Action
Requested: Approve an Engineering Services Agreement (ESA) with Halff
Associates, Inc. to provide survey and engineering services for
storm drain and sidewalk improvements near the intersection of
North Peytonville Avenue and Raven Bend Court in amount not to
exceed $59,500.
Background
Information: Currently the southern detention facility from the Shady Oaks,
Phase 3 subdivision has a non-traditional outlet which releases into
the North Peytonville right of way, causing storm runoff to surface
flow across the intersection of North Peytonville and Raven Bend
Court. In major rain events, this water can be several inches deep
which poses a safety concern for the traveling public. Ribbon curbs
and concrete flumes have been installed in years past to help direct
the low flows nicely, however they are quickly overwhelmed in
larger events.
This agreement includes topographic survey, a detention analysis
of above referenced facility, and construction plans for proposed
solution. The desire is to provide a traditional pond release
structure and underground storm line that will convey the storm
runoff to the bar ditch on the west side of the intersection. A
downstream assessment will be performed to confirm no increase
in discharge to the receiving ditch. Also included are construction
plans for approximately 125 feet of sidewalk to close a gap from the
southwest corner of Shady Oaks subdivision to Raven Bend Court.
Finally, Halff Associates will provide bidding and construction phase
services for this project.

within the project budget.
Strategic Link: This item links to the City’s Strategy Map strategic focus area of
Safety & Security, Mobility and Infrastructure. It specifically relates
to the City’s Corporate Objectives, C1: Achieve the Highest
Standards of Safety & Security and F2: Invest to Provide &
Maintain High Quality Public Assets. The Critical Business

Scope of Work
North Peytonville Storm Drain and Sidewalk Improvements
Southlake,Texas
GENERAL—Halff Associates will perform a detention analysis of the Shady Oaks Phase 3 detention
pond at the southwest corner of the development to determine the impacts of converting the existing
walled detention structure to a traditional pond structure. The pond discharge will be piped from a
proposed flow-controlled outlet structure and discharge to the existing ditch at the northwest corner of
North Peytonville Avenue and Raven Bend Ct. The improvements will include approximately 120 linear
feet of sidewalk along the east side of North Peytonville Avenue north of Raven Bend Ct and
approximately 180 linear feet of storm drain with alignment based on SUE services described below.
Halff will provide the following services:
I. Detention Analysis—Halff will perform a detention analysis utilizing the InfoWorks ICM
model developed as part of the Kirkwood/Higgins Branch Watershed Study to evaluate the
proposed detention structure and outfall piping described above. The detention analysis will
determine proposed peak discharge rates from the pond to be at or below existing peak
discharge rates compared to as-built design plans.A downstream assessment will be performed
to confirm no increase in discharge to the receiving ditch at the northwest corner of the
intersection of North Peytonville Avenue and Raven Bend Court. Erosion protection will be
evaluated at the piped outfall from the pond. The analysis will be documented in a brief letter
report with exhibits.
II. Topographic Survey—Halff will provide the survey services necessary to design the proposed
improvements. The survey will include:
a. Establishing control based on City of Southlake Survey Control Points. Set additional
horizontal and vertical survey control points suitable for use in design and construction.
b. Field tie visible existing facilities required for final design including existing paving,
curb,gutter,signs,building finished floor,building corners,pavement markings,trees,
shrubs, above ground utility appurtenances,property corners,and any other surface
features on and adjacent to the site.
c. Prepare a 0.5' contour interval topographic survey of the site and adjacent areas.
III. Subsurface Utility Engineering Services—Halff will perform SUE in accordance with
ASCE Cl/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.
j
Quality Level-D: Information derived from existing records or oral recollections.
Quality Level-A Utility Test Holes (Vacuum Excavation):
Up to two (2) test holes will be performed on various utilities at locations specified by City of
Southlake.Halff will cut up to a 12"square test hole,excavate down to utility,record the depth
to top of utility,backfill&compact the hole, and restore the surface to its original condition.
An iron rod with cap or"x-cut"will be set to mark the approximate centerline location of the
utility. A jackhammer will be utilized for work to be performed in asphalt and concrete areas.
Quality Level-B Utility DesignatinX.
Halff will designate the approximate horizontal position of conductive/toneable utilities
within the project limits using geophysical prospecting equipment and mark using paint
and/or pin flags. We anticipate the designation of utilities including buried communication,
natural gas, water, waste water/sanitary sewer, and storm drain/storm sewer. Designation of
irrigation lines,HDPE lines,gathering lines,asbestos concrete and/or pvc lines,as well as pvc
lines without tracer wire or access are not part of this Scope of Services.
Because of limited utility record information and the possibility of non-conductive/un-
toneable utilities, Halff cannot guarantee all utilities will be found and marked within the
project limits.
Quality Level-C Surveying
Quality Level-B Utility Designation paint markings, pin flags, and above ground utility
appurtenances as well the iron rod with cap or"x-cut" for Quality Level-A Test Holes will be
surveyed and tied utilizing project survey control provided by others.
(Quality Level-D Records Research:
Available Records will be provided to Halff by City of Southlake. Halff will perform additional
utility record research as needed to successfully complete the project.
Because there are situations where the utility does not have a metallic composition; a metallic
tracer line attached; access to insert a tracer line within it, the approximate location of the
utility may be determined through the use of utility records and direct correspondence with
the utility owner/representative. In these areas, the information will be considered Quality
Level-D, depicted according to utility record information only.
SUE Field Manager / Professional En ' eer:
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,coordination with the project team and
signing the final deliverables if required.
Ltjght-of Entry;
Right-of-Entry is not part of this Scope of Services as work is anticipated within the existing
road Right-of-Way. If Right-of-Entry is required, it will be performed and provided to Halff
by City of Southlake.Halff will coordinate with property owner(s) once right of entry has been
obtained.
Permitting:
Street Cut permits will be coordinated with the City of Southlake as required.
Work Zone Traffic Control:
Halff will provide standard temporary work zone traffic control consisting of cones and free-
standing signage for this project. Exact test holes locations are unknown and any required
certified traffic control to be provided by Dallas Lite&Barricade,if needed.
If an engineered traffic control plan is required for permit approval or if unique traffic control
conditions exist, Halff will notify City of Southlake and submit a supplemental agreement for
authorization prior to proceeding with additional work.
IV. Construction Plans—Halff will prepare the following construction plans and specifications
using typical engineering scales formatted to 22-inch by 34-inch sheets suitable for reduction to
11-inch by 17-inch sheet size. These plans will incorporate comments received during the
predevelopment meeting and client review.
a. Cover Sheet—The cover sheet will be prepared in accordance to City development
standards for permit submittal.
b. Layout Sheet and General Notes—This sheet will define the survey control and
provide specifications and notes to govern construction and meet City design criteria.
c. Demolition Plan—The demolition plan will show the construction limits and features
to be removed and protected. The sheet will include details as necessary.
d. Paving and Grading Plan—The paving and grading plan will define the proposed
paved and non-paved surfaces on the site and indicated the proposed grades. The plan
will indicate drainage paths,high points,and surface slopes necessary to illustrate Texas
Accessibility Standard compliance. Pavement marking and signage will be included in
the plan.
e. Drainage Plan and Calculations—Halff will document the drainage calculations in
accordance with the City of Southlake Drainage Design Criteria. The plan will include a
plan and profile of the proposed storm drain with design HGL shown.
£ Detention Pond Grading and Calculations—This sheet will provide detention
grading and outlet structure design/calculations.
