Illegal Grading?


Grading at Seeno Company San Marco Project, February 2008

Illegal Grading

San Marco grading looking west on Hwy 4; the center area (see arcing erosion berms) was a creek and canyon which have been wiped out of existence by grading 400-500 feet in width. Avila Road dead ends at a turn around at center right, at the edge of the San Marco property. (Scott Hein-SMD)

This (presumed) unpermitted grading has wiped out a creek and canyon from Hwy 4 all the way to the Los Medanos ridgeline overlooking Concord. Avila Road dead ends at right. The graded area is up to 500 feet in width. The upper hills to the left and right are also proposed for development by the Seeno Companies (Scott Hein-SMD)

Upper canyon slopes exceed 10% in steepness, and require grading permits. These new grading cuts are already witnessing unanticipated slumping and erosion. Tributary drainages have also been damaged by grading. The Avila Road turn around is visible at bottom right. The Los Medanos hills above at left and right are also proposed for development by the Seeno Companies. (Scott Hein-SMD)

The highest grading in Pittsburg. Although the most prominent landmark in western Pittsburg, the City of Pittsburg does not recognize the Los Medanos hills as a major or a minor ridgeline. The west (right) side of the 860' knoll drains into Concord and the Concord Naval Weapons Station, at right. The Los Medanos hills in foreground and center are also proposed for development by the Seeno Companies. (Scott Hein-SMD)

The highest grading in Pittsburg-construction on this knoll would be even more visible. View of the graded 860' knoll in San Marco from Concord, with Pittsburg beyond. The Los Medanos hills left and right are also proposed for development by the Seeno Companies, overlooking and draining into Concord. (Scott Hein-SMD)

Red Star is the graded 860' knoll. The Los Medanos hills (green) left and right are also proposed for development by the Seeno Companies, overlooking and draining into Concord. (Google overlay by Troy Bristol-Save Mount Diablo)

Black Star is the graded 860' knoll in the San Marco project, shaded red. Pittsburg's General Plan does not recognize any of its Southwest hills as Major OR Minor ridges, even though the Los Medanos hills are the most prominent division between Central and Eastern Contra Costa. The Los Medanos hills in purple are also proposed for development by the Seeno Companies, adjacent to the Concord Naval Weapons Station. (General Plan Map overlay by Troy Bristol-Save Mount Diablo)
