§ 3.05.07. Preservation Standards
All development not specifically exempted by this ordinance shall incorporate, at a minimum, the preservation standards contained within this section.
A.
General standards and criteria. The following criteria shall be used to administer the preservation standards in all unincorporated areas of the County:
1.
Native vegetative communities. The preservation of native vegetation shall include all naturally occurring strata including canopy, understory and ground cover emphasizing the largest contiguous area possible, except as otherwise provided in section 3.05.07 H.1.e. The term native vegetation is further defined as a vegetative community having 25 percent or more canopy coverage or highest existing vegetative strata of native plant species. In the absence of other native strata, herbaceous vegetation not typically associated with the re-growth of native vegetative communities, commonly known as weeds, shall not be considered native vegetation for the purpose of preservation.
2.
Native trees. Where a property has been legally cleared and only native trees remain and the native ground cover replaced with lawn or pasture, then only the native trees shall be retained. The percent requirement of native trees required to be retained shall be by tree count based on the percent requirement for native vegetation pursuant to 3.05.07 B. Only slash pine trees with an 8 inch DBH or greater, hardwood trees with a 18 inch DBH or greater, or palms with a minimum of 8 foot of clear trunk, shall be used for calculating this requirement. For hardwood trees, every 6 inches or fraction thereof over 18 inch DBH shall count as an additional tree (18 inch DBH = 1 tree, 24 inch DBH = 2 trees, 26 inch DBH = 3 trees, etc.). Slash pine trees and cabbage palms shall only be retained on portions of the property with a density of 8 or more trees per acre. Trees which are unhealthy or dying, as determined by a certified arborist or any individual meeting the qualifications in 3.05.07 H.1.g.iii, shall not be retained or used for calculation. Native slash pine trees shall be retained in clusters, if the trees occur in clusters, with no encroachment (soil disturbance) within the drip line or within 30 feet of the trunk, whichever is greater, of any slash pine or hardwood tree. Encroachment may occur within these distances where evaluation by a certified arborist determines that it will not affect the health of the trees. Trees which die shall be replaced with 10 foot high native canopy trees on a one for one basis. Native trees with a DBH of two feet or more shall be replaced with three 10-foot high native canopy trees. Areas of retained trees shall not be subject to the requirements of 3.05.07 H.
Where trees cannot be retained, the percent requirement of trees shall be made up elsewhere on-site with trees planted in clusters utilizing 10 foot high native canopy trees planted on a one for one basis. Where native trees with a DBH of two feet or more cannot be retained, a minimum of three 10-foot high native canopy trees shall be planted per tree removed of this size. Trees planted to satisfy this requirement shall be planted in open space areas equivalent in size to the area of canopy of the trees removed. This planted open space shall be in addition to the area used to satisfy the minimum landscape requirements pursuant to 4.06.00. In lieu of using actual canopy coverage, the following average diameter for tree canopies may be used to calculate canopy coverage of existing trees: slash pine 40 feet, cypress 25 feet, live oak 60 feet and cabbage palm 10 feet. Open space areas not normally planted with trees, such as stormwater retention areas or lake banks not planted to meet the LSPA requirement, may be used to satisfy this requirement. Trees planted to satisfy this requirement shall be set back a minimum of 30 feet from principal structures and impervious parking areas.
3.
Areas that fulfill the native vegetation retention standards and criteria for native vegetative communities of this section shall be set aside as preserve areas, subject to the requirements of LDC section 3.05.07 H. State and Federal parks, preserves, and forests are subject to compliance with the minimum native vegetation retention requirements of this section; however, such lands are not required to be designated as preserves and are exempt from the requirements of LDC section 3.05.07 H.
4.
Native vegetation to be retained as preserve areas shall be selected in such manner as to preserve the following, in descending order of priority, except to the extent that preservation is made mandatory in sections 3.05.07 F.3 and 3.05.07 G.3.c:
a.
Wetland or upland areas known to be utilized by listed species or that serve as corridors for the movement of wildlife;
b.
Xeric Scrub, Dune and Strand, Hardwood Hammocks;
c.
Onsite wetlands having an accepted functionality WRAP score of at least 0.65 or a Uniform Wetland Mitigation Assessment Score of at least 0.7;
d.
Any upland habitat that serves as a buffer to a wetland area as defined in section 3.05.07 A.3.c above;
e.
Dry Prairie, Pine Flatwoods; and
f.
All other native habitats.
5.
Preservation areas shall be interconnected within the site and to adjoining off-site preservation areas or wildlife corridors.
6.
Where vegetation has been illegally cleared, the amount of native vegetation used to calculate the preservation requirement will be that amount present at the time prior to the illegal clearing. Criteria to determine the process and criteria for the clearing are found in sections 10.02.06 and 3.05.05.
a.
Re-creation of native vegetation shall not be required when any one of the following criteria is met:
i.
