SCOPE FOR ENGINEERING DESIGN
The scope set forth herein defines the work to be performed by Halff Associates, Inc. (Halff) in
completing the project. Both the City of Pearland (City) and Halff have attempted to clearly define
the work to be performed and address the needs of the Project. Under this scope, Halff is expanded
to include any sub -consultant. including surveyor, employed or contracted by the Halff.
OBJECTIVE
The project area to be improved includes the section of Wagon Trail Rd. from Broadway (FM518)
to Bardet Rd. as well as Cantu Rd. and Ochoa Rd. from Wagon Trail Rd. to their respective ends
approximately 650 LF east of Wagon Trail Rd. The drainage area includes approximately 34.1
acres south of W Broadway St. The existing drainage system consists of roadside ditches, which
drain the area west to Wagon Trail, north to W Broadway, and then east toward the Corrigan Bypass
ditch, which is the outfall. The area has a history of flooding and numerous instances of street and
structural flooding have been reported.
In January 2016, Halff Associates, Inc. was authorized by the City of Pearland (City) and Brazoria
Drainage District No. 4 (BDD4) to conduct a drainage study of the area surrounding Wagon Trail
Rd. as part of Phase I of the Master Drainage Plan, which is currently in progress. The study
evaluated the drainage patterns in the area, proposed potential improvement alternatives, and
made recommendations for drainage improvements. The final report was submitted to the City in
May 2016. Based on the report, the City has requested that Halff prepare a proposal for the design
of storm sewer and street improvement to Wagon Trail, Ochoa, and Cantu Rd.
The proposed design will include approximately 3500 LF of storm sewer improvements and 3200
LF of street improvements as well as associated utility relocation and necessary mitigation. Plan
submittals will be provided at the 60, 90, and 100 -percent milestones. The improvements will outfall
into the Corrigan Bypass ditch, which is within BDD4 jurisdiction. As such coordination with BDD4
will be required. City and BDD4 permitting requirements are included in this design proposal. In
addition to construction documents, including plans, specifications, and estimates, a drainage report
detailing the design analysis and outfall location recommendations will be provided. Any easement
documents needed for the construction of the project will be prepared by Halff. The scope will also
include meetings and coordination with the City and the residents within the project area if needed.
The final (100%) design submittal is expected to be complete within 8 months of an executed
contract and written notice to proceed.

b) Perform field surveys to collect horizontal and vertical elevations and other
information needed for the design and preparation of plans for the project.
Information gathered during the survey shall include topographic data, utilities as
required by the SUE, structures, and other features relevant to the final plan sheets.
Existing drainage at intersections will be verified by field surveys. Spot elevations will
be shown on intersection layouts with cross slope to fit intersecting grade lines.
c) Determine the ROW location for the project based on approximate method. Property
corners will be located and deed research conducted for those properties which will
require easement acquisition.
d) The minimum survey information to be provided on the plans shall include the
following:
i. A Project Control Sheet, showing ALL Control Points, used or set while
gathering data. Generally on a scale of not less than 1:400:
ii. The following information about each Control Point;
1. Identified (Monument #8901, PK Nail, 5/8" Iron Rod)
2. X, Y and Z Coordinates, in an identified coordinate system, and a
referred bearing base. Z coordinate on preferred datum.
3. Descriptive Location (Ex. Set in the centerline of the inlet in the
South curb line of North Side Drive at the East end of radius at the
Southeast corner of North Side Drive and North Main Street).
3) Subsurface Utility Engineering
a) Halff will perform Subsurface Utility Engineering (SUE) in accordance with ASCE
CI/ASCE 38-02 "Standard Guideline for the Collection and Depiction of Existing
Subsurface Utility Data." This standard defines the following Quality Levels:
i. Quality Level -A: Precise horizontal and vertical location of utilities obtained
by the actual exposure (or verification of previously exposed and surveyed
utilities) and subsequent measurement of subsurface utilities, usually at a
specific point. Minimally intrusive excavation equipment is typically used to
Corrigan Ditch Sub -basin of Mary's Creek
Drainage Improvements
4 of 11 D21. Revised 7/08
minimize the potential for utility damage. A precise horizontal and vertical
location, as well as other utility attributes, is shown on plan documents.
