ANALYSIS
BACKGROUND
On January 17, 2016, the Mayor's Blue Ribbon Panel on Sea Level Rise discussed the
attached Ordinance amendment and recommended that the City Commission refer it to the
Land Use and Development Committee and Planning Board. Commissioners John Elizabeth
Aleman and Joy Malakoff are the sponsors of the item.

the Land Use and Development Committee (Item C4 E). The amendment was simultaneously

the sponsors of the item.
On February 15, 2017, the Land Use and Development Committee recommended that the
Planning Board transmit the ordinance to the City Commission with a favorable
recommendation.
PLANNING ANALYSIS
Several innovative roofing systems are being developed to improve the sustainability of
buildings. These include solar roofs, which allow for the generation of electricity; blue roofs,
which improve stormwater retention and treatment; white/cool roofs, which reflect sunlight and
reduce the heat island effect; green roofs, which provide vegetation and irrigation to reduce heat
island effect, and improve stormwater retention; and rooftop farming systems which for food
growth.

The proposed ordinance amendment allows for the use of sustainable roofing systems for roof
replacement. Additionally, the proposed ordinance expands the use of energy efficient roofing
systems, such as standing seam metal, and prohibits the use of asphalt shingles which typically
absorb heat and increase the urban heat island effect and surrounding temperatures.
PLANNING BOARD REVIEW
On April 25, 2017, the Planning Board transmitted the proposed Land Development
Amendment to the City Commission, with a favorable recommendation.
UPDATE
The subject ordinance was approved at First Reading on May 17, 2017, with no changes.
