BACKGROUND Speed cushions are either speed humps or speed tables that include wheel cutouts to allow large vehicles to pass unaffected, while reducing passenger car speeds. They can be offset to allow unimpeded passage by emergency vehicles and are typically used on key emergency response routes. These should not be confused with low speed parking lot speed bumps that are not allowed in the right -of -way due to higher speeds and liability. Residents within the S 160th St project limits have expressed concerns over vehicle speeding. After conducting a RADAR speed study, the determination was made to design and install non- permanent speed cushions as a pilot project. The speed cushions would also help establish traffic patterns prior to the 42nd Ave S Phase III construction road closure, since this roadway segment on S 160th St will be a detour route for the 42nd Ave S Phase III Project. DISCUSSION The S 160tt, St Speed Cushion Pilot Project's design phase has been completed. A project plan sheet with proposed placement of speed cushions is attached. Public Works can install speed cushions on the subject roadway segment, S 160th St from 42nd Ave S to 51st Ave S. Before and after speed data will be collected and analyzed to assess the impact of the speed cushion installation. FISCAL IMPACT Labor for installation will be completed in house. The approximate total procurement cost for the six speed cushions and sign locations is $33,000.00. There is currently $75,000 budgeted in Traffic Calming. RECOMMENDATION Information only.
