Summary
The Modified Water Deliveries Project (Mod Waters) is a controversial ecological
restoration project in south Florida designed to improve water delivery to Everglades
National Park. The implementation schedule of Mod Waters is of interest to Congress
partly because its completion is required before the implementation of portions of the
Comprehensive Everglades Restoration Plan. Concerns have been raised in hearings on
the Administration’s FY2006 budget request regarding the cost of implementing the
project and the U.S. Army Corps of Engineers’ authority to fund the project. Further,
due to concerns regarding phosphorus pollution in the Everglades, Congress enacted a
provision in the FY2004 and FY2005 Interior Appropriations Acts that conditions
funding for Mod Waters on meeting state water quality standards. In addition, the use
of eminent domain to acquire land for a flood control plan adjacent to the park has been
controversial. Several landowners who were unwilling to sell their land obtained a
ruling in federal court that prevented further land acquisitions in the area. The Corps
appealed this decision, and Congress authorized a plan, which included land acquisition,
in the Consolidated Appropriations Resolution for FY2003. This report provides
background on Mod Waters and discusses issues relating to its current status, funding,
and land acquisition needs. This report will be updated as warranted.
Most Recent Developments
The Modified Waters Deliveries Project (Mod Waters) is being implemented by the
Department of the Interior and the U.S. Army Corps of Engineers in southern Florida.
(See Figure 1.) For FY2006, the Administration has requested a total of $60 million for
the project: $35 million through the Corps and $25 million through the Department of the
Interior. The President’s request for the Everglades has drawn attention because of a
proposed change in the funding of Mod Waters. The request called for the Corps to
broaden its role by jointly funding the project with the Department of Interior, which
previously had solely funded the project. This proposal has raised a question: Is the Corps
authorized to receive appropriations to work on the project? The Administration’s

position appears to be for the Corps to pay for roughly two-thirds of the remaining $191
million required to complete the project during next four fiscal years (FY2006-FY2009).1
A provision in the Consolidated Appropriations Act for FY2005 (P.L. 108-447)
conditions funding for Mod Waters on meeting state water quality standards. This
provision cites provisions in the FY2004 Interior Appropriations Act, which states that
funds appropriated for Mod Waters will be provided unless the Secretary of the Interior,
Secretary of the Army, Administrator of the EPA, and Attorney General indicate in a joint
report (to be filed annually until December 31, 2006) that water entering the A.R.M.
Loxahatchee National Wildlife Refuge and Everglades National Park does not meet state
water quality standards, and the House and Senate Committees on Appropriations respond
in writing disapproving the further expenditure of funds.2
To help implement Mod Waters, Congress included a provision in the Consolidated
Appropriations Resolution for FY2003 (Division F, Title I, §157 of P.L. 108-7) that
authorizes the Corps to implement a flood protection plan (Alternative 6D) for the “8.5
Square Mile Area”(8.5 SMA) as part of Mod Waters. Three conditions are specified in
the section authorizing implementation of Alternative 6D: (1) the Corps may acquire
residential property needed to carry out Alternative 6D if the owners are first offered
comparable property in the 8.5 SMA that will be provided with flood protection; (2) the
Corps is authorized to acquire land from willing sellers in the flood-protected portion of
the 8.5 SMA to carry out the first condition; and (3) the Corps and the nonfederal sponsor
may carry out these provisions with funds provided under the Everglades National Park
Protection and Expansion Act of 1989 (P.L. 101-229; 16 U.S.C. §410r-8) and funds
provided by the DOI for land acquisition for restoring the Everglades.
Background
The Modified Water Deliveries Project was authorized by the Everglades National
Park Protection and Expansion Act of 1989 (P.L. 101-229) to improve water deliveries
to Everglades National Park and, to the extent possible, restore the natural hydrological
conditions within the park. The completion of Mod Waters is expected to be a central
part of the Comprehensive Everglades Restoration Plan (CERP; Title VI, P.L. 106-541,
the Water Resources Development Act of 2000 [WRDA 2000]).3
Mod Waters is expected to consist of structural modifications and additions to the
Central and Southern Florida Project (C&SF Project) to improve the timing, distribution,
and quantity of water flow to the Northeast Shark River Slough.4 Increased water flow

to the Northeast Shark River Slough will increase water supplies in the park and is
expected to improve the natural habitat and hydrology of a portion of the Everglades
ecosystem.5

Mod Waters is expected to flood some residential and agricultural areas adjacent to
the park. Legislation authorizing this project instructs the Secretary of the Army to
determine if residential and agricultural areas within or adjacent to the 8.5 SMA will be
flooded from the hydrological changes of Mod Waters (§104(a)). If these areas are under
threat of flooding, the law mandates that a flood protection system must be developed for
the area (§104(b)). To prevent flooding, several mitigation features have been developed.
One of these features is called Alternative 6D, which is a plan for protecting residents in
the 8.5 SMA from flood waters resulting from the project (discussed further below).
The importance of Mod Waters goes beyond its expected direct results. Legislation
authorizing CERP provides that the Mod Waters must be completed before several CERP
projects involving water flows on the east side of the park can receive appropriations
(§601(b)(2)(D)(iv) of WRDA 2000).

land for agriculture, and provide water supplies to urban areas. The cornerstone of this effort was
the Central and Southern Florida Project, which was authorized by the Flood Control Project Act
of 1948 (ch. 771, 62 Stat. 1171). This project resulted in nearly 1,000 miles of canals, 720 miles
of levees, and more than 200 water control structures (e.g., dikes, dams and pumping stations).

