LDC Amendment Request
ORIGIN: Community Development and Environmental Services Division
AUTHOR: Barbara Burgeson, Principal Environmental Specialist
DEPARTMENT: Environmental Services
AMENDMENT CYCLE# OR DATE: Cycle 1, 2006
LDC PAGE: LDC 3:36
LDC SECTION: Section 3.05.07.H.1.d. Allowable uses in preserves
CHANGE: Add criteria to allow for treated stormwater within wetland or hydric
preserve areas when the additional stormwater will either benefit the preserve or will
have no negative impact on the native vegetation or listed species in the preserve or to the
uplands or listed species within or adjacent to the preserve.
REASON: There are times when it is appropriate for stormwater to be directed into
preserves and this amendment defines those times.
FISCAL & OPERATIONAL IMPACTS: This will reduce the time staff spends on
requests of this type since there will be criteria to utilize.
RELATED CODES OR REGULATIONS: None
GROWTH MANAGEMENT PLAN IMPACT: None
OTHER NOTES/VERSION DATE: This version dated March 10, 2006; amended
June 15, 2006; July 10, 2006; September 1, 2006, September 6, 2006.
Amend the LDC as follows:
3.05.07 Preservation Standards.
H. Preserve standards.
1. Design standards.
* * * * * * * * * * *
* *
h. Allowable uses within preserves. For the purposes of this
Section, preserves are those areas that fulfill the native
vegetation retention standards and criteria of Section
3.05.07. Only the following uses subject to the associated
design criteria have been determined to ensure that the
ecological functions of the preserves are maintained and are
allowed within preserves.
i. Passive recreational uses subject to the following
criteria.
a) Passive recreational uses are allowed within
preserves, as long as any clearing required to
facilitate these uses does not impact the
minimum required native vegetation. These
uses would allow limited access to the
preserve, in a manner that will not cause any
negative impacts to the preserve, such as
pervious pathways, benches and educational
signs. Fences may be utilized outside of the
preserves to provide protection in the
preserves in accordance with the protected
species section 3.04.01 D.l.c. Fences and
walls are prohibited within the preserve.
ii. Treated stormwater subject to the following criteria.
a) Treated stormwater shall be allowed only in
preserves that are comprised of
jurisdictional wetlands, uplands comprised
solely of hydric soils as mapped in the Soil
Survey of Collier County Area, Florida,
(USDA, 1998), uplands that serve as buffers
around the wetland, in accordance with the
approved SFWMD Environmental Resource
Permit (ERP), or a combination thereof.
b) Stormwater shall not be discharged into
upland preserves utilized by listed species.
Stormwater shall be allowed in jurisdictional
wetland preserves with listed species, but
shall have no negative impact on those listed
species.
c) Stormwater entering the preserve must be
treated to meet the water quality volumetric
requirements of Section 5.2.1(a) of the Basis
of Review For Environmental Resource
Permit Applications Within the South
Florida Water Management District,
(SFWMD February 2006). Discharge of
treated stormwater into a preserve shall be in
a controlled manner to prevent erosion,
scour, and to promote even distribution.
d) When stormwater is allowed in preserves,
the associated stormwater facilities such as
berms, swales, or outfall structures, may be
located within the preserve, but the area of
such facilities can not count towards the
native vegetation preservation requirement
pursuant to Section 3.05.07 of the LDC.
These facilities are not subject to setback
requirements as found in Section
3.05.07.H.3 of the LDC. These facilities
must be placed under a drainage easement.
e) Where stormwater is allowed in a preserve, the
Preserve Management Plan as required in
Section 3.05.07.H.1.g of the LDC must
address potential maintenance problems and
shall also provide for a monitoring program.
f) Stormwater shall be allowed in upland
preserves in the RLSA - WRA areas in
accordance with section 4.08.00 Rural
Lands Stewardship Area Overlay District
standards and Procedures.
g.) A property owner may request deviations
from the above regulations,
3.05.07.H.l.h.ii. Staff shall review the plans
and proposed deviations to ensure wetlands
in the preserve will receive a benefit and
uplands in the preserve will receive no
adverse impact from the deviations being
proposed. The process for granting
deviations shall follow the procedure as set
forth in the Appeal section (8.06.10) for the
EAC, and shall be heard at a public hearing
of the EAC.
6.1.1.(2) Dimensional Criteria for Preserves
• Adjoining other preserves or conservancy areas or natural features (rivers,
sloughs)
• Reduce number of preserves while maximizing functionality
• Ratio of average width to length of 1:4 (need to specify procedure for calculating
average width)—LDC specifies minimum widths.
• Recommendation of optimal shapes (circle is perfect since it minimizes edge
effects)
• Criteria for permitting multiple preserves
• Minimum size preserves, when multiple preserves present
• Appeal procedures

Comments on Selected LDC Amendments
6.1.1(9) Offsite vegetation retention alternatives
• Minimum size if isolated.
• Relax size rules if adjoining preserve.
• Conditions under which offsite more desirable
• Poor quality
• High traffic area
• Commercial vs residential
• How much of offsite? 3:1?
• Add petition deviation language.
J.Hushon 9/12/2007
6.1.8 EIS Thresholds
• Type of development
■ Size
■ What activities planned onsite
■ Location vs final character
■ Degree of site alterations
• Always required for:
■ Sending lands
■ Seaward of coastal high hazard Area and greater than 2.5 ac
■ ST or ACSC ST Overlays
■ NRPAs
■ Should single family homes be required to do one?
J.Hushon 9/12/2007
7.1.6 Listed Plants Protection
• Reference to listed plant species (can be set of web addresses)
• Preservation rules.
• Relocation for species for which reasonable.
• Management Plan.
