Re: Amendment 2: Open Channel Study —Burchill Channel, Contract No. 00477
Dear Mr. Owen:
It is our understanding that the City of Fort Worth would like to utilize 2-Dimensional hydraulic modeling and stream
geomorphology to develop accurate, lower impact proposed conditions to Burchill Channel. These alternatives will be
designed on a conceptual level and will require additional analysis for construction. Several modifications will be
required to our scope in order to meet the City requests and include the following:
l . Develop Infoworks SD model of 500 ft upstream of Beach Street Culvert at file downstream end of Burchill
Channel.
a. Obtain topographic survey and build a digital ground model (TIN format) for the study area. (See
Attached Proposal from GAI)
b. The dovr�lstrearn limits of the study will be Rosedale Street to the north and Sycamore Creek to the west.
c. Delineate drainage areas and develop ultimate conditions hydrology for additional drainage areas that flow
into the study area that were not included in the original Burchill Channel Study. This includes the areas
east of Beach Street, south along Mitchell, and west along Maddox. Document methodology with
supporting exhibits to be included in the Open Channel Study report format.
d. The input hydrograph for the upstream limits of the project will betaken from the hydrology developed for
the Burchill Channel Study.
e. Develop an Infoworks SD dynamic hydraulic model including approximately 500 ft ofBurchill Channel,
the Beach Street Culvert, the storm sewer lateral running south along Beach Street, and a tvo-dimensional
(2D) surface for overflow in the project vicinity.
f. Obtain the effective hydraulic model of Sycamore Creek and perform a coincidental occurrence analysis to
develop asteady-state tailwater condition for the outfall. 'The analysis will be performed according to the
City of Fort Worth Storm Water Design Manual (2006) guidelines.
g. Provide two (2) proposed alternatives to convey existing floodwaters at the intersection of Mitchell and
Maddox.
h. Document existing and proposed conditions with supporting documentation to be included in the Open
Channel Study report format.
R:'CONrRACTS;Fort VJortMarvey-BirchilIrFrw08339 mod 42_reNised.doc
2. Perform a geomorphic field assessment of Burchill Channel at 200 foot intervals including:
a. Sampling of bed and bank material for a sieve analysis. Perform sieve and weight analysis based on
samples collected.
b. Geology of the reach assessed including rock type, bedding, degree of weathering and thickness of alluvial
soils. Bank stability and degree of existing erosion will be determined.
c. Bed and bank material evaluation and calculation, equilibrium slope calculation and reach survey channel
geometry calculations. These calculations allows for data plots to best indicate the trends for material
moving average. This will analyze the channel bottom width, channel top width and active channel depth
versus the moving average.
d. Recommendations for improvements as well as possible adverse channel effects of proposed alternatives
3. Perform a Level "A" SUE in two (2) alleys located along the proposed storm sewer at E. Davis Avenue. (See
Attached Proposal from GAI)

RE: East Davis Storm Drain System
Test Holes at Line "A" Station 1+78 and 5+10
Dear Ms. McDermott:
Gorrondona and Associates, Ina (G&AI) is pleased to submit a cost proposal for Subsurface
Utility Engineering (SUE) required for the above referenced project. This proposal is based
on information obtained from your email exhibit dated 4/14/09.
Introduction
G&AI will perform the SUE work required for this project in general accordance with the
recommended practices and procedures described in ASCE Publication C/ASCE 3&02
(Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data).
As described in the publication, four levels have been established to describe the quality of
utility location and attribute information used on plans. The four quality levels are as
follows:
• Quality Level D (QL"D") —Information derived from existing utility records;
• Quality Level C (QL"C") - QL"D" informatian supplemented with information
obtained by surveying visible above -ground utility features such as valves, hydrants,
meters, manhole covers, etc.
• Quality Level B (QL"B") — Two-dimensional (x,y) information obtained through the
application and interpretation of non-destructive surface geophysical methods. Also
known as "designating" this quality level provides the horizontal position of
subsurface utilities within approximately one foot.
• Quality Level A (QL"A") — Three dimensional (x,y,z) utility information obtained
utilizing non-destructive vacuum excavation equipment to expose utilities at critical
points which are then tied down by surveying. Also known as "locating", this
quality level provides precise horizontal and vertical positioning of utilities within
approximately 0.05 feet.
It is the responsibility of the SUE provider to perform duediligence with regard to records
research (QL "D") and acquisition of available utility records. The due -diligence provided
for this project will consist of visually inspecting the work area for evidence of utilities and
reviewing the available utility record information. Utilities that are not identified through
these efforts will be here forth referred to as "unknown" utilities. G&AI personnel will scan

