North Coast Community Watershed Project

About 8,000 houses are not on a public water system

43,000 houses in Clatsop and Tillamook

minus 35,000 taps reported by cities and water districts

leaves about 8,000 houses on a well, a stream, or water brought in by truck.

Oregon has paper on 5,373 wells in these creeks. The rest of the 8,000 is the gap: no well log yet, a stream tap, a truck, or a house the lists do not match.

What the map is coloring

The colors on the map are still the older creek lists: houses outside city limits, well logs, and stream water rights. City limits are not a water district. Most houses outside town still sit on a district pipe, which is why 22,689 outside city limits is much larger than the 8,000. The 8,000 is the two-county first pass. It is not split onto each creek yet.

Housing units are Census figures for 2025. Taps are OHA community-system connections for the cities and districts in both counties. Parks, camps, and schools were left off. A building with many apartments is one taxlot and often many taps; there are not enough of those here to flip the 8,000. Year built, well date, pipes, and forestry spray are not on this map yet.
