Review roadway and traffic modification regulations

189, F.S., Municipal and County Speed Zones states that the maximum speed within any municipality is 30 miles per hour. With respect to residential districts, a municipality may set a maximum speed limit of 20 or 25 miles per hour on local streets and highways after an investigation determines that such a limit is reasonable. A municipality may set speed zones altering the speed limit, both as to maximum, not to exceed 60 miles per hour, and minimum, after investigation determines such a change is reasonable and in conformity to criteria promulgated by the Florida Department of Transportation, except that no changes shall be made on state highways or connecting links or extensions thereof, which shall be changed only by the Florida Department of Transportation. MIAMI-DADE COUNTY CODE Speed Zone Limits Speed zones throughout Miami-Dade County are governed by Section 30-4 - Establishment of county speed zones; enforcement and penalties. It states that all speed zones on County and municipal streets, roads and highways shall be set in accordance with the provisions of

189, Florida Statutes, as such may be amended from time to time. Traffic Flow Modifications Miami-Dade County has exclusive jurisdiction over traffic control within a municipality. As such, the municipal jurisdictions are required to submit a traffic study to the Miami-Dade County Transportation and Public works Department for their review and approval. The study must support the proposed traffic flow modification(s)/street closure(s) and show that County and State roadways would not be adversely impacted as a result of such traffic flow modification(s)/street closure(s). Miami-Dade County developed a uniform set of guidelines or warrants to be followed by local municipalities, the County and the State for implementing neighborhood and localized area traffic control; and developed a standardized set of procedures to be followed by local applicants desiring enhanced neighborhood traffic control. These guidelines are detailed in the Miami-Dade County Traffic Flow Modification(s) / Street Closure(s) Procedure which was last revised in 2009 (see Exhibit B), and must be followed by the Village for all traffic calming measures including but not limited to those listed in the Traffic Engineering Function Agreement. Among a number of steps, the procedure includes a step that requires concurrence from a specified number of affected residents and/or property owners as follows: • Traffic Circles: Requires 100% concurrence of affected residents and/or property owners from four (4) corners adjacent to the proposed circles. This may be extended to the full block should a larger representation be desired by the District Commissioner. • Traffic Flow Modifications other than Traffic Circles: Requires concurrence of two- thirds (2/3) of the affected residents and/or property owners, who elected to vote (ballots received). Non-voters are not counted (ballots not returned). • Municipal Jurisdictions: In lieu of concurrence from the affected residents and/or property owners, a municipality may pass a resolution after a public hearing requesting the Miami-Dade Transportation and Public Works Department consider the proposed traffic flow modification(s)/street closure(s).

Harris, Inc. to conduct a Street Closure/Traffic Flow Modification Study that was completed in July 1996. The primary objectives of the study were to: • Evaluate and recommend traffic control alternatives to street closures; • Develop a uniform set of guidelines or warrants to be followed by local municipalities, the County and the State for implementing neighborhood and localized area traffic control; and • Develop a standardized set of procedures to be followed by local applicants desiring enhanced neighborhood traffic control. A Steering Committee was assembled and periodically convened to meet with the Consultant to provide input throughout the study process. The Steering Committee consisted of representatives from the Florida Department of Transportation, Miami-Dade County and local municipalities; some of whom had previous experience with citizen requests for street closures. The draft report was developed as a series of Technical Memorandums that were reviewed by the steering committee and later compiled to form the final report. The Steering Committee developed standardized procedures and guidelines for use by the public, local officials, or other private sector interests requesting traffic flow modifications that may affect local neighborhoods as well as other roadway traffic patterns. The intent of these procedures was to provide Miami-Dade County and municipalities with a uniform approach to facilitate government action in response to requests to restrict local traffic access via street closures, other physical modifications or traffic calming alternatives. These proposed procedures were also intended to ensure that such issues are given appropriate study and timely response, and that the full range of traffic and community impacts is considered. The procedures addressed traffic issues in an incremental fashion with the least restrictive measures applicable to a particular situation tested first, then monitored and supplemented, modified or replaced with more stringent measures, if necessary. When non-traffic issues enter into the decision process, the procedures weigh both the traffic and non-traffic implications of a street closure or traffic flow modification. Although each citizen request is unique, the process applies equally to any residential traffic control situation and provides government officials with an objective tool to address neighborhood traffic control issues. On May 20, 1997, the Miami-Dade County Board of County Commissioners approved Resolution No. R-545-97 authorizing an eighteen-month pilot program to implement and evaluate traffic flow modification/street closure study recommendations. A subsequent extension was granted under Resolution No. R-66-00 on January 25, 2000. Since then, County staff has been using this procedure. It has been enhanced over the span of the last twelve years and updated and revised to appropriately address the needs of residents of Miami-Dade County in order to improve their safety as well as their livability standards.

