Two telephone town halls were conducted to expand outreach to those who were unable to attend community meetings and are less likely to see digital ads, particularly older populations. Speakers and a moderator guided the discussion in English with prepared remarks and answered questions and comments from the audience. Polling questions were used to gauge audience priorities. One telephone town hall covered the southern portion of the river from Downtown LA to Long Beach, and one covered the north and west from Downtown LA to Canoga Park. Nearly 5,600 people participated, with over 500 participants on the line at any given time.

Prior to being an interactive version of the Master Plan, this website functioned as a digital archive for the master planning process, a bulletin board for upcoming meetings and events, and a portal to digital surveys. The website provided access to all public presentations, digital mapping, technical memos, research, and drafts of the Master Plan document.

Social media posts, social media ads, and a monthly email communicated the breadth of river-related issues, the planning process, and engagement opportunities to a wide, diverse audience.
