Commercial asphalt paving in Hood River is our home market. Cojo dispatches from our Hood River HQ, and the Heights retail district, the downtown waterfront lots, the airport-industrial park east of town, and the orchard-frontage commercial sites in the upper valley all sit inside a 15-minute drive. Property managers here usually know us already; this article is for the ones building a 2026 budget who want a real scope-and-sequence reference before requesting a bid. The right scope for any commercial lot is overlay, mill-and-overlay, or full replacement, and the decision depends on the base condition revealed by a site walk and core samples -- not by what looks worst from the curb.
Gorge Climate and Columbia Basalt Sub-base
Hood River sits at the west end of the Columbia River Gorge where the wet Cascade climate meets the dry eastern shadow. Annual rainfall runs 30 to 35 inches, summers are warm and breezy, and winters bring 25 to 35 freeze-thaw cycles -- harder than the Willamette Valley, softer than Klamath Falls. The gorge wind is a constant: sustained 30 to 50 mph east winds for days at a stretch, especially in late winter and early spring.
Underneath most Hood River commercial lots is decomposed Columbia River Basalt, often within 12 to 24 inches of the surface. That basalt sub-base is structurally excellent -- it doesn't pump, it drains well, and it carries heavy loads. Lots built with proper basalt-aggregate base perform substantially better than valley lots of the same age. The exception is filled sites near the river or on bench cuts in the Heights, where imported fill of variable quality can underperform native basalt.
Failure modes in this climate are dominated by UV oxidation and freeze-thaw expansion at any unsealed crack. Wind-driven dust also accelerates surface abrasion on lots near gravel staging areas. We assess all three during a site walk.
Scope Decisions: Three Real Options
The right scope matches the base and surface condition revealed by a site walk and selective core samples.
- Overlay (2-inch lift): works only on a sound base with shallow oxidation cracking. Ten to fifteen year lifespan in the Hood River climate.
- Mill-and-overlay (mill 2 inches, lay 2 inches): the standard scope for Heights retail and downtown lots with surface distress over a still-functional base. Fifteen to twenty year lifespan.
- Full replacement: needed where the base has failed -- pumping at cracks, alligator cracking through the lift, persistent birdbaths. Twenty-five to thirty year lifespan if drainage is corrected.
For a typical Heights retail anchor pad, the scope often ends up phased: mill-and-overlay in the drive lanes, full replacement at loading-dock and trash-compactor zones, sealcoat-and-restripe in the parking stalls. Phasing each section into the right treatment is how the budget stays honest.
Industry Baseline Range
| Project Type | Cost Per Sq Ft | Typical Total Cost |
|---|---|---|
| Overlay (2" lift) | $2.00 to $5.00 | $20,000 to $80,000+ |
| Mill-and-overlay | $3.00 to $7.00 | $30,000 to $150,000+ |
| Full replacement (10K sq ft) | $4.00 to $10.00 | $40,000 to $200,000+ |
| Heavy-duty truck section | $5.00 to $12.00 | varies by zone |
| Mobilization (local) | line item | $0 to $500 |
Current Market Reality
The baseline assumes a flat lot, sound base, no stormwater retrofit, and no ADA non-compliance work. Pre-2010 Hood River commercial lots typically need ADA curb-ramp and accessible-stall updates as part of any restripe. Hood River County stormwater rules can add treatment work to any project that materially changes impervious area, especially on lots near the Hood River main stem or the waterfront. Mobilization for our home market is effectively zero -- we carry it as a line item rather than padding the per-square-foot rate. For broader Oregon pricing context, see our Oregon paving cost guide.
Sequencing Around Tenants, Wind, and Tourism Traffic
Hood River retail and waterfront tenants run on a tourism-driven schedule: summer is the high season, weekends are the high days. We sequence accordingly. For Heights retail, we phase by zone with overnight pours where Hood River County permits, weekend phasing for larger lots, and lane-by-lane closures for drive aisles. We monitor the gorge wind forecast and stage placement around east-wind events to keep fines on the mat where they belong.
A few operational rules we work to:
- April through October is the safe window for hot-mix mat placement.
- Sealcoating wants 60 degrees F overnight; that puts our window from mid-May through mid-September.
- Striping follows paving on the same mobilization. Layout standards live on our commercial striping page.
- Gorge east-wind events get watched. We pull the pour if wind risk threatens fines bonding.
Five-Year Preservation Plan
A standard preservation sequence for a Hood River commercial lot in fair condition runs crack-seal-and-sealcoat at year zero, hot-pour crack-seal every fall, sealcoat-and-restripe at year three or four, mill-and-overlay at year twelve to fifteen, and full replacement at year twenty-five to thirty if drainage is corrected at the overlay phase. The cadence is looser than Klamath Falls because the basalt sub-base survives longer, and tighter than coastal Oregon because of the freeze-thaw cycling.
Most property managers want the preservation schedule attached to the bid so ownership sees the funded path. Cadence specifics are on our Hood River sealcoating and commercial sealcoating pages, and broader portfolio context on our asphalt maintenance program documentation.
What a Real Bid Should Include
A defensible commercial paving bid for a Hood River property lists every component the work will touch. Missing components push surprise costs into the project after work starts.
- Total area, segmented by treatment zone (overlay, full replacement, sealcoat, restripe).
- Structural-section spec by zone, with heavy-duty truck zones at airport-industrial sites called out separately.
- Drainage scope for Hood River County stormwater compliance, particularly for waterfront and orchard-frontage sites.
- ADA scope (curb-ramp updates, accessible-stall counts, ramp slopes meeting current standards).
- Sealcoating and striping line items.
- Warranty terms with specific exclusions called out.
- Mobilization as a separate line item (effectively zero for our home market; a Portland contractor showing zero is hiding the travel).
- Phasing schedule with cure times and back-in-service dates.
- Gorge-wind contingency: how the contractor handles east-wind events during placement.
- Permits and inspection coordination.
- Closeout documentation (as-built drawings, photo records, structural specs).
Line your bids up by these components first, then by price. Local knowledge of gorge conditions matters more here than in any other Oregon market we serve.
Why Cojo for Hood River Commercial Work
Cojo has been a licensed Oregon contractor since 2009 (CCB licensed and insured). Hood River is our home market, our equipment yard, and where our crews dispatch from. We run our own crews on every job rather than subbing out, and the local mobilization means we can sequence around tenant schedules and weather windows tighter than a contractor coming up from Portland.
If you manage a lot in the Heights, downtown Hood River, the waterfront, or the airport-industrial corridor, call our Hood River office. We'll walk the site, core where the base looks suspect, scope each zone, and hand you a phased bid with mobilization, sequencing, and warranty terms in writing.
