COMMITTEE SUBSTITUTE - Substantial Changes 
 
I. Summary: 
CS/CS/SB 492 provides a standardized schedule for releasing mitigation credits and removes the 
requirement that the Department of Environmental Protection (DEP) and water management 
districts determine the credit release schedule on a case-by-case basis pursuant to statutorily 
enumerated factors.  The bill provides that credits must be released as follows: 
• 30 percent upon recording a conservation easement and establishing financial assurances (or 
100 percent for preservation-only banks). 
• 30 percent after completing initial construction activities. 
• 20 percent upon meeting interim performance criteria. 
• 20 percent upon meeting final success criteria. 
 
Additionally, the bill allows freshwater wetland creation credits to be released before all the 
success criteria have been met. Only success criteria for initial construction success criteria need 
to be met.   
 
The bill provides that permit applicants are entitled to a one-time use of credits from a mitigation 
bank outside the mitigation bank service area when an insufficient number or type of credits are 
available within the impacted area. The DEP or a water management district must have 
determined that the mitigation service area lacked the appropriate credit type and the 
implementation of permittee-responsible mitigation was not sufficient to offset impacts before 
REVISED:   BILL: CS/CS/SB 492   	Page 2 
 
approving credits outside the service area. The bill provides that the following multipliers would 
apply to credits outside the service area: 
• 1.0 multiplier for use of in-kind credits within the service area. 
• 1.0 multiplier for use of in-kind and out-of-service-area credits when the service area 
overlays part of the same regional watershed as the proposed impacts only after credit-
deficiency has been established. 
• 1.2 multiplier for use of in-kind and out-of-service-area credits located within a regional 
watershed immediately adjacent to the regional watershed overlain by a mitigation bank 
service area in which proposed impacts are located only after credit-deficiency has been 
established only after credit-deficiency has been established. 
• When in-kind credits are not available to offset impacts in the regional watershed 
immediately adjacent to the regional watershed overlain by a bank service area in which the 
proposed impacts are located, an additional 0.25 multiplier shall be applied for each 
additional regional watershed boundary crossed. 
• An additional 0.50 multiplier shall be applied if the mitigation used to offset impacts entails 
an out-of-kind replacement. 
 
The bill provides that use of these multipliers meets the requirements for addressing cumulative 
impacts.  
 
Once the amount of mitigation required to offset impacts is determined, the DEP or water 
management district must contact all mitigation banks with a service area encompassing the 
location of the proposed impacts within seven days to verify the availability of credits. The 
mitigation banks have 15 days to respond; if no response is received, it is presumed credits from 
that bank are not available. The DEP or water management district must then notify the permit 
applicant if sufficient credits are available. The bill also requires mitigation banks to submit 
annual reports detailing the number and type of available credits for sale. The DEP and water 
management districts must compile these reports and provide an annual assessment of the state’s 
mitigation banking system to the Legislature. 
 
The bill has no impact on state revenues or expenditures. See Section V., Fiscal Impact 
Statement. 
 
The bill has an effective date of July 1, 2025. 
II. Present Situation: 
Environmental Resource Permits (ERP) 
Part IV of ch. 373, F.S., and ch. 62-330, F.A.C., regulate the statewide ERP program, which 
governs the construction, alteration, operation, maintenance, repair, abandonment, and removal 
of stormwater management systems, dams, impoundments, reservoirs, appurtenant works, and 
other works such as docks, piers, structures, dredging, and filling located in, on, or over wetlands  BILL: CS/CS/SB 492   	Page 3 
 
or other surface waters.
1
 ERP applications are processed by either the Department of 
Environmental Protection (DEP) or one of Florida’s five water management districts.
2
 
 
Permit applicants must demonstrate that the regulated activity will not be harmful to the water 
resources or will not be inconsistent with the overall objectives of the water management 
district.
3
 Applicants must provide reasonable assurance that state water quality standards will not 
be violated and that the proposed activity is not contrary to the public interest.
4
 If a proposed 
activity significantly degrades or is within an Outstanding Florida Water,
5
 the applicant must 
provide reasonable assurance that the proposed activity will be clearly in the public interest.
6
 In 
determining whether an activity is contrary to the public interest or clearly in the public interest, 
the water management district or the DEP must consider and balance the following criteria: 
• Whether the activity will adversely affect the public health, safety, or welfare or the property 
of others; 
• Whether the activity will adversely affect the conservation of fish and wildlife, including 
endangered or threatened species, or their habitats; 
• Whether the activity will adversely affect navigation or the flow of water or cause harmful 
erosion or shoaling; 
• Whether the activity will adversely affect the fishing or recreational values or marine 
productivity in the vicinity of the activity; 
• Whether the activity will be of a temporary or permanent nature; 
• Whether the activity will adversely affect or will enhance significant historical and 
archaeological resources; and 
• The current condition and relative value of functions being performed by areas affected by 
the proposed activity.
7
 
