City of Dade City AGENDA MEMO TO: THRU: FROM: The Honorable Camille Hernandez, Mayor and Members of the City Commission William C. Poe, Jr., City Manager Michael Sherman, AICP, Community Development Director DATE: 11 October 2016 SUBJ: Traffic Calming Introduction work session BACKGROUND: Over the past couple of years City staff, the City Commission, city residents and our neighborhood plans, have discussed the importance of increased safety and walk-ability of our local roads and neighborhood streets. One way that this can be achieved is through implementation of a local Traffic Calming program. Traffic calming is defined by the Institute of Transportation Engineers (ITE) as the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behavior and improve conditions for nonmotorized street users. Goals of traffic calming include: increasing the quality of life; incorporating the preferences city residents and others using the area (e.g., working, playing, residing) along the street(s), or at intersection(s); creating safe and attractive streets; helping to reduce the negative effects of motor vehicles on the environment (e.g., pollution, sprawl); and promoting pedestrian, cycle and transit use Traffic calming objectives include: achieving slow speeds for motor vehicles; reducing collision frequency and severity; increasing the safety and the perception of safety for non-motorized users of the street(s); reducing the need for police enforcement; enhancing the street environment (street scaping); encouraging water infiltration into the ground; 1 Page 3 of 38
increasing access for all modes of transportation; and reducing cut-through motor vehicle traffic. Tonight for discussion with the Commission, city staff will present a brief overview of traffic calming, various traffic calming techniques, results of a survey of local government traffic calming programs and a recommendation on how to proceed. To get a better understanding, City staff surveyed and research other Florida local governments, both municipal and county to ascertain how (if at all) they approach traffic management on residential streets and neighborhoods. Staff researched the following local governments: New Port Richey; Port Richey; Zephyrhills; Dunedin; Safety Harbor; Largo; Pinellas Park; and Pasco County Direction Requested: Direct staff to prepare a traffic calming program based on recommendation from worksession. 2 Page 4 of 38
Traffic Calming Work Session 10.25.16 Page 5 of 38
What are Objectives of Traffic Calming? Page 6 of 38 To cause motorists to drive slower. Increase driver attentiveness in residential areas. Encourage drivers to stay on collector system and not cut through residential streets Increase pedestrian safety Return residential streets to multi-modal use (bike, pedestrians, vehicles, etc.)
What is Traffic Calming? Page 7 of 38 Traffic calming is a system of design and management strategies that aim to balance traffic on residential streets with other uses and modes. Traffic Calming is founded on the idea that streets should help create and preserve a sense of place, that their purpose is for people to walk, stroll, look, gaze, meet, play, shop and even work alongside cars but not dominated by them.

How do local governments address traffic calming? Page 31 of 38 Zephyrhills: No formal Traffic Calming program NPR: No formal Traffic Calming program Port Richey: No formal Traffic Calming program Largo: Formal Traffic Calming program Dunedin: Formal Traffic Calming program Tallahassee: Formal Traffic Calming program Pasco County: Formal Traffic Calming program Pinellas Park: Formal Traffic Calming program
Common Thread Page 32 of 38 Traffic Calming program follows a Policy Statement developed by the City Commission. All local governments require initiation by residents. Traffic Calming program applies to residential and or neighborhood streets only. Speed study is one factor to be analyzed to determine if traffic calming is warranted. The first traffic mgt tool is education and traffic/ speed enforcement. Traffic Calming Handbook is developed by City for residents
Common Thread 2 Page 33 of 38 Traffic calming measures/devices shall be planned, designed and installed in keeping with sound engineering and enforcement practices. Split on local governments that budget annually for traffic calming improvements or require residents to pay for improvements/devices. Speed study is completed to determine if devices are warranted. Traffic calming measures/devices shall be planned, designed and installed in keeping with sound engineering and enforcement practices. Traffic Calming Handbook is developed by City for residents
Of Note Page 34 of 38 City of Largo does NOT install speed humps/ City of Safety Harbor requires Public Meeting. Split on local governments that budget annually for traffic calming improvements or require residents to pay for improvements/devices. Pasco County does not pay for traffic calming improvements. Speed study is completed in all local governments to help in determination if traffic control measures are warranted. Traffic calming measures/devices shall be planned, designed and installed in keeping with sound engineering and enforcement practices.
Advantages of Traffic Calming Page 35 of 38 Advantages Reduces speeds in areas where traffic calming devices are installed. Self Enforcing May reduce cut through traffic Reduces need for traffic enforcement Streets become safer, neighborhoods become safer
Disadvantages of Traffic Calming Page 36 of 38 Disadvantages Increases Fire and EMS response times. May increase speeds between humps/tables. May create noise. Requires additional signage and markings Increased maintenance costs.
Our Recommendation Page 37 of 38 1. Adopt policy statement on safe streets and traffic calming. 2. Adopt a program that accommodates residents concerns regarding residential traffic management, including traffic calming. 3. Adopt a program similar to the Pasco County Traffic Calming Program
Program Highlights Page 38 of 38 1. City maintained local residential streets only. 2. Posted speed of 30 mph or less 3. 85 th percentile speed 5 mph or greater over posted speed. 4. Pavement width 24 feet or less. 5. Average daily traffic volumes of 3000 or less. 6. Cost of improvements borne by property owners.
