Coverage & caveats

Folsom, CA has TWO parallel residential impact-fee regimes. (1) CITYWIDE impact fees apply to standard development in the established city (largely north of Highway 50). These are the PRIMARY per-dwelling-unit rows below and are the figures included in the running total. (2) The FOLSOM PLAN AREA (FPA) impact fees are a SEPARATE regime for the large master-planned growth area south of Highway 50 (per FMC Ch. 3.120, Measure W); these are mutually-exclusive with the citywide fees, so all FPA rows are marked excludeFromTotal=true (a builder pays EITHER the citywide set OR the FPA set, never both). A builder in the FPA pays the FPA Specific Plan (FPASP) fee ($16,094/SFR — bundles parks, trails, police, fire, library, municipal/community center, aquatic center) PLUS FPA transportation fees (Hwy 50 Improvements $1,658, Hwy 50 Interchange $3,375, Transit $1,714, plus a Sacramento County Transportation Development Fee), Corporation Yard $1,623, and FPA Solid Waste $611 — plus the same citywide water/sewer connection fees and school fees. All citywide impact-fee amounts are taken from the City of Folsom "Developer Impact Fee Compliance 2024 / AB1600 Development Fees Annual Report for the Fiscal Year ended June 30, 2024" (accepted by Resolution 11311, Dec 10, 2024) — the most recent full schedule available; fees are CPI-indexed annually so current (2026) amounts may be a few percent higher. Representative SFR is per-unit (Folsom's citywide impact fees are flat per dwelling unit, NOT tiered by square footage, so no size-tier selection was needed). Multifamily ("Multi-Family Residential") rows included per unit. SCHOOL FEES (separate district): Folsom lies in Folsom Cordova USD School Facilities Improvement District No. 2 (SFID 2). FCUSD's April 2025 board-approved School Facility Needs Analysis justifies a Level II developer fee of $9.96/sq ft of new residential construction in SFID 2 (Folsom) (Level I statutory residential ~$5.17/sq ft is the fallback; Level III would be $19.92/sq ft). The $9.96/sq ft Level II row is the real builder cost in Folsom and is attributed to the school district. School fee is per-square-foot, so it is NOT additively included in the per-unit total (a ~2,000 sf SFR would owe roughly $19,900 in school fees on top of city fees). WATER/SEWER: Water Capital Improvement (Water Connection Fund 521) SFR = $3,813/unit (FMC 13.24.060). Sewer Capital Improvement SFR = $1,217/unit. A separate, ADDITIVE Water Impact Fund fee = $1,117/SFR (FMC 13.30.030) is also charged. Regional sewer treatment connection (Sacramento Regional County Sanitation District / SacSewer) is a separate additional charge not captured here. CATEGORIES THAT DO NOT EXIST / NOT APPLICABLE as flat residential per-unit fees: Supplemental Park Improvement fee — the schedule explicitly states "This fee is no longer charged." Housing Trust Fund fee — applies to non-residential only ($1.99/gross sq ft office/retail/industrial), NOT residential, so excluded from residential total. Inclusionary Housing in-lieu fee — formula-based (1% of lowest-priced for-sale unit × number of units; 0.5% for custom-lot subdivisions), no fixed per-unit dollar amount. Tree Planting & Replacement — $250.00 per inch mitigation in-lieu, only if protected trees are removed (conditional, not a standard per-unit fee). California does not permit a municipal "school impact fee"; school facilities fees are levied by the school district (captured above). Mello-Roos/CFD special taxes are out of scope per instructions (FPA includes substantial CFDs). VERIFY: confirmed 30 of 30 rows; dropped 0. Every amount and sourceQuote was independently re-fetched and matched against its cited source. The primary AB1600 FY2023-24 report PDF (sourceIndex 0) was re-downloaded and all 23 city/FPA fee-schedule amounts were located verbatim via pdftotext -layout: Transportation SFR $9,266 / MF $6,486; City-Wide Park SFR $7,984 / MF $5,303; General Park Equipment SFR $106; Police SFR $681 / MF $773; Fire SFR $1,232 / MF $1,191; General Capital SFR $1,811 / MF $1,811; Drainage SFR $1,176; Humbug-Willow Creek SFR $313; Light Rail SFR $821; Sewer Capital SFR $1,217 / MF $952; Water Impact SFR $1,117; Solid Waste SFR $411; FPA Hwy 50 Improvements $1,658; FPA Hwy 50 Interchange $3,375; FPA Transit $1,714; FPA Corporation Yard $1,623; FPA Specific Plan $16,094; FPA Solid Waste $611. The Water Capital Improvement SFR figure was OCR-mangled in text extraction, so it was confirmed by rendering physical PDF page 42 to an image: Water Connection Fund 521, Single Family Residential Per Unit = $3,813 (with commercial 3/4" meter = $3,803, confirming structure), MF = $2,478. The Inclusionary Housing formula and Tree Planting $250/inch quotes were located verbatim; Supplemental Park's "This fee is no longer charged" and Housing Trust Fund's non-residential $1.99/gross sq ft were also confirmed (correctly excluded). The FCUSD 2025 SFNA (sourceIndex 2) was re-downloaded and confirms verbatim: "$9.96 per square foot of new residential construction in the SFID 2" (SFID 2 = City of Folsom, area south of Highway 50), Level III SFID 2 = $19.92/sq ft, Level II board-approved April 18, 2024. FMC Ch. 3.120 (sourceIndex 1) is live (HTTP 200) and confirms FPA Highway 50, Transit, Corporation Yard, and Specific Plan impact fees under section 3.120.040. Resolution 11524 (sourceIndex 3) and the FCUSD webpage (sourceIndex 4) are both live. excludeFromTotal corrections: NONE — all flags verified correct. The 13 citywide SFR rows (incl. additive water/sewer connection fees) sum to $29,948, which is sane and free of double-counting; each of the 7 multifamily variants, the per-sq-ft school fee, the formula-based inclusionary fee, the conditional tree-mitigation fee, and all 6 FPA rows are correctly excluded from the total to avoid mixing unit bases or double-counting the mutually-exclusive FPA regime.

Primary total reflects the CITYWIDE residential impact-fee regime per dwelling unit (SFR). FPA-area fees, alternate land uses, the per-sq-ft school fee, and conditional/non-residential fees are marked excludeFromTotal to avoid double-counting or mixing unit bases. All figures verbatim from the cited FY2023-24 AB1600 report (CPI-indexed annually). The Water Capital (connection) SFR amount was OCR-mangled in text extraction and was independently confirmed against a rendered image of source page 42 ($3,813). Citywide SFR sum = $29,948.
