Certificates of Participation (COPs)
The Concept
The city makes annual payments from its existing budget — like rent-to-own for a building. Designed to avoid new taxes. No public vote required. After 20–25 years, the city owns it free and clear. The Idaho Supreme Court validated the COP structure in 2015.
Case Study
Nampa, Idaho — Recreation Center (≈90,000 sq ft core, 1994)
Investors put up the construction money. The city makes annual lease payments from its existing budget. Facility membership revenue covers those payments — and today Nampa's rec center is net-positive, returning money to the city. The 13-acre Mercy Medical site was a structured land-for-improvements exchange (the city delivered road extensions, a parking lot, and public tennis courts in return), not a free gift — a replicable template for a Twin Falls land deal with an anchor institution.
Also used by: Idaho Falls ($30M police station, 1.89% rate, 2020), Chubbuck ($15.31M municipal facilities, A+ rating), Ada County, Greater Boise Auditorium District (Idaho Supreme Court case, 2015)
What This Means for Twin Falls
COPs are the primary financing tool for TLRC — the backbone the rest of this page layers on top of. At $40M in COPs (with the remainder covered by the other sources below), annual payments of ~$2.4M represent just 2.4% of Twin Falls' $101M city budget. No voter approval needed — just 4 of 7 council votes. The Nampa rec center model proves this works specifically for Idaho recreation facilities.
