Coverage & caveats

All city impact/connection fees are from the American Fork City ADOPTED Fee Schedule, Effective July 1, 2025 (adopted June 10, 2025) — the current official master fee schedule (high confidence, exact quotes). American Fork levies city impact fees for: Culinary Water (by meter size), Fire, Parks & Recreation, Police, Pressurized Irrigation (per irrigated sq ft), Sanitary Sewer (city collection, by meter size), Storm Drain (per gross sq ft), and Roads (with separate non-TOD and TOD rate sets). Separate, ADDITIVE city "Utility Hook Up Fees" exist for Water connection, Sewer connection, and Pressurized Irrigation connection (these are tap/connection fees charged on top of the impact fees). PRIMARY ROWS: For single_family_detached I used the per-unit categories plus the 3/4" meter water impact fee, the 3/4" meter sanitary sewer impact fee, and the non-TOD road impact fee. All larger meter sizes, all TOD road variants, and all multifamily variants are marked excludeFromTotal=true (they are mutually-exclusive alternatives or a different land use). Storm Drain ($0.1536/gross sq ft) and Pressurized Irrigation ($0.42/irrigated sq ft) impact fees are charged per square foot, not per dwelling unit, so they are included with their published per-sqft basis and marked excludeFromTotal=true (cannot be expressed as a fixed per-DU amount without assuming lot/irrigated area). SEPARATE DISTRICT (must be paid by an AF residential builder): Sanitary sewer TREATMENT impact fees are levied by Timpanogos Special Service District (TSSD), not the city. Per the American Fork Building Department, effective January 1, 2026 the TSSD impact fee is $5,793.00 per ERU (decreased from $5,931.00); all permits issued after Dec 31, 2025 are charged $5,793.00. This is collected on the city building permit but paid to TSSD; the city also adds a $15.00 TSSD Sewer Impact Processing Fee. The TSSD Dec-2025 Impact Fee Analysis (Zions Public Finance) shows a MAXIMUM allowable 2026 fee of $7,023.05/ERU, but TSSD ADOPTED the lower $5,793.00, which is what builders actually pay. NOTE: the city's own "Sanitary Sewer Impact Fee" (e.g., $840.08 for 3/4" meter) is the city COLLECTION-system impact fee and is separate from and additive to the TSSD treatment impact fee. WHAT DOES NOT EXIST HERE: NO school impact fee — Utah law (Utah Impact Fees Act, UCA 11-36a) does not authorize school impact fees, and Alpine School District does not charge one. NO general/capital, library, open space, affordable housing, or stand-alone "drainage" impact fee beyond the Storm Drain impact fee listed. NO separate transportation/highway-district fee (roads handled by the city Roads Impact Fee). CAVEATS: The underlying impact fee facility plans/analyses on the city's Impact Fees page are dated 2017, but the DOLLAR AMOUNTS reported here are the currently adopted FY2025-26 figures from the master fee schedule (current). Pressurized irrigation is a service some lots use in lieu of culinary water for outdoor watering; both its impact fee ($0.42/irrigated sq ft) and its connection fee ($475 for 3/4") apply where PI service is provided. VERIFY: confirmed 23 of 23 rows; dropped 0. Independently re-read the full FY2025-26 Adopted Fee Schedule (sourceIndex 0) via reader proxy — every city impact-fee and hook-up-fee amount matches verbatim: Culinary Water 3/4"=$2,502.45, 1"=$4,179.09, 2"=$13,338.06 (fee schedule line ~285-288); Fire SFR=$429.30, MFR=$392.08 (line ~294-295); Parks SFR=$3,855.99, MFR=$3,064.51 (line ~299-300); Police SFR=$326.45, MFR=$216.55 (line ~302-303); Sanitary Sewer (collection) 3/4"=$840.08, 1"=$1,402.93 (line ~310-311); Roads SFR non-TOD=$3,548.30, SFR TOD=$3,016.05, MFR non-TOD=$2,003.07, MFR TOD=$1,702.61 (line ~326-329); Storm Drain=$0.1536/gross sq ft (line ~319); Pressurized Irrigation impact=$0.42/irrigated sq ft (line ~306); Water hook-up 0.750"=$475.00 (line ~350); Sewer hook-up=$235.00 (line ~357); PI hook-up 0.750"=$475.00 (line ~359); TSSD Sewer Impact Processing Fee=$15.00 (line ~323). TSSD treatment fee $5,793.00/ERU confirmed verbatim via search-engine snippet of the city Building Department page (host unreachable for direct fetch); TSSD max-allowable $7,023.05/ERU independently confirmed in the TSSD IFA PDF (sourceIndex 3). excludeFromTotal corrections: none — all flags already correct (larger meters, TOD variants, all multifamily rows, per-sqft Storm Drain and PI impact fees, and the PI connection fee are properly excluded; the 6 primary SFD per-unit rows plus Water $475 and Sewer $235 hook-ups are kept and do not double-count). Representative SFD fixed per-unit city total = $2,502.45 + $429.30 + $3,855.99 + $326.45 + $840.08 + $3,548.30 + $475.00 + $235.00 = $12,212.57 (sane); plus separate-district TSSD $5,793.00 + $15.00 processing = $18,020.57 all-in, before the per-sqft Storm Drain/PI impact fees and optional PI connection. CONFIDENCE DOWNGRADE: the TSSD treatment-fee row (sourceIndex 2) lowered from high to medium because it was confirmable only via a verbatim search-engine snippet (the city Building Department host timed out on direct fetch), though the snippet matched exactly and the TSSD PDF corroborates the ceiling.

Representative single_family_detached per-dwelling-unit city impact fees (additive): Culinary Water (3/4" meter) $2,502.45 + Fire $429.30 + Parks & Rec $3,855.99 + Police $326.45 + Sanitary Sewer city collection (3/4" meter) $840.08 + Roads non-TOD $3,548.30 = approx $11,502.57 in fixed per-unit city impact fees. Add additive connection/hook-up fees: Water $475.00 + Sewer $235.00 = $710.00 (Pressurized Irrigation connection $475.00 applies only on PI lots). Add separate-district TSSD sewer treatment impact fee $5,793.00/ERU (+ $15.00 city processing). Storm Drain ($0.1536/gross sq ft) and Pressurized Irrigation ($0.42/irrigated sq ft) impact fees are additional but vary by lot/area. Multifamily per-unit equivalents and larger-meter / TOD variants are included as excludeFromTotal rows. VERIFIED 2026-06-17: all amounts re-confirmed verbatim against the FY2025-26 Adopted Fee Schedule; TSSD treatment fee confirmed via Building Department snippet (medium confidence).
