23rd Avenue valley

26 February 2013

Between the stream valleys occcupied today by 14th Avenue (originally named Commerce Street) and Fruitvale Avenue (Sausal Creek) is a subtle little valley that once had its own little creek. Now 23rd Avenue runs up its former course, diverting the street from the grid so typical of the rest of the neighborhood. The creek is shown on the 1877 map entering the Bay where the Embarcadero Cove Marina sits today. There seems to have been a shellmound a little south of there.

This view is looking up Foothill Boulevard where it crosses the valley. This is at the top of the marine terrace and the foot of the Fan. You can pretty much always tell where the Fan starts by following Foothill. The geologic map shows the valley splitting here with a spur running due north for a few blocks, filled with young alluvium.


This is looking across the valley farther uphill, on E. 17th Street where Garfield Park is. The valley is a bit deeper here, and it continues to deepen as you go uphill.


At 23rd and 23rd the creek split, with its northern fork running where Highland Avenue is today. The main fork continued straight, along 23rd Avenue, and petered out by E. 30th Street right next to the Central Reservoir, which is in the Sausal Creek watershed. The stretch where the divide between the two watersheds is most pronounced is occupied by a street named, unsurprisingly, Grande Vista.

This creek is entirely covered today.

Sneak creek peek

22 February 2013

Sausal Creek has escaped culverting in a large part of its course. Between Dimond Park and the freeway, it mostly runs through people’s back yards, but you can spot it looking downstream from MacArthur Boulevard across from Canon Avenue:


. . . and farther down, looking upstream from a spot at the intersection of Dimond Avenue and Montana Street.


It’s culverted from here all the way down to the end of Hickory Street, directly below the miserable house on McKillop Street. Maybe it’s safer to say that the creek is covered, because even this open stretch has walls hemming it in.
