Will morning rush hour traffic flow be a problem?

1 Minute Read

We have gotten questions about how Solana Torrance will impact traffic flow during weekday rush hour.  Some anticipate that because there will be 248 units, there will be 500 cars added to Via Valmonte and Hawthorne Boulevard during peak morning times.  However, independent traffic engineering studies indicate that during the highest impact hours of 7:00 am and 9:00 am, 126 trips (101 outbound and 26 inbound) can be expected.

This estimate reflects the conclusions of the comprehensive traffic-impact study which was completed by an independent, third-party, licensed traffic engineer and submitted to the City for analysis.

To further illustrate these conclusions, here is a video series (taken by a third party, traffic count data collection firm) of peak hour traffic at a comparable Torrance area multi-family project (Alta South Bay) which has 257 units.  This video series was shot on a Wednesday morning between 7:00AM and 9:00AM. The two-hour time frame has been uploaded in four different 30 min segments

  1. 7:00AM - 7:30AM (as seen below)
  2. 7:31AM - 8:00AM (link)
  3. 8:01AM - 8:30AM (link)
  4. 8:31AM - 9:00AM (link)

It should be noted that Alta South Bay has only one exit, and Solana Torrance will have two, one exiting onto Hawthorne and one exiting onto Via Valmonte.  Also, Alta South Bay has no signal light whereas, after Solana Torrance’s road improvements are complete, the intersection will include two dedicated left turn lanes.  Per the conclusions of the traffic engineering firm, the level of service (i.e. the traffic impact) at Via Valmonte and Hawthorne Boulevard will remain unchanged.

For your convenience, we have summarized the results in the table below.
