Drip edge
Required — Not separately amended by the Town of Basalt. Municipal Code § 18-22's IRC amendment list is a single continuously-numbered sequence, items (1) through at least (24), running from R101.1 through E3401.1 (Electrical); it jumps directly from item (13) (Section R506.2.3, concrete floor vapor retarder) to item (14) (Section R1001.1, masonry fireplaces), with nothing addressing Chapters 7-9 (walls, roof-ceiling construction, roof assemblies) in between -- confirming R905, R907, and R908, including R905.2.8.5, are untouched. § 18-22 states adoption of the IRC "is subject to the following deletions, amendments, additions, and modifications," so the base 2021 IRC drip-edge requirement stands as adopted code where not listed. About drip edge
Ice & water shield
Required — Basalt's amended Table R301.2(1) (Municipal Code § 18-22, item (7)) prints "Ice Barrier Underlayment Required: Yes." About ice & water barrier
Impact-resistant roofing
Not required — Municipal Code § 18-22's IRC amendment list, items (1) through at least (24) (a single continuously-numbered, exhaustive sequence), was read in full and contains no UL 2218, Class 4, or impact-resistance provision anywhere; the full Chapter 18 Municode content (Building, Residential, Fuel Gas, Fire, and related articles) was also grepped for "UL 2218" and "Class 4" with no hits.
Wind design criteria
Basalt Municipal Code § 18-22 (Adoption of the International Residential Code, 2021 edition, subject to amendments), item (7), amends and prints Table R301.2(1) Climatic and Geographic Design Criteria: Ground Snow Load "55 psf"; Wind Design Speed "115" mph; Topographic effects "No"; Special wind region "No"; Windborne debris zone "No"; Seismic Design Category "B"; Weathering "Severe"; Frost line depth "36""; Termite "None to Slight"; Ice Barrier Underlayment Required "Yes"; Flood Hazards "Ord# 25 series 2000"; Air Freezing Index "2500 Deg Day (F)"; Mean Annual Temp "44°." (Verified against the Town's own June 2023 first-reading ordinance exhibit, rendered at 300dpi and read directly from the table image; the Town's Building page confirms these 2023 amendments "were approved at second reading on June 27, 2023," and the identical table is reproduced verbatim in the current Municode-codified text, Supp. No. 28, codified through Ordinance No. 08-2025.)
Sales & use tax
Basalt spans Eagle and Pitkin Counties, and the combined rate differs by which county a given address sits in: Eagle County portion, 8.20% (state 2.9% + Eagle County 1.50% + Town of Basalt 3% + Roaring Fork Regional Transportation Authority (RFTA) 0.80%). Pitkin County portion, 9.30% (state 2.9% + Pitkin County 2.60% + Town of Basalt 3% + RFTA 0.80%). Per CO DOR DR 1002 (a 2019/2020-vintage publication), Basalt is state-collected: its "State-Collected City Sales Taxes" table prints Basalt's row as "Basalt / Eagle, Pitkin / 3% / 3.33% [service fee] / None [use tax]," Eagle County's rate as "1.50%1" (footnote 1: "Rate includes 0.5% Mass Transit System (MTS) in Eagle and Pitkin Counties"), and a Pitkin-County row specifically labeled "Pitkin (in Basalt) / 2.60%1" -- lower than Pitkin County's general 3.60%1 rate elsewhere in the county. DR 1002's Regional Transportation Authority (RTA) table separately lists "Roaring Fork / Basalt and New Castle city limits / 0.80%," applicable countywide-boundary-independent since it is keyed to Town limits, not county. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