The parcel was issued a County permit to clear vegetation and remains cleared of native vegetation .
ii.
The parcel was issued a County permit to clear vegetation for agricultural purposes prior to July 1993 (the date at which the 10 year agricultural clearing rezone limitation previously identified in the GMP is achieved) and which remains cleared of native vegetation .
iii.
If no clearing permit can be found, demonstrations of continuous bona fide agricultural operation along with issuance of an after-the-fact agricultural clearing permit from the County will be evidence of legal clearing. Demonstrations of continuous bona fide agricultural activities may include, but are not limited to, agricultural classification records from the property appraiser's office; dated aerial photographs; occupational license for agricultural operation; SFWMD consumptive use permits for the ongoing agricultural use or other information such as sworn testimony from previous owners which establishes the commencement date and the location of the agricultural operation. The rezone limitation pursuant to 10.02.06 shall apply.
7.
Unless otherwise required in the RFMU District , single-family residences shall be exempt from the native vegetation retention requirements and from having on site preserves. Setbacks to preserves shall be in accordance with 3.05.07 H.
8.
Development standards pursuant to section 4.02.14 shall apply to all development , including single-family , within the ACSC.
9.
Created preserves are allowed subject to the criteria in 3.05.07 H.
10.
Fire and fuel breaks within preserves, kept to the minimum necessary in accordance with standard forestry practice, shall count toward the minimum native vegetation retention requirement.
B.
Specific standards applicable outside the RFMU and RLSA districts. Outside the RFMU and RLSA Districts, native vegetation shall be preserved on site, except for single family residences, through the application of the following preservation and vegetation retention standards and criteria. The single family exception is not to be used as an exception from any calculations regarding total preserve area for a development containing single family lots . For properties not previously within the Coastal High Hazard Area but now within the Coastal High Hazard Area due to adoption of a revised Coastal High Hazard Area boundary in 2013, the native vegetation preservation and retention standards of the Non-Coastal High Hazard Area shall continue to apply. (Reference the Coastal High Hazard Area Comparison Map in the Future Land Use Element of the Collier County Growth Management Plan.)

2.
Inside rural villages . In RFMU receiving lands designated as a rural village , a density bonus of 0.3 dwelling units per acre shall be granted for each acre of native vegetation preserved on-site that exceeds the requirements set forth in section 3.05.07C., once a density of 2 units per acre is achieved through the use of TDR and bonus credits .
F.
Wetland preservation and conservation.
1.
Purpose. The following standards are intended to protect and conserve Collier County's valuable wetlands and their natural functions, including marine wetlands . These standards apply to all of Collier County, except for lands within the RLSA District. RLSA District lands are regulated in section 4.08.00. wetlands shall be protected as follows, with total site preservation not to exceed those amounts of vegetation retention set forth in section 3.05.07(C), unless otherwise required.
2.
Urban lands. In the case of wetlands located within the Urban designated areas of the County, the County will rely on the jurisdictional determinations made by the applicable state or federal agency in accordance with the following provisions:
a.
Where permits issued by such jurisdictional agencies allow for impacts to wetlands within this designated area and require mitigation for such impacts, this shall be deemed to meet the objective of protection and conservation of wetlands and the natural functions of wetlands within this area.
b.
The County shall require the appropriate jurisdictional permit prior to the issuance of a final local development order permitting site improvements, except in the case of any single-family residence that is not part of an approved development or platted subdivision .
c.
Within the Immokalee Urban Designated Area, there exists high quality wetland system connected to the Lake Trafford/Camp Keais system. These wetlands require greater protection measures and therefore the wetland protection standards set forth in 3.05.07 (F)(3) below shall apply in this area.
3.
RFMU district. Direct impacts of development within wetlands shall be limited by directing such impacts away from high quality wetlands having functionality scores of at least 0.65 WRAP or 0.7 UMAM. This shall be accomplished by adherence to the vegetation retention requirements of LDC section 3.05.07 C above and the following standards:
a.
In order to assess the values and functions of wetlands at the time of project review, applicants shall rate the functionality of wetlands using the Unified Wetland Mitigation Assessment Method set forth in F.A.C. 62-345. For projects that have already been issued an Environmental Resource Permit by the state, the County will accept wetlands functionality assessments that are based upon the South Florida Water Management District's Wetland Rapid Assessment Procedures (WRAP), as described in Technical Publication Reg 001 (September 1997, as update August 1999). The applicant shall submit to County staff these respective assessments and the scores accepted by either the South Florida Water Management District or Florida Department of Environmental Protection.
b.
Wetlands documented as being utilized by listed species or serving as corridors for the movement of wildlife shall be preserved on site, regardless of whether the preservation of these wetlands exceeds the acreage required in section 3.05.07 C.
c.
Existing wetland flowways through the project shall be maintained, regardless of whether the preservation of these flowways exceeds the acreage required in section 3.05.07 C.
d.
