 Project Manager Michael Prousa gives presentation on the Gartner Road
 speeding and stop request traffic investigation.

 Marilyn Schweitzer states that she agrees that Gartner Road is an issue and
 she is looking forward to the after studies following quick implementation of the
 recommendations. She states that additional stop signs will not help but that
 enforcement is key. Gartner is not patrolled as much after traffic officers have
 been cut.

 Bob White mentions the intersection of Gartner and Edgewater and would like
 the City to investigate improving the crossing and intersection. He states that
 cars go at different speeds as they come down Gartner and he hopes that the
 study differentiates between the different speeds. Bob White states that many
 pedestrians/bicyclists use this stretch of roadway. He states that the road is
 populated with many children and that it is a time saver for vehicles to avoid
 streets with traffic lights. He states that if a person is struck on Gartner there is
 a high chance of an injury because of the high rate of speed that vehicles are
 traveling at.

 Chairman Melaniphy asks staff to clarify some of the points that were raised by
 Bob White.

 Prousa states that Gartner and Edgewater and the bicycle trail crossing will be
 evaluated in May of 2023 when the trail use will be higher than it is today. Staff
 can bring the report of that intersection back to TAB at that point.

 Bill Simon states that the crosswalk at Gartner and Edgewater is very heavily
 populated. He states that when the crosswalk is being used heavily vehicles
 stop often. During the evening and at night people do not stop and are speeding
 across the bridge. Bill mentions that the City should look at a pedestrian flasher
 sign for the location. He asks staff if bicyclists would be allowed to bike over the
 marked choker.

 Prousa states that they would be allowed to bike along the marked choker. He
 states that Gartner Road is a on-street bicycle path and that bicyclists are
 expected to share the road with vehicles and vice versa.

 Prousa clarifies that the in-pavement stop for pedestrian signs are placed at
 crossings from early May to late October.

 Howenstine appreciates the staff's attention to detail.

 Seeberg appreciates the staff's quick turnaround on the study. He asks about
 collector streets and why Gartner is a collector.

 City Traffic Engineer Andy Hynes states that the City has a master thoroughfare
 plan that divides the streets into different classifications like local streets,
 collectors, and arterials. He states that the reasons are based off their
 connectivity and function. The volumes do not define the classification but they
 typically have similar ranges and speeds.

 Seeberg asks what else can be done to the intersection of Gartner and
 Edgewater and how does the City look at these requests.

 Prousa states that some of the criteria that staff looks at sight distance,
 volumes of trail users and vehicles, speeds of vehicles. They also have options
 of tree trimming, crossing enhancement, and engineering solutions to have the
 intersection perform more safely.

 Seeberg asks if there is anything else that can be done at the hill to have
 vehicles drive slower. He also asks if we could put another 25 mph sign for
 vehicles as they leave the curve towards the hill.

 Prousa states that staff believe that taking the tiered approach to lowering
 speeds is the best option currently, Prousa states that an after study will
 determine whether or not the tools are working to the desired impact. Prousa
 states that a 25 mph sign is located after the curve for the WB traffic.

 Seeberg states that he uses the area a lot for biking. He asks if the sharrow
 markings are in place on this stretch or if they were looked at by staff.

 Prousa states that staff considered them but were focusing on speed reduction
 tools.

 Seeberg states that he would like to see more traffic officers out on the streets
 and appreciates the effort on situations like this.

 Hurley states that he is happy for the quick turnaround on the study and asks for
 staff to explain what the 85th percentile means.

 Prousa states that the 85th percentile is what 85 percent of vehicles drive at or
 below. He states that the number is used by the industry for making traffic
 decisions.

 Prousa clarifies that the 85th percentile includes the outliers.

 Melaniphy asks Sergeant Krakow what his traffic units see out in the field.

 Sergeant Krakow states that they focus on the outliers and that the percentages
 show that they are infrequent.

 Hurley asks about the traffic collection units that were used for the study and if
 they prohibit speed when drivers see them.

 Prousa states that the traffic data collection units are Jamar and Numetric
 counters. The Jamar units were used for the Gartner Study. Staff has no reason
 to think that vehicles drive slower when approaching a data collection device.

 Hurley asks what times the data was collected.

 Prousa states that the data is collected 24 hours a day for a full week. He also
 states that the output is in multiple types of time intervals. He states that this
 helps finding times of day that speeding is occurring.

 Hurley asks what kind of crash data is available to City staff.

 Prousa states that staff has access to any crash that a police report has been
 filed for. He states that staff typically look at the last 3 to 5 years of crash data.

 Hurley asks if the speed limit signs that already have banding, if they will be
 replaced or additional ones will be placed.

 Prousa states that those will be an addition to the speed limit signs that are out
 there.

 Webb states that the quick turnaround was appreciated.

 Webb asks what the next steps are for implementation.

 Prousa states that signage will most likely be placed this year and that the
 pavement markings will be a part of the 2023 pavement markings contract.

 Webb asks if TED can handle the implementation on their own.

 Prousa states that yes, this report is what TED sees on a weekly basis and are
 able to implement the recommendations without City Council approval.

 Melaniphy states that the reason this has ran so smoothly was because of the
 traffic calming toolkit that had a public process in 2020. He thanks the public,
 staff and TAB for all the questions and contributions.
