104 Analyze Infrastructure Capability to Serve "Infill" Development
The work associated with the Infill analysis is to determine if the existing
infrastructure can sustain the increased water demands until the year 2025. This
work element is to be completed as a priority item and contains portions of:
a. Task 10.1 Obtain and Evaluate Long-Term Planning Information
b. Task 10.2 Develop Long-Term Demand Projection
c. Task 12.0 Long-Term Service Development
The analysis is to be performed on the water system that is presently in place
with the exception that the water model will include the committed improvements
to serve Padre Island. The demand model will use maximum per capita day
demands.
The period of time for this analysis will be limited to the year 2025 and as such
will become a single part of the Long-Term Service Development as described in
Task 12.0.
10.4.1 Obtain and Evaluate Data. Obtain current land use planning maps for
the current service area of the City to determine the nature of infill in
each service pressure zone. Obtain recent aerial photographs of the
City to determine the current extent of development in each service
pressure zone.
10.4.2 Perform Infill Analysis. Utilizing the current land use planning maps,
determine the extent of fill-in until the year 2025. Using aerial
photography, conduct a "roof top count" and on the ground survey to
determine if current development is consistent with the current land use
plan. Using conservative growth rates that are applicable for the current
economic condition of the City's service area, project the increase in
housing, commercial, and industrial units that may occur by the year
2025. The analysis will include build out of Zone 2 and 4 and total infill
between Holly Road and Cayo East Oso. These projections should be
consistent with the City's current land use plan and not assume changes
in land use.
AMD. NO.6
EXHIBIT "A"

Where information may be lacking, assume that adjacent unused
property will develop in a similar nature to those adjacent properties
with development currently in place.
10.4.3 Large Volume Users. Simulate the addition of two additional large
volume users in the vicinity of Equistar refinery. The volume and rate of
consumption will mimic that which has been established by similar
facilities
10.4.4 Demand Generation for lnfill Analysis. Once sub-tasks 10.4.1 through
10.4.3 are complete, simulate demand patterns consistent with the land
use plan and infill analysis. This demand analysis will incorporate a per
capita demand consistent with the City's historical records. In addition,
the infill demand model will also utilize gpm per acre analysis consistent
with the City's historical records.
ThiS demand model will utilize maximum day demands to determine
water system component capability from the perspective of treatment,
transmission, storage and pumping to meet these 2025 infill demands.
10.4.5 Prepare Task Results Summary Document (see Task 27.1) and attend
Workshop NO.2. The Task Results Summary will describe the
evaluation process that was completed for the infill analysis. This
Summary will include the assumptions made in determining the infill to
the year 2025 and the effect on water demand in each of the City's
eXisting service zones.
The findings of the water system components (treatment, transmission,
storage and pumping facilities) will be presented as in each components
apparent capability to meet the infill demands. If a component is not
capable of meeting the demand, the reason for apparent failure will be
clearly presented. If a component appears to have excess capacity, this
estimate of excess capacity will be clearly presented. Incorporate City
comments into the minutes for the Workshop and into the project Report
(see Task 27.2).
10.5 Develop Long-Term Water Delivery Strategy
10.5.1 Develop up to 5 long-term water delivery strategies that define long-term
water sources, WTP capacity requirements, major transmission piping
configuration, and storage capacity/location.