Drawdowns or diversion of the ground water table shall not adversely change the hydroperiod of preserved wetlands on or offsite. Detention and control elevations shall be set to protect surrounding wetlands and be consistent with surrounding land and project control elevations and water tables. In order to meet these requirements, projects shall be designed in accordance with Sections 4.2.2.4, 6.11 and 6.12 of SFWMD's Basis of Review, January 2001.
e.
Single family residences shall follow the requirements contained within Section 3.05.07 F.5.
f.
Preserved wetlands shall be buffered from other land uses as follows:
i.
A minimum 50-foot vegetated upland buffer adjacent to a natural water body.
ii.
For other wetlands a minimum 25-foot vegetated upland buffer adjacent to the wetland .
iii.
A structural buffer may be used in conjunction with a vegetative buffer that would reduce the vegetative buffer width by 50%. A structural buffer shall be required adjacent to wetlands where direct impacts are allowed. A structural buffer may consist of a stem-wall, berm , or vegetative hedge with suitable fencing.
iv.
The buffer shall be measured landward from the approved jurisdictional line.
v.
The buffer zone shall consist of preserved native vegetation . Where native vegetation does not exist, native vegetation compatible with the existing soils and expected hydrologic conditions shall be planted.
vi.
The buffer shall be maintained free of Category I invasive exotic plants, as defined by the Florida Exotic Pest Plant Council.
vii.
The following land uses are considered to be compatible with wetland functions and are allowed within the buffer :
a)
Passive recreational areas, boardwalks and recreational shelters;
b)
Pervious nature trails;
c)
Water management structures ;
d)
Mitigation areas;
e)
Any other conservation and related open space activity or use which is comparable in nature with the foregoing uses.
g.
Mitigation. Mitigation shall be required for direct impacts to wetlands in order to result in no net loss of wetland functions , in adherence with the following requirements and conditions:
i.
Mitigation Requirements:
a)
Loss of storage or conveyance volume resulting from direct impacts to wetlands shall be compensated for by providing an equal amount of storage or conveyance capacity on site and within or adjacent to the impacted wetland .
b)
Prior to issuance of any final development order that authorizes site alteration, the applicant shall demonstrate compliance with a) and d) of this subsection. If agency permits have not provided mitigation consistent with this Section, Collier County will require mitigation exceeding that of the jurisdictional agencies.
c)
Mitigation requirements for single-family lots shall be determined by the State and Federal agencies during their permitting process, pursuant to the requirements of subsection 3.05.07 F.4 below.
d)
Preserved or created wetland or upland vegetative communities offered as mitigation shall be placed in a conservation easement in accordance with 3.05.07 H.1.d, provide for initial removal of Category I Invasive Exotic Vegetation as defined by the Florida Exotic Pest Plant Council and provide for continual removal of exotic vegetation .
ii.
Mitigation Incentives: A density bonus of 10% of the maximum allowable residential density , a 20% reduction in the required open space acreage, a 10% reduction in the required native vegetation , or a 50% reduction in required littoral zone requirements may be granted for projects that do any of the following:
a)
Increase wetland habitat through recreation or restoration of wetland functions , of the same type found on-site, on an amount of off-site acres within the Rural Fringe Mixed Use District Sending Lands, equal to, or greater than 50% of the on-site native vegetation preservation acreage required, or 20% of the overall project size, whichever is greater;
b)
Create, enhance or restore wading bird habitat to be located near wood stork, and/or other wading bird colonies, in an amount that is equal to, or greater than 50% of the on-site native vegetation preservation acreage required, or 20% of the overall project size, whichever is greater; or
c)
Create, enhance or restore habitat for other listed species, in a location and amount mutually agreeable to the applicant and Collier County after consultation with the applicable jurisdictional agencies.
iii.
EIS Provisions. When mitigation is proposed, the EIS shall demonstrate that there is no net loss in wetland functions as prescribed above.
4.
Estates, rural-settlement areas, and ACSC. In the case of lands located within Estates Designated Area, the Rural Settlement Area, and the ACSC, the County shall rely on the wetland jurisdictional determinations and permit requirements issued by the applicable jurisdictional agency, in accordance with the following:
a.
For single-family residences within Southern Golden Gate Estates or within the Big Cypress Area of Critical State Concern, the County shall require the appropriate federal and state wetland -related permits before Collier County issues a building permit.
b.
Outside of Southern Golden Gate Estates and the Area of Critical State Concern, Collier County shall inform applicants for individual single-family building permits that federal and state wetland permits may be required prior to construction. The County shall also notify the applicable federal and state agencies of single family building permits applications in these areas.
5.
RLSA district. Within the RLSA District, wetlands shall be preserved pursuant to section 4.08.00.

Open spaces as buffers .
i.
