OLD BUSINESS

Update Regarding Martin County Litigation

The Attorney reported the following update on the litigation filed by Martin County and SFWMD as follows:
On August 12, 2020, the Circuit Court entered two Final Judgments in the litigation. The Final Judgments essentially concluded that as a matter of law, lands owned by both Martin County and SFWMD are immune from the levy of non-ad valorem special assessments and the Special Districts have no legal authority to levy such assessments on these lands.
On September 10, 2020, Hobe-St. Lucie Conservancy District, through its appellate counsel, filed a Notice of Appeal with the Fourth District Court of Appeal.
On January 4, 2021, Hobe-St. Lucie Conservancy District filed an Initial Brief and Request for Oral Argument. The Florida Association of Special Districts (“FASD”) subsequently filed an Amicus Curiae (Friend of the Court) Brief in support of the District on January 12, 2021.
On March 5, 2021, both Martin County and SFWMD filed Answer and Briefs and Requests for Oral Argument.
On April 16, 2021, Hobe-St. Lucie Conservancy District filed a Reply Brief.

On November 17, 2021, the District Court of Appeal issued its written decision in favor of the District and reversed the summary judgment previously rendered in favor of the County and SFWMD. The Court stated in part, that both the County and SFWMD improperly conflated the terms “assessment” and “tax” “to justify their position”, and held that the District had correctly imposed a special assessment and not a tax. It further held that Sections 298.305(1) and 298.54 “provide the requisite statutory authority for imposing the special assessment,” and that Section 298.36(1) has no effect on Section “298.305(1)’s mandate to assess all lands.” The Court concluded that the reading of the law by the County and SFWMD “violate the clear mandate of 298.305(1),”

noting that both entities had paid these assessments for over twenty years.

Martin County and SFWMD filed Motions for Certification of Conflict and Great Public Importance. The District timely filed a Response on January 18, 2022. The District has also filed a Motion to Tax Appellate Costs.
On January 20, 2022, the Court denied the Motions for Certification of Conflict and Great Public Importance filed by Martin County and SFWMD.
On February 1, 2022, Martin County and SFWMD filed Motions to Stay Issuance of the Mandate. On February 10, 2022, the District filed a Response opposing these Motions.
On February 15, 2022, the Court denied the Motions to Stay Issuance of the Mandate.

On February 18, 2022, Martin County and SFWMD filed Notices to Invoke the Discretionary Jurisdiction of the Florida Supreme Court.
On February 28, 2022, Martin County and SFWMD filed their jurisdictional briefs.

On March 4, 2022, the District Court of Appeal issued its Mandate, which remands the case to the Circuit Court for entry of summary judgment in favor of the District.
On March 24, 2022, the District filed its Brief on Jurisdiction opposing jurisdiction of the Florida Supreme Court against Martin County and also SFWMD.
A hearing was held on July 15, 2022 on the District’s Motion for Entry of Final Judgment.

The Final Judgment dated July 15, 2022 was entered.

The judge has also entered an Agreed Order Taxing Appellate Costs in favor of the District, which has been paid.
The Florida Supreme Court rendered its decision regarding jurisdiction on July 20, 2022. No motion for rehearing will be entertained. The effect of the Supreme Court Order is that the ruling of the 4th District Court of Appeal controls. See Hobe-St. Lucie Conservancy District v. Martin Co. (Fla. 4th Dist. Ct. Appeal November 17, 2021).

Update Regarding RG Reserve Pipe Permit Application

The District Engineer stated that RG Reserve met with South Florida Water Management District. The Reserve Mitigation Bank was not doing its job to maintain and enhance the wetlands and there had been adverse impacts to the District in the form of a berm washout. The Board had directed the District Engineer notify South Florida Water Management District of the damage issues and to coordinate with South Florida Water Management District regarding the failure of RG Reserve to comply with the RG Mitigation Bank Permits.
The District Engineer stated SFWMD asked RG Reserve to work with HSLCD, with the understanding RG Reserve needs to pay HSLCD for the damages. The District Engineer indicated the landowner to the north was being brought in. The District Engineer was directed to continue to follow up regarding the Mitigation Bank Connection.
Update Regarding Howe Holdings Agreement

The District Engineer commented on Howe Holdings.

The District Engineer explained that Howe Holdings had a lease back with Thomas Produce and Thomas Produce has paid the past charges for 2021.

