Dont worry, there will be countless studies on this matter, which will then be sent to city council for further direction. Council will then refer the matter back to city staff to further study this issue, then city staff will come up with a revised list of proposals. Once this list of proposals is sent back to city council for voting, they will vote to defer the matter altogether until "funds become available".
This is how this city works and it's shamefully embarrassing. Just by comparison; London, England (a city we love to compare ourselves with since they are world-class) managed to propose and install physical barriers on many of their bridges in less than 60 days. In this city, even for something as simple as physical barriers to prevent incidents like this, it would take countless months (if we were lucky) to get anything like that installed.