ii. Quality Level -B: Information obtained through the application of
appropriate surface geophysical methods to determine the existence and
approximate horizontal position of subsurface utilities. Quality Level -B data
should be reproducible by surface geophysics at any point of their
depiction. This information is surveyed to applicable tolerances defined by
the project and reduced onto plan documents
iii. Quality Level -C: Information obtained by surveying and plotting visible
above -ground utility features and by using professional judgment in
correlating this information to Quality Level -D information.
iv. Quality Level -D: Information derived from existing records or oral
recollections.
b) Quality Level -A: Utility Test Holes / Utility Location (Vacuum Excavation) — Halff will
perform up to ten (10) Quality Level -A Utility Test Holes for this project. Halff will
excavate an 8" x 8" test hole, record the depth of utility, backfill & compact test hole,
and restore the surface to its original condition. An iron rod with cap, nail with ribbon
or "x -cut" will be set to mark the location of the test hole. Halff will make a good faith
effort to locate all utilities, but shall be compensated for work performed even if the
utility is not located.
c) Quality Level -B: Utility Designation— Halff will designate the approximate horizontal
position of toneable utilities within the project limits using geophysical prospecting
equipment and mark using paint and/or pin flags. We anticipate the designation of
approximately 13,000 linear feet of utilities including buried communication, electric,
gas, water and waste water / sanitary sewer. Designation of irrigation lines, storm
drain and adjacent utilities within the corridor is not included in this proposal.
Because of limited utility record information, Halff cannot guarantee that all utilities
will be found and marked within the project limits.
d) Quality Level -C: Utility Survey & Mapping — Utility paint markings, pin flags, and all
above ground utility appurtenances will be surveyed and tied to supplied project
survey control. Survey data will be processed and drawings depicting the findings of
the SUE investigation will be supplied to client in either MicroStation or AutoCAD.
e) Quality Level -D: Utility Records Research — Available utility records will be provided
to Halff by the City of Pearland. Halff will perform utility record research as needed to
successfully complete the project. Situations where the utility does not have a
metallic composition; a metallic tracer line attached; limited access to insert a tracer
line within it, the approximate location of the utility may be determined through the
use of available utility records and direct correspondence with the utility service
provider if available. In these areas, the utilities will be depicted as to utility records
Quality Level -D.
f) SUE Deliverables / CADD — Deliverables for the designating work will include an
electronic file (MicroStation and/or AutoCAD format) containing the horizontal
locations of the utilities. The utilities will be referenced into the base / seed file
provided. A Test Hole Data Form will be completed and submitted to the City for
each hole performed indicating depth, size, and material of utility. Electronic files will
also be provided in MicroStation and/or AutoCAD format along with PDFs.
g) Traffic Control - Provide routine/ordinary work zone traffic control consisting of traffic
cones and free-standing signage for this project. It does not include lane closure(s),
flagger person(s), arrow board(s), changeable message board(s), or the preparation
of engineered work zone traffic control plans. If unique or additional work zone traffic

Drainage Improvements
5 of 11 D21. Revised 7/08
control situations are required once test hole locations are determined, HaIff will
prepare a Supplemental Agreement and submit for approval.
h) Permitting — ROW and street cut permits will be coordinated with City of Pearland
4) Geotechnical Investigation
a) Soil investigations, including field and laboratory tests, borings, related engineering
analysis and recommendations for determining soil conditions will be made. In
addition to the above investigations, borings and appropriate field and laboratory
analysis will be made at reasonable intervals along the project alignment for the
Contractor's use in determining soil conditions for preparing bids and a Trench
Safety Plan. Approximately four (4) borings will be taken.
b) Prepare a detailed geotechnical engineering study and pavement design
recommendations. The study shall include recommendations regarding utility
trenching and identifying existing groundwater elevation at each boring.
