Emerging Issues in Transportation PUBLIC WORKS DEPARTMENT M E M O R A N D U M DATE: August 5, 2019 TO: Ryan McIrvin, Chairman Members of the Transportation/Aviation Committee FROM: Gregg Zimmerman, Public Works Administrator Jim Seitz, Transportation Systems Division Director STAFF CONTACT: Chris Barnes, Transportation Operations Manager SUBJECT: Speed Limit 20 mph on City of Renton Residential Neighborhood Streets ISSUE: At the May 20, 2019 City Council meeting, the City Council directed the Administration to prepare an ordinance to change the citywide defacto speed limit from 25 mph to 20 mph on residential neighborhood streets. Should the City Council rescind the stated May 20, 2019 action, and direct the Administration to prepare an ordinance to change the speed limit from 25 mph to 20 mph on residential neighborhood streets on a case‐by‐case basis, and to establish a procedure for the City to evaluate and decide upon requests to lower the streets’ speed limit? RECOMMENDATION: Rescind the May 20, 2019 action by City Council to direct the Administrator to prepare an ordinance to change the citywide defacto speed limit from 25 mph to 20 mph on residential neighborhood streets. Direct the Administration to prepare an ordinance to change the speed limit from 25 mph to 20 mph on residential neighborhood streets on a case‐by‐case basis, and to establish a procedure for the City to evaluate and decide upon requests to lower the streets’ speed limits. Recommended procedure to establish a 20 mph speed limit on residential neighborhood Streets: 1. A requestor will meet with a designated Public Works Transportation Systems Division staff member to discuss the requirements to begin the process for obtaining approval to reduce the speed limit from 25mph to 20mph. 2. In order for the City to consider the request, the requestor will be required to gather signatures on a petition signed by at least 10% of the residents, building occupants or property owners in the area of interest endorsing lowering the speed limit to 20 mph. AGENDA ITEM #1. a) Page 2 of 5 C:\Users\jmedzegian\Desktop\Speed Limit 20 Application revd 6.docx 3. Upon receipt of the petition signed by at least 10% of the residents, business occupants or property owners, the City will establish a preliminary logical boundary around an area to be considered for the speed limit change. 4. The City will then provide the requestor with a detailed map showing the boundary of the logical area for the speed limit change. 5. The City will then ask the requestor to turn in a petition to the Public Works Transportation Systems Division signed by at least 50% of the residents, building occupants or property owners in the area of interest endorsing lowering the speed limit to 20mph. 6. Upon receipt of the petition signed by at least 50% of the residents, business occupants or property owners, an agenda bill including an ordinance will be presented to the City Council requesting approval of the petitioners’ request that the speed limit on the residential neighborhood streets in the subject area be reduced to 20 mph. 7. Upon City Council approval and adoption of the ordinance, staff will install the signs showing the speed limit in that area to be 20 mph. BACKGROUND: COUNCIL MEETING REFERRAL– 5/15/2017 MOVED BY PERSSON, SECONDED BY PÉREZ, COUNCIL REFER THE TOPIC OF SPEED LIMITS TO THE TRANSPORTATION COMMITTEE. – Moloney & Milosevich COUNCIL MEETING – 5/20/2019 Council concurred with the Transportation (Aviation) Committee report recommending concurrence with the staff recommendation to prepare an ordinance to change the defacto Speed Limit of 25 mph on residential neighborhood streets to Speed Limit 20 mph. LEGISLATIVE AUTHORIZATION TO ENACT SPEED LIMIT 20 MPH IN LOCAL JURISDICTIONS  In 2013, the State of Washington amended RCW 46.61.415 under House Bill 1045 by adding Section (3) which allows cities and towns to establish a maximum speed of twenty (20) miles per hour on non‐arterial roads in residential or business districts.  In paragraph (b), cities and towns may do so without a traffic engineering study provided that they develope procedures for doing so.  If a city or town does lower its speed limit to 20 miles per hour under this code, they may, if they decide, restore the previous speed limit without a traffic AGENDA ITEM #1. a) Page 3 of 5 C:\Users\jmedzegian\Desktop\Speed Limit 20 Application revd 6.docx engineering study, provided that the city or town does so within one year of the initial speed limit reduction. ESTIMATED COST OF ESTABLISHING A CITY‐WIDE DEFACTO SPEED LIMIT OF 20 MPH ON RESIDENTIAL AND BUSINESS DISTRICT NON‐ARTERIAL STREETS The estimated cost of changing out approximately 450 existing Speed Limit 25 mph signs to Speed Limit 20 mph signs is $20,500. LACROSSE NEIGHBORHOOD SPEED STUDY The speed study results for the LaCrosse neighborhood are summarized below in the tables and narrative. Speeding was considered to be five miles per hour over the speed limit for the study. Our study included Lincoln Avenue NE, north of NE 34th Place and Monterrey Court NE, north of NE 33rd St. for the week of March 13th – 19th, 2019.

