SAN DIEGO - The chairman of the San Diego County Board of Supervisors outlined the state of the county in an annual address Wednesday night.

Before a crowd of about 350 people, Supervisor Ron Roberts talked about a list of key issues including fighting child obesity, helping the homeless, and improving emergency response times.

He said a healthy community starts with healthy children and the children of San Diego need help. The percentage of kids overweight or obese in San Diego is below the national average of 38 percent, but Roberts said the 34.5 percent is still too high.

"A recent study showed San Diego's childhood obesity rate down 3.7 percent, while the majority of California counties saw an increase," said Roberts. "We are working hard to extend this trend."

His plan is to increase more fruits and veggies to the diet, limit recreation screen time to no more than 2 hours per day, include at least one hour of physical activity each day, and eliminate consumption of sugar sweetened beverages.

He said the county has made huge strides in improving the local homeless situation.

"Regionally, we will spend about $185 million this year on programs targeted specifically to serve those who are homeless or at risk of being homeless," Roberts said.

Another area the Board of Supervisors is committed to improving is fire and emergency services, he said.

"What was once a haphazard array of cash-strapped agencies with incompatible equipment and differing levels of training is now a stronger, more cohesive firefighting force," Roberts said.

He added that more than $200 million has been invested in fighting fires and fire prevention services over the last decade. Roberts said the board is looking at applying technologies used by the military to improve the response of future emergencies.
