EXECUTIVE SUMMARY
Recommendation to approve a change order to a work order in the amount of $55,260.00
to Post, Buckley, Schuh & Jernigan, Inc. (PBS&J) for contract #06-3969 "Fixed Term
Professional Engineering Services" for the Lely Area Stormwater Improvement Project
(LASIP), Whitaker Road Improvements (Project No. 51101) to include design and permit
modifications to reduce the construction cost ofthe project by more than $600,000.00.
OBJECTIVE: To add services to the existing contract by change order to assist the
Transportation Services Division, Stormwater Management Section in the design and permitting
of the LASIP Whitaker Road Improvements project. The need for these additional services is
described in greater detail on the attached Professional Engineering Services for LASIP
Whitaker Road Project - Scope of Work.
CONSIDERATION: The purpose of the overall LASIP project is to provide a comprehensive
stormwater outfall system for the area of East Naples, which has experienced an increasing level
of drainage related problems as growth has continued in the area. The drainage area of LASIP
consists of about 11,135 acres and consists of two sub-basins known as the Lely Canal Basin
system and the Lely Manor Basin system. The Lely Canal Basin discharges into an estuarine
coastal zone along the intercoastal waterway near Dollar Bay. The Lely Manor Canal discharges
into an estuarine coastal zone near the headwaters of Sandhill Bay and eventually into Rookery
Bay.
The Whitaker Road segment is one of twenty-seven components to the regional stormwater
project. This project is a continuation of the design and construction completed in FY09 for the
North Portion of the Lely Main Canal. The Whitaker Road improvements will drain into the
Lely Main Canal which will alleviate drainage problems within this portion of East Naples. The
land use within the basin consists of modem developments with improved water management
systems consistent with current design requirements, and older neighborhoods that were
developed before water management systems were required.
This segment of the project will provide stormwater design services utilizing the original
conceptual plans which include the LASIP improvements for all of Whitaker Road from County
Barn Road to the Santa Barbara corridor, including two 4' by 8' box culverts that will be
modified to reinforced concrete pipe. The first box culvert runs north and south under Whitaker
Road and is approximately 65 LF. The second box culvert runs north and south approximately
1,800 LF along the western border of Royal Wood Country Club. The proposed 4' by 8' box
culverts will be downsized to a culvert that is more appropriately sized. The scope of work
includes redesign of the conceptual 4' by 8' box culverts, permit modifications and address
utility conflicts. Reducing 1,865 LF of 4' by 8' box culverts to reinforced concrete pipe will
result in a construction cost savings by more than $600,000.
It is important to have this element of LASIP approved to continue the progress that the
Stormwater Management Section has achieved over the past three years. Many portions
including the larger, downstream outfall canals have been successfully constructed. The
Environmental Resource Permit to construct LASIP, which was issued jointly by the US Anny
Agenda Item No. 1681
February 9, 2010
Page 2 of 11
Corps of Engineers and the South Florida Water Management District, will expire on July 25,
2015. If the entire LASIP project is not completed by that date, modified permit requirements,
if allowed, could require additional costs, mitigation, and delays.
LEGAL CONSIDERATIONS: This item has been reviewed and approved by the County
Attorney's Office and is legally sufficient for Board action.-SRT
FISCAL IMPACT: Funding in the amount of $55,260.00 is available in the Stormwater
Capital Projects Fund (325) LASIP Project (Project No. 51101). The cumulative percentage of
the change orders is 50.12%. The cumulative dollar value of changes to this work order is
$99,210.00.
GROWTH MANAGEMENT IMPACT: The LASIP Whitaker Road Stormwater
Improvement project is in accordance with the goals and objectives of the Drainage Sub-element
ofthe Growth Management Plan for Collier County Stormwater Management.
RECOMMENDATION: That the Board of County Commissioners approve a change order to a
work order for the LASIP Whitaker Road project in the amount of $55,260.00 with PBS&J, Inc.
necessary for design and permitting changes.

Contract 06-3969
Scope of Work
Additional Professional Services Assignment
For
Roval Wood/Whitaker Road Culvert Modifications
BACKGROUND AND PURPOSE
As a result of additional analysis performed by PBS&J and confirrned by ABB (original
concept design consultant), we have determined that it is both feasible and cost effective
to reduce the size of the proposed box culverts utilized in the LASIP Phase II & 12
project. The storm water flows that are anticipated by ABB based on their master model
are significantly less than what the proposed 4 foot by 8 foot box culvert is capable of
conveying. Therefore, PBS&J recommends downsizing the box culvert to a culvert that
is more appropriately sized. This modification is estimated to reduce the construction
cost of the project by more than $600,000.
The purpose of this additional service agreement is to redesign the conceptually proposed
culvert and complete modifications to the SFWMD Environmental Resource Permit
(ERP) associated with this change.
The following scope of work is presented in accordance with Collier County Contract
Number 06-3969 "Fixed Term Professional Engineering Services".
SCOPE OF WORK
PBS&J will provide the following professional services:
Task .J - Desie:n Modifications
PBS&J will redesign the drainage system with appropriately sized reinforced concrete
pipe (RCP) in place of the conceptually proposed 4' x 8' box culvert. We will complete
modifications to the existing drainage report including revised calculations for the
conveyance culverts. PBS&J will coordinate with ABB concerning updates to the Master
Storm water Model. Modifications will be incorporated into the current site, grading and
drainage plans being developed by PBS&J. All details and cross sections will be updated
to reflect the updated design. Structural calculations and details will be revised to match
the new design. We will then coordinate and revise utility conflicts with modified storrn
piping. Finally, any conflicts with environmental impact calculations will be updated.
There are two 4' x 8' box culverts that will be modified to RCP. The first runs north and
south under Whitaker Road and is approximately 65LF. Design revisions for this culvert
will include resizing the culvert, redesigning headwalls at both ends, and modifications to
the gate structure. The second box culvert runs north and south approximately 1,800LF
along the property line of the Royal Wood Golf and Country Club. Design revisions will
include resizing the culvert, modifying the previously proposed headwalls to mitered end

Scope of Work
sections (MES), and revising manhole access points. PBS&J coordination with the
Royal Wood Golf Community will be on-going during the redesign of the culvert.
Task K - Permit Modifications
PBS&J will prepare the ERP modification application for submittal to the South Florida
Water Management District. The applications will consist of new ERP permit forms with
supporting documentation. PBS&J will meet with the SFWMD prior to submittal to
coordinate any issues with WMD staff. If necessary, we will respond to the District's
requests for additional information (RAIs). Finally, based on the agency comments
received during permitting the consultant will update the 100% Construction drawings in
preparation for bidding.
In total, it is assumed that an additional 2 meetings will be held with either the client
and/or permitting agencies.
SCHEDULE
PBS&J proposes to complete the above listed tasks within 120 days of receiving a Notice
to Proceed from the County. Obtaining permits from regulatory agencies is always a
difficult process to anticipate; however, PBS&J will show good faith and responsiveness
to any RAIs to expedite the permitting process. In the event a delay has been identified,
PBS&J will notify the County immediately.
BUDGET
In accordance with Collier County Contract Number 06-3969 compensation for the above
scope of work will be based on a billing type listed below.
PBS&J reserves the right to re-allocate funds within this project providing that the
total lump sum amount is not exceeded.