The uses in paragraph (a)(ii) above are encouraged to be located as to provide a buffer between the natural reservation and more intensive open space uses, including playgrounds, tennis courts, golf courses (excluding roughs maintained in a natural state), and other recreational uses and yards for individual lots or parcels , or open space uses that are impervious in nature. These more intensive open space uses may not be located closer than 300 feet to the boundary of the natural reservation .
ii.
In addition, where woodstork ( Mycteria americana ) rookeries, bald eagle ( Haliaeetus leucocephalus) nests, and wading bird roosts are found in the adjacent natural reservation , the open space uses identified in (a) - (c) below are considered acceptable for placement within a buffer as specified below:
(a)
Woodstork ( Mycteria americana ) rookeries, bald eagle ( Haliaeetus leucocephalus) nests - 1,500 feet;
(b)
Wading bird roost - 300 feet;

H.
Preserve standards.
1.
Design standards.
a.
Identification. Native vegetation that is required to be preserved or mitigated pursuant to 3.05.07 A. through F. shall be set-aside in a Preserve and shall be identified in the following manner:
i.
The Preserve shall be labeled as "Preserve" on all site plans.
ii.
If the development is a PUD, the Preserve shall be identified on the PUD Master Plan, if possible. If this is not possible, a minimum of 75% of the preserves shall be set-aside on the PUD Master Plan with the remaining 25% identified at the time of the next development order submittal.
iii.
The Preserve shall be identified at the time of the first submittal for a development order that requires the approval of a site plan or conceptual site plan.
b.
Minimum dimensions. Thin linear and perimeter "picture frame-shaped" preserves are discouraged, unless such preserve shapes are dictated by environmental or environmental regulatory considerations. Connections to other preserves, conservation areas, natural flowways, natural water bodies, water management lakes, estuaries, government owned or targeted lands for preservation purposes or existing listed wildlife habitat, when present, are encouraged to establish the largest contiguous natural area possible.
The following minimum widths shall apply:
i.
Twenty feet, for property less than 10 acres.
ii.
An average of 30 feet in width but not less than 20 feet in width, for property equal to 10 acres and less than twenty acres.
iii.
An average of 50 feet in width but not less than 20 feet for property of twenty acres and greater.
iv.
If the existing native vegetation does not meet the minimum dimensions specified above and is required to be preserved pursuant to the preserve selection criteria in section 3.05.07, then the existing native vegetation may be used to satisfy the preservation requirement.
c.
Protection of wetland hydroperiods. Drawdowns or diversion of the ground water table shall not adversely change the hydroperiod of preserved wetlands on or offsite. Detention and control elevations shall be set to protect surrounding wetlands and be consistent with surrounding land and project control elevations and water tables. In order to meet these requirements, projects shall be designed in accordance with Sections 4.2.2.4, 6.11 and 6.12 of SFWMD's Basis of Review, January 2001.
d.
Preserve mechanisms. All preserve areas shall be designated as preserves on all site plans.
On-site County required preserves shall be dedicated to the County as non-exclusive conservation easements without placing on the County the responsibility for maintenance of the preserve area, and the easement conveyance to the County shall include the right of access from existing road right-of-way . The easement shall dedicate the responsibility of maintenance to a property owners association or similar entity, and it shall contain allowable uses and limitations to protect the preserve. All preserve areas shall be shown on the preliminary and final plats in accordance with section 10.02.04, with language similar to Section 704.06 F.S.
No individual residential or commercial lot , parcel lines, or other easements including, but not limited to, utility or access easements that are not compatible with allowable uses in preserve areas, may project into a preserve area.
State and federal parks and preserves shall not be required to place their preserves in a conservation easement .
Any conservation easement or other document restricting uses in a preserve area shall contain the following statement (consistent with CCME GMP Policy 1.1.6):
"Oil extraction and related processing operations are uses which are exempt from the restrictions herein and shall remain allowed uses on the lands described herein."
e.
Created preserves. Although the primary intent of GMP CCME Policy 6.1.1 is to retain and protect existing native vegetation , there are situations where the application of the retention requirements of this Policy is not possible. In these cases, creation or restoration of vegetation to satisfy all or a portion of the native vegetation retention requirements may be allowed. In keeping with the intent of this policy, the preservation of native vegetation off site is preferable over creation of preserves. Created Preserves shall be allowed for parcels that cannot reasonably accommodate both the required on-site preserve area and the proposed activity.
i.
Applicability. Criteria for determining when a parcel cannot reasonably accommodate both the required on-site preserve area and the proposed activity include:
(a)
Where site elevations or conditions requires placement or removal of fill thereby harming or reducing the survivability of the native vegetation in its existing locations;
(b)
Where the existing vegetation required by this policy is located where proposed site improvements are to be located and such improvements cannot be relocated as to protect the existing native vegetation ;
(c)
To provide for flood plain compensation as required by the LDC.
(d)
When a State or Federal permit requires creation of native habitat on site. The created preserve acreage may fulfill all or part of the native vegetation requirement when preserves are planted with the appropriate strata; using the criteria set forth in Created Preserves. This exception may be granted, regardless of the size of the project.
