Summary
This spreadsheet establishes the cost-share percentage allocated to each commercial entity occupying HOA-owned wetlands property adjacent to the Prestonfield subdivision. The document was created by Costello — likely Pat Costello, the HOA’s attorney, who was suggested in July 2024 minutes and whose firm handles cost-share billing as of 2025. The methodology is acre-based: a rate of 1.953338% of total shared costs per acre is applied to each occupant’s land area.
The document presents two views: an “Original Parcels” section showing the two basins as single undivided parcels (the historical baseline), and a “Current Parcels” section showing how those same 27.86 total acres are subdivided among six current parcels held by four distinct entities. Both views produce the same 54.42% total, confirming the rate has not changed as parcels were subdivided. The HOA absorbs the remaining 45.58%.

Notable Details
- Kornerstone, LLC appears three times as separate parcels. One is labeled “(Ditch Witch)” — the business name previously referenced in meeting minutes since 2021. The other two lack distinguishing labels; the basis for the three-way split is not documented.
- “McCollister,” named in November 2022 meeting minutes as a paying party, does not appear in this document. Their status is unknown — they may have vacated, sold, or been otherwise removed from the billing list.
- No document date is present on the spreadsheet itself.
