyond the existing urban growth boundary. The wqa is dedicated to improving the quality of wines and fruit from the livermore appellations. In 2021, the wqa began working with a winemaking consultant to provide education, expert consultation and technical analysis to increase the recognition and reputation of livermore valley wine. Another way tvc wants to invest in the livermore wine country is by providing sewer service to current and future wineries in the livermore winegrowing region. This way, wineries can expand sustainably. In 2021, tvc petitioned the livermore city council to place an initiative on the november 2022 ballot to extend sewer services to rural alameda county.”
“Tri-valley conservancy is certified by the land trust alliance and abides by the policies and procedures related to monitoring, inspection and enforcements of the conservation easment. The organization maintains an endowment account is to ensure property stewardship of tvc's easements and property interests by funding its legal, operating and monitoring activities in perpetuity.”
“Through its years of operation, tvc has acquired sixty-six deeds of perpetual agricultural or open space easements totaling 5,111 acres. These easements have no financial value since the development rights associated with the properties have been permanently "extinguished". Therefore, the easements are valued nominally at $1 each, for a total of $66 in these financial statements.certain residential developments within the boundary of the plan area are required to pay tvc mitigation fees at the time individual building permits are pulled (ruby hill development in pleasanton, ca) or in other cases at the time of final map approval. Such fees have been collected by the city of pleasanton, and tvc anticipates revenues from the remaining four plus residential lots still available in the ruby hill development. All monies received from ruby hill are restricted for use within the south livermore valley area plan (slvap). Tvc uses the developer mitigation fees it receives from ruby hill to purchase conservation easements, to steward the portfolio of easements under its care and to cover its general and administrative operations. Tvc accepts and holds conservation easements committing to annual stewardship in perpetuity, to enforce their terms and to building positive landowner and community relationships to support its conservation programs and enforcement actions. For every easement, tvc has a baseline documentation report prepared prior to closing and signed by the landowner at closing. The report documents the improvement conservation values protected by the easement and the relevant conditions of the property as necessary to monitor and enforce the easement(s). The easement properties are monitored regularly, at least annually, and documentation is kept of each monitoring activity. Tvc maintains regular contact with owners of easement properties. Changes in land ownership are tracked. Tvc strives to promptly build a positive working relationship with new owners of easement properties and informs them about the easement's existence and restrictions, and tvc's stewardship policies and procedures. Part of the stewardship effort requires tvc to take necessary and consistent steps to see that violations are resolved utilizing legal resources for enforcement and defense when necessary.”
“The primary purpose of the endowment account is to ensure property stewardship oftvc's easements and property interests by funding its legal, operating and monitoring activities in perpetuity.”
