GENERAL SCOPE OF SERVICES
LEBOW CHANNEL SCHEMATIC PLAN
City Project No. 00084
Scope for Engineering Design Related Services for Storm Water Improvements Projects
The scope set forth herein defines the work to be performed by the ENGINEER in
completing the project. Both the CITY and ENGINEER have attempted to clearly define the
work to be performed and address the needs of the Project. Under this scope, "ENGINEER"
is expanded to include any sub-consultant, including surveyor, employed or contracted by
the ENGINEER.
OBJECTIVE
The objective of this contract amendment is to supplement previous scopes of work on the
Lebow Channel. This additional work includes: evaluating existing detention effects and
potential detention pond improvements in Upper Lebow, north of 36th Street, in order to
determine:
• What detention improvement alternatives will eliminate the need for channel
improvements downstream, between DeRidder Ave. and 36th St.?
• What detention improvements will allow for downstream channel improvements to be
contained within the existing 40' Drainage Right of Way (DeRidder Ave. to 36th St.)?
• What potential water quality enhancements could result from or be incorporated into
these proposed detention facilities?
• What is the cause of flooding along the north side of DeRidder Ave. between Blue
Mound Rd. and Lebow Channel, and what are potential mitigation measures?
• What are the anticipated FEMA mapping needs and/or Section 404 environmental
permitting needs associated with each improvement alternative?
WORK TO BE PERFORMED
TASK 7. DETENTION EVALUATION UPSTREAM OF 36TH ST.
ENGINEER will evaluate detention improvement alternatives for various locations upstream
of Terminal Rd. in combination with channel improvements between DeRidder Ave. and 36th
St. Improvement alternatives will be evaluated based on constructability, cost, and
downstream impacts, including water quality enhancement potential. Results and
recommendations will be summarized in report format.
Basic Services for Task 7 will be compensated on a lump sum basis and include:
7.1 Data Collection — Collect additional data pertaining to existing detention ponds, and
stormdrain infrastructure pertinent to evaluating existing conditions and improvement
alternatives. In addition to geospatial data previously obtained for this project,
anticipated data includes as-built drawings, information regarding potential
development projects, field observations, and flood complaint data from the CITY's
archives. Anticipated field data includes observing field conditions for potential

improvement opportunities, conflicts, and land availability. This will also include
measurements for calculating storage volumes, verification of outlet structures and
conditions, etc...to help determine/validate stage-storage and discharge rating
curves.
7.2 Existing Conditions Analysis—This Task item involves updating the Schematic Plan
model (HEC-HMS) to include existing detention facilities in sub-basin DA-1, which
includes all runoff upstream (west) of Blue Mound Rd. Modeling data for existing
facilities will be based on data collected as part of Task 7.1, which does not include
ground surveys. The model prepared for this Task will serve as the base condition
model for the remainder of this study. Results will be documented in a brief
summary report including: analysis methods, peak discharges, pond routing
summaries, and graphical representation of existing detention facilities.
7.3 Property Evaluation for Detention Improvements— Based on preliminary findings in
Tasks 7.1 and 7.2, ENGINEER will evaluate existing detention sites to determine the
practicality of modifying and/or enlarging these facilities to provide additional
detention capacity. ENGINEER will also evaluate existing storm drainage systems
and/or runoff patterns to determine the practicality of routing additional drainage
through existing or future detention facilities. The ENGINEER will coordinate with
CITY to identify and/or eliminate properties from the evaluation. Findings and
recommendations will be discussed with CITY at a coordination meeting and
documented in a combined summary report with Task 7.2. At the conclusion of Task
7.3 the ENGINEER, in conjunction with the CITY, will have determined every
property that is to be considered for the improvement alternatives of Task 7.4.
7.4 Improvement Alternatives— Develop and evaluate up to six (6) improvement
alternatives to address flood risk along Lebow Channel, north of 36th St. Each
alternative will consist of detention ponds, channelization, or some combination of
both for all properties/facilities identified in Task 7.3. Supporting hydrologic and
hydraulic models will be performed using HEC-HMS and HEC-RAS. Anticipated
alternatives include:
1. 100-YR Design Storm within existing channel,
2. Design Storm Variance within existing channel,
3. 100-YR Design Storm, maximize existing easement,
4. Design Storm Variance, maximize existing easement
5.
Following the completion of Task 7.3 the ENGINEER will prepare a more detailed
description of each alternative, and schedule a coordination meeting with City staff to
refine the list of hydrologic and hydraulic model alternatives to be evaluated. Any
alternative evaluated beyond the four (4) selected, will be considered outside the
scope of this Task.
To complete the study; the methods, results, recommendations, and opinion of
probable construction costs will be documented in a summary report, including:
tables, schematic level graphics, and digital support data.

