01Springfield (97477-97478)
Eugene's sister city across the river runs roughly half pre-war historic core east of the Mohawk and half post-war tract development pushing north and east toward Gateway. The historic-core lots near the Willamette and McKenzie confluence sit in flood-plain soil with shallow winter water tables, which means January excavations may need dewatering before the tank can be lifted cleanly. Springfield runs its own permit counter at City Hall on A Street, which is a different submission and inspection schedule than Eugene proper.
02Whiteaker (97402)
Eugene's oldest residential neighborhood is also our most access-constrained. Pre-1920 lots are tight, side yards are narrow, and tanks frequently sit under what became 1960s side additions or detached studio conversions. Most Whiteaker jobs use a mini-excavator and span two days rather than one, because access has to be opened, worked, and closed sequentially. There is rarely room to keep an open hole and a working excavator on the same lot at the same time. The investor and live/work mix means we coordinate scheduling with property owners who are typically also occupants.
03South Hills (College Hill, Fairmount, Crescent) 97405
The hillside neighborhoods south of 18th sit on Tertiary volcanic clay slopes that shape every part of the dig. Original tanks often sit in undisturbed cut soil while the access driveway is on engineered fill, which changes how spoil piles can be staged. Over-saturated South Hills clay can move when loaded heavily, and February excavations carry a different risk profile than August excavations on the same lot. Many newer additions and decks were built directly over original tanks, making abandonment in place more common in this quadrant than removal.
04Friendly and College Hill west of campus (97405)
The neighborhoods between U of O and the South Hills are dense with pre-war craftsman bungalows and four-square homes built between 1905 and 1935. Original 500-gallon tanks are the norm, often in front yards under mature landscaping that has obscured fill pipes and vent stubs over the decades. We almost always start these jobs with a magnetometer sweep before excavating. The student-rental conversion of single-family homes near the campus boundary means a meaningful share of decommissioning calls come from investor LLCs rather than long-tenured owners.
05Bethel and River Road (97402, 97404)
West Eugene and the corridor running north along the Willamette flood plain. Predominantly 1950s-70s tract development on flat alluvial soils, with easier excavator access than the South Hills, but with a winter-water-table issue that can require dewatering. Releases here tend to spread laterally before they are caught, the opposite of South Hills clay behavior, which means cleanup scope can be larger when it surfaces. Mid-century tract layouts often locate tanks within a few feet of foundation walls, a situation that requires careful excavator work to avoid undermining the slab.
06Coburg, Junction City, and the agricultural periphery
Small historic towns north of Eugene with farmhouse residential properties and a strong rural-edge presence. Older agricultural parcels often have undocumented secondary tanks beyond the residential heating tank (fuel storage for tractors, generators, or shop heaters) and we identify those during the site survey before pricing. Permitting moves to Lane County Land Management for unincorporated parcels, which is a different counter than the city departments handle.
07Cottage Grove, Creswell, Pleasant Hill (97424, 97426, 97455)
The southern Lane County corridor along I-5 and toward the foothills. Cottage Grove's historic timber-town downtown has dense pre-war residential stock that mirrors what we see in Eugene's Whiteaker; foothill clay soils east of town behave similarly to the South Hills clays of Eugene proper. Pleasant Hill and Creswell tend to run more rural, with farmhouse pad-mounted tanks more common than buried ones. Lane County permitting throughout for unincorporated parcels.
For Lane County properties not listed above we work the same way at the same standard. That includes Junction City, Veneta, Creswell, and Pleasant Hill on the Eugene-metro fringe; Glenwood between Eugene and Springfield; Lowell and Dexter near the reservoir; Marcola and the Mohawk Valley north of Springfield; and Walterville, Vida, and the Fall Creek corridor heading east into McKenzie River country. Same crew, same DEQ license, same Decommissioning Report standard regardless of which Lane County jurisdiction handles the permit.
