Agenda 04/23/2024 Item #16B 9 (Two Agreements two pond sites required for Wilson Boulevard)04/23/2024
EXECUTIVE SUMMARY
Recommendation to approve two Agreements for the purchase of a pond site (Parcels 241POND and
242POND) required for the Wilson Boulevard (Golden Gate Boulevard to Immokalee Road) Project.
(Project 60229) Estimated Fiscal Impact: $555,500.
OBJECTIVE: To acquire a pond site needed for the Wilson Boulevard (Golden Gate Boulevard to Immokalee
Road) Project (the “Project”), which will expand Wilson Boulevard to four lanes; provide sidewalks; a shared use
pathway; bike lanes; drainage; and related improvements.
CONSIDERATIONS: Collier County is seeking to purchase Parcels 241POND and 242POND which, when
combined, will form a pond site needed for the Project. The attached Technical Memorandum, dated March 12,
2024, prepared by Bill Gramer, P.E. of Jacobs Engineering Group, confirms the suitability and need for these
parcels as a future pond site. Both properties are unimproved. Parcel 241POND is 2.81 acres in extent and owned
by Ghassan M. Saade, as Trustee of The Ghassan M. Saade Revocable Living Trust; adjacent Parcel 242POND is
2.34 acres in extent and owned by Tania G. Saade and Michelle G. Saade. Both parcels are located on the east side
of Wilson Boulevard approximately 1,300 feet north of Golden Gate Boulevard West, are rectangular in shape, and
total 5.15 acres.
The attached appraisal reports prepared by Collier County Review Appraiser, Lisa Barfield, dated March 18, 2024,
estimate the full compensation amounts for Parcels 241POND and 242POND to be $247,000 and $205,700
respectively, for a total appraised value of $452,700. The attached agreements reflect negotiated purchase prices
totaling $555,000 ($277,500 per property), including all attorney and expert fees and costs. The owners’ original
demand was a total of $700,000 for the two properties after initially declining to sell. By way of comparison, on
February 27, 2024, the Board approved the advanced acquisition/purchase of a 5.16-acre pond site on the west side
of Wilson Boulevard for $598,000 (Agenda Item 16B8). While properties on the west side of Wilson Boulevard
generally appraise higher than those on the east side (due to dual road frontage on 1 st Street NW, a relatively quiet
road), the value of the pond sites to the County is the same.
If these parcels are not acquired by negotiation, they will have to be condemned. Should condemnation become
necessary, the County will be required to pay attorney fees and expert witness fees according to sections 73.091 and
73.092, Florida Statutes, plus other expenses related to condemnation. Moreover, the availability of undeveloped
five-acre properties on the Project corridor is limited and their availability will decrease with future development.
If the County is required in the future to select less desirable pond sites due to lack of availability of preferred sites,
design, construction and maintenance costs will increase. Worst case scenario, the County could be required to
condemn improved properties and demolish homes to make way for future ponds. Staff accordingly recommends
that the Board of County Commissioners approve the Agreement, as a better result is not expected if parcels
241POND and 242POND are condemned.
This item is consistent with the Collier County strategic plan objective to design and maintain an effective
transportation system to reduce traffic congestion and improve the mobility of our residents and visitors.
FISCAL IMPACT: Funds of $555,500 are required, being the negotiated compensation amount of $555,000 and
estimated closing and recording fees of $500. The primary funding source for the acquisition of right of way is
impact fees. Should impact fees not be sufficient within a particular project, the secondary funding source will be
gas taxes. No maintenance costs are anticipated until such time as the Project is constructed.
GROWTH MANAGEMENT IMPACT: The recommendation is consistent with the Long-Range Transportation
Plan and Objective 1 of the Transportation Element of the Collier County Growth Management Plan to maintain the
major roadway system at an acceptable Level of Service.
LEGAL CONSIDERATIONS: This item has been approved as to form and legality and requires a majority vote

PRESENT ZONING: E-Estates FUTURE LAND USE: Estates-Residential
HIGHEST AND BEST USE: Based upon an analysis of the subject property and its environs (with consideration given to zoning, physical aspects of
the subject property, economic/market trends) the maximally productive use of the subject property would be for Estates-type single-family
development.
THE SALES COMPARISON APPROACH TO VALUE: Recent sales of properties generally similar to the subject are identified and compared to the
subject. Using the elements of comparison, the comparable properties’ sales prices are adjusted to produce value indications. The reconciliation of
these value indications is used to provide an estimate of a single value indication or a range of values.
DISCUSSION OF COMPARABLE SALES AND EXPLANATION OF ADJUSTMENTS: The following sales involve single-family homes located in
the Golden Gate Estates area. These sales are used to estimate the value of the subject property using the Sales Comparison Approach:
1. Golden Gate Blvd E, Naples Sale Price: $395,000 Sale Date: 11/2023
2. 1st St NW, Naples Sale Price: $300,000 Sale Date: 12/2023
3. 8th St NE, Naples Sale Price: $530,000 Sale Date: 08/2023
DISCUSSION OF COMPARABLE SALES AND EXPLANATION OF ADJUSTMENTS
Sale #1 is a 5 acre Estates zoned parcel located on the east of Wilson Blvd N on Golden Gate Blvd in the Golden Gate Estates area of greater
Naples. It is an unimproved wooded site. Normal topographical conditions for the area. The sales price reflects an underlying land value of
$79,000/acre. The lot has similar frontage on a busy four-lane road.
Sale #2 is a 2.5 acre Estates zoned parcel located on the west side of Wilson Blvd in the Golden Gate Estates area of greater Naples. It is an
unimproved wooded site. Normal topographical conditions for the area. The sale price reflects an underlying land value of $120,000/acre. The site
has superior frontage on a rural road.
Sale #3 is a 5.15 acre Estates zoned parcel located on the west side of 8th St NE in the Golden Gate Estates area of greater Naples. It is an
unimproved wooded site. Normal topographical conditions for the area. The sale price reflects an underlying land value of $102,900/acre. The lot
has similar frontage only on a busy two-lane road.
The sales cited show an underlying land value range of $79,000 to $120,900. In the current market, five-acre sites command a slightly higher
premium due to their appeal to developers seeking cost savings by developing two properties at the same time or buyers interested in acquiring
larger estates. This premium is applied to the subject property since the subject is being sold together with the contingent parcel. Even though sale
#2 is nearest the subject, it has significantly superior road frontage on a rural road. Sale number one is weighted most because it is the most recent
sale of 5-acre property on a busy road. The subject property would therefore be valued at: $87,900/acre x 2.81 acres = $247,000.

