RESOURCE PROTECTION STANDARDS
Editor's note—Ord. No. 18-001, Pt. A adopted January 23, 2018, repealed the former 6.05.00, §§ 6.05.01—6.05.07, and enacted a 6.05.00 as set out herein. The former 6.05.00 pertained to flood damage prevention and derived from Ord. No. 11-031, adopted December 2, 2011 and Ord. No. 12-010, adopted February 14, 2012.
It is the intent of the Board of County Commissioners to provide for the health, safety, and welfare of the residents of and visitors to St. Lucie County by establishing an administrative review process which encourages preservation of native habitat, and long-term sustainability of our urban forest in accordance with the St. Lucie County Comprehensive Plan and beneficial land and forest management practices by minimizing the unnecessary removal of valuable existing vegetation in advance of approved land development within the unincorporated area of St. Lucie County. Healthy vegetation reduces air and noise pollution, provides for the production of oxygen and sequestering of carbon dioxide, provides energy-saving shade and cooling, furnishes habitat for wildlife, enhances aesthetics and property values, and is an important contributor to community image, pride, and quality of life. In addition, it is the intent of the Board to prevent such destructive land development practices as speculative vegetation removal and clear cutting of land without a site plan or vegetation management and mitigation plan.
A.
The provisions of the following Sections shall supersede the provisions of this Section to the extent of conflict.
1.
Mangrove Protection, Section 6.01.00;
2.
Environmentally Sensitive Lands, Section 6.02.00;
3.
Wetland Protection, Section 6.02.03;
4.

A.
No person shall conduct any vegetation removal activities from or on any lot or parcel of land or portion thereof in the unincorporated area of St. Lucie County without first obtaining a Notice of Vegetation Removal from the Public Works Director, or his/her designee. The Notice of Vegetation Removal application shall be completed in conformance with Section 11.05.06 of this Code. Protected vegetation shall be defined as native vegetation. Types of Notice of Vegetation Removal approval include:
1.
Exemptions. A number of specific activities have been determined to have minimal adverse impact and are listed in Section 6.00.04.
2.
Vegetation Removal Permit. A Vegetation Removal Permit shall be issued if all the criteria set forth in 6.00.05 has been met.
B.
Unless otherwise provided in this Code, all public entities, including all departments of St. Lucie County government, shall be subject to the requirements of this Section. Public entities, however, shall not be subject to:
1.
The application fees under Section 11.12.00 of this Code; or
2.
The penalties under by Section 11.13.03 of this Code.
C.
The provisions of this Section may be suspended or waived by the Public Works Director, or his/her designee during a period of emergency officially declared by the Board of County Commissioners.
D.
The following activities shall require no official notification to the Public Works Director, or his/her designee:
1.
Preserve and Parks Management Activities. Vegetation removal activities associated with an adopted management plan for government maintained parks, recreation areas, wildlife management areas, conservation areas and preserves. The purpose of the vegetation removal activity shall be to protect and preserve the natural values and functions of the ecological communities present, such as, clearing for firebreaks, conducting prescribed burns, or construction of fences.
2.
Existing Agricultural Operations. Vegetation removal, except within required preserve areas or deeded conservation easements, which are part of the on-going activities of the existing agricultural operation, shall not require a permit. Initial clearing of native vegetation on a site shall be preceded by a letter to the Environmental Resources Division. Bona fide agricultural activities include commercial nursery, citrus groves, tree farm, aquaculture, row crops, ranch, or similar operation. When removal of protected vegetation, has been performed under this exemption no development order shall be approved for any other use or improvement, including subdividing, on the same land within four (4) years from the date of the last agricultural classification granted for that land by the St. Lucie County Property Appraiser per F.S. § 193.461. In the event of a hardship such as a natural disaster, the owner may request that the Board of County Commissioners grant a variance from the provisions of this subsection. The Board shall only grant the variance if the Board determines that the owner has presented evidence that the owner has satisfied the standards of Section 10.01.02 of the Land Development Code.
3.
Routine Landscape Maintenance. Trimming or pruning of vegetation which is not intended to result in the eventual death of the vegetation, mowing of yards or lawns, or any other landscaping or gardening activity which is commonly recognized as routine maintenance, replacement or relandscaping which does not result in the eventual death of any vegetation, does not require the approval of a Notice of Vegetation Removal.
Any person who intends to remove or cause the death of any vegetation pursuant to any of the following exemptions must first obtain a Notice of Vegetation Removal from the Public Works Director, or his/her designee or his/her designee. The burden of proving entitlement to any particular exemption shall lie, at all times, with the person or persons claiming the exemption.
A.
The removal of any native vegetation as necessary for the following activities:
1.
The minimal removal of native vegetation necessary for a path not to exceed four (4) feet in width to provide physical access or view necessary to conduct a survey or site examination for the preparation of bona fide site development plans or vegetation inventories; or
2.
The minimal removal of native vegetation necessary for a path not to exceed ten (10) feet in width to provide vehicular access necessary to conduct soil percolation or soil bore tests, provided such clearing or removal is conducted under the direction of Florida registered surveyor or engineer.
B.
The removal of any native vegetation in an existing utility easement, drainage easement, storm water management tract or facility, or right-of-way provided such work is done by or under the control of the operating unit of local, state, or federal government, utility company and that unit of local, state, or federal government or utility company has obtained all necessary licenses or permits to provide service through the easement.
C.
The removal of native vegetation which has been determined to be a safety hazard, destroyed or damaged beyond saving by natural causes or causes not covered by other sections of this chapter, is infected with disease or is infested with insects, or which constitutes immediate peril to life property or other trees, and where pruning or trimming of the vegetation is not able to alleviate the hazard.
D.
The removal of native vegetation, upon any detached single family residential lot or parcel of land having an area of one (1) acre or less. This exemption is, however, subject to the following conditions:
1.
Nothing in this exemption shall exempt any person from the landscaping requirements set forth in Section 7.09.00 of this Code;
2.
This exemption shall not be construed to allow the removal or alteration of any protected vegetation without a Vegetation Removal Permit on any exempted lot or parcel of land by its subdivider unless the subdivider intends in good faith to construct a residential unit or units upon the lot or parcel of land prior to its sale. Advertisement or listing the lot or parcel of land for sale without a residential unit shall create a presumption that the subdivider does not intend to construct such a unit and that the intent is for a subsequent purchaser to develop the lot or parcel.
3.
No native vegetation twenty-four (24) inches, or greater, dbh shall be removed from any residential parcel (including those in the AG-5, AG-2.5, AG-1, AR-1, RE-1, and R/C zoning districts), regardless of parcel size, without an approved Vegetation Removal Permit and an approved mitigation plan. The Public Works Director, or his/her designee may reduce the requirements for mitigation on individual residential lots one-half-acre or less where a protected tree twenty-four (24) inches dbh or greater must be removed in order to provide for the reasonable use of the property.
E.
The removal or alteration of any non-native vegetation.
A.
Removal of Native Vegetation. The Public Works Director, or his/her designee, shall issue a Vegetation Removal Permit only if a completed application has been submitted to the Public Works Director, or his/her designee, and is accompanied by sufficient evidence demonstrating that at least one (1) of the following criteria has been satisfied:
1.
The applicant for a final development order shall demonstrate that the removal of the native vegetation is the minimum necessary in order to implement a Final Development Order and that reasonable efforts have been made to microsite impervious surfaces to protect native vegetation or provide details supporting why preservation of the existing native vegetation is not practically feasible and prevents the reasonable development of the site. The Public Works Director, or his/her designee shall determine the appropriateness of any such claim. The applicant shall provide the Public Works Director, or his/her designee, or his/her designee, a survey of the property outlining the areas of proposed vegetation removal including the location of all vegetation as outlined in Section 11.05.06.
2.
A Final Development Order has not been issued, or is not required by this Code. The applicant for the vegetation removal permit shall demonstrate that the removal of the native vegetation is the minimum necessary in order to allow for the construction of the intended use or improvement of the property and that reasonable efforts have been made to microsite impervious surfaces to protect native vegetation or provide details supporting why preservation of the existing native vegetation is not practically feasible and prevents the reasonable development of the site. The Public Works Director, or his/her designee shall determine the appropriateness of any such claim. The applicant shall provide the Public Works Director, or his/her designee, or his/her designee, a survey of the property outlining the areas of proposed vegetation removal including the location of all vegetation as outlined in Section 11.05.06.
B.
Limiting Removal of Native Vegetation. Prior to the removal of any native vegetation, the removal plan must demonstrate that effective efforts have been made to micro-site impervious surfaces to avoid or minimize impacts to such vegetation.
The extent of approval to remove any native vegetation shall be limited by the Public Works Director, or his/her designee to the minimum necessary to accomplish the purpose of the removal. This may include limiting the extent of approval to portions of a lot or parcel of land or specifying special conditions by which removal shall take place. Such limitation shall be clearly indicated in writing on or attached to the Vegetation Removal Permit. If vegetation removal is limited to a portion of a lot or parcel of land, the extent of such limitation shall be clearly delineated on the face of any site development plans. The application for Vegetation Removal Permit shall demonstrate consistency with the requirements of Section 7.09.03(E)(7).
C.
Vegetation Protection Standards During the Duration of an Approved Notice of Vegetation Removal. The following minimum standards for vegetation protection shall be applied to any area of vegetation designated to be preserved under the terms of an approved Vegetation Removal:
1.
A conspicuous, suitable protective barrier, constructed of metal, wood, safety fencing or other durable material, shall be placed and maintained around the perimeter of the protected area to form a continuous unbroken boundary, around individual protected trees, or groups of protected vegetation, or other protected areas, as follows:
a.
At a minimum distance of twenty-five (25) feet from all jurisdictional wetlands; or
b.
At a minimum distance of ten (10) feet from all required shoreline buffer zones as required in Sections 6.02.01 and 6.02.02.
c.
At a minimum distance of either ten (10) feet from the edge of groups or areas of protected vegetation or from the radius of the dripline from all protected trees, whichever is greater; or
d.
As otherwise provided in special conditions attached to a Notice of Vegetation Removal.
2.
Special care shall be taken that preservation areas are properly marked and highly visible so that equipment operators can see the limits of permitted removal activity.
3.
Protective barriers or protective designations shall remain in place until removal is authorized by the Public Works Director, or his/her designee, or until issuance of a certificate of occupancy or other use authorization as may be granted by the Public Works Director, or his/her designee.
In the event that any protective barriers are removed or altered and clearing activities are conducted within an area identified for preserve under the issued Vegetation Removal Permit, the Public Works Director, or his/her designee is authorized to direct that all land clearing and site alteration work at the site be stopped until the barriers are restored and any necessary corrective actions taken to repair or replant any vegetation removed or damaged as a result of these encroachments.
4.
The entire vegetation preservation area shall be maintained in its natural state so as not to alter the water and oxygen content of the soil and impair its natural function.
5.
No grade changes or excavation of any sort may be made within the vegetation preservation area that require trenching or cutting of roots, except in compliance with the terms of special conditions in an approved Vegetation Removal Permit. If underground utilities must be routed through a protected root zone area, tunneling under the roots shall be required. Irrigation shall be installed outside of the dripline of all protected trees.
These modifications shall be based upon the suggested standards in the latest edition of the "Tree Protection Manual for Builders and Developers" published by the Division of Forestry of the Florida Department of Agriculture and Consumer Services, or a similarly recognized reference manual.
6.
No soil shall be removed from within a vegetation preservation area.
7.
No fill material, construction material, concrete, paint, chemicals, or other foreign materials shall be stored, deposited or disposed of within a vegetation preservation area.
8.
No signs, permits, wires, or other attachments, other than those of protective and non-damaging nature, shall be affixed or attached to protected vegetation.
9.
If landscaping is to be installed within a vegetation preservation area after removal of protective barriers or designations, installation shall be accomplished using hand labor, unless use of light machinery is proven to be necessary and methodology is approved by the Public Works Director, or his/her designee.
10.
Any equipment, including passenger vehicles, shall not be driven, parked, or stored or repaired within designated vegetation preservation areas.
11.
Vegetation destroyed or damaged as part of the development of a site or parcel, shall be replaced by vegetation of equal environmental value as specified by the Public Works Director, or his/her designee, in consultation with the Growth Management Director, before any occupancy or final use permit authorizations are issued.
12.
The authorized removal of any non-protected vegetation in the vegetation preservation area shall be accomplished using hand labor, unless use of light machinery is proven to be necessary and methodology is approved by the Public Works Director, or his/her designee. Only the above ground portions of the non-protected vegetation may be removed and the stump shall be properly treated with an approved herbicide; the root systems of the protected vegetation must remain undisturbed.
13.
If any roots of protected vegetation is exposed or damaged, the applicant shall immediately correct the situation by covering the roots with a high quality of soil to match the existing grades, pruning any splintered roots and providing water until the vegetation has recovered.
14.
The applicant shall provide the Public Works Director, or his/her designee, a written plan to control erosion which may be expected to occur as a result of the proposed removal of protected vegetation. The erosion control plan must be approved by the Public Works Director, or his/her designee, prior to the commencement of any removal of protected vegetation. All provisions of the plan shall be incorporated as express conditions of any Notice of Vegetation Removal issued under this paragraph.
D.
Mitigation. When native vegetation meeting the mitigation size thresholds in Table 1 below has been approved for removal based on meeting one (1) or more of the above standards, the Vegetation Removal Permit shall only be used after an acceptable mitigation plan has been reviewed and approved by the Environmental Resources Director, or his/her designee. Prior to the issuance of any zoning compliance, certificate of capacity or other recognized authorization for the commencement of the permitted development activity, the replacement vegetation shall be preserved, relocated, or planted, or the appropriate mitigation fees shall be paid to the County. Only native vegetation shall be allowed to meet any required mitigation. The replacement vegetation shall be the same species as that which was removed, unless proven to be impractical, in which case, an alternative native species, approved by the Environmental Resources Director, or his/her designee, shall be used. The quality and size of the replacement trees shall meet the minimum landscape requirements set forth in Section 7.09.03(E). The Environmental Resources Director may authorize substitutions and phased or longer planting schedules that meet the environmental and aesthetic intent of the Land Development Code as long as the total diameter-at-breast-height requirement is still met, allowing trees to be mitigated with native shrubs and herbaceous plant materials at a ratio of one (1) inch to twenty-four (24) one-gallon plants. A waiver of all mitigation requirements shall require the approval of the Board of County Commissioners.
1.
Mitigation Sizes. Mitigation shall be required for the loss of any healthy, native vegetation with the minimum sizes as outlined in Table 1 below.
Vegetation shall be measured as "DBH", or diameter at breast height, which refers to trunk diameter at four and one-half (4½) feet above grade; or "C.T.", or clear trunk, which refers to the measurement of palm trees from grade to the base of the living fronds, or base of the head of palm trees. The three (3) multiple trunk species below, Seagrape, Pigeon Plum, and Wax Myrtle, shall qualify for mitigation when one (1) of their trunks meets the minimum size threshold listed below.
TABLE 1
2.
Mitigation Ratios.
a.
Calculating Required Mitigation.
1.
Where mitigation is required to compensate for the loss of native vegetation, meeting the minimum size thresholds outlined in Table 1, the replacement vegetation shall be calculated at a ratio of two (2) inches D.B.H. replacement per one inch D.B.H. removed (2:1). {For example, removal of a twelve-inch Slash Pine results in twenty-four (24) inches required mitigation}
2.
Palm tree mitigation shall be calculated at a ratio of one palm tree preserved/relocated/planted per one palm tree removed (1:1). Palm trees shall not be counted towards mitigation of non-palm species. {For example, removal of one (1) Cabbage Palm with a clear trunk measuring ten (10) feet or greater results in required mitigation of one (1) Cabbage Palm with a clear trunk measuring ten (10) feet or greater.}
b.
Calculating Mitigation Credit.
TABLE 2.a.
{For example, if a 6" Slash Pine is preserved on site, 12" of credit is granted; if a 6" Slash Pine is relocated, 9" of credit is granted; and if a 6" Slash Pine is planted on site, 6" of credit is granted.}
Table 2.b.
{For example, if a 10' Cabbage Palm is preserved on site a credit of one palm tree is granted; if a 10' Cabbage Palm is relocated on or off site, a credit of one palm tree is granted; and if a 10' Cabbage Palm is planted on site, a credit of one-half of a palm tree is granted.}
3.
Mitigation Compliance Methods.
a.
Diameter based mitigation methods shall be considered as follows:
1.
All native vegetation shall be protected on site to the greatest extent possible. If this is demonstrated to the satisfaction of the Public Works Director, or his/her designee, to be impractical, then;
2.
All native vegetation, that occurs in areas to be impacted by a proposed development activity requiring the removal of the vegetation, shall be relocated elsewhere on or off site, to the greatest extent possible. Vegetation relocated off-site shall be relocated to a publicly owned property within St. Lucie County, to a location approved by the County. A plan, outlining proposed transplant and maintenance methods, shall be approved by the Public Works Director pursuant to this option being permitted. In order to be credited towards mitigation for a site, the applicant must be responsible for all of the costs responsibilities of the relocation operation. If this is demonstrated to the satisfaction of the Public Works Director, or his/her designee, to be impractical, then;
3.
The amount of mitigation shall be planted on the development site using the following credit ratios.
Table 3
{For example, if a 12" tree is planted, then 24 inches of credit are granted.}
The replanting design shall allow for adequate root and crown development. If this is demonstrated to the satisfaction of the Public Works Director, or his/her designee, the development site does not have the capacity to hold all of the required mitigation, then;
4.
Contribute two hundred dollars ($200.00) per inch D.B.H. of remaining required mitigation to the County to be used at the County's discretion for either the acquisition and maintenance of publicly owned environmentally unique lands, or to be used for relocating or replanting native trees on public lands.
b.
Alternative Mitigation Compliance Methods. A complete Environmental Assessment shall be required for the following mitigation methods, therefore a tree survey shall not be required unless specifically requested by the Public Works Director, or his/her designee.
1.
If a site is consistent with the following minimum standards, twenty-five percent (25%) of the existing native upland habitat can be preserved on site to take the place of all tree mitigation requirements.
a.
The habitat preservation area shall not measure less than fifteen (15) percent of a total site, unless it is proven to the satisfaction to the Public Works Director, or his/her designee, that fifteen percent (15%) of the total site would prevent reasonable development of the site, then the preserve area may measure less than fifteen percent (15%) of the site, but shall measure no less than fifty (50) acres;
b.
The habitat preservation area shall be interconnected with adjacent habitat preserve areas in neighboring parcels where applicable, to facilitate appropriate management and to maximize natural resources values;
c.
Habitat preservation areas shall minimize edge to interior ratio, and shall have no minimum dimension less than one hundred (100) feet, and shall not exceed a length to width ratio of three to one (3:1) unless exceeding this ratio allows for superior connections with adjacent parcels or other environmental benefits.
d.
The habitat preservation area shall be platted in its entirety as separate tract or tracts.
e.
The habitat preservation area must be covered by a Conservation Easement dedicated to, or made in favor of, the County.
f.
The habitat preserve area shall have "Preserve Area Management and Monitoring Plan" approved by the County in order to ensure the continued, adequate, and appropriate management of the site and the continued protection of the site from adverse impacts. The Preserve Area Management Plan shall be recorded in the public records of the County and shall at a minimum identify the area covered by the plan, its ownership, and assignment of management and maintenance responsibility.
g.
If the preserve area is identified in either the St. Lucie County Native Habitat Inventory or the St. Lucie County Greenway's and Trails Master Plan, then all or portions of the above outlined guidelines may be waived with the approval of the County Commission.
h.
If the area proposed for preservation does not qualify as high quality native habitat, a restoration plan may be submitted including one hundred percent (100%) exotic removal, a planting plan incorporating canopy, sub-canopy, and ground cover species. Ninety percent (90%) survival rate will be required of the plant materials and shall be guaranteed as part of the "Preserve Area Management and Monitoring Plan".
2.
Purchase the required amount of remaining mitigation, using the credit ratio outlined in Table 3, and facilitate the installation, by a qualified professional, on an approved publicly managed site, including Environmental Significant Land properties, parks, road right-of-ways, or other public facility, or delivery to the St. Lucie County nursery program; or
3.
The purchase of land off the subject parcel, elsewhere in St. Lucie County on a property identified in either the St. Lucie County Native Habitat Inventory or the St. Lucie County Greenway's and Trails Master Plan, to be given to St. Lucie County for ownership and management. The off-site land shall be similar in ecological value based on habitat existing on site as well as the land value of the subject parcel.
4.
A property owner may propose to establish or acquire credits in an off-site mitigation bank located in St. Lucie County. A report, including the location of the property, an environmental assessment of the property, a tree survey (if applicable), a restoration plan (if applicable), and a management plan shall be submitted for this option to be considered. The mitigation bank property shall either be given to St. Lucie County for ownership and management or placed under a conservation easement, dedicated to, or in favor of, St. Lucie County.
4.
[Inspection required.] As part of the issuance of any Final Development Order/Permit requiring the mitigation of trees as set forth in this Code, the property owner shall submit to an inspection of the planted/relocated/preserved materials eighteen (18) months after the issuance of a certificate of occupancy or other use authorization as may be granted by the Public Works Director, or his/her designee for the County. If it is determined that the planted/relocated/preserved trees are dead, diseased or otherwise not in compliance with the provisions of this Code and the original approved mitigation plan, the property owner shall be provided notice and directed to correct any observed deficiencies and replace all noncompliant trees within sixty (60) days. Failure to maintain all required mitigation shall be grounds for referral to the Code Enforcement Board for appropriate enforcement actions. The Public Works Director, or his/her designee is authorized to include within the building permit fee, adequate charges to cover the costs of enforcing the requirements of this section.
E.
Supplemental Requirements. The Public Works Director, or his/her designee may impose supplemental requirements as a special condition of a Vegetation Removal Permit when necessary to carry out the intent of this Section. These supplemental standards shall be based upon the suggested standards in the latest edition of the "Tree Protection Manual for Builders and Developers" published by the Division of Forestry of the Florida Department of Agriculture and Consumer Services, or a similarly recognized reference manual.
(Ord. No. 12-003, Pt. C, 5-15-2012)
F.S. §§ 403.9321 through 403.9333, recognize the value that mangroves have on the natural function of the ecosystem throughout the State of Florida and the economic impact that a healthy mangrove system has on the sports and commercial fishing industries of the State. The Florida Department of Environmental Protection has been delegated by the Florida Legislature the statewide responsibility for the protection of the mangrove forest system, with specific allowances for limited trimming and alteration to be conducted by professional mangrove trimmers without the need for prior permit authorizations. Any person seeking to alter or trim mangroves in the unincorporated parts of St. Lucie County may do so only incompliance with the provisions of F.S. §§ 403.9321 through 403.9333, as may be amended from time to time. Any person seeking to alter or trim mangroves in the unincorporated parts of St. Lucie County must contact the Florida Department of Environmental Protection for permitting requirements.
Local delegation of mangrove regulation has not been requested by St. Lucie County.
A.
Purpose and Intent. The purpose of these regulations, recognizing the unique and environmentally sensitive characteristics of the coastal area, is to protect the economy and ecology of the coastal area by establishing policies and procedures for evaluating and minimizing the impacts of development within the coastal area and to provide controlled access to the shoreline.
The intent of these regulations is to assist in implementing Federal and State laws regarding coastal management, including the Federal Coastal Zone Management Act of 1972; F.S. Ch. 163, Part II, County and Municipal Planning and Land Development Regulation; and recommendations of the Hutchinson Island Resource Planning and Management Plan.
B.
Overall Review and Consistency.
1.
The regulations contained in this Section shall apply to all development within the unincorporated limits of North Hutchinson Island and South Hutchinson Island and to land within the Coastal High Hazard Area in the unincorporated area of St. Lucie County, which shall be considered the "V" zone according to the best available information from the Federal Emergency Management Administration.
2.
No development shall be approved unless consistent with the applicable policies set out in this Section. All development shall be reviewed by the Growth Management Director for consistency with the policies set out in this Section.
3.
All development not required to file for site plan approval under Section 11.02.00 of this Code shall provide the information necessary to evaluate conformance to this Section on forms provided by the Growth Management Director.
C.
Environmentally Sensitive Resources and Habitats. All development in the coastal area as defined in Section 6.02.01(B) is required to comply with the following criteria in order to protect environmentally sensitive resources and habitats:
1.
Alteration, Degradation or Destruction Criteria: No development shall be allowed that results in the alteration, degradation or destruction of environmentally sensitive resources or habitats, except when any of the following apply:
a.
The development is necessary to prevent or eliminate a public hazard.
In order for this exception to apply, all of the following must be found applicable:
(1)
A hazard or danger exists;
(2)
The development would eliminate or prevent the hazard;
(3)
The development would represent the best way to accomplish the desired end with minimal impact on the resources or habitats; and
(4)
Elimination of the hazard unavoidably impacts the resources or habitats.
b.
The development would provide direct public benefits which would exceed those lost to the public as a result of the resource or habitat alteration, degradation or destruction.
In order for this exception to apply, all of the following must be found applicable:
(1)
The development would meet a demonstrated public need;
(2)
The development would provide public benefits more valuable than those already provided by the resource or habitat prior to development;
(3)
The development would cause a minimal loss of resource or habitat function consistent with meeting the need; and
(4)
The development would represent the best method of satisfying the identified need.
c.
The development is proposed for environmentally sensitive habitats in which the functions and values currently provided are significantly less than those typically associated with such habitat types.
In order for this exception to apply, all of the following must be found applicable:
(1)
The functions and values provided by the habitat are significantly reduced below those typically associated with that habitat type;
(2)
The benefits currently provided are minimal and of little ecological consequence;
(3)
The reduction in value is irreversible and cannot practically be restored by the landowner, persons undertaking development, or governmental agencies; and
(4)
The development would be carried out in a manner least damaging to the habitat.
d.
The development is water dependent or, due to the unique configuration of the site, minimal impact is the unavoidable consequence of development for uses which are appropriate given general site characteristics; however, in no case shall such development be allowed for the purpose of obtaining fill.
In order for this exception to apply, all of the following must be found applicable:
(1)
The development is necessary in order to develop usable portions of the site;
(2)
The proposed use is appropriate and reasonable given site characteristics or is water dependent; and
(3)
The design and layout of the proposed development is the least disruptive to the environmentally sensitive resources or habitats.
2.
Groundwater and Surface Water: All development shall comply with the following criteria in order to facilitate the recharging of groundwater and protect the quality of groundwater and surface water resources:
a.
Impervious surfaces shall be held to a minimum and porous materials shall be substituted to the maximum extent feasible.
b.
Site design shall maximize use of onsite water recharge capability.
c.
Surface water management measures shall be designed to minimize changes in the pre-development quantity, quality, rate and temporary characteristics of stormwater discharge.
d.
Surface water management measures shall result in no degradation of surface water draining into environ-mentally sensitive resources and habitats.
3.
Protected Species: All development shall comply with the following criteria concerning federal and state protected species, as defined in Chapter II, and their habitats:
a.
Pre-development: If it is determined that a federal or state protected species is resident on or otherwise is significantly dependent upon the subject parcel of land, the person undertaking development shall consult with the Florida Game and Fresh Water Fish Commission, U.S. Fish and Wildlife Service, and the County. Appropriate protection to the satisfaction of all parties shall be provided prior to approval of the development. When off-site mitigation or relocation of federal or state protected species is required, these activities shall be required to take place within St. Lucie County unless the appropriate federal or state regulatory agency finds that no suitable habitat located in the County is available to accept additional relocated species.
b.
Notification Requirement: In the event that it is determined that any representative of a federal or state protected species is resident on or otherwise is significantly dependent upon the subject parcel of land for which development is underway, the person undertaking development shall be required to cease all development work which might adversely affect that individual species or population and immediately notify the Florida Game and Fresh Water Fish Commission, U.S. Fish and Wildlife Service, and the County. Appropriate protection to the satisfaction of all parties shall be provided by the person undertaking development prior to resuming development.
4.
[Permit required.] A permit from the Florida Department of Environmental Protection must be obtained for all construction seaward of the adopted Coastal Construction Control Line. This includes all buildings, garages, and accessory structures, including but not limited to, pools, sun decks, boardwalks, tennis courts, and paved areas for parking.
D.
Vegetation and Landscaping. All development is required to comply with the following criteria concerning the preservation of existing native vegetation, the use of native and non-native vegetation in landscaping, and the removal of exotic vegetation:
1.
Selective Clearing and Micro-Siting: All development requiring a County permit shall set aside through selective clearing and micro-siting of buildings, as a minimum, twenty-five percent (25%) of each native plant community which occurs onsite, such as, upland scrubland, upland mixed hammock, and duneland communities.
2.
Minimum Disturbance: Existing native vegetation shall be disturbed to the least degree practical.
3.
Landscape Criteria for Native or Drought Tolerant Vegetation: Landward of the frontal due one hundred percent (100%) of all landscaped areas, required pursuant to Section 7.09.00, shall be composed of native or drought tolerant vegetation adapted to soil and climatic conditions occurring onsite. It is recommended that compliance with these requirements is achieved through preservation of existing native vegetation.
E.

No Alternative Site: Restoration or creation may be permitted to compensate for wetland loss where an applicant demonstrates that the proposed activity cannot be practicably located on the upland portion of this site or another site.
b.
All Practical Measures will be taken to Reduce Impact: Restoration or creation may be permitted to compensate for wetland loss only where the applicant has modified the proposed development to reduce wetland loss and degradation. Acceptable modifications include site design to reduce fill into or drainage of the wetland; other erosion control measures where the activity will cause erosion; construction of pretreatment facilities for stormwater to be discharged into wetlands; and, scheduling restoration activities at such time of year as would have the least impact upon the wetland or endangered or threatened species.
3.
Mitigation for Loss of Small Wetlands. A developer may propose off-site mitigation for loss of wetlands of less than two (2) contiguous acres, but more than one-half-acre and otherwise subject to the regulations under Section 6.02.03.
4.
Standards for Mitigation.
a.
No Overall Net Losses: Restoration or creation of wetlands shall be permitted to compensate for wetland losses only where restoration and/or creation will restore lost wetland functions and values. The following mitigation ratios shall be presumed to provide wetland functions and values if new wetlands are being created:
(1)
Tidal wetlands 2.0:1;
(2)
Freshwater forested swamp, non-cypress dominated 2.5:1;
(3)
Freshwater forested swamp, cypress dominated 2.0:1;
(4)
Freshwater marshes 1.5:1.
If the proposed wetland creation depends extensively on natural recolonization the ratio may be 3.0:1 to 4.0:1. Only where the created wetland can be expected to surpass the values and functions of the existing wetland can the ratio be adjusted downward.
The Growth Management Director shall require a ratio for restored or created functions and/or acreage exceeding the above ratios where:
(1)
Uncertainties exist as to the probable success of the proposed restoration or creation of wetlands; or,
(2)
The degradation or destruction of wetlands will deprive St. Lucie County of various wetland values for a period of time until the restoration or creation is completed and functional; or,
(3)
Mitigation is proposed offsite or not in kind; or,
(4)
Mitigation proposed includes restoration or enhancement of existing wetlands rather than creation of new wetlands.
b.
Adequate Hydrology, Soils and Other Basic Requirements: Wetland restoration, enhancement, or creation shall be permitted only where those hydrologic, soil, side slope, and other basic characteristics of the proposed project are adequate to achieve the proposed project goals.
c.
Function: Wetland restoration or creation shall be permitted to compensate for new wetland losses only where the restored or created wetland will be at least as functional as the existing wetland system it is intended to replace.
d.
Sufficient Financial Resources: Guarantees and sureties for approved mitigation shall be provided in accordance with Section 11.04.00.
e.
Maintenance and Monitoring: For all mitigation projects, the Growth Management Director shall require, at a minimum:
(1)
Maintenance of at least ninety percent (90%) survivorship of all plantings for at least two (2) years; and,
(2)
Annual monitoring reports of the status of the mitigation area, including number of surviving plantings and any plantings made to maintain ninety percent (90%) survivorship; and,
(3)
Annual replantings to maintain ninety percent (90%) survivorship; and,
(4)
Removal of exotic vegetation, as appropriate.
F.
Required Buffering. A buffer zone of native upland edge (i.e., transitional) vegetation shall be provided and maintained around isolated wetlands covered by this Section which are constructed or preserved on new development sites. The buffer zone may consist of preserved or planted vegetation but shall include canopy, understory, and ground cover of native species only. The edge habitat shall begin at the upland limit of any wetland or deepwater habitat. As a minimum, ten (10) square feet of such buffer shall be provided for each linear foot of wetland or deepwater habitat perimeter that lies adjacent to uplands. This upland edge habitat shall be located such that no less than fifty percent (50%) of the total shoreline is buffered by a minimum width of ten (10) feet of upland habitat. The upland buffer requirement does not apply to drainage canals or stormwater conveyance systems requiring periodic maintenance.

RESOURCE PROTECTION STANDARDS
Editor's note—Ord. No. 18-001, Pt. A adopted January 23, 2018, repealed the former 6.05.00, §§ 6.05.01—6.05.07, and enacted a 6.05.00 as set out herein. The former 6.05.00 pertained to flood damage prevention and derived from Ord. No. 11-031, adopted December 2, 2011 and Ord. No. 12-010, adopted February 14, 2012.
It is the intent of the Board of County Commissioners to provide for the health, safety, and welfare of the residents of and visitors to St. Lucie County by establishing an administrative review process which encourages preservation of native habitat, and long-term sustainability of our urban forest in accordance with the St. Lucie County Comprehensive Plan and beneficial land and forest management practices by minimizing the unnecessary removal of valuable existing vegetation in advance of approved land development within the unincorporated area of St. Lucie County. Healthy vegetation reduces air and noise pollution, provides for the production of oxygen and sequestering of carbon dioxide, provides energy-saving shade and cooling, furnishes habitat for wildlife, enhances aesthetics and property values, and is an important contributor to community image, pride, and quality of life. In addition, it is the intent of the Board to prevent such destructive land development practices as speculative vegetation removal and clear cutting of land without a site plan or vegetation management and mitigation plan.
A.
The provisions of the following Sections shall supersede the provisions of this Section to the extent of conflict.
1.
Mangrove Protection, Section 6.01.00;
2.
Environmentally Sensitive Lands, Section 6.02.00;
3.
Wetland Protection, Section 6.02.03;
4.
Coastal Area Protection, Section 6.02.01;
5.
Shoreline Protection, Section 6.02.02;
6.
Habitat of Endangered and Threatened Species, Section 6.03.00;
A.
No person shall conduct any vegetation removal activities from or on any lot or parcel of land or portion thereof in the unincorporated area of St. Lucie County without first obtaining a Notice of Vegetation Removal from the Public Works Director, or his/her designee. The Notice of Vegetation Removal application shall be completed in conformance with Section 11.05.06 of this Code. Protected vegetation shall be defined as native vegetation. Types of Notice of Vegetation Removal approval include:
1.
Exemptions. A number of specific activities have been determined to have minimal adverse impact and are listed in Section 6.00.04.
2.
Vegetation Removal Permit. A Vegetation Removal Permit shall be issued if all the criteria set forth in 6.00.05 has been met.
B.
Unless otherwise provided in this Code, all public entities, including all departments of St. Lucie County government, shall be subject to the requirements of this Section. Public entities, however, shall not be subject to:
1.
The application fees under Section 11.12.00 of this Code; or
2.
The penalties under by Section 11.13.03 of this Code.
C.
The provisions of this Section may be suspended or waived by the Public Works Director, or his/her designee during a period of emergency officially declared by the Board of County Commissioners.
D.
The following activities shall require no official notification to the Public Works Director, or his/her designee:
1.
Preserve and Parks Management Activities. Vegetation removal activities associated with an adopted management plan for government maintained parks, recreation areas, wildlife management areas, conservation areas and preserves. The purpose of the vegetation removal activity shall be to protect and preserve the natural values and functions of the ecological communities present, such as, clearing for firebreaks, conducting prescribed burns, or construction of fences.
2.
Existing Agricultural Operations. Vegetation removal, except within required preserve areas or deeded conservation easements, which are part of the on-going activities of the existing agricultural operation, shall not require a permit. Initial clearing of native vegetation on a site shall be preceded by a letter to the Environmental Resources Division. Bona fide agricultural activities include commercial nursery, citrus groves, tree farm, aquaculture, row crops, ranch, or similar operation. When removal of protected vegetation, has been performed under this exemption no development order shall be approved for any other use or improvement, including subdividing, on the same land within four (4) years from the date of the last agricultural classification granted for that land by the St. Lucie County Property Appraiser per F.S. § 193.461. In the event of a hardship such as a natural disaster, the owner may request that the Board of County Commissioners grant a variance from the provisions of this subsection. The Board shall only grant the variance if the Board determines that the owner has presented evidence that the owner has satisfied the standards of Section 10.01.02 of the Land Development Code.
3.
Routine Landscape Maintenance. Trimming or pruning of vegetation which is not intended to result in the eventual death of the vegetation, mowing of yards or lawns, or any other landscaping or gardening activity which is commonly recognized as routine maintenance, replacement or relandscaping which does not result in the eventual death of any vegetation, does not require the approval of a Notice of Vegetation Removal.
Any person who intends to remove or cause the death of any vegetation pursuant to any of the following exemptions must first obtain a Notice of Vegetation Removal from the Public Works Director, or his/her designee or his/her designee. The burden of proving entitlement to any particular exemption shall lie, at all times, with the person or persons claiming the exemption.
A.
The removal of any native vegetation as necessary for the following activities:
1.
The minimal removal of native vegetation necessary for a path not to exceed four (4) feet in width to provide physical access or view necessary to conduct a survey or site examination for the preparation of bona fide site development plans or vegetation inventories; or
2.
The minimal removal of native vegetation necessary for a path not to exceed ten (10) feet in width to provide vehicular access necessary to conduct soil percolation or soil bore tests, provided such clearing or removal is conducted under the direction of Florida registered surveyor or engineer.
B.
The removal of any native vegetation in an existing utility easement, drainage easement, storm water management tract or facility, or right-of-way provided such work is done by or under the control of the operating unit of local, state, or federal government, utility company and that unit of local, state, or federal government or utility company has obtained all necessary licenses or permits to provide service through the easement.
C.
The removal of native vegetation which has been determined to be a safety hazard, destroyed or damaged beyond saving by natural causes or causes not covered by other sections of this chapter, is infected with disease or is infested with insects, or which constitutes immediate peril to life property or other trees, and where pruning or trimming of the vegetation is not able to alleviate the hazard.
D.
The removal of native vegetation, upon any detached single family residential lot or parcel of land having an area of one (1) acre or less. This exemption is, however, subject to the following conditions:
1.
Nothing in this exemption shall exempt any person from the landscaping requirements set forth in Section 7.09.00 of this Code;
2.
This exemption shall not be construed to allow the removal or alteration of any protected vegetation without a Vegetation Removal Permit on any exempted lot or parcel of land by its subdivider unless the subdivider intends in good faith to construct a residential unit or units upon the lot or parcel of land prior to its sale. Advertisement or listing the lot or parcel of land for sale without a residential unit shall create a presumption that the subdivider does not intend to construct such a unit and that the intent is for a subsequent purchaser to develop the lot or parcel.
3.
No native vegetation twenty-four (24) inches, or greater, dbh shall be removed from any residential parcel (including those in the AG-5, AG-2.5, AG-1, AR-1, RE-1, and R/C zoning districts), regardless of parcel size, without an approved Vegetation Removal Permit and an approved mitigation plan. The Public Works Director, or his/her designee may reduce the requirements for mitigation on individual residential lots one-half-acre or less where a protected tree twenty-four (24) inches dbh or greater must be removed in order to provide for the reasonable use of the property.
E.
The removal or alteration of any non-native vegetation.
A.
Removal of Native Vegetation. The Public Works Director, or his/her designee, shall issue a Vegetation Removal Permit only if a completed application has been submitted to the Public Works Director, or his/her designee, and is accompanied by sufficient evidence demonstrating that at least one (1) of the following criteria has been satisfied:
1.
The applicant for a final development order shall demonstrate that the removal of the native vegetation is the minimum necessary in order to implement a Final Development Order and that reasonable efforts have been made to microsite impervious surfaces to protect native vegetation or provide details supporting why preservation of the existing native vegetation is not practically feasible and prevents the reasonable development of the site. The Public Works Director, or his/her designee shall determine the appropriateness of any such claim. The applicant shall provide the Public Works Director, or his/her designee, or his/her designee, a survey of the property outlining the areas of proposed vegetation removal including the location of all vegetation as outlined in Section 11.05.06.
2.
A Final Development Order has not been issued, or is not required by this Code. The applicant for the vegetation removal permit shall demonstrate that the removal of the native vegetation is the minimum necessary in order to allow for the construction of the intended use or improvement of the property and that reasonable efforts have been made to microsite impervious surfaces to protect native vegetation or provide details supporting why preservation of the existing native vegetation is not practically feasible and prevents the reasonable development of the site. The Public Works Director, or his/her designee shall determine the appropriateness of any such claim. The applicant shall provide the Public Works Director, or his/her designee, or his/her designee, a survey of the property outlining the areas of proposed vegetation removal including the location of all vegetation as outlined in Section 11.05.06.
B.
Limiting Removal of Native Vegetation. Prior to the removal of any native vegetation, the removal plan must demonstrate that effective efforts have been made to micro-site impervious surfaces to avoid or minimize impacts to such vegetation.
The extent of approval to remove any native vegetation shall be limited by the Public Works Director, or his/her designee to the minimum necessary to accomplish the purpose of the removal. This may include limiting the extent of approval to portions of a lot or parcel of land or specifying special conditions by which removal shall take place. Such limitation shall be clearly indicated in writing on or attached to the Vegetation Removal Permit. If vegetation removal is limited to a portion of a lot or parcel of land, the extent of such limitation shall be clearly delineated on the face of any site development plans. The application for Vegetation Removal Permit shall demonstrate consistency with the requirements of Section 7.09.03(E)(7).
C.
Vegetation Protection Standards During the Duration of an Approved Notice of Vegetation Removal. The following minimum standards for vegetation protection shall be applied to any area of vegetation designated to be preserved under the terms of an approved Vegetation Removal:
1.
A conspicuous, suitable protective barrier, constructed of metal, wood, safety fencing or other durable material, shall be placed and maintained around the perimeter of the protected area to form a continuous unbroken boundary, around individual protected trees, or groups of protected vegetation, or other protected areas, as follows:
a.
At a minimum distance of twenty-five (25) feet from all jurisdictional wetlands; or
b.
At a minimum distance of ten (10) feet from all required shoreline buffer zones as required in Sections 6.02.01 and 6.02.02.
c.
At a minimum distance of either ten (10) feet from the edge of groups or areas of protected vegetation or from the radius of the dripline from all protected trees, whichever is greater; or
d.
As otherwise provided in special conditions attached to a Notice of Vegetation Removal.
2.
Special care shall be taken that preservation areas are properly marked and highly visible so that equipment operators can see the limits of permitted removal activity.
3.
Protective barriers or protective designations shall remain in place until removal is authorized by the Public Works Director, or his/her designee, or until issuance of a certificate of occupancy or other use authorization as may be granted by the Public Works Director, or his/her designee.
In the event that any protective barriers are removed or altered and clearing activities are conducted within an area identified for preserve under the issued Vegetation Removal Permit, the Public Works Director, or his/her designee is authorized to direct that all land clearing and site alteration work at the site be stopped until the barriers are restored and any necessary corrective actions taken to repair or replant any vegetation removed or damaged as a result of these encroachments.
4.
The entire vegetation preservation area shall be maintained in its natural state so as not to alter the water and oxygen content of the soil and impair its natural function.
5.
No grade changes or excavation of any sort may be made within the vegetation preservation area that require trenching or cutting of roots, except in compliance with the terms of special conditions in an approved Vegetation Removal Permit. If underground utilities must be routed through a protected root zone area, tunneling under the roots shall be required. Irrigation shall be installed outside of the dripline of all protected trees.
These modifications shall be based upon the suggested standards in the latest edition of the "Tree Protection Manual for Builders and Developers" published by the Division of Forestry of the Florida Department of Agriculture and Consumer Services, or a similarly recognized reference manual.
6.
No soil shall be removed from within a vegetation preservation area.
7.
No fill material, construction material, concrete, paint, chemicals, or other foreign materials shall be stored, deposited or disposed of within a vegetation preservation area.
8.
No signs, permits, wires, or other attachments, other than those of protective and non-damaging nature, shall be affixed or attached to protected vegetation.
9.
If landscaping is to be installed within a vegetation preservation area after removal of protective barriers or designations, installation shall be accomplished using hand labor, unless use of light machinery is proven to be necessary and methodology is approved by the Public Works Director, or his/her designee.
10.
Any equipment, including passenger vehicles, shall not be driven, parked, or stored or repaired within designated vegetation preservation areas.
11.
Vegetation destroyed or damaged as part of the development of a site or parcel, shall be replaced by vegetation of equal environmental value as specified by the Public Works Director, or his/her designee, in consultation with the Growth Management Director, before any occupancy or final use permit authorizations are issued.
12.
The authorized removal of any non-protected vegetation in the vegetation preservation area shall be accomplished using hand labor, unless use of light machinery is proven to be necessary and methodology is approved by the Public Works Director, or his/her designee. Only the above ground portions of the non-protected vegetation may be removed and the stump shall be properly treated with an approved herbicide; the root systems of the protected vegetation must remain undisturbed.
13.
