The MLK JHS campus (formerly Norte Del Rio High School) was constructed in 1954, adjacent to Arcade Creek. There is much to learn about the history and natural environment of this area.
This is an excerpt from the Salmon in Arcade Creek article published by the Sacramento Urban Creeks Council (http://www.sacto-ucc.org/ucc-salmon-arcade.htm):
Arcade Creek was once healthy and a very different kind of creek. It may or may not have supported Chinook salmon. As suburban development occurred in the Arcade Creek watershed during the last half of the last century, the creek was forced to carry high flows of water much more frequently than before. Rain from winter storms used to percolate into the ground; stormwater would run off into the creek only in very heavy or long-lasting storms that saturated the ground.
Now rainwater falling onto rooftops, streets, sidewalks, parking lots and other impervious surfaces flows quickly and efficiently through storm drains and into the creek. More erosion of the creek bank occurs under these frequent high-water conditions. One of the results - large quantities of soil that at one time formed the creek bank were and continue to be scoured away, ending up as silt on the creek bed. This accelerated bank erosion and siltation of the creek bed is bad news for spawning salmon and most other plants and animals native to Arcade Creek.