J),	"Purpose and Scope

he purpose of this Water Control Plan is to modify the UnitofDevelopment No. IA HSLCD improvements/facilities cu1Tently operated and/or maintained by HSLCD. Existing Di.strict facilities will be modified, and new facilities constructed, as necessaiy, to facilitate further changes in development plans for the proposed Discove1y PUD subdivision and to acco1mnodate a new golf course and ancillary facilities.

This Water Control Plan provides for the proposed project that will be developed by Discovery Land Company and will consist of a maximum of 317 residentialunits on 1,530.89 acres, which

2

equates to a gross residential density of approximately 1 unil per 5 acres. The residential lots will be surrounded by approximately 200-acres of lakes, an 18,hole Golf Course, and more than
124.41 acres of native wetland and upland habitat that will be restored adjacent to the Atlantic Ridge Preserve State Park. The lake front amenities include aGolf and Clubhouse with ten golf suites and an Outdoor Family Recreation and Sports Park. 'Jh.e Golf Course will also feature two driving range facilities, a Par 3 mini ooUise, and Clubho11se with teaching and practice facility.

The existing Polo Club equestrian uses the polo fields alongtl1eBridge Road :frontage which will be maintained and enhanced by additional support faciliiies iitcluding expansion of the existing Equestrian/Polo club facilities, addition of equestrim-orientated neighborhood, and riding trails throughout the project. A Right of Way dedicated to HSLCD from Bridge Road to the Atlantic Ridge Preserve State Park along the east boundaryof fu_e project will be constrncted.

The proposed golf course and residential lots will be graded sig11ifi.cantly higher than existing grade. The proposed topography for these will have elevations in the range of 45 feet NAVD which will require approximately 30 feet of fill above existing grade.

The project proposes the use of a potable water distribution system and wastewater collection system. The utility provider will be South Mar6n Regional Ulilities by way of water main and
force main extension improvements. Tract wm be dedicated to HSLCD for future use. These
features are plaimed to enter the site from the North.

he land area within Unit of Development No. IA encompa$esappro:ximately 1,530.89 acres and is located in the uninco1porated area of Martin County, Florida. All of Unit of Development No. 1A lies within the original HSLCD Unit 1. A location map of Unit of Development No. lA in relation to the boundaries of HSLCD is shown in Exhibitl. The legal description and map for this Unit of Development is shown in Exhibits 2-1 and 2-2.

The proposed project is located within Unit of Development No. lA, north of Bridge Road, roughly one mile east of the I-95 Interchange in unincoxporated Martin County, Florida. The project includes all oftl1e Hobe Sound Polo Club recorded plal, which consists of approximately l ,307 acres, and Tract A and D of the Hobe Sound Equestrian club recorded plat, which consist of approximately 223 acres. The Hobe Sound Polo Club, consisting of 50 twenty acres lots, was paiiially constructed.

The property changed to "Rural Lifestyle Development'' land use but shall be converted from 50 twenty acre lots to the afore mentioned ranch sites and golf course and supporting facilities.

l!.	Lands outside HSLC]) Boundaries ReceivingServices

Lands that are outside the boundaries of Unit of Developmeo.t No. lA that connect with the water control system within the Unit of Development No. 1A sre illustrated in Exhibit 3. Lands outside HSLCD boundaries shall continue to receive drainage services, although some modifications to the existing system are required under this planas illustrated in Exhibits 4-1, 4-2 and 4-3.

Thomas Produce is a 300-acre agricultural site located to the sou1b.east of Unit of Development No, lA. These lands connect with the water control system witlun, and receive drainage service-s through, the Unit. Water drains through a 48" culvelt to the i111emallake system where 1 inch of water quality trea1ment will occur.

Atlantic Ridge Preserve State Park is a 4,886-acre preserve looated between U.S. 1 (Federal Highway) and the South Fork of the St. Lucie River, at the north.end of the Unit of Development No. lA. It passes water from the east side of the Unit, along lh.e canal on the north of the Unit, to the Outfall Canal OC-1 (see Exhibit 3) via a flow through we1land preserve, then flows continuing westward to Outfall Canal OC-1, which will be reconstructed.

At the south end of Unit of Development No. IA, the "South. Fork Canal" passes water from Lands South of Unit of Development No. IA to the internal lake system. The flows will be piped along the west boundary. These lands drained through 1he HSLCD prior to the construction of any water management system and continue to do so without an agreement or permit.

