Segment Analysis 4 <br />4-17 <br />4.4 SEGMENT 4: RAILROAD / I-880 TO AMTRAK RAILROAD <br />Segment 4 runs from west of the railroad tracks and Interstate 880 overpass to <br />west of the existing Amtrak railroad tracks. This segment of the San Leandro <br />Creek is relatively challenging compared to previous sections. There is an <br />existing active railroad and an overpass for I-880 near the western end of <br />this segment. The railroad is located approximately 15 feet above the San <br />Leandro Creek bed. <br />There is also an open concrete stormwater channel that runs parallel to the <br />train tracks on the east side of the track and ends one block short from Edes <br />Avenue. The maintenance road on the east side of this channel owned by <br />City of Oakland, is approximately 16 feet wide, more than wide enough to <br />potentially act as an alternative route for the trail alignment. <br />The San Leandro Creek configuration changes drastically in this segment. <br />The maintenance road is no longer located on the top of the bank, but <br />approximately two to three feet above the bed of the San Leandro Creek. It <br />ends a couple of blocks before the railroad tracks in the east. The maintenance <br />road is approximately ten feet wide and is a rough paved concrete road. The <br />channel itself is trapezoidal in shape. The maintenance road is in the floodplain <br />and may need to be restricted for walking or biking during the rainy season or <br />during floods. Various environmental agencies that have jurisdiction over this <br />area typically restrict any kind of development below an existing top of bank <br />in a riparian corridor such as this one. <br />There is a large open space below I-880 that could be used creatively. Survey <br />records show that the right-of-way under 880 is owned by Alameda County <br />Flood Control but Caltrans, does have an easement for maintenance. While <br />there are a variety of land uses in this segment, the majority of the land use <br />is residential, especially on the south side of the Creek. The Madison Park <br />Academy, Sobrante Park Elementary School, Sobrante Park and Aspire <br />Lionel Wilson College Preparatory Academy are located on the north side <br />of the Creek. However, there is no direct access to the San Leandro Creek. <br />There are also two cut-through routes in this segment: one connecting 105th <br />Avenue to Madison Park Academy and the other connecting 105th Avenue <br />FIGURE 4-17: CREEK MAINTENANCE ROAD <br />FIGURE 4-16: SEGMENT 4 PROFILE <br />FIGURE 4-15: STORMWATER CHANNEL <br />FIGURE 4-14: RAILROAD WEST OF SEGMENT 4 <br />63
