1. Waiver for “Public Purpose.” The City Council may, on a project by project basis, authorize exceptions or adjustments to the Impact Fee rate structure for those projects the City Council determines to be of such benefit to the community as a whole to justify the exception or adjustment. This option is available to: (i) respond to unusual circumstances in specific cases, (ii) ensure that the impact fees are imposed fairly and (iii) exempt low income housing and other development activities from impact fees and establish one of more sources of funds other than impact fees to pay for the development activity, and (iv) induce certain development that will generate sales, tax, property tax or franchise tax in an amount sufficient to defray a fair cost of the infrastructure being provided.
