Ke Intended Outcome Su orted: Improve or maintain traffic flow. Supporting Data (Surveys, Environmental Scan, etc.): Transportation remains one of the most significant areas to address from the survey results (often mentioned as a key quality of life issue). 24% of residents rated traffic flow excellent or good, and 37% as poor. 35% of residents rated the availability of edestrian trails and bic cle aths/lanes as excellent or ood, and 30% as oor. Issue: Shall the Ci Commission ado t the Resolution? Item Summary/Kecommenaation: In September 2007, the Public Works Department striped and signed bike lanes on 16th Street between Bay Road and Washington Avenue. This required the removal of a left turn lane on 16th Street approaching Alton Road westbound. After the implementation of the bike lanes, residents complained to elected officials and City staff that the elimination of the left turn lane resulted in a significant back-up of vehicles. City staff was directed by the Office of the Mayor and Commissioners to address this issue. The City retained the services of PBS&J to perform a qualitative analysis of the operational conditions of the existing intersection with bike lanes and the results of the study concluded that a queue on the westbound direction was caused by left turn vehicles blocking the westbound through movement. An option to improve this condition would be to iptroduce a left turn lane on 16th Street at Alton Road; however doing so would require either the elimination of the bike lane orelimination ofthe on-street parking on the north side of 16th Street between Alton Road and Lenox Court. At the November 24, 2008 Neighborhoods/Community Affairs Committee meeting, a motion was made to remove the five (5) existing parking spaces on the north side of 16th Street from Alton Road to Lenox Court to allow sufficient space for both the bike lane and a dedicated left turn lane. A relatively high number of bicyclists utilize 16th Street, since it provides directness and connectivity to bicycle traffic generators. The existing bike lanes provide a safer environment for these bicyclists, since the bike lanes minimize potential conflicts between them and motorized vehicles either parallel parked on 16th Street or traveling through the intersection of 16th Street at Alton. City staff met with Miami-Dade County on December 15, 2008 to discuss the intersection and the proposed roadway configuration received preliminary approval. At the January 21, 2009 Neighborhoods/ Community Affairs Committee meeting, a motion was made to approve a proposed cross-section of no on-street parking on the north side, on-street parking on the south side, two travel lanes, a left turn lane, and bike lanes.

Gonzalez DATE: March 18, 2009 SUBJECT: A RESOLUTION OF THE MAYOR AND CITY COMMISSION OF THE CITY OF MIAMI BEACH, FLORIDA, APPROVING A ROADWAY CONFIGURATION FOR 16T" STREET FROM ALTON ROAD TO LENOX COURT THAT CONSISTS OF NO PARKING ON THE NORTH SIDE, PARKING ON THE SOUTH SIDE, TWO TRAVEL LANES, A LEFT TURN LANE, AND BIKE LANES, WHICH BEST SUPPORTS THE GOALS ESTABLISHED IN THE APPROVED 16T" STREET OPERATIONAL IMPROVEMENT AND ENHANCEMENT PROJECT BASIS OF DESIGN REPORT AND WHICH WAS PRESENTED AT THE NEIGHBORHOODS/COMMUNITY AFFAIRS COMMITTEE ON JANUARY 21, 2009. ADMINISTRATION RECOMMENDATION Adopt the Resolution. BACKGROUND A Basis of Design Report (BODR) was prepared for the 16th Street Operational Improvements and Enhancement project and subsequently reviewed and approved by the Commission on September 5, 2007. After existing base data for the project area was collected and analyzed, one of the goals identified in the conceptual design to minimize speeds along the corridor was traffic calming. It was indicated that traffic calming was a major missing element along the entire corridor as well as a primary recommendation for apedestrian-friendly environment along 16th Street. The actual condition of the corridor, undivided with a wide right-of-way, was noted to encourage increased travel speeds. The wide roadway width meant that pedestrians were exposed to significant crossing distances. Sight distance was deficient and parked vehicles and signs obstructed pedestrian's views. Design recommendations included narrower lanes to reduce drive speeds, bulb outs at intersections to announce pedestrian crossings (and reduce pedestrian crossing distances) and special pavement crosswalks and parking lanes to designate these as special areas. As part of the approved BODR some of the site design recommendations to create a more pedestrian-friendly environment included a street cross section consisting of two 10-foot travel lanes, two 5-foot bike lanes, two 8-foot on-street parking lanes, two 12-foot sidewalks in the commercial zone between, Collins Avenue and Washington Avenue and between Alton Road and Lenox Avenue and 6- to 8-foot, variable-width sidewalks in the residential zone, between Lenox Avenue and Washington Avenue, with the planting areas next to private properties varying in width. See proposed cross-section identified