Impact Fees, where do we stack up?

I have had several questions about impact fees. I thought that I would begin to put a few of the facts out there so that everyone can make informed decisions.

All of this information is backed up by several public sources. Feel free to verify any of it for yourselves:
1 Tennessee Advisory Commission on Intergovernmental Relations, Issue #9, April 2002
2 U.S. Census Bureau, Census 2000
3 Various city departments

Okay, let the games begin:
(I will make this very easy to calculate and relate to existing homes. These numbers have been formed into reflecting a $200,000 home in each stated community. This is on a per home basis. Every Planning Commission the city will give you the total number of homes etc. so these numbers would be multiplied based on the latest city permit numbers. I hope that all makes sense.)

***an increase of .25 per square foot would increase revenue $500 per permit.
***an increase of .35 per square foot would increase revenue $700 per permit.
***an increase of .50 per square foot would increase revenue $1000 per permit.

I'll let you do the math from here. By increasing the impact fee, where does that place us in relationship to say....Franklin and Fairview? Now that we do not have a property tax (which is fantastic) where is the city going to come up with a little extra cash to improve those things that will need improving in the coming years? Impact fee evaluation might be a good start.

What do you think???
