Segment Analysis 4 <br />4-9 <br />4.2 SEGMENT 2: HEGENBERGER ROAD TO 98TH AVENUE <br />Segment 2 runs from north of Hegenberger Road to north of 98th Avenue. It <br />is located within the City of Oakland. There are approximately 13-foot wide <br />maintenance roads on both sides of the channelized Creek. The surface of <br />the maintenance road is gravel and slopes down to the San Leandro Creek. <br />There is vegetation on the slopes. The route is relatively shaded with fully- <br />grown trees along the maintenance roads on both sides of the San Leandro <br />Creek. Recently, wetland restoration efforts on the banks and desilting of the <br />channel led to the change in the configuration of the banks from a direct <br />slope to a stepped slope in certain parts of this segment as shown in Figure <br />4-4. This enables better growth of vegetation on the banks. The channel is <br />designed with a 100-year flood capacity. <br />The location of the Airport Plaza on the south side of the San Leandro Creek <br />at the end of this segment is a strong opportunity for the trail users. This plaza <br />has businesses, restaurants and coffee shops that are conducive to such a <br />development. On the north side of the San Leandro Creek, there are large <br />parcels of open land and a large parking area used for airport parking. A <br />walkway through an open field could connect this segment to Brookfield <br />Village, a neighborhood build during the 1940s. It is located north of the <br />project area near I-880 in the City of Oakland. <br />Crossing at Hegenberger Road is a challenge as it is a major arterial with <br />high speeds, heavy traffic volumes, and elevated BART tracks. The closest <br />existing signalized at-grade crossing is 800 feet northeast of the trailhead at <br />Hegenberger Loop. A relatively straight crossing of Hegenberger Road from <br />the trailhead will require dealing with a left-turn lane that currently provides <br />access to a large airport parking area on the east side of the roadway. <br />FIGURE 4-7: HEGENBERGER ROAD <br />FIGURE 4-6: CREEK MAINTENANCE ROAD <br /> FIGURE 4-5: PROFILE- PREVIOUS AND CURRENT <br />55
