Palo Alto requires erosion and sediment control on construction sites under its grading ordinance and NPDES stormwater permit, with seasonal BMPs mandatory during the October-April rainy season.
Erosion and sediment control in Palo Alto is governed by the grading provisions of Municipal Code and the NPDES Construction General Permit for sites of one acre or more. All construction projects disturbing soil must implement Best Management Practices (BMPs) including silt fences, fiber rolls, inlet protection, stabilized construction entrances, and concrete washout containment. The rainy season (October 1 through April 30) triggers enhanced requirements, with pre-storm preparation required when precipitation is forecast. Grading permits are issued by Public Works and require erosion control plans for projects above specified thresholds. Discharges of sediment-laden water to storm drains or waterways violate state and federal clean water laws. Hillside properties face additional scrutiny due to slope stability concerns. Violations may trigger stop-work orders, civil penalties, and mandatory remediation. Stabilization of disturbed areas is required within specified timeframes after grading ceases.