(e)
When small isolated areas (of less than ½ acre in size) of native vegetation exist on site. In cases where retention of native vegetation results in small isolated areas of ½ acre or less, preserves may be planted with all three strata; using the criteria set forth in Created Preserves and shall be created adjacent existing native vegetation areas on site or contiguous to preserves on adjacent properties. This exception may be granted, regardless of the size of the project. Created preserves may exceed the ½ acre size limitation for golf course conversion applications in accordance with LDC section 5.05.15.
(f)
When an access point to a project cannot be relocated. To comply with obligatory health and safety mandates such as road alignments required by the State, preserves may be impacted and created elsewhere on site.
(g)
To provide for connections to on or off site preserves.
(h)
In the RFMU District where upland buffers required by the LDC, lack native vegetative communities.
(i)
Archeological/historical sites where such sites are authorized by the BCC as part of a PUD rezone, to be planted with native vegetation in accordance with the criteria herein.
ii.
Approved created preserves may be used to recreate:
a)
not more than one acre of the required preserves if the property has less than twenty acres of existing native vegetation .
b)
not more than two acres of the required preserves if the property has equal to or greater than twenty acres and less than eighty acres of existing native vegetation .
c)
not more than 10% of the required preserves if the property has equal to or greater than eighty acres of existing native vegetation .
iii.
The minimum dimensions shall apply as set forth in 3.05.07 H.1.b.
iv.
All perimeter landscaping areas that are requested to be approved to fulfill the native vegetation preserve requirements shall be labeled as preserves and shall comply with all preserve setbacks .
v.
Preparation of required planting plans for preserves. Preserve planting plans shall be designed by an individual with academic credentials and experience in the area of environmental sciences or natural resource management. Academic credentials and experience shall be a bachelor's or higher degree in one of the biological sciences with at least two years of ecological or biological professional experience in the State of Florida.
vi.
Planting requirements for created preserves. Soils compatible with the habitat to be created shall be used to create the preserve. Where compatible soils are not present, a minimum of 6 to 8 inches of compatible soil shall be used.
Where created preserves are approved, the planting plan shall re-create a native plant community in all three strata (ground cover, shrubs and trees), utilizing larger plant materials to more quickly re-create the lost mature vegetation. Environments which do not normally contain all three strata shall only be required to plant the strata found in the habitat to be created. Plant material shall be planted in a manner that mimics a natural plant community and shall not be maintained as landscaping. Such re-vegetation shall include the following minimum sizes: one gallon ground cover; 7 gallon shrubs; canopy trees in the following sizes: 25 percent at 10 feet, 50 percent at 8 feet and 25 percent at 6 feet. Spacing requirements for calculating the number of plants shall be as follows: 20 to 30 foot on center for trees with a small canopy (less than 30 feet mature spread) and 40 to 50 foot on center for trees with a large canopy (greater than 30 feet mature spread), 10 foot on center for shrubs, 3 foot on center for ground covers which spread by rhizomes or creeping stems or which have a mature height of 2 feet or more, excluding the bloom, and 2 foot on center for ground covers with a mature height of less than 2 feet, excluding the bloom, and which reproduce primarily by seed.
Minimum sizes for plant material may be reduced for scrub and other xeric habitats in order to promote diversity or where smaller size plant material is better suited for re-establishment of the native plant community. Coverage of pine and hardwoods in scrub habitats shall occupy no more than 70% of the area of a scrub preserve, in order to create natural open areas for wildlife and native ground covers. In south Florida slash pine dominated environments, where fire is a concern, the amount of mid-story vegetation planted may be reduced to promote the growth of native ground covers, reduce the threat of wildfire and to promote use of the preserve by listed species.
Three gallon container saw palmetto ( Serenoa repens ) may be used in lieu of seven gallon containers. South Florida slash pine ( Pinus elliottii var. densa ) trees may be planted in the following sizes: 25 percent at 6 feet and 75 percent at 4 feet, with a spacing requirement of 40 feet on center for calculating the number of slash pines to be planted.
Mangrove trees may be planted as three gallon size containers but must be planted a minimum of five to seven foot on center for calculating the number of mangroves to be planted, if planted at this size. Ground covers in estuarine and other aquatic environments may be planted as liners or bare root plants.
Where archeological/historical sites are counted towards the minimum native vegetation retention requirement and where such sites have no native vegetation or the native vegetation is authorized to be cleared and excavated by the BCC as part of a PUD rezone, these sites shall be re-vegetated with native vegetation similar to or compatible with the native vegetation in the preserve or on the archeological/historical site. Re-vegetation shall only be with ground covers in one-gallon containers unless otherwise approved by the BCC.
Upland or seasonally wet preserves with extended dry periods shall detail a method of providing water until the plants are established.
vii.