 
If the applicant is unable to otherwise meet this criteria, the DEP or the governing board of a 
water management district, in deciding to grant or deny a permit, must consider measures 
proposed by or acceptable to the applicant to mitigate adverse effects of the regulated activity.
8
 
Such measures may include onsite mitigation, offsite mitigation, offsite regional mitigation, and 
the purchase of mitigation credits from mitigation banks.
9
  
 
In deciding whether to grant or deny a permit for an activity that affects surface waters or 
wetlands, the DEP or the water management district must consider the cumulative impacts of: 
• The proposed activity;

Overview of Mitigation Banking 
Mitigation banking is a practice in which an environmental enhancement and preservation 
project is conducted by a public agency or private entity to provide mitigation for unavoidable 
wetland impacts within a defined mitigation service area.
13
 Mitigation banks are alternative to 
permittee-responsible mitigation.
14
 Permittee-responsible mitigation refers to mitigation 
undertaken by the permittee to provide compensatory mitigation for which the permittee retains 
full responsibility.
15
  
 
In mitigation banking, the bank is the site itself, and the currency sold by the banker to the 
impact permittee is a credit, representing the wetland ecological value equivalent to the complete 
restoration of one acre.
16
 Creation of a mitigation bank in Florida typically requires both a permit 
from the DEP or a water management district and federal approval of a mitigation bank 
instrument from several agencies led by the U.S. Army Corps of Engineers (USACE), in a joint 
state/federal interagency review team.
17
 Requirements for mitigation bank permits differ between 
mitigation bank instruments issued by the USACE and state permits issued by the DEP or the 
water management districts.  
 
The Uniform Mitigation Assessment Method (UMAM) was established as a way to determine 
the amount of mitigation needed to offset adverse impacts to wetlands and other surface waters 
and to award and deduct mitigation bank credits.
18
 The UMAM provides a standardized 
procedure for assessing the ecological functions provided by wetlands and other surface waters, 
 
10
 “Development of regional impact” means any development that, because of its character, magnitude, or location, would 
have a substantial effect upon the health, safety, or welfare of citizens of more than one county. Section 380.06(1), F.S.

the amount that those functions are reduced by a proposed impact, and the amount of mitigation 
necessary to offset that loss.
19
 The  
UMAM evaluates functions through consideration of an ecological community’s current 
condition, hydrologic connection, uniqueness, location, fish and wildlife utilization, and 
mitigation risk.
20
 This standardized methodology is also used to determine the degree of 
improvement in ecological value of proposed mitigation bank activities.
21
 
 
State Mitigation Banking Regulations 
To obtain a mitigation bank permit, the applicant must provide reasonable assurance that the 
mitigation bank will:  
• Improve ecological conditions of the regional watershed;  
• Provide viable and sustainable ecological and hydrological functions for the proposed 
mitigation service area;  
• Be effectively managed in perpetuity;  
• Not destroy areas with high ecological value;  
• Achieve mitigation success; and  
• Be adjacent to lands that will not adversely affect the long-term viability of the mitigation 
bank due to unsuitable land uses or conditions.
22 
 
 
The applicant must also provide reasonable assurances that:  
• Any surface water management system that will be constructed, altered, operated, 
maintained, abandoned, or removed within a mitigation bank will meet ERP requirements 
and related rules;  
• The applicant has sufficient legal or equitable interest in the property to ensure perpetual 
protection and management of the land within a mitigation bank; and  
• The applicant can meet the financial responsibility requirements prescribed for mitigation 
banks.
23 
 
