Development Impact Calculation Software

If your area is growing, one of two things is happening:

  • The growth of infrastructure is paid for by development through the use of well-crafted and current Development Impact Fees, OR

  • There are no well-crafted and current Development Imapct Fees in place, which means the growth of infrastructure is paid for by current residents.

If you are in the second group then you need well-crafted and current Development Imapct Fees as soon as possible.

In the past you would have had to pay a consultant to come in and calculate these Development Impacts for you. But with the GSS Development Impact Software you can calculate these impacts yourself.

Watch the brief video below to get an overview of the software:
