Start with official information.
The city’s Crisis Communications page describes several public information channels, including emergency text messaging, city alerts, and coordinated county warnings. Use that official page for the current choices.
Official resources checked October 26, 2026. Links identify independent public resources and do not imply affiliation or endorsement. Contact and reporting directions should be checked on the agency’s own website.
Use more than one official information channel.
San Ramon's crisis-communications page describes a coordinated mix of Nixle text alerts, city GovDelivery messages, county Community Warning System notices, Wireless Emergency Alerts and other communications. The city presents these as complementary ways to reach the public during a significant incident, rather than one channel that replaces all the others.

Evidence may change how you should report.
The city's police-reporting instructions distinguish eligible self-service reports from matters needing an officer's assistance. In particular, they direct people with evidence such as video surveillance to non-emergency dispatch at 925-973-2779. Check those current instructions before submitting material: an online form's existence does not mean every kind of report or attachment belongs there.

A useful connection keeps the issuing source clear.
A resident may need San Ramon information alongside updates from another city, but the instructions and responsibilities still belong to the agency issuing them. A future Lucas connection should be evaluated on that basis: which department participates, which features are available, and where a related observation actually goes. San Ramon's participation is not established by this page.
Practical local distinctions
Use the route that fits the question.
San Ramon describes a multi-channel communications approach, including local subscriptions, county warnings and WEA. Its reporting guidance is equally specific: a person with evidence such as surveillance video should contact non-emergency dispatch rather than assume the self-service form is the right route. That practical distinction can help useful information reach the appropriate process without presenting Lucas as an existing city reporting channel.
A communication plan can use more than one channel.
San Ramon’s Crisis Communications page explains the city’s information approach, including local subscriptions, county warnings and Wireless Emergency Alerts. Those channels have different purposes and enrollment arrangements. Keep the official instructions for the places that affect your routine, and distinguish them from an app’s followed-department list.
For a significant incident, read the current city or responsible authority’s instructions. A quiet app feed or an absent notification does not establish that there is no incident or that a particular route is open.
Camera evidence can change which reporting route is appropriate.
The city’s reporting guidance directs people with evidence such as surveillance video to non-emergency dispatch rather than assuming the self-service reporting form is appropriate. Check that instruction before trying to fit a file into a convenient online field.
Keep the original material and describe the relevant place and period. If the camera’s displayed time is uncertain, say so. The receiving agency can give its current directions for providing a copy. Product support and this marketing website are not evidence-submission services.
Check the original local instructions.
These are official local resources, independent of Lucas and Sentinel. Their instructions can change. When preparing a report or an alert subscription, use the original page for the current process rather than a saved description of it.
Where Lucas would fit.
A resident might want updates from San Ramon and another place in the same daily routine. Lucas is designed for following participating departments, with the source kept clear on each update. That intended experience does not establish that San Ramon Police Department participates today.
If you have information about a request, the originating agency and the request’s instructions identify the appropriate recipient. A person can notice something relevant outside the city where the request began. Describe the connection, check the supported route and share what you already know without investigating or approaching someone.
The Census estimate linked below describes the place. It does not measure users, agency adoption or notification coverage. For a department considering the products, an evaluation should establish the actual capabilities and responsibilities before the public is invited to rely on a new channel.
Does following a police department replace San Ramon’s warning systems?
No. The city describes multiple official warning and information channels. Keep the appropriate subscriptions and follow current instructions issued by public safety authorities.
How Lucas would fit.
Lucas is designed to let residents follow more than one participating department, receive agency updates, and send relevant information where reporting is active. Sentinel is the corresponding department workspace.
Before relying on any San Ramon feature, confirm that the relevant agency participates and that the feature is available. Continue using official local and county warning channels. For an emergency, call 911.
For department evaluators.
An agency inquiry can establish the actual product fit, the responsibilities for publishing and reviewing information, and the requirements of a limited pilot. No adoption or evaluation by San Ramon Police Department is asserted here.