 
Mitigation Bank Credits 
After evaluating the permit application, the permitting agency awards mitigation credits to a 
proposed mitigation bank or phase of such mitigation bank.
24
 The number of credits awarded is 
based on the degree of improvement in ecological value expected to result from the 
establishment and operation of the mitigation bank as determined using a functional assessment 
methodology.
25
 In determining the degree of improvement in ecological value, specific factors 
must be evaluated, including, among other things, the ecological and hydrological relationship

between wetlands and uplands in the mitigation bank and the proximity of the mitigation bank to 
areas with regionally significant ecological resources or habitats, and the extent to which the 
mitigation bank provides habitat for fish and wildlife.
26
 
 
After awarding mitigation credits to a mitigation bank, the permitting agency establishes a 
schedule for the release of those credits in the mitigation bank permit.
27
 A mitigation credit that 
has been released may be sold or used to offset adverse impacts from a regulated activity.
28
 A 
portion of the mitigation credits can be released for sale or use prior to meeting all the 
performance criteria specified in the mitigation bank permit.
29
 However, the permitting agency 
will only release the full amount of awarded credits after all success criteria are met.
30
 
 
The permitting agency determines the number of credits and schedule for release based on the 
performance criteria for the mitigation bank and the success criteria for each mitigation 
activity.
31
 The release schedule for a specific mitigation bank or phase thereof is related to the 
actions required to implement the bank, such as site protection, site preparation, earthwork, 
removal of wastes, planting, removal or control of nuisance and exotic species, installation of 
structures, and annual monitoring and management requirements for success. In determining the 
specific release schedule for a bank, the permitting agency must consider, at a minimum, the 
following factors: 
• Whether the mitigation consists solely of preservation or includes other types of mitigation. 
• The length of time anticipated to be required before a determination of success can be 
achieved. 
• The ecological value to be gained from each action required to implement the bank. 
• The financial expenditure required for each action to implement the bank.
32
 
 
However, no credit can be released for freshwater wetland creation until the success criteria 
included in the mitigation bank permit are met.
33
 
 
Mitigation Service Area 
During the permitting of a mitigation bank, the permitting agency (the DEP or a water 
management district) determines the mitigation service area, which is the geographic region 
within which the bank could reasonably be expected to offset impacts.
34
 In determining the 
boundaries of the mitigation service area, the permitting agency must consider the 
characteristics, size, and location of the mitigation bank and, at a minimum, the extent to which 
the mitigation bank: 
• Contributes to a regional integrated ecological network;

• Will significantly enhance the water quality or restoration of an offsite receiving water body 
that is designated as an Outstanding Florida Water, a Wild and Scenic River, an aquatic 
preserve, a water body designated in a plan approved pursuant to the Surface Water 
Improvement and Management Act, or a nationally designated estuarine preserve; 
• Will provide for the long-term viability of endangered or threatened species or species of 
special concern; 
• Is consistent with the objectives of a regional management plan adopted or endorsed by the 
department or water management districts; and 
• Can reasonably be expected to offset specific types of wetland impacts within a specific 
geographic area. A mitigation bank need not offset all expected impacts within its service 
area.
35
 
 
The DEP and the water management districts use regional watersheds to guide the establishment 
of mitigation service areas.
36
 A mitigation service area may extend beyond the regional 
watershed in which the bank is located into all or part of other regional watersheds when the 
mitigation bank has the ability to offset adverse impacts outside that regional watershed.
37
 
Similarly, a mitigation service area may be smaller than the regional watershed in which the 
mitigation bank is located when adverse impacts throughout the regional watershed cannot 
reasonably be expected to be offset by the mitigation bank because of local ecological or 
hydrological conditions.
38
 
 
In general, mitigation credits may only be used to offset adverse impacts in the mitigation service 
area.
39
 However, if certain requirements are met, the following projects may be eligible to use a 
mitigation bank regardless of whether they are located within the mitigation service area: 
• Projects with adverse impacts partially located within the mitigation service area. 
• Linear projects, such as roadways, transmission lines, distribution lines, pipelines, railways, 
or certain seaports. 
• Projects with total adverse impacts of less than one acre in size.
40
 
 
Federal Mitigation Banking Regulations  
For projects requiring a federal permit, a USACE district engineer determines the mitigation to 
be required in a mitigation bank permit based on what is practicable and capable of 
compensating for the aquatic resource functions that will be lost as a result of the permitted 
activity.
41
 When evaluating options for mitigation, the USACE considers the type and location 
options in the following order (commonly referred to as the mitigation preference hierarchy): 
• Mitigation bank credits;

• In-lieu fee program credits;
42
 
• Permittee-responsible mitigation under a watershed approach;
43
 
• Permittee-responsible mitigation through on-site and in-kind
44
 mitigation; or 
• Permittee-responsible mitigation through off-site and/or out-of-kind
45
 mitigation.
46
 
 
In general, the required mitigation should be located within the same watershed as the impact site 
and where it is most likely to successfully replace lost functions and services, taking into account 
watershed scale features as aquatic habitat diversity, habitat connectivity, relationships to 
hydrologic sources, trends in land use, ecological benefits, and compatibility with adjacent land 
uses.
47
 When compensating for impacts to marine resources, the location of the mitigation site 
should be chosen to replace lost functions and services within the same marine ecological system 
(e.g., reef complex, littoral drift cell).
48
 Compensation for impacts to aquatic resources in coastal 
watersheds should also be located in a coastal watershed where practicable.
49
  
 
Mitigation Bank Credits  
When permitted impacts are located within the service area of an approved mitigation bank, and 
the bank has the appropriate number and resource type of credits available, the permittee’s 
compensatory mitigation requirements may be met by securing those credits from a mitigation 
bank.
50
 An approved instrument (including an approved mitigation plan and appropriate real 
estate and financial assurances) must be in place before credits can be used to compensate for 
authorized impacts.
51
 Mitigation bank credits are not released until specific milestones associated 
with the mitigation bank site’s protection and development are achieved.
52
 
 
If the USACE determines that mitigation is necessary to offset unavoidable impacts to aquatic 
resources, the amount of required mitigation must be, to the extent practicable, sufficient to 
replace lost aquatic resource functions.
53
 The USACE requires a mitigation ratio greater than 
one-to-one where necessary to account for (1) the distance between the affected aquatic resource 
and the compensation site, (2) the method of mitigation (e.g., preservation), (3) the likelihood of 
success, (4) differences between the functions lost at the impact site and the functions expected 
 
42
 An in-lieu fee program is a program involving the restoration, establishment, enhancement, and/or preservation of aquatic 
resources through funds paid to a governmental or non-profit natural resources management entity to satisfy compensatory 
mitigation requirements for DA permits. Similar to a mitigation bank, an in-lieu fee program sells compensatory mitigation 
credits to permittees whose obligation to provide compensatory mitigation is then transferred to the in-lieu program sponsor. 
However, the rules governing the operation and use of in-lieu fee programs are somewhat different from the rules governing 
operation and use of mitigation banks. 33 C.F.R. 332.2. 
43
 Permittee-responsible mitigation means an aquatic resource restoration, establishment, enhancement, and/or preservation 
activity undertaken by the permittee (or an authorized agent or contractor) to provide compensatory mitigation for which the 
permittee retains full responsibility. 33 C.F.R. 332.2. 
44
 In-kind means a resource of a similar structural and functional type to the impacted resource. 33 C.F.R. 332.2. 
45
 Out-of-kind means a resource of a different structural and functional type from the impacted resource. 33 C.F.R. 332.2.

and/or (5) the difficulty of restoring or establishing the desired aquatic resource type and

54
  
 
Mitigation Service Area 
Under federal law, the mitigation service area is the watershed, ecoregion,
55
 physiographic 
province, or other geographic area within which the mitigation bank is authorized to provide 
compensatory mitigation required by USACE permits.
56
 The service area must be appropriately 
sized to ensure that the aquatic resources provided will effectively compensate for adverse 
environmental impacts across the entire service area.
57
 For example, in urban areas, a U.S. 
Geological Survey 8-digit hydrologic unit code (HUC)
58
 watershed or a smaller watershed may 
be an appropriate service area.
59
 In rural areas, several contiguous 8-digit HUCs or a 6-digit 
HUC watershed may be an appropriate service area.
60
 Delineation of the service area must also 
consider any locally-developed standards and criteria that may be applicable.
61
 The economic 
viability of the mitigation bank may also be considered in determining the size of the service 
area.
62
 
 
USACE Proximity Factor Tool 
The USACE developed a proximity factor tool that may be used when there are insufficient 
mitigation credits within the approved mitigation bank service area. The tool is used to assess the 
number of credits required for any compensatory mitigation proposed outside of approved 
mitigation bank service areas.
63
 The proximity factor is based on ratio multipliers for multiple

 Ecoregions are areas where ecosystems (and the type, quality, and quantity of environmental resources) are generally 
similar. A Roman numeral classification scheme has been adopted for different hierarchical levels of ecoregions, ranging 
from general regions to more detailed: Level I - 12 ecoregions in the continental U.S.; Level II - 25 ecoregions in the 
continental U.S.; Level III -105 ecoregions in the continental U.S.; Level IV - 967 ecoregions in the conterminous U.S. EPA,

 “HUC” means the hydrologic cataloging unit assigned to a geographic area representing a surface watershed drainage basin. 
Each unit is assigned a two- to 12-digit number that uniquely identifies each of the six levels of classification within six two-
digit fields. United States Geological Survey (USGS), Hydrologic Unit Codes (HUCs) Explained , 
https://nas.er.usgs.gov/hucs.aspx (last visited Mar. 3, 2025). Eight-digit HUCs are used for large watersheds known as 
subbasins; 10-digit HUCs divide the large subbasins into watersheds; and 12-digit HUCs divide watersheds into subwatersheds 
that capture local tributary systems. EPA, Hydrologic Unit Codes: HUC 4, HUC 8, and HUC 12, available at

variables.
64
 The tool is only applied when the USACE has determined that mitigation outside of 
the approved mitigation service area is the most environmentally preferable mitigation option.
65
 
 
The proximity factor tool applies the following multipliers: 
• No multiplier if the impact site is outside of a mitigation bank service area boundary, but 
within the same 8-digit HUC that contains the mitigation bank location. 
• 1.5 multiplier if the impact site is outside of a mitigation bank service area boundary and one 
8-digit HUC away from the mitigation bank service area boundary. 
• 0.25 multiplier for each additional 8-digit HUC away from the mitigation bank location. 
• 0.75 multiplier if mitigation entails out-kind replacement (there is no multiplier if the 
mitigation entails in-kind replacement). 
• 0.25 multiplier if mitigation occurs within a different EPA Level IV Ecoregion.
66
 
 
The sum of the applicable multipliers provides the proximity factor.
67
 The resulting proximity 
factor is then multiplied by the number of credits required by the USACE to compensate for 
unavoidable adverse effects to aquatic resources (e.g., via application of an approved functional 
assessment such as UMAM).
68
 The USACE has the discretion to consider and approve use of the

Mitigation should be performed within the same 6-digit HUC.
70
 When assessing the location of 
the mitigation site relative to the impact site, the calculation starts at the 8-digit HUC that 
contains the mitigation bank site.

III. Effect of Proposed Changes: 
Section 1 amends s. 373.4136, F.S., regarding the establishment and operation of mitigation 
banks. Currently, the Department of Environmental Protection (DEP) and the water management 
districts are authorized to set the schedule for releasing mitigation credits to each mitigation bank 
on a case-by-case basis based on the performance criteria for the mitigation bank, the success 
criteria for each mitigation activity, and other enumerated factors.
72
  
 
The bill requires the DEP and the water management districts, after July 1, 2025, to adhere to the 
following credit release schedule:

 Section 373.4136(5)(b), F.S. The factors include (1) whether the mitigation consists solely of preservation or includes other 
types of mitigation; (2) the length of time anticipated to be required before a determination of success can be achieved; (3) 
the ecological value to be gained from each action required to implement the bank; and (4) the financial expenditure required 
for each action to implement the bank. Id.  BILL: CS/CS/SB 492   	Page 11 
 
• 30 percent of awarded credits upon the recordation of the conservation easement and 
establishment of financial assurances required by the mitigation bank permit. If a 
preservation-only assessment area is used, 100 percent of awarded credits must be released 
for the recordation of the conservation easement and establishment of financial assurances 
required by the mitigation bank permit.  
• 30 percent of awarded credits following completion of initial construction activities as 
established by the mitigation bank permit. 
• 20 percent of awarded credits in increments as monitoring indicates interim performance 
criteria established by the mitigation bank permit are being met. 
• 20 percent of awarded credits upon meeting final success criteria established by the 
mitigation bank permit 
 
The bill provides that the mitigation bank applicant may propose an alternative credit release 
schedule, and the DEP or water management district must consider the proposed alternative 
credit release schedule. Upon request by a mitigation bank permittee for modification of the 
credit release schedule of a permitted mitigation bank, the DEP or water management district 
must modify the credit release schedule to conform it to the bill’s credit release schedule if such 
permitted mitigation bank has not yet had mitigation credits released for the completion of 
construction activities. The DEP or water management district may not alter, change, or modify 
any other provision of the mitigation bank permit unrelated to the credit release schedule. 
 
