California administrative rulemakers recently moved a step closer to reforming the section of the California Environmental Quality Act (CEQA) that has compelled cities to focus undue attention on the age-old Automobile Level of Service (LOS) threshold for impacts of new projects and has led to the construction of excess off-street parking.
As we documented on Streetsblog, over-reliance on LOS considerations by planners has traditionally led
to widening intersections and roadways to improve the flow of
automobile traffic at the expense of other modes. If the amendments
made by Natural Resources stand and are formalized by January 1, 2010,
the deadline for the changes, cities and counties around the state will
have the flexibility to consider capacity metrics like LOS alongside
other metrics that prioritize transit, pedestrians, and cyclists. The
new rules would even allow city planners to walk away from LOS
From the introduction to the proposed changes:
The intent of those amendments was to recognize a lead agency’s discretion to choose its own methodology for determining transportation-related impacts of a project while ensuring that all components of a circulation system are addressed in the analysis. The proposed revisions would refocus the question from the capacity of the circulation system to the performance of the circulation system as indicated in an applicable plan or ordinance. The proposed revisions also clarify and update language regarding safety considerations and other mass transit and non-motorized transportation issues.
In San Francisco, Mayor Gavin Newsom's Office of Economic and Workforce Development and the City Attorney have been collaborating with the San Francisco County Transportation Authority (TA) to replace LOS with a new metric for measuring the projected environmental impacts of a development or a project by the total number of new automobile trips it will generate (ATG). The city and county believe this new metric would move the focus away from how many cars move through a particular intersection to how many additional cars would be added to the total traffic picture. By default, this metric would prioritize transit improvements, bicycle infrastructure, and pedestrian safety measures, none of which would add automobile trips.
"This is a fantastic development with tremendous impact for transportation analysis in California," said TA Executive Director Jose Luis Moscovich in an email. "We are optimistic that, after two rounds of hearings and comments, the CEQA guidelines will drop references to congestion and automobile LOS. The Authority is proud to have worked hard with our partners at the Mayor's office and City Attorney's office to bring about this exciting reform."