Supplemental planting requirements within preserves. Supplemental plantings in the strata required to restore the habitat to its natural condition shall be added to preserves where prior clearing or disturbance, or the removal of non-native and/or nuisance vegetation has created open areas with little or no native vegetation . Plant material shall be planted in a manner that mimics a natural plant community and shall not be maintained as landscaping. Supplemental plantings must be of the species typical of the native habitats being restored and take into consideration the requirements of any listed species using the preserve.
Areas defined as " native vegetation " pursuant to this section and required to be retained as preserves, shall only be required to plant material in the sizes specified in this subsection and not in the sizes required for created preserves. Supplemental plantings within preserves shall be in accordance with requirements specified in approved state and federal permits for a project. Where not specified in the State and Federal permits for a project, supplemental plantings within County required preserves shall adhere to the following minimum standards: one gallon or liner ground covers, three gallon shrubs and four foot high trees. Ground covers in aquatic environments may be planted as bare root plants.
Natural recruitment of native groundcovers may be used in areas where native groundcovers would be expected to regenerate on their own. If within a two-year period the coverage of ground covers is less than that typically found in environments containing these species, then supplemental planting with native ground covers or distribution of native seed shall be required. A planting plan with schedule for planting or distributing native seed shall be included as part of the preserve management plan, in case sufficient natural recruitment of groundcovers has not occurred.
Natural recruitment of south Florida slash pine ( Pinus elliottii var. densa ) may be used where south Florida slash pine would be expected to regenerate on their own. If within a two-year period the number of pine seedlings is less than that needed to regenerate the habitat type, then supplemental planting with south Florida slash pine or distribution of south Florida slash pine seed shall be required. A backup planting plan with schedule for planting or distributing seed shall be included as part of the preserve management plan, in case sufficient natural recruitment has not occurred. South Florida slash pine trees may be planted as seedlings in lieu of planting four foot high trees, for individual preserves 100 or more acres in size.
Restoration of mangroves shall be with one- to three-gallon container mangroves, unless otherwise permitted by State and Federal permitting agencies.
Minimum sizes for plant material may be reduced for scrub and other xeric habitats in order to promote diversity or where smaller size plant material is better suited for re-establishment of the native plant community. Coverage of pine and hardwoods in scrub habitats shall occupy no more than the 70% of the area of a scrub preserve, in order to create natural open areas for wildlife and indigenous ground covers.
viii.
Success criteria. Success shall be demonstrated for created preserves and supplemental planting within preserves, 5 years after installation of plant material and shall be included with the monitoring report. Before and after photos taken from specific or permanent field markers to identify the locations within the preserve shall be included in the above mentioned monitoring report. Demonstration of success shall include the following:
a)
80% vegetative coverage has been attained within the preserve.
b)
Native vegetation is within the range of species diversity, density and distribution documented within either reference sites or from literature references for the specific habitat types.
c)
Native vegetation characteristic of the habitat are reproducing in the vegetative or seeding manner typical of the species.
d)
When permitted through the Water Management District using UMAM, overall UMAM scores must indicate that the preserves have attained or are clearly trending toward the "with-mitigation" scores used to determine success.
f.
Off-site vegetation retention.
i.
Purpose and Intent. The purpose of this subsection f. is to identify the criteria to satisfy on-site preserve requirements off site. The intent of the on-site preserve requirement is to retain, maintain, and preserve existing native vegetation on site as provided for in the Conservation and Coastal Management Element of the GMP. However, in limited situations on-site preserve may be considered less viable as a functional preserve if it is 21,780 square feet (one-half acre) or less and isolated. Therefore, in limited situations, providing for a preserve off site can achieve the goals and objectives of the GMP. This section shall not apply to lands located within the RLSA or RFMU districts.
ii.
Applicability and prohibitions. Except where it is prohibited, applicants may request that the on-site native vegetation retention requirement be satisfied in full off site where the native vegetation requirement is 21,780 square feet (one-half acre) or less, and the preserves have not been identified on an approved development order by the County. Off-site preserves are prohibited if one or more of the following is found on site:
a)
Xeric scrub, hardwood hammocks, mangrove (excluding mangrove fringes less than 40 feet in width, as measured from the root line, on artificially created shorelines), coastal dune and strand environments, and listed species habitat or corridors per the requirements or recommendations of the FFWCC or USFWS;
b)
Preserves that are located within or contiguous to natural flowways required to be retained per the requirements of the SFWMD, natural water bodies, estuaries, government required preserves (not meeting the off-site preservation criteria herein), NRPAs, or contiguous to property designated for purchase by Conservation Collier or purchased by Conservation Collier, or contiguous to properties containing listed species nests, buffers, corridors and foraging habitat per the requirements or recommendations of the FFWCC or USFWS. For the purpose of this section, natural flowways shall also include those identified during wetland permitting with applicable State and Federal agencies, regional drainage studies, or surface water management permits; or
c)
The on-site native vegetation retention requirement is greater than 21,780 square feet (one-half acre).
iii.