TASK 8. STUDY THE CAUSE OF FLOODING ALONG DeRIDDER AVENUE
ENGINEER will study the cause of flooding for the repetitive-loss properties along DeRidder
Ave., and evaluate potential mitigation measures.
Basic Services for Task 8 will be compensated on a lump sum basis and include:
8.1 Survey—Collect ground survey data to better define the berm and drainage paths
along DeRidder Ave. on the north side, between Blue Mound Rd. and Lebow
Channel. This task does not include a full topographic survey.
8.2 Evaluate Flood Source— Perform a more detailed analysis of the existing pond,
outfall structure and berming/grading around the pond to the north of these
properties (on the former FAA site). The survey and detention analysis are
anticipated to either reveal or eliminate the pond as the source of flooding along
DeRidder. If the pond is ruled out as the flood source, lot-to-lot drainage and street
drainage will be evaluated as possible sources.
8.3 Improvement Alternatives— Based on the findings of Task 8.2, develop improvement
alternatives that can address the flooding issues, and that can be implemented
independently of the overall Lebow Channel improvements. Findings and
recommendations will be summarized in a letter report, including opinions of
probable construction cost.
ASSUMPTIONS
• Up to two (2) meetings with CITY to facilitate the study and present the summary
report.
• Improvement alternatives for this task will be evaluated based on the existing
conditions model generated in Task 7.2 along with additional detailed survey
data. These improvement alternatives will be independent of any channel
improvement alternatives listed in Task 7.

COUNCIL'ACTION: Approved„on,10/2/2012
DATE: Tuesday, October 02, 2012 REFERENCE NO.: **C-25896
LOG NAME: 20SW 00084 LEBOW AMEND. 4
SUBJECT:
Authorize Execution of Amendment No. 4 to City Secretary Contract No. 32301,an Engineering Agreement
with Teague Nall and Perkins, Inc., in the Amount of$24,505.00 for the Stormwater Utility Project-Lebow
Channel Watershed Improvements (COUNCIL DISTRICT 2)
RECOMMENDATION:
It is recommended that the City Council authorize the execution of Amendment No. 4 to City Secretary
Contract No. 32301 with Teague Nall and Perkins, Inc., in the amount of$24,505.00, thereby revising the
total contract cost to the amount of$1,009,552.00.
DISCUSSION:
The Amendment recommended by this Mayor and Council Communication is for engineering services for
the evaluation of additional detention options for the Lebow Channel Drainage Improvement project north
of 36th Street and primarily north of the current project boundaries.
The additional scope was identified during a project charrette attended by public officials, city staff from
multiple departments, the local neighborhood association, and other outside agencies and groups. The
project is needed because of residential flooding'and roadway overtopping.
The Lebow Channel program is a large, multi-phase program that will address residential, commercial,
and light-industrial property flooding and roadway overtopping/flooding. Over 280 homes/structures are
located within this section of the floodplain and are subject to property flooding. Additionally, 17 roadway
crossings are subject to overtopping. Due to the size and cost of the overall program (approximately$30
million), the program was developed to be designed and constructed in phases and will likely not be fully
completed until at least 2020. Teague Nall and Perkins, Inc. (TNP)was selected to design the project
based on a Request for Qualifications (RFQ)process. The City Council originally authorized the City
Manager to execute an engineering Agreement with TNP(M&C C-20925)in the amount of$243,000.00. It
was anticipated that the contract would be amended for additional project phases. Amendment No. 1
(executed administratively), Amendment No. 2 (M&C C-23031), and Amendment No. 3(M&C C-25219)to
TNP's contract, totaling $741,147.00, have subsequently been authorized for the phases of work
completed to this point.TNP proposes to perform the engineering services described for a lump sum fee
of$24,505.00. Staff considers the fee to be fair and reasonable for the scope of services proposed.
Previous engineering phases included: stormwater runoff analysis of the channel, surveying associated
with property acquisitions, and design work for the elimination of two low-water crossings. The scope of
work for the phase represented by this Amendment includes evaluation of additional detention options
north of 36th Street and primarily north of the current project boundaries.
Funding for this project is being provided from the 2004 Capital Improvement Program,the Stormwater
