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. 9.2 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. 88
