Summary of Findings: Infrastructure
»The City has a 30 year sea level change (SLC)
planning horizon for stormwater.
»Jan. 2020: The current water table in adjacent
Collins Canal is 1.7 feet.
»Sept. 2015: King Tide high water elevation at the
Collins Canal was 2.1 feet.
»Sept. 2019: Maximum water elevation at the
Collins Canal was 2.08 feet.
»Existing neighborhood roadway elevations vary
from lower than 2 feet to 3.7 feet.
»Lower than 2 feet:
»Michigan Ave (17th St –Collins Canal)
»Jefferson Ave (18th St –Collins Canal)
»19th St (Jefferson Ave –Meridian Ave)

Summary of Findings: Infrastructure
»The number of ditch bottom and curb inlets is
insufficient, based on the documented nuisance
flooding that occurs during typical summer rainfall
events.
»Within Palm View, there are 8 foot wide green
pervious areas on both sides of the roads.
»Along 19th St, the green strip is 2.5 feet wide.
»Raised D-curbs separate the green pervious areas
from the adjacent roadway.
»These curbs block the path of street stormwater
runoff to the pervious areas, preventing them from
properly functioning as drainage swales.
»The neighborhood’s stormwater system is an
independent gravity-based stormwater system.
»2 outfalls flow into Collins Canal on the north end
of the neighborhood.
»Currently, there are no floodgates on the inlets.
»There will be impacts related to future sea level
rise, specifically to the Collins Canal, with a
projected sea level rise of 2.58 feet to 6.75 feet by
2060.1

What is a Resiliency Zone/District?
“A special improvement district, precinct, neighborhood, or
corridor designated in official planning documents for
comprehensive risk management
and upgrading so that it is more resilient in the face of a variety of
predictable and unpredictable extremes.”
–CERES2

2. CERES is a United States-based organization that advocates for the adoption of sustainable business practices and solutions to build a healthy global economy. CERES Insurance Program is working with leaders and investors in the insurance industry to set new standards and expectations that can enable insurers to plan for emerging climate risks while moving companies and individuals toward low-carbon activities
»A relatively new planning concept based upon
the traditional principles of establishing zoning
overlays or “districts”where criteria incorporate
climate adaptation regulations,processes,and
criteria.
»To date, very few jurisdictions have
created such resiliency districts.
»Miami Beach has an opportunity to set
the standard.
»Design Standards for Resilient Historic Structures

Design Standards for Resilient Historic Structures
»Elevated entryways in front or back
»Sunken gardens or shared retention
»Adaptation -elevation, materials, aesthetics
»Adaptations in the back versus the front
»Mitigate transitions in height by the use of planter
walls
»Maintain existing historic hardscape features such as
planter walls, fences, and gates
»If building elevated, maintain a piazza entry at ground
level
»Historic material and details kept at the pedestrian
level
»Consider the effects of sister properties within their
context
»Significant elevation changes should create the
appearance of an additional floor that proportionally
relates to the floors above and fenestration patterns
on the streetscape
»Elevated mechanical systems
»Implementation or administrative provisions of zoning
code should include Implementation matrix should
include strategies that include historic resources in the
context of hazards or creation of an “annex,” similar to
how all other sectors are addressed

Summary of Findings: Land Development Requirements
»Palm View consists of a mix of single-family and
multi-family land uses.
»Single-family residential development accounts for
the majority of the total land area of the
neighborhood.
»This is consistent with the historic development
pattern in the neighborhood’s core.
»Multi-family developments are located along the
edges of the neighborhood.
»The neighborhood is in close proximity (within a
10-minute walk) to commercial areas.

Summary of Findings: Historic Preservation
»10 different architectural styles are present within
the neighborhood.
»Mediterranean Revival is the most predominant
architectural style within the neighborhood.
»Period of Significance is not established
»Architectural styles from 1920s –1960s
»Of the 74 structures in the historic district,
64 were deemed contributing.3
»The Carl Fisher era of design and construction is
the neighborhood’s most significant time period.4
»The structures within the Palm View neighborhood
that have the highest level of architectural
detailing and artistic value are those associated
with the Carl Fisher era of design and construction.
»When reviewed in the context of the Carl Fisher
era of design and construction, many properties
within the existing historic district boundaries do
not meet the designation criteria.

Summary of Findings: Property Sales and Valuation
»Market analysis areas are smaller within the City
of Miami Beach than in western Miami-Dade
County.
»Single-family residential lots in the neighborhood
have an estimated land value of approximately
$1,000,000.
»The neighborhood’s land value is much higher than
the relative land values of the two Miami Beach
neighborhoods used to compare sales data (Ocean
Beach Subdivision and the Fairgreen/Orchard
Subdivision).
»Palm View’s assessed market value has remained
relatively stable over the last 3 years.
»Some residents expressed concerns of low sales
volume and property values during the
neighborhood outreach process.
