New Business:
Variance: requesting to impact marshland to maintain right of way—Polk Street right of way & 318 Polk
Street—City of Tybee & Michael Leonard —Zone C2 -EC -4-0025-01-005Y & 005Z.
Mr. Shaw approached the Planning Commission and stated that this property has been on the agenda a few
times. The City is seeking to maintain the City's right-of-way in conjunction of working with Mr. Leonard so
he can maintain his driveway. He stated we need to give ourselves the variance and then apply with the State.
The reason we are reapplying for the variance again is that we have not received the pen -nit before the variance
expires. Mr. Alton Brown with Resource and Land consultants working as the agent on behalf of the City of
Tybee Island approached the Planning Commission and stated the Corp of Engineers permit has been obtained
for the road improvements and maintenance. We have also applied to the DNR for a coastal marshlands permit.
He also stated because of the two recent hurricanes and a variety of other things the project review by Coastal
Resources Division has been delayed. Now we are back on track with the review and need to renew the
variance. The DNR line has been surveyed again and will be updated. The scope of the project will stay the
same. Alan Robertson asked how long will this construction take. Mr. Brown stated that the Corp of
Engineers pen -nit is valid until 2022 and the Coastal marshlands permit will be valid for five years from the
day that it is issued. Alan Robertson made a motion to approve. Marianne Bramble seconded. The vote to
approve was unanimous.
Discussion and Presentation:
Carrying Capacity Study Implementation Coastal Incentive Grant — Goodwyn Mills Cawood
Ecological Planning Group — Courtney Reich
Mr. Shaw approached the planning commission and stated Ms. Reich did not show tonight so he would try to
share what he knows about the grant. He stated the coastal incentive grant had three goals or outputs. One a
water and sewer rate setting which has been done and will be looked at. Two would be potential code changes
to reduce density due to water and sewer issues and another to reduce impacts in areas that flood. The one
point Courtney wants to point out is whether we want to make some changes to the code to reduce the potential
density with an example being how a variety of lots that could become two lots. Also changing the 65 percent
buffer greenspace. With the amount of rentals on the Island, there is a big demand to fill every buildable space
on lots. In addition, the pool market has expanded from the rental market and those take up the greenspace.
Mr. Shaw stated those are some of the issues I know Ms. Reich wanted to bring up. Vice Chair Ron Bossick
stated he would like to ask Courtney Reich to come back to Planning Commission at the next meeting so they
can ask the questions they have. Alan Robertson stated that our March meeting would be a good time for
Courtney Reich to come since she will have went to City Council February 28, 2019, that will give us input
from City Council.
Adjournment: Tina Gann made a motion to adjourn. Marianne Bramble seconded. Meeting adjourned at
7:30pm.

