00 73 05 - 2 asphalt road on the levee crown on both sides of the H Street Bridge. There are unpaved dirt ramps on both sides of the bridge connecting the levee crown to an asphalt pedestrian path on the waterside of the levee, and an asphalt ramp down to a path on the landside that runs parallel to Fair Oaks Boulevard. The length of the "window" is approximately 151 feet. The waterside and landside slopes are approximately 4:1 and 3:1 (H:V), respectively. H Street becomes Fair Oaks Boulevard at the right bank of the river.

Site L7 is directly across the river from Site R7. The existing left bank (west) levee of the American River at Site L7 is approximately 12 feet in height (as measured from the landside toe) with a crown width of approximately 18 to 20 feet in the levee section. There is an asphalt road on the levee crown on both sides of the H Street Bridge. There are unpaved dirt ramps on both sides of the bridge connecting the levee crown to an asphalt pedestrian path on the waterside of the levee, and an asphalt ramp down to a path on the landside that runs parallel to H Street. The length of the "window" is approximately 325 feet. The waterside and landside slopes are both approximately 2.5:1 (H:V).

There is a 12" steel water pipe suspended from the bottom of the H Street Bridge at both sites. There are also overhead electric lines and power poles at both sites. At Site L7, there is an underground 72" steel storm drain pipe that connects to a vault on the waterside slope of the levee, just south of the H Street Bridge.
