Annual Review of Updated DIM Figures
The Development Impact Model ("DIM") was adopted by the Board of Supervisors on
October 12, 2005, following its creation by the economic consulting firm TischlerBise.
The DIM is an economic tool that the County utilizes when considering land use planning
policy decisions and rezoning applications. The DIM has been designed to project fiscal
impacts that may result with Iand use change decisions.
The Development Impact Model — Oversight Committee (DIM -OC) was created by the
Board of Supervisors in 2006 and tasked with overseeing the annual update of the figures
utilized by the Development Impact Model.
The model update occurs each year following the Board's adoption of the County budget.
It is important to note that the model itself is not modified; the model's formula and
functionality does not change. The annual update process involves County staff
gathering updated budget and capital improvement figures, along with a myriad of other
data that is utilized within the model's various formulas. This updated data is brought
before the DIM -OC for review and evaluation prior to being input into the model and
forwarded to the Board of Supervisors for their approval.
Attached is a list of the information that staff has gathered for inclusion in the DIM
update.
