FIRE FLOW REPORT
EXISTING WATER SYSTEM SUMMARY
The subject development is located on the west side of the Texas Avenue south of the intersection of Texas
Avenue and University Drive. The subject property sits between Texas Avenue to the east and Meadowland Drive
to the west. Currently, an 8" City of College Station (CS) waterline is located along east side of Meadowland
Drive and a 12" CS waterline is located along the Texas Avenue frontage. The 8" waterline is in the process of be
replaced with a 12" waterline that will begin at the 12" waterline on Texas Avenue and continue east -west through
the Knights Inn property north of the subject tract, and continue north/south along Meadowland until looping back
around to the 12" waterline on University Drive.
There are three existing fire hydrants along the 12" waterline on Texas Avenue near the subject property as shown
in Exhibit A — Water System Layout. Fire Flow data has been made available from the city and is included in
Exhibit B — Fire Flow Test Data.
Additionally, there are two existing fire hydrants and one proposed fire hydrant along Meadowland Drive. E( xhibit
A — Water System Layoutl. No flow data is available for these hydrants.
PROPOSED WATER SYSTEM IMPROVEMENTS
An adjacent development, Northpoint Crossing Development (NPC), proposes to replace the 8" waterline that
begins at the 12" waterline on Texas Avenue north of the Knights hm, and continues east -west on the north side of
the Knights Inn property north of the subject tract, and then continues north/south along Meadowland until looping
back around to the 12" waterline on University Drive. The approved drawings for the NPC development propose a
12" waterline to replace the 8", including adding a fire hydrant (FH #2) on Meadowland Street within the Home2
Suites property boundary.
REQUIRED FLOW
2012 International Fire Code (IFC) and CS commercial minimum required = 2,625 gpm (split between 3-hydrants)
The existing hydrant #1, the proposed hydrant #2 (by others), and the existing hydrant #3 located along
Meadowland Drive will serve as the 3-hydrants needed to supply a total flow of 2,625 gpm to the subject property.
ANALYSIS
For purposes of hydraulic analysis, EPANET Version 2.0 by the U.S. Environmental Protection Agency was used
for the water system model. To properly calibrate the water system model, fire hydrant flow tests were requested
and obtained from CS Utilities for the existing hydrant at 104 Texas Avenue South (A-032) and an existing hydrant
at 320 Texas Avenue South (A-035) on the 12" waterline along Texas Avenue. Refer to Exhibit B — Fire Flow
Test Data. Using this data for flow, static and residual pressures, a water system model was created and calibrated
for this small portion of the existing water system.
Two separate analyses were performed, one the existing conditions and the other on the proposed conditions based
on city approved drawings for the NPC development. The proposed improvements include replacing an existing
8" waterline with a 12" waterline as designed in the NPC development with one (1) new fire hydrant (FH#2) and
associated appurtenances were added to the water model and then analyzed for minimum pressure and maximum
velocities in the system.
RESULTS
To obtain the 2012 International Fire Code (IFC) and CoCS minimum required Fire flow of 2,625 gpm, the
EPANET model was ran with the following fire flow scenarios:
Existing Conditions
- Fire flow scenario 41: Three hydrants flowing 1,000 gpm each. The three hydrands include FH# 1 and
FH#3 located on Meadowland St. and FH A-035 located on Texas Avenue.
- Fire Flow Scenario 42: One hydrant flowing 2,625 gpm. This was modeled using FH A-035 located on
Texas Avenue.
- Fire Flow Scenario #3: One hydrant flowing 2,625 gpm. This was modeled using FH 41 on Meadowland.
- Fire Flow Scenario 44: Static conditions, no flow.
Proposed Conditions
- Fire flow Scenario #1: Three hydrants flowing 1,000 gpm each. The three hydrands include FH# 1, FH#2,
and FH#3 all located on Meadowland Street.
- Fire Flow Scenario #2: One hydrant flowing 2,625 gpm. This was modeled using FH #2 located on
Meadowland Street.
- Fire Flow Scenario #3 is the static conditions with no flow.
The resultant node pressures and velocities are documented in Exhibit C — System Analysis.
The proposed water system improvements and existing infrastructure, under the three fire flow scenarios described
above, were determined to adequately meet or positively exceed the minimum 2012 IFC and CS Design Standards.

EXISTING WATER SYSTEM SUMMARY /
The subject development is located on the west side of the Texas Avenue south of the intersection of Texas
Avenue and University Drive. The subject property sits between Texas Avenue to the east and Meadowland Drive
to the west. Currently, an 8" CoCS waterline is located along east side of Meadowland Drive and a 12" CoCS
waterline is located along the Texas Avenue frontage. The 8" waterline is in the process of be replaced with a 12"
waterline that will begin at the 12" waterline on Texas Avenue and continue east -west through the Knights Inn
property north of the subject tract, and continue north/south along Meadowland until looping back around to the
12" waterline on University Drive.
There are three existing fire hydrants along the 12" waterline on Texas Avenue near the subject property as shown
in Exhibit A — Water System Lay. Fire Flow data has been made available from the city and is included in
Exhibit B — Fire Flow Test Data.
Additionally, there are two existing fire hydrants and one proposed fire hydrant along Meadowland Drive. (Exhibit
A — Water System Layout). No flow data is available for these hydrants.
PROPOSED WATER SYSTEM IMPROVEMENTS
The subject development does not propose any additional improvements.
REQUIRED FLOW
City of College Station commercial minimum required = 2,625 gpm (split between 3-hydrants)
The existing hydrant #1, the proposed hydrant #2 (by others), and the existing hydrant #3 located along
Meadowland Drive will serve as the 3-hydrants needed to supply a total flow of 2,625 gpm to the subject property.
ANALYSIS
For purposes of hydraulic analysis, EPANET Version 2.0 by the U.S. Environmental Protection Agency was used
for the water system model. To properly calibrate the water system model, fire hydrant flow tests were requested
and obtained from CoCS Utilities for the existing hydrant at 104 Texas Avenue South (A-032) and an existing
hydrant at 320 Texas Avenue South (A-035) on the 12" waterline along Texas Avenue. Refer to Exhibit B — Fire
Flow Test Data). Using this data for flow, static and residual pressures, a water system model was created and
calibrated for this small portion of the existing water system.
The proposed improvements of the 12" waterline as designed in the Plaza Redevelopment with one (1) new fire
hydrant (42) and associated appurtenances were added to the water model and then analyzed for minimum pressure
and maximum velocities in the system.
RESULTS
To obtain the CoCS minimum required fire flow of 2,625 gpm, the EPANET model was ran with two fire flow
scenarios using the hydrants along Meadowland Drive. Fire flow scenario #1 was 1,000 gpm from each of these
three hydrants and fire flow scenario #2 was modeled as 2,625 gpm from the fire hydrant #2. The resultant node
pressures and velocities are documented in Exhibit C — System Analysis.
The proposed water system improvements and existing infrastructure, under the three fire flow scenarios described
above, were determined to adequately meet or positively exceed the minimum B/CS design standards.