Sec. 5-090. - Variances.
(A) Standards. After an application has been submitted to the designated city official, reviewed by
the planning commission, and a public hearing has been held by the mayor and council, the
mayor and council may grant a variance from the strict application of the provisions in this Land
Development Code only if a physical circumstance, condition, or consideration exists as
described in subsection (1).
(1) There are unique physical circumstances or conditions or considerations beyond that of
surrounding properties, including a substandard lot of record that existed prior to March 24, 1971
(see section 3-040); irregularity; narrowness; or shallowness of the lot shape; or exceptional
topographical or other physical circumstances, conditions, or considerations related to the
environment, or to safety, or to historical significance, that is peculiar to the particular property;
and;
(2) Because of such physical circumstances or conditions or considerations, the property cannot
be developed in strict conformity with the provisions of this Land Development Code, without
undue hardship to the property.
(3) A nonconforming use or structure does not constitute a unique physical circumstance,
condition, or consideration.
(B) Height. No part of any structure shall project beyond 35 -feet above the average adjacent
grade of a property except:
(1) ,
elevators, solar panels and similar appurtenanGes needed to operate and MaintaiR the building
nnwhirh they aro IGGat r! Those items specifically excluded from consideration as described in
Section 2-010 Terms and Definitions: Height of building.
(2) The following items that were existing on the date of the adoption of this ordinance: flag poles,
television aerials, water towers and tanks, steeples and bell towers, broadcasting and relay
towers, transmission line towers, and electric substation structures.
(C) Variance longevity. After a variance has been granted by the mayor and council it shall be
valid for a period of 12 months from date of approval. Such approval is based on information
provided in the application. Building permits may only be granted for plans consistent with the
approved application. Any deviation from the information submitted will require separate approval
by the mayor and council.
(D) Reviewing variance applications. The designated city official, planning commission, and
governing body, shall consider the factors stated herein in reviewing variance applications in
taking action on a particular variance. In exercising the powers to grant variances, the mayor and
council may attach any conditions to its approval which it finds necessary to accomplish the
reasonable application of the requirements of these regulations.
(E) Application approval. Notwithstanding any other provisions of this Code of Ordinances, the
designated city official may approve applications for variances without the need of public
hearings and without the need of review by the planning commission or the mayor and council as
follows:
(1) When either of the following circumstances exists:
a. The proposed improvement or alteration will not result in an expansion of the existing footprint
of the existing structure; or
b. No additional encroachment into any setback shall be created by the proposed improvement,
construction or addition.
(2) When each of the following circumstances also exists:
a. No encroachment or construction of habitable space or other prohibited improvements will
exist below one foot above the base flood elevation; and
b. The requested improvements or construction will not violate existing zoning provisions.
This subsection shall have specific application to existing nonconforming
structures as referred to in section 3-020.
(F) Compliance with ordinances. Notwithstanding any other provision of this Code of Ordinances,
no application for a variance may be accepted nor may any variance be granted with respect to
any property that is then not in compliance with the requirements of ordinances for the condition
on which the variance is sought, unless the applicant files with the application a detailed written
explanation of how, when, and by whom the need for a variance was created. In such a case, the
planning commission shall make a recommendation to the mayor and council as to whether the
variance should be approved or rejected or modified and the mayor and council, following a
public hearing, may approve, reject or modify the variance request. In the event property is
constructed in violation of the ordinances, the violation status remains until such time as the
condition is rectified and placed in conformity with the ordinances. Violations of the ordinances
may be subject to the enforcement provisions of this Code and all penalties permissible by law. A
variance that is granted under this section does not excuse prior violations including those that
have resulted or may result in enforcement action by the city.

MEMORANDUM
Savannah, GA 31401
T (912)555-6790
Background
Tybee Island received a Coastal Incentive Grant (CIG) in 2015 to perform a Carrying Capacity
www.gmcnetwork.com
Study of the island to identify issues related to year-round and seasonal population density
www.ecc400calplanning.net
and its impact on island infrastructure and resources. This study resulted in the identification
of a number of key issues related to population growth and seasonal population including: 1)
Limits in the permitted water withdrawal from the Floridan Aquifer; 2) Significant increases in
water withdrawal, wastewater discharge, and solid waste/litter generation during tourism
season; 3) Effects of king tides and sea level rise on the stormwater drainage system; and 4)
Development pressure in the R-2 zoning district, the highest density residential district which
is also subject to king tide flooding. The overall approach recommended by the CCS was
twofold:
Make improvements to the City's existing infrastructure systems to provide
additional capacity to accommodate growth in a more sustainable manner, and
Identify ways to better manage future growth to limit stresses on infrastructure and
impacts to the environment.
Tybee Island subsequently received a CIG in 2018 to implement several of the specific
recommendations of Carrying Capacity Study, which included the following-
1.
ollowing
1. Perform a water & sewer rate study to address needed infrastructure improvements
and "peak usage rates" to encourage water conservation during peak tourism
season, and to prepare for future needed infrastructure investments.
2. Draft revisions to the City's code that will reduce stormwater impacts from new
development.
3. Draft revisions to the City's code that will reduce the density and impact of future
development and direct it away from areas of King Tide flooding.
EPG/GMC has worked with Tybee Island staff and the Masterplan Implementation Committee
over the past year to identify opportunities to make amendments to the City's Zoning code to
address the issues described above. The alternatives are presented below for your
consideration:
Alternative #1: Potential Changes to the R-2 Schedule of Development Regulations (Sec 3-
090)
The greatest opportunity for additional residential development on Tybee Island is within the
R-2 Zoning Category. This category was initially established to allow for one and two-family
residential development. Roughly 40% of the island is currently zoned R-2, much of which is
currently developed as a single-family residential housing. However, the minimum lot size
requirements to subdivide lots to build and develop multi -unit dwellings is reason for concern
as it relates to increased residential density. Since most of the island has been developed,
subdivision and subsequent development of existing single-family residential parcels
presents the greatest opportunity for growth on the island. Recent development activity
indicates that there is a growing trend in R-2 to tear down single-family structures, subdivide,
Page 1 of 7 Build'ngC xnmunit=es
and build at higher densities, i.e. duplexes. This memo evaluates the lot sizes in the R-2
category and recommends potential changes in lot size requirements to reduce the future
density in R2.
The schedule of development regulations (Sec 3-090) defines the allowable lot sizes for
residentially zoned property in the City. The minimum lot size for development of a single-
family dwelling unit is 4,500 squarefeet in the R-2 district. The minimum lotsizefor atwo-family
structure in this district is 6,750 square feet.
Properties currently located in the R-2 zoning district have been broken down into the
following categories based on lot size:
• Less the 6,750 square feet. Parcels in this category could only be developed as single-
family homes.
• 6,750 -11,250 square feet. Parcels in this category could be developed as two-family
residential, either as a duplex, or as two, single-family residential parcels (if over 9,000
square feet).
• 11,250 -13,500 square feet. These parcels could be split and developed with one -
single family and one, two-family structure.
• Over 13,500 square feet. Parcels that can be developed as two, two-family structures.
The following table summarizes the number of parcels and the potential units that could be
developed within each of these categories:
CURRENT