ASSUMPTIONS

TASK 3. PRELIMINARY DESIGN
The purpose of the preliminary design is to identify, develop, and recommend the design
concept that successfully addresses the design problem, and to obtain the City's endorsement
of the potential improvements. The preliminary design will include drainage calculations and/or
modeling, identification of mitigation needs and potential locations, and preparation of the
preliminary design (60%) drawings. Per Halff's discussion with City staff, the drainage
calculations will be performed using 1 D/2D modeling. Specific tasks include the following:
1) Drainage Calculations
a) Existing Conditions Modeling — Develop an existing conditions model using
InfoWorks ICM (v6.0 or later) to evaluate the existing drainage patterns including the
roadside ditch network and overland flow. The modeling will utilize a 1 D/2D network
to determine the system baseline. A portion of the Corrigan ditch will be included in
the model since it is the receiving stream. Discharge hydrographs will be determined
using accepted methodologies; however, direct rainfall application may be used to
provide overland flow guidance. The 33% chance (3 -year) and 1% chance (100 -
year) storms will be evaluated.
b) Proposed Conditions Modeling — Update the models to include proposed conditions
storm sewer improvements and roadway improvements. Proposed pipes will be
added into the existing conditions network. The existing terrain will be modified to
incorporate changes to the streets and ditches. Model results will be compared to
the existing conditions to determine the peak discharge and volume increases.
c) Mitigation Measures — Identification of the mitigation required to offset impact
resulting from the proposed improvements. Potential locations will be evaluated and
a comparison to the existing and proposed modeling will be conducted to
demonstrate the effectiveness of these measures.
d) Inlet/Lateral Sizing — Calculations will be provided to adequately size inlets and
lateral lines. Standard inlet sizes will be used in the models to ensure consistency
with City design guidelines.
e) Overland (Street) Flow — Flow and elevations in the street will be evaluated using the
2D model to ensure that no negative impacts result from the proposed
improvements. Given the surrounding area and the fact that there is an existing
drainage problem, containment of the 100 -year within the ROW may not be possible.
Halff will work to achieve 100 -year flows in the ROW where possible.
f) Documentation — A memorandum will be prepared detailing the drainage calculation
process, methodologies, findings and recommendations. Applicable, figures, tables
and other information will be provided. Information including the overall drainage
area, drainage subbasins, loss parameters, times of concentration, pipe and street
conveyance, water surface elevations, and volume information will be provided.
Hydraulic Grade Line information from the model will be included on the plan &
profile drawings to ensure design criteria are satisfied.
2) Preliminary Design Drawings
a) Prepare preliminary (60%) plan set, including drainage calculation information,
overall alignments, plan and profile drawings of the proposed storm sewer and
paving improvements, outfall design, preliminary mitigation pond grading, etc. A
complete set of drawings will be provided as part of the preliminary (60%) submittal.

Re: Proposal for Geotechnical Services
City of Pearland Wagon Trail Road
Drainage and Paving Improvements
Pearland, Texas
Dear Mr. Barr:
In accordance with your request, Geotest Engineering, Inc. is pleased to submit this
proposal for the referenced project. The project is comprised of pavement and drainage
improvements approximately 1,600 LF along Wagon Trail Road between Broadway (FM 518)
and Bardet Road; approximately 650 LF along Cantu Road from Wagon Trail Road to the end;
and approximately 950 LF from Wagon Trail Road to the end. The improvements include
replacing the existing asphalt street with roadside ditches to a curb and gutter street with storm
sewers. The invert depth of the proposed storm sewer will be approximately 8 feet deep below
the existing grade. The proposed pavement will be asphalt pavement with concrete option.
Purpose and Scope
The purposes of this study are to evaluate the soil and water level conditions along
Wagon Trail Road, Cantu Road and Ochoa Road to provide geotechnical recommendations for
the proposed pavement and drainage improvements. Based on the information provided to us in
your e-mail dated August 1, 2016, the scope of this study will consist of the following:
• Provide utilities clearance for boring locations. This includes:
• calling Texas One Call referencing with street name and Key Map block
number.
• Coordinate with representative of utility companies to clear the marked
boring locations.
