May 28, 1987
TMB Contract No. ,55- 7/40 30
STATE OF TEXAS Texas Water Development Board
COUNTY OF TRAVIS and
The City of Lubbock, Texas
This Contract and Agreement, made and entered into between the Texas
Water Development Board, hereinafter referred to as the Board, Austin, Texas,
and the City of Lubbock, Texas, hereinafter referred to as the City, under
which the following terms, conditions, and provisions have been agreed upon,
in consideration of the mutual promises and covenants hereinafter stated,
WITNESSETH:
I. PROJECT DESCRIPTION AND SERVICES TO BE PERFORMED BY DISTRICT
As a joint and cooperative undertaking with the Board, to be financed
jointly as hereinafter specified, the City will develop a flood protection
plan for the southern portion of the City's playa lake systems. The
substantive content of said activities shall be in strict accordance with
requirements of the Texas Water Code, Chapter 15; associated rules of 31 Texas
Administrative Code, Chapter 355; Attachment A (original grant application
dated January 27, 1987) and Attachment B (Addendum No. 1 to the grant
application, dated February 17, 1987) which, except where indicated in the
Contract, are made a part of this Contract for all purposes; and with the
following procedures and project descriptions:
1. It shall be the responsibility of the City to establish formal and
direct liaison with the City and County Floodplain Administrators
and appropriate project directors of the U.S. Army Corps of
Engineers and the U. S. Soil Conservation Service for the purpose
of coordinating the work of the planning study and to acquire
available data pertinent to the planning effort. The planning
study shall be coordinated with all relevant flooding and drainage
protection studies and activities, which shall also be reviewed as
information for this planning project. It shall also be the
responsibility of the City to solicit comments from the general
public as to the content of the flood protection planning project.
2. The planning area for assessment of flood damage abatement measures
will be the southern portion of the City's playa lake systems (see
Geographical Area for Planning, Page 3 of Attachment A, and map of
planning area in Attachment B). Hydrologic conditions upstream of
the planning area may be considered as necessary to accurately
simulate conditions in the designated planning area.
3. The City will develop a comprehensive flood protection plan for the
planning area. The flood protection plan will be developed to the
extent possible to enhance the flood protection of the entire
watershed in which the project is located. The developed flood
protection plan will be coordinated with existing plans and
policies of the City, the county, and the state. The plan will
utilize, as at least one measure in the analysis of alternatives,
the Corps of Engineers "preventable damages" concept.
4. This plan will be developed in two phases.
A. Phase One will consist of the following activities:
(1) The City will determine drainage area characteriptics of
playa lakes in the planning area.
(2) The City will determine the storage volume of playa lakes
in the planning area.
-2-
(3) The City will determine overflow rating curves for playa
lakes in the planning area.
(4) The City will prepare and deliver to the Board a sumary
report describing the activities and results of the Phase
One program.
B. Phase Two will consist of the following activities:
(1) The City will model the hydrology of playa lake systems in
the planning area. As a part of this analysis, the City
will estimate high water level elevations at each playa and
compare them with the results of the U.S. Army Corps of
Engineers High Flood Hazard Study.
(2) The City will develop alternate flood protection management
plans for the playa lake systems in the planning area.
(3) The City will evaluate structural and non-structural flood
protection alternatives for the planning area.
(4) The City will evaluate controls and automation for playa
lake system storage and water transfer.
(5) The City will perform a benefit -to -cost analysis for all
flood protection measures proposed. Cost estimates will be
based on current (1987) prices. Cost estimates must
include the investment cost (first cost plus interest
during construction) and annual costs (interest,
amortization, and operation and maintenance). An
assessment will be made of flood protection benefits to be
expected from implementing the proposed flood protection
alternatives, including non -monetary benefits such as
reduction in hazards to human life and safety.
-3-
(6) The City will investigate the implementation of all
proposed alternatives, including the priority of
implementation. An estimated schedule and budget for
implementing alternatives will be developed.
(7) The City will prepare and deliver to the Board a draft
Final Report for review. Following review of the draft
report by the Board, the City will deliver to the Board a
Final Report.
II. PROJECT SCHEDULE AND REPORTS
The City has 90 days, beginning April 16, 1987, to execute this Contract
and to provide written evidence acceptable to the Executive Administrator that