G.	''Nest Boundary Culvert Sizing

The 1,664-acre drainage area south of Bridge Road will be piped by culvert. This area generates a flow of 44.2 cubic feet per second. Using a 60-inch culvert 1·esults in a headloss of 0.57 feet. This culve1t is shown on Exhibits 4-1 and 4-2.

The analysis calculates the headloss for a 60'' HDPE culvert length of 2,355 feet using a 44.2 cubic feet per second (CFS) flow using Manning's equation:

4

Q = Av= (1.49/n)A(R 2'3)S1l2
Where:
Q = Flow Rate, (ft?Is) v = Velocity, (ft/s) A= Flow Area, (fi2)
n = Manning's Roughness Coefficient
R = Hydraulic Radius, (ft)
S = Slope or gradient, (ft/ft)

From this equation we estimated the "slope" or gradient between 1:h.e water elevation at the culve1t inlet and culvert outlet, and the length of the culvert. The aialysis uses a Manning's value for HDPE of0.012.

:U.	Existing Conditions in the Unit of Development No.lA Area

Topography
USGS Quad Sheet Gomez shows elevations ranging betwee11l 5 and 17 feet National Geodetic Ve1tical Datum 1929 (''NGVD 1929") for the area within the l.rnit of Development No. lA boundaries. Upit of Development No. IA generally slopes dovmward from south to the nortl1.

The existing onsite soils are predomi11.antly Wabasso Sand, Riviera Fina Sand, Pineda Sand, Floridiana Fina Sand (depressional), and Riviera Fine Sa.tid (depressional). The soils characteristics are nearly level, poorly drained sands with water tables strongly influenced by the conveyance features in and around the site. The site wasdeveloped for citrus crops many years ago but is presently a pa1tially completed Hobe Sound Polo Club.

The site consists of existing roads, swales, and canals tlmt provide site drainage and limit the elev!;ltion of the water table onsite. The elevation of the Seasoru.al High-Water Table (SHWT) is estimated to be between 7.0 and 8.0 feet NAVD based on data from previously permitted projects on this site and is heavily influenced by the perimeter canals. The average SHWT determined by recent project specific borings will be used fort hecoJ1trol elevation for thepost­ development condition which will be 8.5 ft. NAVD. The GrDve Golf Club, which is adjacent to this site, maintains a control elevation of 6.0 feet NAVD.

Land Use and Zoning

he historic land use within Unit of Development No. lA is p.rimarily agricultural land use. The previous land use is residential twenty-acre ranch sites, a proposed golf comse, and ancillary facilities.

Unit of Development No. lA is located in the unincorporated area ofMa1iin County, Florida. he Martin County Zoning classification for the Unit of Develo]Jment No. lA area is listed as
(Agricultural). TI1e proposed land use is to be aPUD.

Bistoxy of Water Control for the Area

The design criteria for the water control system is listed below. This information is based on the design crite1ia contained in the HSLCD Unit 1 Water Control Plan, dated April 2007.

A series of water control plan amendments for the existing Unit l development have been updated since 2007 (see next page).

Channel Design Criter·a-Drainage

Thedrainage capacity of the system is designed for 1he peak removal of 4 inches of sm-face water in 24 hours, at flood stages. The basic average design capacity is 2 inches removal in 24 hours, with charuiel stages maintaining a 2-foot freeboard. All charu.1els are designed with a 1:1 side slope. Grades and cross sections are designed for a maximum flow velocity of 2 feet per second.  Culverts are designed for a
velocity of2 to 4 feet per second, and of a size that1Vill create ahead ofno more than
0.2 feet within the length of the culve1t at full flow. ChaI111el sections and grades are designed to preserve a free water table in the adjacent soil of 48 inches below the ground surface if possible.

Channel Design Criteria -	Irrigation

The HSLCD drainage channel system is also available for use for the distribution of irrigati011 wate:ts. The capacity of the chaimel system is the n01mal movement of 2 inches of surface water in 24 hours. The inigation supply is generally designed for au application rate of not more than 1 inch in 24 hours. The channel systein capacity exceeds the capacity required for the movement ofirrigation water.

6

Irrig tio11Water Su1>ply

The irrigation water is supplied from ground water wells, internal lakes, and from the St. Lucie (SFWMD C-44) Canal. A pump station at the C-44 delivers water to Unit 2, then on to Unit 3, and lastly, northward into Unit JA. Refer to the Water Control Plans for Unit of Development Nos. I, 2 and 3 aJtd the South Florida Water Management District Water Use Permit No. 43-OO0S7-W for existing well locations and capacities (see Exhibit 6), under this plan two (2) existing wells are for supplemental golf course iJ.1·igation water and will remain.

