The incentive is tied specifically to the difference between the property’s base assessed value and its post-development assessment. The stipulated base assessed value of the property under the agreement was $71,439. The current assessed value is $16,926,992, resulting in an increase of $16,855,552.86. At the county’s real estate tax rate of 75 cents per $100 of assessed value, that increase generates an annual performance incentive grant of $126,416.65. Smith urged supervisors to remember that they represent county residents, not corporate shareholders, and said opposition to the project has been unfairly characterized.
