the City shall be applied according to the CIP as shown in the funding plan in the
Joint Transportation Study (JTS)_9r as mpdied by amendment tg_thiragi;eement_
and summarized in Attachment C-l. The annual parking tax revenue projections
for both Portowned lots and private lots were forecast for the next ten years in a
study prepared by Berk and Associates.  This revenue forecast, including the
parking tax revenue projections and each party's nancial commitments to
particular CIP projects, is described in Attachment C-1 and Attachment C-2.
Based on the projections in this study, the parties agree to allocate the actual
parking tax revenues between the parties to fund the CIP projects in the following
percentages through the term of this ILA. The amount of funds dedicated toJE
South Access Connecting 2807241" Avenue South South "( Sti'eetRourLdabout
and SR 518 projects shall be 22% of the actual revenues with the following
limitatiopg, but-Hemp more than $5 million; can be spent on the SR 518 project,

remaining percent of actual revenues, 63.1%, shall be applied to all other City CIP
projects as noted in the JTS or CIP list.

In addition, if the actual revenues fall short of the forecasted revenues over
a two year period, then the parties shall pursue the following options to correct
parking tax revenue shortfalls:
a.  Actual Revenues Are 90% or less of the Forecasted Revenues  If the
actual revenues are 90% or less of the forecasted revenues during a two
year period, then the parties are responsible for modifying the CIP
projects planned for the two year time period to t within the individual
CIP budgets identied in Attachment C-l. Alternatively, if the parties
agree, the parking tax may be raised so that the amount of the parking

Page 3

tax  collected  by  the  City  meets  the  sum  of  forecasted
revenue. However, if the parties agree to raise the parking tax to
generate sufcient funds to meet the amount of forecasted revenue, the
new parking tax rate shall not generate revenue to exceed the JTS
project lnding requirements shown in Attachment C-l.

b.  Actual Revenues are  greater than 90% but less than 100% of the
Forecasted Revenues - If the actual revenues are greater than 90% but
less than 100% of the forecasted revenue for the twoyear period, then
the parties will be responsible for modifying their respective projects to
t within the individual CIP budgets identied in Attachment C-l.
Under these circumstances, the parties agree that the parking tax should
not be raised. 2008 shall be the rst year that this corrective action can
be implemented.

c.  The parties may agree to use a combination of options a and b.

(1.  Adding or Deleting Projects from the CIP project list:  Either party may
request that a project be added or deleted from the list of projects in the

addition or deletion shall address these concerns. If the party seeking
addition or deletion of a project addresses these concerns adequately,
then the parties shall express their agreement through a letter that
describes those conditions and then add or delete the project from the
CIP list through_an amegintegtj)_tllis_ggreenlept. If the parties cannot
agree about whether or not a project should be added to or deleted from
the list, then the parties shall engage in Dispute Resolution provisions