Order No.:
4500225624
Client: Collier County
Prepared by: Jacobs
Introduction
This technical memorandum has been prepared to provide the background and supplemental
information necessary for the County purchase of parcel numbers 37280400008 and
37280360009 for the purpose of constructing and maintaining a stormwater treatment pond
for the Wilson Boulevard Widening Project in Basin 1.
Background
Collier County initiated the Wilson Boulevard Corridor Study (2022) to evaluate future corridor
improvements to widen Wilson Boulevard North (Wilson Boulevard), from Golden Gate
Boulevard (CR 876) to Immokalee Road (CR 846) from a two-lane undivided facility to a four-
lane divided roadway with curb and gutter with a “closed” (Stormwater Inlets, Pipes, Ponds)
drainage system.
As part of the Study, a preliminary Pond Siting Report was created which evaluated the
stormwater recommendations and options for Collier County on the type, design, and location
of the stormwater management facilities for the proposed improvements. The preliminary
Pond Siting Report identified a minimum of 6 drainage basins required for the project, with a
combination of wet and dry ponds needed.
On August 21, 2023, Collier County entered into a service agreement with Jacobs Engineering
Group (Jacobs) for the Design Services for Wilson Blvd Widening (Contract No. 22-8006, Project
No. 60229). As part of the Design, a Final Pond Siting Report will be completed after the 30%
Design Submittal (Scheduled May 2024). However due to the potential for development along
the project corridor, potential pond sites (predominantly vacant parcels) may become
unavailable during the preparation of the Final Pond Siting Report and the Right-of-Way
Acquisition phase of the project. To expedite obtaining the required Pond Sites for the Project,
Jacobs has begun evaluating and identifying potential pond sites on a Basin-by-Basin basis (see
Attachment 1) that meet the project design criteria.

Design Criteria
The existing Wilson Boulevard corridor drains to the Cypress and Corkscrew Canals within the
North Golden Gate Basin (Water Basin Identification (WBID) 3278S), which is in the Big Cypress
area of Collier County and within the jurisdiction of the South Florida Water Management
District (SFWMD). The preliminary design of stormwater management systems for this project
is regulated by the rules and criteria set forth by SFWMD and the Florida Department of
Environmental Protection (FDEP). This section outlines the requirements to meet water quality
and quantity standards.
North Golden Gate Sub-Basin (WBID 3278S) is impaired for dissolved oxygen, with total
nitrogen as the causative pollutant. Although there is not a current Total Maximum Daily Load
or Basin Management Action Plan established, additional protective measures must be
incorporated into the project improvements to provide reasonable assurance that the
proposed discharge will not cause or contribute to violations of state water quality standards.
Retention, detention, or a combination of both in the overall system have the following
volumetric requirements:
Wet detention volume provided for the greater of the first 1 inch of runoff over the
drainage area or 2.5 inches of runoff over the impervious area (excluding water bodies)
Dry detention volume provided equal to 75 percent of referenced amounts for wet
detention
Retention volume provided equal to 50 percent of the referenced amounts for wet

Additional protective measures required by SFWMD include a site-specific pollutant loading
analysis and an additional 50 percent water quality treatment volume.
Basin 1 Pond Site Requirements
Basin 1 limits: From Golden Gate Blvd to approximately 0.55 miles north of Golden Gate Blvd
along Wilson Blvd.
The proposed pond sites for Basin 1 would outfall directly to the Cypress Canal. Two potential
pond sites were identified for Basin 1 to avoid impacts to numerous water supply wells and
minimize distance to the canal. Piped conveyance systems to the potential Basin 1 pond sites
would be located within the Wilson Boulevard ROW. The Pond 1 outfall pipes to the Cypress
Canal may be located within the Wilson Boulevard ROW.
Based on the above Design Criteria and the amount of needed treatment and attenuation for
the proposed amount of impervious area, the need for an approximate 4 Acre Pond Site has
been identified for Basin 1.

Recommendation
Jacobs identified 2 viable options for Basin 1 (see Attachment 1):
• Pond Site 1-1: Consisting of Parcel Numbers 246RDUE and 247RDUE (Total 4.52 Acres)
• Pond Site 1-3: Consisting of Parcel Numbers 241RDUE and 242RDUE (Total 4.51 Acres)
Pond Site 1-3 was selected as the preferred alternative due to less anticipated wetland impacts.
Additionally, the two tracts comprising Pond Site 1-3 are controlled entirely by one person who
owns one of the tracts and controls the trust that owns the second tract, whereas Pond Site 1-1
consists of two owners.
The parcels identified for Pond Site 1-3 are required for a stormwater pond in Basin 1, and at
this time Jacobs is requesting the County acquire these parcels to accommodate the
stormwater treatment and attenuation needed for the Wilson Boulevard Widening Project.
