SUBIECT: Below Grade Floor Area
FIRST READING
AN ORDINANCE OF THE MAYOR AND CITY COMMISSION OF THE
CITY OF MIAMI BEACH, FLORIDA' AMENDING THE CODE OF THE
CITY OF MIAMI BEAGH, FLORIDA, BY AMENDING CHAPTER 114,.,GENERAL PROVISIONS,'' BY AMENDING THE DEFINITION OF
FLOOR AREA; PROVIDING FOR REPEALER, SEVERABILIry,
GODIFICATION AND AN EFFECTIVE DATE.
ADMINISTRATION RECOMM EN DATION
The Administration recommends that the City Commission approve the Ordinance at
First Reading and schedule a Second Reading Public Hearing for June 11,2014.
BACKGROUND
On December 11,2013, the City Commission referred the item to the Planning Board.
Section 114-1 of the Land Development Regulations of the City Code currently defines
floor area as the sum of the gross horizontal areas of the floors of a building or buildings,
measured from the exterior faces of exterior walls or from the exterior face of an
architectural projection, from the centerline of walls separating two attached buildings.
This is an important concept, as it is then used to determine floor area ratio (FAR), which
governs how much floor area is permitted for a development, and which controls how
much mass and bulk proposed new buildings may contain.
The Code's definition for floor area of a building contains certain specified exemptions,
such as enclosed garbage rooms, mechanical equipment rooms located on the roof,
water tanks or cooling towers, uncovered steps, attic spaces, terraces, breezeways, or
open porches, exterior unenclosed private balconies and required parking areas.
Another exemption from the definition in this section is for "floor area located below
grade." This means that if an area is completely underground, it does not count towards
floor area. This section continues, "if the ceiling is above grade, one-half of the floor
area that is below grade shall be included in the floor area ratio calculation."
ANALYSIS
Several recently approved projects have been permitted where the first floor slab is only
a few inches below grade elevation, which is defined as the city sidewalk elevation at the
centerline of the property. The code currently allows Yz of lhe entire floor area to be
exempted from the floor area ratio (F.A.R.) calculations regardless of how far below
grade the floor slab is located. The result is that although 99% of the mass of the first
530
Commission Memorandum

floor may be above grade, only 50% is counted towards the F.A.R. of the building.
The current language of the Code does not clearly define how far below grade a floor
must be to qualify for the 'one-half' exception. Fu(hermore, the full exception does not
clearly state the floor must be completely below grade to exclude the entire floor area,
which is the intent of the exception.
ln light of the significant challenges that the City faces regarding sea level rise, flooding
and water retention, staff has concluded that it no longer makes sense to encourage or
incentivize the construction of floor area below grade. Therefore, the Administration
recommends that the proposed ordinance eliminate any benefit or bonus for those
portions of a structure proposed to be located partially below grade.
PLANNING BOARD REVIEW
On March 25, 2014, the Planning Board recommended approval of the subject
Ordinance by a vote of 5 to 0.
The Board also discussed the possibility of allowing floors located partially below grade
to receive some form of credit, whereby in order to qualify for a 5oo/o discount of floor
area, the finished floor must be located at least four feet (4') below grade. However the
Board adopted the Ordinance as drafted without the inclusion of this 50% discount.
FISCAL IMPACT
ln accordance with Charter Section 5.02, which requires that the "City of Miami Beach
shall consider the long term economic impact (at least 5 years) of proposed legislative
actions," this shall confirm that the City Administration evaluated the long term economic
impact (at least 5 years) of this proposed legislative action. The proposed Ordinance is
not expected to have any tangible fiscal impact.
SUMMARY
When a first floor slab is located below grade, the code currently allows % of the entire
floor area to be exempted from the floor area ratio (F.A.R.) calculations regardless of
how far below grade the floor slab is located. This is problematic considering the
significant challenges that the City faces regarding sea level rise because it actually
encourages retail development on the ground floor of buildings to be placed a few inches
below grade in order to gain this "FAR bonus". The proposed Ordinance would eliminate
any benefit or bonus for those portions of a structure proposed to be located partially
below grade.
CONCLUSION
The Administration recommends that the City Commission approve the Ordinance at
First ff,pading and schedule a Second Reading Public Hearing for June 11,2014.,-d*/
