Alum Rock at Pleasant Ridge

Summary: Alum Rock
• About 50,000 SF (1.1 acres) arterial roadway• Additional 72,000 SF (1.6 acres) residential streets• Plus portion of residential lots draining to street• 3 bioretention facilities totaling about 5230 SF• Need for traffic calming and pedestrian access
![Page 17: Rapid Project Identification and Conceptual Design for Green Infrastructure Dan Cloak, P.E.April 8, 2015.](https://reader031.fdocuments.in/reader031/viewer/2022032200/56649cb75503460f9497cd68/html5/thumbnails/17.jpg)
Some preliminary insights
• This is a craft• Potential sites are easy to find
– But are not available in all areas
• Subtle differences in elevation determine feasibility and cost
• Creating changes to surface drainage will be a key part of many projects– Overlays– Removing catch basins– Using trench drains

Eight Projects
Location Type
1 Alum Rock Ave. Arterial Street/Residential Streets
2 Commercial St. Old Industrial Street and Facility Entrance
3 Hedding Street Arterial - Disperse runoff to airport approach area
4 San Felipe Road Suburban Arterial
5 N. 5th St. Bioretention facilities in residential parkway strips
6 St. James Alleyways Permeable Pavement and Infiltration Trenches
7 South Grant St., San Mateo
Curb extensions/bulb outs in mixed-use area
8 River Oaks Pump Station
Divert dry weather and low flows to bioretention