Should the request be initiated through or by a municipality or the Florida Department of Transportation, then these agencies, at their option, may conduct traffic studies utilizing their staff or a traffic consultant. 1.3 PWD will make the determination of whether the location(s) falls within unincorporated Miami-Dade County or a municipality, and coordinate the review with the respective municipality. 1.4 PWD will make the determination of whether the review from various affected entities, such as Police, Fire, etc., is required. If review is not required, proceed to Step 1.6. 1.5 Should review be required, PWD will request the affected entities, including but not limited to, Police, Fire, respective municipality, etc., to review the request and provide comments. If review by any of the entities results in a denial as a result of concerns which cannot be resolved, or if the proposed traffic flow modification(s)/street closure(s) does not meet all criteria outlined under this process or applicable County and State laws, then the application will be denied. 1.6. PWD will make the determination if concurrence from the required affected residents and/or property owners is required. If concurrence is not required, proceed to Step 1.8. Required Concurrence: Traffic Circles: Requires 100% concurrence of affected residents and/or property owners from four (4) corners adjacent to the proposed circles. This may be extended to the full block should a larger representation be desired by the District Commissioner. Traffic Flow Modifications other than Traffic Circles: Requires concurrence of two- thirds (2/3) of the affected residents and/or property owners, who elected to vote (ballots received). Non-voters are not counted (ballots not returned). Municipal Jurisdictions: In lieu of concurrence from the affected residents and/ or property owners, a municipality may pass a resolution after a public hearing requesting PWD to consider the proposed traffic flow modification(s)/street closure(s). 1.7 PWD will mail out ballots to obtain concurrence from the affected residents and/or property owners. Should the required concurrence be secured, PWD will proceed to the next step.

Applicant Engages a Traffic Consultant to Perform a Traffic Study In the event that the action taken by PWD in accordance with Phase 1 procedures is unacceptable to the municipal jurisdiction, or the residents and/or property owners, they have the option of engaging a traffic consultant, at their cost, to conduct an independent traffic study. Should the request be initiated through or by a municipality or the Florida Department of Transportation, then these agencies, at their option, may conduct traffic studies utilizing their staff or a traffic consultant. 2.1.a If the location falls within unincorporated Miami-Dade County, this study is coordinated by PWD. 2.1.b If the location falls within a municipality, the study is coordinated by the municipality and reviewed by the PWD. 2.2. Conduct Pre-implementation Traffic Study The traffic consultant hired by the applicants shall perform a pre-implementation traffic study. This study shall identify and confirm the applicant’s concerns (i.e., traffic intrusion, excessive traffic volume, speeding, traffic accidents, etc.) and determine if the collected traffic data meets PWD traffic calming criteria. On a case-by-case basis, PWD, Traffic Engineering Division, may require the following data depending on the type and complexity of the concerns: 2.2.a License Plate Survey: If the reason for the request is due to traffic intrusions, this survey will be required for confirmation of cut-through traffic. Sampling during the morning and afternoon peak hour periods will be considered adequate. 2.2.b Average Daily Traffic: If the reason for the request is due to an excessive amount of traffic in the area, a sampling of twenty-four (24) will be acceptable, and forty eight (48), or seventy-two (72) hour counts will be preferred. 2.2.c Speed Studies: If the reason for the request is due to speeding, then speed studies are required to confirm vehicular speed. A speeding problem can be verified when the 85th percentile speed of all vehicles is at least 10 mph greater than the posted speed limit. A non-peak hour daytime minimum sampling of 100 vehicles will be considered acceptable. A twenty-four (24) hour speed study utilizing traditional dual hoses will be preferred. 2.2.d Traffic Accident History: If the reason for the request is due to traffic accidents, then traffic accident reports for the last three (3) years are reviewed to confirm accident history. The proposed traffic calming measure shall mitigate significant crashes. 2.2.e Other data and/or studies as needed. Traffic Flow Modification(s)/Street Closure(s) Procedure Page 18 \\miamidade\nas2\PWWM2\TE-OPERATIONS\00 Standards and references\Traffic Flow Modification-Street Closure_Original\TRAFFIC FLOW MODIFICATION(S) STREET CLOSURE(S) PROCEDURE_2009.doc PWD, on a case-by-case basis, may require additional traffic data or studies if needed. 