This guide covers special districts and municipal finance from formation through dissolution. It begins with what a district is, the enabling statutes that create the categories, and the formation process where the durable decisions are made. It develops the constitutional voting framework, explaining the one-person-one-vote rule and the limited-purpose exception that permits landowner-controlled districts. It works through each financing instrument — general obligation bonds, revenue bonds, special assessments, tax increment financing, and development district structures — identifying what secures each, what approval each requires, and where each is vulnerable to challenge. It covers the federal tax conditions on exemption including private activity and arbitrage, the securities antifraud and continuing disclosure regime that governs municipal offerings despite their registration exemption, and the constitutional constraints on impairing bond covenants. It closes with governance and transparency obligations, purchaser disclosure, challenge procedure, and dissolution.
