Santa Clara County Municipal Code Part 6 Erosion Control

All grading plans shall include the retained registered civil engineer's and/or landscape architect's recommendations for erosion prevention and sediment control measures.

Erosion control measures are required on-site year round. All planned erosion prevention and sediment control measures shall be installed by the time of the initial "grade stake" inspection. Approval for phased erosion control measure installation can be requested of and granted by the Grading Official prior to grading or construction permit issuance.

Grading projects that are started but not completed by October 1 of each year are to be "winterized" by installation of planned erosion prevention and sediment control measures, which shall be maintained in good repair at the satisfaction of the County grading inspector through the April 15 following, and until the project is completed.

(Ord. No. NS-1203.120, § 1, 4-9-13)

Adequate erosion and sediment controls shall be installed to minimize damage to all disturbed areas during construction.

(Ord. No. NS-1203.120, § 1, 4-9-13)

Adequate provision shall be made to minimize damage to the face of cuts and fills. Down slopes shall be protected from surface water runoff from above by dikes, swales or cut-off ditches, or other measures, as needed.

(Ord. No. NS-1203.120, § 1, 4-9-13)

Dikes, swales and ditches, when required, shall be designed and constructed to control runoff and erosion from graded areas. Where concentrated drainage discharges onto natural ground, effective measures shall be taken to dissipate the energy and, where practical, release the accumulated waters as sheet flow, unless the discharge is into a storm sewer or natural watercourse.