If any roots of protected vegetation is exposed or damaged, the applicant shall immediately correct the situation by covering the roots with a high quality of soil to match the existing grades, pruning any splintered roots and providing water until the vegetation has recovered.
14.
The applicant shall provide the Public Works Director, or his/her designee, a written plan to control erosion which may be expected to occur as a result of the proposed removal of protected vegetation. The erosion control plan must be approved by the Public Works Director, or his/her designee, prior to the commencement of any removal of protected vegetation. All provisions of the plan shall be incorporated as express conditions of any Notice of Vegetation Removal issued under this paragraph.
D.
Mitigation. When native vegetation meeting the mitigation size thresholds in Table 1 below has been approved for removal based on meeting one (1) or more of the above standards, the Vegetation Removal Permit shall only be used after an acceptable mitigation plan has been reviewed and approved by the Environmental Resources Director, or his/her designee. Prior to the issuance of any zoning compliance, certificate of capacity or other recognized authorization for the commencement of the permitted development activity, the replacement vegetation shall be preserved, relocated, or planted, or the appropriate mitigation fees shall be paid to the County. Only native vegetation shall be allowed to meet any required mitigation. The replacement vegetation shall be the same species as that which was removed, unless proven to be impractical, in which case, an alternative native species, approved by the Environmental Resources Director, or his/her designee, shall be used. The quality and size of the replacement trees shall meet the minimum landscape requirements set forth in Section 7.09.03(E). The Environmental Resources Director may authorize substitutions and phased or longer planting schedules that meet the environmental and aesthetic intent of the Land Development Code as long as the total diameter-at-breast-height requirement is still met, allowing trees to be mitigated with native shrubs and herbaceous plant materials at a ratio of one (1) inch to twenty-four (24) one-gallon plants. A waiver of all mitigation requirements shall require the approval of the Board of County Commissioners.
1.
Mitigation Sizes. Mitigation shall be required for the loss of any healthy, native vegetation with the minimum sizes as outlined in Table 1 below.
Vegetation shall be measured as "DBH", or diameter at breast height, which refers to trunk diameter at four and one-half (4½) feet above grade; or "C.T.", or clear trunk, which refers to the measurement of palm trees from grade to the base of the living fronds, or base of the head of palm trees. The three (3) multiple trunk species below, Seagrape, Pigeon Plum, and Wax Myrtle, shall qualify for mitigation when one (1) of their trunks meets the minimum size threshold listed below.
TABLE 1
2.
Mitigation Ratios.
a.
Calculating Required Mitigation.
1.
Where mitigation is required to compensate for the loss of native vegetation, meeting the minimum size thresholds outlined in Table 1, the replacement vegetation shall be calculated at a ratio of two (2) inches D.B.H. replacement per one inch D.B.H. removed (2:1). {For example, removal of a twelve-inch Slash Pine results in twenty-four (24) inches required mitigation}
2.
Palm tree mitigation shall be calculated at a ratio of one palm tree preserved/relocated/planted per one palm tree removed (1:1). Palm trees shall not be counted towards mitigation of non-palm species. {For example, removal of one (1) Cabbage Palm with a clear trunk measuring ten (10) feet or greater results in required mitigation of one (1) Cabbage Palm with a clear trunk measuring ten (10) feet or greater.}
b.
Calculating Mitigation Credit.
TABLE 2.a.
{For example, if a 6" Slash Pine is preserved on site, 12" of credit is granted; if a 6" Slash Pine is relocated, 9" of credit is granted; and if a 6" Slash Pine is planted on site, 6" of credit is granted.}
Table 2.b.
{For example, if a 10' Cabbage Palm is preserved on site a credit of one palm tree is granted; if a 10' Cabbage Palm is relocated on or off site, a credit of one palm tree is granted; and if a 10' Cabbage Palm is planted on site, a credit of one-half of a palm tree is granted.}
3.
Mitigation Compliance Methods.
a.
Diameter based mitigation methods shall be considered as follows:
1.
All native vegetation shall be protected on site to the greatest extent possible. If this is demonstrated to the satisfaction of the Public Works Director, or his/her designee, to be impractical, then;
2.
All native vegetation, that occurs in areas to be impacted by a proposed development activity requiring the removal of the vegetation, shall be relocated elsewhere on or off site, to the greatest extent possible. Vegetation relocated off-site shall be relocated to a publicly owned property within St. Lucie County, to a location approved by the County. A plan, outlining proposed transplant and maintenance methods, shall be approved by the Public Works Director pursuant to this option being permitted. In order to be credited towards mitigation for a site, the applicant must be responsible for all of the costs responsibilities of the relocation operation. If this is demonstrated to the satisfaction of the Public Works Director, or his/her designee, to be impractical, then;
3.
The amount of mitigation shall be planted on the development site using the following credit ratios.
Table 3
{For example, if a 12" tree is planted, then 24 inches of credit are granted.}
The replanting design shall allow for adequate root and crown development. If this is demonstrated to the satisfaction of the Public Works Director, or his/her designee, the development site does not have the capacity to hold all of the required mitigation, then;
4.
Contribute two hundred dollars ($200.00) per inch D.B.H. of remaining required mitigation to the County to be used at the County's discretion for either the acquisition and maintenance of publicly owned environmentally unique lands, or to be used for relocating or replanting native trees on public lands.
b.
Alternative Mitigation Compliance Methods. A complete Environmental Assessment shall be required for the following mitigation methods, therefore a tree survey shall not be required unless specifically requested by the Public Works Director, or his/her designee.
1.
If a site is consistent with the following minimum standards, twenty-five percent (25%) of the existing native upland habitat can be preserved on site to take the place of all tree mitigation requirements.
a.
The habitat preservation area shall not measure less than fifteen (15) percent of a total site, unless it is proven to the satisfaction to the Public Works Director, or his/her designee, that fifteen percent (15%) of the total site would prevent reasonable development of the site, then the preserve area may measure less than fifteen percent (15%) of the site, but shall measure no less than fifty (50) acres;
b.
The habitat preservation area shall be interconnected with adjacent habitat preserve areas in neighboring parcels where applicable, to facilitate appropriate management and to maximize natural resources values;
c.
Habitat preservation areas shall minimize edge to interior ratio, and shall have no minimum dimension less than one hundred (100) feet, and shall not exceed a length to width ratio of three to one (3:1) unless exceeding this ratio allows for superior connections with adjacent parcels or other environmental benefits.
d.
The habitat preservation area shall be platted in its entirety as separate tract or tracts.
e.
The habitat preservation area must be covered by a Conservation Easement dedicated to, or made in favor of, the County.
f.
The habitat preserve area shall have "Preserve Area Management and Monitoring Plan" approved by the County in order to ensure the continued, adequate, and appropriate management of the site and the continued protection of the site from adverse impacts. The Preserve Area Management Plan shall be recorded in the public records of the County and shall at a minimum identify the area covered by the plan, its ownership, and assignment of management and maintenance responsibility.
g.
If the preserve area is identified in either the St. Lucie County Native Habitat Inventory or the St. Lucie County Greenway's and Trails Master Plan, then all or portions of the above outlined guidelines may be waived with the approval of the County Commission.
h.
If the area proposed for preservation does not qualify as high quality native habitat, a restoration plan may be submitted including one hundred percent (100%) exotic removal, a planting plan incorporating canopy, sub-canopy, and ground cover species. Ninety percent (90%) survival rate will be required of the plant materials and shall be guaranteed as part of the "Preserve Area Management and Monitoring Plan".
2.
Purchase the required amount of remaining mitigation, using the credit ratio outlined in Table 3, and facilitate the installation, by a qualified professional, on an approved publicly managed site, including Environmental Significant Land properties, parks, road right-of-ways, or other public facility, or delivery to the St. Lucie County nursery program; or
3.