Off-site preserves approved administratively. Except as limited in LDC section 3.05.07 H.1.f.ii., the County Manager or designee may approve deviations to meet the on-site preserve requirements off site in only the following four situations:
a)
Essential services facilities;
b)
Affordable housing approved by the Collier County Community and Human Services Division;
c)
Projects where on-site native vegetation is fragmented; or
d)
Projects where on-site native vegetation is not contiguous to off-site preserve areas.
iv.
Off-site preserves approved through a public hearing. Except as limited in LDC section 3.05.07 H.1.f.ii., applicants may request a PUD deviation or variance, as applicable, to meet the on-site preserve requirement off site.
a)
PUD deviations shall be processed in accordance with the procedures in LDC section 10.02.13.
b)
Variances shall be processed in accordance with the procedures in LDC section 10.09.00.
v.
For the purposes of this section, the preserve requirement shall be based on the total acreage for the PUD or development order, as applicable, and not based on an individual phase or phases of a development, consistent with LDC section 3.05.07 H.1.a. If the on-site native vegetation retention requirement is satisfied off site, then all of the required preserve will be satisfied off site.
vi.
Off-site Alternatives. Off-site native vegetation retention requirements may be satisfied by monetary payment or by land donation.
a)
Monetary payment alternative. Applicants shall make monetary payment to Collier County. Such funds shall be used by the County for the purchase and management of off-site conservation lands within the county. The monetary payment amount shall be based on the post development appraisal value per acre multiplied by the preserve requirement, then multiplied by 1.25 to establish the endowment amount. The appraisal shall be performed by a state certified appraiser. In addition, the fee for initial exotic vegetation removal shall be paid by the applicant as established in the Parks and Recreation Division Fee Schedule. This monetary payment shall be made prior to the preconstruction meeting for the SDP or final plat construction plans.
b)
Land donation alternative. In lieu of monetary payment, applicants may choose to donate land for conservation purposes at a ratio of 4:1 to Collier County or to another government agency. In the event of donation to Collier County, the applicant may acquire and subsequently donate land within the project boundaries of Winchester Head, North Golden Gate Estates Unit 53, another multi- parcel project or any other land designated by Conservation Collier donation acceptance procedures.
i)
Applicants who choose to donate land shall be required to demonstrate that the land to be donated contains native vegetation communities equal to or of higher priority (as described in subsection 3.05.07 A.) than the land required to be preserved onsite. In no case shall the acreage of land donated be less than the acreage of land required to be preserved onsite. Land donated to satisfy the off-site vegetation retention requirement must be located entirely within Collier County. Donations of land for preservation shall be made to a federal, state or local government agency established or authorized to accept lands for the conservation and management of land in perpetuity, subject to the policies and procedures of the receiving entity. Lands donated to Collier County must include a cash endowment for management of the land. The cash endowment shall be established in the Collier County Parks and Recreation Division Fee Schedule. Applicants shall provide evidence that donations of land for preservation and endowments for management have been accepted by and donated to the entity stated above, at the time of the preconstruction meeting for the SDP or final plat and construction plans. State and Federal agency requirements for mitigation, remediation and monitoring for the donated land shall be the responsibility of the applicant.
vii.
PUD zoning. Preserves or portions of preserves identified on a PUD master plan shall require an amendment to the PUD master plan to use the native vegetation retention alternative, subject to LDC section 10.02.13 E., unless the option to use the off-site native vegetation retention alternative is included in the PUD.
viii.
Deviations or variances from LDC section 3.05.07 H.1.f. are prohibited.
g.
Preserve management plans. Criteria i, ii, vii and viii below are required for all preserves whether a management plan for the preserve is required or not. Preserve Management Plans shall be required for all properties with 5 acres or more of preserve or where listed species are utilizing the preserve or where the preserve contains habitat which requires management for fire (such as Pine Flatwoods, Palmetto Prairie or Scrub). The Preserve Management Plan shall identify actions that must be taken to ensure that the preserved areas will maintain natural diversity and function as proposed. A Preserve Management Plan shall include the following elements:
i.
General Maintenance. Preserves shall be maintained in their natural state and must be kept free of refuse and debris.
ii.
Exotic Vegetation Removal, Non- native Vegetation , and Nuisance or Invasive Plant Control. Exotic vegetation removal and maintenance plans shall require that Category I Exotics be eradicated from all preserves. All exotics within the first 75 feet of the outer edge of every preserve shall be physically removed, or the vegetation cut down to grade , cut debris removed and the stump treated. Exotics within the interior of the preserve may be approved to be treated in place if it is determined that physical removal might cause more damage to the native vegetation in the preserve. When exotic vegetation is removed, but the base of the vegetation remains, the base shall be treated with an U.S. Environmental Protection Agency approved herbicide and a visual tracer dye shall be applied. Any person who supervises up to eight people in the application of pesticides and herbicides in the chemical maintenance of exotic vegetation in preserves, required retained native vegetation areas, wetlands , or LSPA shall maintain the Florida Dept. of Agriculture and Consumer Services certifications for Natural Areas Pesticide Applicators or Aquatic Herbicide Applicators dependent upon the specific area to be treated. Control of exotics shall be implemented on a yearly basis or more frequently when required, and shall describe specific techniques to prevent reinvasion by prohibited exotic vegetation of the site in perpetuity. Nuisance or invasive plants and non-native ornamental vegetation shall be eradicated from all preserves.
iii.

