How does Washington compare with nearby states for gravel parking lots?
Washington is about 10% above the national average for gravel, and ranks 41st least expensive of the 50 states we benchmark. The table compares it with other West Coast states on install cost and 15-year cost of ownership.
| State | Est. install (per sq ft) | Est. annual maintenance (per sq ft) | Est. 15-year cost (per sq ft) | Vs national average |
|---|---|---|---|---|
| Washington (this page) | $0.60–$3.00 | $0.14 | $3.96 | +10% |
| California | $0.66–$3.30 | $0.16 | $4.36 | +21% |
| Oregon | $0.58–$2.90 | $0.14 | $3.83 | +7% |
| West Virginia | $0.48–$2.40 | $0.12 | $3.17 | -12% |
| Wisconsin | $0.54–$2.70 | $0.13 | $3.56 | -1% |
| Wyoming | $0.52–$2.60 | $0.12 | $3.43 | -4% |
All figures are Wins Parking planning estimates for construction scope only; design, permitting and stormwater typically add 15–25%.
Nationally, gravel ranges from $0.43–$2.15 per square foot in Mississippi to $0.86–$4.30 in Hawaii. On a 100-stall lot of about 35,000 square feet, building in Washington instead of at the national midpoint adds about $5,845.
Which parking lot surface costs least over 15 years in Washington?
Gravel has the lowest estimated 15-year cost in Washington at about $3.96 per square foot, while gravel is cheapest up front at $0.60–$3.00. Concrete lasts longest, at 30+ years.
| Surface | Est. install (per sq ft) | Typical lifespan (years) | Est. annual maintenance (per sq ft) | Est. 15-year cost (per sq ft) |
|---|---|---|---|---|
| Asphalt | $3.60–$8.40 | 15-20 | $0.10 | $11.10 |
| Concrete | $7.20–$14.40 | 30+ | $0.04 | $12.42 |
| Gravel (this page) | $0.60–$3.00 | 5-10 | $0.14 | $3.96 |
Wins Parking planning estimates, construction scope only.
Side by side in Washington: asphalt $3.60–$8.40 to install and $11.10 over 15 years; concrete $7.20–$14.40 to install and $12.42 over 15 years; gravel $0.60–$3.00 to install and $3.96 over 15 years. Gravel suits rural, low-traffic or overflow areas in Washington; it does not meet ADA surface rules for accessible stalls, so most commercial lots pave at least the accessible route.
What local conditions should a Washington gravel budget plan for?
In Washington, the main ones are freeze-thaw cycles, drainage and strict stormwater rules. Each can move a bid toward the top of the $0.60–$3.00 range.
Freeze-thaw: water that enters cracks expands when it freezes, so Washington lots crack faster than lots in warm states. Expect regrading and fresh aggregate after each spring thaw.
Drainage: wet seasons in Washington mean more inlets, underdrains or detention than a dry-state lot of the same size.
Stormwater: Washington is among the stricter states for stormwater, so detention, water-quality treatment and permit time add cost beyond the construction range above.
Timing: gravel can be placed in cold weather but not on frozen ground, so most Washington work runs from late spring to mid-fall.
What drives gravel parking lot costs in Washington?
Climate and labor. Wet winters, moderate freeze-thaw, stormwater regs among strictest.
Our Washington index moves the national gravel baseline about 10% above the national figure. Material haul distance, prevailing-wage rules on public projects and the length of the paving season all push the number; the Federal Highway Administration's construction cost index tracks how those inputs move nationally.
What does a typical Washington gravel lot cost to build?
At about 350 square feet per stall including drive aisles: a 50-stall lot (17.5k sq ft) budgets at $10,500–$52,500; a 100-stall lot (35k sq ft) budgets at $21,000–$105,000; a 250-stall lot (87.5k sq ft) budgets at $52,500–$262,500, construction scope only.
Add 15–25% for civil design, permitting, stormwater detention and accessible-route work. Over 15 years, maintenance on a 100-stall gravel lot in Washington adds roughly $73,500 at $0.14 per square foot a year.
Which permits and standards apply to a Washington parking lot?
Local site plan and grading approval come from the city or county. Washington State Department of Transportation (WSDOT) publishes the state's standard specifications for asphalt and aggregate work, which many local codes reference, and permits any access onto state highways. Projects disturbing one acre or more need construction stormwater (NPDES) coverage, and accessible stalls must follow the ADA Standards.
