Subject: Amendments on the Floor of the two heat island ordinances
The two heat island ordinances were amended on the floor last night. As you know, they are going
to commission on 9/24. Do we need to do anything to include the amendments as a substitution
item for the 9/24 commission? Do you want me to email the amendments in writing?

ORDINANCE NO (X)
AN ORDINANCE OF THE CITY OF MIAMI COMMISSION AMENDING ARTICLE 9
OF ORDINANCE NO. 11000, THE ZONING CODE OF THE CITY OF MIAMI,
FLORIDA, TO CREATE SECTION 952 ENTITLED "HEAT ISLAND EFFECT — NON
ROOF" TO ADD SECTIONS TO PROVIDE FOR ENVIRONMENTALLY
RESPONSIBLE METHODS FOR COOLING AND SHADING OF HARDSCAPES IN
CITY OF MIAMI, CONTAINING A SEVERABILITY CLAUSE AND PROVIDING FOR
AN EFFECTIVE DATE.
WHEREAS, The City of Miami is committed to reducing elevated temperatures and associated
air-quality issues stemming from urban heat island effects; and
WHEREAS, during the past eight (8) years, the City of Miami ("City") has launched a
comprehensive and aggressive environmental program to clean streets, waterways, brownfields,
storm drains, and to improve air and water quality; and
WHEREAS, the City Commission has adopted the recommendations of MiPlan, the City of
Miami Climate Action Plan, which promotes various methods to achieve reduction in energy
consumption which is adversely affected by elevated temperatures in the urban -core; and
WHEREAS, elevated temperatures from heat island effects in urban areas result in increased
energy consumption for cooling; increased greenhouse gas emission associated with building and
vehicle usage; and deterioration in air quality; and
WHEREAS, hardscape management methods, such as tree planting, shading, and use of
reflective paving materials, will contribute to decreasing the urban heat island effect, which can
reduce the energy consumption of City buildings;
NOW THEREFORE, BE IT ORDAINED BY THE COMMISSION OF THE CITY OF
MIAMI:
Section 1. The recitals and findings in the Preamble to this ordinance are adopted by reference
and incorporated as if fully set forth in this Section.

particulars:
Article 9
General and Supplementary Reg lations
Section 952
HEAT ISLAND EFFECT — ]"40N -ROOF
r
952.1 Intent
The requirements of this ordinance are intended to reduce the heat island effect from
hardscapes in the City of Miami and to consequently reduce energy consumption and bills for
buildings within the City.
952.2 Definitions
Hardscape means the nonliving portions of a building's landscaping, such as roads,
sidewalks, courtyards and parking lots
Heat island effect is an elevated temperature over an urban area when compared to rural
areas, typically caused by the increased presence of dark, heat absorbing materials, such as
asphalt and dark roofs, in urban areas.
Solar reflectance is the fraction of solar energy reflected by a material.
Pervious Pavement System is a porous surface system with a stabilized base that allows water
from precipitation and other sources to pass directly through, thereby reducing the runoff
from a site, allowing groundwater recharge, and naturally cooling the surface through
evaporation of water from pavement voids or from beneath.
952.3 Applicability
The provisions of this ordinance are applicable to newly constructed building and to
replacement of greater than 50% of site hardscape after the effective date of this
ordinance and located in the City of Miami. All replacement of existing hardscape shall
be reviewed by the Zoning Department for compliance with this ordinance.
952.3 Solar reflectance
Solar reflectance shall be determined as follows:
(a) For roofing materials, all roof exterior surfaces and building materials used to
comply with Section 952.4 shall have a minimum solar reflectance as specified in
Sections 952.4 when (i) tested in accordance with ASTM E903 or ASTM E1918,
(ii) tested with a portable reflectometer at near ambient conditions, (iii) labeled by
the Cool Roof Rating Council, or (iv) labeled as an Energy Star qualified roof
product. Any product that has been rated by the Cool Roof Rating Council or by
Energy Star shall display a label verifying the rating of, the product.
(b) For paving materials, all paving materials used to comply with Section 952.4 shall
have a minimum solar reflectance as specified in Sections 952.4 when (i) tested in
accordance with ASTM E903 or ASTM E1918, (ii) tested with a portable
reflectometer at near ambient conditions, or (iii) default values of solar reflectance
for listed materials may be used as follows:
TABLE INSET:
Material
Solar Reflectance
Typical new gray concrete
0.35
Typical weathered gray concrete
0.20
Typical new white concrete
0.70
Typical weathered white concrete
0.40
New asphalt
0.05
Weathered asphalt
0.10
952.4 Requirements
Sites with new construction shall be required to comply with the following:
(a) Provide any combination of the following strategies for fifty percent (50%) of the site
hardscape:
(i) Shade from solar panels or roofing materials with a solar reflectance of at
least 0.30
(ii) Shade from trees within five (5) years of occupancy
(iii)Paving materials with a solar reflectance of at least 0.30
(iv)Pervious pavement system
OR
(b) Place a minimum of fifty -percent (50%) of parking spaces under cover (defined as
underground, under deck, under roof, or under building). Any roof used to shade or
cover parking must have a solar reflectance of at least 0.30.
Section 3. All ordinances or parts of ordinances that are inconsistent or in conflict with the
provisions of this Ordinance are repealed.
