Sewage Cleanup in Clackamas, OR: what we see locally
Clackamas is an unincorporated community in Clackamas County, about 10 miles southeast of downtown Portland, sitting east of I-205 along the Highway 212/224 corridor and just north of the Clackamas River. Rather than a traditional downtown, the area's identity is built around a handful of major anchors: Clackamas Town Center, one of the largest enclosed shopping malls in Oregon, a Kaiser Permanente Sunnyside Medical Center campus, and Camp Withycombe, an Oregon National Guard post at the foot of Mount Talbert that has operated continuously since it opened as the Clackamas Rifle Range in 1909 and was renamed for Governor James Withycombe in 1916. The 2010 census counted roughly 7,000 residents inside the community's old CDP boundary; more recent census cycles have redrawn that boundary into neighboring geographies, which is part of why Clackamas reads today as a commercial and institutional hub more than a single tracked town.
Housing here is scattered among the retail and institutional land rather than concentrated in a historic core. The Sunnyside neighborhood nearest the mall carries a mix of 1960s–80s single-family ranch homes and garden-style apartment complexes built from the 1990s onward — the Preserve at Sunnyside, built in 1991, is typical of that newer multifamily stock. Residential pockets farther from the retail corridor, toward Sunnybrook and the Webster Road area, run newer and lower-density.
Mount Scott Creek and Camas Creek both run through North Clackamas Park on the area's western edge, and a USGS stream gauge on Carli Creek sits just outside the retail core — three creek drainages threading through a landscape otherwise dominated by mall parking lots, big-box pads, and office and medical campuses. That mix of impervious surface and creek-adjacent low ground means stormwater runoff concentrates fast during sustained Pacific Northwest winter rain, a different pattern than the sump-pump flooding common in nearby subdivision-heavy suburbs.
Typical sewage cleanup scenario in Clackamas: Clackamas runs largely on separated sewer and stormwater infrastructure serving its commercial core, with aging lateral lines in the older Sunnyside residential pockets the most common source of root-intrusion backups. We handle Category 3 cleanup the same way whether the source is a residential lateral or a commercial building's main line.
