Hills, trees and older houses
The College Hills area is known for established homes on rolling and sloped streets near the Whittier College campus. Many houses predate the postwar building boom, and the neighborhood's mature landscaping is part of its character.
Slope can work for or against a lateral. Homes above the street often have plenty of fall to the main, which helps flow. Homes below street level may need the line to run a long way or at a different depth, and some may need a pump to lift wastewater. Either way, the camera footage and a locate are needed before any method is chosen.
How lot position can affect the lateral
| Lot position | What to ask about |
|---|---|
| House above the street | Steep sections, joint separation and root entry along the drop |
| House level with the street | Long runs with gentle slope; watch for bellies |
| House below the street | Line depth at the street and whether a pump is part of the system |
Specific to sloped lots
- Ask where retaining walls or steps sit over the line
- Check whether the lateral crosses a neighbor's lot or an easement
- Note large trees uphill and downhill of the route
- Ask how access pits would be dug on a slope
- Confirm permit needs with the City of Whittier
Which method might fit a hillside line?
- IfLine is round and well sloped with root entryThenLining may avoid digging on the slope.
- IfLine runs straight and needs full replacementThenPipe bursting with pits at the top and bottom may be discussed.
- IfLine is broken under a retaining wall or stepsThenAsk about access carefully; method depends on what can be disturbed.
Questions for the plumber
- Does my line cross any other property?
- How deep is it at the street?
- What surfaces or walls would be disturbed for each method?
