The Clark District is the historic residential area south of downtown Forest Grove. Central School sits near its west edge and Rogers Park near its east edge. If you have a plumbing problem there, call (503) 974-3329, describe it, and the dispatcher will confirm your address and send a plumber.
The district holds 178 historic sites from many eras. That variety is the useful fact for plumbing, and it is laid out below with what the records do not tell us.
What the public record says about the Clark District
The City of Forest Grove describes the Clark District as a National Register historic district south of downtown, created in 2002, with 178 historic sites. The National Park Service record lists it as roughly bounded by 18th Avenue, 16th Avenue, A Street and Elm Street. Another published description puts the north edge at 19th Avenue, so the exact line is not settled in the sources we checked.
The district is named for Reverend Harvey Clark and his wife Emeline. Clark donated much of the land to Tualatin Academy, now Pacific University, as an endowment, and it was first platted into one-acre lots. Houses were built for residents in many occupations, which is why styles run from Second Empire to Bungalow.
Rogers Park, at 2421 17th Avenue, sits on the east side and has a playground, restrooms, picnic tables and a walking path, according to the City.
Why one house can differ from the next
Land that began as one-acre lots was divided over time, so houses from different decades sit side by side. For plumbing, no single answer fits the district. One house may have been repiped and its neighbor may not. A kitchen added in one decade and a bathroom added in another can each tie into the system their own way. The honest approach is to diagnose the house in front of you.
Start with the symptom. A wet spot you cannot explain or a water bill that jumped points to leak detection. A heater that struggles is a water heater repair question first. Drips and stiff handles are usually faucet repair. If someone suggests replacing supply lines, repiping explains the choices, and a plumber should show you the pipe before recommending it.
Hidden leak or a house with a long history in the Clark District? Call and describe it.
Call (503) 974-3329Cold snaps and a shutoff you can find
NOAA's 1991 to 2020 normals for the Forest Grove station put the average January low at 32.6 F, so freezing nights happen. A pipe that freezes can split, and burst pipe repair covers the fix. Know where the main valve inside your house is before you need it, and never turn the city meter.
A plumbing permit is required in Oregon to replace a water heater or to change piping that runs inside walls, ceilings or floors. The City's Community Development staff at 503-992-3229 can say what applies, including whether the district adds any review for your address.
What we do not know
- Which pipe materials are in any given house, or when each part was replaced.
- The exact northern edge of the district, since sources disagree between 18th and 19th Avenue.
- Whether houses inside the district have more plumbing trouble than houses outside it.
- How many of the 178 sites have had interior plumbing remodels.
The way to settle those questions for your home is to look, not to assume from the style or the date on the porch.