Currently, credits cannot be released for freshwater wetland creation until the success criteria 
included in the mitigation bank permit are met. The bill allows these types of credits to be 
released sooner, after the success criteria for initial construction activities are met. 
 
The bill provides that once a mitigation bank service area has been established by the DEP or a 
water management district, such service area must be considered to have met the cumulative 
impact requirements of s. 373.414(8)(a), F.S.,
73
 for impacts permitted within any regional 
watershed included in the mitigation bank service area. 
 
The bill provides that, when the provisions of s. 373.414(1)(b) and (8), F.S., are met and an 
insufficient number or type of credits from banks whose permitted service area overlays in whole 
or in part the regional watershed in which the impacts occur, the permit applicant is entitled to a 
one-time use of credits released from a mitigation bank outside the mitigation bank service area 
to offset impacts. The DEP or water management district must have determined that the 
mitigation service area lacked the appropriate credit type and the implementation of permittee-
responsible mitigation was not sufficient to offset impacts associated with the proposed project. 
Priority must be given to mitigation banks whose permitted service area fully includes the 
impacted site. 
 
 
73
 Section 373.414(8)(a), F.S., provides that, in deciding whether to grant a permit for an activity that affects surface waters 
or wetlands, the permitting agency must consider the cumulative impacts of (1) the proposed activity; (2) other projects that 
already exist, are under construction, or have applied for permits or formal wetland or surface water determinations; and (3) 
activities related to developments of regional impact  which are under review, approved, or vested, or other activities 
regulated under Part IV of chapter 373, F.S., which may reasonably be expected to be located within surface waters or 
wetlands in the same drainage basin based upon a local government’s comprehensive plans.  BILL: CS/CS/SB 492   	Page 12 
 
The bill provides that, if the number of released credits within a mitigation service area only 
partially offsets the impacts associated with a proposed project in that mitigation service area, the 
project applicant may use out-of-service area credits to account for the difference between the 
released credits available in the mitigation bank service area and the credits required to offset the 
impacts associated with the proposed project. The bill requires the DEP and the water 
management districts to follow the following guidelines to apply a proximity factor to determine 
adequate compensatory mitigation as follows: 
• A 1.0 multiplier shall be applied for use of in-kind credits within the service area. 
• A 1.0 multiplier shall be applied for use of in-kind and out-of-service-area credits when the 
service area overlays part of the same regional watershed as the proposed impacts only after 
credit-deficiency has been established. 
• A 1.2 multiplier shall be applied for use of in-kind and out-of-service-area credits located 
within a regional watershed immediately adjacent to the regional watershed overlain by a 
mitigation bank service area in which proposed impacts are located only after credit-
deficiency has been established only after credit-deficiency has been established. 
• When in-kind credits are not available to offset impacts in the regional watershed 
immediately adjacent to the regional watershed overlain by a bank service area in which the 
proposed impacts are located, an additional 0.25 multiplier shall be applied for each 
additional regional watershed boundary crossed. 
• An additional 0.50 multiplier shall be applied if the mitigation used to offset impacts entails 
an out-of-kind replacement. 
 
The bill provides that the use of these multipliers meets the requirements for addressing 
cumulative impacts. 
 
The bill provides that, once the amount of mitigation required to offset impacts has been 
determined, and the DEP or water management district determines that out-of-service-area or 
out-of-kind mitigation is necessary, the DEP or water management district must contact all 
mitigation banks within a mitigation service area encompassing the location of the proposed 
impacts within seven business days after the request from the project applicant and request an 
accounting of available credits, including out-of-kind credits. The accounting may not include 
credits reserved for other project applicants. The mitigation banks contacted must provide such 
accounting within 15 business days after the request.  
 
