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 land 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 plan 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 — "Annual Review/Update
Critical Inputs" - for inclusion in the DIM update.
Discussion regarding. Model Operations
At the previous meeting of the DIM -OC, an issue was raised regarding whether the DIM
acknowledges the real estate taxes paid by a residential use. Staff will present an
overview on the DIM's operations, and how the DIM has been applied to forecast
impacts of new development. Correspondence on this issue is attached.

Dear JP:
In response to your letter and our conversation shortly thereafter, the County has been in contact with
Tischler-Rise to better understand how the Development Impact Model (DIM) was designed, in
particular to your concerns about the school component of the model that is utilized during the rezoning
process.
The DIM was designed to forecast overall County budget implications which might result from future
land use changes over a 20 year period. In theory, the DIM could be utilized to analyze future land use
plan changes and offer a fiscal overview of the operational and capital implications of the land use plan
change, illustrating the positives and negatives of the land use plan in the Comprehensive Plan update
process. The DIM was created as a land use planning tool, and is not part of the Finance Department's
budgeting process. Additionally, the DIM was not designed as a proffer study per se, although the
output of the model is certainly valuable in assessing the capital facility fiscal impacts of a rezoning
development proposal.
In terms of the use of the DIM during a rezoning consideration, only the capital component of the DIM is
considered. Since your inquiry referenced school costs, we have reviewed the DIM capital component
that would be utilized to project capital costs associated with new residential uses.
The DIM utilizes student generation ratios, and school construction costs and design capacities, to
project potential shortfalls reflective of the additional demands for schools generated by new residential
development. The school construction costs within the model utilize those costs and projects included
in the annually adopted Capital Improvements Plan (CIP) — note that the CIP figures do not include bond
service costs. Therefore, bond service costs are not included in the DIMS output for rezoning
consideration.
The DIM projects that new residential uses will create a negative impact on school facilities. The
following chart illustrates these projected capital impacts reflective of the 2009 model:

The DIM capital component utilized for rezoning consideration looks strictly at the capital costs impact
reflective of the proposed residential housing type. Conversely, if a rezoning applicant proffers to
mitigate a projected capital impact to schools, the resulting proffered contribution would be applied
solely to school capital; impacts to operations are not relieved nor addressed.
It is important to note that the County does not maintain a policy of applying a fixed percentage of
residential real estate tax revenue toward school capital costs. The DIM's capital impacts projection is
utilized to illustrate the impacts to school capital incurred by new residential growth.
I trust you w'll find this information to be of use.
sincerely, i

In Re: DIM Review Oversight Committee; Letter from Eric Lawrence dated April 20 2010
Eric:
We appreciate your response to the DIM modeling question we posed in last year's meeting. It's a
confusing issue and has various layers of complexity regarding the DIM's use, the voluntary proffer
amounts, how the County utilizes tax revenues, and the other matters alluded to in your letter.
Not to simplify this issue, but the statement that the "DIM's capital impacts projection is utilized to
illustrate the impacts to school capital incurred by new real residential growth" is important.
Voluntary or not, the output of the DIM model is utilized extensively in binding proffer agreements
created during the rezoning process. It's critical that the model's hypothetical results are correct.
In a nutshell, every pertly of a school proffer dollar paid to the county should go to capital
improvements to schools, in other words "bricks and mortar." Right now the amount collected by
the County from proffers is insignificant, but in a few years it should cover a significant portion of
budgeted school construction costs. For example, if proffers for 600 single family homes in the
amount of $18,491 are collected annually, the total revenues to the County would be over $11
million.
In the stated example, the 600 homeowners ultimately pay the proffers through increased new home
prices at the time they purchase their homes. Those homeowners are paying to compensate for the
impact of moving into their new home in the County upfront and in fiill.
However, as you state in your letter, the County does not have a fixed source of tax revenue to fiend
capital improvements to schools, it merely utilizes a portion of on-going collected tax revenues to
pay the capital costs of construction. A homeowner who buys a house with a school proffer
incorporated in the price of the home immediately begins paying residential real estate taxes to the
County. Those taxes, in part, go toward the funding of capital improvements to schools in addition
to the up -front proffer money they have already paid to offset the impact to school capital costs. The
specific amount paid by any givenhomeowner toward school capital costs through taxes may be hard
to figure (and a reason for this exercise), but revenue from real estate taxes does get allocated to the
Eric R. Lawrence Letter
May 27, 2010
Page 2
capital construction cost of schools. As a result, a person buying a new home with a school proffer
incorporated into the price is paying twice to mitigate impacts to the school system's capital budget
caused by occupancy of the new home.
According to your letter, the County does not specifically apply a fixed percentage of residential real
estate tax revenue toward school capital costs. If there's no mechanism to calculate the amount of
tax dollars a property owner pays toward capital improvements, there can be no way the DIM can
calculate a "credit" for the taxes paid by the property owner to offset the "debit" paid by way of the
proffer on the property. Persons purchasing a new house with a school proffer are paying the proffer
without an offset to account for their ongoing payment of real estate taxes.
This situation creates an imbalance where a new homeowner pays the impact cost up front, but still
gets an annual bill for the principal and interest cost of school construction via taxes. There has to
be an offset in the model or in the taxes that person pays. Otherwise, the DIM does not accurately
account for impacts to the County's capital budget, which is the point of the model to begin with.
Additionally, we note that the scenario regarding school proffers can be applied to any capital costs
for which the DIM calculates an "impact" that is off -set by a proffer and for which a portion of taxes
collected by the homeowner also fiends on an on-going basis.
As we understand the function of the DIM Oversight Committee, it is to determine whether the
inputs used in the model are accurate and appropriate. It is our belief that unless the inputs include
credits for real estate tax revenues the inputs are faulty.
We believe the issues raised in this letter deserve a thorough review by the DIM Oversight
Committee. We hope the staff will be able to clarify this concern.
Respectfully submitted,
J. P. aIr