in the BODR (Attachment 1, Proposed BODR Cross- sections for 16th Street). The development of the BODR included an intensive public involvement process with substantial public input. The following chart summarizes the underlined preferences of various stakeholders: Decorative Bicycle Wider Enhanced Parking Removal of Stamped Asphalt Lanes Sidewalks Landscapin Encroachments Historical 0 ~ ~ ~ ~ Preservation Board Internal Visioning ~ ~ ~ Session Community 0 ~ Workshop Transportation and 0 ~ ~ Parkin Committee Planning Board ~ ~ ~ • • Flamingo Neighborhood • • Association Finance and ~ Citywide Projects • • • Committee As noted in this chart, almost every stakeholder group preferred bike lanes. In September 2007, the Public Works Department striped and signed bike lanes on 16th Street between Bay Road and Washington Avenue. This required the removal of a left turn lane on 16tH Street approaching Alton Road westbound. After the implementation of the bike lanes, some residents complained to elected officials and City staff that the elimination of the left turn lane resulted in a significant back-up of vehicles. City staff was directed by the Office of the Mayor and Commissioners to evaluate this issue further and determine the viability of these complaints. ANALYSIS Pursuant to these complaints, the City retained the services of PBS&J to perform a qualitative analysis of the operational conditions of the existing intersection with k~ike lanes during the morning (7:00 a.m. to 9:00 a.m.) and afternoon (4:00 p.m. to 6:00 p.m.) peak hours in order to be able to provide an assessment of the existing roadway configuration (see Attachment 2, PBSJ Study). The results of the study provided the following conclusions based on field observations: The right turning vehicles on both directions used the bike lane to turn, forcing bicyclists to use the sidewalk. The stacking on the westbound direction was caused by left turn vehicles blocking the westbound through movement while they wait for an adequate gap from opposing traffic that crosses the intersection. The study concluded that the current condition shows stacking for the westbound movement at the intersection. An option to improve this condition would be to introduce a left turn lane on 16tH Street at Alton Road. Given the current street width, to introduce a dedicated left turn lane would require the removal of the 16tH Street bike lanes from Lenox Avenue up to the intersection at Alton Road or the elimination of on-street parking in the same area. An adverse effect to removing the bike lanes would be that the continuity of bike lanes would be truncated at Lenox Avenue and therefore would introduce a safety issue to bicyclists trying to reach Alton Road as it would force the bicyclists to use the sidewalk or to have to share the street with motorized vehicles crossing 16tH Street at this intersection. A relatively high number of bicyclists utilize 16th Street, since it provides directness and connectivity between major street collectors such as Alton Road to points of destination such as Washington Avenue and the beach as well as other points of interest in South Beach. The existing bike lanes provide a safer environment for these bicyclists, since the bike lanes minimize potential conflicts between them and motorized vehicles either parallel parked on 16th Street or traveling through the intersection of 16th Street at Alton. To evidence this, bicycle counts were conducted at the intersection of 16th Street and Alton Road before and after the bike lanes were striped along 16th Street. Miami-Dade County conducted bicycle counts in February 2007. There were a total of 20 bicyclists counted on a weekday between the hours of 7-gam, and a total of 31 bicyclists on a Saturday between the hours of 12- 2pm. The City of Miami Beach Public Works Department conducted bicycle counts after the bike lanes were striped in May 2008 during the same days and hours. The number of bicyclists increased on the weekday from 20 to 28 bicyclists, and on Saturday they increased from 31 to 121. This dramatic increase demonstrates how well the bike lanes are being utilized by the community, particularly during weekend hours for both transportation and recreational use. Table 1 below summarizes the before and after bicycle counts at 16th Street and Alton Road. Table 1. Bicycle Counts at 16th Street and Alton Road BEFORE AFTER February 2007 May 2008 % Change Weekda 20 Weekda 28 40% Saturda 31 Saturda 121 290% The City conducted additional bicycle counts in November 2008 for all turning movements along both Alton Road and 16th Street between the hours of 4-6pm. According to these counts, there were a total of 91 bicyclists traveling eastbound/westbound along 16th Street and a total of 105 bicyclists traveling northbound/southbound along Alton Road (see Attachment 3, 16th St. and Alton Rd. Bicycle Counts). NEIGHBORHOODS/COMMUNITY AFFAIRS COMMITTEE At the November 24, 2008 Neighborhoods and Community Affairs Committee meeting, a motion was made to remove the five (5) existing