“Director David Hansen is married to sister f Director Ralph Mihan”
“Form 990 and associated schedules are emailed to all board members for a week's review prior to submitting to the IRS”
“Two board members annually monitor two of the easements and provide a written report. An independent contractor has been retained to monitor the new easement which is much larger than the other two. In all cases a baseline report was prepared for comparison purposes. There have so far been no violations of the easements held by Marin Open Space Trust.”
“Directors and officers do not receive any compensation. Marin Open Space Trust does not have any employees.”
“Tax documents are available upon request”
“Marin open space trust has adopted policies including many based on land trust alliance recommendations. Marin open space trust has policies regarding monitoring and inspection, baseline preparation, stewardship records, amendment policy and procedures, enforcement, stewardship funding, and hazardous materials”
“Marin open space trust places no value on conservation easements that it holds as they have no associated value. This is based on the purpose of the easements to preserve and protect the conservation values of the properties as wildlife habitat and open space, and to prevent uses of the properties that would interfere with these conservation values.”
