REQUEST: Community Development Department presents to the Commission, the second
reading of Ordinance No. 2002-27, which will vacate and abandon a 66.65 foot
long segment of a 5 foot wide utility easement, located along the west side of Lot
10, the Reserve at Tuscawilla, Phase I-A.
PURPOSE: The purpose of this agenda item is to present to the Commission, the second
reading of Ordinance No. 2002-27, which will vacate a 5 foot-wide,
approximately 66.65 foot-long utility easement, located on the west side of Lot
10, Reserve at Tuscawilla, Phase I-A, as recorded in Plat Book 58, Pages 99-100
of the public records of Seminole County, Florida.
CONSIDERATIONS:
The applicant, Austin Homes, requests the vacation of the portion of an un-used
platted utility easement that is not needed for utility provision, now or in the
foreseeable future. The applicant states that the home buyer requests a retaining
wall be constructed within this area of the lot. City policy prohibits constructing a
retaining wall in an easement. Correspondence from utility providers, the legal
description, and a map are provided as attachments.
A similar situation occurred in Parkstone. However, in that situation, the
retaining wall was determined necessary for maintaining the structural integrity of
the house. The applicant states that no retaining wall is required, here, although
one is requested by the home-buyer.
The question arose as to the City's requirements for retaining walls. Section 6-
193 (Chapter 6, Article VII. Fences, Walls, Hedges) of the City Code requires any
fence or wall to be set back at least 3 inches from the property line. The City
October 14, 2002
Public Hearing Item A
Page 2
regulates retaining walls primarily through the Florida Building Code, which the
City's Building Division enforces.
Sections 1608.1.1,1803.1.3, and 1815 of the Florida Building Code (Attachment
C) specify when or where a retaining wall is required to 'support a structure.
Attachment D graphically demonstrates the area adjacent to a structure that must
be filled or maintained with soil as a finish grade. Where the finish grade intrudes
into area comprised of one foot above/beyond an imaginary line extending at a 45
degree angle away from the building foundation ("line of repose"), the Florida
Building Code requires a retaining wall to be constructed to ensure the structural
integrity of the building. Retaining walls must be designed to resist the design
lateral soil loads calculated for various soil types (depicted in the attached Table
1608.1.1 on page 16.5 of the Florida Building Code). The attached Table 1815.4
on page 18.21 ofthe Florida Building Code specifies the thickness and
reinforcement for a particular retaining wall of a certain height holding back soil
with one of the various load calculations from Table 1608.1.1.

1804.2 Soils investigation
J 1804.2.1 Plain concrete, masonry or timber Cootings.
Footings shall be so designed that the allowable bearing
capacity of the soil is not exceeded. If structural plain con-
crete, masonry or timber footings are used, they shall rest
on undisturbed or compacted soil of uniform density and
thickness. Compacted soils shall be tested to a minimum
of <2.5!& of Modified Proctor in accordance with ASTM 0
1557 and compacted and tested in lifts not to exceed 12
inches (305 mm). If sufficient compactibilities exist, soils
may be compacted and tested in greater lift thicknesses.
18.2
.A804.2.2 Questionable soil. Where the bearing capacity
of the soil is not definitely known or is in question, the
building official may require load tests or other adequate
proof as to the permissible safe bearing capacity at that
particular location. To determine the safe bearing capacity
of soil, it shall be tested at such locations and levels as
conditions warrant, by loading an area not less than 4 sq ft
(0.37 m2) to not less than twice the maximum bearing
capacity desired for use. Such double load shall be sus-
tained by the soil for a period of not less than 48 hours
with no additional settlement taking place, in order that
such desired bearing capacity may be used. Subsoil con-
ditions shalI be examined at the expense of the owner,
when deemed necessary by the building official.

shall be built upon natural solid ground. Where solid nat-
ural ground does not occur at the foundation depth, such
foundations shall be extended down to natural solid
ground or piles shall be used. Foundations may be built
upon mechanically compacted earth or fill material sub-
ject to approval by the building official upon submittal of
evidence that the proposed load will be adequately sup-
ported.

./1804.2.4 Differential settlement. Where footings are
supported by soils of widely different bearing capacity, the
allowable bearing values of the more yielding soil shall be
reduced or special provisions shall be made in the design
to prevent serious differential settlements.
./1804.2.5 Shifting or moving soils. When it is definitely
known the top or subsoils are of a shifting or moving char-
acter, all footings shall be carried to a sufficient depth to
insure stability. The excavation around piers shall be back-
filled with soils or materials which are not subject to such
expansion or contraction.
