EXECUTIVE SUMMARY
Approve Change Order No.2 to the agreement between Collier County and Van Buskirk,
Ryffel and Associates Inc. for the development of the Collier Interactive Growth Model
(CIAGM) for the East of County Road 951 Infrastructure and Services Horizon Study
OBJECTIVE: To increase the scope of work to allow for the CIAGM land use modeling to be
utilized by AIM Engineering & Surveying, Inc., the consultants for the Transportation Division
to update to the Long Range Transportation Plan (LRTP).
CONSIDERATIONS: On September 26, 2006, Agenda Item 16A2, the Board of County
Commissioners approved an agreement with Van Buskirk, Ryffel & Associates Inc., for the
development of the Collier County Inter-Active Growth Model (CIAGM). Since that date, staff,
in conjunction with the East of CR95 I Horizon Study Master Committee, has been working with
the consultants to establish the CIAGM. During the Transportation Division's presentation to
the Horizon Study Master Committee in December 2007 and January 2008, staff began to
discuss the potential of utilizing the land use modeling output of the CIAGM for the
Transportation Division's update to the LRTP. The updating of the LRTP requires that
assumptions be made regarding land use changes that will transpire over time to determine the
capacity of the future network. During a February 4, 2008 meeting with Comprehensive
Planning and Transportation staff and the two consultants, Van Buskirk, Ryffel & Associates
Inc., and AIM Engineering & Surveying, Inc., it became known that the two consultants had
worked together in the past under the same arrangement for the City of Cape Coral. The
CIAGM consultants had provided the land use modeling for the update of the Cape Coral Long
Range Transportation Plan.
The utilization of a consistent land use modeling within the LRTP and the CIAGM is beneficial
for increased consistency between the two long range planning tools. In order to utilize the land
use modeling output of the CIAGM by the LRTP, a modification to the CIAGM scope of
services is required. That proposal is attached as Exhibit "A". The change in scope of work will
require an additional $54,000 to the original $200,000 contract amount. Since the contract is
funded from MSTD Fund (111), a FY 08 budget transfer from Gas Tax Fund (313) to MSTD
General Fund (111) will be necessary to offset the change order.
FISCAL IMPACT: If the $54,000 change order is approved, a FY 08 budget amendment
transferring budget from Gas Tax Fund (313) to MSTD General Fund (III) will be necessary.
GROWTH MANAGEMENT IMPACT: Approval of the proposed change order will allow for
consistency within the CIAGM and LRTP which are directly related to the determination of
future long term infrastructure needs.
RECOMMENDATION: That the Board of County Commissioners:
I. Approves Change Order No.2 to the agreement between Collier County and Van

Re: Proposal to Collier County for additional services to incDrporate 90 additional Traffic
Analysis Zones (TAZ) into the Collier Interactive Gro'wth Model (CIGM) and format
data for input for the Collier County Traffic Model.
Dear Michacl:
Overview
This is in response to your request, and OUT proposal to incorporate 90 new T AZs into
the current 250 TAZs for the ClGM and to format data for input into the Collier County
Traffic Model. Additional data will include the forecasted number of vchicles per
household and percent of seasonal households. Activitics will include parcel queries for
the baseline data and thc build-out sccnario. Data input for 90 screens, demographic data
for the up to 90 data screcns and the distribution of devclopment over time to build-out.
Also, the integration of the CIGM sub-models and the facilities serics for the additional
90 T AZs. Proposal tasks include the following:
TASK 1
Baseline Data
The Consultant will develop the current ycar baseline data for current development
for the new 90 TAZs that can be updated annually. GIS will overlay thc ncw TAZs for
querying the parcels in each T AZ. Each new T AZ will be inventoried for current
development such as housing unit by type, population characteristics, and retail space by
building area, and employees, office/services, and industrial and wholcsale uses, by
building area and employees. Also to be included are school plants and enrollment,
public parks and other data considered relevant. Upon completion ofthe cell data and

cell delineation, it will be incorporated into the ClGM. Data will be entered for each
T AZ into the computer program for export to the main spreadsheet for processing.
Work product: SoUware application and data input for the new 90 TAZ8 for baseline
data for export to main sprcadsheet.
TASK 2
The 8uild-out Sceuario
The Consultant will develop a build-out scenario for each new TAZ such as housing
wlit by type, population characteristics, and retail space by building area, and employees,
office/services by building area and employees, industrial and wholesale by building area
and employees, school plants and enrollment, public parks, and othcr data considered
relevant. Each new T AZ will be inventoried using the baseline data template. The build-
out scenario will be developed for each TAZ from the parcel queries and the FLUM.
Work product: Software application and data input for the new 90 TAZs for the
build-out scenario for export to main spreadsheet.
TASK 3
Population Distribution
This task is the distribution of the population for each new TAZ over time in 5-year
intervals. From the information derived from the previous tasks, a computer
programming has been developed that is population driven, and is based on the
Population Forecast Mode! and interfaces with the sub-models devcloped to calculate the
needs and demands of the popLdation for housing units, commercial and services (in
building square footage), industrial building square footage, recreation uses in acres,
school plants and institutional uses.
In order to determine the spatial distribution of population growth and their needs,
including the location of water and sewer lines, GIS will superimpose them over the base
map with the incorporated new T AZs delineated. Growth generators such as water and
sewer mains, collectors, major and minor artcrial roadways, as well as the characteristics
and location of current development, will be inventoried tD develop gravity models,
biological models and coefficients for the spatial distribution of growth, ovcr time, to
build-out.

The spatial distribution of growth wi\1 be documented by five-year incrcments to
build-out for each new T AZ in the ACCESS computer model. Data from the CIGM can
be used to provide data for the traffic forecast and for planning.
Work product: Integration of data input, population forecast, growth coefficients and
distribution of the population by T AZ's, by five-year increments to build-out, including
additional data for the traffic models.
TASK 4
Demol!ranhic Model
This task is the demographic model, which useS regression analysis to determine the
household size, vacancy rates and percent of the population in elementary, middle, and
high school for each of the new T AZ' s. It will provide the forecasted demographic
information over time for each ncw T AZ. Additional data is needed for the traffic models
for all T AZs such as vehicles pcr household
Work product: Demographic characteristics for each new TAZ over timc, to determine
the demand for commercial facilities, (rctail, office and service) school age (elcmentary,
middle and high school), industrial, fire/ems, police, parks and hotel/motel. Additional
data is necdcd for the traffic models for all T AZs such as vehicles per household.
TASK 5
Criteria and Standards. Sunnlv Models
For forecasting future facilities, this task wi\1 apply, standards and levels of serviccs
(as applicable) for neighborhood, community and regional commercial facilitics, school
plants, fire stations, police, parks, and their timing and location. Thcse are the supply
models to meet the needs of the demand models for thc new TAZs.
Work product: Timing and location ofland uses and facilities described above.
