N9104RCessna 180A

The pilot stated that while in flight he encountered frequent isolated rain storms. During the approach there was light rain with good visibility. The pilot reported a normal touchdown and a reduction in forward visibility as the light rain became heavy rain. At approximately 150 feet from the end of the airstrip the pilot saw an 18 inch elevated driveway and applied heavy braking and right rudder resulting in a low speed skid. The left main gear impacted the driveway and the aircraft continued to slide over the road bed. The impact resulted in substantial damage to the left wing, fuselage, and firewall.
