National City is working to create new housing and held a housing density workshop Thursday to discuss options. Mayor Ron Morrison said nearly every housing unit in the city is full which puts the city's vacancy rate close to zero. With much of the city already developed, the only option is to build higher. The city also has one of the lowest homeowner rates in San Diego County. "A lot of cities have what they call their urban reserves which is open spaces," Morrison said. "Our urban reserves is the weeds behind the backstop at the little league field. There are no open spaces. up is the only way we can go." As many cities look to build more affordable housing, National City is needing to do the opposite. "We have so much low-income housing here they say we're kind of out of balance on that. While other cities are being given a lot of low-income housing the numbers for us are actually for the above-moderate," he said.
