Summary
The HOA owns 27.86 acres of wetlands property on which certain commercial entities operate. Those entities are billed annually for a proportionate share of the HOA’s maintenance costs for that property. The apportionment is acre-based: each party pays 1.953338% of total shared costs per acre they occupy. Collectively, the commercial parties cover 54.42% of total costs; the HOA absorbs the remaining 45.58%. As of July 2025, the HOA attorney manages billing and collection.
Legal Origin
The cost-share obligation traces to the Non-Exclusive Permanent Easement Agreement recorded October 11, 2002 (DuPage County Document No. R2002-268796). Original parties:
- Grantor: Prestonfield, LLC. (nominee of Concord Homes, Inc.) — the residential developer
- Grantee: Suburban Bank Trust No. 73-3244 (nominee of P.K.I., LLC.) — the original commercial party
Paragraph 13 of that agreement explicitly mandated CEMCON, Ltd. to perform the cost allocation calculations based on proportionate runoff from each tributary property. This gave CEMCON’s engagement a contractual basis predating the HOA itself.
The original parcels subject to the easement were subsequently subdivided under the Plat of Subdivision for Prestonfield Unit 4 (recorded October 18, 2004, Document No. 2004-267393):
| Original Exhibit | Became |
|---|---|
| Exhibit A (Grantor) — 14.19 acres to N. SWMF; 13.67 acres to S. SWMF | Lot 219 → Crossings of DuPage Unit 1 → Crossings of DuPage Unit 2 |
| Exhibit B (Grantor) — Northerly SWMF | Lot 218 (northerly stormwater management facility) |
| Parcel D | Right-of-way for Shingle Oak Drive |
| Exhibit E (Grantee) — Southerly SWMF | Lot 220 (southerly stormwater management facility; the Kornerstone/Ditch Witch parcel) |

Calculation Methodology
Cost shares are calculated based on acreage at a rate of 1.953338% per acre, derived from the original parcel structure:
| Original Area | Acres | Cost Share % |
|---|---|---|
| Area 1 – North Basin | 14.19 | 26.44% |
| Area 2 – South Basin | 13.67 | 27.98% |
| Total | 27.86 | 54.42% |

| West Chicago Fire Dist | 2.50 | 4.883% |
| Atlantic Drive Condos | 2.50 | 4.883% |

| Kornerstone, LLC | 2.46 | 4.805% |

What Is Billed
Costs are organized by basin and include:
- Natural area management and burns — Hey & Associates (both basins)
- Landscaping — Fisher Burton (South Basin)
- Utilities — ComEd electric (North Basin pond; disconnected 2025)
- Pond aerator service — SOLitude Lake Management (formerly Rollins Aquatic Solutions; North Basin; confirmed through 2021; $80 in 2021)
- Burn treatments (added to 2026 budget for both basins)
- Attorney fees for preparing and collecting cost share (added going forward as of July 2025)
Pre-2022 Calculation Methodology
Through at least 2021, cost shares were calculated using a three-section formula with within-group percentages rather than the current acreage-based approach. The April 2022 packet contains a detailed calculation email from Courtney Puzon (API) showing the 2021 methodology:
Within-group percentages (2021): McCollister 45.38% / Ditch Witch 43.43% / Condos 11.19% (West Chicago Fire District not yet included)
Section 1 — Hey & Associates: Total Hey cost × 0.666 (two of three basins) × 0.27 = commercial share, split by within-group percentages.
Section 2 — ComEd + Rollins Aquatics: (ComEd + Rollins total) × 0.27 = commercial share, split by within-group percentages.
Section 3 — Fisher Burton: Fisher total × 0.5385 (proportion of mowing in wetland buffer areas: 5.74 of 10.66 total mowed acres, per GIS analysis) × 0.27 = commercial share, split by within-group percentages.
The 0.27 multiplier and within-group percentages differ from the current formula (1.953338%/acre of the 27.86-acre total). The transition to the current acreage-based formula is not documented in any ingested source. Source: board-packet-2022-04-14

| 2022-07-21 | Hey 2021 billing discrepancy resolved. The $10,200 Hey paid in fiscal 2021 (vs. $8,500 contracted) is explained: a $2,450 invoice dated 2/17/2021 was for 2020 work — mailed to PSI (prior manager) and never processed; API paid it upon receipt. True 2021 billing = $7,750 (in-year) + $750 fall clean (paid 1/13/2022) = $8,500 per contract. The $2,450 overage was a timing artifact, not an over-budget expense.

Open Questions
- McColister (also spelled “McCollister” in later minutes) — a “Shared Maintenance” charge of $225.00 appears in the April 2020 AR Aging (Over 90 bucket), predating the Board’s formal April 2021 billing. McColister was then billed $5,158.42 in April 2021 as the largest cost-share party, and named as paying in November 2022 minutes, but is absent from the current cost-share spreadsheet (cost-sharing-percentages). Given the amount billed in 2021, McColister likely held a large parcel — possibly what is now WPT Shingle Oak Drive LP (22.815%, the largest current party). Parcel may have been sold or transferred. The origin of the pre-2021 $225.00 charge and the full billing history prior to April 2021 have not been explained in any ingested source.
- Kornerstone, LLC three-parcel split — Kornerstone holds three separate parcels (one labeled “Ditch Witch,” two unlabeled). The basis for this subdivision is not documented. Note: the Ditch Witch parcel is identified as Outlot 220 in PSI records; confirmed as the southerly SWMF location (Lot 220 in Prestonfield Unit 4) by the February 2020 CEMCON proposal parcel genealogy. Source: cemcon-proposal-2020-02-21
- Ditch Witch / Kornerstone payment dispute — legal action was authorized in July 2021. Whether fully resolved is unknown.
- Fire station retroactive billing — the fire station was confirmed on HOA property and added to billing in 2025. Whether prior years are owed retroactively is unknown.
- McCollister 2021 charge not applied — the May 2023 board packet reveals the 2021 cost share of $2,253.42 was never posted to McCollister’s account (API error). The April 2022 board packet noted a $2,253.42 “prepaid credit” in McCollister’s AR, which may reflect a different payment. Whether the 2021 amount was ultimately billed and collected is not confirmed in any subsequent ingested source.
