Impact Fees


In order to implement an equitable Development Impact Fee system for the City Capital Facilities, and to re-evaluate our current methodology of calculating impact fees, the City retained an Impact Fee Consulting Firm to prepare an Impact Fee Study. In accordance with Idaho Code, the Development Impact Fee Study was based on actual System Improvement costs or reasonable estimates of such costs.

In addition, the Development Impact Fee Study uses a fee calculation methodology that is net of credits for the present value of revenues that will be generated by new growth and development based on historical funding patterns and that are anticipated to be available to pay for System Improvements, including taxes, assessments, user fees, and intergovernmental transfers.

The Amended Development Impact Fee Ordinance No. 4420 has been passed and adopted by the Council of the City of Nampa on March 4, 2019 and shall become effective July 2, 2019. With this amended adoption, all development impact fees will be calculated utilizing the table found in the link below.