2.2.f. If the pre-implementation study reveals that the traffic data does not support PWD Policy for Traffic Calming Measures (Appendices I, II and III) then a final decision of denial is rendered and the process ceases. PWD will notify the applicant of the denial. 2.2.g If the pre-implementation study confirms that a problem exists and the traffic data meets PWD Policy for Traffic Calming Measures (Appendices I, II and III), the applicant may proceed to the next step. 2.3. Identify Traffic Calming Alternatives The consultant shall adopt an area-wide systematic approach to the development of traffic calming alternatives. This approach must work within the overall framework of the existing roadway classification system and encourage community participation. There are three (3) levels of traffic calming ranging from I to III to distinguish those least restrictive (passive) traffic control measures from those that are most restrictive (active). Among the categories, there could be many design variations unique to each device. Ideally, the least restrictive measures to address traffic concerns should be employed first, followed by more active and physical traffic calming devices. This incremental approach allows a cost-effective opportunity to identify the real traffic problem, if any, and better evaluate the impact of more restrictive measures. Keeping the above-staged approach in mind and a handful of traffic calming alternatives available for use on local roads, a typical request for a traffic flow modification(s)/street closure(s) might proceed accordingly: 2.3.a The traffic consultant will assess the community’s needs. 2.3.b The consultant will generate staged alternative traffic calming plans, including design plans for temporary and permanent traffic calming measures, for approval by PWD, as well as cost estimates. 2.3.b.1 PWD will implement the lowest level of (Level I through Level III) traffic control measures on a temporary basis that, in the consultant’s opinion, will satisfy the applicant’s concerns. 2.3.b.2 Allow traffic to stabilize and reevaluate traffic patterns after six (6) months. 2.3.b.3 If Level I measures is selected and its impacts are unacceptable, then proceed to Level II and reevaluate more restrictive traffic calming alternatives. If Level II impacts are unacceptable, then proceed to Level III and reevaluate. 2.3.b.4 If the impacts of Level I, II or III measure, so selected are acceptable, PWD Traffic Flow Modification(s)/Street Closure(s) Procedure Page 19 \\miamidade\nas2\PWWM2\TE-OPERATIONS\00 Standards and references\Traffic Flow Modification-Street Closure_Original\TRAFFIC FLOW MODIFICATION(S) STREET CLOSURE(S) PROCEDURE_2009.doc will implement permanent traffic control measures, as funding and contracts are identified. Traffic Flow Modification(s)/Street Closure(s) Procedure Page 20 \\miamidade\nas2\PWWM2\TE-OPERATIONS\00 Standards and references\Traffic Flow Modification-Street Closure_Original\TRAFFIC FLOW MODIFICATION(S) STREET CLOSURE(S) PROCEDURE_2009.doc The following categories of traffic calming alternatives are most effective when used in combination with each other: LEVELS OF TRAFFIC CALMING LEVEL I LEVEL II LEVEL III Education Neighborhood Speed Watch Program Law Enforcement Movement Restrictions One-Way Streets Multi-Way Stop Control Textured Pavement Gateway Treatments Border Landscaping Treatment Chokers Roundabouts Traffic Circle Speed Humps Raised Median through Intersections (Right Turn Only) Mid-block Raised Islands/Medians Semi Diverter Diagonal Diverter Street Closure Speed Humps The consultant shall also prepare a cost-estimate for the traffic calming alternatives identified above and proceed to the next step for a pre-implementation study. 2.4. Perform Pre-implementation Study to Determine the Potential Impact of Traffic Calming Measures on Roadways within and outside of the Study Area The consultant shall conduct a pre-implementation study to determine the potential impact of the proposed traffic calming devices/street closure(s), within and outside of the study area. Depending on the type, complexity and requirements of the area in question, PWD may, on a case-by-case basis, require analysis per Step 2.4.d and 2.4.e, which must conform to the following criterion: 2.4.a Volume Criteria: 2.4.a.1 Future traffic volumes due to traffic diversion on any of the Residential Local Streets may not exceed 1,500 vehicles per day (150 vehicles per hour (VPH) during the peak hours) if a traffic flow modification(s)/street closure is implemented. The threshold values define those limits when a local residential street begins to lose its livability and are used for analysis purposes only. They do not guarantee that the traffic flow modification(s) or closure(s) will be approved. 