Task1
1. There is an existing 8-foot high privacy wall along the south side of Vanderbilt Beach Road(VBR)going west from
Goodlette-Frank Road, approximately 2,800 feet in length,that needs replacement.This task will include the design to
remove and replace the existing wall with a new 8-foot high concrete privacy wall(post and panel system).The total budget
for Task I is$60,598.
2. The Collier County Road Maintenance Division maintains this wall and requested the replacement be included in this
project.A 300-foot section was damaged by Hurricane Irma in 2017 and was already planned to be replaced with this
project. However, Hurricane Ian in fall of 2022 contributed to the rapid deterioration of the remaining section, resulting in
the need to replace the entire wall.
3. If the change is not processed,the wall replacement will need to be completed as a separate project. Replacement of the
wall is less costly and more efficient if completed at the same time as the construction of the roadway widening project.
Task 2
1 The full median opening at the intersection of Bay Laurel Drive (Pelican Marsh) and VBR is being removed as part of the
roadway widening design.A channelized median(prohibiting left turns)is the preferred and safer design on a 6-lane roadway.
As a result, a westbound U-Turn is needed within a reasonable distance between Bay Laurel Drive and the signalized
intersection of VBR and Goodlette-Frank Road.Therefore,this change in design consists of adding a westbound U-Turn Lane
on VBR just east of the intersection with Goodlette Frank Road.The total budget for Task 2 is$18,330.
2 The original design anticipated that U-turns would be available at the intersection of VBR and Goodlette-Frank Road.
Recent design changes eliminated this option due to the geometric layout of the intersection and signalization requirements.
During public outreach Pelican Marsh requested that we provide them with a U-turn in advance of the intersection.
3 If this change is not approved, a signal-protected U-Turn at the intersection would have to be accommodated which would
negatively impact the traffic capacity at the intersection.

to vegetation, drainage and utilities.
1.3: Vertical Alignment Evaluation—Set Alignment(Best Fit Options) - Evaluate the existing
vertical alignment of the wall and prepare alternative for placement of new wall.Note: It is
assumed that the elevation of the new wall will approximate the elevation of the existing wall
with minor modifications to better conforms to existing terrain.

construction limits/zone and anticipated access to wall location along the north and south sides
of the wall. Access from the south side of the wall will require a Right-of-Entry from the
adjacent development. Coordination will the Development and Costs associated with ROE
Agreement(if applicable) will be the responsibility of the County.

VANDERBILT BEACH ROAD 6-LANE WIDENING (CR 862)
FROM US 41 TO AIRPORT-PULLING ROAD
Naples, Collier County, Florida 34108
Socotec Consulting Inc. Project Number 564-025.01
Socotec Consulting, Inc. (SOCOTEC) is presenting this Expansion of Scope proposal to address
the latest request regarding the sound wall in place along the western portion of the project. The
soundwall is present along the south side of the road beginning at Strada Place in the west and
extending to near Goodlette Frank Road for a distance of about 3,000 feet.
You have requested that we complete a series of hand augers along the wall at a spacing of about
250 feet. Soils will be collected, identified, and subjected to selected lab testing. Results of our
testing will be presented in our final report along with the other work we are currently completing.
