A property is underlain by a 10m thick clay layer that undergoes consolidation. The consolidation coefficient is 1 x 10^(-8)m^2/s. The clay layer drains to a sand layer above and sits on top of impermeable bedrock. How long will it take (in years, rounding to the nearest year, with 3.1557 x 10^8 seconds/year) to reach 90% of the total expected settlement for this layer?
