Homes and laterals

South Whittier, south of the city limits, is largely made up of postwar single-family neighborhoods. Many of these homes are slab-on-grade tract houses from the 1950s and 1960s, with original laterals of clay or cast iron unless they have since been replaced.

The sewer issues are the same as across the city line: roots at clay joints, scaled cast iron under the slab and sags near the street. What differs is the paperwork and which agency to contact.