Mr. Terry M. Barr, P.E. Proposal No. 1140389599
Page 2 August 3, 2016
• Drilling and sampling a total of seven (7) borings to a depth of 15 feet for a total
drilling footage of 105 feet. The boring spacing is a minimum of 500 feet. Convert
one (1) boring into a piezometer at selected borehole location for steady state long
term water level measurements. The boring/piezometers programs is shown on
Attachment No. 1.
• Grout all boreholes except piezometer using non -shrink cement bentonite grout after
completion of drilling and water level measurements. The use of cement bentonite
grout will eliminate the potential problems and safety hazards associated with surface
settlements that might occur if boreholes are backfilled with soil cuttings.
• Perform appropriate laboratory tests on selected representative samples to develop
the engineering properties of the soil.
• Perform engineering analyses in accordance with the City of Pearland Design
Standards to develop geotechnical recommendations for bedding and backfill of
storm sewer, water level control for open cut construction and flexible and rigid
pavement thickness.
• Prepare a geotechnical engineering report.
Project Schedule
We should be able to start the fieldwork within two weeks after receiving your written
authorization. It is estimated that the fieldwork will be completed in about one (1) week barring
bad weather. The laboratory tests will be completed in about two (2) weeks. The final report,
which will include field and laboratory data and geotechnical recommendations, will be
submitted in about eight (8) weeks after receiving your notice to proceed.
Cost
Based on the scope of work outlined above, the cost of the field investigation, laboratory
testing, engineering analyses and geotechnical report is a lump sum amount of $10,763.00. A
cost breakdown is provided in Attachment No. 2.

NEN HALFF
Subsurface Utility Engineering
SCOPE OF SERVICES
Client: City of Pearland City / County Name: Pearland / Brazoria
Project: Wagon Trail Rd Drainage
Halff will perform Subsurface Utility Engineering (SUE) in accordance with ASCE CI/ASCE 38-
02 "Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data."
This standard defines the following Quality Levels:
Quality Level -A: Precise horizontal and vertical location of utilities obtained by the
actual exposure (or verification of previously exposed and surveyed utilities) and
subsequent measurement of subsurface utilities, usually at a specific point. Minimally
intrusive excavation equipment is typically used to minimize the potential for utility
damage. A precise horizontal and vertical location, as well as other utility attributes. is
shown on plan documents.
Quality Level -B: Information obtained through the application of appropriate surface
geophysical methods to determine the existence and approximate horizontal position of
subsurface utilities. Quality Level -B data should be reproducible by surface geophysics
at any point of their depiction. This information is surveyed to applicable tolerances
defined by the project and reduced onto plan documents.
Quality Level -C: Information obtained by surveying and plotting visible above -ground
utility features and by using professional judgment in correlating this information to
Quality Level -D information.
Quality Level -D: Information derived from existing records or oral recollections.
Quality Level -A: Utility Test Holes / Utility Location (Vacuum Excavation) —
Halff will perform up to ten (10) Quality Level -A Utility Test Holes for this project. Halff will
excavate an 8" x 8" test hole, record the depth of utility, backfill & compact test hole, and restore
the surface to its original condition. An iron rod with cap, nail with ribbon or "x -cut" will be set to
mark the location of the test hole.
Halff will make a good faith effort to locate all utilities, but shall be compensated for work
performed even if the utility is not located.
Quality Level -B: Utility Designation—
Halff will designate the approximate horizontal position of toneable utilities within the project
limits using geophysical prospecting equipment and mark using paint and/or pin flags. We
anticipate the designation of approximately 13,000 linear feet of utilities including buried
communication, electric, gas, water and waste water / sanitary sewer. Designation of irrigation
lines, storm drain and adjacent utilities within the corridor is not included in this proposal.
Because of limited utility record information, Halff cannot guarantee that all utilities will be found
and marked within the project limits.

;pp HALFF
Subsurface Utility Engineering
Quality Level -C: Utility Survey & Mapping —
Utility paint markings. pin flags, and all above ground utility appurtenances will be surveyed and
tied to supplied project survey control. Survey data will be processed and drawings depicting the
findings of the SUE investigation will be supplied to client in either MicroStation or AutoCAD.
