M/S/C/U (Harris/McVay) to approve the minutes of the September 17, 2009 meeting with revision on Item 4.1, third paragraph to read “Mike Talley reported that the project cost of $1,174,150 is 100% funded”.




4.1    Thunderbird Drive Status Report

Lisa Bobadilla provided an overview on the status of Thunderbird Drive.   She noted that the RTC program was adopted by the City Council in 1998 and amended in 2006.  In summary, the RTC process related to Thunderbird Drive includes traffic counts, warrant analysis, and notification mailing to 210 residents within 1,000 ft. radius of petitioner’s home address.  Lisa indicated that TAC made the following recommendations at the July 16, 2009 public hearing:

  • Implement stop sign warrant analysis
  • Identify/analyze raised crosswalk
  • Identify potential speed hump location(s)

Lisa Bobadilla reported that a stop sign analysis on Thunderbird Drive at four locations was conducted from September 21, 2009 to October 5, 2009.

Travis Yokoyama, Transportation Specialist – Contractor, discussed the multi-way stop sign warrant analysis.  Travis indicated that total vehicle volume entering an intersection from all approaches for any 8 hours on an average day must average 144 vehicles per hour while minor streets must average 48 vehicles per hour.  Two categories include volume and accident.   Based on the data collected by staff, the four intersections listed below are not eligible for the installation of an All-Way stop sign. 

  • Thunderbird Drive @ Sciota Ave. – not warranted
  • Thunderbird Drive @ Thunderbird Place – not warranted
  • Thunderbird Drive @ Olympic Fields Drive – not warranted
  • Thunderbird Drive @ Burning Tree Drive – not warranted

The “proposed next steps” are as follows:

  • Deploy the RTC radar trailer
  • Initiate discussions with Traffic Engineering related to raised crosswalks
  • Initiate discussions with Traffic Engineering, Fire District, and Police Department and develop  “proposed”speed hump locations
  • Present proposed speed hump locations to the TAC at the November meeting
  • Prior to public hearing, identify 1,000 ft. radius from each speed hump locations and notify residents
  • Schedule a public hearing which could be held either in December 2009 or January 2010

Jim McVay asked for clarification on the issue of raised crosswalk.  Harvey Riggs explained that the idea to explore a raised crosswalk was to satisfy the need of the golf cart crossings between Thunderbird Drive and Sciota Avenue and the need for the speed humps on Thunderbird Drive. 

Lisa Bobadilla responded to Jim McVay’s inquiry about the impact of the TRAFFIX Program stating that staff has seen an increase in the number of pick up and drop off at the back of Walt Disney Elementary.  Lisa also stated that staff is working with Police Department and the Walt Disney school principal to improve the circulation.  As a result of the TRAFFIX Program, a decrease in vehicle volume along Thunderbird Drive has been observed. 


Corey Lyons, Thunderbird Drive, stated that Thunderbird Drive is still unsafe with cars speeding from 55 to 60 mph.  Mr. Lyons indicated that the issue of speeding has been an issue for residents for a long time. He noted that the City analysis showing an average of 38 mph is the real issue.  Mr. Lyons also articulated that the requirement of 144 vehicles per hour is a heavy volume that is difficult to attain.  He also mentioned that the safe route to school due to its proximity to Walt Disney School has never been addressed.  Mr. Lyons said he wants something implemented to minimize the risk of speeding and its potential threat.

Eric Thompson, Thunderbird Drive, stated that he is not concerned about the volume of vehicles on Thunderbird Drive but he is bothered by the speeding issue which remains constant.  Mr. Thompson said they need speed humps and want a safe street.   

Brandon Ferrell, Thunderbird Drive, stated that he has the same concern as his neighbors who support the petition emphasizing that neighbors were clear about the request for speed humps.  He pointed out that the street is designated as safe routes to school; however, it doesn’t have one stop sign nor does it have one crosswalk on the entire safe route which does not make sense.  He is asking the City to revisit the safe routes to school separately in addition to the installation of speed humps.  Mr. Ferrell said that it’s time to address the safe routes to school matter. 

Harvey Riggs stated that that crosswalk issue has been discussed at the July 16, 2009 Public Hearing meeting in response to the public input.  He added that one of the reasons for conducting the stop sign warrant analysis on Thunderbird Drive was to find a location where a stop sign can be placed as well as a crosswalk.  Until the City identifies an appropriate location for speed humps, it’s lnot a good idea to select the crosswalk locations.  Harvey indicated that staff and TAC are working on this request.

5.2       County Connection Citizen Advisory Committee (CAC) Status Report

Harvey Riggs does not have any updates at this time.  The County Connection CAC meeting was cancelled.

5.3       Active Residential Traffic Calming (RTC) Streets Status Report

Travis Yokoyama gave an update on the following active RTC streets:

  • Greenwich Drive – Selective enforcement and radar trailer has been deployed. 
  • N. Wedgewood and Camissia Way – this location meets the warrant for a stop sign and staff will proceed with the stop sign installation.
  • Morgan Drive – the RSDS has been reconfigured and recalibrated and the issue had been resolved where it catches vehicles in opposite direction.
  • East Branch and Sherwood – staff recommended increasing signage and altering signal timing and add an additional crossing guard.
  • Japonica and Paddington – sign survey had been completed.  Engineering will work with the County to perform a stop sign analysis as it is not the City’s jurisdiction. 

There were no comments from the TAC on active streets.
