The lieutenants will also be allowed to quickly send out information to assist residents during an emergency, Silversparre said. Notices can be sent out by region or community, he added.
"What's really neat about this program, you can put a ZIP Code of another area where you are monitoring your elderly parent or you are watching your college-age child … and get notifications of issues in that area as well," Silversparre said.
The department will use Nixle to disseminate the information, which can come in four color-coded messages detailing specific incidents, according to the Sheriff's Department.
A red "alert" message would be used for kidnappings, an amber alert for crimes where public assistance is needed. Yellow "advisory" messages would be sent when deputies are looking for suspects or sending public safety information.
Green "community" messages would notify residents about crime trends, law enforcement events and can include safety tips, while blue-coded messages would address traffic issues.
Cheryl Davis, president of the Crescenta Valley Town Council, said she had already signed up for the messaging system.
"I think it is very cool because it's specific to actual areas," she said.
Silversparre is expected to formally introduce the new system Aug. 19 at the town council's monthly meeting, she said.