iv.
Wildlife Habitat Management. Where habitats must be managed with regards to the species utilizing them, Wildlife Habitat Management strategies may be required to provide for specialized treatment of the preserve. Where protected species are identified, management strategies shall be developed and implemented in accordance with section 3.04.00. The County will accept state and federal management plans that are consistent with the requirements of the LDC. Hunting is permissible in preserves where expressly approved by the Board of County Commissioners.
v.
Fire Management. Special land management practices to control fire or to maintain species diversity in the absence of fire must be included as part of the Preserve Management Plan, for those habitats requiring these practices. Fire Management plans may include removal of dead vegetation or periodic thinning of living vegetation, to improve forest health and mimic the natural effects of fire, as appropriate for the habitat type and surrounding land uses. Fuel and fire breaks shall be kept to a minimum necessary to control fire and should be coordinated with the State of Florida, Division of Forestry, as part of a fire suppression plan. The annual inspection monitoring report required pursuant to ix (below) shall document, with photographs, the coverage and types of vegetation to be cleared for fuel management, prior to clearing. Where listed species have been documented within the preserve, the annual inspection monitoring report shall require surveys for the nests, burrows or cavities of listed species that may be affected by the land management practices, no more than six months prior to clearing, if gopher tortoises occur in the area, or within the time frames recommended by the FFWCC and USFWS. Fire Management plans shall be consistent with wildlife habitat management plans approved by Collier County.
vi.
Vegetation Removal Permits. Vegetation Removal Permits shall not be required to implement Preserve Management Plans and firewise safety plans that specify land management practices for clearing for fuel management or fire lines in accordance with normal forestry practices and which have been approved pursuant to this section. State and Federal agency permits or approvals shall be required, where applicable, prior to clearing.
Vegetation Removal Permits shall not be required to remove dead, dying or leaning trees which pose a safety concern, unless they contain a nest or cavity of a listed animal species or bald eagle. The annual inspection monitoring report required pursuant to ix (below) shall document, with photographs, trees to be removed for safety concerns.
vii.
Protection During Construction and Signage After Construction. The Preserve Management Plan shall address protective measures during construction and signage after construction that are consistent with LDC section 3.05.04.
viii.
Monitoring for Preserves Receiving Treated Stormwater. A monitoring program must be implemented for preserves that will receive stormwater pursuant to the requirements of section 3.05.07. The monitoring program must include protocols to conduct vegetation surveys and monitoring for ground and surface water levels. The Preserve Management Plan shall include a schedule requiring a baseline monitoring report followed by 5 annual monitoring reports. Monitoring reports for stormwater within preserves shall be included as part of the annual inspection monitoring reports pursuant to ix. (below). The County will accept wetland monitoring reports submitted to the South Florida Water Management District as long as the reports conform to the minimum requirements provided herein and includes all of the Preserves receiving stormwater. Compatible vegetation must be planted to replace upland vegetation that may be lost as a direct result of the introduction of stormwater into the preserve.
ix.
Inspections and Monitoring. The property owner shall provide for inspections of all on-site preserves by the Preserve Manager on an annual basis, at a minimum, or more frequently when required to ensure the preserve functions as intended. The results of the inspections, and recommendations of the Preserve Manager, must be included in a monitoring report on an annual basis, at a minimum. The property owner shall retain copies of the five most recent years of monitoring reports and make them available to Collier County upon request.

xi.
The requirements of criteria v, vi, viii, ix, and x shall not apply to projects with County permits or approvals including approved Preserve Management Plans issued prior to June 8, 2010.
h.
Allowable uses within County required preserves. Passive uses are allowed within preserves to provide for access to the preserve, as long as any clearing required to facilitate these uses does not impact the minimum required native vegetation or cause loss of function to the preserve. Loss of function to the preserve includes unacceptable changes in vegetation within the preserve or harming any listed species present in the preserve. Unacceptable changes in vegetation within preserves include replacement of indigenous vegetation with non-native species, changes in vegetative composition which are inconsistent with target plant communities or die-offs of vegetation which are inconsistent with target plant communities. Determinations of harm to listed species shall be made by FFWCC or USFWS, and pathways , structures or improvements within preserves containing listed species shall be in accordance with permits or authorizations from these agencies.
i.
The following passive uses are allowed within preserves.