2.4.a.2 Future traffic volumes due to traffic diversion on any of the Residential Collector Streets may not exceed 3,000 vehicles per day (300 VPH during the peak hours) if a traffic flow modification(s)/street closure(s) is implemented. These threshold values define those limits when a residential collector street begins to lose its livability and are used for analysis purposes only. They do not guarantee that the traffic flow modification(s) or closure(s) will be approved. Traffic Flow Modification(s)/Street Closure(s) Procedure Page 21 \\miamidade\nas2\PWWM2\TE-OPERATIONS\00 Standards and references\Traffic Flow Modification-Street Closure_Original\TRAFFIC FLOW MODIFICATION(S) STREET CLOSURE(S) PROCEDURE_2009.doc 2.4.b Level of Service (LOS) Criteria: 2.4.b.l Future overall intersection Level of Service (LOS) must not exceed LOS “D” or if operating at LOS "E" must not degrade to LOS "F". 2.4.b.2 The same criterion applies for an individual intersection approach within the critical intersection approach. 2.4.b.3 If intersection or approach is already at LOS “F”, then diverted traffic volumes must not be more than 10% of the existing traffic volumes without diversion. 2.4.c Determine Affected Area: The affected area may include, but is not limited to, those properties where normal travel routes, to and from the affected area, are to be altered by the traffic flow modification(s)/street closure(s) and/or properties that are significantly impacted by the diverted traffic. 2.4.c.1 If the request for traffic flow modification(s)/street closure(s) falls within unincorporated Miami-Dade County, PWD will establish affected area boundaries on a case-by-case basis and obtain concurrence from FDOT if their facilities are impacted. 2.4.c.2 If the request for traffic flow modification(s)/street closure(s) falls within a municipality, both the City’s, and County’s staff will determine the boundaries of the affected area on a case-by-case basis, and obtain concurrence from the Florida Department of Transportation (FDOT), if their facilities are impacted. 2.4.d Conduct Traffic Analysis within the Study Area: For critical locations, if any, provide projection of the expected diverted traffic within the study area. This will require the following steps: 2.4.d.1 Peak-hour turning movement counts (TMC). 2.4.d.2 Twenty-four (24), forty eight (48), or seventy-two (72), hour counts on those streets that are proposed to be closed or modified. 2.4.d.3 Twenty-four (24), forty eight (48), or seventy-two (72) hour counts on those streets that may be impacted by proposed traffic flow modification(s)/street closure(s). 2.4.d.4 LOS analysis at critical locations that will be affected by redistributed traffic. 2.4.d.5 A schematic diagram for both morning and afternoon peak hours showing existing and redistributed traffic and Average Daily Traffic (ADT). Traffic Flow Modification(s)/Street Closure(s) Procedure Page 22 \\miamidade\nas2\PWWM2\TE-OPERATIONS\00 Standards and references\Traffic Flow Modification-Street Closure_Original\TRAFFIC FLOW MODIFICATION(S) STREET CLOSURE(S) PROCEDURE_2009.doc 2.4.e Conduct Traffic Analysis outside the Study Area Projection of the expected diverted traffic at critical intersections, if any, adjacent to and surrounding the affected area. Particular attention shall be paid to the impacts on the State Highway System and County roadways, including: 2.4.e.1 Peak-hour TMC. 2.4.e.2 Queuing analysis and storage requirements at signalized intersections. 2.4.e.3 LOS analysis at critical signalized and un-signalized existing intersections. 2.4.e.4 A schematic diagram showing the results of the TMC and ADT analyses for critical locations. 2.4.e.5 Phasing modification requirements at existing signalized intersection. 2.4.e.6 A detailed evaluation of the impacts caused by the traffic flow modification(s)/street closure(s) on emergency vehicle response times and fire hydrant accessibility, as well as other services such as mail delivery, school bus routing, transit service, trash pick-up, etc. Each individual case will dictate which of the above items are required, depending on the complexity and requirements of the study area. 2.4.f The Report: The consultant will document the study in the form of a report. PWD will require the following items as part of this report: • A drawing that shows the exact location of existing and proposed traffic flow modification(s)/street closure(s). • Boundary of the affected area. • Critical intersection geometries. • Analysis of the critical intersections and roadway links per

4.d and 2.4.e. • Comparison of before and after LOS. The consultant will indicate the optimum traffic calming measure from each of Levels I, II and III, which adequately satisfies the applicant’s concern. The Level I measure generally should be implemented first. However, depending on the severity of the case at hand and/or unusual circumstances a higher level of measures can be implemented. If the results are not satisfactory, then the next level measure will be implemented until Level III is reached.
