About Cottage Grove

Cottage Grove sits at the southern tip of the Willamette Valley where the valley floor transitions into the Calapooya Mountains to the south and east. The city is positioned at the confluence of the Row River and the Coast Fork of the Willamette River, creating a landscape shaped by river alluvium and foothill terrain. Soils in the Cottage Grove area include silty clay loams on the valley floor and gravelly loams near the river channels, with heavier clay soils appearing on the surrounding hillsides. The river-influenced soils generally drain well but can experience seasonal flooding in low-lying areas near the Coast Fork, while the clay hillside soils require careful site grading and drainage engineering. Properties east of town toward Dorena Lake sit on increasingly rocky terrain with shallow soils over bedrock.

The City of Cottage Grove Community Development Department handles permits within city limits, while surrounding rural properties fall under Lane County Land Management. Cottage Grove has residential zones that permit manufactured home placement on individual lots, and several manufactured home communities operate within and near the city. Lane County's rural residential and farm-use zones in the Cottage Grove area generally allow manufactured homes, and many rural properties rely on septic systems and private wells. We coordinate with both jurisdictions and manage the complete permitting process, including manufactured dwelling installation permits through the Oregon Building Codes Division.

Cottage Grove is known as the Covered Bridge Capital of Oregon, with six historic covered bridges in the area including the Chambers Railroad Bridge, the only remaining covered railroad bridge west of the Mississippi. Dorena Lake, a U.S. Army Corps of Engineers reservoir on the Row River east of town, and the Row River Trail draw visitors and residents to the area. The South Lane School District operates several schools in the community, including Cottage Grove High School. Key residential areas include neighborhoods along Row River Road, the Silk Creek area south of town, the London Road corridor toward Dorena Lake, and the Coast Fork valley north toward Creswell. Local employers include Weyerhaeuser, the school district, and Cottage Grove Community Hospital.

From our Jefferson headquarters, Cottage Grove is approximately 1 hour and 20 minutes south via Interstate 5, a distance of about 80 miles. Cottage Grove is the farthest south we regularly travel in Lane County, and we coordinate projects here alongside our work in Creswell and the greater Eugene-Springfield area to maximize efficiency. Exit 174 off I-5 provides direct access to the city, and the Row River Road corridor east of town connects to the rural properties around Dorena Lake where we also work.

Cottage Grove has historically been a timber and mining community, with the Bohemia Mining District in the mountains to the southeast drawing prospectors in the late 1800s. Today, the community offers affordable housing compared to the Eugene-Springfield metro area, and manufactured homes are a popular choice for buyers and property owners looking for quality housing at a reasonable cost. The combination of rural acreage, scenic river valley setting, and proximity to outdoor recreation at Dorena Lake and the Row River Trail makes Cottage Grove attractive to families and retirees seeking a quieter pace of life without being far from urban amenities.
