Coverage & caveats

SOURCE: Town of Windsor (CO) adopted master Fee Schedule, Exhibit A, "Updated: 02.01.2026" — the current authoritative 10-page document (windsorgov.com/513/Fee-Schedule). All reported amounts are quoted verbatim from this schedule; high confidence. IMPORTANT JURISDICTION DISAMBIGUATION: Generic web searches repeatedly surfaced data for WINDSOR, CALIFORNIA (townofwindsor.ca.gov — e.g., a "$13,363 traffic impact fee" and "$9,480 park" fee). Those are a DIFFERENT town and were discarded. Only windsorgov.com (Windsor, Weld County, Colorado) figures are reported here. WHAT EXISTS (residential, per the Windsor CO Fee Schedule): 1) ROAD IMPACT FEE (transportation) — WMC Ch.17 Art.XV (Res 2024-35), fees effective June 1, 2023, reproduced in the current Feb 1, 2026 schedule (page 9): SFD $8,245/dwelling, Multi-Family $5,345/dwelling, Mobile Home Park $3,561/site. (Commercial/office/industrial road impact fees also exist per 1,000 sq ft, not reported — focus is residential.) 2) PARK AND TRAIL DEVELOPMENT FEE (parks) — WMC §15-15-50 (Ord 2018-1563): $8,650, required at final plat approval, paid with building permits (page 7). Annually escalated by a Construction Cost Index ("CCI for 2024 rate was 3%"). 3) SEWER PLANT INVESTMENT FEE (sewer connection / capacity, CO "tap"/PIF) — WMC §13-1-10 (Res 2024-77), page 4: 3/4" meter $7,454, scaling up by meter size. 4) WATER PLANT INVESTMENT FEE (water connection / capacity / PIF) — WMC §13-2-70, page 5: 3/4" meter $8,708, scaling up by meter size. SEPARATELY, RAW WATER FEES ("Consult Engineering Department — varies by subdivision") apply on top of the water PIF; a water-dedication/cash-in-lieu requirement that cannot be reduced to a flat per-unit number and is NOT a fee row (could add materially to all-in cost). 5) STORM DRAINAGE "NEW GROWTH BASIN IMPACT FEE" (drainage) — WMC §13-3-60 (Ord 2025-1735), page 6: collected when >350 sq ft of new impervious surface is built. FORMULA-BASED: Fee = (Impervious Rate Factor) × ($0.304803/sq ft) × (net lot area). Medium-density SF Impervious Rate Factor = 0.40. Lot-area dependent, so no fixed per-dwelling-unit row reported. REPRESENTATIVE ALL-IN (SFD, 3/4" meter, excluding lot-dependent drainage and subdivision-dependent raw-water): Road $8,245 + Park/Trail $8,650 + Sewer PIF $7,454 + Water PIF $8,708 = $33,057 fixed per-unit/per-3/4"-meter fees, PLUS storm-drainage basin impact fee (lot-area dependent) PLUS raw water fee (subdivision dependent). NORMALIZATION: Sewer and Water PIFs are priced by meter size; the standard residential 3/4" meter is the primary row for each, with the 1", 1.5", and 2" variants marked excludeFromTotal=true as mutually-exclusive meter-size variants. Multi-family and mobile-home Road Impact Fee rows are separate land uses (not excluded). No home-square-footage tiering exists (Road and Park fees flat per dwelling). WHAT DOES NOT EXIST HERE (omitted): NO standalone school IMPACT fee — Windsor uses SCHOOL SITE LAND DEDICATION (WMC Ch.17 Art.XIV, page 7) priced per acre by district (RE-4 $156,000/acre Ord 2019-1587; Poudre R-1 $95,000/acre; Thompson R2-J $106,325/acre), a per-acre land-dedication/fee-in-lieu obligation at plat stage, NOT a flat per-dwelling impact fee. NO separate police, fire, library, open-space, general/municipal-facilities, affordable-housing, or general "mitigation" impact fee published. Page-8 "¾" Meter $70 / Transponder $328 / Yoke $150" are equipment/meter-purchase costs, not impact/capacity fees. Building permit fees are SAFEbuilt + 25% Town admin + 3.65% use tax (valuation-based), not flat impact fees. DATA CAVEATS: (a) Water PIF source line shows "Res 2027-76," an evident typo in a Feb-2026 document; the AMOUNT ($8,708) is taken as printed and confirmed. (b) Source-2 (June 2023 Road Impact Fee notice, Ord 2023-1675) lists SUPERSEDED prior-cycle figures (SFD $6,715 / MF $4,353 / MHP $2,900); the current adopted figures are those on the Feb 2026 master schedule (Res 2024-35: SFD $8,245 / MF $5,345 / MHP $3,561), which govern — sourceIndex for all road rows is the master schedule (0). (c) Sewer 3" row carries a different ratio (13.86) but the same printed amount ($45,854) as the 2" row — apparent table error in source; 3" not reported. (d) Population: source now reflects a 2026 estimate of 46,001 and a 2020 Census of 33,231 (researcher cited 43,371 as a July-2025 estimate and 33,241 for 2020 Census); population is an estimate, not a fee, and does not affect fee verification — researcher's 43,371 retained as the July-2025 figure. VERIFY: confirmed 12 of 12 rows (all amounts and sourceQuotes confirmed verbatim against the authoritative master Fee Schedule pages 4, 5, 7, and 9); dropped 0; excludeFromTotal corrections: none (all 6 larger-meter sewer/water variants correctly flagged excludeFromTotal=true; the four primary rows — Road SFD, Park/Trail, Sewer 3/4", Water 3/4" — and the two separate-land-use Road rows MF and Mobile Home Park correctly NOT excluded). Representative SFD per-unit total ($33,057) confirmed sane and not double-counting. Source-2 road notice found to be SUPERSEDED (older numbers) but does not affect any reported row since road rows cite sourceIndex 0; flagged in caveats.

All figures verified verbatim from the Town of Windsor, CO master Fee Schedule (Exhibit A, updated 02.01.2026), pages 4-9. Residential one-time development fees a builder pays: Road Impact Fee (SFD $8,245 / MF $5,345 per dwelling, page 9), Park & Trail Development Fee ($8,650 per dwelling, CCI-escalated annually, page 7), Sewer Plant Investment Fee ($7,454 at standard 3/4" meter, page 4), and Water Plant Investment Fee ($8,708 at standard 3/4" meter, page 5). PIFs scale up with meter size (larger-meter rows included as excluded variants). Two additional growth charges cannot be reduced to a flat per-unit number and are documented in coverageNotes rather than as fee rows: the formula-based Storm Drainage New Growth Basin Impact Fee (depends on lot impervious area, page 6) and the subdivision-specific Raw Water Fee (water dedication, page 5). School obligations are handled via per-acre school-site land dedication (RE-4 $156,000/acre, page 7), not a flat per-unit impact fee. No separate police, fire, library, open-space, general-facilities, or affordable-housing impact fees exist in Windsor CO. The June 2023 road-fee notice (sourceIndex 1) contains superseded prior-cycle road numbers and is retained only for provenance; current numbers come from the master schedule.
