VILLAGE OF KEY BISCAYNE UNDERGROUNDING OF UTILITIES — MASTER PLAN
West of Crandon Boulevard, Harbor Drive circulates as the westernmost
north-south thoroughfare connecting to Mashta Drive on the south. Mashta
Drive is southernmost east-west thoroughfare and the only entrance to
Mashta Island. From Harbor Drive to Mashta Drive, Fernwood Road runs
parallel to Crandon Boulevard. A series of traffic calming circles and raised
intersections are present throughout the residential network.
East of Crandon Boulevard a variety of local roads provides access to the
multi-family residences and hotels. The rest of the Village is comprised of
local residential, commercial, or mixed-use roads.

Traffic Conditions Prior to Start to Work
Traffic Volume Data
Traffic counts, road capacities, and Levels of Service (LOS) for 11 major
road links are presented in the counts, collected on at least two weekdays
in either April or March of 2015. This was the most recent traffic data
available for the Village. A location map of the 11 different roadway link
locations is provided at right. The data contained the peak season 2015
traffic count data presented in a series of tables per location. The highest
volume identified was used for analysis for three scenarios: daily, AM peak
hour, and PM peak hour. After careful review, some abnormalities were
found at two of the links in comparison with adjacent locations (location
6 and 7). Therefore, as construction is expected to start in 2020, more
updated traffic data is recommended to be obtained.
Tables 1, 2, and 3 on the following pages contain traffic volumes, roadway
classes, capacities (adjusted as per FDOT criteria in the 2013 Quality/Level
of Service Handbook), volume to capacity ratios, and LOS for the 11 links in
each of the three scenarios.
The overall trend on the island is the two-lane arterial roadways tend to
have LOS C or better. Rickenbacker Causeway south of the toll has LOS B
until just north of Harbor Drive where the roadway transitions into the
developed region of the island and changes from Rickenbacker Causeway
(SR 913) to Crandon Boulevard. Additionally, directionality is well-defined,
with traffic generally heading onto the island in the AM peak hour and off
the island in the PM peak hour.
