April 3, 2019, GPU SC agenda comments from Jim Mosher Page 4 of 4
Item IV.b. Housing Element and Regional Housing Needs Assessment
(RHNA) - Status and Schedule
One might have hoped some background information would have been posted to assist
committee members and the public in preparing for this item, including the City's annual Housing
Element status report reviewed by the City Council at its March 26 meeting, as well as the staff
report for that meeting.
Links to the SCAG RHNA page and the HCD RHNA page (including the latter's Public
Participation requirements and advice) would also have been helpful.
Item IV.c. Circulation Element and City's Traffic Model
As with Item IV.b, it would have been helpful to provide some background information for review
in advance of the meeting.
Item IV.d. General Plan and State Mandates
This agenda heading is so terse that it likely does not meet the Brown Act requirement of
meaningfully informing the public of what will be discussed in advance of the meeting, with
enough detail that they can decide whether they should attend, or not.

Item No. 4c Additional Materials Presented At Meeting
Circulation Element and City's Traffic Model
Newport Beach Traffic Analysis Model (NBTAM)
What is it ?
• Computer software platform used to model transportation systems to help plan, design and
operate circulation system.
• Initially created as part of the 1988 General Plan.
• Updated in 1996 to reflect changes initiated by GP Amendments and upgrades to roadway
system.
• A new model was developed in 2004 for the 2006 General Plan.
• Extensive update in 2014 as part of the proposed Land Use Element Amendment.

Item No. 4c Additional Materials Presented At Meeting
Circulation Element and City's Traffic Model
Model Options
• An NBTAM update would maintain the existing model framework. A new model would require
changing the software and re -coding the network. Both options would include latest Orange
County Projections (OCP) 2014 demographic data.
• Development of a new NBTAM model would roughly double the time, effort and cost vs. update.
• An update would be efficient and consistent with OCTA model, and would meet General Plan
needs. A new NBTAM model could incorporate recent VMT analysis requirements.
• Approximate schedule for update is 4 - 6 months. New model development would take
approximately 8 -10 months.
• We would continue to use our long standing on-call modeling consultant. Lead staff members
managed the 2004 model development and the 2014 model update.

Item No. 4c Additional Materials Presented At Meeting
Circulation Element and City's Traffic Model
Senate Bill 743
• Requires changes to guidelines implementing CEQA regarding the analysis of transportation
impacts. Shall go into full effect statewide by July 1, 2020.
• Identifies vehicle miles traveled (VMT) as the most appropriate metric to evaluate a project,
replacing the capacity based level -of -service (LOS).
• SB 743 states that lead agencies have discretion to develop and adopt their own methodology,
thresholds of significance, feasible mitigation measures.
• Basic methodology is
to use the
trip generation to calculate
the project VMT. Then
compare a
project's VMT/capita
(residential
projects) or VMT/employee
(employment projects)
to average
values on a regional basis.

Item No. 4c Additional Materials Presented At Meeting
Circulation Element and City's Traffic Model
Senate Bill 743
• SB 743 states that vehicle LOS may continue to be used for all projects as part of transportation
planning or entitlement review. SB 743 only modifies the CEQA analysis process.
• In addition to the CEQA VMT metric, many cities (San Jose, Pasadena, San Diego) continue to
require that project studies include analysis of local intersection operations using LOS.
• The City Traffic Phasing Ordinance (TPO) will continue to be used in addition to VMT analysis.
• Mitigation for impacts could include capacity improvements to roadway or transit, bike,
pedestrian improvements, or ride -sharing requirements, etc.