Build -out based on the numbers above could generate 2,959 residential units. Based on the
assumptions in the Carrying Capacity Study, we estimate that the future overnight population
(both residents and short-term rental occupants) in this district, at full build -out, could be
11,363. It is important to consider that much of the R-2 district is in areas subjectto storm surge
and Kingtides. Additional density in this area putsthe property at risk and also impactsTybee's
Emergency Response Operations as homes in this area are at a higher risk to experience
flooding and require evacuation and/or rescue of inhabitants.
The maps on the following pages shows the breakdown of R-2 parcels on Tybee and also show
the flood risk and extent of recent storm surge flooding.

(0'% ( % In an effort to minimize the density of future residential development within areas of the City
01 1 zoned 1-2, we propose modifying the development regulations (Sec 3-090) by changing the
minimum lot size requirements for two family from 6,750 square feet to 9,000 square feet.
Based on this change, R-2 properties would be broken down into the following categories:
• Less the 9,000 square feet. Parcels in this category could only be developed as single-
family homes.
• 9,000 —13,500 square feet. Parcels in this category could be developed as two-family
residential, either as a duplex, or as two, single-family residential parcels.
• 13,500 —18,000 square feet. These parcels could be split and developed with one -
single family and one, two-family structure.
• Over 18,000 square feet. Parcels that can be developed as two, two-family structures.
The following table summarizes the number of parcels and potential units that could be
developed within each of the proposed categories:

JON M 4 Alternative #2: Greenspace Requirements and Impervious Area Coverage
Impervious surface impedes the infiltration of rainfall and can results in stormwater flooding,
particularly during high tide events, when the capacity of the stormwater drainage systems is
extremely limited. The City of Tybee Island Land Development Code requires that all zoning
districts maintain 65% of the designated setback area in a vegetative state (Sec 3-165), i.e. with
no impervious surfaces. This section examines the R-2 zoning district in terms of setbacks and
greenspace requirements to determine how much impervious area exists on a typical R-2
parcel. The average size of a parcel located in the R-2 district is 60 feet x 80 feet (4,800 square
feet). The following setbacks are defined in section 3-090:
• Front = 20 feet
• Rear and Side =10 feet
The figure below illustrates the lot size and setbacks for a subject parcel located in the R-2
district.
80'
60'
With a lot size of 4,800 square feet, 2,800 square feet (area based on setbacks) is subjectto the
greenspace requirements, which means that 1,820 square feet of this lot would be required to
remain in a vegetative state. The illustration below shows what this lot could look like at build
out based on the existing setbacks and greenspace requirements. Based on these
calculations, 60% of the lot would be impervious.
80'
60'
Studies by the Center for Watershed Protection have shown that watersheds with total
impervious coverage exceeding 10-20% can be impacted and those with total impervious
surface coverage exceeding 30% are often degraded. Impervious area also creates hotter
temperatures. Given the amount of king tide flooding that the Island already experiences, and
the potential impacts of additional impervious surfaces related to new development, Tybee
may wish consider increasing the amount of buffer that must remain in a vegetated state or
decreasing the amount of future development allowed.