The 85th percentile speed represents the speed that 85% of the motorists are not exceeding. With the remaining 15% of motorists, all but a few are staying below 30 mph. The vast majority of the motorists are staying below or one mph over the 25 mph Speed Limit. However, entering the street conditions and collected speed data into the USLIMITS2 program, the recommended speed limit came out to 20 mph. AGENDA ITEM #1. a) Page 4 of 5 C:\Users\jmedzegian\Desktop\Speed Limit 20 Application revd 6.docx USLIMITS2 – FHWA PROGRAM TO DETERMINE SPEED LIMITS USLIMITS2 is an analytical program developed by the Federal Highway Administration that, given a set of roadway conditions, can determine an appropriate speed limit. Applying the USLIMITS2 program to the data collected for the residential streets in the LaCrosse neighborhood, it recommends a speed limit of 20 miles per hour. A major component of the parameters that influenced the outcome was using the average speeds on the majority of the streets plus 5 mph that resulted in the Speed Limit 20 mph recommendation. SPEED LIMIT 20 MPH IN OTHER COMMUNITIES City of Seattle  Currently, the City of Seattle remains the only community in Washington that reduced the speed limit on their residential streets to 20 miles per hour. They also decided to reduce the speed limit on arterials by five mph.  It established a blanket procedure which applies to every road, instead of individual roadways on a case by case basis.  In additional to police enforcement, a highly visible part of its Vision Zero to reduce crashes campaign are yard signs which state, “20 is Plenty.”  Vision Zero literature typically expresses the survival chance of pedestrians for a given impact speed: at 20 miles per hour, 9 out of 10 pedestrians survive.  Several cities in the United States have adopted Vision Zero as their philosophy regarding road design and operations. Portland, Oregon  In 2011, House Bill 3150 in the State of Oregon allows local authorities to decrease speed limits by five miles per hour on residential streets but requires volume and speed thresholds to be met.  In June of 2017, the governor of Oregon signed into law House Bill 2682 which allowed the City of Portland to decrease its speed limit on residential streets citywide to 20 miles per hour.  Like Seattle, Portland has adopted a residential street speed limit of 20 miles per hour throughout the entire city, in the spring of 2018. The City of Portland has also adopted a campaign to give away free “20 is plenty” yard signs to publicize its new speed limit. New York, New York  In May of 2011, the City of New York established their first 20 miles per hour slow zone in the Claremont Neighborhood and extended it to a total of 28 neighborhoods.  In 2015, the City of New York discontinued their 20 miles per hour Slow Zone program and did not extend to any additional neighborhoods, but now AGENDA ITEM #1. a) Page 5 of 5 C:\Users\jmedzegian\Desktop\Speed Limit 20 Application revd 6.docx concentrate on safety measures for arterials to reduce traffic injuries and fatalities. cc: Gregg Zimmerman, Public Works Administrator Jim Seitz, Transportation Director Bill Judd, Police Sergeant Daniel Figaro, Police Commander AGENDA ITEM #1. a) AB - 2422 City Council Regular Meeting - 15 Jul 2019 SUBJECT/TITLE: Change Order No. 2 to CAG-19-001 with R.W.
