60th DR NE (Grove ST to 88th ST NE)

A survey was performed in July of 2021, in which all properties were solicited within 600' of a proposed traffic calming devices or whose sole access(es) would be impacted by traffic calming device installation.  To move forward with installation, greater than 60% of respondents were required to tally "yes" for the proposal.  Based upon the survey, 77% were in favor of the project consisting of three (3) speed tables and two (2) raised crosswalks.  Construction is scheduled for fall of 2021 or spring of 2022.

The City of Marysville had been informed of traffic safety concerns within the neighborhood.  Based upon these concerns, the Public Works Department through the Neighborhood Traffic Safety NTS) program evaluated each concern including performance of traffic counts upon several neighborhood streets.  The traffic counts are summarized below:

60th DR NE
(between 83rd PL
NE & 86th ST NE)
1555 29.0 34.1 11.6%

The 85% speed is the commonly accepted engineering value indicating the speed at which 85% of drivers fall under and is found to be the speed at which the majority of drivers feel is a safe speed given the roadway conditions and surrounding environment. The 85% speed is also the value typically used to set speed limits and evaluate compliance with speed limits.

Residential roadways with a consistent speeding problem which may be effectively altered with traffic calming device installation typically have greater than 3% of drivers traveling at greater than 10 mph over the speed limit.

Based upon the cumulative results of the neighborhood traffic data, the Public Works Departments through the NTS program has determined that traffic calming device installation is necessary upon 60th DR NE from Grove ST to 88th ST NE.

A survey will be performed in July of 2021 to solicit approval from all properties within 600' of a proposed traffic calming devices or whose sole access(es) would be impacted by traffic calming device installation.  To move forward with installation, greater than 60% of respondents are required to tally "yes" for the proposal.  Based upon the survey, 77% were in favor of the project consisting of three (3) speed tables and two (2) raised crosswalks. 

This NTS project proposal includes the installation of three (3) speed tables and two (2) raised crosswalks at the following approximate locations: 

  • 8524 60th DR NE (speed table)
  • 60th DR NE & 83rd PL NE (south leg raised crosswalk)
  • 8114 60th DR NE (speed table)
  • 7920 60th DR NE (speed table)
  • 7724 60th DR NE (raised crosswalk)