the defined work area using electronic prospecting equipment to search for "unknown"
utilities. However, G&AI is not responsible for designating and locating these "unknown"
utilities.
Scoot= of Work
Based on information provided by Freese and Nichols, Inc. (F&N), G&AI has developed a
preliminary scope for the SUE work required for this project. The scope of work may be
modified, with F&N's concurrence, during the performance of the SUE fieldwork if
warranted by actual field findings.
The scope of this proposal includes Quality Level "A" test holes located where the proposed
storm drain line "A" will cross the existing sanitary sewer lines (line "A" stationing is 1+78
and 5+10).
As requested, the test holes for this projecE will be surveyed.
Locatins Procedures
G&AI will utilize its utility designating marks and the proposed utility alignments to layout
the test hole locations. GAI will establish routine/ordinary traffic control (signs, cones)
whenever required as part of our standard pricing. If non -routine traffic control measures
are required (flagman, arrowboard, barricades, etc.), these services will be considered extra
and will be invoiced at our cost.
G&AI will attempt to place the test holes outside of paved areas wherever possible. G&AI
will utilize non-destructive vacuum excavation equipment to excavate test holes at the
required locations. Once each utility is located, GAI will record the utility type, size,
material, depth to top, and general direction. Each test hole will be assigned a unique ID
number and will be marked with rebar/cap, nail/disk, or chiseled X, as appropriate. The test
hole ID number and other pertinent utility information will be placed at each test hole
location. If agreed upon, a 44nch diameter PVC pipe will be placed in each test hole for
safety. If not, the excavation will be backf lied with appropriate material and the original
surface will be restored. The backfill will be compacted in lifts by mechanical means to
prevent future settlement.
Deliverables
G&AI will prepare a test holes summary sheet along with the horizontal and vertical survey
data.

Schedule
Designating field work can commence within approximately five (5) days after receipt of
Notice To Proceed (NTP) from F&N. G&AI estimates that the locating, can be completed
in one (1) day. Test hole summary sheet along with the survey data can be prepared and
delivered within three (3) days after completion of the field work.
G&AI proposes to perform the work, as described herein, for a Lump Sum price of one
thousand, eight hundred dollars & 00l100 ($1,800.00).
We look forward to working with you on this project. Tf you have any questions or require
additional information, please contact me at (817) 4964424.

City of Fort Worth, Texas
Mayor and Council Communication
DATE: Tuesday, July 21, 2009
LOG NAME: 20AMEND2EASTHARVEY
REFERENCE NO.: **C-23662
SUBJECT:
Authorize Amendment No. 2 in the Amount of $55,958.00 to City Secretary Contract No. 37391, an
Engineering Agreement with Freese &Nichols, Inc., for the Storm Water Utility Project —East Harvey
Avenue Storm Drain System and Burchill Channel
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 2 in the
amount of $55,958.00 to City Secretary Contract No. 37391 with Freese &Nichols, Inc., thereby, revising
the total contract cost to $269,023.00.
DISCUSSION:
The Storm Water Management Program was established to reduce flooding in Fort Worth, preserve
streams, minimize water pollution and to operate the storm water system in a more effective manner to
fully comply with state and federal regulatory requirements. This will be accomplished by infrastructure
reconstruction and system maintenance, master planning, enhanced development review, and increased
public education and outreach.
On October 16, 2007, (Ordinance No. 17840-10-2007) City Council authorized the issuance and sale of
$25,000,000.00 in Storm Water (Drainage) Revenue Bonds, Series 2007, to fund a two year Storm Water
Capital project program.
Home flooding has been reported in the area of East Harvey Avenue and early investigations have
identified a collapsed and under -sized storm drain running between properties. In addition, the City also
has identified the need to perform a comprehensive study of the Burchill Channel.
A request for qualifications to provide drainage design was issued by the City in January of 2006. Twenty-
fourdesign consultants submitted statements of qualifications, including Freese &Nichols, Inc.
Freese &Nichols, Inc., was selected to study the drainage in the subject area and provide subsequent
design services for drainage improvements.
On July 15, 2008, the City Council authorized the City Manager to execute an engineering agreement with
Freese &Nichols, Inc. (City Secretary Contract No. 37391) in the amount of $197,077.00 for the design of
the East Harvey Avenue storm drain improvements and a study of the Burchill Channel.
On January 12, 2009, the City Manager administratively executed Amendment No. 1 to expand the scope
to include the now standard Open Channel Study scope of services. The amount of amendment No. 1
was $15,988.00.
During the development of the preliminary plans for East Harvey Avenue Storm Drain Improvement
Logname: 20AMEND2EASTHARVEY Page 1 of 2
Design and the Burchill Channel Study, it was identified that additional scope was required.
Amendment No. 2 will provide for Level A Subsurface Utility Engineering (SUE) in the existing alleys for
the East Harvey Avenue Storm Drain and additional modeling upstream and downstream of the originally
identified section of the Burchill Channel, requiring more survey, hydrological and hydraulic calculations,
and a geomorphic field assessment of the channel.
Freese &Nichols, Inc., proposes to perform the additional services included in Amendment No. 2 for a
lump sum fee of $55,958.00. City staff considers the fee to be fair and reasonable for the scope of
services proposed.
In addition to the contract amount, $5,596.00 is required for project management by the Transportation
and Public Works Department.
Freese &Nichols, Inc., is in compliance with the City's M/UVBE Ordinance by committing to 32 percent
M/WBE participation. The City's goal on the project is 16 percent.
This project is located in COUNCIL DISTRICT 8, Mapsco 77P and 78N.