Issues Surrounding the Modified Water Deliveries Project
Three issues are being debated about the implementation of Mod Waters, including
its estimated funding level, the relevance of its completion to overall restoration efforts
in the Everglades, and the controversy surrounding land acquisition in the 8.5 SMA.
Funding. Rising project costs for Mod Waters led some critics to question its
viability. The original cost of completing Mod Waters was estimated at $81.3 million in
1990.6 The current estimated cost for completing the project is $398 million.7 To date,
approximately $192 million has been appropriated for constructing and implementing
Mod Waters, and $206 million more is estimated to be needed to finish the project (i.e.,
FY2005-FY2009).8 Some supporters of Mod Waters argue that changes in the
implementation plan, the rising cost of land acquisition, and flood mitigation
requirements have led to higher costs. This was reflected, according to some, in the
changes in the 1992 General Design Memorandum, which were derived from improved
modeling data and the project’s need to be compatible with CERP.
Project Delays. Mod Waters was originally estimated to be completed by 1997,
yet now some argue it is unclear as to when or even whether the project will be
completed. The FY2006 Administration request indicates that funding will be requested
through FY2009. Some argue that the delay in implementing Mod Waters jeopardizes
implementation of CERP projects, causes further degradation within Everglades National
Park, and will set a precedent for delays and deliberation regarding land acquisition
activities when CERP projects are being implemented. Section 601(b)(2)(D)(iv) of
WRDA 2000 provides that Mod Waters must be completed before appropriations can be
made to construct other restoration projects in the east Everglades.
Land Acquisition in the 8.5 Square Mile Area. Implementation of Mod
Waters was dependent on acquiring land in the 8.5 SMA. Land acquisition in this area
was controversial because there were several unwilling sellers and the Corps had to
exercise eminent domain to acquire the necessary lands.
The 8.5 SMA is a region adjacent to Everglades National Park of approximately
5,600 acres with a residential community of approximately 1,500 people. Due to its low
topography (ranging from 5.0 to 8.5 feet NGVD9) and lack of drainage, parts of the 8.5
SMA frequently flood for several months during the rainy season (typically from May to
October). With the implementation of Mod Waters, the Corps expected that most of the
8.5 SMA would flood. The Corps developed a flood mitigation plan in 1992 (the 1992

construction, design, and monitoring, among other things.

General Design Report and EIS for Modified Water Deliveries to Everglades National
Park [1992 Plan]). The 1992 Plan was expected to provide flood control for residents in
the 8.5 SMA and allow for the implementation of Mod Waters. However, the 1992 Plan
was later deemed “unworkable” by the superintendent of Everglades National Park, who
claimed that it would not provide full flood protection for current and future residents in
the 8.5 SMA.10
The Corps began to devise a new plan for Mod Waters and the 8.5 SMA in 1999,
which considered several alternative plans, including the complete buyout of the 8.5
SMA. A new plan, referred to as Alternative 6D, was proposed by the Corps in 2000.
This plan includes a perimeter levee, seepage canal, pump station, and storm water
drainage for flood protection in the 8.5 SMA. Instead of a complete buyout of the 8.5
SMA, this plan proposed the acquisition of approximately 2,100 acres in the 8.5 SMA
(39% of the total area) and the removal of 77 residential tracts (24 tenant-occupied tracts
and 53 owner-occupied tracts) in the 8.5 SMA (13% of the total number of “residential
areas” in the 8.5 SMA).11 Properties of the remaining families would receive flood
control.12
On February 23, 2001, some residents who are unwilling to sell their land in the 8.5
SMA filed a case against the Corps with two complaints. They asserted that the Corps
does not have the authority to implement a plan that does not protect the entire 8.5 SMA
from flooding, and that the Corps does not have the authority to exercise eminent domain
or spend money to acquire their land through condemnation.13 On July 5, 2002, a district
judge adopted an earlier ruling by a federal magistrate that restricted the Corps from
veering from its original mandate to protect the entire community from flooding, and
prevented the Corps from acquiring land in the 8.5 SMA. The Corps appealed this
decision to the U.S. Court of Appeals for the Eleventh Circuit on September 4, 2002, and
Congress authorized implementation of the Alternative 6D plan in the Consolidated
Appropriations Resolution for FY2003.
Some critics of land acquisition in the 8.5 SMA base their arguments on the same
principles used to criticize the acquisition of the entire 8.5 SMA — that the federal
government should not exercise eminent domain to remove unwilling sellers and that the
federal government is obligated to protect all residential areas from floods under P.L. 101-
229. Some critics also argue that there are several unwilling sellers in the area and that
if condemnations proceed, delays due to litigation will be inevitable and will eventually

harm the ecosystem.14 Some supporters of acquiring land in the 8.5 SMA and
implementing Alternative 6D argue that if this plan is not implemented, delays may be
even longer in implementing Mod Waters and restoring the regional ecosystem, to the
detriment of Everglades National Park.
The use of condemnation by the Corps to acquire lands is controversial. Some critics
assert that the Corps should not use eminent domain to acquire lands in the 8.5 SMA from
unwilling sellers, and that the Corps may not have the authority to use condemnation.15
The Corps asserts that it has the authority to condemn lands if necessary, and furthermore
that there are several willing sellers in the 8.5 SMA.16

A21.
15 A provision in the FY2005 Consolidated Appropriations Law (P.L. 108-447; §329), requires
that no funds appropriated for acquiring lands may be expended for the filing of declarations of
taking or complaints in condemnation without the approval of the House and Senate Committees
on Appropriations. An exception to this provision is funds appropriated to implement the
Everglades National Park Protection and Expansion Act of 1989, or to funds appropriated for
federal assistance to the State of Florida to acquire lands for Everglades restoration purposes.
16 The Corps asserts its power for condemnation is authorized under 40 U.S.C. §257 and 33
U.S.C. §591. This authority is extended to practices of flood control under 33 U.S.C. §701
according to the Corps. Personal communication with Barry Vorse, U.S. Army Corps of