HSLCD has an irrigation supply pump station on 1h.e St. Lucie (C-44) Canal. This pump station is only used for nTigation supply and has no drainage function. The St. Lucie Canal's water source is water from Lake Okeech.obee (and localized drainage). The pump station design criteria was to provide ap}X'oximately 1/ 4 inch of water per day to the HSLCD.

cl.	Levee Flood Protection

The entire area of the HSLCD, comprising ofbothim:proved and unimproved lands, is enclosed by an outside levee (berm) which prevents a11y flow of smface waters onto any lands withinHSLCD.

ID.	Water Control Plan Improvements

Surface Water Management System Imp:rovements

Descri1Jtio11 ofl01p1·ovements/Unit of Development No. IA

The property has been utilized for citrus _produotion for se-veral decades. Most recently the property has partially developed twenty acre lots wilh supp011ing polo facilities. The property contains no native wetlands or upland habitat.

The property is located totally withiJ.1 the Hobe-St. Lucie Conservancy District Unit 1 and contaiJ.1s perimeter agricultural canals and a telocatable drainage easement wlu.ch are dedicated to and maintained by the Hobe-St Lucie Conservancy District.

.   Internal Lake System

This Plan provides for the construction of facilities 10 support the new development including a system of lakes and pipe structures. TI1ese ntodifications shall also include the ccmstruction of ancillary drainage structures, outfalls, and. appmtenances..

The final configuration of lakes may vary based on actual site conditions and as the final site design warrants.

Atlantic Ridge ]?reserve State Park Improvements

Prut of the proposed water management plan is to impro"Ve tl1e conveyance and discharge of the Atlantic Ridge Preserve State Park (ARPSP) n:moff. The project proposes
.improvements of the conveyance system located along the eastern property line of the District. The project also includes t11e reconstruction of the n01them relief canal and outfall, as well as construction of a restored wetland flow tlir01Lghmarsh into the Robe St Lucie Conservancy District Outfall Canal (see ExbibiH-1).

Outfall Canals and Discharge Control Strmtures

HSLCD has three discharge strnctures. These structrues shall remain in place and shall discharge to the South Fork of the St. Lucie River (lJnit 1 Outfall) and the other two discharge to the Loxahatchee River via the Cypress Creek and Gulfstream Canal. Generally, lands 110:rfu of Bridge Road drain to the Smith Fork of the St. Lucie River and lands south of Bridge Road drain to the Loxahatchee Ri\rer.

Excess storm water flow from the Unit IA lmds will becol!ected and conveyed, via swales, to interconnected lake then on to the Unit 1 Outfall Canal Tiie Outfall Canal locations are shown on Exhibit 5. All of the facilities are considered coIDU1011 to all of HSLCD. Flows in these canals are regulated by water control structures that are descdbed as follows:

Unit of Development No. 1 Outfall Structure, which discharges to the South Fork of the St. Lucie River, serves the area referred to as Unit of Developinent No. 1 and the offsite lands south, north and east of HSLCD. The structure has a steel pile wall across the caual with concrete discharge bays. here are 3 discharge bays, 4 feet 6 inches wide, with a concrete sill at elevation 2.0 Feet NGVD. Stop logs can be placed in these bays to va1y the water elevation upstream of the structure. There are two (2) overflow weirs, 5 feet 6 inches wide, at elevation 10.0 Feet NGVD on each side of the discharge bays. There is a concrete cap across the structure at elevation 14.5 Feet NGVD. This replaced the original structure and was constructed in 1993.

There is an Outfall Control Structure fo· the golf course at the north end of the golf course. This outfall structure is manual as operated by the HSLCD personnel and maintained by
8

HSLCD at thei.r discretion. The structure is detailed in SF'WMD ERP Permit Nuu1ber 43-
02812-P.

Minor, insubstantial Amendments include Amendments to the Plan, which replace, relocate, reconstruct, or improve an upgrade in District facilities and operations consistent with the adopted Plan, which do not require increasing assessments beyond the maximum authorized by law, or amendments to engineers repotts which do not increase the total assessment of benefits.

I fwther ceitify that in accordance with the provisions of Chapter 99-473, Laws of Florida, that al I land benefited by the improvements provided for in the original Plan receives the same or greater benefits as previously assessed and that the estimated cost of imple1nenting the Plan, as amended, does not exceed the total benefits assessed in th rovidod by law.