III. PROJECT DESCRIPTION
A. Geographical Area For Planning:
The area to be included in the proposed flood control study
includes playa lakes located in the City of Lubbock, Lubbock
County, Texas. Attachment 1 is a copy of a Flood Insurance
Rate Map (FIRM) which identifies each of the following lakes
and lake systems.
om System E-1 Playa Lakes 37, 31, 27, 26, 25,
24, 23, 19, 20 and 21
System E-2 Playa Lake 22
Others Playa Lakes 30, 29, 28, 91, 17 and 18
System E-1 begins Southwest of the City approximately one
mile west of West Loop 289 at playa Lake 37. This system
then drains east into the city through nine other playa
.. lakes and east out of the City into the north fork of the
Double Mountain fork of the Brazos River.
System E-2 begins with playa Lake 22 in the vicinity of 60th
�" Street and Elgin Avenue. This system drains into playa 23
and into System E-1.
r— Other lakes to be studied include playa Lakes 30, 29, 28,
and 91. These lakes drain from Slide Road and 77th Street
south to playa Lake 91 in the City's Lakeridge development
area.
Finally, the study will include playa Lake 17 at South Loop
289 and U.S. 87 and playa Lake 18 located near 50th Street
and Avenue A.

B. Description of Existing Hazard
The project is needed to accurately and efficiently deter-
mine means to alleviate flooding of the southern portion of
the City of Lubbock's playa lake systems. The largest sys-
tem (System E-I as portrayed by attached FIMA map) currently
poses the most significant flooding hazard.
Statement of Problem
When water from storm runoff reaches the high water
(overflow) elevation at Lake #26, several streets and high-
ways are under water and must be closed to traffic. These
streets are: Quaker Ave. west of Leroy Elmore Park, 64th
Street north of the park, Peoria Ave. east of the Park and
Loop 289 access roads south of the Park.
Loop 289 was constructed through the lake area. The main
lanes of Loop 289 were elevated with 8 - 8'x4' box culverts
OM to provide for the overflow. The bulk of the overflow will
pass over the access roads of the Loop and these access
roads were constructed below the overflow elevation. Twelve
24" pipes exist below the access roads.
Quaker Avenue was aligned to skirt the edge of the lake, but
parts of Quaker Avenue were constructed below the overflow
elevation.
Quaker Avenue and Loop 289 is an integral part of the City's
traffic -carrying system. Traffic must be detoured around
the lake area during high water conditions placing addi-
tional burdens on other streets and thoroughfares.
A public library was constructed in the park area and is in-
accessible during periods of high water.
The City has experienced more flooding in the past few years
due to more frequent rain fall and reduced percolation re-
sulting from a rising water table. These factors have
caused the lake to remain nearly full almost continually.
Even small amounts of rainfall cause major problems since
there is little holding capacity available in the lake.

Additional Information
•- Lake 26 receives overflow from lakes upstream and overflows
Southerly to Lake 25. A study conducted by the Federal
Emergency Management Agency projects the overflow for a 100-
r year frequency storm to be 470 cubic feet per second from
Lake 26. Using a developed runoff condition for the entire
drainage area, a local engineering firm projects a 100-year
overflow of840 cubic feet per second.
The primary drainage system of Lubbock is overland, surface
flow to the playa lakes. We respect the individual drainage
areas of the playa lakes but provide for overflow from one
to another when an overflow condition is projected. There
are very few storm sewers in the City and those that exist
primarily have outlets in the Yellowhouse Canyon on the
north and east sides of the city. The terrain is very flat
with a normal curb & gutter grade of approximately 0.2% but,
out of necessity, some curb and gutter has been constructed
with as little as a 0.1% grade.
The proposed engineering study would investigate ways to
prevent future flooding of this and other Lubbock playa lake
systems.
C. Brief Description of Methods and Procedures
The methods and procedures to be used in the development of
the flood protection plan are itemized in Section III-D,
which contains the proposed scope of work, work schedule and
budget. The proposed scope of work includes cost estimate
calculations for various flood control options as well as
cost -benefit analyses for these options. A review of the
cost -benefit analyses will show the economic viability of
the various flood control options.
The proposed project will be a study of only the playa lakes
in the southern portion

of the City of Lubbock. The infor-
study, however, will be generally
of playa lakes in the Lubbock vicin-
