Excavation in 97414 covers Broadbent and the rural agricultural parcels along the Coquille River and Hwy-242 between Myrtle Point and the Coast Range foothills east of Coos Bay. This is back-country dairy and ag country -- the Broadbent area supports multi-generation dairy operations, hay farms, and the long private-driveway parcels feeding the rural-route network. Most excavation work in 97414 is agricultural site prep, rural residential driveway rebuilds, and the septic and utility-trench work that comes with new construction on parcels too far from city services. Cojo dispatches Coos County jobs from our Hood River yard with summer dispatch, and the Coquille River salmon-stream setback paperwork is a real piece of the work scope.
What 97414 Excavation Jobs Actually Look Like
The 97414 footprint splits into three working zones. Agricultural site prep is the largest category -- dairy operation expansion, hay-shed and equipment-storage pad construction, ag-pond and field-drainage work, and the loading-dock and silo pad work that scales with operating size. The second category is rural residential -- long-driveway parcels needing access road rebuild, septic systems on older parcels where the existing system has aged past current code, and small-shop or pole-barn foundation pads. The third category is small commercial along Hwy-242 -- service stations, feed-supply, and the small retail anchoring the corridor.
Practical scope on Broadbent work tracks like this. A rural driveway dig runs 600 to 4,000 cubic yards because the access roads are long and serve substantial acreage. Septic systems run 50 to 150 cubic yards for the typical dairy or residential install. Ag-pond construction runs 1,000 to 8,000 yards depending on operational water-storage needs. We work off Coos County base maps, locate utilities through Oregon One-Call, and document hauled-off volume by truck count -- on dairy work, much of the spoil can stay on-parcel as field fill, which keeps the haul cost down.
Coos County Soil and Coquille Watershed Reality
Broadbent sits on Coquille River alluvial deposits -- mostly silty clay loam with sand and gravel bands deposited by historic river action. The valley-floor subgrade is moderate for excavation, but the high water table and the proximity to the Coquille River both shape what can be done and when. Winter wet season -- October through April -- raises the perched water table into the top 24 inches of soil on many valley parcels, and any excavation scheduled outside the May-to-October window will smear in saturated clay and turn haul roads into bog.
The Coquille River salmon-stream setback is the biggest paperwork constraint here. Removal-fill within 100 feet of the ordinary high-water line requires Oregon DSL authorization, and ODFW review applies to any work that delivers sediment to fish-bearing water. The Coquille Indian Tribe has cultural-resource interests in the river corridor, and parcels with documented archaeological context require SHPO coordination. Dairy operations often have Oregon Department of Agriculture confined animal feeding operation permits that affect how site work is reviewed, and we coordinate with the operation's existing CAFO documentation when scope requires.
Industry Cost Picture for a 97414 Excavation Job
Cost in Broadbent is driven by equipment mob distance from any Cojo yard, the Coquille River setback paperwork, the CAFO documentation coordination for dairy work, and whether spoils stay on-parcel or have to be hauled off.
Industry Baseline Range
| Project Type | Cost Per Cubic Yard | Typical Total |
|---|---|---|
| Rural driveway prep, 500 to 1,500 ft | $11 to $24 | $7,000 to $35,000+ |
| Septic system, tank and drainfield | $15 to $40 | $9,000 to $30,000+ |
| Dairy operation pad / hay shed | $10 to $22 | $8,000 to $50,000+ |
| Ag pond construction | $8 to $20 | $10,000 to $80,000+ |
| Utility trench, 100 to 500 ft | $18 to $50 | $4,000 to $25,000 |
Current Market Reality
Coos County excavation pricing has run 25 to 40 percent above 2019 baseline since 2022 fuel and equipment-cost increases. Broadbent-area haul cost is real because the material yards are in Coos Bay or Roseburg and the round trip eats labor hours. A rural driveway prep the baseline frames at $12 a yard is more likely $16 to $20 here today. Septic systems on high-water-table parcels commonly run 40 to 60 percent over baseline because of the soil-evaluation cycle and the drainfield design adjustments for perched aquifer. We do not quote 97414 excavation over the phone -- a real number requires a site walk and a soil percolation test for septic work. For broader context, see our excavation in Coos County guide.
Permits, Coquille Setback, and the CAFO Process
Coos County Public Works runs unincorporated 97414 permits, with septic systems going through Coos County Environmental Health for soil-evaluation testing and design review. Single-family-dwelling permits run through county planning. The Coquille River setback piece requires Oregon DSL paperwork for any removal-fill within 100 feet of the ordinary high-water line, and ODFW review for any work that delivers sediment to fish-bearing water.
CAFO permitting through the Oregon Department of Agriculture applies to confined dairy and livestock operations, and site work that affects manure handling, runoff routing, or animal-access patterns has to be reviewed against the operation's existing CAFO documentation. We coordinate that review with the operation owner before quoting. DEQ 1200-C stormwater permitting applies if disturbance exceeds one acre. Coquille Indian Tribe cultural-resource coordination applies on parcels with documented archaeological context.
How To Hire For This Zip
Ask three things of any 97414 bidder. First: who is pulling the Coquille River setback or DSL paperwork, and is the cost in the bid? Second: if my project is on a CAFO-permitted dairy operation, are you familiar with the CAFO review and how site work integrates with that documentation? Third: where are spoils going, and what is the disposal cost added per yard if they have to leave the parcel? A contractor who shrugs at the CAFO coordination question on a dairy parcel has not done enough Coos County agricultural work.
Cojo runs Broadbent work alongside our Camas Valley sealcoating nearby routes and our sealcoating in Coos County crews, so a parcel that needs site prep plus driveway paving plus follow-on seal goes through one company. Equipment list is on our excavation services page.