parking spaces on the north side of 16th Street from Alton Road to Lenox Court. The Committee deemed that the available right of way can only support two out of three possible uses and that the turn lane and bike lane were higher priority than the parking spaces. This option would allow sufficient space for both the bike lane and a dedicated left turn lane. At the December 10, 2008 City Commission Meeting, the City Commission referred this item to the next Neighborhoods and Community Affairs Committee meeting for additional discussion. Subsequent to the December 10th City Commission meeting, City staff met with Miami-Dade County on December 15, 2008 to discuss the intersection and the proposed roadway configuration received preliminary approval. At the January 21, 2009 Neighborhoods and Community Affairs Committee meeting, a motion was made to approve the proposed cross-section (see Attachment 4, Proposed Cross-section for 16th Street and Alton Road). While the removal of parking spaces is generally of concern anywhere in the City, the intersection configuration recommended by city and county staff addresses a good solution for both bicycle use and safety and for vehicle movements. As such, the trade off of parking spaces in this instance is justified. CONCLUSION: The Administration recommends that the Mayor and City Commission adopt and approve a roadway configuration for 16th Street from Alton Road to Lenox Court that consists of no on-street parking on the north side, on-street parking on the south side, two travel lanes, a left turn lane, and bike lanes. This street cross section best supports the approved BODR for the 16th Street Operational Improvement and Enhancement project goals to improve the safety of the corridor for bicyclists and pedestrians and to enhance the quality of life for local residents and visitors.

PBS&J has performed a field review of the intersection of 16`h Street and Alton Road, and have also reviewed the BODR S'i''1~TCHRO model of this intersection, pravided by the City. Fallowing are the summary and recommendations: • It was identified in the meeting with the City of Miami Beach and PBS&3 on May 6, 2008 that the methodology to be adopted for the study would be - (a) Modify the 2007 PM peak BODR SYNCI~RO model (obtained from the City) for the intersection Ib`~ Street and Alton Road, to test a split phase operation for the Eastbound and Westbound movements. It was agreed that na other parameters in the model would be changed so that the delay before and after maybe compared. (b} Depending on, the delay comparison, a further course of action will be decided, including the possibility of full traffic impact study. • Review of the 2007 PM peak BODR SYNCHItO model showed that the intersection was evaluated with an Eastbound left turn storage lane of Soft and a Westbound left turn storage lane of 110ft. The existing aperatirig conditions are however much more constrained with no left turn storage lanes on the eastbound and westbound direction. The model was modified and the left turn lanes were eliminated and split phase introduced. Table 1 below shows that removing the left turn storage lane, cause significantly more delay to both the approaches and introduction of split phase on the Eastbound and Westbound direction further exacerbate the condition.

It was observed that the existing l/astbound and Westbound vehicular movement at the intersection of 16th Street and Altars Road has a shared operation with only 1 lane sharing the Left, Through and Right turn movements. The roadway at this location also has bike lanes on both sides of the roadways. The signal operation shows the Eastbound and Westbound left turn movements operating on a perrrussive phase. Queues on both directions were observed and sample counts were taken for 15 consecutive signal cycles (130sec per cycle}. The field observation clearly shows no left aver queues on the Eastbound direction and up to 14 cars on the Westbound direction. This does not match with the queues observed in the 2007 PM peak B4DR SYNC13R0 model {the mode] shows total 463veh an the Eastbound and 122veh on the Westbound direction). Table 2 below shows the left over queue data collected in the field.

The queue on the westbound direction was observed to be caused by the left turn vehicles blocking the westbound through movement. As mentioned earlier the left turn movement operates on a percussive phase and has to wait for adequate gap from opposing traffic to cross the intersection. The qualitative field assessment shows that westbound movement has queues, which spill back to the intersection on the e~s# o~ .A1#on Road.. This condition could be unproved by introducing a left turn lane. The physical geometry of the roadway at this point of time does not offer any other option than removing the bike lane and installing a left turn lane. However it may be Hated that the removal of a bike lane from a particular section of roadway with continuous bike lanes, may not be safe as it would force the bikers on the sidewalk in that section. ~.
