City Council to Consider Roadway Configuration for the Parkway Room Portion of Miller Avenue

February 21, 2019

At their March 4, 2019 meeting, the Mill Valley City Council will consider a recommendation for the permanent roadway and parking configuration for the Parkway Room portion of Miller Avenue, from Millwood Street to Willow Street. The recommended configuration provides a one lane outbound configuration with no curbside parking allowed, and a one lane inbound configuration with curbside parking allowed.

The Miller Avenue Streetscape Plan, adopted by City Council in 2011, included two travel lanes in each direction in the Parkway Room section. During construction, this segment was re-striped to one lane to allow for additional temporary parking. During construction of the project, the City received community interest to both maintain the one lane configuration and to revert to the original adopted plan.

Council, based on their adopted Core Value of a balanced, inclusive, and open approach to policy-making, initiated a discussion of the one lane configuration on Miller Avenue. They held three public hearings on the issue, reviewed public comments, sought expert analysis from engineering and public safety and, as a result, initiated a one year pilot project.

Now that sufficient time has elapsed to provide real-life experience with the function of the lane configuration, and that pertinent data has been collected, Council will receive the information needed to objectively evaluate a recommendation and options for the Parkway Room’s permanent configuration.

At their upcoming meeting, Council will review an evaluation of the pilot project including an environmental analysis, transportation and parking survey, and evaluation of the effectiveness of the lane configuration for emergency evacuation. The environmental analysis has determined that there are no significant impacts associated with the one lane configuration. Furthermore, the transportation study concluded that, for daily use of Miller Avenue, the one lane configuration has not negatively impacted traffic congestion, safety, travel speeds or cut-through traffic. The study collected and analyzed vehicle traffic counts, neighborhood cut-throughs, vehicle traffic speeds, collision data and parking demand. Additional details about this and other recommendations can be found in the Staff Report (see below).

Council will also consider input from City public safety officials, who previously advised that the one lane roadway configuration accommodates well emergency and potential evacuation operations, and that the one lane configuration is wide enough to accommodate two streams of traffic in the same direction.

At the meeting, staff will present the Council with a recommendation and options to consider for the permanent configuration. These include:

  1. Two travel lane configuration (the approved Streetscape Plan). 
  2.  One travel lane/existing configuration (the current pilot configuration). 
  3.  One travel lane configuration modified to prohibit curbside parking during nighttime hours and/or certain times of year. 
  4.  One travel lane configuration modified to eliminate all curbside parking. 
  5.  Recommended Configuration: One travel lane configuration modified to eliminate outbound curbside parking (maintain inbound parking). 

Council will review the above options based on expert and environmental analysis, technical data and community input, and will then provide direction to staff.
