What the Terrace Historic District is
The City of Colton lists Terrace among its historic districts on a Planning Department map and landmark list. The city says you can check whether an address sits in a historic district with its online Property Viewer. We have not found a published street boundary in text form, so we do not describe one here.
Real estate data sites describe the area as mostly single-family homes and small apartment buildings, with many homes built between 1940 and 1969 and some built later. Treat that as a general picture from a data aggregator, not a survey of any street. Your own house may be older or newer than its neighbors.
What is known and what is not
We separate confirmed facts from open questions so you know where to ask.
| Topic | Status | Where to check |
|---|---|---|
| District is on the City of Colton historic map | Confirmed by the city's Planning Department map | City Property Viewer |
| Exact street boundary | Not confirmed in text | City Planning Division |
| Year your house was built | Varies by property | County assessor record |
| Pipe material in your house | Not publicly documented | Inspection of your own pipes |
| Sewer or water line condition | Not publicly documented | A camera inspection or the city |
The Planning Division is at 659 North La Cadena Drive and can be reached at (909) 370-5079.
Why age matters, without guessing at your pipes
Houses from the mid 1900s can have had several rounds of plumbing work. Some pipes may be original and some may be new. We will not tell you what is inside your walls without seeing it.
What we can say in general is that older supply lines and drain lines get more attention during a plumbing visit. A plumber will look at shutoff valves, visible pipe material, water pressure and how many repairs the system has had. Those checks matter more than the year printed on a listing.
Water heaters in an older Colton home
Colton's city water is hard. The city's water quality report shows total hardness averaging about 207 mg/L, roughly 12 grains per gallon. Scale from hard water can build up on a tank's bottom and heating parts over time.
If you replace a water heater, the City of Colton requires a permit. The owner or an insured California-licensed contractor can pull it, and the city page lists the forms. A change-out in the same spot gets one final inspection. Gas to electric conversion is not allowed under that alteration path.
In a historic district, ask the Planning Division whether any exterior work, such as a new vent or an outdoor installation, needs separate review. We do not know your parcel's rules.
Before you call about a plumbing problem
These steps help any plumber understand the job faster.
- Find the main shutoff. Know where water enters the house so you can stop a leak quickly.
- Note when it started. A slow drain over weeks is a different problem from a sudden backup.
- Photograph the area. A picture of a wet wall or a rusty fitting saves time on the phone.
- Check the district question. If the work is visible from the street, ask the city before you start.
- Call 811 before digging. California law requires a DigAlert call at least two working days before any dig.
