ADDENDUM#2 TO
WATER SYSTEM REPORT
Aggieland Business Park
College Station,Texas
November 13, 2007
original report dated April 13, 2007
General Information
The purpose of Addendum No. 2 to the Water System Report for the
Aggieland Business Park is to provide information to the City of College
Station and the Brushy Creek Water District regarding the flow test that
was conducted on the newly installed water system in Phase 1 of the
Subdivision.
The two hydrants used for the flow test report are FH #3 and FH #4
shown in the construction plans for this project. These two hydrants are
located at the highest elevations of any hydrants planned in the
subdivision and therefore provide the worst-case scenario for fire flows
in the development.
Findings and Conclusion
The flow test was conducted by Kent Laza, P.E. of Civil Development,
Ltd., and Steven Cast representing the Brushy Creek Water District. The
report from the flow test is shown in Exhibit A. Data from this report
was used as input to the WaterCAD computer model to determine
maximum available flowrates at this location. The model was set up for a
demand of 1500 gpm, which is the lowest allowed by the International
Fire Code for commercial buildings. The demand was split between two
hydrants as allowed by the BCS Design Guidelines.
The results of the model are summarized in Exhibit B. They show that at
a flowrate of 1500 gpm, the minimum system pressure was 29.10 psi,
which exceeds the minimum requirements of TCEQ and the City of
College Station. It also indicates that there is additional capacity in the
system for higher flowrates if needed.

A. Building Size Restrictions
1. The size of all buildings in the Aggieland Business Park shall (Minimum

by the available fire flow in accordance with Table B105.1
Required Fire Flow and Flow Duration for Buildings) of the latest edition
of the International Fire Code. The Building Types listed in the table are
defined in the latest edition of the International Building Code. Excerpts
from the International Fire Code and the International Building Code (on
the date that these Deed Restrictions were adopted) are shown in Exhibits
A and B respectively.
Exception: A reduction in required fire flow of up to
50% is
allowed
when the building is provided with an approved au s P
system installed in accordancewith
t Stion l 3.3.ire C1 or 903.3.1.2 (or
applicable future references) of the e
e.
2. The available fire flow at each building site shall be determined through
an analysis of the water system by an engineer who is licensed to practice
in the State of Texas. The maximum available flowrate shall be the
flowrate at which the following two conditions are both met in the system
within the Aggieland Business Park and along Jones Road through the
limits of the Aggieland Business Park:
a. A residual pressure of at least 20 psi is maintained.
b. The maximum water velocity through any pipe is 12 feet
per second.

WATER SYSTEM REPORT
Aggieland Business Park
College Station,Texas
April 13,2007
General Information
Purpose: The purpose of this analysis and report is to establish the maximum flowrates that
are available to the tracts of land within the Aggieland Business Park.
Location: The Aggieland Business Park is located in the ETJ of College Station at the
intersection of SH 60 and Jones Road.
Land Use: Commercial Subdivision
Design Criteria
Primary Water Supply: Existing 10"line along Jones Road(Brushy Creek Water Supply Corporation)
Minimum Pressure: 20 psi
Maximum Velocity: 12 fps
Pipe: PVC DR-14 C909
Roughness Coeff 150(Hazen Williams)
Hydraulic Software: Haestad Methods WaterCAD v.6.0
Existing System Pressure Tests
Flow Hydrant: New hydrant on Jones Road at the future intersection of Emperial Loop and Jones
Road
Flowrate: 1187 gpm
Gauge Location: Hose bib on nearby house(approx.0.5 mi from the flow hydrant)
Static Pressure: 78 psi (180 ft water)
Residual Pressure: 50 psi(115 ft water)

Applicable Exhibits: Exhibit A—Flow Test Report
Exhibit B—Water System Schematic
Exhibit C—Computation of Max. Flowrates at Lots 7& 8
Exhibit D—Computation of Max. Flowrates within Park
Conclusion
Based on the computer model,the maximum flowrate that is available to Lot 7 &8 under the City's Design
Guidelines is 1600 gpm, and the maximum flowrate that is available within the Business Park is 2200 gpm.
It is assumed that these fire flows are not occurring at the same time. These maximum flowrates will
determine the size and type of building that can be constructed on these lots.
