Dear Jonny,
Attached please find our Updated Analysis of the projected fiscal impact of the proposed Riviera Park
project in Ammon, Idaho.
Using conservative assumptions, we project the proposed development will contribute a net revenue
surplus of nearly $8,500 to the City of Ammon’s General Fund beginning in the first year and rising
continually thereafter. A net present value calculation of the fund balance to the City was calculated
using a 3%, 6% and 9% annual discount rates, resulting in NPV’s of $757,000, $586,000, and $463,000
respectively, over a 15‐year period. As a secondary calculation, because of the timing of property tax
revenues to the City, a modified cash flow was created. Under this scenario, the City could experience a
funding shortfall in the first few years but would recover these funds and receive positive cash flows
thereafter. The NPV’s under this scenario are also positive at $518,000, $373,000, and $271,000
respectively.
The Enterprise Funds including Sewer and Water are budgeted based on fee for service and therefore
will always have the opportunity to adjust their rates to maintain adequate cash flow. As such, these
funds were not included in this analysis.
We would be happy to meet with the City of Ammon to discuss this analysis and our findings at their
convenience.
Sincerely,
Ozzie Gripentrog
