Additional Explanations

Form 990, Part IX, Line 11G

“3093 for monitoring of three conservation easements 15180 to Miller Pacific for geotechnical property survey 4000 to EBA Engineering for environmental site assessment 28000 to Conservation Land Group for brokerage services for open space purchase”

Form 990, Part IX, Line 24E

“There are two expenses for this line. The first is 1,360,194 toward purchase of three open space properties. There was also a 50,000 expense which was reimbursement to a donor who had accidentally given a donation twice”

Form 990, Part XI, Line 9

“2023 revenue included non cash donations which do not show up in the bank statements, in addition to rounding errors”

Financial Statement Notes

Schedule D, Part II, Line 5

“Schedule D. Part XIII. Marin Open Space Trust has policies regarding easement monitoring based on Land Trust Alliance recommendations. Policies regard monitoring and inspection, baseline preparation, maintaining stewardship records, amendments and procedures to amend, enforcement, stewardship funding, and hazardous materials.”

Schedule D, Part II, Line 9

“Schedule D Part II Line 9. Marin Open Space Trust contracts with a vendor who monitors easements annually or semi annually and invoices for hours spent in the field and writing reports. A director sometimes accompanies the biologist who does the monitoring. The invoices are listed along with all other invoices and are considered program expenses, paid from operating accounts. One easement was purchased with funding from the State of California, and separate accounting for this easement is a requirement of the grant that funded the purchase. Marin Open Space Trust places no value on these easements s=as they have no associated monetary value. This is based on the purpose of the easements to preserve and protect conservation values of the properties as wildlife habitat and open space”