Quality Level -D: Utility Records Research —
Available utility records will be provided to Halff by the City of Pearland. Halff will perform utility
record research as needed to successfully complete the project. Situations where the utility
does not have a metallic composition; a metallic tracer line attached: limited access to insert a
tracer line within it, the approximate location of the utility may be determined through the use of
available utility records and direct correspondence with the utility service provider if available. In
these areas, the utilities will be depicted as to utility records Quality Level -D.
Prosect Limits -
The project limits for this project are as follows:
Wagon Trail Rd: The apparent Right -of -Way of Wagon Trail Rd from south Right -of -Way line of
SH -518 south to the intersection of Bardet St.
Cantu Rd: The apparent Right -of -Way of Cantu Rd from the intersection of Wagon Trail Rd east
to the end of public roadway / property line of trailer park.
Ochoa Rd- The apparent Right -of -Way of Ochoa Rd from the intersection of Wagon Trail Rd
east for 900 feet.
SUE Field Manager / Professional Engineer
A SUE Field Manager will be on-site for a portion of this project for field crew supervision, field
quality control, and coordination with on-site personnel. A Professional Engineer will be
responsible for QA/QC, management of the contract, signing the final deliverables and
coordination with the project team.
SUE Deliverables / CADD
Deliverables for the designating work will include an electronic file (MicroStation and/or
AutoCAD format) containing the horizontal locations of the utilities. The utilities will be
referenced into the base / seed file provided.
A Test Hole Data Form will be completed and submitted to the City for each hole performed
indicating depth, size, and material of utility. Electronic files will also be provided in MicroStation
and/or AutoCAD format along with PDFs.

Memo
To: Clay Pearson, City Manager
From: Trent Epperson, Assistant City Manager
CC: Joel Hardy, Grants Coordinator
Richard Mancilla, Interim Ci ngineer
Date: August 25, 2016
Re: Drainage Issues on Cantu Road
Exhibit C
8/25/2016
To: Mayor and City
Council members
Further update on drainage
specific properties and general
area around Cantu Road. Clay
At the City Council meeting on August 22, 2016, a citizen spoke regarding repetitive
flooding losses on Cantu Road. The purpose of this memo is to provide an update on
staff activities to date and planned efforts to address the drainage issues in this area.
As part of the forthcoming Master Drainage Plan, the Corrigan Ditch Sub -Basin of Mary's
Creek was studied in an effort to alleviate repetitive flooding issues along the Wagon
Trail Road area, which includes Cantu Road. Initial efforts focused on re-establishing
and adding capacity to the storm sewer system along Wagon Trail Road south of Bardet
Street. Those improvement were completed by City staff several months ago and have
proved to be effective. Unfortunately, the solutions north of Bardet Street are much
more complicated and will require an engineered design. (See attached memo from
May 11, 2016)
Based on the study, a project was added to the FY2017 CIP to address the issues. Staff
is preparing to present an engineering design contract for approval by Council on
September 12, 2016, to design drainage improvements for the drainage sub -basin. This
design will take 9 months to complete, which will be followed by bidding and an
estimated 12 month construction project.
There are a couple of properties with structure elevations much lower than the already
low-lying surrounding area that the drainage project will not be able to address without a
much more significant cost. Staff has pursued grant programs to potentially move
forward with a buy-out on these properties but because they do not lie within the
mapped flood plain they do not have a high enough benefit cost ratio to qualify.
Therefore, staff is evaluating a City funded buy-out. This comes with many advantages
over a federal buy-out, including the ability to fill the property and re -sell the property,
putting it back on the tax rolls. Federal buy-outs require that the local entity perpetually
keep the buy-out property vacant and adds to our mowing responsibilities.
RESPONSIVE RESULTS -ORIENTED TRUST -BUILDERS ACCOUNTABLE
Throughout this process our City Engineer, Deputy City Engineer, Assistant City
Engineer, and Grants Coordinator communicated with the residents on a regular basis
(no Tess than bi-weekly), and have kept them updated and informed of various activities
over the course of this effort.
