Critical 2025 US 1 Level of Service Study

was also on the Commission agenda Sep 10. This study is used by Monroe County and the municipal governments to determine if there is sufficient capacity available on U.S. One to accommodate all existing and approved development.

Failing Grade: When the study has a failing grade, below C, for the entire U.S. One, the County Commission has consistently rejected the study (2019, 2023) because most development, other than single family homes, would be curtailed or traffic impacts mitigated in most areas of the Keys.     Passing Grade: When there is a passing grade of C or above the Commission approves the study. The 2025 study had a passing grade and was approved. There was significant public comment critical of the annual report. The Average Daily Trips documented for 2025 were the lowest number of daily trips recorded for the last 15 years.  Few found the statistics believable.   The studies must be done during the peak season - before the end of March.  The 2025 study was delayed and completed later than “peak season” as required.

Islamorada Traffic according to the Study: There were three traffic segments out of 24 segments in the Keys that had a failing grade in 2025, all the failing grades were in Islamorada: Lower Matecumbe, Upper Matecumbe, Windley Key.  Plantation Key had a passing score because construction delays (FKAA Water Pipeline project) are ignored.  But it didn’t mean the congestion didn’t impact drivers! Islamorada Standards: In Marathon and unincorporated Monroe County, if a segment falls below a Grade C, construction in the segment can only be approved with costly mitigation, except for single family homes. In Islamorada, the determining traffic is measured on an overall countywide basis not dependent on individual US 1 segments. Therefore building permits can continue to be issued in spite of three segments in Islamorada falling below a Grade C.

County Commission Reverses themselves on 4 Laning US 1.

The County Commission voted 4-1 last February directing staff to prepare a Comprehensive Plan amendment to give FDOT the right to decide what areas of US 1 in Unincorporated Monroe County, including the 18-mile stretch, should be 4-laned.  Last month the Planning Commission voted to recommend to the County Commission that they deny the change they requested.  

At a meeting with county officials, FDOT District 6 Secretary Stacy Miller indicated that before FDOT would take step 1, a feasibility study, they would require the right to decide on the widening issue for all areas of the Keys, including Islamorada. Four lanes through Islamorada would be especially devastating in business areas.

The members of the County Commission were inundated with emails and phone calls leading up to their Wed Sep 10 meeting.  The meeting room was full of residents and business owners against 4-laning.  Residents and business owners were united against giving up local control regarding such a critical issue.

One by one, the members of the commission who had requested the change, informed the public that they would now be voting against their requested amendment.

Vice Mayor Don Horton spoke against the amendment on behalf of the Islamorada Council. He suggested that instead of 4-laning, FDOT should provide the funding, needed for widening, to Islamorada so the Village could reduce congestion by providing a bus or trolley system within Islamorada for residents and visitors.

FDOT has been providing Islamorada funding through a “Transit Development Grant” which has been paying 50% of the $553,330 of the Village’s contract with Freebee to provide an on demand rideshare service.  Some would argue that the Freebee program, while beneficial to riders, is not decreasing congestion in Islamorada.

DRAFT 2023 TRAVEL STUDY RELEASED

U.S. 1 through all of Monroe County was rated a Level of Service D (LOS D).  Surprise… Islamorada traffic is the worst of all.
