Description
of Study Area
The
area studied is primarily undeveloped with little or no water and wastewater
service to the majority of the tracts.
Multiple tracts have proposed future improvements ranging from single
family developments to commercial developments. Ronald Reagan Boulevard and Parmer Lane bisect the study
area from north to south.
Population
and Demand Projections
For
the analysis, the population projections and water demand projections in the
KFA master plans were modified to account for the current economic conditions
to determine the water demand of the study area through the year 2029. Demand information from a water model
received from KFA was then used to apportion the revised demands to the
proposed pipe network at 5-, 10- and 20-year time horizons. Wastewater loadings were determined
using a similar approach. Each
scenario was an adjustment and refinement of the KFA master plan in order to
focus the development to this specific corridor.
The
KFA projections were broken into 5-year periods and then analyzed to establish
an average annual growth rate, G, for each period. These growth rates were then adjusted taking into account
factors affecting growth, including the current economic downturn. Three (3) scenarios were determined and
presented: low, medium, and high growth.
Per conversations with the City, the medium scenario was ultimately
chosen. The table below summarizes
the medium growth scenario.

The
average annual growth factors were applied to the water and wastewater
connection projections in the KFA master plans to project future water and
wastewater Living Unit Equivalents (LUEs). Future water demand and the wastewater loadings were then
projected using 2.8 people per LUEs.