The purchase of land off the subject parcel, elsewhere in St. Lucie County on a property identified in either the St. Lucie County Native Habitat Inventory or the St. Lucie County Greenway's and Trails Master Plan, to be given to St. Lucie County for ownership and management. The off-site land shall be similar in ecological value based on habitat existing on site as well as the land value of the subject parcel.
4.
A property owner may propose to establish or acquire credits in an off-site mitigation bank located in St. Lucie County. A report, including the location of the property, an environmental assessment of the property, a tree survey (if applicable), a restoration plan (if applicable), and a management plan shall be submitted for this option to be considered. The mitigation bank property shall either be given to St. Lucie County for ownership and management or placed under a conservation easement, dedicated to, or in favor of, St. Lucie County.
4.
[Inspection required.] As part of the issuance of any Final Development Order/Permit requiring the mitigation of trees as set forth in this Code, the property owner shall submit to an inspection of the planted/relocated/preserved materials eighteen (18) months after the issuance of a certificate of occupancy or other use authorization as may be granted by the Public Works Director, or his/her designee for the County. If it is determined that the planted/relocated/preserved trees are dead, diseased or otherwise not in compliance with the provisions of this Code and the original approved mitigation plan, the property owner shall be provided notice and directed to correct any observed deficiencies and replace all noncompliant trees within sixty (60) days. Failure to maintain all required mitigation shall be grounds for referral to the Code Enforcement Board for appropriate enforcement actions. The Public Works Director, or his/her designee is authorized to include within the building permit fee, adequate charges to cover the costs of enforcing the requirements of this section.
E.
Supplemental Requirements. The Public Works Director, or his/her designee may impose supplemental requirements as a special condition of a Vegetation Removal Permit when necessary to carry out the intent of this Section.

F.S. §§ 403.9321 through 403.9333, recognize the value that mangroves have on the natural function of the ecosystem throughout the State of Florida and the economic impact that a healthy mangrove system has on the sports and commercial fishing industries of the State. The Florida Department of Environmental Protection has been delegated by the Florida Legislature the statewide responsibility for the protection of the mangrove forest system, with specific allowances for limited trimming and alteration to be conducted by professional mangrove trimmers without the need for prior permit authorizations. Any person seeking to alter or trim mangroves in the unincorporated parts of St. Lucie County may do so only incompliance with the provisions of F.S. §§ 403.9321 through 403.9333, as may be amended from time to time. Any person seeking to alter or trim mangroves in the unincorporated parts of St. Lucie County must contact the Florida Department of Environmental Protection for permitting requirements.
Local delegation of mangrove regulation has not been requested by St. Lucie County.
A.
Purpose and Intent. The purpose of these regulations, recognizing the unique and environmentally sensitive characteristics of the coastal area, is to protect the economy and ecology of the coastal area by establishing policies and procedures for evaluating and minimizing the impacts of development within the coastal area and to provide controlled access to the shoreline.
The intent of these regulations is to assist in implementing Federal and State laws regarding coastal management, including the Federal Coastal Zone Management Act of 1972; F.S. Ch. 163, Part II, County and Municipal Planning and Land Development Regulation; and recommendations of the Hutchinson Island Resource Planning and Management Plan.

In order for this exception to apply, all of the following must be found applicable:
(1)
A hazard or danger exists;
(2)
The development would eliminate or prevent the hazard;
(3)
The development would represent the best way to accomplish the desired end with minimal impact on the resources or habitats; and
(4)
Elimination of the hazard unavoidably impacts the resources or habitats.

The development would provide direct public benefits which would exceed those lost to the public as a result of the resource or habitat alteration, degradation or destruction.
In order for this exception to apply, all of the following must be found applicable:
(1)
The development would meet a demonstrated public need;
(2)
The development would provide public benefits more valuable than those already provided by the resource or habitat prior to development;
(3)
The development would cause a minimal loss of resource or habitat function consistent with meeting the need; and
(4)
The development would represent the best method of satisfying the identified need.
c.
The development is proposed for environmentally sensitive habitats in which the functions and values currently provided are significantly less than those typically associated with such habitat types.
In order for this exception to apply, all of the following must be found applicable:

In coastal high hazard areas, concrete slabs used as parking pads, enclosure floors, landings, decks, walkways, patios and similar nonstructural uses are permitted beneath or adjacent to buildings and structures provided the concrete slabs are designed and constructed to be:
(a)
Structurally independent of the foundation system of the building or structure;
(b)
Frangible and not reinforced, so as to minimize debris during flooding that is capable of causing significant damage to any structure; and
(c)
Have a maximum slab thickness of not more than four (4) inches.
6.
Decks and Patios in Coastal High Hazard Areas (Zone V). In addition to the requirements of the Florida Building Code, in coastal high hazard areas decks and patios shall be located, designed, and constructed in compliance with the following:
(a)
A deck that is structurally attached to a building or structure shall have the bottom of the lowest horizontal structural member at or above the design flood elevation and any supporting members that extend below the design flood elevation shall comply with the foundation requirements that apply to the building or structure, which shall be designed to accommodate any increased loads resulting from the attached deck.
(b)
A deck or patio that is located below the design flood elevation shall be structurally independent from buildings or structures and their foundation systems, and shall be designed and constructed either to remain intact and in place during design flood conditions or to break apart into small pieces to minimize debris during flooding that is capable of causing structural damage to the building or structure or to adjacent buildings and structures.
(c)
A deck or patio that has a vertical thickness of more than twelve (12) inches or that is constructed with more than the minimum amount of fill necessary for site drainage shall not be approved unless an analysis prepared by a qualified registered design professional demonstrates no harmful diversion of floodwaters or wave runup and wave reflection that would increase damage to the building or structure or to adjacent buildings and structures.
(d)
A deck or patio that has a vertical thickness of twelve (12) inches or less and that is at natural grade or on nonstructural fill material that is similar to and compatible with local soils and is the minimum amount necessary for site drainage may be approved without requiring analysis of the impact on diversion of floodwaters or wave runup and wave reflection.
7.
Other Development in Coastal High Hazard Areas (Zone V). In coastal high hazard areas, development activities other than buildings and structures shall be permitted only if also authorized by the appropriate federal, state or local authority; if located outside the footprint of, and not structurally attached to, buildings and structures; and if analyses prepared by qualified registered design professionals demonstrate no harmful diversion of floodwaters or wave runup and wave reflection that would increase damage to adjacent buildings and structures. Such other development activities include but are not limited to:
(a)
Bulkheads, seawalls, retaining walls, revetments, and similar erosion control structures;
(b)
Solid fences and privacy walls, and fences prone to trapping debris, unless designed and constructed to fail under flood conditions less than the design flood or otherwise function to avoid obstruction of floodwaters; and

8.
Nonstructural Fill in Coastal High Hazard Areas (Zone V). In coastal high hazard areas:
(a)
Minor grading and the placement of minor quantities of nonstructural fill shall be permitted for landscaping and for drainage purposes under and around buildings provided the fill will wash out from storm surge, thereby rendering the building free of obstruction prior to generating excessive loading forces, ramping effects, or wave deflection.
(b)
Nonstructural fill with finished slopes that are steeper than one (1) unit vertical to five (5) units horizontal shall be permitted only if an analysis prepared by a qualified registered design professional demonstrates no harmful diversion of floodwaters or wave runup and wave reflection that would increase damage to adjacent buildings and structures, and that the volume and distribution of fill will not cause wave deflection on adjacent buildings and structures.
(c)
Where authorized by the Florida Department of Environmental Protection or applicable local approval, sand dune construction and restoration of sand dunes under or around elevated buildings are permitted without additional engineering analysis or certification of the diversion of floodwater or wave runup and wave reflection if the scale and location of the dune work is consistent with local beach-dune morphology and the vertical clearance is maintained between the top of the sand dune and the lowest horizontal structural member of the building.