If one or more mitigation banks replying to the request notifies the DEP or the water 
management district that out-of-kind credits are available to offset the proposed impact and the 
DEP or water management district determines that such out-of-kind credits are appropriate to 
offset all or part of the proposed impact, the DEP or water management district must notify the 
permit applicant that sufficient credits are available within that bank’s service area to offset the 
proposed impacts and the use of credits from another mitigation bank outside of that other 
mitigation bank’s service area may not occur until use of all of the out-of-kind credits occurs. If a 
mitigation bank does not reply within the 15 business day timeframe, it is presumed credits from 
that bank are not available. 
 
Upon receipt of the accounting from the mitigation banks, the DEP or the water management 
district must determine if sufficient credits exist to offset impacts associated with the proposed 
project and notify the project applicant of such determination, within 15 business days. The  BILL: CS/CS/SB 492   	Page 13 
 
applicant, and no other entity, may rely on the determination for a period of six months after 
such determination, but only for purposes relating to the pending application producing such 
determination and not any extensions, nor renewals, nor modifications of any permit issued 
pursuant to that pending application, nor for any other permit application. 
 
The bill requires, beginning July 1, 2026, and each July 1 thereafter, each mitigation bank to 
submit an annual report to the DEP or the applicable water management district with an 
accounting of the number and type of credits that the mitigation bank has available for sale, but 
the report may not include names of parties for which credits have been reserved, if any, or the 
contract price paid for such credits. The DEP and each water management district must compile 
such annual reports and provide an annual assessment of this state’s mitigation banking system 
to the Legislature on October 1, 2026, and each October 1 thereafter. 
 
Section 2 provides an effective date of July 1, 2025.

IX. Additional Information: 
A. Committee Substitute – Statement of Substantial Changes: 
(Summarizing differences between the Committee Substitute and the prior version of the bill.) 
CS/CS by Rules on April 21, 2025: 
The committee substitute removes the section on the release of conservation easements. It 
also: 
• Provides that, before out-of-service-area credits are used, the Department of 
Environmental Protection (DEP) or water management district must determine the 
mitigation service area lacks the appropriate credit type and permittee-responsible 
mitigation is insufficient to offset the project’s impacts. 
• Provides that priority must be given to mitigation banks whose permitted service area 
fully includes the impact site. 
• Clarifies that the proximity factor may only be used after credit-deficiency has been 
established. 
• Provides that DEP or water management district must contact mitigation banks for an 
accounting of available credits only after the amount of mitigation required for a 
project has been determined and out-of-service-area or out-of-kind credits is 
determined to be necessary. 
• Provides that if out-of-kind credits are available and appropriate to offset the project’s 
impacts, DEP or the water management district must notify the permit applicant that 
such credits are available; out-of-service area credits may not be used until all the out-
of-kind credits within the service area are used. 
• Extends the deadline for when DEP must contact mitigation banks for an accounting 
of available credits from 3 to 7 days. 
• Provides that, upon request, DEP or water management district must modify a 
permittee’s credit release schedule to conform with the schedule in the bill if 
mitigation credits have not been released for the completion of construction activities. 
• Reduces the timeframe an applicant may rely on the determination of credit 
availability from 1 year to 6 months.  BILL: CS/CS/SB 492   	Page 15 
 
• Clarifies that the presumption that credits are unavailable only applies to credits from 
the bank that failed to reply to DEP’s request for an accounting of credits. 
• Changes the title to land development. 
 
CS by Appropriations Committee on Agriculture, Environment, and General 
Government on April 10, 2025: 
The committee substitute makes the following changes: 
• Allows a mitigation bank applicant to propose to the department or water 
management district an alternative credit release schedule instead of the schedule 
provided in the bill. 
• Clarifies the regional ecological significance of mitigation banks.  
• Reduces the multipliers used when no mitigation credits are available in an impacted 
watershed. 
• Increases the time in which a mitigation bank must respond to a request by DEP or 
water management district for an accounting of available credits and provides that if a 
mitigation bank does not respond within 15 days, it is presumed credits are not 
available.   
• Increases the time in which DEP or water management district must make a 
determination if sufficient credits exist in the impacted area to offset the impacts and 
clarifies that only the permit applicant, and no other entity, can rely on the 
determination.   
• Allows for the release of conservation easements on small, low or non-functioning 
wetlands that are surrounded by development provided the property owner purchases 
sufficient mitigation bank credits to offset the impact.  The process replaces low-
quality wetlands with the preservation of high-quality wetlands and allows the parcel 
to be used for its highest and best use and returned to the tax rolls.
